RESUMEN
OBJECTIVES: Early shock reversal is crucial to improve patient outcomes. Capillary refill time (CRT) is clinically important to identify and monitor shock in children but has issues with inconsistency. To minimize inconsistency, we evaluated a CRT monitoring system using an automated compression device. Our objective was to determine proper compression pressure in children. METHODS: Clinician force for CRT was collected during manual CRT measurement as a reference for automated compression in a previous study (12.9 N, 95% confidence interval, 12.5-13.4; n = 454). An automated compression device with a soft inflation bladder was fitted with a force sensor. We evaluated the effectiveness of the automated pressure to eliminate pulsatile blood flow from the distal phalange. Median and variance of CRT analysis at each pressure was compared. RESULTS: A comparison of pressures at 300 to 500 mm Hg on a simulated finger yielded a force of 5 to 10 N, and these pressures were subsequently used for automated compression for CRT. Automated compression was tested in 44 subjects (median age, 33 months; interquartile range [IQR], 14-56 months). At interim analysis of 17 subjects, there was significant difference in the waveform with residual pulsatile blood flow (9/50: 18% at 300 mm Hg, 5/50:10% at 400 mm Hg, 0/51: 0% at 500 mm Hg, P = 0.008). With subsequent enrollment of 27 subjects at 400 and 500 mm Hg, none had residual pulsatile blood flow. There was no difference in the CRT: median 1.8 (IQR, 1.06-2.875) in 400 mm Hg vs median 1.87 (IQR, 1.25-2.8325) in 500 mm Hg, P = 0.81. The variance of CRT was significantly larger in 400 mm Hg: 2.99 in 400 mm Hg vs. 1.35 in 500 mm Hg, P = 0.02, Levene's test. Intraclass correlation coefficient for automated CRT was 0.56 at 400 mm Hg and 0.78 at 500 mm Hg. CONCLUSIONS: Using clinician CRT measurement data, we determined either 400 or 500 mm Hg is an appropriate pressure for automated CRT, although 500 mm Hg demonstrates superior consistency.

This work shows the electrochemical performance of sputter-deposited, binder-free lithium cobalt oxide thin films with an alumina coating deposited via atomic layer deposition for use in lithium-metal-based microbatteries. The Al2O3 coating can improve the charge-discharge kinetics and suppress the phase transition that occurs at higher potential limits where the crystalline structure of the lithium cobalt oxide is damaged due to the formation of Co4+, causing irreversible capacity loss. The electrochemical performance of the thin film is analysed by imposing 4.2, 4.4 and 4.5 V upper potential limits, which deliver improved performances for 3 nm of Al2O3, while also highlighting evidence of Al doping. Al2O3-coated lithium cobalt oxide of 3 nm is cycled at 147 µA cm-2 (~2.7 C) to an upper potential limit of 4.4 V with an initial capacity of 132 mAh g-1 (65.7 µAh cm-2 µm-1) and a capacity retention of 87% and 70% at cycle 100 and 400, respectively. This shows the high-rate capability and cycling benefits of a 3 nm Al2O3 coating.

STUDY OBJECTIVE: We sought to describe the tracheal intubation technique across a network of children's hospitals and explore the association between intubation technical adjuncts and first-attempt success as well as between laryngoscopy duration and the incidence of hypoxemia. METHODS: We conducted a prospective observational study in 4 tertiary pediatric emergency departments of the Videography in Pediatric Resuscitation Collaborative. Children undergoing tracheal intubation captured on video were eligible for inclusion. Data on intubator background, patient characteristics, technical characteristics (eg, use of videolaryngoscopy and apneic oxygenation), and procedural outcomes were obtained through a video review. RESULTS: We obtained complete data on first attempts in 494 patients. The first-attempt success rate was 67%, the median laryngoscopy duration was 35 seconds (interquartile range 25 to 40), and hypoxemia occurred in 15% of the patients. Videolaryngoscopy was used for at least a part of the procedure in 48% of the attempts, and it had no association with success or the incidence of hypoxemia. Attempts in which videolaryngoscopy was used for the entire procedure (compared with direct laryngoscopy for the entire procedure) had a longer duration (the difference between the medians was 6 seconds; 95% confidence interval, 1 to 12 seconds). Intubation attempts longer than 45 seconds had a greater incidence of hypoxemia (29% versus 6%). Furthermore, apneic oxygenation was used in 8% of the first attempts. CONCLUSION: Among children undergoing tracheal intubation in a group of pediatric emergency departments, first-attempt success occurred in 67% of the patients. Videolaryngoscopy use was associated with longer laryngoscopy durations but was not associated with success or the incidence of hypoxemia.

