Consensus-Derived Recommended Skills for Transition to Residency Courses.

PURPOSE: Transition to residency (TTR) courses facilitate the medical student-residency transition and are an integral part of senior medical student training. The authors established a common set of skills for TTR courses, and an expected level of entrustment students should demonstrate in each skill on TTR course completion. METHOD: A modified Delphi approach was used with 3 survey iterations between 2020 and 2022 to establish skills to be included in a TTR course. Nine TTR experts suggested general candidate skills and conducted a literature search to ensure no vital skills were missed. A stakeholder panel was solicited from email lists of TTR educators, residency program directors, and residents at the panelists' institutions. Consensus was defined as more than 75% of participants selecting a positive inclusion response. An entrustment questionnaire asked panelists to assign a level of expected entrustment to each skill, with 1 indicating observation only and 6 indicating perform independently. RESULTS: The stakeholder panel initially consisted of 118 respondents with representation across educational contexts and clinical specialties. Response rates were 54% in iteration 2, 42% in iteration 3, and 33% on the entrustment questionnaire. After 3 iterations, 54 skills met consensus and were consolidated into 37 final skills categorized into 18 clinical skills (e.g., assessment and management of inpatient concerns), 14 communication skills (e.g., delivering serious news or having difficult conversations), 4 personal and professional skills (e.g., prioritization of clinical tasks), and 1 procedural skill (mask ventilation). Median entrustment levels were reported for all skills, with 19 skills having a level of expected entrustment of 4 (perform independently and have all findings double-checked). CONCLUSIONS: These consensus skills can serve as the foundation of a standardized national TTR curriculum framework. Entrustment guidance may help educational leaders optimize training and allocation of resources for TTR curriculum development and implementation.

Population Pharmacokinetics of Single Bolus Dose Fentanyl in Obese Children.

BACKGROUND: Childhood obesity is a significant problem. Obesity may alter the pharmacokinetics (PKs) of medications. Fentanyl is commonly used for procedural sedation, but there is a paucity of bolus dose fentanyl PK data in obese children. Better understanding of fentanyl PK in obese children would facilitate dosing recommendations. We conducted a study involving children with and without obesity to assess the potential differences in bolus dose fentanyl PK between the 2 groups. METHODS: We enrolled children 2 to 12 years of age with and without obesity, defined as >95th percentile body mass index (BMI) for age and sex, undergoing elective tonsillectomy ± adenoidectomy. After induction, subjects had 2 intravenous (IV) lines placed in 2 different extremities: 1 for medications and IV fluids and 1 for obtaining blood aliquots for fentanyl concentration analysis. After administration of 1 mcg/kg of fentanyl based on total body weight (TBW), blood sample collections for fentanyl concentration analysis were attempted at 5, 15, 30, 60, 90, and 120 minutes. Five-minute fentanyl concentrations were compared between obese and nonobese cohorts. Population PK analysis to examine the differences between obese and nonobese children was performed and included various body size descriptors, such as TBW, BMI, and fat-free mass (FFM), to examine their influence on model parameters. RESULTS: Half of the 30 subjects were obese. Mean fentanyl concentrations at 5 minutes were 0.53 ng/mL for the nonobese group and 0.88 ng/mL for the obese group, difference 0.35 ng/mL (95% CI, 0.08-0.61 ng/mL; P = .01). Population PK analysis showed that FFM was a significant covariate for the central volume of distribution. The potential clinical effect of an IV bolus dose of fentanyl based on TBW versus FFM in an obese child was assessed in a simulation using our model. 1 mcg/kg fentanyl dose based on TBW resulted in an approximately 60% higher peak fentanyl effect site concentration than dosing based on FFM. CONCLUSIONS: Our data demonstrated higher peak plasma fentanyl concentrations in obese compared to nonobese subjects. Population PK analysis found that FFM was a significant covariate for the central volume of distribution. Model simulation showed dosing of fentanyl in obese children based on TBW resulted in significantly higher peak concentrations than dosing based on FFM. Based on this modeling and the known concentration-effect relationship between fentanyl and adverse effects, our results suggest that bolus dosing of fentanyl in obese children should be based on FFM rather than TBW, particularly for procedures of short duration.

A descriptive study of screening and navigation on health-related social needs in a safety-net hospital emergency department.

