Objectives: Current resuscitation guidelines recommend target chest compression depth (CCd) of approximately 4cm for infants and 5cm for children. Previous reports based on chest CT suggest these recommended CCd targets might be too deep for younger children. Our aim was to examine measurements of anterior-posterior chest diameter (APd) with a laser distance meter and calculate CCd targets in critically ill infants and children., Design: A retrospective descriptive study., Setting: Single-center PICU, using data from May 2019 to May 2022., Patients: All critically ill children admitted to PICU and under 8 years old were eligible to be included in the retrospective cohort., Interventions: None., Measurements and Main Results: The chest APd measurements using a laser distance meter are part of our usual practice on the PICU. Target CCd and the over-compression threshold CCd for each age group was calculated as 1/3 and 1/2 of APd, respectively. In 555 patients, the median (interquartile range) of the calculated target CCd for each age group was: 2.7 cm (2.5-2.9 cm), 2.9 cm (2.7-3.2 cm), 3.2 cm (3-3.5 cm), 3.4 cm (3.2-3.6 cm), 3.4 cm (3.2-3.6 cm), 3.6 cm (3.4-3.8 cm), 3.6 cm (3.4-4 cm), and 4 cm (3.5-4.2 cm), for 0, 2, 3-5, 6-8, 9-11, 12-17, 18-23, 24 to less than 60, and 60 to less than 96 months, respectively. Using guideline-recommended absolute CCd targets, 4 cm for infants and 5 cm for children, 49% of infants between 0 and 2 months, and 45.5% of children between 12 and 17 months would be over-compressed during cardiopulmonary resuscitation., Conclusions: In our cohort, the 1/3 CCd targets calculated from APd measured by laser meter were shallower than the guideline-recommended CCd. Further studies including evaluating hemodynamics during cardiopulmonary resuscitation with these shallower CCd targets are needed., Competing Interests: Dr. Nadkarni received unrestricted research funding to his institution from the National Institutes of Health, Agency for Healthcare Research and Quality, ZOLL Medical Corporation, Nihon Kohden, and Volunteers on Scientific Advisory Committees for the American Heart Association, Citizen Cardiopulmonary Resuscitation (CPR) Foundation, the International Network for Simulation-based Pediatric Innovation, Research and Education (INSPIRE), and Citizen CPR; he received funding from the Society of Critical Care Medicine and the Laerdal Foundation; and he is the President of the Society of Critical Care Medicine to 2023.

Objectives: Cannulation for extracorporeal membrane oxygenation during active extracorporeal cardiopulmonary resuscitation (ECPR) is a method to rescue patients refractory to standard resuscitation. We hypothesized that early arrest hemodynamics and end-tidal C o2 (ET co2 ) are associated with survival to hospital discharge with favorable neurologic outcome in pediatric ECPR patients., Design: Preplanned, secondary analysis of pediatric Utstein, hemodynamic, and ventilatory data in ECPR patients collected during the 2016-2021 Improving Outcomes from Pediatric Cardiac Arrest study; the ICU-RESUScitation Project (ICU-RESUS; NCT02837497)., Setting: Eighteen ICUs participated in ICU-RESUS., Patients: There were 97 ECPR patients with hemodynamic waveforms during cardiopulmonary resuscitation., Interventions: None., Measurements and Main Results: Overall, 71 of 97 patients (73%) were younger than 1 year old, 82 of 97 (85%) had congenital heart disease, and 62 of 97 (64%) were postoperative cardiac surgical patients. Forty of 97 patients (41%) survived with favorable neurologic outcome. We failed to find differences in diastolic or systolic blood pressure, proportion achieving age-based target diastolic or systolic blood pressure, or chest compression rate during the initial 10 minutes of CPR between patients who survived with favorable neurologic outcome and those who did not. Thirty-five patients had ET co2 data; of 17 survivors with favorable neurologic outcome, four of 17 (24%) had an average ET co2 less than 10 mm Hg and two (12%) had a maximum ET co2 less than 10 mm Hg during the initial 10 minutes of resuscitation., Conclusions: We did not identify an association between early hemodynamics achieved by high-quality CPR and survival to hospital discharge with favorable neurologic outcome after pediatric ECPR. Candidates for ECPR with ET co2 less than 10 mm Hg may survive with favorable neurologic outcome., Competing Interests: Drs.

Objectives: Children with trisomy 21 often have anatomic and physiologic features that may complicate tracheal intubation (TI). TI in critically ill children with trisomy 21 is not well described. We hypothesize that in children with trisomy 21, TI is associated with greater odds of adverse airway outcomes (AAOs), including TI-associated events (TIAEs), and peri-intubation hypoxemia (defined as > 20% decrease in pulse oximetry saturation [Sp o2 ])., Design: Retrospective database study using the National Emergency Airway Registry for Children (NEAR4KIDS)., Setting: Registry data from 16 North American PICUs and cardiac ICUs (CICUs), from January 2014 to December 2020., Patients: A cohort of children under 18 years old who underwent TI in the PICU or CICU from in a NEAR4KIDS center. We identified patients with trisomy 21 and selected matched cohorts within the registry., Interventions: None., Measurements and Main Results: We included 8401 TIs in the registry dataset. Children with trisomy 21 accounted for 274 (3.3%) TIs. Among those with trisomy 21, 84% had congenital heart disease and 4% had atlantoaxial instability. Cervical spine protection was used in 6%. The diagnosis of trisomy 21 (vs. without) was associated with lower median weight 7.8 (interquartile range [IQR] 4.5-14.7) kg versus 10.6 (IQR 5.2-25) kg ( p < 0.001), and more higher percentage undergoing TI for oxygenation (46% vs. 32%, p < 0.001) and ventilation failure (41% vs. 35%, p = 0.04). Trisomy 21 patients had more difficult airway features (35% vs. 25%, p = 0.001), including upper airway obstruction (14% vs. 8%, p = 0.001). In addition, a greater percentage of trisomy 21 patients received atropine (34% vs. 26%, p = 0.004); and, lower percentage were intubated with video laryngoscopy (30% vs. 37%, p = 0.023). After 1:10 (trisomy 21:controls) propensity-score matching, we failed to identify an association difference in AAO rates (absolute risk difference -0.6% [95% CI -6.1 to 4.9], p = 0.822)., Conclusions: Despite differences in airway risks and TI approaches, we have not identified an association between the diagnosis of trisomy 21 and higher AAOs., Competing Interests: Drs.

Objectives: Extremes of patient body mass index are associated with difficult intubation and increased morbidity in adults. We aimed to determine the association between being underweight or obese with adverse airway outcomes, including adverse tracheal intubation (TI)-associated events (TIAEs) and/or severe peri-intubation hypoxemia (pulse oximetry oxygen saturation < 80%) in critically ill children., Design/setting: Retrospective cohort using the National Emergency Airway for Children registry dataset of 2013-2020., Patients: Critically ill children, 0 to 17 years old, undergoing TI in PICUs., Interventions: None., Measurements and Main Results: Registry data from 24,342 patients who underwent TI between 2013 and 2020 were analyzed. Patients were categorized using the Centers for Disease Control and Prevention weight-for-age chart: normal weight (5th-84th percentile) 57.1%, underweight (< 5th percentile) 27.5%, overweight (85th to < 95th percentile) 7.2%, and obese (≥ 95th percentile) 8.2%. Underweight was most common in infants (34%); obesity was most common in children older than 8 years old (15.1%). Underweight patients more often had oxygenation and ventilation failure (34.0%, 36.2%, respectively) as the indication for TI and a history of difficult airway (16.7%). Apneic oxygenation was used more often in overweight and obese patients (19.1%, 19.6%) than in underweight or normal weight patients (14.1%, 17.1%; p < 0.001). TIAEs and/or hypoxemia occurred more often in underweight (27.1%) and obese (24.3%) patients ( p < 0.001). TI in underweight children was associated with greater odds of adverse airway outcome compared with normal weight children after adjusting for potential confounders (underweight: adjusted odds ratio [aOR], 1.09; 95% CI, 1.01-1.18; p = 0.016). Both underweight and obesity were associated with hypoxemia after adjusting for covariates and site clustering (underweight: aOR, 1.11; 95% CI, 1.02-1.21; p = 0.01 and obesity: aOR, 1.22; 95% CI, 1.07-1.39; p = 0.002)., Conclusions: In underweight and obese children compared with normal weight children, procedures around the timing of TI are associated with greater odds of adverse airway events., Competing Interests: Ms. Napolitano’s, Dr. Shults’s, Dr. Nadkarni’s, and Dr. Nishisaki’s institution received funding from the Agency for Healthcare Research and Quality (R18HS024511).

Objectives: To assess associations between outcome and cardiopulmonary resuscitation (CPR) quality for in-hospital cardiac arrest (IHCA) in children with medical cardiac, surgical cardiac, or noncardiac disease., Design: Secondary analysis of a multicenter cluster randomized trial, the ICU-RESUScitation Project (NCT02837497, 2016-2021)., Setting: Eighteen PICUs., Patients: Children less than or equal to 18 years old and greater than or equal to 37 weeks postconceptual age receiving chest compressions (CC) of any duration during the study., Interventions: None., Measurements and Main Results: Of 1,100 children with IHCA, there were 273 medical cardiac (25%), 383 surgical cardiac (35%), and 444 noncardiac (40%) cases. Favorable neurologic outcome was defined as no more than moderate disability or no worsening from baseline Pediatric Cerebral Performance Category at discharge. The medical cardiac group had lower odds of survival with favorable neurologic outcomes compared with the noncardiac group (48% vs 55%; adjusted odds ratio [aOR] [95% CI], aOR 0.59 [95% CI, 0.39-0.87], p = 0.008) and surgical cardiac group (48% vs 58%; aOR 0.64 [95% CI, 0.45-0.9], p = 0.01). We failed to identify a difference in favorable outcomes between surgical cardiac and noncardiac groups. We also failed to identify differences in CC rate, CC fraction, ventilation rate, intra-arrest average target diastolic or systolic blood pressure between medical cardiac versus noncardiac, and surgical cardiac versus noncardiac groups. The surgical cardiac group had lower odds of achieving target CC depth compared to the noncardiac group (OR 0.15 [95% CI, 0.02-0.52], p = 0.001). We failed to identify a difference in the percentage of patients achieving target CC depth when comparing medical cardiac versus noncardiac groups., Conclusions: In pediatric IHCA, medical cardiac patients had lower odds of survival with favorable neurologic outcomes compared with noncardiac and surgical cardiac patients. We failed to find differences in CPR quality between medical cardiac and noncardiac patients, but there were lower odds of achieving target CC depth in surgical cardiac compared to noncardiac patients., Competing Interests: This study was funded by the following grants from the National Institute of Health National Heart, Lung and Blood Institute and Eunice Kennedy Shriver National Institute of Child Health and Human Development: R01HL131544, R01HD049934, UG1HD049981, UG1HD049983, UG1050096, UG1HD063108, UG1HD083166, UG1HD083170, UG1HD083171, and K23HL148541.

