Pediatric mental health emergency department visits from 2017 to 2022: A multicenter study.

BACKGROUND: The COVID-19 pandemic adversely affected children's mental health (MH) and changed patterns of MH emergency department (ED) utilization. Our objective was to assess how pediatric MH ED visits during the COVID-19 pandemic differed from expected prepandemic trends. METHODS: We retrospectively studied MH ED visits by children 5 to <18 years old at nine U.S. hospitals participating in the Pediatric Emergency Care Applied Research Network Registry from 2017 to 2022. We described visit length by time period: prepandemic (January 2017-February 2020), early pandemic (March 2020-December 2020), midpandemic (2021), and late pandemic (2022). We estimated expected visit rates from prepandemic data using multivariable Poisson regression models. We calculated rate ratios (RRs) of observed to expected visits per 30 days during each pandemic time period, overall and by sociodemographic and clinical characteristics. RESULTS: We identified 175,979 pediatric MH ED visits. Visit length exceeded 12 h for 7.3% prepandemic, 8.4% early pandemic, 15.0% midpandemic, and 19.2% late pandemic visits. During the early pandemic, observed visits per 30 days decreased relative to expected rates (RR 0.80, 95% confidence interval [CI] 0.78-0.84), were similar to expected rates during the midpandemic (RR 1.01, 95% CI 0.96-1.07), and then decreased below expected rates during the late pandemic (RR 0.92, 95% CI 0.86-0.98). During the late pandemic, visit rates were higher than expected for females (RR 1.10, 95% CI 1.02-1.20) and for bipolar disorders (RR 1.83, 95% CI 1.38-2.75), schizophrenia spectrum disorders (RR 1.55, 95% CI 1.10-2.59), and substance-related and addictive disorders (RR 1.50, 95% CI 1.18-2.05). CONCLUSIONS: During the late pandemic, pediatric MH ED visits decreased below expected rates; however, visits by females and for specific conditions remained elevated, indicating a need for increased attention to these groups. Prolonged ED visit lengths may reflect inadequate availability of MH services.

Improving Identification of Firearm Access in Children With Mental Health Complaints.

OBJECTIVE: To determine if electronic medical record (EMR) changes and implementation of a study on firearm storage practices changed identification of firearm exposure in children presenting to a pediatric emergency department (PED) with mental health complaints. We also sought to determine the accuracy of information collected on firearm storage practices. METHODS: Retrospective study of EMR documentation of firearm exposure in PED patients with mental health complaints from January 20, 2015 until November 20, 2017. EMR changes occurred on January 20, 2016 and the firearms study began on February 13, 2016. The primary outcome was documentation of firearm exposure. Secondary outcomes were documentation of unsafe firearm storage practices. We also examined differences between clinical and research documentation of unsafe firearm storage practices post-intervention. We compared groups using descriptive statistics and chi-squared tests. We used statistical process control to examine the relationship between interventions and changes in outcomes. RESULTS: 5582 encounters were examined. Identification of firearm exposure increased from 11 to 17% postintervention. Identification of unsafe storage practices increased from 1.9% to 4.4% across all encounters. Special cause variation in both metrics occurred concurrently with the interventions. Postintervention, unsafe firearms storage practices in firearm owning families were under-identified (39% identified as not triple-safe in clinical data vs 75% in research data). CONCLUSIONS: EMR changes and implementation of a firearms study improved identification of firearm exposure and unsafe storage practices in families of PED patients being evaluated for mental health complaints. However, unsafe storage practices continued to be under-identified in firearm-owning families.

A multicenter evaluation of pediatric emergency department injury visits during the COVID-19 pandemic.