BACKGROUND: Health-related social needs (HRSN) have been associated with worse clinical outcomes, increased Emergency Department (ED) utilization and higher healthcare costs. The ED is uniquely positioned to bring HRSN screening to the bedside and develop effective interventions. We evaluated whether navigation services for high-risk patients led to the resolution of HRSN. METHODS: Navigators screened a convenience sample of patients for HRSN with the Accountable Health Communities Screening Tool from October 2019 to January 2022. Patients with HRSN were considered high-risk if they had at least two ED visits in the previous 12 months. Patients who were high-risk were eligible for navigation including community referrals and one-on-one close follow-up. The HRSN status (resolved, in-progress, unable to resolve) was queried from the Centers for Medicare and Medicaid database. The state hospital association provided data on ED visits and inpatient hospitalizations within 6 months of the screening visit. RESULTS: Of 185,470 ED visits, HRSN screening occurred in 4050 (2%). HRSN were self-reported in 48% (1944) of patient visits, with 71% of these (1379) considered high-risk. 15% of high-risk patients with HRSN opted out of navigation. Food insecurity was the most identified HRSN (35%) followed by housing instability (26%), transportation needs (24%) and utility assistance (15%). Food insecurity was the most resolved HRSN (39%, in-progress 32%) followed by utility assistance (37%, in-progress 26%), transportation needs (35%, in-progress 35%) and housing instability (28%, in-progress 36%). High-risk visits in which the patient or guardian accepted navigation were less likely to be associated with an ED visit within 6 months of the screening visit (51%) compared to high-risk patients in which the patient or guardian opted out of navigation (61%, p < 0.001), but there was no difference in inpatient hospitalizations (p = 0.427). CONCLUSIONS: During the study period, one-third of HRSN were successfully resolved with another one-third in-progress. Navigation in high-risk patients was associated with fewer subsequent ED visits.

Decreasing Percentage of Infants With Very Low 5-Minute Apgar Scores at a Safety-Net Level III NICU.

OBJECTIVES: Low 5-minute Apgar scores predict mortality and may be associated with poor neurologic outcomes. Our percentage of infants with low 5-minute Apgar scores was higher than the national average (2.4%). Therefore, we aimed to decrease the percentage of infants with Apgar scores <4 at 5 minutes from a mean of 5.12% to <2.4% and decrease the percentage of infants receiving chest compressions (CCs) before intubation from 21% to <5%. METHODS: We completed 4 plan-do-study-act (PDSA) cycles from April 2015 through November 2018, including providing 24-hour advanced practice provider coverage (PDSA 1), initiating advanced practice provider-led delivery room scenarios for residents and education to secure the airway before CCs (PDSA 2), developing "Go Bags" with supplies (PDSA 3), and performing multidisciplinary mock codes (PDSA 4). We used a statistical process control p-chart to evaluate our primary outcome measure of the percentage of infants with 5-minute Apgar scores <4 from January 2012 through September 2021. RESULTS: The percent of infants with Apgar scores <4 at 5 minutes decreased from 5.12% in the baseline and intervention period to 2.16% in the sustainment period. We detected special cause with 8 points below the centerline. Infants born in the baseline period were 7.9 times more likely to receive CCs before intubation than in the intervention and sustainment periods (P = .002). CONCLUSIONS: We decreased the percentage of infants with 5-minute Apgar scores <4 and the percentage of infants receiving chest compressions before intubation. Ultimately, rigorous education and team collaboration through frequent multidisciplinary team mock codes were critical to our success.

Improving Management of Suspected Chlamydia and Gonorrhea in Adolescents with a Rapid Diagnostic Test.

We aimed to determined the impact of an intervention using rapid chlamydia (CT)/gonorrhea (GC) testing on reducing unnecessary antibiotic use, undertreatment of CT and/or GC, and length of stay (LOS) in an urban safety-net pediatric emergency department. Methods: Before 2020, we tested for CT/GC using a batched nucleic acid amplification test, with results available the following day. Starting in January 2020, we implemented rapid nucleic acid amplification test. Our primary outcome variables were undertreatment and overtreatment. We defined undertreatment as GC and/or CT-positive patients who did not receive appropriate treatment. We defined overtreatment as GC or CT-negative patients who received antibiotics. The balancing measure was the LOS. Results: There were 758 patients evaluated in the preimplementation period (2019), 612 in the implementation period (2020), and 626 in the postimplementation period (2021). Postimplementation, overtreatment decreased from 18.4% to 8.1%. Undertreatment did not differ by period but was less common among those tested with rapid versus standard testing (12.7% versus 9.9%, P = 0.05). Median LOS increased from 166 minutes (preimplementation) to 187 minutes (implementation) and 202 minutes (postimplementation; P < 0.001). Conclusions: Rapid CT/GC testing reduced unnecessary antibiotic use but increased LOS due to patients waiting for the test results before being discharged. Given the rapid increases in CT/GC rates and antimicrobial resistance, health systems should consider implementing rapid testing to appropriately direct antimicrobials to patients most likely to benefit.

