Importance The quality of pediatric resuscitative care delivered across the spectrum of emergency departments (EDs) in the United States is poorly described. In a recent study, more than 4000 EDs completed the Pediatric Readiness Survey (PRS); however, the correlation of PRS scores with the quality of simulated or real patient care has not been described. Objective To measure and compare the quality of resuscitative care delivered to simulated pediatric patients across a spectrum of EDs and to examine the correlation of PRS scores with quality measures. Design, Setting, and Participants This prospective multicenter cohort study evaluated 58 interprofessional teams in their native pediatric or general ED resuscitation bays caring for a series of 3 simulated critically ill patients (sepsis, seizure, and cardiac arrest). Main Outcomes and Measures A composite quality score (CQS) was measured as the sum of 4 domains: (1) adherence to sepsis guidelines, (2) adherence to cardiac arrest guidelines, (3) performance on seizure resuscitation, and (4) teamwork. Pediatric Readiness Survey scores and health care professional demographics were collected as independent data. Correlations were explored between CQS and individual domain scores with PRS. Results Overall, 58 teams from 30 hospitals participated (8 pediatric EDs [PEDs], 22 general EDs [GEDs]). The mean CQS was 71 (95% CI, 68-75); PEDs had a higher mean CQS (82; 95% CI, 79-85) vs GEDs (66; 95% CI, 63-69) and outperformed GEDs in all domains. However, when using generalized estimating equations to estimate CQS controlling for clustering of the data, PED status did not explain a higher CQS (β = 4.28; 95% CI, -4.58 to 13.13) while the log of pediatric patient volume did explain a higher CQS (β = 9.57; 95% CI, 2.64-16.49). The correlation of CQS to PRS was moderate (r = 0.51; P < .001). The correlation was weak for cardiac arrest (r = 0.24; P = .07), weak for sepsis (ρ = 0.45; P < .001) and seizure (ρ = 0.43; P = .001), and strong for teamwork (ρ = 0.71; P < .001). Conclusions and Relevance This multicenter study noted significant differences in the quality of simulated pediatric resuscitative care across a spectrum of EDs. The CQS was higher in PEDs compared with GEDs. However, when controlling for pediatric patient volume and other variables in a multivariable model, PED status does not explain a higher CQS while pediatric patient volume does. The correlation of the PRS was moderate for simulation-based measures of quality.

4.8 billion. Adherence to practice guidelines can significantly reduce mortality; however, few methods to compare performance across a spectrum of emergency departments (EDs) have been described. OBJECTIVES We employed standardized, in situ simulations to measure and compare adherence to pediatric sepsis guidelines across a spectrum of EDs. We hypothesized that pediatric EDs (PEDs) would have greater adherence to the guidelines than general EDs (GEDs). We also explored factors associated with improved performance. METHODS This multi-center observational study examined in situ teams caring for a simulated infant in septic shock. The primary outcome was overall adherence to the pediatric sepsis guideline as measured by six subcomponent metrics. Characteristics of teams were compared using multivariable logistic regression to describe factors associated with improved performance. RESULTS We enrolled 47 interprofessional teams from 24 EDs. Overall, 21/47 teams adhered to all six sepsis metrics (45%). PEDs adhered to all six metrics more than GEDs (93% vs. 22%; difference 71%, 95% confidence interval [CI] 43-84). Adherent teams had significantly higher Emergency Medical Services for Children readiness scores, MD composition of physicians to total team members, teamwork scores, provider perceptions of pediatric preparedness, and provider perceptions of sepsis preparedness. In a multivariable regression model, only greater composite team experience had greater adjusted odds of achieving an adherent sepsis score (adjusted odds ratio 1.38, 95% CI 1.01-1.88). CONCLUSIONS Using standardized in situ scenarios, we revealed high variability in adherence to the pediatric sepsis guideline across a spectrum of EDs. PEDs demonstrated greater adherence to the guideline than GEDs; however, in adjusted analysis, only composite team experience level of the providers was associated with improved guideline adherence.

Abstract Background. In disasters, paramedics often triage victims, including children. Little is known about obstacles paramedics face when performing pediatric disaster triage. Objective. To determine obstacles to pediatric disaster triage performance for paramedics enrolled in a simulation-based disaster curriculum. Design. We conducted a qualitative evaluation of paramedics’ self-reported obstacles to pediatric disaster triage performance. The paramedics were enrolled in a pediatric disaster triage curriculum at one of three study sites. An individually administered, semi-structured debriefing was created iteratively, and used after a 10-victim, multiple-family house fire simulation. The debriefings were audio-recorded, and transcribed. Two investigators independently analyzed the transcripts. Using grounded theory strategy, the data were analyzed via 1) immersion and coding of data, 2) clustering of codes to generate themes, and 3) theme-based generation of hypotheses. While analyzing the data, we employed peer debriefing to determine emerging codes, groups, and thematic saturation. Systematically applied data trustworthiness strategies included triangulation and member checking. Results. A total of 34 participants were debriefed, with prehospital care experience ranging from 1 to 25 years of experience. We identified several barriers to pediatric disaster triage: 1) lack of familiarity with children and their physiology, 2) challenges with triaging children with special health-care needs, 3) emotional reactions to triage situations, including a mother holding an injured/dead child, and 4) training limitations, including poor simulation fidelity. Conclusion. Paramedics report particular difficulty triaging multiple child disaster victims due to emotional obstacles, unfamiliarity with pediatric physiology, and struggles with triage rationale and efficiency.

