9-1-1 Activations from Ambulatory Care Centers: A Sicker Pediatric Population.

BACKGROUND: Pediatric patients transferred by Emergency Medical Services (EMS) from urgent care (UC) and office-based physician practices to the emergency department (ED) following activation of the 9-1-1 EMS system are an under-studied population with scarce literature regarding outcomes for these children. The objectives of this study were to describe this population, explore EMS level-of-care transport decisions, and examine ED outcomes. METHODS: This was a retrospective review of patients zero to <15 years of age transported by EMS from UC and office-based physician practices to the ED of two pediatric receiving centers from January 2017 through December 2019. Variables included reason for transfer, level of transport, EMS interventions and medications, ED medications/labs/imaging ordered in the first hour, ED procedures, ED disposition, and demographics. Data were analyzed with descriptive statistics, X test, point biserial correlation, two-sample z test, Mann-Whitney U test, and 2-way ANOVA. RESULTS: A total of 450 EMS transports were included in this study: 382 Advanced Life Support (ALS) runs and 68 Basic Life Support (BLS) runs. The median patient age was 2.66 years, 60.9% were male, and 60.7% had private insurance. Overall, 48.9% of patients were transported from an office-based physician practice and 25.1% were transported from UC. Almost one-half (48.7%) of ALS patients received an EMS intervention or medication, as did 4.41% of BLS patients. Respiratory distress was the most common reason for transport (46.9%). Supplemental oxygen was the most common EMS intervention and albuterol was the most administered EMS medication. There was no significant association between level of transport and ED disposition (P = .23). The in-patient admission rate for transported patients was significantly higher than the general ED admission rate (P <.001). CONCLUSION: This study demonstrates that pediatric patients transferred via EMS after activation of the 9-1-1 system from UC and medical offices are more acutely ill than the general pediatric ED population and are likely sicker than the general pediatric EMS population. Paramedics appear to be making appropriate level-of-care transport decisions.

Negative Appendectomies: Evaluating Diagnostic Imaging Techniques at General versus Pediatric Emergency Departments.

BACKGROUND: Although appendicitis is the most common pediatric surgical emergency, the path to diagnosis remains equivocal, with utilization of imaging modalities largely institution dependent. OBJECTIVES: Our objective was to compare imaging practices and negative appendectomy rates between patients transferred from nonpediatric hospitals to our pediatric hospital and primary patients presenting directly to our institution. METHODS: We retrospectively reviewed all laparoscopic appendectomy cases performed at our pediatric hospital in 2017 for imaging and histopathologic results. Two-sample z-test was used to examine negative appendectomy rates between transfer and primary patients. The negative appendectomy rates of patients who received different imaging modalities were analyzed using the Fisher's exact test. RESULTS: Of 626 patients, 321 (51%) were transferred from nonpediatric hospitals. The negative appendectomy rate for transfer patients was 6.5% and 6.6% for primary patients (p = 0.99). Ultrasound (US) was the only imaging obtained in 31% of transfer and 82% of primary patients. The negative appendectomy rate of US performed at transfer hospitals compared with our pediatric institution was not significantly different (11% vs. 5%, p = 0.06). Computed tomography (CT) was the only imaging obtained in 34% of transfer and 5% of primary patients. Both US and CT were completed for 17% of transfer and 19% of primary patients. CONCLUSION: The negative appendectomy rates of transfer and primary patients were not significantly different despite more frequent CT use at nonpediatric facilities. It may be valuable to encourage US utilization at adult facilities given the potential to safely reduce CT use in the evaluation of suspected pediatric appendicitis.

A Mixed Methods Needs Assessment for a Debriefing Intervention Following Critical Cases.