BACKGROUND: Injuries, the leading cause of death in children 1-17 years old, are often preventable. Injury patterns are impacted by changes in the child's environment, shifts in supervision, and caregiver stressors. The objective of this study was to evaluate the incidence and proportion of injuries, mechanisms, and severity seen in Pediatric Emergency Departments (PEDs) during the COVID-19 pandemic. METHODS: This multicenter, cross-sectional study from January 2019 through December 2020 examined visits to 40 PEDs for children < 18 years old. Injury was defined by at least one International Classification of Disease-10th revision (ICD-10) code for bodily injury (S00-T78). The main study outcomes were total and proportion of PED injury-related visits compared to all visits in March through December 2020 and to the same months in 2019. Weekly injury visits as a percentage of total PED visits were calculated for all weeks between January 2019 and December 2020. RESULTS: The study included 741,418 PED visits for injuries pre-COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020). Overall PED visits from all causes decreased 27.4% in March to December 2020 compared to the same time frame in 2019; however, the proportion of injury-related PED visits in 2020 increased by 37.7%. In 2020, injured children were younger (median age 6.31 years vs 7.31 in 2019), more commonly White (54% vs 50%, p < 0.001), non-Hispanic (72% vs 69%, p < 0.001) and had private insurance (35% vs 32%, p < 0.001). Injury hospitalizations increased 2.2% (p < 0.001) and deaths increased 0.03% (p < 0.001) in 2020 compared to 2019. Mean injury severity score increased (2.2 to 2.4, p < 0.001) between 2019 and 2020. Injuries declined for struck by/against (- 4.9%) and overexertion (- 1.2%) mechanisms. Injuries proportionally increased for pedal cycles (2.8%), cut/pierce (1.5%), motor vehicle occupant (0.9%), other transportation (0.6%), fire/burn (0.5%) and firearms (0.3%) compared to all injuries in 2020 versus 2019. CONCLUSIONS: The proportion of PED injury-related visits in March through December 2020 increased compared to the same months in 2019. Racial and payor differences were noted. Mechanisms of injury seen in the PED during 2020 changed compared to 2019, and this can inform injury prevention initiatives.

Behavioral Management of Children With Autism in the Emergency Department.

ABSTRACT: Autism spectrum disorder (ASD) is characterized by impaired social communication in conjunction with patterned behaviors. Often associated with emotional dysregulation, irritability, aggression, depression, and suicidality, ASD youth frequently present to the emergency department for behavioral and mental health evaluation. Psychiatric comorbidities, agitation, and depression are commonly encountered. During these visits, practitioners must thoughtfully consider organic etiologies for presenting symptoms, formulate plans to address risk of agitation, and understand how to effectively formulate disposition options in this patient population.

Racial and Ethnic Differences in Ondansetron Use for Acute Gastroenteritis in Children.

OBJECTIVES: There is limited research examining racial/ethnic disparities in antiemetic use for acute gastroenteritis (AGE). We assessed racial/ethnic differences in the care of children with AGE. METHODS: The Pediatric Health Information System was used to conduct a retrospective cohort study of children 6 months to 6 years old with AGE seen in participating emergency departments from 2016 to 2018. Cases were identified using International Classification of Diseases, Tenth Revision codes. The primary outcome was administration of ondansetron, secondary outcomes were administration of intravenous (IV) fluids and hospitalization, and primary predictor was race/ethnicity. Multivariable logistic regression followed by a mixed model adjusted for sex, age, insurance, and hospital to examine the association of race/ethnicity with each outcome. RESULTS: There were 78,019 encounters included; 24.8% of patients were non-Hispanic White (NHW), 29.0% non-Hispanic Black (NHB), 37.3% Hispanic, and 8.9% other non-Hispanic (NH) race/ethnicity. Compared with NHW patients, minority children were more likely to receive ondansetron (NHB: adjusted odds ratio, 1.36 [95% confidence interval, 1.2-1.55]; Hispanic: 1.26 [1.1-1.44]; other NH: 1.22 [1.07-1.4]). However, minority children were less likely to receive IV fluids (NHB: 0.38 [0.33-0.43]; Hispanic: 0.44 [0.36-0.53]; other NH: 0.51 [0.44-0.61]) or hospital admission (NHB: 0.37 [0.29-0.48]; Hispanic: 0.41 [0.33-0.5]; other NH: 0.52 [0.41-0.66]). Ondansetron use by hospital ranged from 73% to 95%. CONCLUSIONS: This large database analysis of emergency departments around the nation found that NHW patients were less likely to receive ondansetron but more likely to receive IV fluids and hospital admission than minority patients. These findings are likely multifactorial and may represent bias, social determinants of health, access to care, or illness severity among other possible causes.

