- Abstract
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.

- Abstract
Objective: Bedside ultrasound for hemodynamic evaluation in critically ill children is increasingly recognized as an important skill for pediatric critical care medicine providers. Our institution implemented a training curriculum leading to institutional credentialing for pediatric critical care providers in nonprocedural bedside ultrasound core applications. We hypothesized that hemodynamic studies performed or supervised by credentialed providers (credentialed providers group) have better image quality and greater accuracy in interpretation than studies performed by non-credentialed providers without supervision (non-credentialed providers group)., Design: Retrospective descriptive study., Setting: Single-center tertiary non-cardiac 55-bed PICU in a children's hospital., Patients: Patients from October 2013 to January 2015, with hemodynamic bedside ultrasound performed and interpreted by pediatric critical care providers exposed to bedside ultrasound training., Interventions: A cardiologist blinded to performer scored hemodynamic bedside ultrasound image quality for five core cardiac views (excellent = 3, good = 2, fair = 1, unacceptable = 0; median = quality score) and interpretation within 5 hemodynamic domains (agreement = 3, minor disagreement = 2, major disagreement = 1; median = interpretation score), as well as a global assessment of interpretation., Measurements and Main Results: Eighty-one studies (45 in the credentialed providers group and 36 in the non-credentialed providers group) were evaluated. There was no statistically significant difference in quality score between groups (median: 1.4 [interquartile range: 0.8-1.8] vs median: 1.2 [interquartile range: 0.75-1.6]; p = 0.14]. Studies in the credentialed providers group had higher interpretation score than those in the non-credentialed providers group (median: 3 [interquartile range: 2.5-3) vs median: 2.67 [interquartile range: 2.25-3]; p = 0.04). Major disagreement between critical care provider and cardiology review occurred in 25 of 283 hemodynamic domains assessed (8.8%), with no statistically significant difference between credentialed providers and non-credentialed providers groups (6.1% vs 11.9%; p = 0.12)., Conclusion: Hemodynamic bedside ultrasound performed or supervised by credentialed pediatric critical care providers had more accurate interpretation than studies performed by unsupervised non-credentialed providers. A rigorous pediatric critical care medicine bedside ultrasound credentialing program can train intensivists to attain adequate images and interpret those images appropriately.

- Abstract
Objectives: To examine the feasibility of deploying a virtual web service for sharing data within a research network, and to evaluate the impact on data consistency and quality., Material and Methods: Virtual machines (VMs) encapsulated an open-source, semantically and syntactically interoperable secure web service infrastructure along with a shadow database. The VMs were deployed to 8 Collaborative Pediatric Critical Care Research Network Clinical Centers., Results: Virtual web services could be deployed in hours. The interoperability of the web services reduced format misalignment from 56% to 1% and demonstrated that 99% of the data consistently transferred using the data dictionary and 1% needed human curation., Conclusions: Use of virtualized open-source secure web service technology could enable direct electronic abstraction of data from hospital databases for research purposes., (© The Author 2015.

- Abstract
Importance: Functional status assessment methods are important as outcome measures for pediatric critical care studies., Objective: To investigate the relationships between the 2 functional status assessment methods appropriate for large-sample studies, the Functional Status Scale (FSS) and the Pediatric Overall Performance Category and Pediatric Cerebral Performance Category (POPC/PCPC) scales., Design, Setting, and Participants: Prospective cohort study with random patient selection at 7 sites and 8 children's hospitals with general/medical and cardiac/cardiovascular pediatric intensive care units (PICUs) in the Collaborative Pediatric Critical Care Research Network. Participants included all PICU patients younger than 18 years., Main Outcomes and Measures: Functional Status Scale and POPC/PCPC scores determined at PICU admission (baseline) and PICU discharge. We investigated the association between the baseline and PICU discharge POPC/PCPC scores and the baseline and PICU discharge FSS scores, the dispersion of FSS scores within each of the POPC/PCPC ratings, and the relationship between the FSS neurologic components (FSS-CNS) and the PCPC., Results: We included 5017 patients. We found a significant (P < .001) difference between FSS scores in each POPC or PCPC interval, with an FSS score increase with each worsening POPC/PCPC rating. The FSS scores for the good and mild disability POPC/PCPC ratings were similar and increased by 2 to 3 points for the POPC/PCPC change from mild to moderate disability, 5 to 6 points for moderate to severe disability, and 8 to 9 points for severe disability to vegetative state or coma. The dispersion of FSS scores within each POPC and PCPC rating was substantial and increased with worsening POPC and PCPC scores. We also found a significant (P < .001) difference between the FSS-CNS scores between each of the PCPC ratings with increases in the FSS-CNS score for each higher PCPC rating., Conclusions and Relevance: The FSS and POPC/PCPC system are closely associated. Increases in FSS scores occur with each higher POPC and PCPC rating and with greater magnitudes of change as the dysfunction severity increases. However, the dispersion of the FSS scores indicated a lack of precision in the POPC/PCPC system when compared with the more objective and granular FSS. The relationship between the PCPC and the FSS-CNS paralleled the relationship between the FSS and POPC/PCPC system.

- Abstract
Objective: To investigate the effectiveness of brief bedside "booster" cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers., Design: Prospective, randomized trial., Setting: General pediatric wards at Children's Hospital of Philadelphia., Subjects: Sixty-nine Basic Life Support-certified hospital-based providers., Intervention: CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback., Measurements and Main Results: Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min(-1) and <120 min(-1)); 71% met minimum depth targets (depth, >38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and overall CPR compliance, 43% to 78% [p < .02]; automated feedback only: rate, 70% to 96% [p = .02], depth, 61% to 100% [p < .01], and overall CPR compliance, 35% to 96% [p < .01]; and instructor training combined with automated feedback: rate 48% to 100% [p < .01], depth, 78% to 100% [p < .02], and overall CPR compliance, 30% to 100% [p < .01])., Conclusions: Before booster CPR instruction, most certified Pediatric Basic Life Support providers did not perform guideline-compliant CPR. After a brief bedside training, CPR quality improved irrespective of training content (instructor vs. automated feedback). Future studies should investigate bedside training to improve CPR quality during actual pediatric cardiac arrests.

- Abstract
Introduction: The Privacy Rule, a follow-up to the Health Insurance Portability and Accountability Act, limits distribution of protected health information. Compliance with the Privacy Rule is particularly challenging for prehospital research, because investigators often seek data from multiple emergency medical services (EMS) and receiving hospitals., Objective: To describe the impact of the Privacy Rule on prehospital research and to present strategies to optimize data collection in compliance with the Privacy Rule. Methods. The CanAm Pediatric Cardiopulmonary Arrest Study Group has previously conducted a multicentered observational study involving children with out-of-hospital cardiac arrest. In the current study, we used a survey to assess site-specific methods of compliance with the Privacy Rule and the extent to which such strategies were successful., Results: The previously conducted observational study included collection of data from a total of 66 EMS agencies (range of 1-37 per site). Data collection from EMS providers was complicated by the lack of a systematic approval mechanism for the research use of EMS records and by incomplete resuscitation records. Agencies approached for approval to release EMS data for study purposes included Department of Health Institutional Review Boards, Fire Commissioners, and Commissioners of Health. The observational study included collection of data from a total of 164 receiving hospitals (range of 1-63 per site). Data collection from receiving hospitals was complicated by the varying requirements of receiving hospitals for the release of patient survival data., Conclusions: Obtaining complete EMS and hospital data is challenging but is vital to the conduct of prehospital research. Obtaining approval from city or state level IRBs or Privacy Boards may help optimize data collection. Uniformity of methods to adhere to regulatory requirements would ease the conduct of prehospital research.

- Abstract
Study Objective: We systematically summarize pediatric out-of-hospital cardiac arrest epidemiology and assess knowledge of effects of specific out-of-hospital interventions., Methods: We conducted a comprehensive review of published articles from 1966 to 2004, available through MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EmBase, and the Cochrane Registry, describing outcomes of children younger than 18 years with an out-of-hospital cardiac arrest. Patient characteristics, process of care, and outcomes were compared using pediatric Utstein outcome report guidelines. Effects of out-of-hospital care processes on survival outcomes were summarized., Results: Forty-one studies met inclusion criteria; 8 complied with Utstein reporting guidelines. Included in the review were 5,363 patients: 12.1% survived to hospital discharge, and 4% survived neurologically intact. Trauma patients (n=2,299) had greater overall survival (21.9%, 6.8% intact); a separate examination of studies with more rigorous cardiac arrest definition showed poorer survival (1.1% overall, 0.3% neurologically intact). Submersion injury-associated arrests (n=442) had greater overall survival (22.7%, 6% intact). Pooled data analysis of bystander cardiopulmonary resuscitation and witnessed arrest status showed increased likelihood of survival (relative risk 1.99, 95% confidence interval 1.54 to 2.57) for witnessed arrests. The effect of bystander cardiopulmonary resuscitation is difficult to determine because of study heterogeneity., Conclusion: Outcomes from out-of-hospital pediatric cardiac arrest are generally poor. Variability may exist in survival by patient subgroups, but differences are hard to accurately characterize. Conformity with Utstein guidelines for reporting and research design is incomplete. Witnessed arrest status remains associated with improved survival. The need for prospective controlled trials remains a high priority.