BACKGROUND: Procedural sedation (PS) is commonly performed in emergency departments (EDs) by nonanesthesiologists. Although adverse events (AEs) are rare, providers must possess the clinical skills to react in a timely manner. We previously described residents' experience and confidence in PS as part of a needs assessment. We found that their ability to perform important clinical tasks as a result of the usual training experience demonstrates educational needs. We developed an educational intervention to address the deficiencies uncovered during our needs assessment. OBJECTIVE: To evaluate the effectiveness of an educational intervention on pediatric residents' clinical performance and confidence when faced with an AE during a simulated PS. METHODS: This was a prospective observational cohort study of residents at a tertiary care children's hospital. All ED attending physicians and fellows were trained in uniform delivery of the educational intervention, which was delivered extemporaneously at the bedside ("Just-in-Time" [JIT]) to all residents performing PS on actual patients in the pediatric ED, over the course of 1 year. Subjects completed the following both before and after the educational intervention: a survey pertaining to confidence in PS, followed by a standardized, video-recorded simulated PS complicated by apnea and desaturation. Clinical performance was evaluated and assessed both in real time and by a video-rater blinded to participants' year of training. We summarized baseline resident characteristics, confidence questionnaire item rankings and success in both the preparation and AE tasks. We compared successful task completion and time to task completion before and after intervention. RESULTS: Forty residents completed both the PRE and POST phases of the study. There was significant improvement in the proportion of residents who completed both preparation and AE tasks after the JIT training. Specifically, there was a significant improvement in the proportion of residents who performed positive-pressure ventilation to treat an apneic event associated with desaturation during the PS (P = 0.007). Residents' confidence scores also significantly improved after the training. CONCLUSION: A brief JIT training in the pediatric ED improves resident clinical performance and confidence when faced with an AE during a simulated PS. Future direction includes correlating this improved performance with patient outcomes in PS.

OBJECTIVES: Personal protective equipment (PPE) is worn by health care providers (HCPs) to protect against hazardous exposures. Studies of HCPs performing critical resuscitation tasks in PPE have yielded mixed results and have not evaluated performance in care of children. We evaluated the impacts of PPE on timeliness or success of emergency procedures performed by pediatric HCPs. METHODS: This prospective study was conducted at 2 tertiary children's hospitals. For session 1, HCPs (medical doctors and registered nurses) wore normal attire; for session 2, they wore full-shroud PPE garb with 2 glove types: Ebola level or chemical. During each session, they performed clinical tasks on a patient simulator: intubation, bag-valve mask ventilation, venous catheter (IV) placement, push-pull fluid bolus, and defibrillation. Differences in completion time per task were compared. RESULTS: There were no significant differences in medical doctor completion time across sessions. For registered nurses, there was a significant difference between baseline and PPE sessions for both defibrillation and IV placement tasks. Registered nurses were faster to defibrillate in Ebola PPE and slower when wearing chemical PPE (median difference, -3.5 vs 2 seconds, respectively; P < 0.01). Registered nurse IV placement took longer in Ebola and chemical PPE (5.5 vs 42 seconds, respectively; P < 0.01). After the PPE session, participants were significantly less likely to indicate that full-body PPE interfered with procedures, was claustrophobic, or slowed them down. CONCLUSIONS: Personal protective equipment did not affect procedure timeliness or success on a simulated child, with the exception of IV placement. Further study is needed to investigate PPE's impact on procedures performed in a clinical care context.