Abstract Objective. There is a need for rigorously designed pediatric disaster triage (PDT) training simulations for paramedics. First, we sought to design three multiple patient incidents for EMS provider training simulations. Our second objective was to determine the appropriate interventions and triage level for each victim in each of the simulations and develop evaluation instruments for each simulation. The final objective was to ensure that each simulation and evaluation tool was free of bias toward any specific PDT strategy. Methods. We created mixed-methods disaster simulation scenarios with pediatric victims: a school shooting, a school bus crash, and a multiple-victim house fire. Standardized patients, high-fidelity manikins, and low-fidelity manikins were used to portray the victims. Each simulation had similar acuity of injuries and 10 victims. Examples include children with special health-care needs, gunshot wounds, and smoke inhalation. Checklist-based evaluation tools and behaviorally anchored global assessments of function were created for each simulation. Eight physicians and paramedics from areas with differing PDT strategies were recruited as Subject Matter Experts (SMEs) for a modified Delphi iterative critique of the simulations and evaluation tools. The modified Delphi was managed with an online survey tool. The SMEs provided an expected triage category for each patient. The target for modified Delphi consensus was ≥85%. Using Likert scales and free text, the SMEs assessed the validity of the simulations, including instances of bias toward a specific PDT strategy, clarity of learning objectives, and the correlation of the evaluation tools to the learning objectives and scenarios. Results. After two rounds of the modified Delphi, consensus for expected triage level was >85% for 28 of 30 victims, with the remaining two achieving >85% consensus after three Delphi iterations. To achieve consensus, we amended 11 instances of bias toward a specific PDT strategy and corrected 10 instances of noncorrelation between evaluations and simulation. Conclusions. The modified Delphi process, used to derive novel PDT simulation and evaluation tools, yielded a high degree of consensus among the SMEs, and eliminated biases toward specific PDT strategies in the evaluations. The simulations and evaluation tools may now be tested for reliability and validity as part of a prehospital PDT curriculum.

OBJECTIVES We aimed to explore whether a) step stool use is associated with improved cardiopulmonary resuscitation (CPR) quality; b) provider adjusted height is associated with improved CPR quality; and if associations exist, c) determine whether just-in-time (JIT) CPR training and/or CPR visual feedback attenuates the effect of height and/or step stool use on CPR quality. METHODS We analysed data from a trial of simulated cardiac arrests with three study arms: No intervention; CPR visual feedback; and JIT CPR training. Step stool use was voluntary. We explored the association between 1) step stool use and CPR quality, and 2) provider adjusted height and CPR quality. Adjusted height was defined as provider height + 23 cm (if step stool was used). Below-average height participants were ≤ gender-specific average height; the remainder were above average height. We assessed for interaction between study arm and both adjusted height and step stool use. RESULTS One hundred twenty-four subjects participated; 1,230 30-second epochs of CPR were analysed. Step stool use was associated with improved compression depth in below-average (female, p=0.007; male, p<0.001) and above-average (female, p=0.001; male, p<0.001) height providers. There is an association between adjusted height and compression depth (p<0.001). Visual feedback attenuated the effect of height (p=0.025) on compression depth; JIT training did not (p=0.918). Visual feedback and JIT training attenuated the effect of step stool use (p<0.001) on compression depth. CONCLUSIONS Step stool use is associated with improved compression depth regardless of height. Increased provider height is associated with improved compression depth, with visual feedback attenuating the effects of height and step stool use.

Objective Acutely ill infants and children presenting to the emergency department are treated by either physicians with pediatric emergency medicine (PEM) training or physicians without PEM training, a good proportion of which are general emergency medicine–trained physicians (GEDPs). This scoping review identified published literature comparing the care provided to infants and children (⩽21 years of age) by PEM-trained physicians to that provided by GEDPs. Methods The search was conducted in 2 main steps as follows: (1) initial literature search to identify available literature with evolving feedback from the group while simultaneously deciding search concepts as well as inclusion and exclusion criteria and (2) modification of search concepts and conduction of search using finalized concepts as well as review and selection of articles for final analysis using set inclusion criteria. Each study was independently assessed by 2 reviewers for eligibility and quality. Data were independently abstracted by reviewers, and authors were contacted for missing data. Results Our search yielded 3137 titles and abstracts. Twenty articles reporting 19 studies were included in the final analysis. The studies were grouped under type of care, diagnostic studies, medication administration, and process of care. The studies addressed differences in the management of fever, croup, bronchiolitis, asthma, urticaria, febrile seizures, and diabetic ketoacidosis. Conclusions This review highlights the lack of robust studies and heterogeneity of literature comparing practice patterns of PEM-trained physicians with GEDPs. We have outlined a systematic approach to reviewing a body of literature for topics that lack clear terms of comparison across studies.

