OBJECTIVE While the surgical stages of single ventricle (SV) palliation serve to separate pulmonary venous and systemic venous return, and to volume-unload the SV, staged palliation also results in transition from parallel to series circulation, increasing total vascular resistance. How this transition affects pressure loading of the SV is as yet unreported. METHODS We performed a retrospective chart review of Stage I, II, and III cardiac catheterization (CC) and echocardiographic data from 2001-2017 in all SV pts, with focus on systemic, pulmonary, and total vascular resistance (SVR, PVR, TVR respectively). Longitudinal analyses were performed with log-transformed variables. Effects of SVR-lowering medications were analyzed using Wilcoxon rank-sum testing. RESULTS There were 372 total patients who underwent CC at a Stage I (median age of 4.4 months, n=310), Stage II (median age 2.7 years, n = 244), and Stage III (median age 7.3 years, n = 113). Total volume loading decreases with progression to Stage III (P< 0.001). While PVR gradually increases from Stage II to Stage III, and SVR increases from Stage I to Stage III, TVR dramatically increases with progress towards series circulation. TVR was not affected by use of systemic vasodilator therapy. TVR, PVR, SVR, and CI did not correlate with indices of SV function at Stage III. CONCLUSIONS TVR steadily increases with an increasing contribution from SVR over progressive stages. TVR was not affected by systemic vasodilator agents. TVR did not correlate with echo-based indices of SV function. Further studies are needed to see if modulating TVR can improve exercise tolerance and outcomes.

Magnetic resonance imaging (MRI) is the most common imaging procedure requiring sedation/anesthesia in children. Understanding adverse events associated with sedation/anesthesia is important in making decisions regarding MRI vs. other imaging modalities. No large studies have evaluated the practice of pediatric sedation/anesthesia for MRI by a variety of pediatric specialists.Utilize a large pediatric sedation database to characterize the patients and adverse events associated with sedation/anesthesia for pediatric MRI.Retrospective analysis of prospectively collected data.The Pediatric Sedation Research Consortium (PSRC) has 109,947 entries for sedations for MRI from November 10, 2011 through December 18, 2017.Patient demographics, sedative medications, interventions, and adverse events are described. Associations with adverse events were assessed. Trends in sedative medications used over time are examined.Descriptive statistics, Chi-Squared and Fisher's Exact tests for categorical variables, logistic regression and assessment of trend using logistic regression and other method.A total of 109,947 MRI-related sedations were examined. Most subjects (66.2%) were 5 years old or younger. Seizure or other neurologic issue prompted MRI in 63.7% of cases. Providers responsible for sedation/anesthesia included intensivists (49.3%), emergency medicine physicians (28.2%), hospitalists (10.2%), and anesthesiologists (9.8%). The most commonly used sedative agent was propofol (89.1%). The most common airway intervention was supplemental oxygen (71.7%), followed by head/airway repositioning (20.6%). Airway-related adverse events occurred in 8.4% of patients. Serious adverse events occurred in only 0.06% of patients, including three cases of cardiac arrest. No mortality was recorded. There was a statistically significant increase in the use of dexmedetomidine over time.Overall, adverse event rates were low. Sedation/anesthesia with propofol infusion and natural airway was the most common method used by this varied group of sedation providers. The use of dexmedetomidine increased over time.4 TECHNICAL EFFICACY: Stage 5.

OBJECTIVE: Standardized pain assessment and interventions are recommended for youth hospitalized for pain. This quality improvement (QI) project integrated into a pediatric psychology service aimed to increase the standardized assessment of pain-related functional ability for youth with sickle cell disease (SCD) hospitalized for pain. METHODS: Children and adolescents (n=102) with SCD referred for psychology consultation for poor coping in response to pain during hospitalization completed a validated self-report of functional ability in addition to pain intensity during inpatient psychology visits. At the time of the quality initiative, routine and standardized assessment of pain-related functional ability was not integrated into standard clinical care. Plan, Do, Study, Act (PDSA) cycles determined the feasibility and addressed common barriers of routine assessment and documentation of pain-related functional ability among youth with SCD during inpatient psychology visits with the primary goal to increase assessment of functional ability to at least 85% among patients with SCD referred for pediatric psychology consultation to address pain management within 1 year. RESULTS: Through iterative PDSA cycles, routine assessment of pain-related functional ability during psychology visits increased to an average of 93% over the course of 12 months. Routine, standardized assessment of functional ability was considered feasible within a pediatric psychology service. CONCLUSIONS/LESSONS LEARNED: This project supported the feasibility of integrating standardized assessment of functional ability to enhance pain assessment for youth hospitalized for SCD pain as part of routine clinical care in a multidisciplinary setting regardless of psychology referral.

Objective: Pediatric oncology nurses can experience burnout, vicarious traumatization, and compassion fatigue related to the unique stressors of their profession. Opportunities to enhance nurses’ professional commitment and nurse–patient connectedness may mitigate these stressors. This study explored the impact of volunteering at a local oncology camp on pediatric oncology nurses’ professional quality of life and connectedness with their oncology patients. Method and Sample: Pediatric oncology nurses from a single institution were invited to participate in this mixed methods study. Participants completed a survey assessing professional quality of life, professional commitment, and patient connectedness. Nurses who had oncology camp volunteer experience were invited to participate in a qualitative interview. Results: Compared with noncamp nurses ( n = 23), camp nurses ( n = 25) had increased odds of a low burnout score (odds ratio = 6.74, 95% confidence interval [1.10, 41.43], p = .039) and increased odds of a high compassion satisfaction score (odds ratio = 4.69, 95% confidence interval [1.14, 19.32], p = .033). Qualitative interviews supported the impact of volunteering at camp on nurses’ personal and professional perspective, nursing practice, and delivery of person-centered care. Conclusion: Volunteering at a pediatric oncology camp provided nurses the opportunity to engage with patients, share experiences, and view patients as individuals while still maintaining professional boundaries. Nurses who volunteer at camp described a perspective moving beyond patient-centered to person-centered care, and for some pediatric oncology nurses, camp volunteering may be a novel way to mitigate burnout and an important tool to enhance resiliency.

Purpose The aim of this study was to determine long-term outcomes for congenital diaphragmatic hernia (CDH) patients including quality of life (QoL), symptom burden, reoperation rates, and health status. Methods A chart review and phone QoL survey were performed for patients who underwent CDH repair between 2007 and 2014 at a tertiary free-standing children’s hospital. Comprehensive outcomes were collected including subsequent operations and health status. Associations with QoL were tested using Wilcoxon Rank-Sum tests and Pearson correlation coefficients. Results Of 102 CDH patients identified, 46 (45.1%) patient guardians agreed to participate with mean patient age of 5.8 (SD, 2.2) years at time of follow-up. Median PedsQLTM and PedsQLTM Gastrointestinal scores were 91.8 (IQR, 84.8–95.8) and 95.8 (IQR, 93.0–98.2), out of 100. Thoracoscopic repair was associated with higher PedsQLTM scores while defects with an intrathoracic stomach were associated with increased gas and bloating. No difference in QoL was found when comparing defect side, patch vs primary repair, prenatal diagnosis, extracorporeal membrane oxygenation, or recurrence. Older age weakly correlated with worse school functioning and heartburn. Conclusion Children with CDH have reassuring QoL scores. Given the correlation between older age and poor school function, longer follow-up of patients with CDH may be warranted. Level of Evidence III (Retrospective comparative study).