OBJECTIVES: We aimed to quantify time performing chest compressions (CCs) per year of individual providers in a pediatric ED and to project a rate of opportunity for CC based on median clinical hours per provider category. METHODS: This was an observational study of video-recorded resuscitations in a pediatric ED over 1 year. Events where CCs were performed for more than 2 minutes were included. Identification of providers and duration of CCs per provider were determined by video review. Time of CCs was totaled per provider over the study period. Data were expressed as median and interquartile range (IQR). Rate of opportunity for providing CC to a child was calculated by dividing the median clinical hours per year per provider type by the number of CC events per year. RESULTS: Twenty-three CC events totaling 340 minutes of CCs were analyzed. Chest compressions were performed by 6 (13%) of 45 attending physicians, 3 (25%) of 12 fellows, 32 (22%) of 143 nurses, and 19 (59%) of 32 technicians. The median amount of time performing CC was 182 seconds (IQR, 91-396 seconds); by provider category, median amount of time was as follows: attending physicians, 83 seconds (IQR, 64-103 seconds); fellows, 45 seconds (IQR, 6-83 seconds); nurses, 128 seconds (IQR, 93-271 seconds); and technicians, 534 seconds (IQR, 217-793 seconds). The projected hours needed for an opportunity to perform CCs was 730 hours (91 shifts) for attending physicians, 243 hours (30 shifts) for fellows, and 1460 hours (121 shifts) for nurses and technicians. CONCLUSIONS: Performing CCs on children in the ED is a rare event, with a median of 3 minutes per provider per year. Future studies should determine training methods to optimize readiness for these rare occurrences.

OBJECTIVES: High-quality clinical research of resuscitations in a pediatric emergency department is challenging because of the limitations of traditional methods of data collection (chart review, self-report) and the low frequency of cases in a single center. To facilitate valid and reliable research for resuscitations in the pediatric emergency department, investigators from 3 pediatric centers, each with experience completing successful single-center, video-based studies, formed the Videography In Pediatric Emergency Research (VIPER) collaborative. METHODS: Our initial effort was the development of a multicenter, video-based registry and simulation-based testing of the feasibility and reliability of the VIPER registry. Feasibility of data collection was assessed by the frequency of an indeterminate response for all data elements in the registry. Reliability was assessed by the calculation of Cohen κ for dichotomous data elements and intraclass correlation coefficients for continuous data elements. RESULTS: Video-based data collection was completed for 8 simulated pediatric resuscitations, with at least 2 reviewers per case. Data were labeled as indeterminate by at least 1 reviewer for 18 (3%) of 524 relevant data fields. The Cohen κ for all dichotomous data fields together was 0.81 (95% confidence interval, 0.61-1.0). For all continuous (time-based) variables combined, the intraclass correlation coefficient was 0.88 (95% confidence interval, 0.70-0.96). CONCLUSIONS: Initial simulation-based testing suggests video-based data collection using the VIPER registry is feasible and reliable. Our next step is to assess feasibility and reliability for actual pediatric resuscitations and to complete several prospective, hypothesis-based studies of specific aspects of resuscitative care, including of cardiopulmonary resuscitation, tracheal intubation, and teamwork and communication.

OBJECTIVES: This study aimed to determine whether personal protective equipment (PPE) results in deterioration in chest compression (CC) quality and greater fatigue for administering health care providers (HCPs). METHODS: In this multicenter study, HCPs completed 2 sessions. In session 1 (baseline), HCPs wore normal attire; in session 2, HCPs donned full PPE. During each session, they performed 5 minutes of uninterrupted CCs on a child manikin. Chest compression rate, depth, and release velocity were reported in ten 30-second epochs. Change in CC parameters and self-reported fatigue were measured between the start and 2- and 5-minute epochs. RESULTS: We enrolled 108 HCPs (prehospital and in-hospital providers). The median CC rate did not change significantly between epochs 1 and 10 during baseline sessions. Median CC depth and release velocity decreased for 5 minutes with PPE. There were no significant differences in CC parameters between baseline and PPE sessions in any provider group. Median fatigue scores during baseline sessions were 2 (at start), 4 (at 2 minutes), and 6 (at 5 minutes). There was a significantly higher median fatigue score between 0 and 5 minutes in both study sessions and in all groups. Fatigue scores were significantly higher for providers wearing PPE compared with baseline specifically among prehospital providers. CONCLUSIONS: During a clinically appropriate 2-minute period, neither CC quality nor self-reported fatigue worsened to a significant degree in providers wearing PPE. Our data suggest that Pediatric Basic Life Support recommendations for CC providers to switch every 2 minutes need not be altered with PPE use.

