Objective To determine if low household income is associated with disease severity following emergency department (ED) discharge in children with acute gastroenteritis (AGE). Methods We conducted a secondary analysis employing data collected in 10 US-based tertiary-care, pediatric EDs between 2014 and 2017. Participants were aged 3 to 48 months and presented for care due to AGE. Income status was defined based on 1) home ZIP Code median annual home income and 2) percentage of home ZIP Code households below the poverty threshold. The primary outcome was moderate-to-severe AGE, defined by a post-ED visit Modified Vesikari Scale (MVS) score ≥9. Secondary outcomes included in-person revisits, revisits with intravenous rehydration, hospitalization, and etiologic pathogens. Results About 943 (97%) participants with a median age of 17 months (interquartile range 10, 28) completed follow-up. Post-ED visit MVS scores were lower for the lowest household income group (adjusted: -0.60; 95% confidence interval [CI]: -1.13, -0.07). Odds of experiencing an MVS score ≥9 did not differ between groups (adjusted odds ratio: 0.91; 95% CI: 0.54, 1.52). No difference in the post-ED visit MVS score or the proportion of participants with scores ≥9 was observed using the national poverty threshold definition. For both income definitions, there were no differences in terms of revisits following discharge, hospitalizations, and intravenous rehydration. Bacterial enteropathogens were more commonly identified in the lowest socioeconomic group using both definitions. Conclusions Lower household income was not associated with increased disease severity or resource use. Economic disparities do not appear to result in differences in the disease course of children with AGE seeking ED care.

OBJECTIVES: Although most acute gastroenteritis (AGE) episodes in children rapidly self-resolve, some children go on to experience more significant and prolonged illness. We sought to develop a prognostic score to identify children at risk of experiencing moderate-to-severe disease after an index emergency department (ED) visit. METHODS: Data were collected from a cohort of children 3 to 48 months of age diagnosed with AGE in 16 North American pediatric EDs. Moderate-to-severe AGE was defined as a Modified Vesikari Scale (MVS) score ≥9 during the 14-day post-ED visit. A clinical prognostic model was derived using multivariable logistic regression and converted into a simple risk score. The model’s accuracy was assessed for moderate-to-severe AGE and several secondary outcomes. RESULTS: After their index ED visit, 19% (336/1770) of participants developed moderate-to-severe AGE. Patient age, number of vomiting episodes, dehydration status, prior ED visits, and intravenous rehydration were associated with MVS ≥9 in multivariable regression. Calibration of the prognostic model was strong with a P value of 0.77 by the Hosmer-Lemenshow goodness-of-fit test, and discrimination was moderate with an area under the receiver operator characteristic curve of 0.68 (95% confidence interval [CI] 0.65–0.72). Similarly, the model was shown to have good calibration when fit to the secondary outcomes of subsequent ED revisit, intravenous rehydration, or hospitalization within 72 hours after the index visit. CONCLUSIONS: After external validation, this new risk score may provide clinicians with accurate prognostic insight into the likely disease course of children with AGE, informing disposition decisions, anticipatory guidance, and follow-up care.

Background Gastroenteritis is a common and impactful disease in childhood. Probiotics are often used to treat acute gastroenteritis (AGE); however, in a large multicenter randomized controlled trial (RCT) in 971 children, Lactobacillus rhamnosus GG (LGG) was no better than placebo in improving patient outcomes. Objectives We sought to determine whether the effect of LGG is associated with age, weight z score and weight percentile adjusted for age and sex, or dose per kilogram administered. Methods This was a preplanned secondary analysis of a multicenter double-blind RCT of LGG 1 × 1010 CFU twice daily for 5 d or placebo in children 3-48 mo of age with AGE. Our primary outcome was moderate to severe gastroenteritis. Secondary outcomes included diarrhea and vomiting frequency and duration, chronic diarrhea, and side effects. We used multivariable linear and nonlinear models testing for interaction effects to assess outcomes by age, weight z score and weight percentile adjusted for age and sex, and dose per kilogram of LGG received. Results A total of 813 children (84%) were included in the analysis; 413 received placebo and 400 LGG. Baseline characteristics were similar between treatment groups. There were no differential interaction effects across ranges of age (P-interaction = 0.32), adjusted weight z score (P-interaction = 0.43), adjusted weight percentile (P-interaction = 0.45), or dose per kilogram of LGG received (P-interaction = 0.28) for the primary outcome. Whereas we found a statistical association favoring placebo at the extremes of adjusted weight z scores for the number of vomiting episodes (P-interaction = 0.02) and vomiting duration (P-interaction = 0.0475), there were no statistically significant differences in other secondary outcome measures (all P-interactions > 0.05). Conclusions LGG does not improve outcomes in children with AGE regardless of the age, adjusted weight z score, and adjusted weight percentile of participants, or the probiotic dose per kilogram received. These results further strengthen the conclusions of low risk of bias clinical trials which demonstrate that LGG provides no clinical benefit in children with AGE.This trial was registered at clinicaltrials.gov as NCT01773967.

Recent studies highlight the importance of physician readiness to practice beyond graduate training. The Accreditation Council for Graduate Medical Education mandates that pediatric emergency medicine (PEM) fellows be prepared for independent practice by allowing "progressive responsibility for patient care." Prior unpublished surveys of program directors (PDs) indicate variability in approaches to provide opportunities for more independent practice during fellowship training.The aims of the study were to describe practices within PEM fellowship programs allowing fellows to work without direct supervision and to identify any barriers to independent practice in training.An anonymous electronic survey of PEM fellowship PDs was performed. Survey items were developed using an iterative modified Delphi process and pilot tested. Close-ended survey responses and demographic variables were summarized with descriptive statistics. Responses to open-ended survey items were reviewed and categorized by theme.Seventy two of 84 PDs (88%) responded to the survey; however, not all surveys were completed. Of the 68 responses to whether fellows could work without direct supervision (as defined by the Accreditation Council for Graduate Medical Education) during some part of their training, 31 (45.6%) reported that fellows did have this opportunity. In most programs, clinical independence was conditional on specific measures including the number of clinical hours completed, milestone achievement, and approval by the clinical competency committee. Reported barriers to fellow practice without direct oversight included both regulatory and economic constraints.Current training practices that provide PEM fellows with conditional clinical independence are variable. Future work should aim to determine best practices of entrustment, identify ideal transition points, and mitigate barriers to graduated responsibility.