Neonates with intestinal atresia (IA) undergo either primary anastomosis (PA) or ostomy creation with secondary anastomosis (SA). Our purpose was to compare outcomes for PA and SA and to assess factors influencing procedure selection.We conducted a retrospective cohort study of neonates with IA between 2009 and 2015. Patient characteristics, operative details, and outcomes were collected. Surgeon-level preferences (defined as performing50% PA or SA) were assessed using logistic regression.Of 92 IA patients, 70 (76.1%) underwent PA and 22 (23.9%) underwent SA. Neonates with PA had shorter hospitalizations (27 days vs. 95 days, p 0.001), shorter total parenteral nutrition duration (19 days vs. 74.5 days, p 0.001), and fewer readmissions (33.3% vs. 63.2%, p = 0.024). On multivariable regression analysis, higher Apgar scores (Odds Ratio (OR) 4.16, 95% Confidence Interval (CI) 1.20-14.29) and uncomplicated atresia (OR 3.97, 95% CI 1.37-11.48) were associated with PA. At the surgeon-level, utilization of PA varied from 43.5% to 100%. Surgeon preference is not influenced by the demographic, presentation, or surgical findings of this patient population.PA has better outcomes than SA. Though procedural selection is influenced by the clinical status of the neonate, however surgeon preference plays a significant role in this clinical decision.Level III Treatment Study.

OBJECTIVES: The evolving role of children’s hospitals (CHs) in the setting of rising health care costs has not been fully explored. We compared pediatric inpatient discharge volumes and costs by hospital type and examined the impact of care complexity and hospital-level factors on costs. METHODS: A retrospective, cross-sectional study of care between 2000 and 2009 was performed by using the Kids’ Inpatient Database. Weighted discharge data were used to generate national estimates for a comparison of inpatient volume, cost, and complexity at CHs and nonchildren’s hospitals (NCHs). Linear regression was used to assess how complexity, payer mix, and hospital-level characteristics affected inflation-adjusted costs. RESULTS: Between 2000 and 2009, the number of discharges per 1000 children increased from 6.3 to 7.7 at CHs and dropped from 55.4 to 53.3 at NCHs. The proportion of discharges at CHs grew by 6.8% between 2006 and 2009 alone. In 2009, CHs were responsible for 12.6% (95% confidence interval: 10.4%–14.9%) of pediatric discharges and 14.7% of major therapeutic procedures, yet they accounted for 23.0% of inpatient costs. Costs per discharge were significantly higher at CHs than at NCHs for all years (P < .001); however, the increase in costs seen over time was not significant. Care complexity increased during the study period at both CHs and NCH, but it could not be used to fully account for the difference in costs. CONCLUSIONS: National trends reveal a small rise in both the proportion of inpatient discharges and the hospital costs at CHs, with costs being significantly higher at CHs than at NCHs. Research into factors influencing costs and the role of CHs is needed to inform policy and contain costs.

OBJECTIVE: To determine risk factors associated with admission to a pediatric intensive care unit (PICU) with or without endotracheal intubation for an asthma exacerbation. We hypothesized that children with critical and near-fatal asthma would have distinguishing clinical features but varying degrees of asthma severity and measures of type 2 inflammation. DESIGN: Retrospective analysis of prospectively collected data of children with asthma recruited into outpatient asthma clinical research studies at Emory University between 2004 and 2015. SETTING: Large, free-standing academic quaternary care children’s hospital in Atlanta, Georgia. PATIENTS: Children 6 to 18 years of age with physician-diagnosed and confirmed asthma. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 579 children were analyzed with 170 (29.4%) children being admitted to the PICU for an asthma exacerbation in their lifetime. Of these 170 children with a history of critical asthma, 24.1% were classified as having mild-to-moderate asthma, and 83/170 children (48.8%) had been intubated and experienced near-fatal asthma. Multiple logistic regression was used to identify risk factors associated with increased odds of PICU admission with or without endotracheal intubation. Hospitalization within the prior 12-months of survey (odds ratio (OR): 8.19, 95% confidence interval (CI): 4.83–13.89), a history of pneumonia (OR: 2.56, 95% CI: 1.52–4.29), having a designation of increased chronic asthma severity on high-dose inhaled corticosteroids (OR: 2.76, 95% CI: 1.62–4.70), having a father with asthma (OR: 2.15, 95% CI: 1.23–3.76), living in a region with a higher burden of poverty (OR: 1.28, 95% CI: 1.02–1.61), and being of black race (OR: 2.01, 95% CI: 1.05–3.84) were all associated with increased odds of PICU admission with or without intubation. CONCLUSIONS: Our findings suggest that there are factors associated with critical and near-fatal asthma, distinct from the chronic asthma severity designations, that should be the focus of future investigation.

INTRODUCTION This study describes the experience at a level 1 pediatric trauma center before and after the centralization of prehospital trauma triage, focusing on the rate of undertriage of trauma patients. Before centralization, emergency physicians were responsible for triaging these patients with mainly physiology-based criteria; after centralization, paramedics in a communication center performed this function using the same criteria. METHODS This retrospective study includes 10 years of pediatric trauma registry patients at our institution, 5 years before and after centralization of prehospital triage. Rates of undertriage were calculated by both the Cribari Method and by disposition from the emergency department. Logistic regression was used to assess the effect of centralization on the incidence of undertriage while adjusting for differences in case-mix. RESULTS Over the 10-year study period, 1862 trauma activations meeting inclusion and exclusion criteria were recorded in the trauma registry: 893 patients in the precentralization and 969 in the postcentralization groups. After centralization of the triage process, there were statistically significant decreases in the rates of undertriage from 8.7% to 4.2% (adjusted odds ratio, 0.49; 95% confidence interval, 0.33-0.73) when analyzed by the Cribari Method and from 37.7% to 27.7% when analyzed by disposition from the emergency department (adjusted odds ratio, 0.66; 95% confidence interval, 0.64-0.81). This represents a reduction in undertriage by 51.7% and 26.5%, respectively. CONCLUSIONS Centralization of prehospital trauma triage at a level 1 pediatric trauma facility significantly reduced undertriage rates. Trauma centers should consider similar processes to improve prehospital triage.

BACKGROUND In patients with pulmonary atresia, intact ventricular septum (PA/IVS) following right ventricular (RV) decompression, RV size and morphology drive clinical outcome. Our objectives were to (1) identify baseline and postdecompression echocardiographic parameters associated with 2V circulation, (2) identify echocardiographic parameters associated with RV growth and (3) describe changes in measures of RV size and changes in RV loading conditions. METHODS We performed a retrospective analysis of patients who underwent RV decompression for PA/IVS at four centers. We analyzed echocardiograms at baseline, postdecompression, and at follow up (closest to 1-year or prior to Glenn circulation). RESULTS Eighty-one patients were included. At last follow-up, 70 (86%) patients had 2V circulations, 7 (9%) had 1.5 ventricle circulations, and 4 (5%) had single ventricle circulations. Follow-up echocardiograms were available in 43 (53%) patients. The majority of patients had improved RV systolic function, less tricuspid regurgitation (TR), and more left-to-right atrial shunting at a median of 350 days after decompression. Multivariable analysis demonstrated that larger baseline tricuspid valve (TV) z-score (P = .017), ≥ moderate baseline TR (P = .045) and smaller baseline RV area (P

To assess MUC5AC as a biomarker for respiratory syncytial virus (RSV) disease severity, we tested nasal aspirates from RSV+ children with mild, moderate, and severe disease. Levels were significantly higher in those in the severe and moderate groups compared to mild group, indicating MUC5AC may be a useful biomarker for RSV disease severity.

