RESUMEN
OBJECTIVE: Methods currently used to triage patients from mass casualty events have a sparse evidence basis. The objective of this project was to assess gaps of the widely used Simple Triage and Rapid Transport (START) algorithm using a large database when it is used to triage low-acuity patients. Subsequently, we developed and tested evidenced-based improvements to START. METHODS: Using the National Trauma Database (NTDB), a large set of trauma victims were assigned START triage levels, which were then compared to recorded patient mortality outcomes using area under the receiver-operator curve (AUC). Subjects assigned to the "Minor/Green" level who nevertheless died prior to hospital discharge were considered mistriaged. Recursive partitioning identified factors associated with of these mistriaged patients. These factors were then used to develop candidate START models of improved triage, whose overall performance was then re-evaluated using data from the NTDB. This process of evaluating performance, identifying errors, and further adjusting candidate models was repeated iteratively. RESULTS: The study included 322,162 subjects assigned to "Minor/Green" of which 2,046 died before hospital discharge. Age was the primary predictor of under-triage by START. Candidate models which re-assigned patients from the "Minor/Green" triage level to the "Delayed/Yellow" triage level based on age (either for patients >60 or >75), reduced mortality in the "Minor/Green" group from 0.6% to 0.1% and 0.3%, respectively. These candidate START models also showed net improvement in the AUC for predicting mortality overall and in select subgroups. CONCLUSION: In this research model using trauma registry data, most START under-triage errors occurred in elderly patients. Overall START accuracy was improved by placing elderly but otherwise minimally injured-mass casualty victims into a higher risk triage level. Alternatively, such patients would be candidates for closer monitoring at the scene or expedited transport ahead of other, younger "Minor/Green" victims.

Exertional heat stroke incidence is on the rise and has become the third leading cause of death in high school athletes. It is entirely preventable, yet this is a case of a 15-year-old, 97-kg male football player who presented unresponsive and hyperthermic after an August football practice. His blood pressure was 80/30, and his pulse was 180. He had a rectal temperature of 107.3°F, and upon entering the emergency department, he was rapidly cooled in 40 minutes. As he progressed, he developed metabolic acidosis, elevated liver enzymes, a prolapsed mitral valve with elevated troponin levels, and worsening hypotension even with extracorporeal membrane oxygenation support. After 3 days in the hospital, this young man was pronounced dead as a result of complications from exertional heat stroke. We address not only the complications of his hospital course relative to his positive blood cultures but also the complications that can result from attention-deficit/hyperactivity disorder medication our patient was taking. As the population of young adults becomes more obese and more highly medicated for attention-deficit/hyperactivity disorder, we sought out these growing trends in correlation with the increase in incidence of heat-related illness. We also address the predisposing factors that make young high school athletes more likely to experience heat illness and propose further steps to educate this susceptible population.

OBJECTIVE: The objective of this study was to compare the duration of analgesia, need for analgesic medications, and pain-related nursing interventions in patients who did and did not receive ultrasound-guided femoral nerve blocks for femur fracture pain. METHODS: This is a retrospective, preimplementation and postimplementation cohort study. An emergency department log of patients receiving femoral nerve blocks for femur fracture pain was compared with a similar cohort of patients with femur fractures who did not receive nerve blocks. The primary outcome is time from initial pain treatment until the next dose of analgesic. Data were analyzed using Kaplan-Meier methods. Secondary outcomes include number of doses of pain medication, total amount of morphine given, and number of pain-related nursing interventions. Data were analyzed with the Mann-Whitney U test. RESULTS: Eighty-one patients met inclusion/exclusion criteria: 50 in the preimplementation cohort and 31 in the postimplementation group. The median times until next dose of analgesic medication were 2.2 hours (interquartile range [IQR], 1.2-3.4 hours) in the preimplementation group and 6.1 hours (IQR, 3.8-9.5 hours) in the postimplementation group (P < 0.001). The median numbers of doses of pain medication were 0.3 per hour (IQR, 0.25-0.5 per hour) in the preimplementation group and 0.15 per hour (IQR, 0.07-0.3 per hour) in the postimplementation group. The median total doses of morphine were 14.8 µg/kg per hour (IQR, 9.4-19.2 µg/kg per hour) in the preimplementation group and 6.5 µg/kg per hour (IQR, 0-12.2 µg/kg per hour) in the postimplementation group (P = 0.01). The median numbers of nursing interventions were 0.4 per hour (IQR, 0.25-0.5 per hour) in the preimplementation group and 0.15 per hour (IQR, 0.1-0.2 per hour) in the postimplementation group (P < 0.001). CONCLUSIONS: Patients who received ultrasound-guided femoral nerve block for femur fracture pain had longer duration of analgesia, required fewer doses of analgesic medications, and needed fewer nursing interventions than those receiving systemic analgesic medication alone.