The global pandemic novel coronavirus 2019 has upended healthcare and medical education, particularly in disease epicenters such as New York City. In this piece, we seek to describe the collective experiences and lessons learned by the New York City pediatric emergency medicine fellowship directors in clinical, educational, investigative, and psychological domains, in hopes of engendering conversation and informing future disaster response efforts.

Nonadherence in clinical trials affects safety and efficacy determinations. Predictors of nonadherence in pediatric acute illness trials are unknown. We sought to examine predictors of nonadherence in a multicenter randomized trial of 971 children with acute gastroenteritis receiving a 5-day oral course of Lactobacillus rhamnosus GG or placebo. Adherence, defined as consuming all doses of the product, was reported by the parents and recorded during daily follow-up contacts. Of 943 patients with follow-up data, 766 (81.2%) were adherent. On multivariate analysis, older age (OR 1.19; 95% CI: 1.00-1.43), increased vomiting duration (OR 1.23; 95% CI: 1.05-1.45), higher dehydration score (OR 1.23, 95% CI: 1.07-1.42), and hospitalization following ED discharge (OR 4.16, 95% CI: 1.21--14.30) were factors associated with nonadherence; however, those with highest severity scores were more likely to adhere (OR 0.87, 95% CI: 0.80-0.95). These data may inform strategies and specific targets to maximize adherence in future pediatric trials.

ObjectiveWe developed a discrete event simulation model to evaluate the impact on system flow of a quality improvement (QI) initiative that included a time-specific protocol to decrease the time to antibiotic delivery for children with cancer and central venous catheters who present to a paediatric ED with fever.MethodsThe model was based on prospective observations and retrospective review of ED processes during the maintenance phase of the QI initiative between January 2016 and June 2017 in a large, urban, academic children’s hospital in New York City, USA. We compared waiting time for full evaluation (WT) and length of stay (LOS) between a model with and a model without the protocol. We then gradually increased the proportion of patients receiving the protocol in the model and recorded changes in WT and LOS.ResultsWe validated model outputs against administrative data from 2016, with no statistically significant differences in average WT or LOS for any emergency severity index (ESI). There were no statistically significant differences in these flow metrics between the model with and the model without the protocol. By increasing the proportion of total patients receiving this protocol, from 0.2% to 1.3%, the WT increased by 2.8 min (95% CI: 0.6 to 5.0) and 7.6 min (95% CI: 2.0 to 13.2) for ESI 2 and ESI 3 patients, respectively. This represents a 14.0% increase in WT for ESI 3 patients.ConclusionsSimulation modelling facilitated the testing of system effects for a time-specific protocol implemented in a large, urban, academic paediatric ED, showing no significant impact on patient flow. The model suggests system resilience, demonstrating no detrimental effect on WT until there is a 7-fold increase in the proportion of patients receiving the protocol.

Study objective This study aimed to explore oral ondansetron usage and impact on outcomes in clinical practice. Methods This observational study was a planned secondary analysis of 2 trials conducted in 10 US and 6 Canadian institutions between 2014 and 2017. Children 3 to 48 months old with gastroenteritis and ≥3 episodes of vomiting in the 24 hours preceding emergency department (ED) presentation were included. Oral ondansetron was administered at the discretion of the provider. The principal outcomes were intravenous fluid administration and hospitalization at the index visit and during the subsequent 72 hours and diarrhea and vomiting frequency during the 24 hours following the ED visit. Results In total, 794 children were included. The median age was 16.0 months (interquartile range 10.0 to 26.0), and 50.1% (398/794) received oral ondansetron. In propensity-adjusted analysis (n=528), children administered oral ondansetron were less likely to receive intravenous fluids at the index visit (adjusted odds ratio [aOR] 0.50; 95% confidence interval [CI] 0.29 to 0.88). There were no differences in the frequencies of intravenous fluid administration within the first 72 hours (aOR 0.65; 95% CI 0.39 to 1.10) or hospitalization at the index visit (aOR 0.31; 95% CI 0.09 to 1.10) or the subsequent 72 hours (aOR 0.52; 95% CI 0.21 to 1.28). Episodes of vomiting (aRR 0.86; 95% CI 0.63 to 1.19) and diarrhea (aRR 1.11; 95% CI 0.93 to 1.32) during the 24 hours following ED discharge also did not differ. Conclusion Among preschool-aged children with gastroenteritis seeking ED care, oral ondansetron administration was associated with a reduction in index ED visit intravenous fluid administration; it was not associated with intravenous fluids administered within 72 hours, hospitalization, or vomiting and diarrhea in the 24 hours following discharge.