Objectives: To characterize inappropriate shock delivery during pediatric in-hospital cardiac arrest (IHCA)., Design: Retrospective cohort study., Setting: An international pediatric cardiac arrest quality improvement collaborative Pediatric Resuscitation Quality [pediRES-Q]., Patients: All IHCA events from 2015 to 2020 from the pediRES-Q Collaborative for which shock and electrocardiogram waveform data were available., Interventions: None., Measurements and Main Results: We analyzed 418 shocks delivered during 159 cardiac arrest events, with 381 shocks during 158 events at 28 sites remaining after excluding undecipherable rhythms. We classified shocks as: 1) appropriate (ventricular fibrillation [VF] or wide complex ≥ 150/min); 2) indeterminate (narrow complex ≥ 150/min or wide complex 100-149/min); or 3) inappropriate (asystole, sinus, narrow complex < 150/min, or wide complex < 100/min) based on the rhythm immediately preceding shock delivery. Of delivered shocks, 57% were delivered appropriately for VF or wide complex rhythms with a rate greater than or equal to 150/min. Thirteen percent were classified as indeterminate. Thirty percent were delivered inappropriately for asystole (6.8%), sinus (3.1%), narrow complex less than 150/min (11%), or wide complex less than 100/min (8.9%) rhythms. Eighty-eight percent of all shocks were delivered in ICUs or emergency departments, and 30% of those were delivered inappropriately., Conclusions: The rate of inappropriate shock delivery for pediatric IHCA in this international cohort is at least 30%, with 23% delivered to an organized electrical rhythm, identifying opportunity for improvement in rhythm identification training., Competing Interests: Drs.

Objectives: We sought to update our 2015 work in the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) guidelines for the diagnosis and management of pediatric acute respiratory distress syndrome (PARDS), considering new evidence and topic areas that were not previously addressed., Design: International consensus conference series involving 52 multidisciplinary international content experts in PARDS and four methodology experts from 15 countries, using consensus conference methodology, and implementation science., Setting: Not applicable., Patients: Patients with or at risk for PARDS., Interventions: None., Measurements and Main Results: Eleven subgroups conducted systematic or scoping reviews addressing 11 topic areas: 1) definition, incidence, and epidemiology; 2) pathobiology, severity, and risk stratification; 3) ventilatory support; 4) pulmonary-specific ancillary treatment; 5) nonpulmonary treatment; 6) monitoring; 7) noninvasive respiratory support; 8) extracorporeal support; 9) morbidity and long-term outcomes; 10) clinical informatics and data science; and 11) resource-limited settings. The search included MEDLINE, EMBASE, and CINAHL Complete (EBSCOhost) and was updated in March 2022. Grading of Recommendations, Assessment, Development, and Evaluation methodology was used to summarize evidence and develop the recommendations, which were discussed and voted on by all PALICC-2 experts. There were 146 recommendations and statements, including: 34 recommendations for clinical practice; 112 consensus-based statements with 18 on PARDS definition, 55 on good practice, seven on policy, and 32 on research. All recommendations and statements had agreement greater than 80%., Conclusions: PALICC-2 recommendations and consensus-based statements should facilitate the implementation and adherence to the best clinical practice in patients with PARDS.

Objectives: To provide an updated review of the literature on nonpulmonary treatments for pediatric acute respiratory distress syndrome (PARDS) from the Second Pediatric Acute Lung Injury Consensus Conference., Data Sources: MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost)., Study Selection: Searches were limited to children with PARDS or hypoxic respiratory failure focused on nonpulmonary adjunctive therapies (sedation, delirium management, neuromuscular blockade, nutrition, fluid management, transfusion, sleep management, and rehabilitation)., Data Extraction: Title/abstract review, full-text review, and data extraction using a standardized data collection form., Data Synthesis: The Grading of Recommendations Assessment, Development, and Evaluation approach was used to identify and summarize evidence and develop recommendations. Twenty-five studies were identified for full-text extraction. Five clinical practice recommendations were generated, related to neuromuscular blockade, nutrition, fluid management, and transfusion. Thirteen good practice statements were generated on the use of sedation, iatrogenic withdrawal syndrome, delirium, sleep management, rehabilitation, and additional information on neuromuscular blockade and nutrition. Three research statements were generated to promote further investigation in nonpulmonary therapies for PARDS., Conclusions: These recommendations and statements about nonpulmonary treatments in PARDS are intended to promote optimization and consistency of care for patients with PARDS and identify areas of uncertainty requiring further investigation., Competing Interests: Dr. Morrow’s institution received funding from the National Research Foundation of Southern Africa, EuroQual Group, and Society of Critical Care Medicine/Pediatric Critical Care Medicine; she received funding from the University of Cape Town.

Objectives: The COVID-19 pandemic resulted in adaptations to pediatric resuscitation systems of care. The objective of this study was to determine the temporal association between the pandemic and pediatric in-hospital cardiac arrest (IHCA) process of care metrics, cardiopulmonary resuscitation (cardiopulmonary resuscitation) quality, and patient outcomes., Design: Multicenter retrospective analysis of a dataset comprising observations of IHCA outcomes pre pandemic (March 1, 2019 to February 29, 2020) versus pandemic (March 1, 2020 to February 28, 2021)., Setting: Data source was the ICU-RESUScitation Project ("ICU-RESUS;" NCT028374497), a prospective, multicenter, cluster randomized interventional trial., Patients: Children (≤ 18 yr) who received cardiopulmonary resuscitation while admitted to the ICU and were enrolled in ICU-RESUS., Interventions: None., Measurements and Main Results: Among 429 IHCAs meeting inclusion criteria, occurrence during the pandemic period was associated with higher frequency of hypotension as the immediate cause of arrest. Cardiac arrest physiology, cardiopulmonary resuscitation quality metrics, and postarrest physiologic and quality of care metrics were similar between the two periods. Survival with favorable neurologic outcome (Pediatric Cerebral Performance Category score 1-3 or unchanged from baseline) occurred in 102 of 195 subjects (52%) during the pandemic compared with 140 of 234 (60%) pre pandemic ( p = 0.12). Among survivors, occurrence of IHCA during the pandemic period was associated with a greater increase in Functional Status Scale (FSS) (i.e., worsening) from baseline (1 [0-3] vs 0 [0-2]; p = 0.01). After adjustment for confounders, IHCA survival during the pandemic period was associated with a greater increase in FSS from baseline (+1.19 [95% CI, 0.35-2.04] FSS points; p = 0.006) and higher odds of a new FSS-defined morbidity (adjusted odds ratio, 1.88 [95% CI, 1.03-3.46]; p = 0.04)., Conclusions: Using the ICU-RESUS dataset, we found that relative to the year prior, pediatric IHCA during the first year of the COVID-19 pandemic was associated with greater worsening of functional status and higher odds of new functional morbidity among survivors., Competing Interests: Drs.

Objectives: Pediatric Advanced Life Support (PALS) guidelines include weight-based epinephrine dosing recommendations of 0.01 mg/kg with a maximum of 1 mg, which corresponds to a weight of 100 kg. Actual practice patterns are unknown., Design: Multicenter cross-sectional survey regarding institutional practices for the transition from weight-based to flat dosing of epinephrine during cardiopulmonary resuscitation in PICUs. Exploratory analyses compared epinephrine dosing practices with several institutional characteristics using Fisher exact test., Setting: Internet-based survey., Subjects: U.S. PICU representatives (one per institution) involved in resuscitation systems of care., Interventions: None., Measurements and Main Results: Of 137 institutions surveyed, 68 (50%) responded. Most responding institutions are freestanding children's hospitals or dedicated children's hospitals within combined adult/pediatric hospitals (67; 99%); 55 (81%) are academic and 41 (60%) have PICU fellowship programs. Among respondents, institutional roles include PICU medical director (13; 19%), resuscitation committee member (23; 34%), and attending physician with interest in resuscitation (21; 31%). When choosing between weight-based and flat dosing, 64 respondents (94%) report using patient weight, 23 (34%) patient age, and five (7%) patient pubertal stage. Among those reporting using weight, 28 (44%) switch at 50 to less than 60 kg, 17 (27%) at 60 to less than 80 kg, five (8%) at 80 to less than 100 kg, and eight (12%) at greater than or equal to 100 kg. Among those reporting using age, four (17%) switch at 14 to less than 16 years, five (22%) at 16 to less than 18, and six (26%) at greater than or equal to 18. Twenty-nine respondents (43%) report using ideal body weight when dosing epinephrine in obese patients. Using patient age in choosing epinephrine dosing is more common in institutions that require Advanced Cardiac Life Support (ACLS) certification for some/all code team responders compared with institutions that do not require ACLS certification (52% vs 22%; p = 0.02)., Conclusions: The majority of PICUs surveyed report epinephrine dosing practices that are inconsistent with PALS guidelines., Competing Interests: Dr. Morgan’s institution received funding from the National Heart, Lung, and Blood Institute (K23HL148541).

Objectives: To evaluate associations between sodium bicarbonate use and outcomes during pediatric in-hospital cardiac arrest (p-IHCA)., Design: Prespecified secondary analysis of a prospective, multicenter cluster randomized interventional trial., Setting: Eighteen participating ICUs of the ICU-RESUScitation Project (NCT02837497)., Patients: Children less than or equal to 18 years old and greater than or equal to 37 weeks post conceptual age who received chest compressions of any duration from October 2016 to March 2021., Interventions: None., Measurements and Main Results: Child and event characteristics, prearrest laboratory values (2-6 hr prior to p-IHCA), pre- and intraarrest hemodynamics, and outcomes were collected. In a propensity score weighted cohort, the relationships between sodium bicarbonate use and outcomes were assessed. The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation (ROSC) and survival to hospital discharge with favorable neurologic outcome. Of 1,100 index cardiopulmonary resuscitation events, median age was 0.63 years (interquartile range, 0.19-3.81 yr); 528 (48.0%) received sodium bicarbonate; 773 (70.3%) achieved ROSC; 642 (58.4%) survived to hospital discharge; and 596 (54.2%) survived to hospital discharge with favorable neurologic outcome. Among the weighted cohort, sodium bicarbonate use was associated with lower survival to hospital discharge rate (adjusted odds ratio [aOR], 0.7; 95% CI, 0.54-0.92; p = 0.01) and lower survival to hospital discharge with favorable neurologic outcome rate (aOR, 0.69; 95% CI, 0.53-0.91; p = 0.007). Sodium bicarbonate use was not associated with ROSC (aOR, 0.91; 95% CI, 0.62-1.34; p = 0.621)., Conclusions: In this propensity weighted multicenter cohort study of p-IHCA, sodium bicarbonate use was common and associated with lower rates of survival to hospital discharge., Competing Interests: Drs.