Predictors of Invasive Herpes Simplex Virus Infection in Young Infants.

OBJECTIVES: To identify independent predictors of and derive a risk score for invasive herpes simplex virus (HSV) infection. METHODS: In this 23-center nested case-control study, we matched 149 infants with HSV to 1340 controls; all were ≤60 days old and had cerebrospinal fluid obtained within 24 hours of presentation or had HSV detected. The primary and secondary outcomes were invasive (disseminated or central nervous system) or any HSV infection, respectively. RESULTS: Of all infants included, 90 (60.4%) had invasive and 59 (39.6%) had skin, eyes, and mouth disease. Predictors independently associated with invasive HSV included younger age (adjusted odds ratio [aOR]: 9.1 [95% confidence interval (CI): 3.4-24.5] <14 and 6.4 [95% CI: 2.3 to 17.8] 14-28 days, respectively, compared with >28 days), prematurity (aOR: 2.3, 95% CI: 1.1 to 5.1), seizure at home (aOR: 6.1, 95% CI: 2.3 to 16.4), ill appearance (aOR: 4.2, 95% CI: 2.0 to 8.4), abnormal triage temperature (aOR: 2.9, 95% CI: 1.6 to 5.3), vesicular rash (aOR: 54.8, (95% CI: 16.6 to 180.9), thrombocytopenia (aOR: 4.4, 95% CI: 1.6 to 12.4), and cerebrospinal fluid pleocytosis (aOR: 3.5, 95% CI: 1.2 to 10.0). These variables were transformed to derive the HSV risk score (point range 0-17). Infants with invasive HSV had a higher median score (6, interquartile range: 4-8) than those without invasive HSV (3, interquartile range: 1.5-4), with an area under the curve for invasive HSV disease of 0.85 (95% CI: 0.80-0.91). When using a cut-point of ≥3, the HSV risk score had a sensitivity of 95.6% (95% CI: 84.9% to 99.5%), specificity of 40.1% (95% CI: 36.8% to 43.6%), and positive likelihood ratio 1.60 (95% CI: 1.5 to 1.7) and negative likelihood ratio 0.11 (95% CI: 0.03 to 0.43). CONCLUSIONS: A novel HSV risk score identified infants at extremely low risk for invasive HSV who may not require routine testing or empirical treatment.

Impact of a Firearm Safety Device Distribution Intervention on Storage Practices After an Emergent Mental Health Visit.

OBJECTIVE: To determine if providing firearm storage devices with training during clinical care improves safe storage practices in household members of children who present to a pediatric hospital with an emergent mental health complaint. METHODS: Prospective, pre-post study. Enrollment occurred in the emergency department or the inpatient psychiatric unit. Participants in the observation phase received usual care. Participants in the intervention phase were randomized to be offered a firearm storage device at either no or low ($5) cost and trained in its use. We surveyed participants at enrollment, 7, & 30 days post visit. Our primary outcome was triple-safe storage (TSS) - storing firearms unloaded, locked, and with ammunition stored and locked separately. RESULTS: About 256 participants enrolled. In the observation phase TSS increased from 21% (95% confidence interval [CI] 14%-30%) at baseline to 31% (95% CI 21%-42%) at 7 and 31% (95% CI 21%-43%) at 30 days. In the intervention phase, TSS increased from 32% (95% CI 25%-39%) at baseline to 56% (95% CI 48%-64%) at 7 and 56% (95% CI 47%-64%) at 30 days. Among those not practicing TSS at baseline, 7-day TSS was higher in the intervention (38%) versus the observation phase (14%, P = .001). CONCLUSIONS: Distribution and training in the use of firearm storage devices increased TSS in the study population, improves pediatric safety and should be part of the routine care of these high-risk patients.

Enhancing paediatric resuscitation team performance: targeted simulation-based team leader training.