Background Intravenous ketorolac is commonly used for treating migraine headaches in children. However, the prerequisite placement of an intravenous line can be technically challenging, time-consuming, and associated with pain and distress. Intranasal ketorolac may be an effective alternative that is needle-free and easier to administer. We aimed to determine whether intranasal ketorolac is non-inferior to intravenous ketorolac for reducing pain in children with migraine headaches. Methods We conducted a randomized double-blind non-inferiority clinical trial. Children aged 8-17 years with migraine headaches, moderate to severe pain, and requiring parenteral analgesics received intranasal ketorolac (1 mg/kg) or intravenous ketorolac (0.5 mg/kg). Primary outcome was reduction in pain at 60 minutes after administration measured using the Faces Pain Scale-Revised (scored 0-10). Non-inferiority margin was 2/10. Secondary outcomes included time to onset of clinically meaningful decrease in pain; ancillary emergency department outcomes (e.g. receipt of rescue medications, headache relief, headache freedom, percentage improvement); 24-hour follow-up outcomes; functional disability; and adverse events. Results Fifty-nine children were enrolled. We analyzed 27 children who received intranasal ketorolac and 29 who received intravenous ketorolac. The difference in mean pain reduction at 60 minutes between groups was 0.2 (95% CI -0.9, 1.3), with the upper limit of the 95% CI being less than the non-inferiority margin. There were no statistical differences between groups for secondary outcomes. Conclusions Intranasal ketorolac was non-inferior to intravenous ketorolac for reducing migraine headache pain in the emergency department.

BACKGROUND: The ACGME Milestone Project created a competency‐based trainee assessment tool. Subcompetencies (SCs) are scored on a 5‐point scale; level 4 is recommended for graduation. The 2018 Milestones Report found that across subspecialties, not all graduates attain level 4 for every SC. OBJECTIVE: The objective was to describe the number of pediatric emergency medicine (PEM) fellows who achieve ≥ level 4 in all 23 SCs at graduation and identify SCs where level 4 is not achieved and factors predictive of not achieving a level 4. METHODS: This is a multicenter, retrospective cohort study of PEM fellows from 2014 to 2018. Program directors provided milestone reports. Descriptive analysis of SC scores was performed. Subanalyses assessed differences in residency graduation scores, first‐year fellowship scores, and the rate of milestone attainment between fellows who did and did not attain ≥ level 4 at graduation. RESULTS: Data from 392 fellows were obtained. There were no SCs in which all fellows attained ≥ level 4 at graduation; the range of fellows scoring

BACKGROUND: Between-country variation in health care resource use and its impact on outcomes in acute care settings have been challenging to disentangle from illness severity by using administrative data. METHODS: We conducted a preplanned analysis employing patient-level emergency department (ED) data from children enrolled in 2 previously conducted clinical trials. Participants aged 3 to RESULTS: In adjusted analysis, unscheduled revisits within 7 days did not differ (adjusted odds ratio [aOR]: 0.72; 95% confidence interval (CI): 0.50 to 1.02). At the index ED visit, although participants in Canada were assessed as being more dehydrated, intravenous fluids were administered more frequently in the United States (aOR: 4.6; 95% CI: 2.9 to 7.1). Intravenous fluid administration rates did not differ after enrollment (aOR: 1.4; 95% CI: 0.7 to 2.8; US cohort with Canadian as referent). Overall, intravenous rehydration was higher in the United States (aOR: 3.8; 95% CI: 2.5 to 5.7). Although hospitalization rates during the 7 days after enrollment (aOR: 1.1; 95% CI: 0.4 to 2.6) did not differ, hospitalization at the index visit was more common in the United States (3.9% vs 2.3%; aOR: 3.2; 95% CI: 1.6 to 6.8). CONCLUSIONS: Among children with gastroenteritis and similar disease severity, revisit rates were similar in our 2 study cohorts, despite lower rates of intravenous rehydration and hospitalization in Canadian-based EDs.

Background Pediatric emergency medicine (PEM) fellowships accept trainees who have completed a residency in either emergency medicine (EM) or pediatrics and have adopted 17 subcompetencies with accompanying set of milestones from these two residency programs. This study aims to examine the changes in milestone scores among common subcompetencies from the end of EM or pediatrics residency to early PEM fellowship and evaluates time to reattainment of scores for subcompetencies in which a decline was noted. Methods This is a national, retrospective cohort study of trainees enrolled in PEM fellowship programs from July 2014 to June 2018. PEM fellowship program directors voluntarily submitted deidentified milestone reports within the study time frame, including end-of-residency reports. Descriptive analyses of milestone scores between end of residency and PEM fellowship were performed. Results Forty-eight U.S. PEM fellowship programs (65%) provided fellowship milestone data on 638 fellows, 218 (34%) of whom also had end-of-residency milestone scores submitted. Of 218 fellows eligible for analysis, 210 (96%) had completed a pediatrics residency and eight (4%) had completed an EM residency. Pediatric-trained fellows had statistically significant decreases in mean milestone scores in all 10 shared subcompetencies. Reattainment of milestone scores across all common subcompetencies for both EM and pediatric-trained PEM fellows occurred by the end of fellowship. Conclusions This study demonstrated declines in milestone scores from the end of primary residency training in pediatrics to early PEM fellowship in shared subcompetencies, which may suggest that performance expectations are reset at the beginning of PEM fellowship. Changes in subcompetency milestone anchors to provide subspecialty-specific context may be needed to more accurately define skills acquisition in the residency-to-fellowship transition.