Objectives: To compare outcomes associated with timing-early versus late-of any neurologic dysfunction during pediatric sepsis., Design: Secondary analysis of a cross-sectional point prevalence study., Setting: A total of 128 PICUs in 26 countries., Patients: Less than 18 years with severe sepsis on 5 separate days (2013-2014)., Interventions: None., Measurements and Main Results: Patients were categorized as having either no neurologic dysfunction or neurologic dysfunction (i.e., present at or after sepsis recognition), which was defined as Glasgow Coma Scale score less than 5 and/or fixed dilated pupils. Our primary outcome was death or new moderate disability (i.e., Pediatric Overall [or Cerebral] Performance Category score ≥3 and change ≥1 from baseline) at hospital discharge, and 87 of 567 severe sepsis patients (15%) had neurologic dysfunction within 7 days of sepsis recognition (61 at sepsis recognition and 26 after sepsis recognition). Primary site of infection varied based on presence of neurologic dysfunction. Death or new moderate disability occurred in 161 of 480 (34%) without neurologic dysfunction, 45 of 61 (74%) with neurologic dysfunction at sepsis recognition, and 21 of 26 (81%) with neurologic dysfunction after sepsis recognition (p < 0.001 across all groups). On multivariable analysis, in comparison with those without neurologic dysfunction, neurologic dysfunction whether at sepsis recognition or after was associated with increased odds of death or new moderate disability (adjusted odds ratio, 4.9 [95% CI, 2.3-10.1] and 10.7 [95% CI, 3.8-30.5], respectively). We failed to identify a difference between these adjusted odds ratios of death or new moderate disability that would indicate a differential risk of outcome based on timing of neurologic dysfunction (p = 0.20)., Conclusions: In this severe sepsis international cohort, the presence of neurologic dysfunction during sepsis is associated with worse outcomes at hospital discharge. The impact of early versus late onset of neurologic dysfunction in sepsis on outcome remains unknown, and further work is needed to better understand timing of neurologic dysfunction onset in pediatric sepsis., Competing Interests: Drs.

Objectives: To use improved situation awareness to decrease cardiopulmonary resuscitation events by 25% over 18 months and demonstrate process and outcome sustainability., Design: Structured quality improvement initiative., Setting: Single-center, 35-bed quaternary-care PICU., Patients: All patients admitted to the PICU from February 1, 2017, to December 31, 2020., Interventions: Interventions targeted situation awareness and included bid safety huddles, bedside mitigation signs and huddles, smaller pod-based huddles, and an automated clinical decision support tool to identify high-risk patients., Measurements and Main Results: The primary outcome metric, cardiopulmonary resuscitation event rate per 1,000 patient-days, decreased from a baseline of 3.1-1.5 cardiopulmonary resuscitation events per 1,000 patient-days or by 52%. The secondary outcome metric, mortality rate, decreased from a baseline of 6.6 deaths per 1,000 patient-days to 3.6 deaths per 1,000 patient-days. Process metrics included percent of clinical deterioration events predicted, which increased from 40% to 67%, and percent of high-risk patients with shared situation awareness, which increased from 43% to 71%. Balancing metrics included time spent in daily safety huddle, median 0.4 minutes per patient (interquartile range, 0.3-0.5), and a number needed to alert of 16 (95% CI, 14-25). Neither unit acuity as measured by Pediatric Risk of Mortality III scores nor the percent of deaths in patients with do-not-attempt resuscitation orders or electing withdrawal of life-sustaining technologies changed over time., Conclusions: Interprofessional teams using shared situation awareness may reduce cardiopulmonary resuscitation events and, thereby, improve outcomes., Competing Interests: Dr. Dewan receives career development support from the Agency for Healthcare Research and Quality (AHRQ) (K08-HS026975) and received support for article research from the National Institutes of Health (NIH).

Objectives: We developed a tool, Serial Neurologic Assessment in Pediatrics, to screen for neurologic changes in patients, including those who are intubated, are sedated, and/or have developmental disabilities. Our aims were to: 1) determine protocol adherence when performing Serial Neurologic Assessment in Pediatrics, 2) determine the interrater reliability between nurses, and 3) assess the feasibility and acceptability of using Serial Neurologic Assessment in Pediatrics compared with the Glasgow Coma Scale., Design: Mixed-methods, observational cohort., Setting: Pediatric and neonatal ICUs., Subjects: Critical care nurses and patients., Interventions: None., Measurements and Main Results: Serial Neurologic Assessment in Pediatrics assesses Mental Status, Cranial Nerves, Communication, and Motor Function, with scales for children less than 6 months, greater than or equal to 6 months to less than 2 years, and greater than or equal to 2 years old. We assessed protocol adherence with standardized observations. We assessed the interrater reliability of independent Serial Neurologic Assessment in Pediatrics assessments between pairs of trained nurses by percent- and bias- adjusted kappa and percent agreement. Semistructured interviews with nurses evaluated acceptability and feasibility after nurses used Serial Neurologic Assessment in Pediatrics concurrently with Glasgow Coma Scale during routine care. Ninety-eight percent of nurses (43/44) had 100% protocol adherence on the standardized checklist. Forty-three nurses performed 387 paired Serial Neurologic Assessment in Pediatrics assessments (149 < 6 mo; 91 ≥ 6 mo to < 2 yr, and 147 ≥ 2 yr) on 299 patients. Interrater reliability was substantial to near-perfect across all components for each age-based Serial Neurologic Assessment in Pediatrics scale. Percent agreement was independent of developmental disabilities for all Serial Neurologic Assessment in Pediatrics components except Mental Status and lower extremity Motor Function for patients deemed "Able to Participate" with the assessment. Nurses reported that they felt Serial Neurologic Assessment in Pediatrics, compared with Glasgow Coma Scale, was easier to use and clearer in describing the neurologic status of patients who were intubated, were sedated, and/or had developmental disabilities. About 92% of nurses preferred to use Serial Neurologic Assessment in Pediatrics over Glasgow Coma Scale., Conclusions: When used by critical care nurses, Serial Neurologic Assessment in Pediatrics has excellent protocol adherence, substantial to near-perfect interrater reliability, and is feasible to implement. Further work will determine the sensitivity and specificity for detecting clinically meaningful neurologic decline., Competing Interests: Drs.

Objectives: To determine timing and cause of death in children admitted to the PICU following return of circulation after out-of-hospital cardiac arrest., Design: Retrospective observational study., Setting: Single-center observational cohort study at the PICU of a tertiary-care hospital (Erasmus MC-Sophia, Rotterdam, The Netherlands) between 2012 and 2017., Patients: Children younger than 18 years old with out-of-hospital cardiac arrest and return of circulation admitted to the PICU., Measurements and Results: Data included general, cardiopulmonary resuscitation and postreturn of circulation characteristics. The primary outcome was defined as survival to hospital discharge. Modes of death were classified as brain death, withdrawal of life-sustaining therapies due to poor neurologic prognosis, withdrawal of life-sustaining therapies due to refractory circulatory and/or respiratory failure, and recurrent cardiac arrest without return of circulation. One hundred thirteen children with out-of-hospital cardiac arrest were admitted to the PICU following return of circulation (median age 53 months, 64% male, most common cause of out-of-hospital cardiac arrest drowning [21%]). In these 113 children, there was 44% survival to hospital discharge and 56% nonsurvival to hospital discharge (brain death 29%, withdrawal of life-sustaining therapies due to poor neurologic prognosis 67%, withdrawal of life-sustaining therapies due to refractory circulatory and/or respiratory failure 2%, and recurrent cardiac arrest 2%). Compared with nonsurvivors, more survivors had witnessed arrest (p = 0.007), initial shockable rhythm (p < 0.001), shorter cardiopulmonary resuscitation duration (p < 0.001), and more favorable clinical neurologic examination within 24 hours after admission. Basic cardiopulmonary resuscitation event and postreturn of circulation (except for the number of extracorporeal membrane oxygenation) characteristics did not significantly differ between the withdrawal of life-sustaining therapies due to poor neurologic prognosis and brain death patients. Timing of decision-making to withdrawal of life-sustaining therapies due to poor neurologic prognosis ranged from 0 to 18 days (median: 0 d; interquartile range, 0-3) after cardiopulmonary resuscitation. The decision to withdrawal of life-sustaining therapies was based on neurologic examination (100%), electroencephalography (44%), and/or brain imaging (35%)., Conclusions: More than half of children who achieve return of circulation after out-of-hospital cardiac arrest died after PICU admission. Of these deaths, two thirds (67%) underwent withdrawal of life-sustaining therapies based on an expected poor neurologic prognosis and did so early after return of circulation. There is a need for international guidelines for accurate neuroprognostication in children after cardiac arrest., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2020 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.)

Objectives: The Heart And Lung Failure-Pediatric INsulin Titration study was experiencing poor subject enrollment due to low rates of informed consent. Heart And Lung Failure-Pediatric INsulin Titration investigators collaborated with the Perelman School of Medicine Standardized Patient Program to explore the novel use of telesimulation with standardized parents to train research staff to approach parents of critically ill children for informed consent. We describe the feasibility, learner acceptance, and financial costs of this novel intervention and performed a post hoc analysis to determine if this intervention improved study consent rates., Design: Observational, comparative effectiveness study., Setting: Heart And Lung Failure-Pediatric INsulin Titration study enrolling sites., Subjects: Research staff (at the remote site)., Interventions: Individual 90-minute Skype telesimulation sessions with standardized parent and simulation facilitator (at the training site)., Measurements and Main Results: Forty telesimulation sessions with 79 Heart And Lung Failure-Pediatric INsulin Titration research staff (participants) at 24 remote sites were conducted. Despite some technical delays, 40 out of 40 simulations (100%) were completed. Based on feedback surveys, 100% of respondents agreed (81% strongly agreed) that telesimulation sessions achieved intended learning objectives to prepare research staff to approach parents of eligible critically ill children to obtain informed consent. Additionally, 100% of respondents agreed (74% strongly agreed) that they would use lessons from the telesimulation when approaching parents to obtain informed consent for research. Telesimulation with standardized parents achieved lower financial costs (approximately $85 per session) compared with traditional in-person site visits for training research staff. There was no significant improvement in study consent rates with the intervention (pre: 46% vs post: 48%; p = 0.78)., Conclusions: Remote telesimulation with standardized parents is feasible, acceptable, and associated with lower financial costs to prepare research staff to obtain informed consent from parents of critically ill children eligible for clinical research trials. Despite this novel approach, Heart And Lung Failure-Pediatric INsulin Titration study consent rates did not improve, suggesting that other factors influence parental consent and decision making in complex multicenter clinical research trials.