- Abstract
Objective: To evaluate published data regarding the treatment of prolonged pediatric defibrillation, with special emphasis on the use of attenuated adult biphasic shocks for pediatric defibrillation., Design: Review relevant human and animal literature., Results: Rhythm analysis algorithms from two manufacturers of automated external defibrillators can accurately distinguish shockable from nonshockable rhythms in children. Theoretical considerations and transthoracic impedance data from animals and children suggest that pediatric defibrillation doses should not necessarily vary in a simple weight-based manner. Two piglet studies have established that an attenuated adult biphasic dosage can be successfully used for 3.5- to 24-kg animals in ventricular fibrillation. One study established that the attenuated adult biphasic dosage was at least as safe and effective as the standard monophasic weight-based dosing., Conclusion: This review supports the American Heart Association's new guidelines for pediatric automated external defibrillator usage: "Automated external defibrillators may be used for children 1 to 8 yrs of age who have no signs of circulation. Ideally the device should deliver a pediatric dose. The arrhythmia detection system used in the device should demonstrate high specificity for pediatric shockable rhythms, i.e., it will not recommend delivery of a shock for nonshockable rhythms."

ObjectivesThe 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.DesignMulticenter 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).SettingData source was the ICU-RESUScitation Project ("ICU-RESUS;" NCT028374497), a prospective, multicenter, cluster randomized interventional trial.PatientsChildren (≤ 18 yr) who received cardiopulmonary resuscitation while admitted to the ICU and were enrolled in ICU-RESUS.InterventionsNone.Measurements and main resultsAmong 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).ConclusionsUsing 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.

BackgroundPediatric Intensive Care Unit (PICU) teams provide care for critically ill children with diverse and often complex medical and surgical conditions. Researchers often lack guidance on an approach to select the best outcomes when evaluating this critically ill population. Studies would be enhanced by incorporating multi-stakeholder preferences to better evaluate clinical care. This manuscript outlines the methodology currently being used to develop a PICU Core Outcome Set (COS). This PICU COS utilizes mixed methods, an inclusive stakeholder approach, and a modified Delphi consensus process that will serve as a resource for PICU research programs.MethodsA Scoping Review of the PICU literature evaluating outcomes after pediatric critical illness, a qualitative study interviewing PICU survivors and their parents, and other relevant literature will serve to inform a modified, international Delphi consensus process. The Delphi process will derive a set of minimum domains for evaluation of outcomes of critically ill children and their families. Delphi respondents include researchers, multidisciplinary clinicians, families and former patients, research funding agencies, payors, and advocates. Consensus meetings will refine and finalize the domains of the COS, outline a battery instruments for use in future studies, and prepare for extensive dissemination for broad implementation.DiscussionThe PICU COS will be a guideline resource for investigators to assure that outcomes most important to all stakeholders are considered in PICU clinical research in addition to those deemed most important to individual scientists.Trial registrationCOMET database (http://www.comet-initiative.org/, Record ID 1131, 01/01/18).

ObjectivesLimited data exist on the effects of extracorporeal membrane oxygenation on pharmacokinetics of cefepime in critically ill pediatric patients. The objective was to describe cefepime disposition in children treated with extracorporeal membrane oxygenation using population pharmacokinetic modeling.DesignMulticenter, prospective observational study.SettingThe pediatric and cardiac ICUs of six sites of the Collaborative Pediatric Critical Care Research Network.PatientsSeventeen critically ill children (30 d to < 2 yr old) on extracorporeal membrane oxygenation who received cefepime as standard of care between January 4, 2014, and August 24, 2015, were enrolled.InterventionsNone.Measurements and main resultsA pharmacokinetic model was developed to evaluate cefepime disposition differences due to extracorporeal membrane oxygenation. A two-compartment model with linear elimination, weight effects on clearance, intercompartmental clearance (Q), central volume of distribution (V1), and peripheral volume of distribution (V2) adequately described the data. The typical value of clearance in this study was 7.1 mL/min (1.9 mL/min/kg) for a patient weighing 5.8 kg. This value decreased by approximately 40% with the addition of renal replacement therapy. The typical value for V1 was 1,170 mL. In the setting of blood transfusions, V1 increased by over two-fold but was reduced with increasing age of the extracorporeal membrane oxygenation circuit oxygenator.ConclusionsCefepime clearance was reduced in pediatric patients treated with extracorporeal membrane oxygenation compared with previously reported values in children not receiving extracorporeal membrane oxygenation. The model demonstrated that the age of the extracorporeal membrane oxygenation circuit oxygenator is inversely correlated to V1. For free cefepime, only 14 of the 19 doses (74%) demonstrated a fT_minimum inhibitory concentration of 16 mg/L, an appropriate target for the treatment of pseudomonal infections, for greater than 70% of the dosing interval. Pediatric patients on extracorporeal membrane oxygenation might benefit from the addition of therapeutic drug monitoring of cefepime to assure appropriate dosing.

BackgroundOn the basis of laboratory cardiopulmonary resuscitation (CPR) investigations and limited adult data demonstrating that survival depends on attaining adequate arterial diastolic blood pressure (DBP) during CPR, the American Heart Association recommends using blood pressure to guide pediatric CPR. However, evidence-based blood pressure targets during pediatric CPR remain an important knowledge gap for CPR guidelines.MethodsAll children ≥37 weeks' gestation and

ObjectivesICU length of stay is an important measure of resource use and economic performance. Our primary aims were to characterize the utilization of PICU beds and to develop a new model for PICU length of stay.DesignProspective cohort. The main outcomes were factors associated with PICU length of stay and the performance of a regression model for length of stay.SettingEight PICUs.PatientsRandomly selected patients (newborn to 18 yr) from eight PICUs were enrolled from December 4, 2011, to April 7, 2013. Data consisted of descriptive, diagnostic, physiologic, and therapeutic information.InterventionsNone.Measurements and main resultsThe mean length of stay for was 5.0 days (SD, 11.1), with a median of 2.0 days. The 50.6% of patients with length of stay less than 2 days consumed only 11.1% of the days of care, whereas the 19.6% of patients with length of stay 4.9-19 days and the 4.6% with length of stay greater than or equal to 19 days consumed 35.7% and 37.6% of the days of care, respectively. Longer length of stay was observed in younger children, those with cardiorespiratory disease, postintervention cardiac patients, and those who were sicker assessed by Pediatric Risk of Mortality scores receiving more intensive therapies. Patients in the cardiac ICU stayed longer than those in the medical ICU. The length of stay model using descriptive, diagnostic, severity, and therapeutic factors performed well (patient-level R-squared of 0.42 and institution-level R-squared of 0.76). Standardized (observed divided by expected) length of stay ratios at the individual sites ranged from 0.87 to 1.09.ConclusionsPICU bed utilization was dominated by a minority of patients. The 5% of patients staying the longest used almost 40% of the bed days. The multivariate length of stay model used descriptive, diagnostic, therapeutic, and severity factors and has potential applicability for internal and external benchmarking.

Importance:Out-of-hospital cardiac arrest (OHCA) occurs in more than 6000 children each year in the United States, with survival rates of less than 10% and severe neurologic morbidity in many survivors. Post-cardiac arrest hypotension can occur, but its frequency and association with survival have not been well described during targeted temperature management. Objective:To determine whether hypotension is associated with survival to discharge in children and adolescents after resuscitation from OHCA. Design, Setting, and Participants:This post hoc secondary analysis of the Therapeutic Hypothermia After Pediatric Cardiac Arrest (THAPCA) trial included 292 pediatric patients older than 48 hours and younger than 18 years treated in 36 pediatric intensive care units from September 1, 2009, through December 31, 2012. Participants underwent therapeutic hypothermia (33.0°C) vs therapeutic normothermia (36.8°C) for 48 hours. All participants had hourly systolic blood pressure measurements documented during the initial 6 hours of temperature intervention. Hourly blood pressures beginning at the time of temperature intervention (time 0) were normalized for age, sex, and height. Early hypotension was defined as a systolic blood pressure less than the fifth percentile during the first 6 hours after temperature intervention. With use of forward stepwise logistic regression, covariates of interest (age, sex, initial cardiac rhythm, any preexisting condition, estimated duration of cardiopulmonary resuscitation [CPR], primary cause of cardiac arrest, temperature intervention group, night or weekend cardiac arrest, witnessed status, and bystander CPR) were evaluated in the final model. Data were analyzed from February 5, 2016, through June 13, 2017. Exposures:Hypotension. Main Outcomes and Measure:Survival to hospital discharge. Results:Of 292 children (194 boys [66.4%] and 98 girls [33.6%]; median age, 23.0 months [interquartile range, 5.0-105.0 months]), 78 (26.7%) had at least 1 episode of early hypotension. No difference was observed between the therapeutic hypothermia and therapeutic normothermia groups in the prevalence of hypotension during induction and maintenance (73 of 153 [47.7%] vs 72 of 139 [51.8%]; P = .50) or rewarming (35 of 118 [29.7%] vs 19 of 95 [20.0%]; P = .10) during the first 72 hours. Participants who had early hypotension were less likely to survive to hospital discharge (20 of 78 [25.6%] vs 93 of 214 [43.5%]; adjusted odds ratio, 0.39; 95% CI, 0.20-0.74). Conclusions and Relevance:In this post hoc secondary analysis of the THAPCA trial, 26.7% of participants had hypotension within 6 hours after temperature intervention. Early post-cardiac arrest hypotension was associated with lower odds of discharge survival, even after adjusting for covariates of interest.