OBJECTIVE: The emergency department (ED) is a demanding environment, and critical events have been identified as contributors to stress. Debriefing is a possible intervention for staff, but there is little information regarding formulation and implementation. A needs assessment was conducted to describe the emotions of pediatric ED (PED) staff following critical events and assess opinions regarding debriefing. METHOD: This mixed methods study used convergent design for triangulation. After critical cases, PED staff members were given the Peritraumatic Distress Inventory (PDI). Additionally, a questionnaire with 2 open-ended questions on debriefing was administered. Themes were extracted from the questionnaire using directed content analysis. RESULTS: A total of 719 responses were collected for 142 critical cases. Physical reactions were often endorsed in the PDI, and these reactions were mirrored in the qualitative data, which included physiological responses such as stress, adrenaline high, anxiety, fatigue, and overwhelm. Helplessness and grief were 2 of the emotional PDI items frequently endorsed, which were reflected in the qualitative strand by themes such as helplessness, sadness, disheartenment, and regret. There was considerable variability between critical cases such that not every critical case elicited a desire for a debrief. CONCLUSIONS: PED staff report measurable levels of stress after critical patient cases that warrant follow-up. Formal debriefing immediately after critical patient cases with specific caveats may be valuable for the reduction of stress. Any formal debriefing program will need to balance various goals with attention to the session length, setting, and timing.

Mental Health Revisits at US Pediatric Emergency Departments.

Importance: Pediatric emergency department (ED) visits for mental health crises are increasing. Patients who frequently use the ED are of particular concern, as pediatric mental health ED visits are commonly repeat visits. Better understanding of trends and factors associated with mental health ED revisits is needed for optimal resource allocation and targeting of prevention efforts. Objective: To describe trends in pediatric mental health ED visits and revisits and to determine factors associated with revisits. Design, Setting, and Participants: In this cohort study, data were obtained from 38 US children's hospital EDs in the Pediatric Health Information System between October 1, 2015, and February 29, 2020. The cohort included patients aged 3 to 17 years with a mental health ED visit. Exposures: Characteristics of patients, encounters, hospitals, and communities. Main Outcomes and Measures: The primary outcome was a mental health ED revisit within 6 months of the index visit. Trends were assessed using cosinor analysis and factors associated with time to revisit using mixed-effects Cox proportional hazards regression. Results: There were 308 264 mental health ED visits from 217 865 unique patients, and 13.2% of patients had a mental health revisit within 6 months. Mental health visits increased by 8.0% annually (95% CI, 4.5%-11.4%), whereas all other ED visits increased by 1.5% annually (95% CI, 0.1%-2.9%). Factors associated with mental health ED revisits included psychiatric comorbidities, chemical restraint use, public insurance, higher area measures of child opportunity, and presence of an inpatient psychiatric unit at the presenting hospital. Patients with psychotic disorders (hazard ratio [HR], 1.42; 95% CI, 1.29-1.57), disruptive or impulse control disorders (HR, 1.36; 95% CI, 1.30-1.42), and neurodevelopmental disorders (HR, 1.22; 95% CI, 1.14-1.30) were more likely to revisit. Patients with substance use disorders (HR, 0.60; 95% CI, 0.55-0.66) were less likely to revisit. Conclusions and Relevance: Markers of disease severity and health care access were associated with mental health revisits. Directing hospital and community interventions toward identified high-risk patients is needed to help mitigate recurrent mental health ED use and improve mental health care delivery.

Parental attitudes in the pediatric emergency department about the COVID-19 vaccine.