BACKGROUND: Recent studies reviewing immune mechanisms of immune thrombocytopenia (ITP) have suggested acute and chronic forms may represent distinct immunopathological disorders. This study evaluated absolute lymphocyte counts (ALCs) as predictors for ITP outcomes. PROCEDURE: CBCs with differential counts were ascertained at presentation, 3, 6, and 12 months for 204 patients. Receiver operating characteristic (ROC) curves were used to determine cutoff values. Logistic regression models and recursive partitioning were used to evaluate which variables were significantly associated with outcomes. RESULTS: ALC values at presentation were not independently predictive of disease duration. However, ALC values at 3 months were significant predictors. Sixty-eight percent (40/59) of patients >8 years of age and 43% (20/46) of patients ≤ 8 years who had an ALC ≤ 3,000/µl at 3 months developed chronic ITP. This compares to chronic rates of only 25% (3/12) and 2% (2/87) of patients >8 and ≤ 8 years, respectively, with an ALC > 3,000/µl at 3 months. Further, 92% (60/65) of patients who developed chronic ITP had a 3-month ALC ≤ 3,000/µl. An ALC > 3,000/µl at 3 months is a strong predictor for platelet recovery as only 5% (5/99) of these patients developed chronic ITP. CONCLUSION: This study suggests progression to lower lymphocyte counts over the first few months of disease is a strong predictor for chronic ITP, allowing for risk stratification of patients, particularly when used in conjunction with other known predictors. Further research is needed to confirm these findings and to fully investigate the pathophysiological mechanisms responsible for this association.

STUDY OBJECTIVE: A variety of methods have been proposed and used in disaster triage situations, but there is little more than expert opinion to support most of them. Anecdotal disaster experiences often report mediocre real-world triage accuracy. The study objective was to determine the accuracy of several disaster triage methods when predicting clinically important outcomes in a large cohort of trauma victims. METHODS: Pediatric, adult, and geriatric trauma victims from the National Trauma Data Bank were assigned triage levels, using each of 6 disaster triage methods: simple triage and rapid treatment (START), Fire Department of New York (FDNY), CareFlight, Glasgow Coma Scale (GCS), Sacco Score, and Unadjusted Sacco Score. Methods for approximating triage systems were vetted by subject matter experts. Triage assignments were compared against patient mortality at hospital discharge with area under the receiver operator curve. Secondary outcomes included death in the emergency department, use of a ventilator, and lengths of stay. Subgroup analysis assessed triage accuracy in patients by age, trauma type, and sex. RESULTS: In this study, 530,695 records were included. The Sacco Score predicted mortality most accurately, with area under the receiver operator curve of 0.883 (95% confidence interval 0.880 to 0.885), and performed well in most subgroups. FDNY was more accurate than START for adults but less accurate for children. CareFlight was best for burn victims, with area under the receiver operator curve of 0.87 (95% confidence interval 0.85 to 0.89) but mistriaged more salvageable trauma patients to "dead/black" (41% survived) than did other disaster triage methods (≈10% survived). CONCLUSION: Among 6 disaster triage methods compared against actual outcomes in trauma registry patients, the Sacco Score predicted mortality most accurately. This analysis highlighted comparative strengths and weakness of START, FDNY, CareFlight, and Sacco, suggesting areas in which each might be improved. The GCS predicted outcomes similarly to dedicated disaster triage strategies.