Enhanced recovery protocols (ERPs) have been shown to improve outcomes in adult surgical populations. Our purpose was to compare outcomes before and after implementation of an ERP in children undergoing elective colorectal surgery.A pediatric-specific colorectal ERP was developed and implemented at a single center starting in January 2015. A retrospective review was performed including 43 patients in the pre-ERP period (2012-2014) and 36 patients in the post-ERP period (2015-2016). Outcomes of interest included number of ERP interventions received, length of stay (LOS), complications, and readmissions.The median number of ERP interventions received per patient increased from 5 to 11 from 2012 to 2016. The median LOS decreased from 5days to 3days in the post-ERP period (p=0.01). We observed a simultaneous decrease in median time to regular diet, mean dose of narcotics, and mean volume of intraoperative fluids (p0.001). The complication rate (21% vs. 17%, p=0.85) and 30-day readmission rate (23% vs. 11%, p=0.63) were not significantly different in the pre- and post-ERP periods.Implementation of a pediatric-specific ERP in children undergoing colorectal surgery is feasible, safe and may lead to improved outcomes. Further experience may highlight other opportunities for increased compliance and improved care.Treatment Study. Level III.

Background Our goal is to determine short- and long-term outcomes of simple gastroschisis (SG) and complicated gastroschisis (CG) patients including quality of life (QoL) measures, surgical reoperation rates, and residual gastrointestinal symptom burden. Materials and methods Retrospective chart review of patients who underwent surgical repair of gastroschisis between January 1, 2009, and December 31, 2012, was performed at a quaternary children's hospital. Parent telephone surveys were conducted to collect information on subsequent operations and current health status as well as to assess QoL using two validated tools. Results Of 143 patients identified, 45 (31.5%) were reached and agreed to participate with a median follow-up age of 4.7 y. Although CG was associated with short-term outcomes such as longer length of stay, longer days to feeds, and higher complication rates, there were no major differences in long-term QoL outcomes when comparing SG and CG. Children with CG experienced abdominal pain/gas/diarrhea more often than those with SG and required more major abdominal procedures than those with SG (15% versus 0%, P = 0.009). Conclusions Despite worse short-term outcomes, presence of certain gastrointestinal symptoms, and need for more surgical interventions for patients with CG, and overall QoL scores were reassuringly similar to those with SG.

OBJECTIVE To derive and validate clinical prediction models to identify children at low risk of clinically significant intoxications for whom intensive care admission is unnecessary. DESIGN Retrospective review of data in the National Poison Data Systems from 2011 to 2014 and Georgia Poison Center cases from July to December 2016. SETTING United States PICUs and poison centers participating in the American Association of Poison Control Centers from 2011 to 2016. PATIENTS Children 18 years and younger admitted to a United States PICU following an acute intoxication. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary study outcome was the occurrence of clinically significant intoxications defined a priori as organ system-based clinical effects that require intensive care monitoring and interventions. We analyzed 70,364 cases. Derivation (n = 42,240; 60%) and validation cohorts (n = 28,124; 40%) were randomly selected from the eligible population and had similar distributions of clinical effects and PICU interventions. PICU interventions were performed in 1,835 children (14.1%) younger than 6 years, in 374 children (15.4%) 6-12 years, and in 4,446 children (16.5%) 13 years and older. We developed highly predictive models with an area under the receiver operating characteristic curve of 0.834 (< 6 yr), 0.771 (6-12 yr), and 0.786 (≥13 yr), respectively. For predicted probabilities of less than or equal to 0.10 in the validation cohorts, the negative predictive values were 95.4% (< 6 yr), 94.9% (6-12 yr), and 95.1% (≥ 13 yr). An additional 700 patients from the Georgia Poison Center were used to validate the model and would have reduced PICU admission by 31.4% (n = 110). CONCLUSIONS These validated models identified children at very low risk of clinically significant intoxications for whom pediatric intensive care admission can be avoided. Application of this model using Georgia Poison Center data could have resulted in a 30% reduction in PICU admissions following intoxication.

In September 2011 the AAP (American Academy of Pediatrics) released updated guidelines for the evaluation of children 2 to 24 months old with a febrile urinary tract infection. We documented the impact of the guideline on diagnosis and surgical management of vesicoureteral reflux at U.S. children's hospitals. We hypothesized that voiding cystourethrogram studies and the vesicoureteral reflux treatment rate decreased concurrent with the national guideline release.The Pediatric Health Information System was queried for children (younger than 18 years) with primary vesicoureteral reflux and their antireflux surgical history from January 2004 to June 2015. Voiding cystourethrogram orders were recorded. Interrupted time series analysis quantified trends surrounding several seminal vesicoureteral reflux publications (2007) and guideline publication (2011).A total of 43,341 voiding cystourethrogram encounters (male 23,946 [55.3%]) were identified for patients at a median age of 3 months (IQR 1-20). For all children monthly voiding cystourethrogram orders increased (+1.0 to +1.6 encounters per month, p0.034) to September 2011, then sharply declined by 106 encounters per month from September to October 2011 (p0.001) then did not change significantly (p=0.096, RThe number of voiding cystourethrograms ordered nationally in all children and those with a urinary tract infection decreased sharply with the 2011 AAP urinary tract infection guideline release and did not change thereafter. A steady decline in procedures for primary vesicoureteral reflux occurred after October 2011.

Peripheral intravenous (PIV) cannulation needed for pediatric procedural sedation (PPS) is a common source of stress for patients and families. The goal of this project is to investigate the perceived effectiveness of nitrous oxide (N 2 O) in reducing anxiety and pain associated with PIV cannulation for PPS by various stakeholders. N 2 O was used as an adjunct to local anesthesia and child life intervention to reduce the anxiety and pain associated with PIV placement before PPS. N 2 O use was at the discretion of physician. Candidates included patients who were anxious or fearful about PIV placement or patients who had a failed prior PIV cannulation attempt without N 2 O. At the completion of the procedure, a survey was administered to determine stakeholder satisfaction with N 2 O for PIV cannulation. A total of 393 N 2 O sedations for PIV cannulation were identified. Overall, procedure success was 96.2%. Most stakeholders reported that they were very satisfied: physicians—341/382 (89.3%), nurses—350/380 (92.1%), parents—347/383 (90.6%), and patients—331/377 (87.8%). Overall patient-parent agreement about N 2 O satisfaction was 94.1%. The most common adverse events (AEs) seen were dysphoria—11/393 (2.8%) and vomiting—5/393 (1.3%). None of the patients required prolonged stay for AE. N 2 O can be successfully used for PIV cannulation for PPS without clinically significant AE and has a high degree of satisfaction among the stakeholders. N 2 O should be considered as a method to reduce anxiety and pain in patients requiring PIV cannulation and those subjected to repeated procedures.