Purpose Angiopoietin 2 (Ang2) and soluble receptor for advanced glycation end products (sRAGE) are markers of endothelial and pulmonary epithelial damage with prognostic implications in adult acute respiratory distress syndrome (ARDS), but unclear significance in pediatric ARDS (PARDS). Methods This was a prospective, observational study in children with PARDS (2012 Berlin and 2015 PALICC definitions) at the Children's Hospital of Philadelphia. Plasma was collected within 48 h of PARDS onset and biomarkers quantified by enzyme-linked immunosorbent assay. Results In 82 children with PARDS (12 deaths, 15 %), Ang2 and sRAGE were higher in non-survivors than survivors (p < 0.01 for both). Mortality was highest in patients with Ang2 and sRAGE levels both above median values. Ang2 and sRAGE correlated with the number of non-pulmonary organ failures (both p < 0.001). Ang2 was higher in indirect lung injury and in immunocompromised children. In stratified analysis, both Ang2 and sRAGE were associated with mortality only in direct lung injury and in immunocompetent children, with no association evident in indirect lung injury or in immunocompromised children. Conclusions Ang2 and sRAGE in early PARDS were higher in non-survivors than survivors and strongly correlated with number of non-pulmonary organ failures. When stratified by type of lung injury, Ang2 and sRAGE were associated with mortality only in direct lung injury. Similarly, when stratified by immunocompromised status, Ang2 and sRAGE were associated with mortality only in immunocompetent children. The utility of these biomarkers for prognostication and risk stratification requires investigation., Author(s): Nadir Yehya [sup.1] [sup.3], Neal J. Thomas [sup.2], Nuala J. Meyer [sup.3], Jason D.

Background: There are limited data on the use of video laryngoscopy for pediatric patients outside of the operating room. Aim: Our primary aim was to evaluate whether implementation of video laryngoscopy‐guided coaching for tracheal intubation is feasible with a high level of compliance and associated with a reduction in adverse tracheal intubation‐associated events. Methods: This is a pre‐post observational study of video laryngoscopy implementation with standardized coaching language for tracheal intubation in a single‐center, pediatric intensive care unit. The use of video laryngoscopy as a coaching device with standardized coaching language was implemented as a part of practice improvement. All patients in the pediatric intensive care unit were included between January 2016 and December 2017 who underwent primary tracheal intubation with either video laryngoscopy or direct laryngoscopy. The uptake of the implementation, sustained compliance, tracheal intubation outcomes including all adverse tracheal intubation‐associated events, oxygen desaturations (<80% SpO2), and first attempt success were measured. Results: Among 580 tracheal intubations, 284 (49%) were performed during the preimplementation phase, and 296 (51%) postimplementation. Compliance for the use of video laryngoscopy with standardized coaching language was high (74% postimplementation) and sustained. There were no statistically significant differences in adverse tracheal intubation‐associated events between the two phases (pre‐ 9% vs. post‐ 5%, absolute difference −3%, CI95: −8% to 1%, p =.11), oxygen desaturations <80% (pre‐ 13% vs. post‐ 13%, absolute difference 1%, CI95: –6% to 5%, p =.75), or first attempt success (pre‐ 73% vs. post‐ 76%, absolute difference 4%, CI95: –3% to 11%, p =.29). Supervisors were more likely to use the standardized coaching language when video laryngoscopy was used for tracheal intubation than with standard direct laryngoscopy (80% vs. 43%, absolute difference 37%, CI95: 23% to 51%, p <.001). Conclusions: Implementation of video laryngoscopy as a supervising device with standardized coaching language was feasible with high level of adherence, yet not associated with an increased occurrence of any adverse tracheal intubation‐associated events and oxygen desaturation.

Background: Although bereaved parents suffer greatly, some may experience positive change referred to as post-traumatic growth. Objective: Explore the extent to which parents perceive post-traumatic growth after their child's death in a pediatric intensive care unit (PICU), and associated factors. Design: Longitudinal parent survey conducted 6 and 13 months after a child's death. Surveys included the Post-traumatic Growth Inventory-Short Form (PTGI-SF), a 10-item measure with range of 0–50 where higher scores indicate more post-traumatic growth. Surveys also included the Inventory of Complicated Grief (ICG), the Patient Health Questionnaire-8 (PHQ-8) for depression, the Short Post-Traumatic Stress Disorder Rating Interview (SPRINT), a single item on perceived overall health, and sociodemographics. Setting/Subjects: One hundred fifty-seven parents of 104 children who died in 1 of 8 PICUs affiliated with the U.S. Collaborative Pediatric Critical Care Research Network. Results: Of participating parents, 62.4% were female, 71.6% White, 82.7% married, and 89.2% had at least a high school education. Mean PTGI-SF scores were 27.5 ± 12.52 (range 5–50) at 6 months and 28.6 ± 11.52 (range 2–49) at 13 months (p = 0.181). On multivariate modeling, higher education (compared with those not completing high school) and higher 6-month ICG scores (reflecting more complicated grief symptoms) were associated with lower 13-month PTGI-SF scores (p = 0.005 and 0.033, respectively). Conclusion: Parents bereaved by their child's PICU death perceive a moderate degree of post-traumatic growth in the first 13 months after the death however variability is wide. Education level and complicated grief symptoms may influence parents' perception of post-traumatic growth. [ABSTRACT FROM AUTHOR]

BACKGROUND: The association between chest compression (CC) pause duration and pediatric in-hospital cardiac arrest survival outcomes is unknown. The American Heart Association has recommended minimizing pauses in CC in children to <10 seconds, without supportive evidence. We hypothesized that longer maximum CC pause durations are associated with worse survival and neurological outcomes. METHODS: In this cohort study of index pediatric in-hospital cardiac arrests reported in pediRES-Q (Quality of Pediatric Resuscitation in a Multicenter Collaborative) from July of 2015 through December of 2021, we analyzed the association in 5-second increments of the longest CC pause duration for each event with survival and favorable neurological outcome (Pediatric Cerebral Performance Category ≤3 or no change from baseline). Secondary exposures included having any pause >10 seconds or >20 seconds and number of pauses >10 seconds and >20 seconds per 2 minutes. RESULTS: We identified 562 index in-hospital cardiac arrests (median [Q1, Q3] age 2.9 years [0.6, 10.0], 43% female, 13% shockable rhythm). Median length of the longest CC pause for each event was 29.8 seconds (11.5, 63.1). After adjustment for confounders, each 5-second increment in the longest CC pause duration was associated with a 3% lower relative risk of survival with favorable neurological outcome (adjusted risk ratio, 0.97 [95% CI, 0.95–0.99]; P =0.02). Longest CC pause duration was also associated with survival to hospital discharge (adjusted risk ratio, 0.98 [95% CI, 0.96–0.99]; P =0.01) and return of spontaneous circulation (adjusted risk ratio, 0.93 [95% CI, 0.91–0.94]; P <0.001). Secondary outcomes of any pause >10 seconds or >20 seconds and number of CC pauses >10 seconds and >20 seconds were each significantly associated with adjusted risk ratio of return of spontaneous circulation, but not survival or neurological outcomes. CONCLUSIONS: Each 5-second increment in longest CC pause duration during pediatric in-hospital cardiac arrest was associated with lower chance of survival with favorable neurological outcome, survival to hospital discharge, and return of spontaneous circulation. Any CC pause >10 seconds or >20 seconds and number of pauses >10 seconds and >20 seconds were significantly associated with lower adjusted probability of return of spontaneous circulation, but not survival or neurological outcomes.