OBJECTIVE: The objective of this study was to determine the predictive value of the Glasgow coma scale (GCS) and the Glasgow motor component (GMC) for overall mortality, death on arrival, and major injury and the relationship between GCS and length of stay (LOS) in the emergency department (ED) and hospital. METHODS: Records from the American College of Surgeons National Trauma Data Base from 2007 to 2009 were extracted. Patients 0 to 18 years old transported from a trauma scene with complete initial scene data were included. Statistical analysis, including construction of receiver-operator curves, determined the correlation between GCS, GMC, and the clinical outcomes of interest. RESULTS: There were 104,035 records with complete data for analysis, including 3946 deaths. Mean patient age was 12.6 (SD, 5.5) years. Glasgow coma scale was predictive of overall mortality, with area under the receiver-operator curve (AUC) of 0.946 (95% confidence interval [CI], 0.941-0.951); death on arrival, with AUC of 0.958 (95% CI, 0.953-0.963); and risk of major injury, with AUC of 0.720 (0.715-0.724). Lower GCS scores were associated with shorter ED LOS and longer hospital stays (P <0.001, analysis of variance) except GCS 3, associated with shorter hospitalizations. For predicting overall mortality, the AUC for GMC was 0.940 (95% CI, 0.935-0.945), and for predicting major injury, the AUC was 0.681 (95% CI, 0.677-0.686). CONCLUSIONS: For pediatric trauma victims, the GCS is predictive of mortality and injury outcomes, as well as both ED and hospital LOS, and has excellent prognostic accuracy. The GMC has predictive value for injury and mortality that is nearly equivalent to the full GCS.

INTRODUCTION: Though many mass-casualty triage methods have been proposed, few have been validated in an evidence-based manner. The Sacco Triage Method (STM) has been shown to accurately stratify adult victims of blunt and penetrating trauma into groups of increasing mortality risk. However, it has not been validated for pediatric trauma victims. PURPOSE: Evaluate the STM's performance in pediatric trauma victims. METHODS: Records from the United States' National Trauma Data Base, a registry of trauma victims developed by the American College of Surgeons, were extracted for the 2007-2009 reporting years. Patients ≤ 18 years of age transported from a trauma scene with complete initial scene data were included in the analysis. Sacco triage scores were assigned to each registry patient, and receiver-operator curves were developed for predicting mortality, along with several secondary outcomes. Area under the receiver-operator curve (AUC) was the main outcome statistic. Sensitivity analysis was performed using a Sacco score without age adjustment, using blunt versus penetrating trauma, and using patients <12 years of age. RESULTS: There were 210,175 pediatric records, of which 90,037 had complete data for analysis. The STM with age adjustment predicted pediatric trauma mortality with an AUC of 0.933 (95% CI: 0.925-0.940). Without the age adjustment term, it predicted mortality with an AUC of 0.924 (95% CI: 0.916-0.933). The STM with age adjustment predicted blunt trauma mortality in 72,467 patients with an AUC of 0.938 (95% CI: 0.929-0.947) and penetrating trauma mortality in 10,099 patients with an AUC of 0.927 (95% CI: 0.911-0.943). These findings did not change significantly when analysis was limited to patients <12 years of age. The Sacco Triage Method was also predictive of some secondary outcomes, such as major injury and death on arrival to the emergency department. CONCLUSION: The Sacco Triage Method, with or without its age adjustment term, was a highly accurate predictor of mortality in pediatric trauma patients in this registry database. This triage method appears to be a valid strategy for the prioritization of injured children.

QUESTION: I prescribe oral steroids for children in my community when they suffer asthma exacerbation. How many doses of steroids are recommended? Do all children need to take steroids for 5 days? ANSWER: Traditionally, mild-to-moderate pediatric asthma exacerbations have been treated with a short course of oral steroids-often 5 days of prednisone or prednisolone. However, recent evidence suggests a similar outcome can be acheived with a single dose of dexamethasone, which has a longer half-life and powerful anti-inflammatory effects, along with easier administration and compliance. Single-dose dexamethasone offers a simple and reliable treatment for these patients in office, urgent care, and emergency department settings.