Objectives: Tracheal intubation carries a high risk of adverse events. The current literature is unclear regarding the "New Trainee Effect" on tracheal intubation safety in the PICU. We evaluated the effect of the timing of the PICU fellow academic cycle on tracheal intubation associated events. We hypothesize 1) PICUs with pediatric critical care medicine fellowship programs have more adverse tracheal intubation associated events during the first quarter (July-September) of the academic year compared with the rest of the year and 2) tracheal intubation associated event rates and first attempt success performed by pediatric critical care medicine fellows improve through the 3-year clinical fellowship., Design: Retrospective cohort study., Setting: Thirty-seven North American PICUs participating in National Emergency Airway Registry for Children., Patients: All patients who underwent tracheal intubations in the PICU from July 2013 to June 2017., Interventions: None., Measurements and Main Results: The occurrence of any tracheal intubation associated events during the first quarter of the academic year (July-September) was compared with the rest in four different types of PICUs: PICUs with fellows and residents, PICUs with fellows only, PICUs with residents only, and PICUs without trainees. For the second hypothesis, tracheal intubations by critical care medicine fellows were categorized by training level and quarter for 3 years of fellowship (i.e., July-September of 1st yr pediatric critical care medicine fellowship = first quarter, October-December of 1st yr pediatric critical care medicine fellowship = second quarter, and April-June during 3rd year = 12th quarter). A total of 9,774 tracheal intubations were reported. Seven-thousand forty-seven tracheal intubations (72%) were from PICUs with fellows and residents, 525 (5%) with fellows only, 1,201 (12%) with residents only, and 1,001 (10%) with no trainees. There was no difference in the occurrence of tracheal intubation associated events in the first quarter versus the rest of the year (all PICUs: July-September 14.9% vs October-June 15.2%; p = 0.76). There was no difference between these two periods in each type of PICUs (all p ≥ 0.19). For tracheal intubations by critical care medicine fellows (n = 3,836), tracheal intubation associated events significantly decreased over the fellowship: second quarter odds ratio 0.64 (95% CI, 0.45-0.91), third quarter odds ratio 0.58 (95% CI, 0.42-0.82), and 12th quarter odds ratio 0.40 (95% CI, 0.24-0.67) using the first quarter as reference after adjusting for patient and device characteristics. First attempt success significantly improved during fellowship: second quarter odds ratio 1.39 (95% CI, 1.04-1.85), third quarter odds ratio 1.59 (95% CI, 1.20-2.09), and 12th quarter odds ratio 2.11 (95% CI, 1.42-3.14)., Conclusions: The New Trainee Effect in tracheal intubation safety outcomes was not observed in various types of PICUs. There was a significant improvement in pediatric critical care medicine fellows' first attempt success and a significant decline in tracheal intubation associated event rates, indicating substantial skills acquisition throughout pediatric critical care medicine fellowship.

Objectives: Determine level of agreement among clinical signs of shock type, identify which signs clinicians prioritize to determine shock type and select vasoactive medications, and test the association of shock type-vasoactive mismatch with prolonged organ dysfunction or death (complicated course)., Design: Retrospective observational study., Setting: Single large academic PICU., Patients: Patients less than 18 years treated on a critical care sepsis pathway between 2012 and 2016., Interventions: None., Measurements and Main Results: Agreement among clinical signs (extremity temperature, capillary refill, pulse strength, pulse pressure, and diastolic blood pressure) was measured using Fleiss and Cohen's κ. Association of clinical signs with shock type and shock type-vasoactive mismatch (e.g., cold shock treated with vasopressor rather than inotrope) with complicated course was determined using multivariable logistic regression. Of 469 patients, clinicians determined 307 (65%) had warm and 162 (35%) had cold shock. Agreement across all clinical signs was low (κ, 0.25; 95% CI, 0.20-0.30), although agreement between extremity temperature, capillary refill, and pulse strength was better than with pulse pressure and diastolic blood pressure. Only extremity temperature (adjusted odds ratio, 26.6; 95% CI, 15.5-45.8), capillary refill (adjusted odds ratio, 15.7; 95% CI, 7.9-31.3), and pulse strength (adjusted odds ratio, 21.3; 95% CI, 8.6-52.7) were associated with clinician-documented shock type. Of the 86 patients initiated on vasoactive medications during the pathway, shock type was discordant from vasoactive medication (κ, 0.14; 95% CI, -0.03 to 0.31) and shock type-vasoactive mismatch was not associated with complicated course (adjusted odds ratio, 0.3; 95% CI, 0.1-1.02)., Conclusions: Agreement was low among common clinical signs used to characterize shock type, with clinicians prioritizing extremity temperature, capillary refill, and pulse strength. Although clinician-assigned shock type was often discordant with vasoactive choice, shock type-vasoactive mismatch was not associated with complicated course. Categorizing shock based on clinical signs should be done cautiously.

Objectives: To develop a consensus framework that can guide the process of classifying and reviewing pediatric in-hospital cardiac arrest in the PICU., Design: A three-round electronic Delphi consensus study with an additional in-person session with pediatric resuscitation experts. The modified electronic Delphi consisted of survey questions sent to the expert panel with the goals of (1) achieving consensus on definitions of avoidable, potentially avoidable, and unavoidable PICU in-hospital cardiac arrest and (2) achieving consensus and ranking of a list of factors that contribute to potentially avoidable PICU in-hospital cardiac arrest., Setting: Electronic surveys of resuscitation experts including pediatric critical care, cardiac critical care, emergency medicine, and hospital medicine physicians, nurses, advance practice nurses, and resuscitation researchers., Patients: Not applicable., Interventions: Not applicable., Measurements and Main Results: Over three rounds of an electronic Delphi, 24 resuscitation experts participated. In Round 1, consensus was reached for the definitions of potentially avoidable and unavoidable cardiac arrest. Consensus was not reached for avoidable cardiac arrest. In Round 2, the expert panel agreed with seven factors from the literature and achieved consensus on an additional seven factors. Consensus was achieved on the modified definition of avoidable cardiac arrest. In Round 3, participants were asked to rank the contributing factors in order of their importance. For the in-person session, the consensus definitions and contributing factors from the modified electronic Delphi were presented to a multidisciplinary group of pediatric resuscitation experts and reached consensus for all three definitions., Conclusions: A multidisciplinary group of pediatric resuscitation experts generated a consensus-based framework to classify and review pediatric in-hospital cardiac arrest in the PICU. Future work will focus on the application of this framework and further validation of these definitions and contributing factors for in-hospital cardiac arrest both within and outside the PICU.

Objectives: Postcardiac arrest care bundles following adult cardiac arrest are associated with improved survival to discharge. We aimed to evaluate whether a clinical pathway and computerized order entry were associated with improved pediatric postcardiac arrest care and discharge outcomes., Design: Single-center retrospective before-after study., Setting: Academic PICU., Patients: Patients who suffered an in- or out-of-hospital cardiac arrest from January 2008 to December 2015 cared for in the PICU within 12 hours of sustained return of circulation., Intervention: Deployment of a postcardiac arrest clinical pathway and computerized order entry system., Measurements and Main Results: There were 380 patients included-163 in the pre-pathway period and 217 in the post-pathway period. Primary outcome was percent adherence to pathway clinical goals at 0-6 and 6-24 hours post-return of circulation and to diagnostics (continuous electroencephalogram monitoring, head CT for out-of-hospital cardiac arrests, echocardiogram). Secondary outcomes included survival to hospital discharge and survival with favorable neurologic outcome (Pediatric Cerebral Performance Category of 1-3 or no change from baseline). The pre-pathway and post-pathway groups differed in their baseline Pediatric Cerebral Performance Category scores and the following causes of arrest: airway obstruction, arrhythmias, and electrolyte abnormalities. Pathway adherence was not significantly different between the pre-pathway and post-pathway groups, with the exception of higher rates of continuous electroencephalogram monitoring (45% vs 64%; p < 0.001). There was no difference in survival to hospital discharge between the two groups (56% vs 67%; adjusted odds ratio, 1.68; 95% CI, 0.95-2.84; p = 0.05). Survival to discharge was higher in the post-pathway group for the in-hospital cardiac arrest cohort (55% vs 76%; adjusted odds ratio, 3.06; 95% CI, 1.44-6.51; p < 0.01). There was no difference in favorable neurologic outcome between all patients (adjusted odds ratio, 1.21; 95% CI, 0.72-2.04) or among survivors (adjusted odds ratio, 0.72; 95% CI, 0.27-1.43)., Conclusions: After controlling for known potential confounders, the creation and deployment of a postcardiac arrest care pathway and computerized order entry set were not associated with improvement in pathway adherence or overall outcomes, but was associated with increased survival to hospital discharge for children with in-hospital cardiac arrests.

Objectives: While most pediatric coronavirus disease 2019 cases are not life threatening, some children have severe disease requiring emergent resuscitative interventions. Resuscitation events present risks to healthcare provider safety and the potential for compromised patient care. Current resuscitation practices and policies for children with suspected/confirmed coronavirus disease 2019 are unknown., Design: Multi-institutional survey regarding inpatient resuscitation practices during the coronavirus disease 2019 pandemic., Setting: Internet-based survey., Subjects: U.S. PICU representatives (one per institution) involved in resuscitation system planning and oversight., Interventions: None., Measurements and Main Results: Of 130 institutions surveyed, 78 (60%) responded. Forty-eight centers (62%) had admitted coronavirus disease 2019 patients; 26 (33%) reported code team activation for patients with suspected/confirmed coronavirus disease 2019. Sixty-seven respondents (86%) implemented changes to inpatient emergency response systems. The most common changes were as follows: limited number of personnel entering patient rooms (75; 96%), limited resident involvement (71; 91%), and new or refined team roles (74; 95%). New or adapted technology is being used for coronavirus disease 2019 resuscitations in 58 centers (74%). Most institutions (57; 73%) are using enhanced personal protective equipment for all coronavirus disease 2019 resuscitation events; 18 (23%) have personal protective equipment policies dependent on the performance of aerosol generating procedures. Due to coronavirus disease 2019, most respondents are intubating earlier during cardiopulmonary resuscitation (56; 72%), utilizing video laryngoscopy (67; 86%), pausing chest compressions during laryngoscopy (56; 72%), and leaving patients connected to the ventilator during cardiopulmonary resuscitation (56; 72%). Responses were varied regarding airway personnel, prone cardiopulmonary resuscitation, ventilation strategy during cardiopulmonary resuscitation without an airway in place, and extracorporeal cardiopulmonary resuscitation. Most institutions (46; 59%) do not have policies regarding limitations of resuscitation efforts in coronavirus disease 2019 patients., Conclusions: Most U.S. pediatric institutions rapidly adapted their resuscitation systems and practices in response to the coronavirus disease 2019 pandemic. Changes were commonly related to team members and roles, personal protective equipment, and airway and breathing management, reflecting attempts to balance quality resuscitation with healthcare provider safety.

Objectives: The coronavirus disease 2019 pandemic has required that hospitals rapidly adapt workflows and processes to limit disease spread and optimize the care of critically ill children., Design and Setting: As part of our institution's coronavirus disease 2019 critical care workflow design process, we developed and conducted a number of simulation exercises, increasing in complexity, progressing to intubation wearing personal protective equipment, and culminating in activation of our difficult airway team for an airway emergency., Patients and Interventions: In situ simulations were used to identify and rework potential failure points to generate guidance for optimal airway management in coronavirus disease 2019 suspected or positive children. Subsequent to this high-realism difficult airway simulation was a real-life difficult airway event in a patient suspected of coronavirus disease 2019 less than 12 hours later, validating potential failure points and effectiveness of rapidly generated guidance., Measurements and Main Results: A number of potential workflow challenges were identified during tabletop and physical in situ manikin-based simulations. Experienced clinicians served as participants, debriefed, and provided feedback that was incorporated into local site clinical pathways, job aids, and suggested practices. Clinical management of an actual suspected coronavirus disease 2019 patient with difficult airway demonstrated very similar success and anticipated failure points. Following debriefing and assembly of a success/failure grid, a coronavirus disease 2019 airway bundle template was created using these simulations and clinical experiences for others to adapt to their sites., Conclusions: Integration of tabletop planning, in situ simulations, and debriefing of real coronavirus disease 2019 cases can enhance planning, training, job aids, and feasible policies/procedures that address human factors, team communication, equipment choice, and patient/provider safety in the coronavirus disease 2019 pandemic era.