Importance Despite guidelines endorsing oral rehydration therapy, intravenous fluids are commonly administered to children with acute gastroenteritis in high-income countries. Objective To identify factors associated with intravenous fluid administration and hospitalization in children with acute gastroenteritis. Design, setting, and participants This study is a planned secondary analysis of the Pediatric Emergency Research Canada (PERC) and Pediatric Emergency Care Applied Research Network (PECARN) probiotic trials. Participants include children aged 3 to 48 months with 3 or more watery stools in 24 hours between November 5, 2013, and April 7, 2017, for the PERC study and July 8, 2014, and June 23, 2017, for the PECARN Study. Children were from 16 pediatric emergency departments throughout Canada (6) and the US (10). Data were analyzed from November 2, 2018, to March 16, 2021. Exposures Sex, age, preceding health care visit, distance between home and hospital, country (US vs Canada), frequency and duration of vomiting and diarrhea, presence of fever, Clinical Dehydration Scale score, oral ondansetron followed by oral rehydration therapy, and infectious agent. Main outcomes and measures Intravenous fluid administration and hospitalization. Results This secondary analysis of 2 randomized clinical trials included 1846 children (mean [SD] age, 19.1 [11.4] months; 1007 boys [54.6%]), of whom 534 of 1846 (28.9%) received oral ondansetron, 240 of 1846 (13.0%) received intravenous rehydration, and 67 of 1846 (3.6%) were hospitalized. The following were independently associated with intravenous rehydration: higher Clinical Dehydration Scale score (mild to moderate vs none, odds ratio [OR], 8.73; 95% CI, 5.81-13.13; and severe vs none, OR, 34.15; 95% CI, 13.45-86.73); country (US vs Canada, OR, 6.76; 95% CI, 3.15-14.49); prior health care visit with intravenous fluids (OR, 4.55; 95% CI, 1.32-15.72); and frequency of vomiting (per 5 episodes, OR, 1.66; 95% CI, 1.39-1.99). The following were independently associated with hospitalization: higher Clinical Dehydration Scale score (mild to moderate vs none, OR, 11.10; 95% CI, 5.05-24.38; and severe vs none, OR, 23.55; 95% CI, 7.09-78.25) and country (US vs Canada, OR, 3.37; 95% CI, 1.36-8.40). Oral ondansetron was associated with reduced odds of intravenous rehydration (OR, 0.21; 95% CI, 0.13-0.32) and hospitalization (OR, 0.44; 95% CI, 0.21-0.89). Conclusions and relevance Intravenous rehydration and hospitalization were associated with clinical evidence of dehydration and lack of an oral ondansetron-supported oral rehydration period. Strategies focusing on oral ondansetron administration followed by oral rehydration therapy in children with dehydration may reduce the reliance on intravenous rehydration and hospitalization. Trial registration ClinicalTrials.gov Identifiers: NCT01853124 (PERC) and NCT01773967 (PECARN).

Background Understanding gender gaps in trainee evaluations is critical because these may ultimately determine the duration of training. Currently, no studies describe the influence of gender on the evaluation of pediatric emergency medicine (PEM) fellows. Objective The objective of our study was to compare milestone scores of female versus male PEM fellows. Methods This is a multicenter retrospective cohort study of a national sample of PEM fellows from July 2014 to June 2018. Accreditation Council for Medical Education (ACGME) subcompetencies are scored on a 5-point scale and span six domains: patient care (PC), medical knowledge, systems-based practice, practice-based learning and improvement, professionalism, and interpersonal and communication skills (ICS). Summative assessments of the 23 PEM subcompetencies are assigned by each program's clinical competency committee and submitted semiannually for each fellow. Program directors voluntarily provided deidentified ACGME milestone reports. Demographics including sex, program region, and type of residency were collected. Descriptive analysis of milestones was performed for each year of fellowship. Multivariate analyses evaluated the difference in scores by sex for each of the subcompetencies. Results Forty-eight geographically diverse programs participated, yielding data for 639 fellows (66% of all PEM fellows nationally); sex was recorded for 604 fellows, of whom 67% were female. When comparing the mean milestone scores in each of the six domains, there were no differences by sex in any year of training. When comparing scores within each of the 23 subcompetencies and correcting the significance level for comparison of multiple milestones, the scores for PC3 and ICS2 were significantly, albeit not meaningfully, higher for females. Conclusion In a national sample of PEM fellows, we found no major differences in milestone scores between females and males.

Background: Despite the popular belief that probiotics are most efficacious when treating acute childhood diarrhea if started early and when symptoms are more severe, the data supporting these assumptions are unclear. We sought to evaluate whether the efficacy of probiotics depends on the duration and severity of diarrhea prior to treatment. Methods: This was a pre-planned secondary analysis of two randomized placebo-controlled trials in children 3-48 months of age with acute gastroenteritis, conducted in sixteen emergency departments in North America evaluating the efficacy of two probiotic products. Participants were categorized in severity groups according to the duration (< 24h, 24 – < 72h, and ≥ 72h) and the frequency of diarrhea episodes in the 24 hours (≤ 3, 4 – 5 and ≥ 6) prior to presentation. We used regression models to assess the interaction between pre-treatment diarrhea severity groups and treatment arm (probiotic or placebo) on the presence of moderate-to-severe gastroenteritis defined by a Modified Vesikari Scale score ≥9. Secondary outcomes included diarrhea frequency and duration, unscheduled healthcare provider visits and hospitalization. Findings: 1,770 children were included, 882 (50%) received a probiotic. The development of moderate-to-severe gastroenteritis symptoms following the initiation of treatment did not differ between groups [probiotic - 18.4% (162/882) vs. placebo - 18.3% (162/888); RR 1.00; 95%CI: 0.87, 1.16; P=0.95]. There was no evidence of interaction between baseline severity and treatment (P=0.61) for the primary or any of the secondary outcomes: diarrhea duration (P=0.88), maximum diarrheal episodes in a 24 hour period (P=0.87), unscheduled health care visits (P=0.21) and hospitalization (P=0.87). Interpretation: In children 3 to 48 months with acute gastroenteritis the lack of effect of probiotics is not explained by the duration of symptoms or frequency of diarrheal episodes prior to presentation.