Medication Errors in Pediatric Patients after Implementation of a Field Guide with Volume-Based Dosing.

BACKGROUND: Several studies have demonstrated the high frequency of medication errors in pediatric patients by prehospital providers during both patient care and simulation. In 2015, our hospital-based urban EMS system introduced the HandtevyTM Field Guide that provides precalculated pediatric doses in milliliters (mL) by patient age. We hypothesized that implementation of the Field Guide would increase the percentage of correct pediatric medication doses to greater than 85%. METHODS: We performed a single center retrospective cohort study of medications administered to patients < 13 years of age from August 2017 to July 2019 compared to 2014 baseline data through electronic medical record review. We excluded nebulized medications and online medication direction cases. Our primary outcome was the percentage of correct doses defined as a dose within 80-120% of the Field Guide dose recommendation. Each dosing error was reviewed by two investigators. RESULTS: We analyzed 483 drug administrations in 375 patients for the Field Guide study period. Doses were correct in 89.4% of medication administrations with 68.5% reportedly administered exactly as dictated by the Field Guide compared to 51.1% in the baseline period (p < 0.001). During the Field Guide study period, the following medications had 100% appropriate dosing: adenosine, dextrose 10%, diphenhydramine, epinephrine 1:10,000, glucagon, naloxone and oral ondansetron. Overdoses accounted for 4.4% of medication errors and underdoses accounted for 6.2% of medications errors. The most overdosed medications were intranasal (IN) midazolam (11.8%) and intravenous fentanyl (9.4%). The most underdosed medications were IN midazolam (23.5%) and intramuscular epinephrine 1:1000 (12.5%). The highest percentage of errors (20%) were seen in the zero to one-year-old age group. CONCLUSION: After implementation of a precalculated mL dose system by patient age for EMS providers, most pediatric medications were reportedly administered within the appropriate dose range. A field guide with precalculated doses (in mL) may be an effective tool for reducing pediatric medication dosing errors by EMS providers.

Evaluation of a Novel Point-of-Care Ultrasound Curriculum for First-Year Pediatric Residents.

OBJECTIVE: The aim of the study is to evaluate a novel point-of-care ultrasound (POCUS) educational curriculum for pediatric residents. METHODS: The cohort study in graduate medical education was completed from January 2017 to March 2019. Postgraduate year 1 (PGY1) pediatric residents attended the educational curriculum that consisted of 3 half-day sessions over a 3-month period. Each session consisted of a lecture (introduction, extended focused assessment with sonography for trauma, soft tissue/musculoskeletal, cardiac, and resuscitative applications) followed by supervised hands-on scanning sessions. Group ratio was 3 learners to 1 machine/expert instructor. Main outcome measures included pre- and post-written test scores, as well as objective structured clinical examination (OSCE) scores. RESULTS: Forty-nine PGY1 residents (78% women) completed the curriculum. The mean (SD) pretest score was 68% (8.5), and the mean posttest score was 83% (8.3) with a difference of 15 (95% confidence interval, 12.5-17.6; P < 0.001). Mean (SD) focused assessment with sonography for trauma OSCE score after the curriculum was 88.7% (11.9). The number of PGY1 pediatric residents that were comfortable performing POCUS examinations increased from pretraining to posttraining for soft tissue/musculoskeletal (14%-61%, P < 0.001), extended focused assessment with sonography for trauma (24%-90%, P < 0.001), and cardiac (18%-86%, P < 0.001). All participants found the curriculum useful, and 42 of 49 (86%) stated the curriculum increased their ability to acquire and interpret images. CONCLUSIONS: Postgraduate year 1 pediatric residents learned the basics of POCUS through 3 brief educational sessions. The increase in posttest scores demonstrated improved POCUS knowledge, and the high OSCE score demonstrated their ability to acquire ultrasound images. Point-of-care ultrasound guidelines are needed for pediatric residency programs.