Objectives: The impact of early enteral nutrition on clinical outcomes in critically ill children has not been adequately described. We hypothesized that early enteral nutrition is associated with improved clinical outcomes in critically ill children., Design: Secondary analysis of the Heart and Lung Failure-Pediatric Insulin Titration randomized controlled trial., Setting: Thirty-five PICUs., Patients: Critically ill children with hyperglycemia requiring inotropic support and/or invasive mechanical ventilation who were enrolled for at least 48 hours with complete nutrition data., Interventions: Subjects received nutrition via guidelines that emphasized enteral nutrition and were classified into early enteral nutrition (enteral nutrition within 48 hr of study randomization) and no early enteral nutrition (enteral nutrition after 48 hr of study randomization, or no enteral nutrition at any time)., Measurements and Main Results: Of 608 eligible subjects, 331 (54%) received early enteral nutrition. Both early enteral nutrition and no early enteral nutrition groups had similar daily caloric intake over the first 8 study days (median, 36 vs 36 kcal/kg/d; p = 0.93). After controlling for age, body mass index z scores, primary reason for ICU admission, severity of illness, and mean Vasopressor-Inotrope Score at the time of randomization, and adjusting for site, early enteral nutrition was associated with lower 90-day hospital mortality (8% vs 17%; p = 0.007), more ICU-free days (median, 20 vs 17 d; p = 0.02), more hospital-free days (median, 8 vs 0 d; p = 0.003), more ventilator-free days (median, 21 vs 19 d; p = 0.003), and less organ dysfunction (median maximum Pediatric Logistic Organ Dysfunction, 11 vs 12; p < 0.001)., Conclusions: In critically ill children with hyperglycemia requiring inotropic support and/or mechanical ventilation, early enteral nutrition was independently associated with better clinical outcomes.

Objectives: To evaluate the translation of a paper high-risk checklist for PICU patients at risk of clinical deterioration to an automated clinical decision support tool., Design: Retrospective, observational cohort study of an automated clinical decision support tool, the PICU Warning Tool, adapted from a paper checklist to predict clinical deterioration events in PICU patients within 24 hours., Setting: Two quaternary care medical-surgical PICUs-The Children's Hospital of Philadelphia and Cincinnati Children's Hospital Medical Center., Patients: The study included all patients admitted from July 1, 2014, to June 30, 2015, the year prior to the initiation of any focused situational awareness work at either institution., Interventions: We replicated the predictions of the real-time PICU Warning Tool by retrospectively querying the institutional data warehouse to identify all patients that would have flagged as high-risk by the PICU Warning Tool for their index deterioration., Measurements and Main Results: The primary exposure of interest was determination of high-risk status during PICU admission via the PICU Warning Tool. The primary outcome of interest was clinical deterioration event within 24 hours of a positive screen. The date and time of the deterioration event was used as the index time point. We evaluated the sensitivity, specificity, positive predictive value, and negative predictive value of the performance of the PICU Warning Tool. There were 6,233 patients evaluated with 233 clinical deterioration events experienced by 154 individual patients. The positive predictive value of the PICU Warning Tool was 7.1% with a number needed to screen of 14 patients for each index clinical deterioration event. The most predictive of the individual criteria were elevated lactic acidosis, high mean airway pressure, and profound acidosis., Conclusions: Performance of a clinical decision support translation of a paper-based tool showed inferior test characteristics. Improved feasibility of identification of high-risk patients using automated tools must be balanced with performance.

Objectives: To evaluate the association of a single episode of hypotension and burden of hypotension with survival to hospital discharge following resuscitation from pediatric cardiac arrest., Design: Retrospective cohort study., Setting: Single-center PICU., Patients: Patients between 1 day and 18 years old who had a cardiac arrest, received chest compressions for more than 2 minutes, had return of spontaneous circulation for more than 20 minutes, and survived to receive postresuscitation care in the ICU., Interventions: None., Measurement and Main Results: One-hundred sixteen patients were evaluable. Hypotension, defined as systolic blood pressure less than the fifth percentile for age and sex, occurred in 37 patients (32%) within the first 6 hours and 64 (55%) within 72 hours of postresuscitation ICU care. There was no significant difference in survival to discharge for patients who had a single episode of hypotension within 6 hours (51% vs 69%; p = 0.06) or within 72 hours (56% vs 73%; p = 0.06). Burden of hypotension was defined as the percentage of hypotension measurements that were below the fifth percentile. After controlling for patient and cardiac arrest event characteristics, a higher burden of hypotension within the first 72 hours of ICU postresuscitation care was associated with decreased discharge survival (adjusted odds ratio = 0.67 per 10% increase in hypotension burden; 95% CI, 0.48-0.86; p = 0.006)., Conclusions: After successful resuscitation from pediatric cardiac arrest, systolic hypotension was common (55%). A higher burden of postresuscitation hypotension within the first 72 hours of ICU postresuscitation care was associated with significantly decreased discharge survival, after accounting for potential confounders including number of doses of epinephrine, arrest location, and arrest etiology due to airway obstruction or trauma.

Objectives: To evaluate if the use of apneic oxygenation during tracheal intubation in children is feasible and would decrease the occurrence of oxygen desaturation., Design: Prospective pre/post observational study., Setting: A large single-center noncardiac PICU in North America., Patients: All patients less than 18 years old who underwent primary tracheal intubation from August 1, 2014, to September 30, 2018., Interventions: Implementation of apneic oxygenation for all primary tracheal intubation as quality improvement., Measurements and Main Results: Total of 1,373 tracheal intubations (661 preimplementation and 712 postimplementation) took place during study period. Within 2 months, apneic oxygenation use reached to predefined adherence threshold (> 80% of primary tracheal intubations) after implementation and sustained at greater than 70% level throughout the postimplementation. Between the preimplementation and postimplementation, no significant differences were observed in patient demographics, difficult airway features, or providers. Respiratory and procedural indications were more common during preintervention. Video laryngoscopy devices were used more often during the postimplementation (pre 5% vs post 75%; p < 0.001). Moderate oxygen desaturation less than 80% were observed in fewer tracheal intubations after apneic oxygenation implementation (pre 15.4% vs post 11.8%; p = 0.049); severe oxygen desaturation less than 70% was also observed in fewer tracheal intubations after implementation (pre 10.4% vs post 7.2%; p = 0.032). Hemodynamic tracheal intubation associated events (i.e., cardiac arrests, hypotension, dysrhythmia) were unchanged (pre 3.2% vs post 2.0%; p = 0.155). Multivariable analyses showed apneic oxygenation implementation was significantly associated with a decrease in moderate desaturation less than 80% (adjusted odds ratio, 0.55; 95% CI, 0.34-0.88) and with severe desaturation less than 70% (adjusted odds ratio, 0.54; 95% CI, 0.31-0.96) while adjusting for tracheal intubation indications and device., Conclusions: Implementation of apneic oxygenation in PICU was feasible, and was associated with significant reduction in moderate and severe oxygen desaturation. Use of apneic oxygenation should be considered when intubating critically ill children.

Objectives: Patterns and outcomes of multiple organ dysfunction syndrome are unknown in critically ill children with hyperglycemia. We aimed to determine whether tight glycemic control to a lower vs. higher range influenced timing, duration, or resolution of multiple organ dysfunction syndrome as well as characterize the clinical outcomes of subgroups of multiple organ dysfunction syndrome in children enrolled in the Heart And Lung Failure-Pediatric INsulin Titration trial., Design: Planned secondary analysis of the multicenter Heart And Lung Failure-Pediatric INsulin Titration trial., Setting: Thirty-five PICUs., Patients: Critically ill children with hyperglycemia who received the Heart And Lung Failure-Pediatric INsulin Titration protocol from 2012 to 2016., Interventions: Randomization to a lower versus higher glucose target group., Measurements and Main Results: Of 698 patients analyzed, 48 (7%) never developed multiple organ dysfunction syndrome, 549 (79%) had multiple organ dysfunction syndrome without progression, 32 (5%) developed new multiple organ dysfunction syndrome, and 69 (10%) developed progressive multiple organ dysfunction syndrome. Of those whose multiple organ dysfunction syndrome resolved, 192 (34%) experienced recurrent multiple organ dysfunction syndrome. There were no significant differences in the proportion of multiple organ dysfunction syndrome subgroups between Heart And Lung Failure-Pediatric INsulin Titration glucose target groups. However, patients with new or progressive multiple organ dys function syndrome had fewer ICU-free days through day 28 than those without new or progressive multiple organ dysfunction syndrome, and progressive multiple organ dysfunction syndrome patients had fewer ICU-free days than those with new multiple organ dysfunction syndrome: median 25.1 days for never multiple organ dysfunction syndrome, 20.2 days for multiple organ dysfunction syndrome without progression, 18.6 days for new multiple organ dysfunction syndrome, and 0 days for progressive multiple organ dysfunction syndrome (all comparisons p < 0.001). Patients with recurrent multiple organ dysfunction syndrome experienced fewer ICU-free days than those without recurrence (median, 11.2 vs 22.8 d; p < 0.001)., Conclusions: Tight glycemic control target range was not associated with differences in the proportion of new, progressive, or recurrent multiple organ dysfunction syndrome. New or progressive multiple organ dysfunction syndrome was associated with poor clinical outcomes, and progressive multiple organ dysfunction syndrome was associated with worse outcomes than new multiple organ dysfunction syndrome. In future studies, new multiple organ dysfunction syndrome and progressive multiple organ dysfunction syndrome may need to be considered separately, as they represent distinct subgroups with different, potentially modifiable risk factors. Patients with recurrent multiple organ dysfunction syndrome represent a newly characterized, high-risk group which warrants attention in future research.

Objectives: To assess the association of diastolic blood pressure cutoffs (≥ 25 mm Hg in infants and ≥ 30 mm Hg in children) during cardiopulmonary resuscitation with return of spontaneous circulation and survival in surgical cardiac versus medical cardiac patients. Secondarily, we assessed whether these diastolic blood pressure targets were feasible to achieve and associated with outcome in physiology unique to congenital heart disease (single ventricle infants, open chest), and influenced outcomes when extracorporeal cardiopulmonary resuscitation was deployed., Design: Multicenter, prospective, observational cohort analysis., Setting: Tertiary PICU and cardiac ICUs within the Collaborative Pediatric Critical Care Research Network., Patients: Patients with invasive arterial catheters during cardiopulmonary resuscitation and surgical cardiac or medical cardiac illness category., Interventions: None., Measurements and Main Results: Hemodynamic waveforms during cardiopulmonary resuscitation were analyzed on 113 patients, 88 surgical cardiac and 25 medical cardiac. A similar percent of surgical cardiac (51/88; 58%) and medical cardiac (17/25; 68%) patients reached the diastolic blood pressure targets (p = 0.488). Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients (p = 0.018), but not medical cardiac patients (p = 0.359). Fifty-three percent (16/30) of patients with single ventricles attained the target diastolic blood pressure. In patients with an open chest at the start of chest compressions, 11 of 20 (55%) attained the target diastolic blood pressure. In the 33 extracorporeal cardiopulmonary resuscitation patients, 16 patients (48%) met the diastolic blood pressure target with no difference between survivors and nonsurvivors (p = 0.296)., Conclusions: During resuscitation in an ICU, with invasive monitoring in place, diastolic blood pressure targets of greater than or equal to 25 mm Hg in infants and greater than or equal to 30 mm Hg in children can be achieved in patients with both surgical and medical heart disease. Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients, but not medical cardiac patients. Diastolic blood pressure targets were feasible to achieve in 1) single ventricle patients, 2) open chest physiology, and 3) extracorporeal cardiopulmonary resuscitation patients.