Introduction: Our objectives are to (1) describe the pathogens, site, timing and risk factors for acquired infection during neonatal and pediatric ECMO and (2) explore the association between acquired infection and mortality. Methods: Secondary analysis of prospective data collected by the Collaborative Pediatric Critical Care Research Network between December 2012 and September 2014. Clinical factors associated with acquired infection were assessed with multivariable Cox regression. Factors associated with mortality were assessed with logistic regression. Results: Of 481 patients, 247 (51.3%) were neonates and 400 (83.2%) received venoarterial ECMO. Eighty (16.6%) patients acquired one or more infections during ECMO; 60 (12.5%) patients had bacterial, 21 (4.4%) had fungal and 11 (2.3%) had viral infections. The site of infection included respiratory for 53 (11.0%) patients, bloodstream for 21 (4.4%), urine for 20 (4.2%) and other for 7 (1.5%). Candida species were most common. Median time to infection was 5.2 days (IQR 2.3, 9.6). On multivariable analysis, a greater number of procedures for ECMO cannula placement was independently associated with increased risk of acquired infection during ECMO (Hazard Ratio 2.13 (95% CI 1.22, 3.72), p<0.01) and receiving ECMO in a neonatal ICU compared to a pediatric or cardiac ICU was associated with decreased risk (Hazard Ratio pediatric ICU 4.25 (95% CI 2.20, 8.20), cardiac ICU 2.91 (95% CI 1.48, 5.71), neonatal ICU as reference, p<0.001). Acquired infection was not independently associated with mortality. Conclusion: ECMO procedures and location may contribute to acquired infection risk; however, acquired infection did not predict mortality in this study. [ABSTRACT FROM AUTHOR]

Background and Aims: The pediatric Critical Illness Stress-induced Immune Suppression (CRISIS) trial compared the effectiveness of 2 nutraceutical supplementation strategies and found no difference in the development of nosocomial infection and sepsis in the overall population. We performed an exploratory post hoc analysis of interaction between nutraceutical treatments and host immune status related to the development of nosocomial infection/sepsis.Methods: Children from the CRISIS trial were analyzed according to 3 admission immune status categories marked by decreasing immune competence: immune competent without lymphopenia, immune competent with lymphopenia, and previously immunocompromised. The comparative effectiveness of the 2 treatments was analyzed for interaction with immune status category.Results: There were 134 immune-competent children without lymphopenia, 79 previously immune-competent children with lymphopenia, and 27 immunocompromised children who received 1 of the 2 treatments. A significant interaction was found between treatment arms and immune status on the time to development of nosocomial infection and sepsis ( P < .05) and on the rate of nosocomial infection and sepsis per 100 patient days ( P < .05). Whey protein treatment protected immune-competent patients without lymphopenia from infection and sepsis, both nutraceutical strategies were equivalent in immune-competent patients with lymphopenia, and zinc, selenium, glutamine, and metoclopramide treatment protected immunocompromised patients from infection and sepsis.Conclusions: The science of immune nutrition is more complex than previously thought. Future trial design should consider immune status at the time of trial entry because differential effects of nutraceuticals may be related to this patient characteristic.

Objectives: To determine the incidence and epidemiologic characteristics of cardiac arrests among tracheal intubations in PICUs.Design: Retrospective cohort study of prospectively collected data.Setting: Twenty-five diverse PICUs.Patients: Critically ill children requiring tracheal intubation in PICUs.Interventions: Tracheal intubation quality improvement data were prospectively collected for all initial tracheal intubations in 25 PICUs from July 2010 to March 2014 using National Emergency Airway Registry for Children registry.Measurements and Main Results: Tracheal intubation-associated cardiac arrest was defined as chest compressions more than 1 minute occurring during tracheal intubation or within 20 minutes after tracheal intubation. A total of 5,232 pediatric tracheal intubations were evaluated. Tracheal intubation-associated cardiac arrest was reported in 87 (1.7%). Patient factors (demographics and indications for tracheal intubation), provider factors (discipline and training level), and practice factors (tracheal intubation method and use of neuromuscular blockade) were recorded. Hemodynamic instability and oxygenation failure as tracheal intubation indications were associated with cardiac arrests (adjusted odds ratio, 6.3; 95% CI, 3.9-10.3; and adjusted odds ratio, 4.3; 95% CI, 2.6-6.9, respectively). History of difficult airway and cardiac disease were also associated with cardiac arrests (adjusted odds ratio, 2.1; 95% CI, 1.2-3.5; and adjusted odds ratio, 2.1; 95% CI, 1.2-3.9, respectively). Provider and practice factors were not associated with cardiac arrests, and provider factors did not modify the effect of patient factors on cardiac arrests.Conclusions: Tracheal intubation-associated cardiac arrests occurred during 1.7% of PICU tracheal intubations. Tracheal intubation-associated cardiac arrests were much more common with tracheal intubations when the child had acute hemodynamic instability or oxygen failure and when the child had a history of difficult airway or cardiac disease.

Objectives: To determine the incidence of cardiopulmonary resuscitation in PICUs and subsequent outcomes.Design, Setting, and Patients: Multicenter prospective observational study of children younger than 18 years old randomly selected and intensively followed from PICU admission to hospital discharge in the Collaborative Pediatric Critical Care Research Network December 2011 to April 2013.Results: Among 10,078 children enrolled, 139 (1.4%) received cardiopulmonary resuscitation for more than or equal to 1 minute and/or defibrillation. Of these children, 78% attained return of circulation, 45% survived to hospital discharge, and 89% of survivors had favorable neurologic outcomes. The relative incidence of cardiopulmonary resuscitation events was higher for cardiac patients compared with non-cardiac patients (3.4% vs 0.8%, p <0.001), but survival rate to hospital discharge with favorable neurologic outcome was not statistically different (41% vs 39%, respectively). Shorter duration of cardiopulmonary resuscitation was associated with higher survival rates: 66% (29/44) survived to hospital discharge after 1-3 minutes of cardiopulmonary resuscitation versus 28% (9/32) after more than 30 minutes (p < 0.001). Among survivors, 90% (26/29) had a favorable neurologic outcome after 1-3 minutes versus 89% (8/9) after more than 30 minutes of cardiopulmonary resuscitation.Conclusions: These data establish that contemporary PICU cardiopulmonary resuscitation, including long durations of cardiopulmonary resuscitation, results in high rates of survival-to-hospital discharge (45%) and favorable neurologic outcomes among survivors (89%). Rates of survival with favorable neurologic outcomes were similar among cardiac and noncardiac patients. The rigorous prospective, observational study design avoided the limitations of missing data and potential selection biases inherent in registry and administrative data.

Background: Externalized ventricular drains (EVDs) are commonly used in pediatric intensive care units (PICU) but few data are available regarding infection rates, infection risks, or factors associated with conversion to permanent cerebrospinal fluid (CSF) diversion. Methods: Retrospective observational study of patients managed with EVDs admitted to a tertiary care PICU from January 2005 to December 2009. Results: Three hundred eighty patients were identified. Neurologic diagnostic groups were externalization of existing shunt in 196 patients (52 %), brain tumor in 122 patients (32 %), intracranial hemorrhage in 23 patients (6 %), traumatic brain injury in 17 patients (5 %), meningitis in 9 patients (2 %), or other in 13 patients (3 %). Six percent of all patients (24/380) had new infections associated with EVD management for an infection rate of 8.6 per 1,000 catheter days. The median time to positive cultures was 7 days (interquartile range 4.75, 9) after EVD placement. Patients with EVD infections had significantly longer EVD duration 6 versus 11.5 days ( p = 0.0001), and higher maximum EVD outputs 1.9 versus 1.5 mL/kg/h ( p = 0.0017). Need for permanent CSF diversion was associated with higher maximum EVD drainage (1.3 vs. 1.6 mL/kg/h p < 0.0001), longer EVD duration (5 vs. 4 days, p < 0.005), and younger age (4.5 vs. 8 years, p < 0.02) but not intracranial hypertension (72 vs. 82 % of patients, p = 0.4). Conclusions: In our large pediatric cohort, EVD infections were associated with longer EVD duration and higher maximum EVD output. Permanent CSF diversion was more likely in patients with higher maximum EVD drainage, longer EVD duration, and younger age. [ABSTRACT FROM AUTHOR]

We hypothesized that the proportion of pediatric cardiopulmonary resuscitation provided in ICUs versus general wards has increased over the past decade, and this shift is associated with improved resuscitation outcomes. Design: Prospective and observational study. Setting: Total of 315 hospitals in the American Heart Association’s Get With The Guidelines-Resuscitation database. Patients: Total of 5,870 pediatric cardiopulmonary resuscitation events between January 1, 2000 and September 14, 2010. Cardiopulmonary resuscitation events were defined as external chest compressions longer than 1 minute. Interventions: None. Measurements and Main Results: The primary outcome was proportion of total ICU versus general ward cardiopulmonary resuscitation events over time evaluated by chi-square test for trend. Secondary outcome included return of spontaneous circulation following the cardiopulmonary resuscitation event. Among 5,870 pediatric cardiopulmonary resuscitation events, 5,477 (93.3%) occurred in ICUs compared to 393 (6.7%) in inpatient wards. Over time, significantly more of these cardiopulmonary resuscitation events occurred in the ICU compared to the wards (test for trend: p < 0.01), with a prominent shift noted between 2003 and 2004 (2000–2003: 87–91% vs 2004–2010: 94–96%). In a multivariable model controlling for within center variability and other potential confounders, return of spontaneous circulation increased in 2004–2010 compared with 2000–2003 (relative risk, 1.08; 95% CI, 1.03–1.13). Conclusions: In-hospital pediatric cardiopulmonary resuscitation is much more commonly provided in ICUs than in wards, and the proportion has increased significantly over the past decade, with concomitant increases in return of spontaneous circulation.