OBJECTIVES Outcomes associated with a sedative regimen comprised ketamine + propofol for pediatric procedural sedation outside of both the pediatric emergency department and operating room are underreported. We used the Pediatric Sedation Research Consortium database to describe a multicenter experience with ketamine + propofol by pediatric sedation providers. DESIGN Prospective observational study of children receiving IV ketamine + propofol for procedural sedation outside of the operating room and emergency department using data abstracted from the Pediatric Sedation Research Consortium during 2007-2015. SETTING Procedural sedation services from academic, community, free-standing children's hospitals, and pediatric wards within general hospitals. PATIENTS Children from birth to less than or equal to 21 years old. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 7,313 pediatric procedural sedations were performed using IV ketamine + propofol as the primary sedative regimen. Median age was 84 months (range, < 1 mo to ≤ 21 yr; interquartile range, 36-144); 80.6% were American Society of Anesthesiologists-Physical Status less than III. The majority of sedation was performed in dedicated sedation or radiology units (76.1%). Procedures were successfully completed in 99.8% of patients. Anticholinergics (glycopyrrolate and atropine) or benzodiazepines (midazolam and lorazepam) were used in 14.2% and 41.3%, respectively. The overall adverse event and serious adverse event rates were 9.79% (95% CI, 9.12-10.49%) and 3.47% (95% CI, 3.07-3.92%), respectively. No deaths occurred. Risk factors associated with an increase in odds of adverse event included ASA status greater than or equal to III, dental suite, cardiac catheterization laboratory or radiology/sedation suite location, a primary diagnosis of having a gastrointestinal illness, and the coadministration of an anticholinergic. CONCLUSIONS Using Pediatric Sedation Research Consortium data, we describe the diverse use of IV ketamine + propofol for procedural sedation in the largest reported cohort of children to date. Data from this study may be used to design sufficiently powered prospective randomized, double-blind studies comparing outcomes of sedation between commonly administered sedative and analgesic medication regimens.

Purpose To evaluate the difference in tubal ligation use between rural and urban counties in the state of Georgia, USA. Methods The study population included 2,160 women aged 22-45. All participants completed a detailed interview on their reproductive histories. County of residence was categorized using the National Center for Health Statistics Urban-Rural Classification Scheme. We estimated the association between urbanization of county of residence and tubal ligation using Cox regression. Among women with a tubal ligation, we examined factors associated with prior contraception use and the desire for more children. Findings After adjustment for covariates, women residing in rural counties had twice the incidence rate of tubal ligation compared with women in large metropolitan counties (adjusted hazard ratio [aHR] = 2.0, 95% CI = 1.4-2.9) and were on average 3 years younger at the time of the procedure. No differences were observed between small metropolitan and large metropolitan counties (aHR = 1.1, CI = 0.9-1.5). Our data suggest that women from large metropolitan counties are slightly more likely than women from rural counties to use hormonal contraception or long-acting reversible contraception prior to tubal ligation and to desire more children after tubal ligation. Conclusions Women from rural counties are more likely to undergo a tubal ligation than their urban counterparts. Our results suggest that circumstances regarding opting for tubal ligation may differ between urban and rural areas, and recommendations of alternative contraceptive options may need to be tailored differently for rural areas.

To evaluate outcomes in patients receiving balanced fluids for resuscitation in pediatric severe sepsis.Observational cohort review of prospectively collected data from a large administrative database.PICUs from 43 children's hospitals.PICU patients diagnosed with severe sepsis.None.We reviewed data from the Pediatric Health Information System database from 2004 to 2012. Children with pediatric severe sepsis receiving balanced fluids for resuscitation in the first 24 and 72 hours of treatment were compared to those receiving unbalanced fluids. Thirty-six thousand nine hundred eight patients met entry criteria for analysis. Two thousand three hundred ninety-eight patients received exclusively balanced fluids at 24 hours and 1,641 at 72 hours. After propensity matching, the 72-hour balanced fluids group had lower mortality (12.5% vs 15.9%; p = 0.007; odds ratio, 0.76; 95% CI, 0.62-0.93), lower prevalence of acute kidney injury (16.0% vs 19.2%; p = 0.028; odds ratio, 0.82; 95% CI, 0.68-0.98), and fewer vasoactive infusion days (3.0 vs 3.3 d; p0.001) when compared with the unbalanced fluids group.In this retrospective analysis carried out by propensity matching, exclusive use of balanced fluids in pediatric severe sepsis patients for the first 72 hours of resuscitation was associated with improved survival, decreased prevalence of acute kidney injury, and shorter duration of vasoactive infusions when compared with exclusive use of unbalanced fluids.

Introduction This study's objective was to evaluate quantitative electromyography (QEMG) using multiple-motor-unit (multi-MUP) analysis in Duchenne muscular dystrophy (DMD). Methods Ambulatory DMD boys, aged 5–15 years, were evaluated with QEMG at 6-month intervals over 14 months. EMG was performed in the right biceps brachii (BB) and tibialis anterior (TA) muscles. Normative QEMG data were obtained from age-matched healthy boys. Wilcoxon signed-rank tests were performed. Results Eighteen DMD subjects were enrolled, with a median age of 7 (interquartile range 7–10) years. Six-month evaluations were performed on 14 subjects. QEMG showed significantly abnormal mean MUP duration in BB and TA muscles, with no significant change over 6 months. Conclusions QEMG is a sensitive electrophysiological marker of myopathy in DMD. Preliminary data do not reflect a significant change in MUP parameters over a 6-month interval; long-term follow-up QEMG studies are needed to understand its role as a biomarker for disease progression.

Purpose: The benefits of minimally invasive surgery in pediatric urology, such as reduced length of hospital stay and postoperative pain, are less predictable compared to findings in the adult literature. We evaluated the choices that adult patients make for themselves and their children regarding scar location.Materials and Methods: We surveyed the preference for scar location/size based on surgery for bladder and kidney procedures with additional questions assessing the impact of a hidden incision, length of hospital stay and pain. The survey was posted to Amazon® Mechanical Turk®.Results: We analyzed a total of 954 completed surveys. Surgical history was reported in 660 surveys (69%) with scar bother reported in 357 (54.2%). For pelvic surgery the initial choice was a Pfannenstiel incision for 434 respondents (45.5%), laparoscopy port incisions for 392 (41.1%) and no preference for incision location for 126 (13.2%). When incisions were illustrated relative to undergarments, 718 respondents (75.3%) chos...

Applied mechanical vibration in pediatric and adult populations has been shown to be an effective analgesic for acute and chronic pain, including needle pain. Studies among the neonatal population are lacking. According to the Gate Control Theory, it is expected that applied mechanical vibration will have a summative effect with standard nonpharmacologic pain control strategies, reducing behavioral and physiologic pain responses to heel lancing.To determine the safety and efficacy of mechanical vibration for relief of heel lance pain among neonates.In this parallel design randomized controlled trial, eligible enrolled term or term-corrected neonates (n = 56) in a level IV neonatal intensive care unit were randomized to receive either sucrose and swaddling or sucrose, swaddling, and vibration for heel lance analgesia. Vibration was applied using a handheld battery-powered vibrator (Norco MiniVibrator, Hz = 92) to the lateral aspect of the lower leg along the sural dermatome throughout the heel lance procedure. Neonatal Pain, Agitation, and Sedation Scale (N-PASS) scores, heart rate, and oxygen saturations were collected at defined intervals surrounding heel lancing.Infants in the vibration group (n = 30) had significantly lower N-PASS scores and more stable heart rates during heel stick (P = .006, P = .037) and 2 minutes after heel lance (P = .002, P = .016) than those in the nonvibration group. There were no adverse behavioral or physiologic responses to applied vibration in the sample.Applied mechanical vibration is a safe and effective method for managing heel lance pain. This pilot study suggests that mechanical vibration warrants further exploration as a nonpharmacologic pain management tool among the neonatal population.