Objectives: To evaluate the prevalence of do-not-resuscitate status, assess the epidemiologic trends of do-not-resuscitate status, and assess the factors associated with do-not-resuscitate status in children after in-hospital cardiac arrest using large, multi-institutional data., Design: Generalized estimating equations logistic regression model was used to evaluate the trends of do-not-resuscitate status and evaluate the factors associated with do-not-resuscitate status after cardiac arrest., Setting: American Heart Association's Get With the Guidelines-Resuscitation Registry., Patients: Children (< 18 yr old) with an index in-hospital cardiac arrest and greater than or equal to 1 minute of documented chest compressions were included (2006-2015). Patients with no return of spontaneous circulation after cardiac arrest were excluded., Interventions: None., Measurements and Main Results: In total, 8,062 patients qualified for inclusion. Of these, 1,160 patients (14.4%) adopted do-not-resuscitate status after cardiac arrest. We found low rates of survival to hospital discharge among children with do-not-resuscitate status (do-not-resuscitate vs no do-not-resuscitate: 6.0% vs 69.7%). Our study found that rates of do-not-resuscitate status after cardiac arrest are highest in children with Hispanic ethnicity (16.4%), white race (15.0%), and treatment at institutions with larger PICUs (> 50 PICU beds: 17.8%) and at institutions located in North Central (17.6%) and South Atlantic/Puerto Rico (17.1%) regions of the United States. Do-not-resuscitate status was more common among patients with more preexisting conditions, longer duration of cardiac arrest, greater than 1 cardiac arrest, and among patients requiring extracorporeal cardiopulmonary resuscitation. We also found that trends of do-not-resuscitate status after cardiac arrest in children are decreasing in recent years (2013-2015: 13.8%), compared with previous years (2006-2009: 16.0%)., Conclusions: Patient-, hospital-, and regional-level factors are associated with do-not-resuscitate status after pediatric cardiac arrest. As cardiac arrest might be a signal of terminal chronic illness, a timely discussion of do-not-resuscitate status after cardiac arrest might help families prioritize quality of end-of-life care.

Objectives: Estimate the inter-rater reliability of critical care nurses performing a pediatric modification of the Glasgow Coma Scale in a contemporary PICU., Design: Prospective observation study., Setting: Large academic PICU., Patients/subjects: All 274 nurses with permanent assignments in the PICU were eligible to participate. A subset of 18 nurses were selected as study registered nurses. All PICU patients were eligible to participate., Interventions: None., Measurements and Main Results: PICU nurses were educated and demonstrated proficiency on a pediatric modification of the Glasgow Coma Scale we created to make it more applicable to a diverse PICU population that included patients who are sedated, mechanically ventilated, and/or have developmental disabilities. Each study registered nurse observed a sample of nurses perform the Glasgow Coma Scale, and they independently scored the Glasgow Coma Scale. Patients were categorized as having developmental disabilities if their preillness Pediatric Cerebral Performance Category score was greater than or equal to 3. Fleiss' Kappa (κ), intraclass correlation coefficient, and percent agreement assessed inter-rater reliability for each Glasgow Coma Scale component (eye, verbal, motor) and age-specific scale (≥ 2 and < 2-yr-old). The overall percent agreement between study registered nurses and nurses was 89% for the eye, 91% for the verbal, and 79% for the motor responses. Inter-rater reliability ranged from good (intraclass correlation coefficient = 0.75) to excellent (intraclass correlation coefficient = 0.96) for testable patients. Agreement on the motor response was significantly lower for children with developmental disabilities (< 2 yr: 59% vs 95%; p = 0.0012 and ≥ 2 yr: 55% vs 91%; p = 0.0012). Agreement was significantly worse for intermediate range Glasgow Coma Scale motor responses compared with responses at the extremes (e.g., motor responses 2, 3, 4 vs 1, 5, 6; p < 0.05)., Conclusions: A pediatric modification of the Glasgow Coma Scale performed by trained PICU nurses has excellent inter-rater reliability, although reliability was reduced in patients with developmental disabilities and for intermediate range Glasgow Coma Scale responses. Further research is needed to determine the effectiveness of this Glasgow Coma Scale modification to detect clinical deterioration.

Objectives: To evaluate the variation of hospital rates of delayed epinephrine administration in pediatric patients with nonshockable in-hospital cardiac arrest, and the association of those rates with event, 24-hour, and overall survival to hospital discharge., Design: A retrospective evaluation was performed. Delayed epinephrine was defined as greater than 5 minutes between the time the need for chest compressions was identified and epinephrine was administered. The main outcome was the association of hospital rate of delayed epinephrine administration with survival to hospital discharge. Secondary outcomes were event and 24-hour survival. Evaluation used hierarchical logistic regression and included 13 patient/event-level and seven hospital-level factors., Setting: Hospitals with greater than 6 months data in the American Heart Association's Get With the Guidelines-Resuscitation registry (2000-2016) and greater than or equal to five total pediatric cardiac arrests with nonshockable rhythm., Patients: Children less than 18 years old with index nonshockable in-hospital cardiac arrest treated with greater than or equal to one epinephrine dose., Interventions: None., Measurements and Main Results: One-thousand four-hundred sixty-two patients at 69 hospitals were included: 218 patients (14.9%) had epinephrine delay rates ranging from 0% to 80% of events (median, 15.6%; interquartile range, 7-25%). The median and interquartile range of hospital level delay was 16% (7-25%). Patient/event-level predictors of delayed epinephrine were asystole (odds ratio, 1.54 [95% CI, 1.10-2.16]) and insertion of an endotracheal tube (odds ratio, 1.86 [95% CI, 1.27-2.73]). Hospital size less than 200 compared with greater than or equal to 500 beds (odds ratio, 3.07 [95% CI, 1.22-7.73]) and ICU location (odds ratio, 0.51 [95% CI, 0.36-0.74]) were associated with epinephrine delay rates. After adjustment, increasing quartiles of epinephrine delay were associated with lower patient and hospital-level return of spontaneous circulation (p = 0.019, p = 0.006) and 24-hour survival (p = 0.018, p = 0.002) respectively, but not survival to discharge (p = 0.20, p = 0.24)., Conclusions: Delayed epinephrine administration following pediatric nonshockable in-hospital cardiac arrest varies significantly between hospitals. Hospitals with higher rates of delayed epinephrine administration had worse patient- and hospital-level outcomes after adjusting for multiple patient- and hospital-level factors. Delayed epinephrine administration may directly contribute to increased mortality risk and/or may be a marker of unmeasured elements of hospital resuscitation performance.

Objectives: To determine a level of oxygen desaturation from baseline that is associated with increased risk of tracheal intubation associated events in children with cyanotic and noncyanotic heart disease., Design: Retrospective analysis of prospectively collected data from the National Emergency Airway Registry for Children, an international multicenter quality improvement collaborative for airway management in critically ill children., Setting: Thirty-eight PICUs from July 2012 to December 2016., Patients: Children with cyanotic and noncyanotic heart disease who underwent tracheal intubation in a pediatric or cardiac ICU., Interventions: None., Measurements and Main Results: Our exposure of interest was oxygen desaturation measured by a fall in pulse oximetry from baseline after preoxygenation. Primary outcome was the occurrence of hemodynamic tracheal intubation associated events defined as cardiac arrest, hypotension or dysrhythmia. One-thousand nine-hundred ten children (cyanotic, 999; noncyanotic, 911) were included. Patients with cyanotic heart disease who underwent tracheal intubations were younger (p < 0.001) with higher Pediatric Index of Mortality 2 scores (p < 0.001), more likely to have a cardiac surgical diagnosis (p < 0.001), and less likely to have hemodynamic instability (p = 0.009) or neurologic failure as an indication (p = 0.008). Oxygen desaturation was observed more often in children with cyanotic versus noncyanotic heart disease (desaturation of 15% to < 30%: 23% vs 16%, desaturation ≥ 30%: 23% vs 17%; p < 0.001), with no significant difference in occurrence of hemodynamic tracheal intubation associated events (7.5% vs 6.9%; p = 0.618). After adjusting for confounders, oxygen desaturation by 30% or more is associated with increased odds for adverse hemodynamic events (odds ratio, 4.03; 95% CI, 2.12-7.67) for children with cyanotic heart disease and (odds ratio, 3.80; 95% CI, 1.96-7.37) for children with noncyanotic heart disease., Conclusions: Oxygen desaturation was more commonly observed during tracheal intubation in children with cyanotic versus noncyanotic heart disease. However, hemodynamic tracheal intubation associated event rates were similar. In both groups, oxygen desaturation greater than or equal to 30% was significantly associated with increased occurrence of hemodynamic tracheal intubation associated events.

Objectives: It is unknown if variation in tracheal intubation practice and outcomes exist across PICUs in different geographical regions. We hypothesized there would be differences in the process of care and adverse outcomes for tracheal intubation across PICUs in six different geographical regions (New Zealand, Japan, Singapore, Germany, India, and North America)., Design: Prospective multicenter pediatric tracheal intubation database (National Emergency Airway Registry for Children) SETTING:: Six non-North American (International) and 36 North American PICUs., Events: All PICU tracheal intubation encounters from July 2014 to June 2017 MEASUREMENTS AND MAIN RESULTS:: Adverse tracheal intubation-associated events and desaturation occurrence (oxygen saturation < 80%) were evaluated. A total of 1,134 and 9,376 TIs from International and North American PICUs were reported, respectively: primary tracheal intubation 9,060, endotracheal tube change 1,450. The proportion of tracheal intubations for endotracheal tube change was greater in International PICUs (37% vs 11%; p < 0.001). Median age for International tracheal intubations was younger compared with North America (0 yr [interquartile range, 0-2 yr] vs 1 yr (0-7 yr); p < 0.001). Among primary tracheal intubations, the most common indication was respiratory (International 67%, North American 63%; p = 0.049). Direct laryngoscopy was the most common device in both International (86%) and North American (74%) tracheal intubations. Occurrence of any adverse tracheal intubation-associated event was New Zealand 8%, Japan 17%, Singapore 9%, Germany 17%, and India 6%; International 11% versus North American 14%; p value equals to 0.003. Desaturation was reported less commonly in International PICUs: 13% versus North American 17%; p equals to 0.001. International PICUs used cuffed endotracheal tube less often (52% vs 95%; p < 0.001). Proportion of cuffed endotracheal tube use per PICU was inversely correlated with the rate of tube change (r = -0.67; p < 0.001)., Conclusions: There were both similarities and differences in tracheal intubation practice and outcomes across international PICUs. Fewer adverse tracheal intubation-associated events were reported from International versus North American PICUs. International PICUs used cuffed endotracheal tube less often and had higher proportion of endotracheal tube change.