The article discusses a study on the survival trends and neurological disability in children with in-hospital cardiac arrest using data from hospital-based clinical surgery. Study patients were taken from Get With The Guidelines-Resuscitation, a hospital-based clinical registry of in-hospital cardiac arrests that enrolls patients with pulseless cardiac arrest. It suggests improvement in overall survival in children with in-hospital cardiac arrest without higher rates of neurological disability.

OBJECTIVE: The objective of this study was to assess whether pediatric inpatients who receive cardiopulmonary resuscitation (CPR) for bradycardia with poor perfusion are more likely to survive to hospital discharge than pediatric inpatients who receive CPR for pulseless arrest (asystole/pulseless electrical activity [PEA]), after controlling for confounding characteristics. METHODS: A prospective cohort from the National Registry of Cardiopulmonary Resuscitation was enrolled between January 4, 2000, and February 23, 2008. Patients who were younger than 18 years and had an in-hospital event that required chest compressions for >2 minutes were eligible. Patients were divided into 2 groups on the basis of initial rhythm and pulse state: bradycardia/poor perfusion and asystole/PEA. Patient characteristics, event characteristics, and clinical characteristics were analyzed as possible confounders. Univariate analysis between bradycardia and asystole/PEA patient groups was performed. Multivariable logistic regression was used to determine whether an initial state of bradycardia/poor perfusion was independently associated with survival to discharge. RESULTS: A total of 6288 patients who were younger than 18 years were reported; 3342 met all inclusion criteria. A total of 1853 (55%) patients received chest compressions for bradycardia/poor perfusion compared with 1489 (45%) for asystole/PEA. Overall, 755 (40.7%) of 1353 patients with bradycardia survived to hospital discharge, compared with 365 (24.5%) of 1489 patients with asystole/PEA. After controlling for known confounders, CPR for bradycardia with poor perfusion was associated with increased survival to hospital discharge. CONCLUSIONS: Pediatric inpatients with chest compressions initiated for bradycardia and poor perfusion before onset of pulselessness were more likely to survive to discharge than pediatric inpatients with chest compressions initiated for asystole or PEA.

Objectives: This study was designed to compare outcome after adult defibrillation dosing versus pediatric dosing in a piglet model of prolonged prehospital ventricular fibrillation (VF). Background: Weight-based 2 to 4 J/kg monophasic defibrillation dosing is recommended for children in VF, but impractical for automated external defibrillator (AED) use. Present AEDs can only provide adult shock doses or newly developed attenuated adult doses intended for children. A single escalating energy sequence (50/75/86 J) of attenuated adult-dose biphasic shocks (pediatric dosing) is at least as effective as escalating monophasic weight-based dosing for prolonged VF in piglets, but this approach has not been compared to standard adult biphasic dosing. Methods: Following 7 min of untreated VF, piglets weighing 13 to 26 kg (19 ± 1 kg) received either biphasic 50/75/86 J (pediatric dose) or biphasic 200/300/360 J (adult dose) therapies during simulated prehospital life support. Results: Return of spontaneous circulation was attained in 15 of 16 pediatric-dose piglets and 14 of 16 adult-dose piglets. Four hours postresuscitation, pediatric dosing resulted in fewer elevations of cardiac troponin T (0 of 12 piglets vs. 6 of 11 piglets, p = 0.005) and less depression of left ventricular ejection fraction (p < 0.05). Most importantly, more piglets survived to 24 h with good neurologic scores after pediatric shocks than adult shocks (13 of 16 piglets vs. 4 of 16 piglets, p = 0.004). Conclusions: In this model, pediatric shocks resulted in superior outcome compared with adult shocks. These data suggest that adult defibrillation dosing may be harmful to pediatric patients with VF and support the use of attenuating electrodes with adult biphasic AEDs to defibrillate children.

OBJECTIVES: Data to support epinephrine dosing intervals during cardiopulmonary resuscitation (CPR) are conflicting. The objective of this study was to evaluate the association between epinephrine dosing intervals and outcomes. We hypothesized that dosing intervals less than 3 minutes would be associated with improved neurologic survival compared with greater than or equal to 3 minutes. DESIGN: This study is a secondary analysis of The ICU-RESUScitation Project (NCT028374497), a multicenter trial of a quality improvement bundle of physiology-directed CPR training and post-cardiac arrest debriefing. SETTING: Eighteen PICUs and pediatric cardiac ICUs in the United States. PATIENTS: Subjects were 18 years young or younger and 37 weeks old or older corrected gestational age who had an index cardiac arrest. Patients who received less than two doses of epinephrine, received extracorporeal CPR, or had dosing intervals greater than 8 minutes were excluded. INTERVENTIONS: The primary exposure was an epinephrine dosing interval of less than 3 vs. greater than or equal to 3 minutes. MEASUREMENTS AND MAIN RESULTS: The primary outcome was survival to discharge with a favorable neurologic outcome defined as a Pediatric Cerebral Performance Category score of 1-2 or no change from baseline. Regression models evaluated the association between dosing intervals and: 1) survival outcomes and 2) CPR duration. Among 382 patients meeting inclusion and exclusion criteria, median age was 0.9 years (interquartile range 0.3-7.6 yr) and 45% were female. After adjustment for confounders, dosing intervals less than 3 minutes were not associated with survival with favorable neurologic outcome (adjusted relative risk [aRR], 1.10; 95% CI, 0.84-1.46; p = 0.48) but were associated with improved sustained return of spontaneous circulation (ROSC) (aRR, 1.21; 95% CI, 1.07-1.37; p < 0.01) and shorter CPR duration (adjusted effect estimate, -9.5 min; 95% CI, -14.4 to -4.84 min; p < 0.01). CONCLUSIONS: In patients receiving at least two doses of epinephrine, dosing intervals less than 3 minutes were not associated with neurologic outcome but were associated with sustained ROSC and shorter CPR duration.

Objectives: A companion article reports the trajectory of long-term mortality and significant health-related quality of life disability among children encountering septic shock. In this article, the investigators examine critical illness factors associated with these adverse outcomes.Design: Prospective, cohort-outcome study, conducted 2013-2017.Setting: Twelve United States academic PICUs.Patients: Critically ill children, 1 month to 18 years, with community-acquired septic shock requiring vasoactive-inotropic support.Interventions: Illness severity, organ dysfunction, and resource utilization data were collected during PICU admission. Change from baseline health-related quality of life at the month 3 follow-up was assessed by parent proxy-report employing the Pediatric Quality of Life Inventory or the Stein-Jessop Functional Status Scale.Measurements and Main Results: In univariable modeling, critical illness variables associated with death and/or persistent, serious health-related quality of life deterioration were candidates for multivariable modeling using Bayesian information criterion. The most clinically relevant multivariable models were selected among models with near-optimal statistical fit. Three months following septic shock, 346 of 389 subjects (88.9%) were alive and 43 of 389 had died (11.1%); 203 of 389 (52.2%) had completed paired health-related quality of life surveys. Pediatric Risk of Mortality, cumulative Pediatric Logistic Organ Dysfunction scores, PICU and hospital durations of stay, maximum and cumulative vasoactive-inotropic scores, duration of mechanical ventilation, need for renal replacement therapy, extracorporeal life support or cardiopulmonary resuscitation, and appearance of pathologic neurologic signs were associated with adverse outcomes in univariable models. In multivariable regression analysis (odds ratio [95% CI]), summation of daily Pediatric Logistic Organ Dysfunction scores, 1.01/per point (1.01-1.02), p < 0.001; highest vasoactive-inotropic score, 1.02/per point (1.00-1.04), p = 0.003; and any acute pathologic neurologic sign/event, 5.04 (2.15-12.01), p < 0.001 were independently associated with death or persistent, serious deterioration of health-related quality of life at month 3.Conclusions and Relevance: Biologically plausible factors related to sepsis-associated critical illness organ dysfunction and its treatment were associated with poor outcomes at month 3 follow-up among children encountering septic shock.