Most studies of ketamine administered to children for procedural sedation are limited to emergency department use. The objective of this study was to describe the practice of ketamine procedural sedation outside of the operating room and identify risk factors for adverse events.Observational cohort review of data prospectively collected from 2007 to 2015 from the multicenter Pediatric Sedation Research Consortium.Sedation services from academic, community, free-standing children's hospitals and pediatric wards within general hospitals.Children from birth to 21 years old or younger.None.Describe patient characteristics, procedure type, and location of administration of ketamine procedural sedation. Analyze sedation-related adverse events and severe adverse events. Identify risk factors for adverse events using multivariable logistic regression. A total of 22,645 sedations performed using ketamine were analyzed. Median age was 60 months (range,1 mo to22 yr); 72.0% were American Society of Anesthesiologists-Physical Status less than III. The majority of sedations were performed in dedicated sedation or radiology units (64.6%). Anticholinergics, benzodiazepines, or propofol were coadministered in 19.8%, 57.9%, and 35.4%, respectively. The overall adverse event occurrence rate was 7.26% (95% CI, 6.92-7.60%), and the frequency of severe adverse events was 1.77% (95% CI, 1.60-1.94%). Procedures were not completed in 39 of 19,747 patients (0.2%). Three patients experienced cardiac arrest without death, all associated with laryngospasm.This is a description of a large prospectively collected dataset of pediatric ketamine administration predominantly outside of the operating room. The overall incidence of severe adverse events was low. Risk factors associated with increased odds of adverse events were as follows: cardiac and gastrointestinal disease, lower respiratory tract infection, and the coadministration of propofol and anticholinergics.

To improve opioid stewardship for umbilical hernia repair in children.An educational intervention was conducted at 9 centers with 79 surgeons. The intervention highlighted the importance of opioid stewardship, demonstrated practice variation, provided prescribing guidelines, encouraged non-opioid analgesics, and encouraged limiting doses/strength if opioids were prescribed. Three to six months of pre-intervention and 3 months of post-intervention prescribing practices for umbilical hernia repair were compared.A total of 343 patients were identified in the pre-intervention cohort and 346 in the post-intervention cohort. The percent of patients receiving opioids at discharge decreased from 75.8% pre-intervention to 44.6% (p 0.001) post-intervention. After adjusting for age, sex, umbilicoplasty, and hospital site, the odds ratio for opioid prescribing in the post- versus the pre-intervention period was 0.27 (95% CI = 0.18-0.39, p 0.001). Among patients receiving opioids, the number of doses prescribed decreased after the intervention (adjusted mean 14.3 to 10.4, p 0.001). However, the morphine equivalents/kg/dose did not significantly decrease (adjusted mean 0.14 to 0.13, p = 0.20). There were no differences in returns to emergency departments or hospital readmissions between the pre- and post-intervention cohorts.Opioid stewardship can be improved after pediatric umbilical hernia repair using a low-fidelity educational intervention.Retrospective cohort study.Level II.

Objectives: Current technology advances in virtual surgery modeling and computational flow dynamics allow preoperative individualized computer-based design of Fontan operation. To determine potential role of those innovations in patients undergoing hepatic vein incorporation (HVI) following Kawashima operation, we retrospectively examined historic cohort of patients who underwent HVI following Kawashima with focus on regression of pulmonary arteriovenous malformations (PAVMs). Methods: Twenty-two children with single ventricle and interrupted inferior vena cava underwent Kawashima operation (2002-12). Twenty-one (96%) patients had left atrial isomerism and 21 (96%) had undergone prior first-stage palliation. Clinical outcomes were examined. Results: Mean O2 saturation (SaO2) increased from 77% ± 8% to 85% ± 6% ( P = .002) after Kawashima. Fifteen (68%) patients developed PAVMs. Eighteen patients underwent HVI (median age and interval from Kawashima: 4.4 and 3.7 years, respectively). Mean SaO2 prior to HVI was 77% ± 8% and increased to 81% ± 10% at the time of hospital discharge ( P = .250), with five patients requiring home oxygen. On follow-up, mean SaO2 increased to 95% ± 4% ( P < .001). Overall ten-year survival following Kawashima was 94%. Conclusions: A large number of patients develop PAVMs and subsequent cyanosis after Kawashima operation. Early following HVI, SaO2 is commonly low and insignificantly different from that prior to HVI. Although SaO2 will improve on follow-up in most patients, a number of patients continue to have low saturations, indicating incomplete resolution of PAVMs. Given the heterogeneity of those patients and lack of preoperative predictors for complete PAVM regression, our findings suggest a role for virtual surgery to determine optimal individual procedure design that would provide even distribution of hepatic blood flow to both pulmonary arteries.

Pediatric guidelines for the management of nonalcoholic fatty liver disease (NAFLD) recommend a healthy diet as treatment. Reduction of sugary foods and beverages is a plausible but unproven treatment.To determine the effects of a diet low in free sugars (those sugars added to foods and beverages and occurring naturally in fruit juices) in adolescent boys with NAFLD.An open-label, 8-week randomized clinical trial of adolescent boys aged 11 to 16 years with histologically diagnosed NAFLD and evidence of active disease (hepatic steatosis10% and alanine aminotransferase level ≥45 U/L) randomized 1:1 to an intervention diet group or usual diet group at 2 US academic clinical research centers from August 2015 to July 2017; final date of follow-up was September 2017.The intervention diet consisted of individualized menu planning and provision of study meals for the entire household to restrict free sugar intake to less than 3% of daily calories for 8 weeks. Twice-weekly telephone calls assessed diet adherence. Usual diet participants consumed their regular diet.The primary outcome was change in hepatic steatosis estimated by magnetic resonance imaging proton density fat fraction measurement between baseline and 8 weeks. The minimal clinically important difference was assumed to be 4%. There were 12 secondary outcomes, including change in alanine aminotransferase level and diet adherence.Forty adolescent boys were randomly assigned to either the intervention diet group or the usual diet group (20 per group; mean [SD] age, 13.0 [1.9] years; most were Hispanic [95%]) and all completed the trial. The mean decrease in hepatic steatosis from baseline to week 8 was significantly greater for the intervention diet group (25% to 17%) vs the usual diet group (21% to 20%) and the adjusted week 8 mean difference was -6.23% (95% CI, -9.45% to -3.02%; P .001). Of the 12 prespecified secondary outcomes, 7 were null and 5 were statistically significant including alanine aminotransferase level and diet adherence. The geometric mean decrease in alanine aminotransferase level from baseline to 8 weeks was significantly greater for the intervention diet group (103 U/L to 61 U/L) vs the usual diet group (82 U/L to 75 U/L) and the adjusted ratio of the geometric means at week 8 was 0.65 U/L (95% CI, 0.53 to 0.81 U/L; P .001). Adherence to the diet was high in the intervention diet group (18 of 20 reported intake of3% of calories from free sugar during the intervention). There were no adverse events related to participation in the study.In this study of adolescent boys with NAFLD, 8 weeks of provision of a diet low in free sugar content compared with usual diet resulted in significant improvement in hepatic steatosis. However, these findings should be considered preliminary and further research is required to assess long-term and clinical outcomes.ClinicalTrials.gov Identifier: NCT02513121.