Serious Bacterial Infections in Young Febrile Infants With Positive Urinalysis Results.

It is unknown whether febrile infants 29 to 60 days old with positive urinalysis results require routine lumbar punctures for evaluation of bacterial meningitis. OBJECTIVE: To determine the prevalence of bacteremia and/or bacterial meningitis in febrile infants ≤60 days of age with positive urinalysis (UA) results. METHODS: Secondary analysis of a prospective observational study of noncritical febrile infants ≤60 days between 2011 and 2019 conducted in the Pediatric Emergency Care Applied Research Network emergency departments. Participants had temperatures ≥38°C and were evaluated with blood cultures and had UAs available for analysis. We report the prevalence of bacteremia and bacterial meningitis in those with and without positive UA results. RESULTS: Among 7180 infants, 1090 (15.2%) had positive UA results. The risk of bacteremia was higher in those with positive versus negative UA results (63/1090 [5.8%] vs 69/6090 [1.1%], difference 4.7% [3.3% to 6.1%]). There was no difference in the prevalence of bacterial meningitis in infants ≤28 days of age with positive versus negative UA results (∼1% in both groups). However, among 697 infants aged 29 to 60 days with positive UA results, there were no cases of bacterial meningitis in comparison to 9 of 4153 with negative UA results (0.2%, difference -0.2% [-0.4% to -0.1%]). In addition, there were no cases of bacteremia and/or bacterial meningitis in the 148 infants ≤60 days of age with positive UA results who had the Pediatric Emergency Care Applied Research Network low-risk blood thresholds of absolute neutrophil count <4 × 103 cells/mm3 and procalcitonin <0.5 ng/mL. CONCLUSIONS: Among noncritical febrile infants ≤60 days of age with positive UA results, there were no cases of bacterial meningitis in those aged 29 to 60 days and no cases of bacteremia and/or bacterial meningitis in any low-risk infants based on low-risk blood thresholds in both months of life. These findings can guide lumbar puncture use and other clinical decision making.

BLOSSoM: Improving Human Milk Provision in Preterm Infants Through Texting Support.

Mother's own milk (MOM) reduces complications of preterm birth. Despite high initiation rates of expression, half of preterm infants do not receive MOM at discharge. Frequent outreach and a short message service (SMS) have improved MOM provision in term dyads. We aimed to improve MOM provision rate from 61% to >80% by implementing standardized lactation education and Breastfeeding & Lactation Outreach via SMS Supporting Mothers (BLOSSoM). Methods: The baseline period was June 2019 to April 2020. A multidisciplinary team implemented PDSA cycles: education/documentation (standardized lactation education and education documentation, May 2020-April 2021), and BLOSSoM (SMS program providing educational texts/videos, reminders, 2-way communication with neonatal intensive care unit (NICU) lactation, May 2021-December 2021). The primary outcome was MOM provision at NICU discharge/transfer for infants younger than 34 weeks, as analyzed on the SPC chart. BLOSSoM participants evaluated the program using a 5-point Likert scale. Results: Demographic and clinical characteristics were unchanged among the three periods. However, the monthly MOM provision rate improved from 61% to 81%. Eighty-seven percent of BLOSSoM participants completed the evaluation with 83% rating the program most supportive, 78% rating the videos as the most helpful, followed by team check-ins (54%) and 2-way texting (24%). Conclusions: Using a multidisciplinary approach, we improved the monthly MOM provision rate at discharge/transfer for preterm infants. SMS providing educational texts/media and 2-way communication supporting lactating NICU mothers was critical to our success. Providing another method of communication through SMS was well accepted and valued by the majority.

Point-of-Care Ultrasound Use by EMS Providers in Out-of-Hospital Cardiac Arrest.