Background The ACGME Milestone Project is a competency-based assessment tool. Subcompetencies (SC) are scored on a 5-point scale, and level 4 is recommended for graduation. The 2018 Milestones Report found that across subspecialties, not all graduates are attaining a level 4 for every SC. Objective To describe the number of pediatric emergency medicine (PEM) fellows who achieve level 4 in all 23 SC at graduation and to identify SC and predictive factors where a level 4 is not achieved. Design/Methods This is a multicenter, retrospective cohort study of PEM fellows. Program directors provided de-identified milestone reports from 2015-2018. Descriptive analysis of milestone scores at graduation was performed. Demographics were compared between fellows who did and did not meet level 4 at graduation for each SC. Sub-analyses assessed differences in residency and first year milestone scores and the rate of milestone attainment between fellows who did and did not attain level 4 at graduation. Results Data from 48 PEM fellowship programs yielded graduation scores for 392 fellows (62% of total). 87% completed pediatric residency and 60% were female. Residency scores were available for 45 fellows. There were no SC in which all fellows attained at least level 4 at graduation; the range of fellows scoring Conclusion In our sample, 67% of PEM fellows did not attain level 4 for at least 1 of the 23 SC at graduation. Low scores during residency or early in fellowship may predict difficulty in meeting level 4 by fellowship completion.

Background Although oral rehydration therapy is recommended for children with acute gastroenteritis (AGE) with none to some dehydration, intravenous (IV) rehydration is still commonly administered to these children in high-income countries. IV rehydration is associated with pain, anxiety, and emergency department (ED) revisits in children with AGE. Objectives We sought to better understand the factors associated with IV rehydration in children with AGE in order to inform knowledge translation strategies. Design/Methods This was a planned secondary analysis of the Pediatric Emergency Research Canada (PERC) and Pediatric Emergency Care Applied Research Network (PECARN) randomized, controlled trials of oral probiotics in children with AGE-associated diarrhea. Eligible children were aged 3–48 months and reported >3 watery stools in a 24-hour period. The primary outcome was administration of IV rehydration at the index ED visit. We used mixed-effects logistic regression model to explore univariable and multivariable relationships between IV rehydration and a prioririsk factors. Results From the parent study sample of 1848 participants, 1846 had data available for analysis: mean (SD) age of 19.1 ± 11.4 months, 45.4% females. 70.2% (1292/1840) vomited within 24 hours of the index ED visit and 34.1% (629/1846) received ondansetron in the ED. 13.0% (240/1846) were administered IV rehydration at the index ED visit, and 3.6% (67/1842) were hospitalized. Multivariable predictors of IV rehydration were Clinical Dehydration Scale (CDS) score [compared to none: mild to moderate (OR: 8.1, CI: 5.5–11.8); severe (OR: 45.9, 95% CI: 20.1–104.7), P Conclusion Higher CDS scores, antiemetic use, previous healthcare visits and country were independent predictors of IV rehydration which was also associated with increased ED revisits. Knowledge translation focused on optimizing the use of antiemetics (i.e. for those with dehydration) and reducing the geographic variation in IV rehydration use may improve the ED experience and reduce ED-revisits.

This article is the last in a 7-part series that aims to comprehensively describe the current state and future directions of pediatric emergency medicine fellowship training from the essential requirements to considerations for successfully administering and managing a program to the careers that may be anticipated on program completion. This article focuses on the many career paths as educators, researchers, advocates, innovators, consultants, administrators, and leaders available to pediatric emergency medicine physicians, in both clinical and nonclinical realms, and how fellows and junior faculty can enrich and prolong their careers through diversification.

This article is the second in a 7-part series that aims to comprehensively describe the current state and future directions of pediatric emergency medicine (PEM) fellowship training from the essential requirements to considerations for successfully administering and managing a program to the careers that may be anticipated upon program completion. This article describes the development of PEM entrustable professional activities (EPAs) and the relationship of these EPAs with existing taxonomies of assessment and learning within PEM fellowship. It summarizes the field in concepts that can be taught and assessed, packaging the PEM subspecialty into EPAs.

Background In 2013, the ACGME implemented the Milestones as a competency-based evaluation framework, spanning the continuum from novice to expert. Some subcompetencies from residency programs were adopted into subspecialty subcompetencies with the same 5-point scores. ACGME Milestones reports indicate lower achievement in identical subcompetencies for first year Pediatric Emergency Medicine (PEM) fellows compared with graduating pediatric residents. While differences between residency and fellowship programs exist, it is unclear why demonstrated skills would be “lost” by residents transitioning to PEM fellowship as suggested by lower milestones scores. Aim To investigate the trajectory of milestone scores from residency to PEM fellowship. Methods We completed a multicenter retrospective cohort study of a national sample of PEM fellows. Participating programs submitted de-identified Milestones data for PEM fellows (2015-2018). Of 23 PEM subcompetencies, 10 were adopted from pediatric and 7 from EM residency subcompetencies. We compared first year PEM fellow performance for these 17 subcompetencies to end-of-residency performance, using Wilcoxon signed rank tests to evaluate the difference in fellows paired scores. A 1-point decline in milestone score was deemed a priori to be clinically significant. Results We collected data for 639 PEM fellows from 48 fellowships. End-of-residency scores were available for 218 fellows from 42 programs. Most (210/218, 96%) completed pediatric residencies; 8 (4%) completed EM training. Declines in median milestones scores between end-of-residency and first year of PEM fellowship were observed for all fellows. These declines were statistically significant for pediatric-trained fellows; clinically significant declines were seen in two subcompetencies (Table 1). Conclusions Our study found significant declines across adopted pediatric subcompetencies for pediatric residency graduates assessed early in their PEM fellowships. It is unclear whether this observed decline in achievement represents a true loss of skills, or a reset of faculty expectations and variance of Milestones interpretation by fellowships. Future studies are warranted to examine whether Milestones accurately assess trainee development across the continuum, or if they are applied differently as physicians transition from residency to subspecialty training.