Objectives: In-hospital pediatric sepsis mortality has decreased substantially, but long-term mortality and morbidity among children initially surviving sepsis, is unknown. Accordingly, the Life After Pediatric Sepsis Evaluation investigation was conducted to describe the trajectory of mortality and health-related quality of life morbidity for children encountering community-acquired septic shock.Design: Prospective, cohort-outcome study, conducted 2013-2017.Setting: Twelve academic PICUs in the United States.Patients: Critically ill children, 1 month to 18 years, with community-acquired septic shock requiring vasoactive-inotropic support.Interventions: Demographic, infection, illness severity, organ dysfunction, and resource utilization data were collected daily during PICU admission. Serial parent proxy-report health-related quality of life assessments were obtained at baseline, 7 days, and 1, 3, 6, and 12 months following PICU admission utilizing the Pediatric Quality of Life Inventory or Stein-Jessop Functional Status Scale.Measurements and Main Results: Among 389 children enrolled, mean age was 7.4 ± 5.8 years; 46% were female; 18% were immunocompromised; and 51% demonstrated chronic comorbidities. Baseline Pediatric Overall Performance Category was normal in 38%. Median (Q1-Q3) Pediatric Risk of Mortality and Pediatric Logistic Organ Dysfunction scores at PICU admission were 11.0 (6.0-17.0) and 9.0 (6.0-11.0); durations of vasoactive-inotropic and mechanical ventilation support were 3.0 days (2.0-6.0 d) and 8.0 days (5.0-14.0 d); and durations of PICU and hospital stay were 9.4 days (5.6-15.4 d) and 15.7 days (9.2-26.0 d). At 1, 3, 6, and 12 months following PICU admission for the septic shock event, 8%, 11%, 12%, and 13% of patients had died, while 50%, 37%, 30%, and 35% of surviving patients had not regained their baseline health-related quality of life.Conclusions: This investigation provides the first longitudinal description of long-term mortality and clinically relevant, health-related quality of life morbidity among children encountering community-acquired septic shock. Although in-hospital mortality was 9%, 35% of survivors demonstrated significant, health-related quality of life deterioration from baseline that persisted at least 1 year following hospitalization for septic shock.

LUNG transplantation , *FUNCTIONAL status , *EXTRACORPOREAL membrane oxygenation , *CYSTIC fibrosis - Abstract
Whether functional status is associated with survival to pediatric lung transplant is unknown. We hypothesized that completely dependent functional status at waitlist registration, defined using Lansky Play Performance Scale (LPPS), would be associated with worse outcomes. Retrospective cohort study of pediatric lung transplant registrants utilizing United Network for Organ Sharing's Standard Transplant Analysis and Research files (2005-2020). Primary exposure was completely dependent functional status, defined as LPPS score of 10-40. Primary outcome was waitlist removal for death/deterioration with cause-specific hazard ratio (CSHR) regression. Subdistribution hazard regression (SHR, Fine and Gray) was used for the secondary outcome of waitlist removal due to transplant/improvement with a competing risk of death/deterioration. Confounders included: sex, age, race, diagnosis, ventilator dependence, extracorporeal membrane oxygenation, year, and listing center volume. A total of 964 patients were included (63.5% ≥ 12 years, 50.2% cystic fibrosis [CF]). Median waitlist days were 95; 20.1% were removed for death/deterioration and 68.2% for transplant/improvement. Completely dependent functional status was associated with removal due to death/deterioration (adjusted CSHR 5.30 [95% CI 2.86-9.80]). This association was modified by age (interaction p = 0.0102), with a larger effect for age ≥12 years, and particularly strong for CF. In the Fine and Gray model, completely dependent functional status did not affect the risk of removal due to transplant/improvement with a competing risk of death/deterioration (adjusted SHR 1.08 [95% CI 0.77-1.49]). Pediatric lung transplant registrants with the worst functional status had worse pretransplant outcomes, especially for adolescents and CF patients. Functional status at waitlist registration may be a modifiable risk factor to improve survival to lung transplant. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives Outcome prediction for pediatric heart surgery has focused on mortality but mortality has been significantly reduced over the past 2 decades. Clinical care practices now emphasize reducing morbidity. Physiology-based profiles assessed by the Pediatric Risk of Mortality (PRISM) score are associated with new significant functional morbidity detected at hospital discharge. Our aims were to assess the relationship between new functional morbidity and surgical risk categories (Risk Adjustment for Congenital Heart Surgery [RACHS] and Society for Thoracic Surgery Congenital Heart Surgery Database Mortality Risk [STAT]), measure the performance of 3-level (intact survival, survival with new functional morbidity, or death) and 2-level (survival or death) PRISM prediction algorithms, and assess whether including RACHS or STAT complexity categories improves the PRISM predictive performance. Methods Patients (newborn to age 18 years) were randomly selected from 7 sites (December 2011-April 2013). Morbidity (using the Functional Status Scale) and mortality were assessed at hospital discharge. The most recently published PRISM algorithms were tested for goodness of fit, and discrimination with and without the RACHS and STAT complexity categories. Results The mortality rate in the 1550 patients was 3.2%. Significant new functional morbidity rate occurred in 4.8%, increasing from 1.8% to 13.9%, 1.7%, and 12.9% from the lowest to the highest RACHS and STAT categories, respectively. The 3-level and 2-level PRISM models had satisfactory goodness of fit and substantial discriminative ability. Inclusion of RACHS and STAT complexity categories did not improve model performance. Conclusions Both mortality and new, functional morbidity are important outcomes associated with surgical complexity and can be predicted using PRISM algorithms. Adding surgical complexity to the physiologic profiles does not improve predictor performance. [ABSTRACT FROM AUTHOR]

Background: Early identification of children at risk for cardiac arrest would allow for skill training associated with improved outcomes and provides a prevention opportunity.Objective: Develop and assess a predictive model for cardiopulmonary arrest using data available in the first 4 h.Methods: Data from PICU patients from 8 institutions included descriptive, severity of illness, cardiac arrest, and outcomes.Results: Of the 10074 patients, 120 satisfying inclusion criteria sustained a cardiac arrest and 67 (55.9%) died. In univariate analysis, patients with cardiac arrest prior to admission were over 6 times and those with cardiac arrests during the first 4 h were over 50 times more likely to have a subsequent arrest. The multivariate logistic regression model performance was excellent (area under the ROC curve = 0.85 and Hosmer-Lemeshow statistic, p = 0.35). The variables with the highest odds ratio's for sustaining a cardiac arrest in the multivariable model were admission from an inpatient unit (8.23 (CI: 4.35-15.54)), and cardiac arrest in the first 4 h (6.48 (CI: 2.07-20.36). The average risk predicted by the model was highest (11.6%) among children sustaining an arrest during hours >4-12 and continued to be high even for days after the risk assessment period; the average predicted risk was 9.5% for arrests that occurred after 8 PICU days.Conclusions: Patients at high risk of cardiac arrest can be identified with routinely available data after 4 h. The cardiac arrest may occur relatively close to the risk assessment period or days later. [ABSTRACT FROM AUTHOR]- Published

Objective: To characterize chest compression (CC) pause duration during the last 5 minutes of pediatric cardiopulmonary resuscitation (CPR) prior to extracorporeal-CPR (E-CPR) cannulation and the association with survival outcomes.Methods: Cohort study from a resuscitation quality collaborative including pediatric E-CPR cardiac arrest events ≥ 10 min with CPR quality data. We characterized CC interruptions during the last 5 min of defibrillator-electrode recorded CPR (prior to cannulation) and assessed the association between the longest CC pause duration and survival outcomes using multivariable logistic regression.Results: Of 49 E-CPR events, median age was 2.0 [Q1, Q3: 0.6, 6.6] years, 55% (27/49) survived to hospital discharge and 18/49 (37%) with favorable neurological outcome. Median duration of CPR was 51 [43, 69] min. During the last 5 min of recorded CPR prior to cannulation, median duration of the longest CC pause was 14.0 [6.3, 29.4] sec: 66% >10 sec, 25% >29 sec, 14% >60 sec, and longest pause 168 sec. Following planned adjustment for known confounders of age and CPR duration, each 5-sec increase in longest CC pause duration was associated with lower odds of survival to hospital discharge [adjusted OR 0.89, 95 %CI: 0.79-0.99] and lower odds of survival with favorable neurological outcome [adjusted OR 0.77, 95 %CI: 0.60-0.98].Conclusions: Long CC pauses were common during the last 5 min of recorded CPR prior to E-CPR cannulation. Following adjustment for age and CPR duration, each 5-second incremental increase in longest CC pause duration was associated with significantly decreased rates of survival and favorable neurological outcome.

Objective: To evaluate the feasibility and perceived benefits of conducting physician-parent follow-up meetings after a child's death in the PICU according to a framework developed by the Collaborative Pediatric Critical Care Research Network. Design: Prospective observational study. Setting: Seven Collaborative Pediatric Critical Care Research Network-affiliated children's hospitals. Subjects: Critical care attending physicians, bereaved parents, and meeting guests (i.e., parent support persons, other health professionals). Interventions: Physician-parent follow-up meetings using the Collaborative Pediatric Critical Care Research Network framework. Measurements and Main Results: Forty-six critical care physicians were trained to conduct follow-up meetings using the framework. All meetings were video recorded. Videos were evaluated for the presence or absence of physician behaviors consistent with the framework. Present behaviors were evaluated for performance quality using a 5-point scale (1 = low, 5 = high). Participants completed meeting evaluation surveys. Parents of 194 deceased children were mailed an invitation to a follow-up meeting. Of these, one or both parents from 39 families (20%) agreed to participate, 80 (41%) refused, and 75 (39%) could not be contacted. Of 39 who initially agreed, three meetings were canceled due to conflicting schedules. Thirty-six meetings were conducted including 54 bereaved parents, 17 parent support persons, 23 critical care physicians, and 47 other health professionals. Physician adherence to the framework was high; 79% of behaviors consistent with the framework were rated as present with a quality score of 4.3 ±0.2. Of 50 evaluation surveys completed by parents, 46 (92%) agreed or strongly agreed the meeting was helpful to them and 40 (89%) to others they brought with them. Of 36 evaluation surveys completed by critical care physicians (i.e., one per meeting), 33 (92%) agreed or strongly agreed the meeting was beneficial to parents and 31 (89%) to them. Conclusions: Follow-up meetings using the Collaborative Pediatric Critical Care Research Network framework are feasible and viewed as beneficial by meeting participants. Future research should evaluate the effects of follow-up meetings on bereaved parents' health outcomes. [ABSTRACT FROM AUTHOR]