Objectives: Pauses in cardiopulmonary resuscitation negatively impact clinical outcomes; however, little is known about the contributing factors. The objective of this study is to determine the frequency, duration, and causes for pauses during cardiac arrest. Design: This is a secondary analysis of video data collected from a prospective multicenter trial. Twenty-six simulated pediatric cardiac arrest scenarios each lasting 12 minutes in duration were analyzed by two independent reviewers to document events surrounding each pause in chest compressions. Setting: Ten children’s hospitals across Canada, the United, and the United Kingdom. Subjects: Resuscitation teams composed of three healthcare providers trained in cardiopulmonary resuscitation. Interventions: A simulated pediatric cardiac arrest case in a 5 year old. Measurements and Main Results: The frequency, duration, and associated factors for each pause were recorded. Communication was rated using a four-point scale reflecting the team’s shared mental model. Two hundred fifty-six pauses were reviewed with a median of 10 pauses per scenario (interquartile range, 7–12). Median pause duration was 5 seconds (interquartile range, 2–9 s), with 91% chest compression fraction per scenario (interquartile range, 88–94%). Only one task occurred during most pauses (66%). The most common tasks were a change of chest compressors (25%), performing pulse check (24%), and performing rhythm check (15%). Forty-nine (19%) of the pauses lasted greater than 10 seconds and were associated with shock delivery (p < 0.001), performing rhythm check (p < 0.001), and performing pulse check (p < 0.001). When a shared mental model was rated high, pauses were significantly shorter (mean difference, 4.2 s; 95% CI, 1.6–6.8 s; p = 0.002). Conclusions: Pauses in cardiopulmonary resuscitation occurred frequently during simulated pediatric cardiac arrest, with variable duration and underlying causes. A large percentage of pauses were greater than 10 seconds and occurred more frequently than the recommended 2-minute interval. Future efforts should focus on improving team coordination to minimize pause frequency and duration.

Introduction Teamwork training focuses on improving patient outcomes through better communication. Scales exist to assess providers’ perceptions of teamwork; however, they are not designed for use immediately after the care of critically ill patients. Objectives This study aimed to develop a survey to quantify providers’ perceptions of teamwork and task load during critical care resuscitations in a PED and to use the tool to compare physician and nonphysician ratings of resuscitations. Methods Survey items were adapted from validated tools. The resulting survey contained 15 Likert scale items completed by providers immediately after resuscitations. An exploratory factor analysis was conducted. Mixed models, accounting for clustering of providers within resuscitations, tested for systematic differences in responses between physicians and nonphysicians and explored how well the factor scores predicted the overall “smoothness” of the resuscitation. Results Six hundred fifty-four surveys from 169 resuscitations were conducted. The exploratory factor analysis identified 2 factors with 13 items explaining 47% of the overall variance of “teamwork and communication” (Cronbach &agr; = 0.80) and “task load” (Cronbach &agr; = 0.77). There were no differences in factors predicting smoothness between physicians and nonphysicians (P = 0.27). Both were significant positive predictors of the outcome “the resuscitation went smoothly.” Conclusions The Survey of Teamwork and Task Load among Medical Providers was developed to evaluate providers’ perceptions of teamwork immediately after care of critically ill patients in a pediatric emergency department. Items reflect 2 constructs, with good internal consistency. Responses did not vary by professional training, suggesting that it is useful for all providers. Both factors predicted the overall smoothness. Each was useful in predicting the perception that the resuscitation went smoothly.

OBJECTIVE We aimed to describe the differences in workload between team leaders and CPR providers during a simulated pediatric cardiac arrest, to evaluate the impact of a CPR feedback device on provider workload, and to describe the association between provider workload and the quality of CPR. METHODS We conducted secondary analysis of data from a randomized trial comparing CPR quality in teams with and without use of a real-time visual CPR feedback device [1]. Healthcare providers (team leaders and CPR providers) completed the NASA Task Load Index survey after participating in a simulated cardiac arrest scenario. The effect of provider roles and real-time feedback on workload were compared with independent t-tests. RESULTS Team leaders reported higher levels of mental demand, temporal demand, performance-related workload and frustration, while CPR providers reported comparatively higher physical workload. CPR providers reported significantly higher average workload (control 58.5 vs. feedback 62.3; p = 0.035) with real-time feedback provided compared to the group without feedback. Providers with high workloads (average score >60) had an increased percentage of time with guideline-compliant CPR depth versus those with low workloads (average score <60) (p = 0.034). CONCLUSIONS Healthcare providers reported high workloads during a simulated pediatric cardiac arrest. Physical and mental workloads differed based on provider role. CPR providers using a CPR feedback device reported increased average workloads. The quality of CPR improved with higher reported physical workloads.