Background Residents are undertrained to perform acute pediatric sexual abuse evaluations. The American Academy of Pediatrics has proposed development of an adaptable child abuse curriculum, though no such curriculum exists. Objectives Our goal was to perform a needs assessment for pediatric residents performing acute sexual abuse evaluations in an emergency department setting, thus laying groundwork for an adaptable curriculum. The objective was to explore pediatric resident training, knowledge, confidence, expectations, learning needs, and educational goals. Participants and Setting We conducted a qualitative exploratory study of pediatric residents, faculty, and program directors at two academic health centers in New York City. Methods Using purposive and convenience sampling, we conducted focus groups and semi-structured interviews until saturation of ideas was achieved. Through an iterative process using constructivist grounded theory, themes were organized into a curricular model. Results We conducted 3 resident focus groups (n = 21) and 7 interviews with emergency medicine, pediatric, and child abuse faculty. Themes emerged in three categories: barriers (e.g., knowledge deficits), facilitators (e.g., pre-learning), and educational goals. Despite recognizing the importance and increased availability of subspecialists, participants supported gradual autonomy for pediatric residents in the evaluation of suspected sexual abuse, with a goal of independent competency in history and examination skills, and supervised competency of forensic evidence collection. Conclusions Our data support a multimodal, blended curriculum for the acute sexual abuse evaluation, including: (1) asynchronous pre-learning; (2) live workshops; (3) reference tools; and (4) modeled clinical experiences. Our proposed curricular model may be utilized by a variety of frontline clinicians.

BackgroundAcute gastroenteritis develops in millions of children in the United States every year, and treatment with probiotics is common. However, data to support the use of probiotics in this population are limited.MethodsWe conducted a prospective, randomized, double-blind trial involving children 3 months to 4 years of age with acute gastroenteritis who presented to one of 10 U.S. pediatric emergency departments. Participants received a 5-day course of Lactobacillus rhamnosus GG at a dose of 1×1010 colony-forming units twice daily or matching placebo. Follow-up surveys were conducted daily for 5 days and again 14 days after enrollment and 1 month after enrollment. The primary outcome was moderate-to-severe gastroenteritis, which was defined as an illness episode with a total score on the modified Vesikari scale of 9 or higher (scores range from 0 to 20, with higher scores indicating more severe disease), within 14 days after enrollment. Secondary outcomes included the duration and frequency of diarrhea and vomiting, the duration of day-care absenteeism, and the rate of household transmission (defined as the development of symptoms of gastroenteritis in previously asymptomatic household contacts).ResultsAmong the 971 participants, 943 (97.1%) completed the trial. The median age was 1.4 years (interquartile range, 0.9 to 2.3), and 513 participants (52.9%) were male. The modified Vesikari scale score for the 14-day period after enrollment was 9 or higher in 55 of 468 participants (11.8%) in the L. rhamnosus GG group and in 60 of 475 participants (12.6%) in the placebo group (relative risk, 0.96; 95% confidence interval, 0.68 to 1.35; P=0.83). There were no significant differences between the L. rhamnosus GG group and the placebo group in the duration of diarrhea (median, 49.7 hours in the L. rhamnosus GG group and 50.9 hours in the placebo group; P=0.26), duration of vomiting (median, 0 hours in both groups; P=0.17), or day-care absenteeism (median, 2 days in both groups; P=0.67) or in the rate of household transmission (10.6% and 14.1% in the two groups, respectively; P=0.16).ConclusionsAmong preschool children with acute gastroenteritis, those who received a 5-day course of L. rhamnosus GG did not have better outcomes than those who received placebo.

The aim of this study was to assess the validity of a formative feedback instrument for leaders of simulated resuscitations.This is a prospective validation study with a fully crossed (person × scenario × rater) study design. The Concise Assessment of Leader Management (CALM) instrument was designed by pediatric emergency medicine and graduate medical education experts to be used off the shelf to evaluate and provide formative feedback to resuscitation leaders. Four experts reviewed 16 videos of in situ simulated pediatric resuscitations and scored resuscitation leader performance using the CALM instrument. The videos consisted of 4 pediatric emergency department resuscitation teams each performing in 4 pediatric resuscitation scenarios (cardiac arrest, respiratory arrest, seizure, and sepsis). We report on content and internal structure (reliability) validity of the CALM instrument.Content validity was supported by the instrument development process that involved professional experience, expert consensus, focused literature review, and pilot testing. Internal structure validity (reliability) was supported by the generalizability analysis. The main component that contributed to score variability was the person (33%), meaning that individual leaders performed differently. The rater component had almost zero (0%) contribution to variance, which implies that raters were in agreement and argues for high interrater reliability.These results provide initial evidence to support the validity of the CALM instrument as a reliable assessment instrument that can facilitate formative feedback to leaders of pediatric simulated resuscitations.

Introduction Acute gastroenteritis (AGE) is a common and burdensome condition that affects millions of children worldwide each year. Currently available strategies are limited to symptomatic management, treatment and prevention of dehydration and infection control; no disease-modifying interventions exist. Probiotics, defined as live microorganisms beneficial to the host, have shown promise in improving AGE outcomes, but existing studies have sufficient limitations such that the use of probiotics cannot currently be recommended with confidence. Here we present the methods of a large, rigorous, randomised, double-blind placebo-controlled study to assess the effectiveness and side effect profile of Lactobacillus rhamnosus GG (LGG) (ATCC 53103) in children with AGE. Methods and analysis The study is being conducted in 10 US paediatric emergency departments (EDs) within the federally funded Pediatric Emergency Care Applied Research Network, in accordance with current SPIRIT and CONSORT statement recommendations. We will randomise 970 children presenting to participating EDs with AGE to either 5 days of treatment with LGG (1010colony-forming unit twice a day) or placebo between July 2014 to December 2017. The main outcome is the occurrence of moderate-to-severe disease over time, as defined by the Modified Vesikari Scale. We also record adverse events and side effects related to the intervention. We will conduct intention-to-treat analyses and use an enrichment design to restore the statistical power in case the presence of a subpopulation with a substantially low treatment effect is identified. Ethics and dissemination Institutional review board approval has been obtained at all sites, and data and material use agreements have been established between the participating sites. The results of the trial will be published in peer-reviewed journals. A deidentified public data set will be made available after the completion of all study procedures. Trial registration number NCT01773967.