BACKGROUND: COVID-19 vaccinations are now recommended in the United States (U.S.) for children ≥ 6 months old. However, pediatric vaccination rates remain low, particularly in the Hispanic/Latinx population. OBJECTIVE: Using the 4C vaccine hesitancy framework (calculation, complacency, confidence, convenience), we examined parental attitudes in the emergency department (ED) towards COVID-19 vaccination, identified dimensions of parental vaccine hesitancy, and assessed parental willingness to have their child receive the COVID-19 vaccine. METHODS: As part of a larger multi-methods study examining influenza vaccine hesitancy, we conducted interviews that included questions about COVID-19 vaccine authorization for children. We used directed content analysis to extract qualitative themes from 3 groups of parents in the ED: Hispanic/Latinx Spanish speaking (HS), Hispanic/Latinx English speaking (HE), non-Hispanic/non-Latinx White English speaking (WE). Themes were triangulated with the Parent Attitudes about Childhood Vaccines (PACV) survey, where higher scores indicate increased vaccine hesitancy. RESULTS: Factors influencing vaccine hesitancy were mapped to the 4C framework from 58 sets of interviews and PACVs. HE and HS parents, compared to WE parents, had less knowledge about COVID-19 and its vaccine, and more beliefs in COVID-19 vaccine myths. However, both HS and HE parent groups were more inclined to endorse COVID-19 vaccine effectiveness as a reason to have their children vaccinated. HS parents felt that COVID-19 increased their fear of illnesses in general and were worried about confusing COVID-19 with other infections. Median PACV scores of HS (Mdn = 20) and HE (Mdn = 20) parent groups were higher than of WE parents (Mdn = 10), but parental willingness to have their child receive COVID-19 vaccination was similar across groups. CONCLUSIONS: Higher COVID-19 vaccine hesitancy among HS and HE parents compared to WE parents may be attributed to insufficient knowledge about COVID-19, its vaccine, along with COVID-19 vaccine myths. Efforts to provide targeted vaccine education to different populations is warranted.

Validation of a 3-Dimensional-Printed Infant Tibia for Intraosseous Needle Insertion Training.

INTRODUCTION: Current bone models used for pediatric intraosseous (IO) placement training are expensive or lack anatomic and/or functional fidelity. This technical report describes the development and validation of a 3-dimensional printed (3DP) tibia from a pediatric lower extremity computed tomography scan for IO procedural training. METHODS: Multiple 3DP tibia models were printed using a dual-extrusion fused-filament fabrication printer. Models underwent iterative optimization until 2 final models, one of polypropylene (3DP clear) and the other of polylactic acid/polypropylene (3DP white), were selected. Using an exploratory sequential mixed-methods design, a novel IO bone model assessment tool was generated. Physicians then used the assessment tool to evaluate and compare common IO bone models to the novel 3DP models during IO needle insertion. RESULTS: Thirty physicians evaluated the provided pediatric IO bone models. Compared with a chicken bone as a reference, the 3DP white bone had statistically significantly higher mean scores of anatomy, heft, sense of being anchored in the bone, quality of bone resistance, and "give" when interfaced with an IO needle. Twenty-two of the 30 participants ranked the 3DP white bone as either 1st or 2nd in terms of ranked preference of pediatric IO bone model. A 3DP white bone costs $1.10 to make. CONCLUSIONS: The 3DP IO tibia models created from real-life computed tomography images have high degrees of anatomic and functional realism. These IO training models are easily replicable, highly appraised, and can be printed at a fraction of the cost of commercially available plastic models.

Weighty Matters: A Real-World Comparison of the Handtevy and Broselow Methods of Prehospital Weight Estimation.

INTRODUCTION: The majority of pediatric medications are dosed according to weight and therefore accurate weight assessment is essential. However, this can be difficult in the unpredictable and peripatetic prehospital care setting, and medication errors are common. The Handtevy method and the Broselow tape are two systems designed to guide Emergency Medical Services (EMS) providers in both pediatric patient weight estimation and medication dosing. The accuracy of the Handtevy method of weight estimation as practiced in the field by EMS has not been previously examined. STUDY OBJECTIVE: The primary objective of this study was to examine the field performance of the Handtevy method and the Broselow tape with respect to prehospital patient weight estimation. METHODS: This was a retrospective chart review of trauma and non-trauma patients transported by EMS to the emergency department (ED) of a quaternary care children's hospital from January 1, 2021 through June 30, 2021. Demographic data, ED visit information, prehospital weight estimation, and medication dosing were collected and analyzed. Scale-based weight from the ED was used as the standard for comparison. RESULTS: A total of 509 patients <13 years of age were included in this study. The EMS providers using the Broselow method estimated patient weight to within +/-10% of ED scale weight in 51.3% of patients. When using the Handtevy method, the EMS providers estimated patient weight to within +/-10% of ED scale weight in 43.7% of patients. When comparing the Handtevy versus Broselow method of prehospital weight estimation, there was no significant association between method and categorized weight discrepancy (over, under, or accurate estimates - defined as within 10% of ED scale weight; P = .25) or percent weight discrepancy (P = .75). On average, prehospital weight estimation was 6.33% lower than ED weight with use of the Handtevy method and 6.94% lower with use of the Broselow method. CONCLUSION: This study demonstrated no statistically significant difference between the use of the Handtevy or Broselow methods with respect to prehospital weight estimation. While further research is necessary, these results suggest similar field performance of the Broselow and Handtevy methods.