AIM: Paramedics received training in point-of-care ultrasound (POCUS) to assess for cardiac contractility during management of medical out-of-hospital cardiac arrest (OHCA). The primary outcome was the percentage of adequate POCUS video acquisition and accurate video interpretation during OHCA resuscitations. Secondary outcomes included POCUS impact on patient management and resuscitation protocol adherence. METHODS: A prospective, observational cohort study of paramedics was performed following a four-hour training session, which included a didactic lecture and hands-on POCUS instruction. The Prehospital Echocardiogram in Cardiac Arrest (PECA) protocol was developed and integrated into the resuscitation algorithm for medical non-shockable OHCA. The ultrasound (US) images were reviewed by a single POCUS expert investigator to determine the adequacy of the POCUS video acquisition and accuracy of the video interpretation. Change in patient management and resuscitation protocol adherence data, including end-tidal carbon dioxide (EtCO2) monitoring following advanced airway placement, adrenaline administration, and compression pauses under ten seconds, were queried from the prehospital electronic health record (EHR). RESULTS: Captured images were deemed adequate in 42/49 (85.7%) scans and paramedic interpretation of sonography was accurate in 43/49 (87.7%) scans. The POCUS results altered patient management in 14/49 (28.6%) cases. Paramedics adhered to EtCO2 monitoring in 36/36 (100.0%) patients with an advanced airway, adrenaline administration for 38/38 (100.0%) patients, and compression pauses under ten seconds for 36/38 (94.7%) patients. CONCLUSION: Paramedics were able to accurately obtain and interpret cardiac POCUS videos during medical OHCA while adhering to a resuscitation protocol. These findings suggest that POCUS can be effectively integrated into paramedic protocols for medical OHCA.

Evaluation of an Integrated Psychology Service in a Pediatric Emergency Department and Urgent Care.

OBJECTIVES: Children visiting emergency departments (EDs) are disproportionately affected by mental health disorders. Integrated behavioral health models hold promise for improving care among ED patients. We implemented and evaluated a novel behavioral health service integrated psychology trainees in a safety net hospital's pediatric ED and urgent care. METHODS: Consultations and interventions provided were identified from the service's patient registry. Patients treated by the service were matched based on age, sex, day, and month of presentation to control patients who received a brief assessment by a specialized psychiatric nurse or patients receiving comprehensive management in a psychiatric emergency service. Rates of ED return visits were obtained from local hospital records, and insurance claims were used to identify rates of psychiatric hospitalization and outpatient follow-up care. RESULTS: The most commonly provided interventions among 71 intervention patients were assistance with connection to follow-up behavioral health treatment (65%), relaxation training (41%), and motivational interviewing (31%). These patients were matched with 142 comparison patients. There was no difference among groups in return rates within 90 days among intervention versus nurse assessment or psychiatric emergency service patients (25% vs 23% vs 13%, P = 0.14). Insurance claims data were available for 115 patients (54%): within 90 days, integrated care patients were less likely to have at least 1 outpatient claim (52% vs 78% vs 84%, P < 0.01), and there was no difference in rates of psychiatric hospital admission (18% vs 20% vs 24%, P = 0.83). CONCLUSIONS: Although this psychology-led integrated behavioral health service delivered a range of brief psychotherapeutic interventions, its impact on outpatient, inpatient, and emergency care was mixed. This lower follow-up rate among intervention patients may reflect the success of active psychological treatment in the ED, lower acuity among intervention patients, or implications of the study's safety net setting. The authors discuss this model's potential for enhancing mental health care in pediatric EDs.

Screening for health-related social needs in the emergency department: Adaptability and fidelity during the COVID-19 pandemic.

BACKGROUND AND OBJECTIVES: We sought to evaluate a screening and referral program for health-related social needs (HRSN) in our ED. Our goals were to (1) quantify successful screenings prior to and during the initial peak of the pandemic, and (2) describe the HRSNs identified. METHODS: We performed an observational analysis of ED-based screening for HRSN in Medicare and Medicaid patients at our large urban safety-net hospital. Screening was performed by patient navigators utilizing the ten question, validated Accountable Health Communities (AHC) Screening Tool, which screens for food insecurity, housing instability, transportation needs and utility assistance and interpersonal safety. Patients who screened positive for HRSN were provided with handouts listing community resources. For patients with two or more self-reported ED visits in the last 12 months and any identified HRSN, ongoing navigation after discharge was provided utilizing community resource referrals. During the pre-pandemic period from November 1, 2019 - January 31, 2020, screening occurred in-person. Screening during the pandemic from March 1, 2020 - May 31, 2020 occurred remotely via telephone. Descriptive statistics including frequency rates and percentages were calculated. Successful screening was defined as completing the screening survey with a navigator and being triaged to either no assistance, resource handouts, or navigation services. RESULTS: Among the adult and pediatric patients screened for HRSN, 158 (16%) qualified for community resource handouts and 440 (44.4%) qualified for patient navigator services. The proportion of patients receiving both resources and care navigation remained similar in the pre- and post-periods of the study, at 227 (45%) and 213 (43.9%) respectively. However, the proportion of ED patients with a HRSN need doubled from 56 (11.1%) in the pre-period to 102 (21%) in the post-period. Food insecurity was the most identified HRSN in both the pre-pandemic period (27.3%) and during the pandemic (35.8%). CONCLUSION: We found that remote HRSN screening for ED patients during the COVID-19 pandemic resulted in similar proportions of successfully completed screenings compared to pre-pandemic efforts. This demonstrates the feasibility of utilizing alternative methods of screening and referral to community resources from the ED, which could facilitate this type of intervention in other EDs. During the pandemic HRSN increased, likely reflecting the economic impact of the pandemic.