Effective team leadership is linked to improved resuscitation outcomes. Previous studies have focused primarily on trainee performance and simulation-based outcomes. We hypothesised that a targeted simulation-based educational intervention for experienced physicians focusing on specific process and communication goals would result in improved performance during actual resuscitations. We conducted an observational pilot study evaluating specific process metrics during clinical resuscitations before and after a 1-hour training intervention for paediatric emergency medicine (PEM) supervising physicians using rapid cycle deliberate practice simulation-based training. Videos of clinical resuscitations from before and after the intervention were retrospectively reviewed to assess time to patient transfer to emergency department stretcher, time to primary assessment and time to team leader summary statement. Between March and July 2018, 21/38 of PEM supervising physicians participated in a training session. After the intervention period, clinical resuscitation teams showed significant improvements in targeted process metrics: transfer of patient within 1 min (79% vs 100%, p=0.03), assessment completed within 3 min (28% vs 75%, p=0.01) and summary statement within 5 min (50% to 85%, p=0.03). Brief, focused simulation-based team leader training can improve the teamwork and communication performance of experienced clinicians during clinical resuscitations.

Test Characteristics of Cerebrospinal Fluid Gram Stain to Identify Bacterial Meningitis in Infants Younger Than 60 Days.

ABSTRACT: In our cohort of 20,947 infants aged 60 days or younger, cerebrospinal fluid Gram stain had a sensitivity of 34.3% (95% confidence interval, 28.1%-41.1%) and a positive predictive value of 61.4% (95% confidence interval, 52.2%-69.8%) for positive cerebrospinal fluid culture, suggesting that Gram stain alone may lead to both underdiagnosis and overdiagnosis of bacterial meningitis.

Emergent Mental Health Visits to a Pediatric Hospital: Impact on Firearm Storage Practices.

OBJECTIVE: The aims of this study were to describe firearm storage practices in homes of patients evaluated for mental health (MH) complaints at a tertiary care children's hospital and to describe storage practice changes after treatment. METHODS: We surveyed families of children with MH complaints presenting to the emergency department or psychiatry unit who stored firearms in their homes between February 12, 2016, and January 14, 2017. Patients and families received standard care, including routine counseling on limiting access to methods of suicide. Participants completed surveys at baseline, 7, and 30 days after discharge. The primary outcome was triple safe firearm storage-storage of firearms unloaded, locked, and with ammunition stored and locked separately. RESULTS: Ninety-one household members of MH patients who stated they had firearms were enrolled at baseline. Seventy-seven (85%) completed at least 1 follow-up survey, and 63 (69%) completed both. At baseline, 21% (19/91) of participants reported engaging in triple safe firearm storage, 26% had an unlocked firearm, 23% had a loaded firearm, and 65% stored ammunition either unlocked or with their firearm. Triple safe storage rates increased to 31% at both 7 days and 30 days. Ten (17%) of 59 (P < 0.01) participants who did not report triple safe storage at baseline and completed a follow-up survey changed to reporting triple safe storage on follow-up. CONCLUSIONS: The majority of firearm-storing family members of children with MH complaints do not follow triple safe storage practices. Storage practices modestly improved after an emergent MH visit, but over two thirds of participants reported unsecured or partially secured firearms 7 and 30 days later.

Performance of the Modified Boston and Philadelphia Criteria for Invasive Bacterial Infections.