INTRODUCTION: It remains unclear which mass-casualty incident (MCI) triage tool best predicts outcomes for child disaster victims. STUDY OBJECTIVES: The primary objective of this study was to compare triage outcomes of Simple Triage and Rapid Treatment (START), modified START, and CareFlight in pediatric patients to an outcomes-based gold standard using the Criteria Outcomes Tool (COT). The secondary outcomes were sensitivity, specificity, under-triage, over-triage, and overall accuracy at each level for each MCI triage algorithm. METHODS: Singleton trauma patients under 16 years of age with complete prehospital, emergency department (ED), and in-patient data were identified in the 2007-2009 National Trauma Data Bank (NTDB). The COT outcomes and procedures were translated into ICD-9 procedure codes with added timing criteria. Gold standard triage levels were assigned using the COT based on outcomes, including mortality, injury type, admission to the hospital, and surgical procedures. Comparison triage levels were determined based on algorithmic depictions of the three MCI triage tools. RESULTS: A total of 31,093 patients with complete data were identified from the NTDB. The COT was applied to these patients, and the breakdown of gold standard triage levels, based on their actual clinical outcomes, was: 17,333 (55.7%) GREEN; 11,587 (37.3%) YELLOW; 1,572 (5.1%) RED; and 601 (1.9%) BLACK. CareFlight had the best sensitivity for predicting COT outcomes for BLACK (83% [95% confidence interval, 80%-86%]) and GREEN patients (79% [95% CI, 79%-80%]) and the best specificity for RED patients (89% [95% CI, 89%-90%]). CONCLUSION: Among three prehospital MCI triage tools, CareFlight had the best performance for correlating with outcomes in the COT. Overall, none of three tools had good test characteristics for predicting pediatric patient needs for surgical procedures or hospital admission.

OBJECTIVE: Previous literature suggests that process-related factors (eg, time of day, patient volume) and patient-related factors (eg, acuity, socioeconomic status) are associated with premature departure from emergency departments. We sought to evaluate the relationship of these and other factors with premature departure in a large, unselected cohort of pediatric emergency department patients. METHODS: This study was a retrospective cohort analysis of visits to a single tertiary site during a 1-year period. Patients' zip codes determined assignment of census-based socioeconomic metrics. Multivariate regression identified factors associated with premature departure. Sensitivity and subset analyses were performed. Return visits within 48 hours after premature departure were also reviewed. RESULTS: There were 46,417 visits, of which 2164 were premature departures. In multivariate analysis, independent predictors of premature departures were arrival time, arrival month, arrival day of week, patient acuity, concurrent premature departures, arrival rate, arrival period average length of stay, and poverty rate. Aside from patient acuity and poverty rate, no patient-related factors were significant in multivariate analysis. These results were robust in sensitivity analysis across different multivariate models. Among premature departures, there were 120 return visits (5.5%), of which 15 were admitted (0.7%). There were no deaths. Acuity was similar between initial and subsequent visits. CONCLUSIONS: Process-related factors and individual patient acuity have the strongest influence on premature departure from the pediatric emergency department. Health care organizations concerned with premature departure should focus efforts on improving pediatric emergency process flow.

BACKGROUND: Currently, approximately 85% of children with significant congenital heart problems survive to adolescence and adulthood. This survival rate represents a dramatic improvement in the medical and surgical care of congenital heart disease (CHD) during the last 35 years. Nevertheless, these patients remain at increased risk for significant cardiac problems long after primary interventions are completed. They are more likely than the general population to seek urgent medical care, often in an emergency department setting. They represent a new and growing population of emergency department patients with a specialized set of problems not traditionally part of the training for emergency medicine (EM) physicians. OBJECTIVE: We investigated the current scope and status of training for EM physicians in the immediate management of CHD patients as they grow to adolescence and adulthood. METHODS: We conducted 2 cross-sectional surveys to assess the current training environment for 2 specific groups: (1) US general EM (GEM) residency programs, and (2) US and Canadian pediatric EM (PEM) fellowship programs. Surveys were mailed to program directors during the summer of 2005. A total of 198 surveys were sent out: 134 to GEM residency directors and 64 to PEM fellowship directors. RESULTS: The response rate overall was 68%, with a 64% response rate from the GEM residency directors and 77% from the PEM fellowship directors. Across all programs, 43% (56/130 respondents) were "unsure" about the existence or location of an adult CHD (ACHD) clinic in their area. When asked to rate the importance of ACHD as a training topic, 40 (85%) of 47 PEM fellowship directors and 62 (74%) of 84 GEM residency directors ranked it as "low priority" or "unnecessary." However, 70 (55%) of 127 respondents were "unsure," "uncomfortable," or "worried" about the ACHD training their trainees receive (PEM, 59%; GEM, 53%). In addition, most program directors (75%) estimated that their trainees care for 5 or fewer ACHD patients annually. CONCLUSIONS: There seems to be a mismatch between the growing need for ACHD emergency care and the current state of this topic in both GEM residency and PEM fellowship training programs.