VENTRICULAR arrhythmia , *CARDIAC arrest , *VENTRICULAR fibrillation , *VENTRICULAR tachycardia , *HOSPITAL admission & discharge - Abstract
Annually 15,200 children suffer an in-hospital cardiac arrest (IHCA) in the US. Ventricular fibrillation or pulseless ventricular tachycardia (VF/pVT) is the initial rhythm in 10–15% of these arrests. We sought to evaluate the association of number of shocks and early dose escalation with survival for initial VF/pVT in pediatric IHCA. Using 2000–2020 data from the American Heart Association's (AHA) Get with the Guidelines®-Resuscitation (GWTG-R) registry, we identified children >48 hours of life and ≤18 years who had an IHCA from initial VF/pVT and received defibrillation. There were 251 subjects (37.7%) who received a single shock and 415 subjects (62.3%) who received multiple shocks. Baseline and cardiac arrest characteristics did not differ between those who received a single shock versus multiple shocks except for duration of arrest and calendar year. The median first shock dose was consistent with AHA dosing recommendations and not different between those who received a single shock versus multiple shocks. Survival was improved for those who received a single shock compared to multiple shocks. However, no difference in survival was noted between those who received 2, 3, or ≥4 shocks. Of those receiving multiple shocks, no difference was observed with early dose escalation. In pediatric IHCA, most patients with initial VF/pVT require more than one shock. No distinctions in patient or pre-arrest characteristics were identified between those who received a single shock versus multiple shocks. Subjects who received a single shock were more likely to survive to hospital discharge even after adjusting for duration of resuscitation. [ABSTRACT FROM AUTHOR]

Aim: Evaluate cerebrovascular autoregulation (CAR) using near-infrared spectroscopy (NIRS) after pediatric cardiac arrest and determine if deviations from CAR-derived optimal mean arterial pressure (MAPopt) are associated with outcomes.Methods: CAR was quantified by a moving, linear correlation between time-synchronized mean arterial pressure (MAP) and regional cerebral oxygenation, called cerebral oximetry index (COx). MAPopt was calculated using a multi-window weighted algorithm. We calculated burden (magnitude and duration) of MAP less than 5 mmHg below MAPopt (MAPopt - 5), as the area between MAP and MAPopt - 5 curves using numerical integration and normalized as percentage of monitoring duration. Unfavorable outcome was defined as death or pediatric cerebral performance category (PCPC) at hospital discharge ≥3 with ≥1 change from baseline. Univariate logistic regression tested association between burden of MAP less than MAPopt - 5 and outcome.Results: Thirty-four children (median age 2.9 [IQR 1.5,13.4] years) were evaluated. Median COx in the first 24 h post-cardiac arrest was 0.06 [0,0.20]; patients spent 27% [19,43] of monitored time with COx ≥ 0.3. Patients with an unfavorable outcome (n = 24) had a greater difference between MAP and MAPopt - 5 (13 [11,19] vs. 9 [8,10] mmHg, p = 0.01) and spent more time with MAP below MAPopt - 5 (38% [26,61] vs. 24% [14,28], p = 0.03). Patients with unfavorable outcome had a higher burden of MAP less than MAPopt - 5 than patients with favorable outcome in the first 24 h post-arrest (187 [107,316] vs. 62 [43,102] mmHg × Min/Hr; OR 4.93 [95% CI 1.16-51.78]).Conclusions: Greater burden of MAP below NIRS-derived MAPopt - 5 during the first 24 h after cardiac arrest was associated with unfavorable outcomes.

Aims: To determine the prevalence of pulmonary hypertension (PH) among children with in-hospital cardiac arrest (IHCA) and its association with survival.Methods: Children (<18 years) admitted to ICUs participating in the Virtual Pediatric Systems multicenter registry between January 2011 and December 2017 who had an IHCA during their hospitalization were included. Patients were classified by whether they had a documented diagnosis of PH at the time of IHCA. Clinical characteristics were compared between patients with and without PH. After propensity score matching, conditional logistic regression within the matched cohort determined the association between PH and survival to hospital discharge.Results: Of 18,575 children with IHCA during the study period, 1,590 (8.6%) had a pre-arrest diagnosis of PH. Patients with PH were more likely to be 29 days to 2 years of age, female, Black/African American, and American Indian/Alaskan Native, and to be treated in a cardiac ICU or mixed PICU/cardiac ICU. At ICU admission, PH patients had a lower probability of death as determined by the Pediatric Index of Mortality 2 (PIM-2) score. Patients with PH were more likely to be receiving inhaled nitric oxide (13.0% vs. 2.1%; p < 0.001). Propensity score matching successfully matched 1,302 PH patients with 3,604 non-PH patients. Patients with PH were less likely to survive to hospital discharge (aOR 0.83; 95% CI: 0.72-0.95; p = 0.01) than non-PH patients.Conclusions: In this large multicenter study, 8.6% of children with IHCA had pre-existing documented PH. These children were less likely to survive to hospital discharge than those without PH. [ABSTRACT FROM AUTHOR]- Published

Aim: Inhaled nitric oxide (iNO) during cardiopulmonary resuscitation (CPR) improved systemic hemodynamics and outcomes in a preclinical model of adult in-hospital cardiac arrest (IHCA) and may also have a neuroprotective role following cardiac arrest. The primary objectives of this study were to determine if iNO during CPR would improve cerebral hemodynamics and mitochondrial function in a pediatric model of lipopolysaccharide-induced shock-associated IHCA.Methods: After lipopolysaccharide infusion and ventricular fibrillation induction, 20 1-month-old piglets received hemodynamic-directed CPR and were randomized to blinded treatment with or without iNO (80 ppm) during and after CPR. Defibrillation attempts began at 10 min with a 20-min maximum CPR duration. Cerebral tissue from animals surviving 1-h post-arrest underwent high-resolution respirometry to evaluate the mitochondrial electron transport system and immunohistochemical analyses to assess neuropathology.Results: During CPR, the iNO group had higher mean aortic pressure (41.6 ± 2.0 vs. 36.0 ± 1.4 mmHg; p = 0.005); diastolic BP (32.4 ± 2.4 vs. 27.1 ± 1.7 mmHg; p = 0.03); cerebral perfusion pressure (25.0 ± 2.6 vs. 19.1 ± 1.8 mmHg; p = 0.02); and cerebral blood flow relative to baseline (rCBF: 243.2 ± 54.1 vs. 115.5 ± 37.2%; p = 0.02). Among the 8/10 survivors in each group, the iNO group had higher mitochondrial Complex I oxidative phosphorylation in the cerebral cortex (3.60 [3.56, 3.99] vs. 3.23 [2.44, 3.46] pmol O2/s mg; p = 0.01) and hippocampus (4.79 [4.35, 5.18] vs. 3.17 [2.75, 4.58] pmol O2/s mg; p = 0.02). There were no other differences in mitochondrial respiration or brain injury between groups.Conclusions: Treatment with iNO during CPR resulted in superior systemic hemodynamics, rCBF, and cerebral mitochondrial Complex I respiration in this pediatric cardiac arrest model.

Develop a novel, physiology-based measurement of duty cycle (Arterial Blood Pressure–Area Duty Cycle [ABP–ADC]) and evaluate the association of ABP–ADC with intra-arrest hemodynamics and patient outcomes. This was a secondary retrospective study of prospectively collected data from the ICU-RESUS trial (NCT02837497). Invasive arterial waveform data were used to derive ABP–ADC. The primary exposure was ABP–ADC group (<30%; 30–35%; >35%). The primary outcome was systolic blood pressure (sBP). Secondary outcomes included intra-arrest physiologic goals, CPR quality targets, and patient outcomes. In an exploratory analysis, adjusted splines and receiver operating characteristic (ROC) curves were used to determine an optimal ABP–ADC associated with improved hemodynamics and outcomes using a multivariable model. Of 1129 CPR events, 273 had evaluable arterial waveform data. Mean age is 2.9 years + 4.9 months. Mean ABP–ADC was 32.5% + 5.0%. In univariable analysis, higher ABP–ADC was associated with lower sBP (p < 0.01) and failing to achieve sBP targets (p < 0.01). Other intra-arrest physiologic parameters, quality metrics, and patient outcomes were similar across ABP–ADC groups. Using spline/ROC analysis and clinical judgement, the optimal ABP–ADC cut point was set at 33%. On multivariable analysis, sBP was significantly higher (point estimate 13.18 mmHg, CI95 5.30–21.07, p < 0.01) among patients with ABP–ADC < 33%. Other intra-arrest physiologic and patient outcomes were similar. In this multicenter cohort, a lower ABP–ADC was associated with higher sBPs during CPR. Although ABP–ADC was not associated with outcomes, further studies are needed to define the interactions between CPR mechanics and intra arrest patient physiology. [ABSTRACT FROM AUTHOR]