Describing the Patient Population of a Pediatric Emergency Department Based on Visit Frequency.

OBJECTIVE: A small number of children in the United States use a disproportionate share of emergency healthcare services. Our study objective was to examine characteristics associated with frequent pediatric emergency department (PED) utilization. METHODS: A retrospective cohort-sequential study of patients seen in the PED of an urban children's hospital was conducted. Patients were categorized into 2 groups: infrequent users (<4 visits during index year 2017) and frequent users (≥4 visits in 2017). Frequent PED users were further divided into persistent frequent (≥4 visits in the year before and after 2017) and incidental frequent (≥4 visits in 2017). Patient- and visit-level characteristics were analyzed for associations with PED utilization. RESULTS: In 2017, there were 82,361 visits by 56,767 patients to our PED. Frequent users comprised 4% of the total patient volume but accounted for 13% of visits. Compared with infrequent users, frequent users were younger, more likely publicly insured, and English speaking. Frequent user visits were more likely to occur outside clinic hours, be triaged as emergent, and involve subspecialists. Compared with visits by incidental frequent users, visits by persistent frequent users were more likely to be emergent or urgent, and involve subspecialists, diagnostic imaging, laboratory testing, and medication administration. CONCLUSIONS: Although the percentage of frequent users to a PED in 2017 was low, they made up a disproportionate share of total visits. Differences between persistent and incidental frequent PED users suggest that these subgroups may benefit from tailored interventions to reduce frequent PED utilization.

Social Emergency Medicine: Capitalizing on the Pediatric Emergency Department Visit to Screen and Connect Patients and Families to Community Resources.

OBJECTIVE: To describe the social needs of families screened by the Community Health Advocates Team (CHAT) Desk, situated within a pediatric emergency department (PED); and to evaluate the effectiveness of this help desk in connecting families to community resources. METHODS: Trained undergraduates, onsite in the PED 30 hours/week during daytime and evening hours, weekdays and weekends, screened a convenience sample of families of patients in the PED for social needs, and provided information on available community resources. Families were offered a follow-up phone call several weeks after their PED visit to assess program satisfaction and success, and identify remaining social needs. RESULTS: Between January 2019 and March 2020, CHAT Desk screened and assisted 682 families. CHAT routinely provided resources about free outdoor recreational activities for families, but after that, the most commonly provided informational resources pertained to: health care (n = 200), housing (n = 143), and food (n = 137). Of families who completed the follow-up phone call (n = 294), almost half (n = 134, 46%) reported being able to contact at least one of the resources; 100 reported that the resource was able to assist them, and 99 families planned to continue using the resource. When asked about satisfaction, 93% (n = 274) reported being very satisfied or somewhat satisfied with CHAT; 94% (n = 276) said they would recommend it to others. CONCLUSIONS: The PED of a busy tertiary care children's hospital is an opportune location to screen families for social needs, and provide them with information on requested community resources.

Pediatric emergency department shift experiences and moods: An exploratory sequential mixed-methods study.