Improving timeliness of hepatitis B vaccine administration in an urban safety net level III NICU.

OBJECTIVE: To avoid preventable consequences of perinatal hepatitis B infection, all infants should be given hepatitis B vaccine (HBV) within 24 hours of birth if birth weight is ≥2 kg and at 30 days of life or at discharge if <2 kg, to provide highest seroprotection rates while ensuring universal vaccination prior to discharge. We aimed to achieve timely HBV administration in >80% of eligible infants in both birthweight groups and decrease infants discharged home without receiving HBV to <1% over an 18-month period and sustain results for an additional 15 months. METHODS: Data were collected from June 2016 to May 2020 in a level III neonatal intensive care unit. A multidisciplinary team identified barriers and interventions through Plan-Do-Study-Act cycles from September 2017 to February 2019: using pharmacists as champions, overcoming legal barriers, staff education and best practice alerts (BPAs) embedded in electronic health records. Statistical process control (SPC) p charts were used to evaluate the primary outcome measure, monthly percentage of infants receiving timely HBV administration stratified by birthweight categories (≥2 and <2 kg). For infants receiving HBV outside the time frame, absolute difference of timeliness was calculated. RESULTS: Mean timely HBV administration improved from 45% to 95% (≥2 kg) and from 45% to 85% (<2 kg) with special cause variation in SPC charts. Infants discharged without receiving HBV decreased from 4.6% to 0.22%. Of those given HBV outside the recommended time frame, median absolute time between recommended and actual administration time decreased significantly: from 3.5 days (IQR 1.6, 8.6) to 0.3 day (IQR 0.1, 0.8) (p<0.001) in ≥2 kg group and from 6 days (IQR 1, 15) to 1 day (IQR 1, 6.5) (p=0.009) in <2 kg group. CONCLUSIONS: Using a multidisciplinary approach, we significantly improved and sustained timely HBV administration and nearly eliminated infants discharged home without receiving HBV. Pharmacists as champions and BPAs were critical to our success.

Randomized Controlled Trial of Point-of-Care Ultrasound Education for the Recognition of Tension Pneumothorax by Paramedics in Prehospital Simulation.

OBJECTIVE: The primary goal of this study was to determine if ultrasound (US) use after brief point-of-care ultrasound (POCUS) training on cardiac and lung exams would result in more paramedics correctly identifying a tension pneumothorax (TPTX) during a simulation scenario. METHODS: A randomized controlled, simulation-based trial of POCUS lung exam education investigating the ability of paramedics to correctly diagnose TPTX was performed. The US intervention group received a 30-minute cardiac and lung POCUS lecture followed by hands-on US training. The control group did not receive any POCUS training. Both groups participated in two scenarios: right unilateral TPTX and undifferentiated shock (no TPTX). In both scenarios, the patient continued to be hypoxemic after verified intubation with pulse oximetry of 86%-88% and hypotensive with a blood pressure of 70/50. Sirens were played at 65 decibels to mimic prehospital transport conditions. A simulation educator stated aloud the time diagnoses were made and procedures performed, which were recorded by the study investigator. Paramedics completed a pre-survey and post-survey. RESULTS: Thirty paramedics were randomized to the control group; 30 paramedics were randomized to the US intervention group. Most paramedics had not received prior US training, had not previously performed a POCUS exam, and were uncomfortable with POCUS. Point-of-care US use was significantly higher in the US intervention group for both simulation cases (P <.001). A higher percentage of paramedics in the US intervention group arrived at the correct diagnosis (77%) for the TPTX case as compared to the control group (57%), although this difference was not significantly different (P = 0.1). There was no difference in the correct diagnosis between the control and US intervention groups for the undifferentiated shock case. On the post-survey, more paramedics in the US intervention group were comfortable with POCUS for evaluation of the lung and comfortable decompressing TPTX using POCUS (P <.001). Paramedics reported POCUS was within their scope of practice. CONCLUSIONS: Despite being novice POCUS users, the paramedics were more likely to correctly diagnose TPTX during simulation after a brief POCUS educational intervention. However, this difference was not statistically significant. Paramedics were comfortable using POCUS and felt its use improved their TPTX diagnostic skills.