GLOBAL longitudinal strain , *CARDIAC arrest , *CONGENITAL heart disease , *ECHOCARDIOGRAPHY , *PEDIATRIC intensive care - Abstract
Global longitudinal strain (GLS) is an echocardiographic method to identify left ventricular (LV) dysfunction after cardiac arrest that is less sensitive to loading conditions. We aimed to identify the frequency of impaired GLS following pediatric cardiac arrest, and its association with hospital mortality. This is a retrospective single-center cohort study of children <18 years of age treated in the pediatric intensive care unit (PICU) after in- or out-of-hospital cardiac arrest (IHCA and OHCA), with echocardiogram performed within 24 hours of initiation of post-arrest PICU care between 2013 and 2020. Patients with congenital heart disease, post-arrest extracorporeal support, or inability to measure GLS were excluded. Echocardiographic LV ejection fraction (EF) and shortening fraction (SF) were abstracted from the chart. GLS was measured post hoc; impaired strain was defined as LV GLS ≥ 2 SD worse than age-dependent normative values. Demographics and pre-arrest, arrest, and post-arrest characteristics were compared between subjects with normal versus impaired GLS. Correlation between GLS, SF and EF were calculated with Pearson comparison. Logistic regression tested the association of GLS with mortality. Area under the receiver operator curve (AUROC) was calculated for discriminative utility of GLS, EF, and SF with mortality. GLS was measured in 124 subjects; impaired GLS was present in 46 (37.1%). Subjects with impaired GLS were older (median 7.9 vs. 1.9 years, p < 0.001), more likely to have ventricular tachycardia/fibrillation as initial rhythm (19.6% versus 3.8%, p = 0.017) and had higher peak troponin levels in the first 24 hours post-arrest (median 2.5 vs. 0.5, p = 0.002). There were no differences between arrest location or CPR duration by GLS groups. Subjects with impaired GLS compared to normal GLS had lower median EF (42.6% versus 62.3%) and median SF (23.3% versus 36.6%), all p < 0.001, with strong inverse correlation between GLS and EF (rho −0.76, p < 0.001) and SF (rho −0.71, p < 0.001). Patients with impaired GLS had higher rates of mortality (60% vs. 32%, p = 0.009). GLS was associated with mortality when controlling for age and initial rhythm [aOR 1.17 per 1% increase in GLS (95% CI 1.09–1.26), p < 0.001]. GLS, EF and SF had similar discrimination for mortality: GLS AUROC 0.69 (95% CI 0.60–0.79); EF AUROC 0.71 (95% CI 0.58–0.88); SF AUROC 0.71 (95% CI 0.61–0.82), p = 0.101. Impaired LV function as measured by GLS after pediatric cardiac arrest is associated with hospital mortality. GLS is a novel complementary metric to traditional post-arrest echocardiography that correlates strongly with EF and SF and is associated with mortality. Future large prospective studies of post-cardiac arrest care should investigate the prognostic utilities of GLS, alongside SF and EF. [ABSTRACT FROM AUTHOR]

Background: Cardiopulmonary resuscitation (CPR) is initiated in hospitalized children with bradycardia and poor perfusion. However, their rate of progression to pulseless cardiac arrest despite CPR and the differences in survival compared with initially pulseless arrest are unknown. We examined the prevalence and predictors of survival of children who progress from bradycardia to pulseless in-hospital cardiac arrest despite CPR.Methods: Pediatric patients >30 days and <18 years of age who received CPR at hospitals participating in Get With The Guidelines-Resuscitation during 2000 to 2016 were included. Each CPR event was classified as bradycardia with pulse, bradycardia with subsequent pulselessness, and initial pulseless cardiac arrest. We assessed risk-adjusted rates of survival to hospital discharge using multilevel Poisson regression models.Results: Overall, 5592 pediatric patients were treated with CPR, of whom 2799 (50.1%) received CPR for bradycardia with poor perfusion and 2793 (49.9%) for initial pulseless cardiac arrest. Among those with bradycardia, 869 (31.0%, or 15.5% of cohort) became pulseless after a median of 3 minutes of CPR (interquartile range, 1-9 minutes). Rates of survival to discharge were 70.0% (1351 of 1930) for bradycardia with pulse, 30.1% (262 of 869) for bradycardia progressing to pulselessness, and 37.5% (1046 of 2793) for initial pulseless cardiac arrest (P for difference across groups <0.001). Children who became pulseless despite CPR for bradycardia had a 19% lower likelihood (risk ratio, 0.81 [95% CI, 0.70, 0.93]; P=0.004) of surviving to hospital discharge than those who were initially pulseless. Among children who progressed to pulselessness despite CPR for bradycardia, a longer interval between CPR and pulselessness was a predictor of lower survival (reference, <2 minutes; for 2-5 minutes, risk ratio, 0.54 [95% CI, 0.41-0.70]; for >5 minutes, risk ratio, 0.41 [95% CI, 0.32-0.53]).Conclusions: Among hospitalized children in whom CPR is initiated, half have bradycardia with poor perfusion at the initiation of chest compressions, and nearly one-third of these progress to pulseless in-hospital cardiac arrest despite CPR. Survival was significantly lower for children who progress to pulselessness despite CPR compared with those who were initially pulseless. These findings suggest that pediatric patients who lose their pulse despite resuscitation attempts are at particularly high risk and require a renewed focus on postresuscitation care.

Animal studies have established deleterious hemodynamic effects of interrupting chest compressions. The objective of this study was to evaluate the effect of interruptions on invasively measured blood pressures (BPs) during pediatric in-hospital cardiac arrest (IHCA). This was a single-center, observational study of pediatric (<18 years) intensive care unit IHCAs in patients with invasive arterial catheters in place. Interruptions were defined as ≥1 s between chest compressions. Diastolic BP (DBP) and systolic BP (SBP) were determined for individual compressions. For the primary analysis, the average DBP and SBP of the 20 compressions preceding each interruption were compared to the average DBP and SBP of the first 20 compressions following each interruption utilizing non-parametric paired analyses. Linear regression evaluated the change in DBP during interruptions and following interruptions. Thirty-two IHCA events met inclusion criteria, yielding 161 evaluable interruptions. The median age was 2.1 years. Return of circulation was achieved in 24 (75%). The median interruption duration was 2.4 [1.4, 7.0] seconds. Most patients were intubated pre-arrest and received epinephrine during CPR. BPs were not different pre- vs. post-interruption (DBP: 28.7 [21.6, 38.2] vs. 28.3 [21.0, 37.4] mmHg, p = 0.81; SBP: 82.0 [51.7, 116.7] vs. 85.4 [55.7, 122.2] mmHg, p = 0.07). DBP decreased 8.41 ± 0.73 mmHg (p < 0.001) during the first second of interruptions and 0.19 ± 0.02 mmHg/s (p < 0.001) in subsequent seconds. BPs following chest compression interruptions did not differ from pre-interruption BPs. These findings suggest that in the setting of high-quality in-hospital CPR, brief chest compression interruptions do not have persistent detrimental hemodynamic impact. [ABSTRACT FROM AUTHOR]

Aim: The primary aim of this study was to evaluate the association between chest compression rates and 1) arterial blood pressure and 2) survival outcomes during pediatric in-hospital cardiopulmonary resuscitation (CPR).Methods: Prospective observational study of children ≥37 weeks gestation and <19 years old who received CPR in an intensive care unit (ICU) as part of the Pediatric Intensive Care Unit Quality of CPR Study (PICqCPR) of the Collaborative Pediatric Critical Care Research Network (CPCCRN). Arterial blood pressure and compression rate were determined from manually extracted arterial line waveform data during the first 10 min of CPR. The primary outcome was survival to hospital discharge. Modified Poisson regression models assessed the association between rate categories (80-<100, 100-120 [Guidelines], >120-140, >140) and outcomes.Results: Compression rate data were available for 164 patients. More than half (98/164; 60%) were <1 year old. Return of circulation was achieved in 148/164 (90%); survival to hospital discharge in 77/164 (47%). Percentage of events with average rate within Guidelines was 32.9%. Compared to Guidelines, higher rate categories were associated with lower systolic blood pressures (>120-140, p = 0.010; >140, p = 0.077), but not survival. A rate between 80-<100 per minute was associated with a higher rate of survival to hospital discharge (aRR 1.92, CI95 1.13, 3.29, p = 0.017) and survival with favorable neurological outcome (aRR 2.12, CI95 1.09, 4.13, p = 0.027) compared to Guidelines.Conclusion: Non-compliance with compression rate Guidelines was common in this multicenter cohort. Among ICU patients, slightly lower rates were associated with improved outcomes compared to Guidelines. [ABSTRACT FROM AUTHOR]- Published