OBJECTIVE: The objective was to investigate the impact of affective, social, behavioral, and cognitive factors on pediatric emergency department (PED) provider mood changes during clinical shifts, with the introduction of a novel on-shift measure. METHODS: The nominal group technique was used to generate the ED experience survey (EDES), encompassing factors that may influence PED provider mood. Providers were alerted via experience sampling method to complete the EDES and positive and negative affect schedule at randomly generated times. Analyses were conducted using multilevel modeling of moods within shifts within persons. RESULTS: Measures were completed 221 times during 137 shifts by 52 PED providers. Positive mood tended to increase with higher self-rated capacity to deal with challenging patient situations (p < 0.001). Having to repeat patient assessments was negatively associated with positive mood during the beginning, but not rest of shift (p = 0.01). Changes in positive mood varied across provider groups (p < 0.001). Negative mood tended to decrease with higher self-rated quality of interactions with patients/families (p < 0.001). Needing a restroom break during any time on duty was associated with negative mood (p < 0.001). Furthermore, negative mood was associated with the need to process emotions during the shift beginning (p = 0.01). Finally, not knowing about patients' outcomes was associated with negative mood during the shift end (p < 0.001). CONCLUSIONS: PED providers' mood during shifts are impacted by ED-specific factors spanning physical, social, behavioral, affective, and cognitive features. Future research may explore potential entry points for mitigation of clinician stress to support provider well-being and ultimately improve patient care.

Text messages by wireless mesh network vs voice by two-way radio in disaster simulations: A crossover randomized-controlled trial.

BACKGROUND: Communication failures secondary to damaged infrastructure have caused difficulties in coordinating disaster responses. Two-way radios commonly serve as backup communication for hospitals. However, text messaging has become widely adopted in daily life and new technologies such as wireless mesh network (WMN) devices allow for text messaging independent of cellular towers, Wi-Fi networks, and electrical grids. OBJECTIVE: To examine the accuracy of communication using text-based messaging transmitted over WMN devices (TEXT-WMN) compared to voice transmitted over two-way radios (VOICE-TWR) in disaster simulations. Secondary outcomes were patient triage accuracy, perceived workload, and device preference. METHODS: 2 × 2 Latin square crossover design: 2 simulations (each involving 15 min of simulated hospital-wide disaster communication) by 2 modalities (TEXT-WMN and VOICE-TWR). Physicians were randomized to one of two sequences: VOICE-TWR first and TEXT-WMN second; or TEXT-WMN first and VOICE-TWR second. Analyses were conducted using linear mixed effects modeling. RESULTS: On average, communication accuracy significantly improved with TEXT-WMN compared to VOICE-TWR. Communication accuracy also significantly improved, on average, during the second simulation compared to the first. There was no significant change in triage accuracy with either TEXT-WMN or VOICE-TWR; however, triage accuracy significantly improved, on average, during the second simulation compared to the first. On average, perceived workload was significantly lower with TEXT-WMN compared to VOICE-TWR, and was also significantly lower during the second simulation compared to the first. Most participants preferred TEXT-WMN to VOICE-TWR. CONCLUSION: TEXT-WMN technology may be more effective and less burdensome than VOICE-TWR in facilitating accurate communication during disasters.

Assessing the Utility of Urine Testing in Febrile Infants 2 to 12 Months of Age With Bronchiolitis.