Time to Positive Blood and Cerebrospinal Fluid Cultures in Febrile Infants ≤60 Days of Age.

OBJECTIVES: To determine the time to positivity for bacterial pathogens and contaminants in blood and cerebrospinal fluid (CSF) cultures in a cohort of febrile infants ≤60 days of age. METHODS: This was a secondary analysis of prospective observational multicenter study of noncritically ill infants ≤60 days of age with temperatures ≥38°C and blood cultures (December 2008 to May 2013). The main outcome was time to positivity for bacterial pathogens and contaminants. RESULTS: A total of 256 of 303 (84.49%) patients with positive blood cultures, and 73 of 88 (82.95%) with positive CSF cultures met inclusion criteria. Median time (interquartile range [IQR]) to positivity for blood cultures was 16.6 hours (IQR 12.6-21.9) for bacterial pathogens (n = 74) and 25.1 hours (IQR 19.8-33.0) for contaminants (n = 182); P < .001. Time to bacterial pathogen positivity was similar in infants 0 to 28 days of age (15.8 hours [IQR 12.6-21.0]) and 29 to 60 days of age (17.2 [IQR 12.9-24.3]; P = .328). Median time to positivity for CSF was 14.0 hours (IQR 1.5-21.0) for bacterial pathogens (n = 22) and 40.5 hours (IQR 21.2-62.6) for contaminants (n = 51); P < .001. A total of 82.4% (95% confidence interval, 71.8-90.3) and 81.8% (95% confidence interval, 59.7%-94.8%) of blood and CSF cultures showed bacterial pathogen positivity within 24 hours. CONCLUSIONS: Among febrile infants ≤60 days of age, time to blood and CSF positivity was significantly shorter for bacterial pathogens than contaminants. Most blood and CSF cultures for bacterial pathogens were positive within 24 hours. With our findings, there is potential to reduce duration of hospitalization and avoid unnecessary antibiotics.

Critically Ill Pediatric Case Exposure During Emergency Medicine Residency.

BACKGROUND: Eighty-eight percent of pediatric emergency department (ED) visits occur in general EDs. Exposure to critically ill children during emergency medicine (EM) training has not been well described. OBJECTIVE: The objective was to characterize the critically ill pediatric EM case exposure among EM residents. METHODS: This is a secondary analysis of a multicenter retrospective review of pediatric patients (aged < 18 years) seen by the 2015 graduating resident physicians at four U.S. EM training programs. The per-resident exposure to Emergency Severity Index (ESI) Level 1 pediatric patients was measured. Resident-level counts of pediatric patients were measured; specific counts were classified by age and Pediatric Emergency Care Applied Network diagnostic categories. RESULTS: There were 31,552 children seen by 51 residents across all programs; 434 children (1.3%) had an ESI of 1. The median patient age was 8 years (interquartile range [IQR] 3-12 years). The median overall pediatric critical case exposure per resident was 6 (IQR 3-12 cases). The median trauma and medical exposure was 2 (IQR 0-3) and 3 (IQR 2-10), respectively. For 13 out of 20 diagnostic categories, at least 50% of residents did not see any critical care case in that category. Sixty-eight percent of residents saw 10 or fewer critically ill cases by the end of training. CONCLUSION: Pediatric critical care exposure during EM training is very limited. These findings underscore the importance of monitoring trainees' case experience to inform program-specific curricula and to develop strategies to increase exposure and resident entrustment, as well as further research in this area.

Application of Frequent, Spaced Multiple-choice Questions as an Educational Tool in the Pediatric Emergency Department.