BACKGROUND: The ability of the decades-old Boston and Philadelphia criteria to accurately identify infants at low risk for serious bacterial infections has not been recently reevaluated. METHODS: We assembled a multicenter cohort of infants 29 to 60 days of age who had cerebrospinal fluid (CSF) and blood cultures obtained. We report the performance of the modified Boston criteria (peripheral white blood cell count [WBC] ≥20 000 cells per mm3, CSF WBC ≥10 cells per mm3, and urinalysis with >10 WBC per high-power field or positive urine dip result) and modified Philadelphia criteria (peripheral WBC ≥15 000 cells per mm3, CSF WBC ≥8 cells per mm3, positive CSF Gram-stain result, and urinalysis with >10 WBC per high-power field or positive urine dip result) for the identification of invasive bacterial infections (IBIs). We defined IBI as bacterial meningitis (growth of pathogenic bacteria from CSF culture) or bacteremia (growth from blood culture). RESULTS: We applied the modified Boston criteria to 8344 infants and the modified Philadelphia criteria to 8131 infants. The modified Boston criteria identified 133 of the 212 infants with IBI (sensitivity 62.7% [95% confidence interval (CI) 55.9% to 69.3%] and specificity 59.2% [95% CI 58.1% to 60.2%]), and the modified Philadelphia criteria identified 157 of the 219 infants with IBI (sensitivity 71.7% [95% CI 65.2% to 77.6%] and specificity 46.1% [95% CI 45.0% to 47.2%]). The modified Boston and Philadelphia criteria misclassified 17 of 53 (32.1%) and 13 of 56 (23.3%) infants with bacterial meningitis, respectively. CONCLUSIONS: The modified Boston and Philadelphia criteria misclassified a substantial number of infants 29 to 60 days old with IBI, including those with bacterial meningitis.

Procedural Training and Assessment for Pediatric Emergency Medicine Physicians Within the United States and Canada: A Survey Study.

OBJECTIVES: The aims of this study were to determine current practices in procedural training and skill assessment for attending physicians working in pediatric emergency departments within the United States and Canada and identify barriers to providing training and assessment. METHODS: This was a cross-sectional survey study. Members of the pediatric emergency medicine fellowship program directors and associate program directors Listserv were invited to participate in an anonymous survey about attending physician training and assessment practices for 9 specific procedures and barriers to training and assessment. RESULTS: Eighty-two (56.2%) of 146 recipients responded, with 79 surveys fully completed; 58.5% of responders report that their division offers procedural training, whereas 14.6% report assessment of procedural skills. The most common procedure for which participants report training and assessment is orotracheal intubation (53.1% and 7.5%, respectively), with training rates for other procedures ranging from 2.5% to 43.0%. Most sites that report training use simulation in some form for education. For assessment, simulation is used almost exclusively. Cost (50.6%), lack of faculty interest (36.7%), and lack of standardized guidelines (36.7%) are the most common barriers to training. Lack of standardized guidelines (51.9%), cost (43.0%), and lack of faculty interest (38.0%) are the most common barriers for assessment. CONCLUSIONS: Although pediatric emergency medicine physicians may be required to perform emergent procedures, opportunities to receive training and assessment in these procedures are limited. Simulation and other educational modalities are being used to provide skill training and assessment, but cost and lack of resources, standardized protocols, and faculty interest are barriers to the implementation of training and assessment programs.

Pediatric pain management in the emergency department.

Adequate analgesia is critical in the management of pediatric patients in the emergency department. Suboptimal treatment of pain can have deleterious effects in the short term, and it can also affect a patient's development and reaction to future painful experiences. Tools exist to quantify a patient's pain level regardless of age or developmental stage. Both pharmacologic and nonpharmacologic methods can be effective in the management of pediatric pain. Emergency clinicians must remain vigilant in the recognition, treatment, and reassessment of pediatric pain, as patients' developmental level may limit their ability to independently express their pain experience without prompting or tools. This issue reviews pain scales that are suitable for pediatric patients and discusses pediatric pain management using nonpharmacologic methods, topical, local, and regional anesthesia as well as systemic agents.

A Global Rating Scale and Checklist Instrument for Pediatric Laceration Repair.