BACKGROUND: The utility of testing for urinary tract infection (UTI) in febrile infants with bronchiolitis is indeterminate. OBJECTIVE: The objective of this study was to investigate if the incidence of UTIs in febrile infants 2 to 12 months of age with bronchiolitis is higher than the presumed incidence of asymptomatic bacteriuria and determine risk factors associated with UTIs in this population. METHODS: This prospective multicenter cross-sectional study was conducted in the emergency departments of 6 children's hospitals between November 2011 and June 2015. We obtained a convenience sample of febrile infants with bronchiolitis 2 to 12 months of age who were tested for UTI. Patient characteristics analyzed included age, maximum temperature, duration of fever, ethnicity, sex, and circumcision status. RESULTS: A total of 442 patients (including 86 from a previously published pilot study) were enrolled. Mean age was 5.5 months, 65.2% were Latino, 50.9% were male, and 27.6% of male infants were circumcised. Urinary tract infections were found in 33 patients (7.69%, binomial; 95% confidence interval [CI], 5.19%-10.33%). Urinary tract infections were not related to age, height of temperature, duration of fever, or ethnicity. Uncircumcised males were significantly more likely to have UTIs than circumcised males (7.64% vs 0%, P = 0.03). Odds ratios (ORs) were lower for circumcised males but not uncircumcised males when compared with females (OR, 0.12; CI, 0.0-0.71; P = 0.01 vs OR, 0.77; CI, 0.33-1.74; P = 0.64). CONCLUSIONS: Febrile infants 2 to 12 months of age with bronchiolitis have a clinically significant incidence of UTI, suggesting that UTI evaluation should be considered in these patients.

Teaching Infant Cardiopulmonary Resuscitation to Caregivers in the Emergency Department.

OBJECTIVES: Infant cardiopulmonary resuscitation (CPR) has been taught to caregivers of infants in inpatient settings. There are no studies to date that look at teaching infant CPR in the emergency department (ED). Using a framework of cognitive load theory, we compared teaching infant CPR to caregivers in a pediatric ED versus an inpatient setting. METHODS: Knowledge tests, 1-minute infant CPR performances on a Resusci Baby QCPR (Laerdal) manikin, and self-reported questionnaires were completed before and after caregivers were self-taught infant CPR using Infant CPR Anytime kits. The proportions of chest compression depth and rate that met quality standards from the American Heart Association's Basic Life Support program were measured. RESULTS: Seventy-four caregivers participated. Mean knowledge scores (out of a total score of 15) increased in both settings (ED preintervention: Mean (M) = 4.53 [SD = 1.97]; ED postintervention: M = 10.47 [SD = 2.90], P < 0.001; inpatient preintervention: M = 4.83 (SD = 2.08); inpatient postintervention: M = 10.61 [SD = 2.79], P < 0.001). Improvement in the proportion of chest compression that met high quality standards for depth increased in the inpatient group only. Neither groups had improvements in compression rates. There were no statistically significant differences in the difficulty of learning CPR, frequency of interruptions/distractions, or difficulty staying concentrated in learning CPR between the 2 settings. CONCLUSIONS: Caregivers in the ED and inpatient settings after a self-instructional infant CPR kit did not demonstrate adequate infant CPR performance. However, both groups gained infant CPR knowledge. Differences in cognitive loads between the 2 settings were not significant.

Leaving Without Being Seen From a Pediatric Emergency Department: Identifying Caregivers' Perspectives Using Q-methodology.

OBJECTIVE: National rates of left (or leaving) without being seen (LWBS) in pediatric emergency departments (PED) are higher than general emergency departments. We investigated coexisting perspectives on LWBS. METHODS: Q-methodology was implemented through a mixed-methods design. Semistructured interviews elicited a concourse of caregivers' thoughts on waiting in the PED and their consideration of LWBS. Themes from the concourse were identified and framed as statements. Caregivers sorted these statements, which ranged from choosing to stay versus leave the PED before their child is seen by a physician. Sorted data were analyzed through centroid factor analysis. RESULTS: Seventy-seven caregivers contributed interview data, from which 31 themes were identified and framed as statements. Thirty-one different caregivers contributed Q-sort data, from which 2 factors were revealed, each representing a unique perspective on LWBS. Most caregivers (26 of 31) shared the following perspective: "I would leave the PED before my child is seen by a doctor if there are no reassessments for my child while we are in the queue, no updates on our queue position, or no explanations for wait time." The remaining caregivers (5 of 31) perceived feelings of uncertainty and helplessness, lack of updates, and competing obligations as primary influences on LWBS. CONCLUSIONS: Elements that factor into caregivers' decision to LWBS from a PED include lack of reassessments, lack of updates on queue position, and lack of information about the triage process. Quality improvement interventions for decreasing LWBS rates should account for diverse coexisting perspectives such as these.