BACKGROUND AND OBJECTIVES: There is renewed interest in adrenocorticotropic hormone (ACTH) for the treatment of nephrotic syndrome. We evaluated the efficacy and safety of ACTH in children with frequently relapsing or steroid-dependent nephrotic syndrome in a randomized trial. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Participants aged 2–20 years old with frequently relapsing or steroid-dependent nephrotic syndrome were enrolled from 16 sites in the United States and randomized 1:1 to ACTH (repository corticotropin injection) or no relapse-preventing treatment. ACTH treatment regimen was 80 U/1.73 m(2) administered twice weekly for 6 months, followed by 40 U/1.73 m(2) administered twice weekly for 6 months. The primary outcome was disease relapse during the first 6 months. Participants in the control group were offered crossover to ACTH treatment if they relapsed within 6 months. Secondary outcomes were relapse after ACTH dose reduction and treatment side effects. RESULTS: The trial was stopped at a preplanned interim analysis after enrollment of 31 participants because of a lack of discernible treatment efficacy. Fourteen out of 15 (93%) participants in the ACTH arm experienced disease relapse in the first 6 months, with a median time to first relapse of 23 days (interquartile range, 9–32), compared with 15 out of 16 (94%) participants and at a median of 21 days (interquartile range, 14–51) in the control group. There was no difference in the proportion of relapsed patients (odds ratio, 0.93; 95% confidence interval, 0.05 to 16.40; P>0.99) or time to first relapse (hazard ratio, 1.03; 95% confidence interval, 0.50 to 2.15; P=0.93). Thirteen out of 16 participants in the control group crossed over to ACTH treatment. Three out of 28 participants completed 12 months of ACTH treatment; the others exited the trial because of frequent relapses or side effects. There were no disease relapses after ACTH dose reduction among the three participants. Most side effects were mild and similar to side effects of corticosteroids. CONCLUSIONS: ACTH at 80 U/1.73 m(2) administered twice weekly was ineffective at preventing disease relapses in pediatric nephrotic syndrome.

Summary Background/Aims Guidelines for referral of children to general anesthesia (GA) to complete MRI studies are lacking. We devised a pediatric procedural sedation guide to determine whether a pediatric procedural sedation guide would decrease serious adverse events and decrease failed sedations requiring rescheduling with GA. Methods We constructed a consensus-based sedation guide by combining a retrospective review of reasons for referral of children to GA (n = 221) with published risk factors associated with the inability to complete the MRI study with sedation. An interrupted time series analysis of 11 530 local sedation records from the Pediatric Sedation Research Consortium between July 2008 and March 2013, adjusted for case-mix differences in the pre- and postsedation guide cohorts, evaluated whether a sedation guide resulted in decreased severe adverse events (SAE) and failed sedation rates. Results A significant increase in referrals to GA following implementation of a sedation guide occurred (P < 0.001), and fewer children with an ASA-PS class ≥III were sedated using procedural sedation (P < 0.001). There was no decrease in SAE (P = 0.874) or in SAE plus airway obstruction with concurrent hypoxia (P = 0.435). There was no change in the percentage of failed sedations (P = 0.169). Conclusions More studies are needed to determine the impact of a sedation guide on pediatric procedural sedation services.

The purpose of this study was to implement a novel surgeon-reported categorization (SRC) for pediatric appendicitis severity and determine if SRC was associated with outcomes. We conducted a retrospective review of appendectomies by 15 surgeons within a single center from January to December 2016. The SRC was defined as: simple (category 1), gangrenous or adherent (category 2A), perforation with localized abscess (category 2B), and perforation with gross contamination (category 2C). Logistic regression modeled the surgical site infections (SSI) and returns to the system. Cox proportional hazards analyses modeled the length of stay (LOS). The cohort included 697 patients (mean age 10.7 years). Compliance with SRC documentation increased from 33.5 to 85.9%. Review of operative findings revealed 100% concordance with SRC. The combined morbidity (SSI and revisits) rate was 9.8%. Category 2C patients had the highest odds of SSI (odds ratio 3.37 95% confidence interval 1.07–10.59). Median LOS increased with each category (category 1 = 1d, category 2A = 2d, category 2B = 4d, category 2C = 6d). When modeling intra-abdominal abscess, SRC displayed an improved model calibration and discrimination compared to wound class. SRC implementation is feasible and provides a granular assessment of appendicitis severity and outcomes. SRC may guide future quality improvement through development of grade-specific care pathways.

Clinical practice guidelines (CPG) have been shown to decrease practice variation, reduce resource use, and improve patient outcomes. The purpose of this study was to audit compliance of a pediatric complicated appendicitis CPG to identify areas for continued improvement. A comprehensive complicated appendicitis CPG was implemented in a children’s hospital system. Outcomes were compared for 48 months pre- (01/2012 to 12/2015) and 28 months post-implementation (01/2016 to 04/2018). A detailed compliance audit was nested within the post-implementation period in 60 consecutive patients from 11/2017 to 03/2018. Feedback was provided to care providers throughout the audit. Overall, 2370 children with complicated appendicitis were identified (1366 pre-CPG and 1004 post-CPG). The CPG resulted in decrease in mean length of stay from 5.3 days to 4.5 days (p = 0.751), postoperative returns to the system (13.0% to 10.1%, p = 0.030), and readmissions (5.3% to 4.3%, p = 0.237). Central line use decreased from 11.2% to 5.5% (p

Objective Children with juvenile idiopathic arthritis (JIA) are at risk for temporomandibular joint (TMJ) arthritis. This can lead to pain, limited mouth opening, facial asymmetry, and malocclusion. Our objective was to characterize patients with JIA and TMJ involvement in a single center. Study Design This was a retrospective study of children with JIA evaluated at Children's Healthcare of Atlanta. Inclusion criteria were confirmed JIA and jaw complaints. Medical records were reviewed to document demographics, JIA information, age at first TMJ complaint, and involvement of other joints. Descriptive statistics were computed. Results Majority of patients were white (mean age 13 years; range 5-18 years) with polyarticular rheumatoid factor (RF) negative or oligoarticular persistent JIA. Some were antinuclear antibody (ANA) positive, RF positive, or human leukocyte antigen (HLA)-B27 positive. Patients had involvement of other joints (e.g., fingers, knees, wrists). Of those with TMJ symptoms, 6 (10%) had TMJ arthritis. Conclusions In our cohort, 60 (10%) of patients were diagnosed with TMJ arthritis. In this population, patients who are female, white, RF negative, HLA-B27 negative, ANA negative, and polyarticular RF-negative subtype and have involvement of other joints have a higher likelihood of having TMJ symptoms. If a patient meets these criteria, careful evaluation of TMJs should take place.