Introduction: Laceration repair is a core procedural skill in which pediatric residents are expected to attain proficiency per the Accreditation Council for Graduate Medical Education. Restricted trainee work hours have decreased clinical opportunities for laceration repair, and simulation may be a modality to fill that clinical gap. There is a therefore a need for objective measures of pediatric resident competence in laceration repair. Methods: We created a global rating scale and checklist to assess laceration repair in the pediatric emergency department. We adapted the global rating scale from the Objective Structured Assessment of Technical Skills tool used to evaluate surgical residents' technical skills and adapted the checklist from a mastery training checklist related to infant lumbar puncture. We tested both tools in the pediatric emergency department. Eight supervising physicians used the tools to evaluate 30 residents' technical skills in laceration repair. We performed validation testing of both tools in the simulation environment. Based on formal evaluation, we developed a video to train future evaluators on the use of the global rating scale. Results: The global rating scale and checklist showed fair concordance across reviewers. Both tools received positive feedback from supervising physicians who used them. Discussion: We found that the global rating scale and checklist are more applicable to formative, rather than summative, training for resident laceration repair. We recommend using these educational tools with trainees in the simulation environment prior to trainees performing laceration repairs on actual patients.

Evaluation of a Modified Objective Structured Assessment of Technical Skills Tool for the Assessment of Pediatric Laceration Repair Performance.

Introduction The Accreditation Council for Graduate Medical Education (ACGME) has developed milestones including procedural skills under the core competency of patient care. Progress in training is expected to be monitored by residency programs. To our knowledge, there exists no tool to evaluate pediatric resident laceration repair performance. Methods The Objective Structured Assessment of Technical Skills was adapted to evaluate resident laceration repair performance using two components: a global rating scale (GRS) and a checklist. Pediatric and family medicine residents at a tertiary care children's hospital were filmed performing a simulated laceration repair. Videos were evaluated by at least five physicians trained in laceration repair. Concordance correlation coefficients (CCC) were calculated for the GRS and checklist scores. Scores for each resident were compared across levels of training and procedural experience. Spearman's rank order correlations were calculated to compare the checklist and GRS. Results Thirty residents were filmed performing laceration repair procedures. The CCC showed fair concordance across reviewers for the checklist (0.55, 95% CI: 0.38-0.69) and the GRS (0.53, 95% CI: 0.36-0.67). There was no significant difference in scores by self-reported experience or training level. There was correlation between the median GRS and checklist scores (Spearman ρ = 0.730, p < .001). Conclusions A novel tool to evaluate resident laceration repair performance in a pediatric emergency department showed fair agreement across reviewers. The study tool is not precise enough for summative evaluation; however, it can be used to distinguish between trainees who have and have not attained competence in laceration repair for formative feedback.

Pediatric Toxidrome Simulation Curriculum: Bupropion Overdose.

Introduction: Bupropion is a commonly used antidepressant, and overdose can lead to both neurologic and cardiovascular toxicity, including agitation, seizure, tachycardia, QT and QRS prolongation, and rhythm disturbances. Methods: We developed this simulation case for attendings, fellows, nurse practitioners, and nurses in the pediatric emergency department (ED). The scenario involved a 13-year-old male presenting to the ED with altered mental status and a generalized tonic-clonic seizure shortly after arrival. The team needed to quickly perform primary and secondary surveys, manage his airway and breathing, and initiate treatment for seizure. The team had to obtain an abbreviated history and include ingestion in the differential. The patient then developed pulseless ventricular tachycardia, and the team needed to respond with high-quality CPR, defibrillation, and advanced airway management. Preparatory materials, a debriefing guide, and scenario evaluation forms assisted with facilitation. Results: Twenty-eight physicians, 56 nurses, 10 nurse practitioners, four pharmacists, two students, and one respiratory therapist completed this simulation in 13 sessions. On a 5-point Likert scale, participants agreed with the stated objective of ability to manage a patient with a bupropion overdose (M = 4.09; range, 2-5). The scenario was rated as highly relevant (M = 4.93) and the debriefing as very effective (M = 4.85). Discussion: This scenario is a complete educational resource for setting up, implementing, and debriefing in an interprofessional setting. It was well received by learners from diverse professional backgrounds working together in actual care teams in the pediatric ED.

Application of the Bacterial Meningitis Score for Infants Aged 0 to 60 Days.

In 4292 infants aged ≤60 days with cerebrospinal fluid (CSF) pleocytosis, the bacterial meningitis score had excellent sensitivity (121 of 121 [100.0%] [95% confidence interval, 96.5%-100.0%]) but low specificity (66 of 4171 [1.6%] [95% confidence interval, 1.3%-2.0%]) and therefore should not be applied clinically to infants in this age group.