Surge activation by the emergency department for COVID-19.

In March 2020, the American College of Emergency Physicians (ACEP) published a national strategic plan for COVID-19, which provides general guidelines yet leaves logistical details for institutions to determine. Key capabilities from this plan provided a crucial foundation for a 16-day Emergency Department (ED) surge planning process at one pediatric institution. This paper describes critical milestones and lessons learned during this brief period, including derivation of criteria for ED surge activation, a full-scale surge drill, and the resultant ED surge protocol. The framework of real-time evaluation was used throughout the planning process and involved constant and iterative synthesis of real-time feedback from multidisciplinary stakeholders for responsive decision-making. Ultimately, the objective of this paper is to provide timely and readily actionable information to other institutions seeking guidance to apply the ACEP strategic plan for COVID-19.

Evaluating Changes in Diagnostic Accuracy of Ultrasound for Appendicitis: Does Practice Make Perfect?

BACKGROUND: Ultrasound (US) is the preferred method of initial evaluation for appendicitis in pediatrics. However, limited accuracy of US for appendicitis is an obstacle to implementation of US-first protocols at facilities less experienced with US. OBJECTIVES: The primary objective was to demonstrate changes in diagnostic accuracy of US for appendicitis over time, after implementation of an US-first protocol. Secondary objectives included evaluating trends in utilization and factors associated with accuracy of US. METHODS: We reviewed 5 years of pediatric emergency department encounters that included US evaluations for appendicitis. The primary outcome was conclusive US (fully visualized normal appendix or unequivocal appendicitis) vs. equivocal US (partially visualized or nonvisualized appendix). We also analyzed rates of conclusive US over time; accuracy, sensitivity, and specificity of US for appendicitis; and associations of US accuracy with patient gender, body mass index, and ultrasonographer's experience. RESULTS: A conclusive US report was found in 267 of 1058 encounters (25.2%); overall accuracy rate was 24.5%. Over 5 years, the diagnostic accuracy of US for appendicitis improved significantly from 13.9% to 31.5% (p = 0.001). Overall sensitivity was 80.7% and specificity was 77.6%. Male gender and dedicated US of the appendix were significantly associated with conclusive US (ps < 0.001). Higher body mass index was significantly associated with equivocal US (p < 0.001). Ultrasonographer experience was not significantly associated with conclusive US (p = 0.22). CONCLUSIONS: An US-first imaging protocol for appendicitis in children shows chronologic improvement in diagnostic accuracy. This may provide encouragement to facilities using computed tomography-based diagnostic protocols to implement US-first protocols to reduce childhood radiation exposure.

Reducing Abdominal Radiographs to Diagnose Constipation in the Pediatric Emergency Department.

OBJECTIVE: To determine the frequency of abdominal radiographs obtained in healthy children aged 6 months to 18 years to diagnose constipation in a pediatric emergency department, and evaluate the impact of quality improvement (QI) interventions on their use. STUDY DESIGN: QI study over 2.5 years at a large urban quaternary care children's hospital emergency department. Interventions consisted of educational presentations and individualized abdominal radiograph data reporting. The primary outcome measure was the percentage of abdominal radiographs performed on healthy patients discharged home with a diagnosis of constipation before and after QI interventions. RESULTS: The baseline total percentage of abdominal radiographs performed in otherwise healthy children discharged home with a diagnosis of constipation was 36% (October 2016 to January 2018). According to questionnaire results, ruling out obstruction was the most common reason for ordering an abdominal radiograph. After the QI interventions, the total percentage of abdominal radiograph decreased to 18% (April 2018 to March 2019). This 18% decrease was significant (P < .001) and sustained over a 12-month follow-up period. Throughout the study period, the average length of stay was 1.07 hours longer for children who had an abdominal radiograph. Clinically important return visits to the emergency department were uncommon during the postintervention phase (125/1830 [6.8%]), and not associated with whether or not an abdominal radiograph was performed at the initial visit. CONCLUSION: After these QI interventions, we noted a significant and sustained decrease in the percentage of abdominal radiographs obtained for otherwise healthy patients discharged home with a diagnosis of constipation.