Objectives: Cricoid pressure is often used to prevent regurgitation during induction and mask ventilation prior to high-risk tracheal intubation in critically ill children. Clinical data in children showing benefit are limited. Our objective was to evaluate the association between cricoid pressure use and the occurrence of regurgitation during tracheal intubation for critically ill children in PICU., Design: A retrospective cohort study of a multicenter pediatric airway quality improvement registry., Settings: Thirty-five PICUs within general and children's hospitals (29 in the United States, three in Canada, one in Japan, one in Singapore, and one in New Zealand)., Patients: Children (< 18 yr) with initial tracheal intubation using direct laryngoscopy in PICUs between July 2010 and December 2015., Interventions: None., Measurements and Main Results: Multivariable logistic regression analysis was used to evaluate the association between cricoid pressure use and the occurrence of regurgitation while adjusting for underlying differences in patient and clinical care factors. Of 7,825 events, cricoid pressure was used in 1,819 (23%). Regurgitation was reported in 106 of 7,825 (1.4%) and clinical aspiration in 51 of 7,825 (0.7%). Regurgitation was reported in 35 of 1,819 (1.9%) with cricoid pressure, and 71 of 6,006 (1.2%) without cricoid pressure (unadjusted odds ratio, 1.64; 95% CI, 1.09-2.47; p = 0.018). On multivariable analysis, cricoid pressure was not associated with the occurrence of regurgitation after adjusting for patient, practice, and known regurgitation risk factors (adjusted odds ratio, 1.57; 95% CI, 0.99-2.47; p = 0.054). A sensitivity analysis in propensity score-matched cohorts showed cricoid pressure was associated with a higher regurgitation rate (adjusted odds ratio, 1.01; 95% CI, 1.00-1.02; p = 0.036)., Conclusions: Cricoid pressure during induction and mask ventilation before tracheal intubation in the current ICU practice was not associated with a lower regurgitation rate after adjusting for previously reported confounders. Further studies are needed to determine whether cricoid pressure for specific indication with proper maneuver would be effective in reducing regurgitation events.

Objectives: Pediatric in-hospital cardiac arrest cardiopulmonary resuscitation quality metrics have been reported in few children less than 8 years. Our objective was to characterize chest compression fraction, rate, depth, and compliance with 2015 American Heart Association guidelines across multiple pediatric hospitals., Design: Retrospective observational study of data from a multicenter resuscitation quality collaborative from October 2015 to April 2017., Setting: Twelve pediatric hospitals across United States, Canada, and Europe., Patients: In-hospital cardiac arrest patients (age < 18 yr) with quantitative cardiopulmonary resuscitation data recordings., Interventions: None., Measurements and Main Results: There were 112 events yielding 2,046 evaluable 60-second epochs of cardiopulmonary resuscitation (196,669 chest compression). Event cardiopulmonary resuscitation metric summaries (median [interquartile range]) by age: less than 1 year (38/112): chest compression fraction 0.88 (0.61-0.98), chest compression rate 119/min (110-129), and chest compression depth 2.3 cm (1.9-3.0 cm); for 1 to less than 8 years (42/112): chest compression fraction 0.94 (0.79-1.00), chest compression rate 117/min (110-124), and chest compression depth 3.8 cm (2.9-4.6 cm); for 8 to less than 18 years (32/112): chest compression fraction 0.94 (0.85-1.00), chest compression rate 117/min (110-123), chest compression depth 5.5 cm (4.0-6.5 cm). "Compliance" with guideline targets for 60-second chest compression "epochs" was predefined: chest compression fraction greater than 0.80, chest compression rate 100-120/min, and chest compression depth: greater than or equal to 3.4 cm in less than 1 year, greater than or equal to 4.4 cm in 1 to less than 8 years, and 4.5 to less than 6.6 cm in 8 to less than 18 years. Proportion of less than 1 year, 1 to less than 8 years, and 8 to less than 18 years events with greater than or equal to 60% of 60-second epochs meeting compliance (respectively): chest compression fraction was 53%, 81%, and 78%; chest compression rate was 32%, 50%, and 63%; chest compression depth was 13%, 19%, and 44%. For all events combined, total compliance (meeting all three guideline targets) was 10% (11/112)., Conclusions: Across an international pediatric resuscitation collaborative, we characterized the landscape of pediatric in-hospital cardiac arrest chest compression quality metrics and found that they often do not meet 2015 American Heart Association guidelines. Guideline compliance for rate and depth in children less than 18 years is poor, with the greatest difficulty in achieving chest compression depth targets in younger children.

Objectives: As of July 2013, pediatric resident trainee guidelines in the United States no longer require proficiency in nonneonatal tracheal intubation. We hypothesized that laryngoscopy by pediatric residents has decreased over time, with a more pronounced decrease after this guideline change., Design: Prospective cohort study., Setting: Twenty-five PICUs at various children's hospitals across the United States., Patients: Tracheal intubations performed in PICUs from July 2010 to June 2016 in the multicenter tracheal intubation database (National Emergency Airway Registry for Children)., Intervention: None., Measurements and Main Results: Prospective cohort study in which all primary tracheal intubations occurring in the United States from July 2010 to June 2016 in the multicenter tracheal intubation database (National Emergency Airway Registry for Children) were analyzed. Participating PICU leaders were also asked to describe their local airway management training for residents. Resident participation trends over time, stratified by presence of a Pediatric Critical Care Medicine fellowship and airway training curriculum for residents, were described. A total of 9,203 tracheal intubations from 25 PICUs were reported. Pediatric residents participated in 16% of tracheal intubations as first laryngoscopists: 14% in PICUs with a Pediatric Critical Care Medicine fellowship and 34% in PICUs without one (p < 0.001). Resident participation decreased significantly over time (3.4% per year; p < 0.001). The decrease was significant in ICUs with a Pediatric Critical Care Medicine fellowship (p < 0.001) but not in ICUs without one (p = 0.73). After adjusting for site-level clustering, patient characteristics, and Pediatric Critical Care Medicine fellowship presence, the Accreditation Council for Graduate Medical Education guideline change was not associated with lower participation by residents (odds ratio, 0.86; 95% CI, 0.59-1.24; p = 0.43). The downward trend of resident participation was similar regardless of the presence of an airway curriculum for residents., Conclusion: Laryngoscopy by pediatric residents has substantially decreased over time. This downward trend was not associated with the 2013 Accreditation Council for Graduate Medical Education change in residency requirements.

Objective: To understand how routine bedside clinical neurologic assessments are performed in U.S. PICUs., Design: Electronic survey., Setting: Academic PICUs throughout the United States., Subjects: Faculty representatives from PICUs throughout the United States., Interventions: None., Measurements and Main Results: We surveyed how routine bedside neurologic assessments are reported to be performed in U.S. PICUs and the attitudes of respondents on the utility of these assessments. The survey contained questions regarding 1) components of neurologic assessments; 2) frequency of neurologic assessments; 3) documentation and communication of changes in neurologic assessment; and 4) optimization of neurologic assessments. Surveys were received from 64 of 67 institutions (96%). Glasgow Coma Scale and pupillary reflex were the most commonly reported assessments (80% and 92% of institutions, respectively). For patients with acute brain injury, 95% of institutions performed neurologic assessments hourly although assessment frequency was more variable for patients at low risk of developing brain injury and those at high risk for brain injury, but without overt injury. In 73% of institutions, any change detected on routine neuroassessment was communicated to providers, whereas in 27%, communication depended on the severity or degree of neurologic decline. Seventy percent of respondents thought that their current practice for assessing and monitoring neurologic status was suboptimal. Only 57% felt that the Glasgow Coma Scale was a valuable tool for the serial assessment of neurologic function in the ICU. Ninety-two percent felt that a standardized approach to assessing and documenting preillness neurologic function would be valuable., Conclusions: Routine neurologic assessments are reported to be conducted in nearly all academic PICUs in the United States with fellowship training programs although the content, frequency, and triggers for communication vary between institutions. Most physicians felt that the current paradigms for neurologic assessments are suboptimal. These data suggest that optimizing and standardizing routine bedside nursing neurologic assessments may be warranted.

Objectives: Duplicative institutional review board/research ethics committee review for multicenter studies may impose administrative burdens and inefficiencies affecting study implementation and quality. Understanding variability in site-specific institutional review board/research ethics committee assessment and barriers to using a single review committee (an increasingly proposed solution) can inform a more efficient process. We provide needed data about the regulatory oversight process for the Sepsis PRevalence, OUtcomes, and Therapies multicenter point prevalence study., Design: Survey., Setting: Sites invited to participate in Sepsis PRevalence, OUtcomes, and Therapies., Subjects: Investigators at sites that expressed interest and/or participated in Sepsis PRevalence, OUtcomes, and Therapies., Interventions: None., Measurements and Main Results: Using an electronic survey, we collected data about 1) logistics of protocol submission, 2) institutional review board/research ethics committee requested modifications, and 3) use of a single institutional review board (for U.S. sites). We collected surveys from 104 of 167 sites (62%). Of the 97 sites that submitted the protocol for institutional review board/research ethics committee review, 34% conducted full board review, 54% expedited review, and 4% considered the study exempt. Time to institutional review board/research ethics committee approval required a median of 34 (range 3-186) days, which took longer at sites that required protocol modifications (median [interquartile range] 50 d [35-131 d] vs 32 d [14-54 d)]; p = 0.02). Enrollment was delayed at eight sites due to prolonged (> 50 d) time to approval. Of 49 U.S. sites, 43% considered using a single institutional review board, but only 18% utilized this option. Time to final approval for U.S. sites using the single institutional review board was 62 days (interquartile range, 34-70 d) compared with 34 days (interquartile range, 15-54 d) for nonsingle institutional review board sites (p = 0.16)., Conclusions: Variability in regulatory oversight was evident for this minimal-risk observational research study, most notably in the category of type of review conducted. Duplicative review prolonged time to protocol approval at some sites. Use of a single institutional review board for U.S. sites was rare and did not improve efficiency of protocol approval. Suggestions for minimizing these challenges are provided.