OBJECTIVES: The objective was to assess the feasibility of using spaced multiple-choice questions (MCQs) to teach residents during their pediatric emergency department (PED) rotation and determine whether this teaching improves knowledge retention about pediatric rashes. METHODS: Residents rotating in the PED from four sites were randomized to four groups: pretest and intervention, pretest and no intervention, no pretest and intervention, and no pretest and no intervention. Residents in intervention groups were automatically e-mailed quizlets with two MCQs every other day over 4 weeks (20 questions total) via an automated e-mail service with answers e-mailed 2 days later. Retention of knowledge was assessed 70 days after enrollment with a posttest of 20 unique, content-matched questions. RESULTS: Between August 2015 and November 2016, a total 234 residents were enrolled. The completion rate of individual quizlets ranged from 93% on the first and 76% on the 10th quizlet. Sixty-six residents (55%) completed all 10 quizlets. One-hundred seventy-three residents (74%) completed the posttest. There was no difference in posttest scores between residents who received a pretest (61.0% ± 14.5%) and those who did not (64.6% ± 14.0%; mean difference = -3.7, 95% confidence interval [CI] = -8.0 to 0. 6) nor between residents who received the intervention (64.5% ± 13.3%) and those who did not receive the intervention (61.2% ± 15.2%; mean difference = 3.2, 95% CI = -1.1 to 7.5). For those who received a pretest, scores improved from the pretest to the posttest (46.4% vs. 60.1%, respectively; 95% CI = 9.7 to 19.5). CONCLUSION: Providing spaced MCQs every other day to residents rotating through the PED is a feasible teaching tool with a high participation rate. There was no difference in posttest scores regardless of pretest or intervention. Repeated exposure to the same MCQs and an increase in the number of questions sent to residents may increase the impact of this educational strategy.

Educational Benefits of Allowing Pediatrician Supervision of Emergency Medicine Residents.

BACKGROUND: According to the Accreditation Council for Graduate Medical Education emergency medicine (EM) program requirements, EM residents on EM rotations must be supervised by board-certified/board-prepared EM or pediatric EM (PEM) faculty. OBJECTIVE: We sought to understand the effect of allowing EM residents to be supervised by attending pediatricians while caring for pediatric urgent care patients. METHODS: The EM residents were permitted to staff pediatric urgent care patients with either an EM/PEM attending or an attending pediatrician from August 2017 to July 2018. Outcomes were assessed through resident focus groups, a mixed-methods survey of EM residents and EM/PEM/pediatrician attendings, and clinical outcomes, including length of stay, best evidence/clinical care guideline adherence, and 48-hour return visits requiring admission. Qualitative data were inductively coded using a phenomenological framework, with themes emerging from consensus discussion. RESULTS: Ninety percent of residents participated in 1 of 7 focus groups. Four key themes emerged from qualitative analysis of focus group transcripts: (1) pediatricians have unique skills that complement those of EM physicians; (2) EM resident education improved; (3) patients may get better care with dual staffing; and (4) other PEM department and urgent care team members may have benefited from the change. The survey response rate was 72%, and it did not uncover additional themes. Length of stay was shorter for patients supervised by attending pediatricians (114 versus 128 minutes, P < .001); there was no difference in best evidence/clinical care guideline adherence or 48-hour return visits requiring admission. CONCLUSIONS: Physicians' perceived education was improved by adding complementary perspectives without significant negative consequences for learners or patients.

A Novel Approach to Neonatal Resuscitation Education for Senior Emergency Medicine Residents.

The majority of pediatric visits occur in general emergency departments. Caring for critically ill neonates is a low-frequency but high-stakes event for emergency physicians, which requires specialized knowledge and hands-on training. We describe a novel clinical rotation for emergency medicine (EM) residents that specifically augments skills in neonatal resuscitation through direct participation as a member of the neonatal resuscitation team. The neonatal resuscitation rotation evaluation median score of 4 (interquartile range [IQR] 3,4) was higher compared to all other off-service senior resident rotations combined (median 3, IQR 3,4) for the academic year 2018-2019. Ninety-two percent of residents evaluated the curriculum change as beneficial (median 4, IQR 4,4). The neonatal resuscitation rotation was rated more favorably than the pediatric intensive care rotation (median 4 IQR 3,4 vs median 3, IQR 2, 3) at a tertiary care children's hospital during the third year. Residency programs may want to consider implementing a directed neonatal resuscitation experience as part of a comprehensive pediatric curriculum for EM residents.