The purpose of this study was to prospectively determine the neurodevelopmental effects associated with single-suture, nonsyndromic craniosynostosis before and after surgery. Children diagnosed with single-suture craniosynostosis were evaluated by a psychologist using the Bayley Scales of Infant Development-Second Edition (BSID-II) within 2 months before and again 1 year after surgical correction. The BSID-II is a widely used measure of infant cognitive and motor development. The scale consists of three parts, the Mental Developmental Index (MDI), the Psychomotor Developmental Index (PDI), and the Behavior Rating Scale. The MDI and PDI yield age-standard scores (mean, 100; SD, 16). The children ranged in age from 2.5 to 10 months at the time of the craniofacial reconstruction (average age, 5.9 months). Metopic synostosis was diagnosed in 23 percent, sagittal synostosis in 45 percent, and unilateral coronal synostosis in 32 percent of patients. Twenty-two patients were evaluated preoperatively, of whom 15 patients were evaluated postoperatively. Mean baseline BSID-II scores revealed a mild delay in mental and motor scores (MDI, 82.3; PDI, 79.5). Mean postoperative BSID-II scores still revealed a mild delay in mental scores but significantly improved motor scores (MDI, 79.3; PDI, 89.3). Of the 15 children, four (27 percent) had BSID-II evaluations that were in the average range for all scales and nine infants (60 percent) had at least one MDI or PDI score in the significantly delayed range (<70). Among children with single-suture nonsyndromic craniosynostosis, mean Bayley scores indicated mild baseline deficits in both mental and motor scores. After surgical treatment, improvement was seen in the motor scale. It appears from this sample that neurodevelopmental abnormalities may be present in children with single-suture synostosis, and some may persist at 1 year of follow-up.

OBJECTIVE: To investigate the demographic and clinical factors of children who present to the pediatric emergency department (ED) with abdominal pain and their outcomes. METHODS: A review of the electronic medical record of patients 1 to 18 years old, who presented to the Children's Hospital of Pittsburgh ED with a complaint of abdominal pain over the course of 2 years, was conducted. Demographic and clinical characteristics, as well as visit outcomes, were reviewed. Subjects were grouped by age, race, and gender. Results of evaluation, treatment, and clinical outcomes were compared between groups by using multivariate analysis and recursive partitioning. RESULTS: There were 9424 patient visits during the study period that met inclusion and exclusion criteria. Female gender comprised 61% of African American children compared with 52% of white children. Insurance was characterized as private for 75% of white and 37% of African American children. A diagnosis of appendicitis was present in 1.9% of African American children and 5.1% of white children. Older children were more likely to be admitted and have an operation associated with their ED visit. Appendicitis was uncommon in younger children. Constipation was commonly diagnosed. Multivariate analysis by diagnosis as well as recursive partitioning analysis did not reflect any racial differences in evaluation, treatment, or outcome. CONCLUSIONS: Constipation is the most common diagnosis in children presenting with abdominal pain. Our data demonstrate that no racial differences exist in the evaluation, treatment, and disposition of children with abdominal pain.

OBJECTIVE: Asthma is one of the most common childhood illnesses and accounts for a substantial amount of pediatric emergency department visits. Historically, acute exacerbations are treated with a beta agonist via nebulizer therapy (NEB). However, with the advent of the spacer, the medication can be delivered via a metered dose inhaler (MDI+S) with the same efficacy for mild-to-moderate asthma exacerbations. To date, no study has been done to evaluate emergency department (ED) length of stay (LOS) and opportunity cost between nebulized vs MDI+S. The objective of this study was to compare ED LOS and associated opportunity cost among children who present with a mild asthma exacerbation according to the delivery mode of albuterol: MDI+S vs NEB. METHODS: A structured, retrospective cross-sectional study was conducted. Medical records were reviewed from children aged 1-18 years treated at an urban pediatric ED from July 2007 to June 2008 with a discharge diagnosis International Classification of Disease-9 of asthma. Length of stay was defined: time from initial triage until the time of the guardian signature on the discharge instructions. An operational definition was used to define a mild asthma exacerbation; those patients requiring only one standard weight based albuterol treatment. Emergency department throughput time points, demographic data, treatment course, and delivery method of albuterol were recorded. RESULTS: Three hundred and four patients were analyzed: 94 in the MDI+S group and 209 in the NEB group. Mean age in years for the MDI+S group was 9.57 vs 5.07 for the NEB group (p<0.001). The percentage of patients that received oral corticosteroids was 39.4% in the MDI+S group vs 61.7% in the NEB group (p<0.001). There was no difference between groups in: race, insurance status, gender, or chest radiographs. The mean ED LOS for patients in the MDI+S group was 170 minutes compared to 205 minutes in the NEB group. On average, there was a 25.1 minute time savings per patient in ED treatment time (p<0.001; 95% CI=3.8-31.7). Significant predictors of outcome for treatment time were chest radiograph, steroids, and treatment mode. Opportunity cost analysis estimated a potential cost savings of $213,532 annually using MDI+S vs NEB. CONCLUSION: In mild asthma exacerbations, administering albuterol via MDI+S decreases ED treatment time when compared to administering nebulized albuterol. A metered dose inhaler with spacer utilization may enhance opportunity cost savings and decrease the left without being seen population with improved throughput. LIMITATIONS: The key limitations of this study include its retrospective design, the proxy non-standard definition of mild asthma exacerbation, and the opportunity cost calculation, which may over-estimate the value of ED time saved based on ED volume.