The formula for survival in resuscitation describes educational efficiency and local implementation as key determinants in survival after cardiac arrest. Current educational offerings in the form of standardized online and face-to-face courses are falling short, with providers demonstrating a decay of skills over time. This translates to suboptimal clinical care and poor survival outcomes from cardiac arrest. In many institutions, guidelines taught in courses are not thoughtfully implemented in the clinical environment. A current synthesis of the evidence supporting best educational and knowledge translation strategies in resuscitation is lacking. In this American Heart Association scientific statement, we provide a review of the literature describing key elements of educational efficiency and local implementation, including mastery learning and deliberate practice, spaced practice, contextual learning, feedback and debriefing, assessment, innovative educational strategies, faculty development, and knowledge translation and implementation. For each topic, we provide suggestions for improving provider performance that may ultimately optimize patient outcomes from cardiac arrest.

PURPOSE OF REVIEW: The pediatric resuscitation environment is a high-stakes, environment in which a multidisciplinary team must work together with patient outcomes dependent, at least in part, on the performance of that team. Given constraints of the environment and the nature of these events, quality improvement work in pediatric resuscitation can be challenging. Ongoing collection of accurate and reliable data on team performance is necessary to inform and evaluate change. RECENT FINDINGS: Despite the relative difficulty of quality improvement analysis and intervention implementation in the resuscitation environment, these efforts can have significant impact on patient outcomes. Although there are barriers to accurate data collection in real-life resuscitation, team performance of both technical and nontechnical skills can be reliably measured in video-based quality improvement programs. Training of nontechnical skills, using crisis resource management principles, can improve care delivery in resuscitation. SUMMARY: Striving toward a learning healthcare system model in resuscitation care delivery can allow for efficient performance improvement. Given the possible impacts on mortality and quality of life of care delivered in the resuscitation environment, all providers who could possibly face a resuscitation event - no matter how rare - should consider how they are evaluating the quality of their care delivery in this arena.

OBJECTIVES: To describe the frequency, characteristics, and outcomes of heart failure-related emergency department (ED) visits in pediatric patients. We aimed to test the hypothesis that these visits are associated with higher admission rates, mortality, and resource utilization. STUDY DESIGN: A retrospective analysis of the Nationwide Emergency Department Sample for 2010 of patients ≤18 years of age was performed to describe ED visits with and without heart failure. Cases were identified using International Classification of Disease, Ninth Revision, Clinical Modification codes and assessed for factors associated with admission, mortality, and resource utilization. RESULTS: Among 28.6 million pediatric visits to the ED, there were 5971 (0.02%) heart failure-related cases. Heart failure-related ED patients were significantly more likely to be admitted (59.8% vs 4.01%; OR 35.3, 95% CI 31.5-39.7). Among heart failure-related visits, admission was more common in patients with congenital heart disease (OR 5.0, 95% CI 3.3-7.4) and in those with comorbidities including respiratory failure (OR 78.3, 95% CI 10.4-591) and renal failure (OR 7.9, 95% CI 1.7-36.3). Heart failure-related cases admitted to the hospital had a higher likelihood of death than nonheart failure-related cases (5.9% vs 0.32%, P < .001). Factors associated with mortality included respiratory failure (OR 4.5, 95% CI 2.2-9.2) and renal failure (OR 7.8, 95% CI 2.9-20.7). Heart failure-related ED visits were more expensive than nonheart failure-related ED visits ($1460 [IQR $861-2038] vs $778 [IQR $442-1375] [P < .01].) CONCLUSIONS: Heart failure-related visits represent a minority of pediatric ED visits but are associated with increased hospital admission and resource utilization.