AIMS: Methotrexate (MTX) is standard treatment in pediatric chronic anterior uveitis (CAU). Addition of tumor necrosis factor-α inhibitors (TNFi) is often needed. We describe the timing and risk factors for TNFi use in children with CAU on MTX. METHODS: In this retrospective study, we reviewed 51 records, and 46 met inclusion criteria. Primary outcome was the addition of TNFi due to active CAU per Standardization of Uveitis Nomenclature criteria. Time to TNFi and factors associated with their addition were assessed using survival analysis models. RESULTS: Of 46 children treated with MTX for uveitis (36 juvenile idiopathic arthritis-associated uveitis, 10 idiopathic CAU), 72% had ocular complications. MTX was started a median of 5.0 months, and TNFi 43 months from uveitis diagnosis. Kaplan–Meier estimates suggest that cumulatively, 12% (95% CI: 4–23%) start TNFi within 6 months of MTX, 21% (12–37%) within 1 year, and 39% (24–54%) within 2 years. On Cox Proportional Hazard regression analysis, children with idiopathic CAU required TNFi earlier in their uveitis course (at 3 months (Hazard Ratio 6.06; 95% confidence interval (1.25–29.41))). Females appeared less likely to require TNFi early. Children treated in 2012 and later were more likely to receive TNFi earlier than those treated before 2012. CONCLUSION: Little is known about optimal time to initiate treatment or factors associated with the need to add TNFi in children on MTX. Children with idiopathic CAU and males required TNFi earlier in their course. Factors associated with these potential risk factors for TNFi warrant further investigation.

The appearance of the diaphragmatic curvature and the rib insertion level of the diaphragm on postoperative chest X-ray (CXR) may predict recurrence. Our purpose was to examine the relationship between the curvature of the diaphragm on postoperative CXR and recurrence.We performed a retrospective review of left-sided, Bochdalek congenital diaphragmatic hernia (CDH) surgical repairs from 2004 to 2015 at a single institution. We developed a tool to measure the flatness of the diaphragm on postoperative CXR, termed the diaphragmatic curvature index (τ). The primary outcome of interest was recurrence after surgical repair.Of the 127 patients identified, 54% (n = 69) had a primary repair, while 46% (n = 58) required a patch repair. The overall recurrence rate was 21.3% (n = 27). There was no difference in median lateral rib insertion level in patients with and without recurrence or those who had a primary or patch repair. The overall median diaphragmatic curvature index was 6.29 (interquartile range [IQR] 5.30-8.09) and was not significantly different among patients who had a recurrence (6.00, IQR 5.34-8.24) and those who did not (6.46, IQR 5.24-8.07) (P = .853). Within the primary repair group (6.34 versus 6.93, P = .84) and the patch repair group (5.59 versus 6.18, P = .46), the median diaphragmatic curvature index was not different among patients who had a recurrence and those who did not.A flat appearance of the diaphragm on postoperative CXR as measured by the median diaphragmatic curvature index (τ) is not associated with recurrence. The shape of the diaphragm on CXR after CDH repair may not be predictive of recurrence as previously thought.

Background: Necrotizing enterocolitis (NEC) is a leading contributor of neonatal morbidity and mortality. Few risk-prediction models exist to inform discussions with families before surgery or guide risk-adjustment for between center comparisons of surgical outcomes. Useful prediction models should be parsimonious, validated, well-calibrated, and include inputs using readily accessible pre-operative data. In addition, the performance of currently available prediction tools, including the Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE-II), Vermont Oxford Risk Adjustment Tool (VON) and American College …

Background The American College of Surgeons in 2015 instituted the Children's Surgery Verification program delineating requirements for hospitals providing pediatric surgical care. Our purpose was to examine possible effects of the Children's Surgery Verification program by evaluating neonates undergoing high-risk operations. Study Design Using the Kid's Inpatient Database 2009, we identified infants undergoing operations for 5 high-risk neonatal conditions. We considered all children's hospitals and children's units Level I centers and considered all others Level II/III. We estimated the number of neonates requiring relocation and the additional distance traveled. We used propensity score adjusted logistic regression to model mortality at Level I vs Level II/III hospitals. Results Overall, 7,938 neonates were identified across 21 states at 91 Level I and 459 Level II/III hospitals. Based on our classifications, 2,744 (34.6%) patients would need to relocate to Level I centers. The median additional distance traveled was 6.6 miles. The maximum distance traveled varied by state, from 200 miles (Montana, Oregon, Colorado, and California). The adjusted odds of mortality at Level II/III vs Level I centers was 1.67 (95% CI 1.44 to 1.93). We estimate 1 life would be saved for every 32 neonates moved. Conclusions Although this conservative estimate demonstrates that more than one-third of complex surgical neonates in 2009 would have needed to relocate under the Children's Surgery Verification program, the additional distance traveled is relatively short for most but not all, and this program might improve mortality. Local level ramifications of this novel national program require additional investigation.

Background Approximately 8–23% of premature infants develop pulmonary hypertension (PH), and this diagnosis confers a higher possibility of mortality. As a result, professional societies recommend PH screening in premature infants. However, the risk factors for and the outcomes of PH may differ depending on the timing of its diagnosis, and little evidence is available to determine at-risk infants in the referral neonatal population. The objective of this study was to define clinical and echocardiographic characteristics of infants with pulmonary hypertension during the neonatal hospital course and at or near-term . Methods Infants who had the following billing codes: < 32 weeks, birth weight

Purpose Though growth in children's surgical expenditures has been documented, procedure-specific differences in volume and costs at children's hospitals (CH) and non-hildren's hospitals (NCH) have not been explored. Our purpose was to compare trends in volume and costs of common pediatric surgical procedures between CH and NCH. Methods We performed a review of the 2000–2009 Kids' Inpatient Database identifying all cases of appendectomy for uncomplicated appendicitis (AP), tonsillectomy and adenoidectomy (TA), fundoplication (FP), humeral fracture repair (HFR), pyloromyotomy (PYL), and cholecystectomy (CHOLE). Trends in case volume and costs were examined at CH versus NCH. Results The proportion of surgical care at CH increased for all procedures from 2000 to 2009. TA and CHOLE demonstrated higher costs per case at CH. Positive growth over time in cost per case at CH was seen for AP and FP, with the cost per case of FP increasing by 21% between 2006 and 2009. Conclusions The proportion of surgeries performed at CH is continuing to grow alongside proportionate increases in costs, however costs for certain procedures are higher at CH than NCH. Further investigation is needed to explore cost containment at CH while still maintaining specialized, high quality surgical care. Level of evidence Level III.

Objectives Acute intoxications in children account for 4.6% of annual admissions to the PICU. We aimed to describe the interventions and monitoring required for children admitted to the PICU following intoxications with the ultimate goal of determining patient and intoxication characteristics associated with the need for PICU interventions. Design Retrospective review of prospectively collected data from Virtual Pediatric Systems, LLC. Setting United States PICUs participating in the Virtual Pediatric Systems database from 2011 to 2014. Patients Less than or equal to 18 years old admitted to a PICU with a diagnostic code for poisoning, ingestion, intoxication, or overdose. Interventions None. Measurements and main results In total, 12,021 patients were included with a median PICU length of stay of 0.97 days (interquartile range, 0.67-1.60). Seventy-eight percent of the intoxications were intentional. The top five classes of medications ingested were unknown substances (21.6%), antidepressants (11.5%), other chemicals (10.7%), analgesics (7.3%), and antihypertensives (6.2%). Seventy-six (0.61%) patients died. Any of the interventions reported in the Virtual Pediatric Systems database were performed in only 29.1% of the total cases. Conclusions The majority of cases (70.9%) admitted to the PICU following an intoxication did not undergo any significant intervention. Future studies should focus on distinguishing patient and intoxication characteristics associated with need for PICU intervention to optimize patient safety and minimize resource burden.