OBJECTIVES: Approximately 2% to 5% of children presenting to pediatric emergency departments (PEDs) leave prior to a complete evaluation. This study assessed risk factors for premature departure (PD) from a PED to identify key metrics and cutoffs for reducing the PD rate. METHODS: A 3-year cohort (June 2004-May 2007) of children presenting to a PED was evaluated. Children were excluded if they presented for psychiatric issues, were held awaiting hospital admission in the PED due to a lack of inpatient beds, were more than 21 years old, or died before disposition. Univariate analyses, multivariable logistic regression, and recursive partitioning were used to identify factors associated with PD. A fourth year of data (June 2007-May 2008) was used for validation and sensitivity analysis. RESULTS: There were 132,324 patient visits in the 3-year derivation data set with a 3.8% PD rate, and 45,001 visits in the fourth-year validation data set with a 4.3% PD rate. PDs were minimized when average wait time was below 110 minutes, concurrent PDs were fewer than two, and average length of stay (LOS) was less than 224 minutes in the derivation set, with similar results in the validation set. When these metrics were exceeded, PD rates were over 10% among low-acuity patients. These findings were robust across a broad range of assumptions during sensitivity analysis. CONCLUSIONS: The authors identified five key metrics associated with PD in the PED: average wait time, average LOS, acuity, concurrent PDs, and arrival rate. Operational cutoffs for these metrics, determined by recursive partitioning, may be useful to physicians and administrators when selecting specific interventions to address PDs from the PED.

OBJECTIVES: Clavicle fractures are among the most common orthopedic injuries in children. Diagnosis typically involves radiographs, which expose children to radiation and may consume significant time and resources. Our objective was to determine if bedside emergency department (ED) ultrasound (US) is an accurate alternative to radiography. METHODS: This was a prospective study of bedside US for diagnosing clavicle fractures. A convenience sample of children ages 1-18 years with shoulder injuries requiring radiographs was enrolled. Bedside US imaging and an unblinded interpretation were completed by a pediatric emergency physician (EP) prior to radiographs. A second interpreter, a pediatric EP attending physician with extensive US experience, determined a final interpretation of the US images at a later date. This final interpretation was blinded to both clinical and radiography outcomes. The reference standard was an attending radiologist's interpretation of radiographs. The primary outcome was the accuracy of the blinded US interpretation for detecting clavicle fractures compared to the reference standard. Secondary outcome measures included the interrater reliability of the unblinded bedside and the blinded physicians' interpretations and the FACES pain scores (range, 0-5) for US and radiograph imaging. RESULTS: One-hundred patients were included in the study, of whom 43 had clavicle fractures by radiography. The final US interpretation had 95% sensitivity (95% confidence interval [CI] = 83% to 99%) and 96% specificity (95% CI = 87% to 99%), and overall accuracy was 96%, with 96 congruent readings. Positive and negative predictive values (PPVs and NPVs, respectively) were 95% (95% CI = 83% to 99%) and 96% (95% CI = 87% to 99%), respectively. Interrater reliability (kappa) was 0.74 (95% CI = 0.60 to 0.88). FACES pain scores were available for the 86 subjects who were at least 5 years old. Pain scores were similar during US and radiography. CONCLUSIONS: Compared to radiographs, bedside US can accurately diagnose pediatric clavicle fractures. US causes no more discomfort than radiography when detecting clavicle fractures. Given US's advantage of no radiation, pediatric EPs should consider this application.