Our objective is to highlight recent literature investigating low-radiation diagnostic strategies in the evaluation of pediatric trauma.In the area of minor head injury, research has focused on implementation of validated clinical decision rules into practice to reduce unnecessary computed tomography scans. Clinical observation may also serve as an adjunct to initial assessment and a potential substitute for computed tomography imaging. Subgroups of children with special needs or severe injury mechanisms may also be safely characterized by the clinical decision rule and spared radiation exposure. Physical examination techniques may be useful in diagnosing mandibular fractures. In addition, evidence suggests that plain radiography for evaluation of blunt thoracic trauma may be sufficient in many cases, and computed tomography could be reserved for those with abnormal radiographs, high-risk mechanisms, or abnormal physical findings. Clinical decision rules are able to predict intra-abdominal injury with high sensitivity. Data suggest that skeletal surveys may be modified to limit radiation exposure in the case of suspected nonaccidental trauma.More research is needed in development of pediatric-specific clinical decision rules and risk stratification and in testing low-radiation diagnostic modalities in the pediatric trauma population.

The burden of acute gastroenteritis (AGE) in US children is substantial. Research into outpatient treatment strategies has been hampered by the lack of easily used and validated gastroenteritis severity scales relevant to the populations studied. We sought to evaluate, in a US cohort, the reliability, construct validity, and generalizability of a gastroenteritis severity scale previously derived in a Canadian population, the modified Vesikari score (MVS).We conducted a prospective, cohort, clinical observational study of children 3 to 48 months of age with acute gastroenteritis presenting to 5 US emergency departments. A baseline MVS score was determined in the emergency department, and telephone follow-up 14 days after presentation was used to assign the follow-up MVS. We determined reliability using inter-item correlations; construct validity via principal component factor analysis; cross-sectional construct validity via correlations with the presence of dehydration, hospitalization, and day care and parental work absenteeism; and generalizability via score distribution among sites.Two hundred eighteen of 274 patients (80%) were successfully contacted for follow-up. Cronbach α was 0.63, indicating expectedly low internal reliability because of the multidimensional properties of the MVS. Factor analysis supported the appropriateness of retaining all variables in the score. Disease severity correlated with dehydration (P0.001), hospitalization (P0.001), and subsequent day care (P = 0.01) and work (P0.001) absenteeism. The MVS was normally distributed, and scores did not differ among sites.The MVS effectively measures global severity of disease and performs similarly in varying populations within the US health care system. Its characteristics support its use in multisite outpatient clinical trials.

We present data from recently conducted research on the diagnosis and management of skin and soft tissue infections (SSTIs) in children.Current research in the area of SSTIs (cellulitis and abscess) has focused on the use of ultrasound, risk factors associated with bacteremia, antibiotic choice, and incision and drainage (ID) practices. When clinical examination is equivocal at distinguishing abscess from cellulitis, ultrasound can aid in the diagnosis and alter management. Bacteremia is rare in immunocompetent children with uncomplicated SSTIs; blood cultures may be reserved for complicated cases and for those who are systemically ill. Despite the increased prevalence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), ID without antibiotics remains the first-line therapy for abscess. Antibiotics for uncomplicated cellulitis should target β-hemolytic streptococci and methicillin-susceptible S. aureus (MSSA). There are significant variations in pain and sedation practices for ID, with substantive evidence for the use of topical anesthetics. Wound packing after ID may not confer significant benefit.Evidence to aid in the diagnosis and management of SSTIs in children has emerged in recent years; however, larger prospective pediatric studies are needed.

In this review, we present and summarize data from recently conducted research regarding controversial aspects of the management of children with bronchiolitis. These data suggest that chronic medical history, gestational age at birth, postnatal age, and physiological variables can identify those children at higher risk for a more severe course of bronchiolitis. Large prospective studies also suggest that the likelihood of significant bacterial illness in febrile infants with bronchiolitis may be lower than in children without bronchiolitis. Nevertheless, urinary tract infections remain relatively common in young febrile children with bronchiolitis. Lastly and unfortunately, the data note a relative lack of effective therapies for children with bronchiolitis, although certain therapies such as systemic corticosteroids show potential efficacy and are in need of further study. The remaining uncertainty surrounding many issues pertaining to bronchiolitis highlight the need for more research aimed to: (1) develop prognostic models to identify patients at risk for a more severe clinical course, (2) develop generalizable diagnostic models to identify febrile infants with bronchiolitis at high and very low risk of significant bacterial illness, and (3) evaluate the effectiveness of promising therapies.