BACKGROUND: Upper respiratory infections (URIs) are associated with airway adverse events (AAEs) during general anesthesia. There have been no large studies examining the relationship between URIs and AAEs during pediatric procedural sedation. We hypothesized that there would be a relationship between URI status and AAEs in pediatric procedural sedation. METHODS: We examined prospectively collected data from the Pediatric Sedation Research Consortium database. Specific questions regarding URI status were added to the database to facilitate our analysis. Characteristics of patients, procedure types, adjunctive medications, adverse events, and airway interventions (AIs) were reported. We performed bivariate analysis of adverse events and URI status, then used a multivariable logistic regression model to assess the relationship between URI status and adverse events. We examined the secondary outcome of AI similarly. RESULTS: Of the 105 728 sedations entered into the Pediatric Sedation Research Consortium database during the study period, we were able to use 83 491 for analysis. Controlling for multiple patient, drug, and procedure characteristics, recent and current URI were associated with increased frequency of AAEs. In general, the frequency of AAEs and AIs increased from recent URI, to current URI-clear secretions to current URI-thick secretions. We did not find a relationship between URI status and non-AAEs. CONCLUSIONS: URI status is associated with a statistically significant increase in frequency of AAEs and AI during pediatric procedural sedation for the population sedated by our consortium. Although URI status merits consideration in determining potential risk for sedation, rates of some AAEs and AIs remained low regardless of URI status.

We conducted a retrospective review of electronic medical records of all cases of bacterial meningitis in neonates and young infants at our institution from 2004 to 2014. Fifty-six cases were identified. The most common causative organism was group B streptococcus, followed by Escherichia coli and then Listeria monocytogenes. Fortyfour of the 56 patients in the study had abnormalities of the blood white blood cell (WBC) count. The most common WBC count abnormalities were leukopenia and elevation of the immature to total (I:T) neutrophil ratio. Six patients in the case series lacked cerebrospinal fluid (CSF) pleocytosis. Overall, just 3 of the 56 patients had normal WBC count with differential, CSF WBC count, and urinalysis. Only 1 of the 56 patients was well appearing with all normal lab studies. Our study indicates that bacterial meningitis may occur without CSF pleocytosis but very infrequently occurs with all normal lab studies and well appearance.

Purpose: Myocardial dysfunction is a known complication in patients with pediatric septic shock (PSS); however, its clinical significance remains unclear. The purpose of this study was to characterize left ventricular (LV) and right ventricular (RV) dysfunction and their prevalence in patients with PSS using echocardiography (echo) and to investigate their associations with the severity of illness and clinical outcomes. Methods: Retrospective chart review between 2010 and 2015 from 2 tertiary care pediatric intensive care units. Study included 78 patients (mean age 9.3 ± 7 years) from birth up to 21 years who fulfilled criteria for fluid- and catecholamine-refractory septic shock. Echocardiographic parameters of systolic, diastolic, and global function were measured offline. They were correlated with admission Pediatric Risk of Mortality III (PRISM III) and Pediatric Logistic Organ Dysfunction scores, vasoactive–inotrope score (VIS), β-type natriuretic peptide (BNP), lactate, type of shock, duration of mechanical ventilation (MV), intensive care unit and hospital length of stay, and mortality. Results: Overall, 28-day mortality was 26%, and 88% patients required MV. Prevalence of LV dysfunction was 72% and RV dysfunction was 63%. LV systolic dysfunction (fractional shortening z score Conclusion: Myocardial dysfunction is highly prevalent in PSS but is not associated with mortality. LV systolic dysfunction is associated with a higher severity of illness, use of vasoactives, and BNP, whereas RV systolic dysfunction is associated with cold shock. Further studies are needed to determine the utility of echo in the bedside management of patients with PSS.

Background Right ventricular systolic dysfunction (RVSD) is a predictor of outcomes in dilated cardiomyopathy (DCM) in adults, but little is known in children. Tricuspid annular plane systolic excursion (TAPSE) has emerged as a reliable tool to assess RVSD. We sought to determine the prevalence and prognostic significance of RVSD using TAPSE in children with DCM. Methods The first echocardiogram at the time of diagnosis with DCM was analyzed to obtain left ventricular ejection fraction (LVEF) and 2D TAPSE. RVSD was defined as TAPSE age-based z-score ≤−2. The association of a composite primary endpoint including death, mechanical support, or transplantation with RVSD was analyzed using LVEF and TAPSE. Results Of the 96 patients, RVSD was noted in 84 (88%). During a median follow-up of 17.5 months (IQR 1.4, 76.2), the primary endpoints were reached in 59%. There was a lower LVEF in patients with RVSD (P=.016). Moderate or severe RVSD showed a significant association with the composite primary endpoint (unadjusted OR 2.7 [95% CI: 1.15–6.33], P=.023). Kaplan-Meier analysis showed that the event-free survival was significantly lower in patients with LVEF ≤30% and TAPSE z-score ≤−4. Conclusion Children with DCM have a high prevalence of RVSD based on reduced TAPSE, and those with moderate or severe RVSD have worse clinical outcomes.

Infants with congenital cardiac disease (CCD) often require gastrostomy tube placement (GT) and need antireflux procedures, such as fundoplications. Our purpose was to compare morbidity/mortality rates among infants with CCD undergoing GT, fundoplication, or both. Using the NSQIP-Pediatric, we identified 4070 patients

Background There is significant variation surrounding the indications, surgical approaches, and outcomes for children undergoing antireflux procedures (ARPs) resulting in geographic variation of care. Our purpose was to quantify this geographic variation in the utilization of ARPs in children. Methods A cross-sectional analysis of the 2009 Kid's Inpatient Database was performed to identify patients with gastroesophageal reflux disease or associated diagnoses. Regional surgical utilization rates were determined, and a mixed effects model was used to identify factors associated with the use of ARPs. Results Of the 148,959 patients with a diagnosis of interest, 4848 (3.3%) underwent an ARP with 2376 (49%) undergoing a laparoscopic procedure. The Northeast (2.0%) and Midwest (2.2%) had the lowest overall utilization of surgery, compared with the South (3.3%) and West (3.4%). After adjustment for age, case-mix, and surgical approach, variation persisted with the West and the South demonstrating almost two times the odds of undergoing an ARP compared with the Northeast. Surgical utilization rates are independent of state-level volume with some of the highest case volume states having surgical utilization rates below the national rate. In the West, the use of laparoscopy correlated with overall utilization of surgery, whereas surgical approach was not correlated with ARP use in the South. Conclusions Significant regional variation in ARP utilization exists that cannot be explained entirely by differences in patient age, race/ethnicity, case-mix, and surgical approach. In order to decrease variation in care, further research is warranted to establish consensus guidelines regarding indications for the use ARPs for children.