Lactic Acidosis in a Critically Ill Patient: Not Always Sepsis.

Lactic acidosis in the emergency department and other hospital settings is typically due to tissue hypoxia with sepsis being the most common cause. However, in patients with persistently elevated lactate without evidence of inadequate oxygen delivery, type B lactic acidosis should be considered. We report the case of a 12-year-old boy with relapsed and refractory pre-B-cell acute lymphoblastic leukemia who presented in distress with tachycardia, history of fever, and diffuse abdominal tenderness. The patient had severe metabolic acidosis with elevated lactate upon arrival to the emergency department. Despite aggressive fluid resuscitation and intravenous antibiotics, the patient's acidosis worsened. Serial blood cultures were negative, and he was eventually diagnosed with type B lactic acidosis secondary to relapsed acute lymphoblastic leukemia.

Herpes Simplex Virus Infection in Infants Undergoing Meningitis Evaluation.

BACKGROUND: Although neonatal herpes simplex virus (HSV) is a potentially devastating infection requiring prompt evaluation and treatment, large-scale assessments of the frequency in potentially infected infants have not been performed. METHODS: We performed a retrospective cross-sectional study of infants ≤60 days old who had cerebrospinal fluid culture testing performed in 1 of 23 participating North American emergency departments. HSV infection was defined by a positive HSV polymerase chain reaction or viral culture. The primary outcome was the proportion of encounters in which HSV infection was identified. Secondary outcomes included frequency of central nervous system (CNS) and disseminated HSV, and HSV testing and treatment patterns. RESULTS: Of 26 533 eligible encounters, 112 infants had HSV identified (0.42%, 95% confidence interval [CI]: 0.35%-0.51%). Of these, 90 (80.4%) occurred in weeks 1 to 4, 10 (8.9%) in weeks 5 to 6, and 12 (10.7%) in weeks 7 to 9. The median age of HSV-infected infants was 14 days (interquartile range: 9-24 days). HSV infection was more common in 0 to 28-day-old infants compared with 29- to 60-day-old infants (odds ratio 3.9; 95% CI: 2.4-6.2). Sixty-eight (0.26%, 95% CI: 0.21%-0.33%) had CNS or disseminated HSV. The proportion of infants tested for HSV (35%; range 14%-72%) and to whom acyclovir was administered (23%; range 4%-53%) varied widely across sites. CONCLUSIONS: An HSV infection was uncommon in young infants evaluated for CNS infection, particularly in the second month of life. Evidence-based approaches to the evaluation for HSV in young infants are needed.

Pediatric Simulation Cases for Primary Care Providers: Asthma, Anaphylaxis, Seizure in the Office.

Introduction: Although pediatric emergencies commonly occur in the outpatient setting, studies show that primary care providers often rely on hospitals or the emergency medical system to evaluate the distressed patient. This simulation-based curriculum addresses pediatric emergencies encountered by primary care providers. The cases were facilitated by faculty at an annual conference on urgent pediatric problems. Methods: Three cases are included in this curriculum: asthma, anaphylaxis, and seizure. Each features a brief narrative description of the case, learning objectives, instructor notes, an example of the ideal flow of the scenario, and anticipated management mistakes. Also provided are tools on optimizing the simulation environment, teamwork and communication, and the debrief. Educational materials are included in the respective medical pathologies. The simulations can be run using a high- or low-fidelity mannequin. Results: The simulations were carried out annually for 4 years with over 100 providers. Participants overall felt the curriculum was relevant to their practice in the realms of medical management and patient-provider communication. Discussion: These simulation cases train primary care providers to recognize a decompensating patient, activate the emergency response system, and initiate appropriate treatment for acutely ill pediatric patients with asthma, anaphylaxis, or seizure. The cases also reinforce teamwork and communication skills with the intention of improving overall readiness in the office. The simulations have been found to be effective learning tools at the University of Washington, which continues to train outpatient providers in emergency response annually using this curriculum.