Objectives: Evaluate differences in tracheal intubation-associated events and process variances (i.e., multiple intubation attempts and oxygen desaturation) between pediatric cardiac ICUs and noncardiac PICUs in children with underlying cardiac disease., Design: Retrospective cohort study using a multicenter tracheal intubation quality improvement database (National Emergency Airway Registry for Children)., Setting: Thirty-six PICUs (five cardiac ICUs, 31 noncardiac ICUs) from July 2012 to March 2016., Patients: Children with medical or surgical cardiac disease who underwent intubation in an ICU., Interventions: None., Measurements and Main Results: Our primary outcome was the rate of any adverse tracheal intubation-associated event. Secondary outcomes were severe tracheal intubation-associated events, multiple tracheal intubation attempt rates, and oxygen desaturation. There were 1,502 tracheal intubations in children with underlying cardiac disease (751 in cardiac ICUs, 751 in noncardiac ICUs) reported. Cardiac ICUs and noncardiac ICUs had similar proportions of patients with surgical cardiac disease. Patients undergoing intubation in cardiac ICUs were younger (median age, 1 mo [interquartile range, 0-6 mo]) compared with noncardiac ICUs (median 3 mo [interquartile range, 1-11 mo]; p < 0.001). Tracheal intubation-associated event rates were not different between cardiac ICUs and noncardiac ICUs (16% vs 19%; adjusted odds ratio, 0.74; 95% CI, 0.54-1.02; p = 0.069). However, in a sensitivity analysis comparing cardiac ICUs with mixed ICUs (i.e., ICUs caring for children with either general pediatric or cardiac diseases), cardiac ICUs had decreased odds of adverse events (adjusted odds ratio, 0.71; 95% CI, 0.52-0.97; p = 0.033). Rates of severe tracheal intubation-associated events and multiple attempts were similar. Desaturations occurred more often during intubation in cardiac ICUs (adjusted odds ratio, 1.61; 95% CI, 1.04-1.15; p = 0.002)., Conclusions: In children with underlying cardiac disease, rates of adverse tracheal intubation-associated events were not lower in cardiac ICUs as compared to noncardiac ICUs, even after adjusting for differences in patient characteristics and care models.

Objectives: To develop a clinical prediction score for predicting mortality in children following return of spontaneous circulation after in-hospital cardiac arrest., Design: Observational study using prospectively collected data., Setting: This was an analysis using data from the Get With The Guidelines-Resuscitation registry between January 2000 and December 2015., Patients: Pediatric patients (< 18 yr old) who achieved return of spontaneous circulation., Interventions: None., Measurements and Main Results: The primary outcome was in-hospital mortality. Patients were divided into a derivation (3/4) and validation (1/4) cohort. A prediction score was developed using a multivariable logistic regression model with backward selection. Patient and event characteristics for the derivation cohort (n = 3,893) and validation cohort (n = 1,297) were similar. Seventeen variables associated with the outcome remained in the final reduced model after backward elimination. Predictors of in-hospital mortality included age, illness category, pre-event characteristics, arrest location, day of the week, nonshockable pulseless rhythm, duration of chest compressions, and interventions in place at time of arrest. The C-statistic for the final score was 0.77 (95% CI, 0.75-0.78) in the derivation cohort and 0.77 (95% CI, 0.74-0.79) in the validation cohort. The expected versus observed mortality plot indicated good calibration in both the derivation and validation cohorts. The score showed a stepwise increase in mortality with an observed mortality of less than 15% for scores 0-9 and greater than 80% for scores greater than or equal to 25. The model also performed well for neurologic outcome and in sensitivity analyses for events within the past 5 years and for patients with or without a pulse at the onset of chest compressions., Conclusions: We developed and internally validated a prediction score for initial survivors of pediatric in-hospital cardiac arrest. This prediction score may be useful for prognostication following cardiac arrest, stratifying patients for research, and guiding quality improvement initiatives.

Objective: Waveform capnography use has been incorporated into guidelines for the confirmation of tracheal intubation. We aim to describe the trend in waveform capnography use in emergency departments and PICUs and assess the association between waveform capnography use and adverse tracheal intubation-associated events., Design: A multicenter retrospective cohort study., Setting: Thirty-four hospitals (34 ICUs and nine emergency departments) in the National Emergency Airway Registry for Children quality improvement initiative., Patients: Primary tracheal intubation in children younger than 18 years., Interventions: None., Measurements and Main Results: Patient, provider, and practice data for tracheal intubation procedure including a type of end-tidal carbon dioxide measurement, as well as the procedural safety outcomes, were prospectively collected. The use of waveform capnography versus colorimetry was evaluated in association with esophageal intubation with delayed recognition, cardiac arrest, and oxygen desaturation less than 80%. During January 2011 and December 2015, 9,639 tracheal intubations were reported. Waveform capnography use increased over time (39% in 2010 to 53% in 2015; p < 0.001), whereas colorimetry use decreased (< 0.001). There was significant variability in waveform capnography use across institutions (median 49%; interquartile range, 25-85%; p < 0.001). Capnography was used more often in emergency departments as compared with ICUs (66% vs. 49%; p < 0.001). The rate of esophageal intubation with delayed recognition was similar with waveform capnography versus colorimetry (0.39% vs. 0.46%; p = 0.62). The rate of cardiac arrest was also similar (p = 0.49). Oxygen desaturation occurred less frequently when capnography was used (17% vs. 19%; p = 0.03); however, this was not significant after adjusting for patient and provider characteristics., Conclusions: Significant variations existed in capnography use across institutions, with the use increasing over time in both emergency departments and ICUs. The use of capnography during intubation was not associated with esophageal intubation with delayed recognition or the occurrence of cardiac arrest.

Objectives: External laryngeal manipulation is a commonly used maneuver to improve visualization of the glottis during tracheal intubation in children. However, the effectiveness to improve tracheal intubation attempt success rate in the nonanesthesia setting is not clear. The study objective was to evaluate the association between external laryngeal manipulation use and initial tracheal intubation attempt success in PICUs., Design: A retrospective observational study using a multicenter emergency airway quality improvement registry., Setting: Thirty-five PICUs within general and children's hospitals (29 in the United States, three in Canada, one in Japan, one in Singapore, and one in New Zealand)., Patients: Critically ill children (< 18 years) undergoing initial tracheal intubation with direct laryngoscopy in PICUs between July 1, 2010, and December 31, 2015., Measurements and Main Results: Propensity score-matched analysis was performed to evaluate the association between external laryngeal manipulation and initial attempt success while adjusting for underlying differences in patient and clinical care factors: age, obesity, tracheal intubation indications, difficult airway features, provider training level, and neuromuscular blockade use. External laryngeal manipulation was defined as any external force to the neck during laryngoscopy. Of the 7,825 tracheal intubations, the initial tracheal intubation attempt was successful in 1,935/3,274 intubations (59%) with external laryngeal manipulation and 3,086/4,551 (68%) without external laryngeal manipulation (unadjusted odds ratio, 0.69; 95% CI, 0.62-0.75; p < 0.001). In propensity score-matched analysis, external laryngeal manipulation remained associated with lower initial tracheal intubation attempt success (adjusted odds ratio, 0.93; 95% CI, 0.90-0.95; p < 0.001)., Conclusions: External laryngeal manipulation during direct laryngoscopy was associated with lower initial tracheal intubation attempt success in critically ill children, even after adjusting for underlying differences in patient factors and provider levels. The indiscriminate use of external laryngeal manipulation cannot be recommended.

Objectives: Although clinical and pharmacologic guidelines exist for the practice of cardiopulmonary resuscitation in children (Pediatric Advanced Life Support), the practice of extracorporeal cardiopulmonary resuscitation in pediatric cardiac patients remains without universally accepted standards. We aim to explore variation in extracorporeal cardiopulmonary resuscitation procedures by surveying clinicians who care for this high-risk patient population., Design: A 28-item cross-sectional survey was distributed via a web-based platform to clinicians focusing on cardiopulmonary resuscitation practices and extracorporeal membrane oxygenation team dynamics immediately prior to extracorporeal membrane oxygenation cannulation., Settings: Pediatric hospitals providing extracorporeal mechanical support services to patients with congenital and/or acquired heart disease., Subjects: Critical care/cardiology specialist physicians, cardiothoracic surgeons, advanced practice nurse practitioners, respiratory therapists, and extracorporeal membrane oxygenation specialists., Interventions: None., Measurements and Main Results: Survey web links were distributed over a 2-month period with critical care and/or cardiology physicians comprising the majority of respondents (75%). Nearly all respondents practice at academic/teaching institutions (97%), 89% were from U.S./Canadian institutions and 56% reported less than 10 years of clinical experience. During extracorporeal cardiopulmonary resuscitation, a majority of respondents reported adherence to guideline recommendations for epinephrine bolus dosing (64%). Conversely, 19% reported using only one to three epinephrine bolus doses regardless of extracorporeal cardiopulmonary resuscitation duration. Inotropic support is held after extracorporeal membrane oxygenation cannulation "most of the time" by 58% of respondents and 94% report using afterload reducing/antihypertensive agents "some" to "most of the time" after achieving full extracorporeal membrane oxygenation support. Interruptions in chest compressions are common during active cannulation according to 77% of respondents., Conclusions: The results of this survey identify wide variability in resuscitative practices during extracorporeal cardiopulmonary resuscitation in the pediatric cardiac population. The deviations from established Pediatric Advanced Life Support CPR guidelines support a call for further inquiry into the pharmacologic and logistical care surrounding extracorporeal cardiopulmonary resuscitation.

Objectives: Oxygen desaturation during tracheal intubation is known to be associated with adverse ICU outcomes in critically ill children. We aimed to determine the occurrence and severity of desaturation during tracheal intubations and the association with adverse hemodynamic tracheal intubation-associated events., Design: Retrospective cohort study as a part of the National Emergency Airway Registry for Children Network's quality improvement project from January 2012 to December 2014., Setting: International PICUs., Patients: Critically ill children younger than 18 years undergoing primary tracheal intubations in the ICUs., Interventions: tracheal intubation processes of care and outcomes were prospectively collected using standardized operational definitions. We defined moderate desaturation as oxygen saturation less than 80% and severe desaturation as oxygen saturation less than 70% during tracheal intubation procedures in children with initial oxygen saturation greater than 90% after preoxygenation. Adverse hemodynamic tracheal intubation-associated event was defined as cardiac arrests, hypo or hypertension requiring intervention, and dysrhythmia., Measurements and Main Results: A total of 5,498 primary tracheal intubations from 31 ICUs were reported. Moderate desaturation was observed in 19.3% associated with adverse hemodynamic tracheal intubation-associated events (9.8% among children with moderate desaturation vs 4.4% without desaturation; p < 0.001). Severe desaturation was observed in 12.9% of tracheal intubations, also significantly associated with hemodynamic tracheal intubation-associated events. After adjusting for patient, provider, and practice factors, the occurrence of moderate desaturation was independently associated with hemodynamic tracheal intubation-associated events: adjusted odds ratio 1.83 (95% CI, 1.34-2.51; p < 0.001). The occurrence of severe desaturation was also independently associated with hemodynamic tracheal intubation-associated events: adjusted odds ratio 2.16 (95% CI, 1.54-3.04; p < 0.001). Number of tracheal intubation attempts was also significantly associated with the frequency of moderate and severe desaturations (p < 0.001)., Conclusions: In this large tracheal intubation quality improvement database, we found moderate and severe desaturation are reported among 19% and 13% of all tracheal intubation encounters. Moderate and severe desaturations were independently associated with the occurrence of adverse hemodynamic events. Future quality improvement interventions may focus to reduce desaturation events.