OBJECTIVES: To examine technical aspects of pediatric tracheal intubation using video recording and to determine the association between tracheal intubation technique and procedural outcomes. DESIGN: Prospective observational study. SETTING: Emergency department resuscitation bay in single tertiary pediatric center. PATIENTS: Children undergoing emergent tracheal intubation under videorecorded conditions. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A published scoring tool for characterizing patient positioning, intubator kinematics, and adjunctive maneuvers during tracheal intubation was applied to videorecorded pediatric resuscitations when tracheal intubation was performed. Procedural outcomes were measured from video review. Seventy-one children underwent 109 tracheal intubation attempts with an overall first attempt success rate of 69% and a median laryngoscopy duration of 34 seconds (interquartile range, 24-47 s). A significant subset of tracheal intubation attempts were made with the patient's bed at a height below the level of intubator's umbilicus (61%), the patient in a supine position without head elevation (55%), the intubator bent at the waist to greater than 45° (66%), less than 1 cm of mouth opening by the intubator's right hand prior to laryngoscopy (46%), and with the intubator's face less than 12 inches away from the patient's mouth (65%). Adjunctive maneuvers were used in a minority of attempts (cricoid pressure 48%, external laryngeal manipulation 11%, retraction of the right corner of the patient's mouth 26%). On multivariate analysis, including controlling for patient age category and intubator background, retraction of the right corner of the patient's mouth by an assistant showed an independent association with successful tracheal intubation. No other technical aspects were associated with tracheal intubation success. CONCLUSIONS: Intubators commonly exhibited suboptimal technique during tracheal intubation such as bending deeply at the waist, having their eyes close to the patient's mouth, failing to widely open the patient's mouth, and not elevating the occiput in older children. Retraction of the right corner of the patient's mouth by an assistant during laryngoscopy and intubation was associated with TI success.

OBJECTIVE: Capnography is indicated as a guide to assess and monitor both endotracheal intubation and cardiopulmonary resuscitation (CPR). Our primary objective was to determine the effect of the 2010 American Heart Association (AHA) guidelines on the frequency of capnography use during critical events in children in the emergency department (ED). Our secondary objective was to examine associations between patient characteristics and capnography use among these patients. METHODS: A retrospective chart review was performed on children aged 0 to 21 years who were intubated or received CPR in 2 academic children's hospital EDs between January 2009 and December 2012. Age, sex, time of arrival, medical or traumatic cause, length of CPR, return of spontaneous circulation (ROSC), documented use of capnography and colorimetry, capnography values, and adverse events were recorded. RESULTS: Two hundred ninety-two patients were identified and analyzed. Intubation occurred in 95% of cases and CPR in 30% of cases. Capnography was documented in only 38% of intubated patients and 13% of patients requiring CPR. There was an overall decrease in capnography use after publication of the 2010 AHA recommendations (P = 0.05). Capnography use was associated with a longer duration of CPR and return of spontaneous circulation. CONCLUSIONS: Despite the 2010 AHA recommendations, a minority of critically ill children are being monitored with capnography and an unexpected decrease in documented use occurred among our sample. Further education and implementation of capnography should take place to improve the use of this monitoring device for critically ill pediatric patients in the ED.