Defining "Swarming" as a New Model to Optimize Efficiency and Education in an Academic Emergency Department.

BACKGROUND: Academic emergency medicine is a constant balance between efficiency and education. We developed a new model called swarming, where the bedside nurse, resident, and attending/fellow simultaneously evaluate the patient, including initial vital signs, bedside triage, focused history and physical examination, and discussion of the treatment plan, thus creating a shared mental model. OBJECTIVES: To combine perceptions from trainee physicians, supervising physicians, nurses, and families with in vivo measurements of emergency department swarms to better conceptualize the swarming model. METHODS: This mixed methods study was conducted using a convergent design. Qualitative data from focus groups with nurses, residents, and attendings/fellows were analyzed using directed content analysis. Swarming encounters were observed in real time; durations of key aspects and family satisfaction scores were analyzed using descriptive statistics. The qualitative and quantitative findings were integrated a posteriori. RESULTS: From the focus group data, 54 unique codes were identified, which were grouped together into five larger themes. From 39 swarms, mean (±SD) time (minutes) spent in patient rooms: nurses = 6.8 (±3.0), residents = 10.4 (±4.1), and attendings/fellows = 9.4 (±4.3). Electronic documentation was included in 67% of swarms, and 39% included orders initiated at the bedside. Mean (±SD) family satisfaction was 4.8 (±0.7; Likert scale 1-5). CONCLUSIONS: Swarming is currently implemented with significant variability but results in high provider and family satisfaction. There is also consensus among physicians that swarming improves trainee education in the emergency setting. The benefits and barriers to swarming are underscored by the unpredictable nature of the ED and the observed variability in implementation. Our findings provide a critical foundation for our efforts to refine, standardize, and appraise our swarming model.

Use of Audiobooks as an Environmental Distractor to Decrease State Anxiety in Children Waiting in the Pediatric Emergency Department: A Pilot and Feasibility Study.

Objectives: Anxiety and anticipatory stressors are commonly experienced by children visiting the Pediatric Emergency Department (PED), but little research exists that addresses the efficacy of interventions to decrease this stress. This one-sample pretest-postest pilot study gathered preliminary data on the feasibility and effectiveness of utilizing audiobooks to reduce fear and state anxiety in children in the PED. Methods: Participants were 131 children in kindergarten through 8th grade (M = 9.4 years, 54% female), triaged urgent or emergent, presenting to the PED. Participants self-reported fear (Children's Fear Scale) and state anxiety (modified State-Trait Anxiety Inventory for Children; mSTAIC) before and after listening to an age-appropriate audiobook (two options). Data regarding patient experience were also collected. Paired samples t-test was used to examine pre-post intervention changes in fear and state anxiety. Results: Significant, albeit small, improvements in fear and the mSTAIC states of nervous, calm, happy, and relaxed were found after use of the audiobook (Cohen's d z = 0.22-0.35). Small, yet significant correlations were found between child age/grade level and improvements in fear and in the mSTAIC states of scared and relaxed, suggesting that the audiobook was more beneficial for older participants. Over 60% of participants liked the audiobook content "a lot" as well as enjoyed listening to the audiobook "a lot." Without prompting, 15% of participants requested to listen to an additional audiobook. Conclusions: Listening to an audiobook is feasible and could be effective in decreasing fear and state anxiety for children during a waiting period in the PED. The technology is low-cost, simple, and portable. The results of this study should be interpreted with prudence due to the lack of a control group and results that, although significant, were modest based on effect size conventions; future studies should explore the impact of audiobooks on patient stress with an expanded sample size and control group.