Objectives: To prospectively determine the test characteristics of the 3-view abdominal radiograph to decrease the likelihood of ileocolic intussusception. Methods: We conducted a prospective cross-sectional study of children aged 3 months to 3 years suspected of having intussusception at a children’s hospital emergency department. Clinicians obtained supine, prone, and left lateral decubitus radiographs. We determined the presence or absence of intussusception by air enema, ultrasound, operative report, or clinical follow-up. A masked pediatric radiologist reviewed all radiographs. The criteria evaluated were whether air was visualized in the ascending colon on each view and in the transverse colon on the supine view. Results: Nineteen (14.8%) of 128 patients had intussusception. Using air in the ascending colon on all 3 views as the diagnostic criteria, the test characteristics of the 3-view radiograph were sensitivity, 100% (95% confidence interval [CI], 79.1Y100); specificity, 17.4% (95% CI, 11.1Y26.1); negative predictive value, 100% (95% CI, 79.1Y100); and likelihood ratio of a negative test, 0. When 2 or more of 3 views had air in the ascending colon, sensitivity decreased to 89.5% (95% CI, 75.7Y100) and specificity improved to 45.0% (95% CI, 35.6Y54.3). Air in the transverse colon had moderate sensitivity, 84.2% (95% CI, 67.8Y100), but further improved specificity, 63.3% (95% CI, 54.2Y72.4). Conclusions: The presence of air in the ascending colon on the 3-view abdominal radiograph can decrease the likelihood of or exclude intussusception. When clinical suspicion is low, the presence of specific criterion on a 3-view abdominal radiograph series may obviate the need for further studies.

Objectives The Accreditation Council for Graduate Medical Education mandates pediatric emergency medicine (PEM) fellowships to incorporate medical care cost teaching into the curriculum; however, there are no studies evaluating cost awareness of PEM fellows. Our objectives were to evaluate cost education during fellowship and assess fellows’ knowledge and attitudes regarding costs. Methods We conducted an anonymous electronic survey of US PEM fellows in April-June 2009. Results We received 161 (63%) of 253 responses. Respondents represented all 3 years of training and all regions of the United States. Asked if the Accreditation Council for Graduate Medical Education requires cost education, 35% responded no, and 44% were uncertain. More than 80% of fellows reported no formal cost education. More than 65% believed physicians should receive cost education during fellowship, and 75% felt the current amount of education is insufficient. Results Pediatric emergency medicine fellows showed low accuracy and considerable variability when estimating costs of tests and medications. Median fellows’ estimate for a complete blood count was $50 (interquartile range, $55), where actual cost is $32. Only 23% were within 25% of the true cost. Similarly, the proportions of fellows estimating within 25% of actual cost were small for electrolytes (10%), blood culture (12%), and erythrocyte sedimentation rate (22%). The same held true for the following medications: trimethoprim-sulfamethoxazole (28%), Cefdinir (31%), and cefixime (10%). Ability to predict costs did not improve with year of training. Conclusions Pediatric emergency medicine fellows report little formal teaching on cost issues, and their ability to estimate costs is poor. However, they are receptive to more education on this important issue.

PURPOSE OF REVIEW: We present data from recently conducted research regarding the diagnosis of blunt cervical spine injury (CSI) in children. RECENT FINDINGS: Research in the prehospital setting to evaluate the need for cervical spine immobilization in children, regardless of clinical findings or mechanism of injury, suggests that low-risk prediction rules may be safely utilized by prehospital providers, although more data is needed. Their size, developing skeleton and unique anatomy leave children vulnerable to particular injury patterns, namely cephalad bony fractures and ligamentous and spinal cord injuries without radiographic abnormality. Low-risk clinical prediction rules have been developed but need to be further validated. For those children at higher risk of CSI, diagnostic imaging strategies are evolving, with computed tomography and MRI becoming more prominent. SUMMARY: Evidence in the management of children with CSI has expanded in recent years, but further large prospective studies are needed. We present a review of some recent developments influencing clinical practice. Language: en

To determine the test characteristics of the 3-view abdominal radiograph series to exclude intussusception in children presenting to the pediatric emergency department.We performed a single-center retrospective review of children for whom supine, prone, and lateral decubitus abdominal radiographs were performed as part of our standard diagnostic evaluation for intussusception. A pediatric radiologist masked to the patient's clinical data and outcome reviewed all radiographs. The criterion evaluated was whether air was visualized in the ascending colon on each of the 3 radiograph views. We determined the presence or absence of intussusception hierarchically by definitive radiological study report, surgical operative note, or clinical outcome.We analyzed 179 patients, of whom 27 (15.1%) were diagnosed with intussusception. The test characteristics of the 3-view radiograph series in the diagnosis of intussusception when all 3 views had air in the ascending colon were sensitivity of 100% (95% confidence interval [CI] 87-100), specificity of 18.4% (95% CI, 12.3-24.6), likelihood ratio for a negative test of 0 (95% CI, 0.01-1.53), and negative predictive value (NPV) of 100% (lower bound 95% CI, 98%). When at least 2 views had air in the ascending colon, the test characteristics were sensitivity of 96.3% (95% CI, 89.2-100), specificity of 41.4% (95% CI, 33.6-49.3), likelihood ratio for a negative test of 0.09 (0.01-0.62), and NPV of 98.4 (95% CI, 95.2-100).Using specific criteria, the presence of air in the ascending colon on 2 or 3 abdominal radiograph views has the potential to substantially decrease the likelihood of or exclude intussusception.

We present data from recently conducted research regarding controversial aspects of the evaluation and management of children with minor blunt head trauma.Clinicians frequently but at times indiscriminately perform computed tomography scans for children with minor blunt head trauma resulting in potentially harmful radiation exposure. Recent guidelines recognize the limited but increasing data available to make strong recommendations regarding appropriate neuroimaging decisions. Investigators have derived and validated clinical prediction models to accurately identify patients with substantial traumatic brain injury, though no clear definitive rule exists. Children younger than 2 years appear to have a higher risk of intracranial injury following minor head trauma. These patients can be difficult to assess, with the evidence suggesting the need for a more conservative approach to diagnostic imaging. We present current and accepted definitions of concussion along with risk factors and treatment for postconcussion syndrome. Current return-to-play guidelines suggest that athletes who have sustained concussion should not resume play until symptoms have resolved because of the possibility, though rare, of second impact syndrome.Research in the management of children with minor head trauma is actively evolving. We present a review of recent developments that can influence current clinical practice.