BACKGROUND: The role of the surveyor in trauma resuscitations is to identify life-threatening injuries and is meant to be conducted by a set protocol for every patient. Optimal performance of the trauma survey is known to be a challenge in pediatric trauma resuscitation. A postulated reason for this observation is that many trainees, such as pediatric residents, who perform the trauma survey have minimal experience and do not have formal advanced trauma life support training. The assessment of factors that may be obstacles in performing the trauma survey has not been studied robustly. OBJECTIVE: The objective of this retrospective cohort study was to use video review of resuscitation of real-life traumatically injured children to (1) describe the characteristics of the trauma patient, the surveyor, and the trauma response team in its current state of function at a tertiary level I trauma center, (2) describe current performance of primary and secondary surveys, as measured by an assessment tool, and (3) determine whether there are specific characteristics associated with reduced quality, completeness, or timeliness of the assessment of an injured child. METHODS: Retrospective review of emergency department (ED) trauma activations captured by video recording between June 2009 and January 2012. Video-recorded resuscitations were reviewed, and survey performance was scored using a novel assessment tool applying a scoring system (0, 1, or 2 points) for each essential element (airway, breathing, circulation, etc.) accounting for quality, sequence, and timing of assessments. Maximum score was 8 points for the primary survey and 22 points for the secondary survey. Time to completion of survey elements was recorded. Chart review identified surveyor characteristics (level of training and type of training program) and patient data fields (age, mechanism of injury, trauma level, Glasgow Coma Score, time of encounter, disposition, and number of procedures). Descriptive statistics and univariate analysis were performed. RESULTS: Of 749 eligible trauma activations, 228 activations were enrolled in the study with complete data for 202 patients. Most activations met level II criteria and involved blunt trauma. Most patients had a Glasgow Coma Score of 15 and were non-ICU inpatient admissions. PGY-3 residents performed the most surveys (53% of surveys done by residents). Pediatric residents performed 46% of surveys; emergency medicine (EM) residents, 41%; and pediatric EM fellows, 6%. Median scores on primary and secondary surveys were 7 and 12, respectively; median time to completion was 82 seconds and 265 seconds, respectively. Only 22% of primary surveys and 0% of secondary surveys were performed completely. Pediatric EM fellows had the highest mean score on primary and secondary survey. Pediatric EM fellows took longest to perform primary survey and shortest to complete secondary survey. Mean scores on primary and secondary survey were not significantly different between pediatric and EM residents (6.7 vs 6.7; 12.5 vs 11.6). There was no association between survey scores and level or type of training. Emergency medicine residents spent less time on the trauma survey, but this difference did not reach statistical significance. CONCLUSIONS: Primary and secondary surveys are frequently performed incompletely and inefficiently regardless of level of training or type of training program. There is no difference in measured performance among different types of residency programs. The impact of trauma resuscitation education on improved survey performance should be studied prospectively.

BACKGROUND: Early detection of compensated pediatric septic shock requires diagnostic tests that are sensitive and specific. Four physical exam signs are recommended for detecting pediatric septic shock prior to hypotension (cold extremities, mental status, capillary refill, peripheral pulse quality); this study tested their ability to detect patients who develop organ dysfunction among a cohort of undifferentiated pediatric systemic inflammatory response syndrome patients. METHODS: A prospective cohort of 239 pediatric emergency department patients <19 years with fever and tachycardia and undergoing phlebotomy were enrolled. Physicians recorded initial physical exams on a standardized form. Abstraction of the medical record determined outcomes including organ dysfunction, intensive care unit stay, serious bacterial infection, and therapies. RESULTS: Organ dysfunction occurred in 13/239 (5.4%) patients. Presence of at least one sign was significantly associated with organ dysfunction (Relative Risk: 2.71, 95% CI: 1.05-6.99), and presence of at least two signs had a Relative Risk = 4.98 (95% CI: 1.82-13.58). The sensitivity of exam findings ranged from 8-54%, specificity from 84-98%. Signs were associated with increased risk of intensive care and fluid bolus, but not with serious bacterial infection, intravenous antibiotics or admission. Altered mental status and peripheral pulse quality were significantly associated with organ dysfunction, while abnormal capillary refill time and presence of cold, mottled extremities were not. CONCLUSIONS: Certain recommended physical exam signs were associated with increased risk of organ dysfunction, a rare outcome in this undifferentiated pediatric population with fever and tachycardia. Sensitivity was low, while specificity was high. Additional research into optimally sensitive and specific diagnostic strategies is needed.

ABSTRACT: This systematic review, following PRISMA standards, aimed to assess the effectiveness of higher versus lower fidelity simulation on health care providers engaged in team training. A comprehensive search from January 1, 2011 to January 24, 2023 identified 1390 studies of which 14 randomized (n = 1530) and 5 case controlled (n = 257) studies met the inclusion criteria. The certainty of evidence was very low due to a high risk of bias and inconsistency. Heterogeneity prevented any metaanalysis. Limited evidence showed benefit for confidence, technical skills, and nontechnical skills. No significant difference was found in knowledge outcomes and teamwork abilities between lower and higher fidelity simulation. Participants reported higher satisfaction but also higher stress with higher fidelity materials. Both higher and lower fidelity simulation can be beneficial for team training, with higher fidelity simulation preferred by participants if resources allow. Standardizing definitions and outcomes, as well as conducting robust cost-comparative analyses, are important for future research.
