Stratification of risk for emergent intracranial abnormalities in children with headaches: a Pediatric Emergency Care Applied Research Network (PECARN) study protocol

INTRODUCTION

Headache is a common chief complaint of children presenting to emergency departments (EDs). Approximately 0.5%-1% will have emergent intracranial abnormalities (EIAs) such as brain tumours or strokes. However, more than one-third undergo emergent neuroimaging in the ED, resulting in a large number of children unnecessarily exposed to radiation. The overuse of neuroimaging in children with headaches in the ED is driven by clinician concern for life-threatening EIAs and lack of clarity regarding which clinical characteristics accurately identify children with EIAs. The study objective is to derive and internally validate a stratification model that accurately identifies the risk of EIA in children with headaches based on clinically sensible and reliable variables.

METHODS AND ANALYSIS

Prospective cohort study of 28 000 children with headaches presenting to any of 18 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). We include children aged 2-17 years with a chief complaint of headache. We exclude children with a clear non-intracranial alternative diagnosis, fever, neuroimaging within previous year, neurological or developmental condition such that patient history or physical examination may be unreliable, Glasgow Coma Scale score<14, intoxication, known pregnancy, history of intracranial surgery, known structural abnormality of the brain, pre-existing condition predisposing to an intracranial abnormality or intracranial hypertension, head injury within 14 days or not speaking English or Spanish. Clinicians complete a standardised history and physical examination of all eligible patients. Primary outcome is the presence of an EIA as determined by neuroimaging or clinical follow-up. We will use binary recursive partitioning and multiple regression analyses to create and internally validate the risk stratification model.

ETHICS AND DISSEMINATION

Ethics approval was obtained for all participating sites from the University of Utah single Institutional Review Board. A waiver of informed consent was granted for collection of ED data. Verbal consent is obtained for follow-up contact. Results will be disseminated through international conferences, peer-reviewed publications, and open-access materials.

Increased severity of abusive head trauma during the first year of the COVID-19 pandemic

BACKGROUND

Abusive head trauma (AHT) is the leading cause of death from physical abuse in children. Reports regarding the impact of the COVID-19 pandemic on rates and severity of AHT are limited and with conflicting results.

OBJECTIVE

To determine the number and clinical characteristics of AHT cases presenting to a pediatric tertiary care center during the first year of the COVID-19 pandemic compared to the two prior years.

PARTICIPANTS AND SETTING

We performed a retrospective cohort study of patients <5 years old diagnosed with AHT at a single pediatric tertiary care center over a three-year period.

METHODS

Data were obtained for the pandemic year and two years before, including demographics, length of stay, physical and retinal examination findings, radiologic studies, electroencephalogram results, and mortality.

RESULTS

There were 27 cases of AHT during the first year of the pandemic and 55 during the two pre-pandemic years. Length of stay was similar for the two cohorts. The mortality rate was higher during the pandemic (29.6 % vs. 3.6 %; p < .01), as were the proportion of patients with retinal hemorrhages (84.6 % vs. 41.5 %; p < .01) and abnormal cervical spine imaging (52.6 % vs. 21.2 %; p = .02). There were no differences in age, sex, race, abnormalities on dermatological exam, skeletal surveys, and electroencephalograms.

CONCLUSIONS

We did not observe an increase in the number of patients with AHT during the pandemic but did see an increase in mortality, patients with retinal hemorrhages, and patients with abnormalities on cervical spine imaging. These data suggest a higher severity of AHT presenting to a pediatric tertiary care center during the pandemic.

Pediatric emergency medicine fellowship point-of-care ultrasound training in 2020

OBJECTIVES

The primary objective was to survey pediatric emergency medicine (PEM) leaders and fellows regarding point-of-care ultrasound (POCUS) training in PEM fellowship programs, including teaching methods, training requirements, and applications taught. Secondary objectives were to compare fellows' and program leaders' perceptions of fellow POCUS competency and training barriers.

METHODS

This was a cross-sectional survey of U.S. PEM fellows and fellowship program leaders of the 78 fellowship programs using two online group-specific surveys exploring five domains: program demographics; training strategies and requirements; perceived competency; barriers, strengths, and weaknesses of POCUS training; and POCUS satisfaction.

RESULTS

Eighty-three percent (65/78) of programs and 53% (298/558) of fellows responded. All participating PEM fellowship programs included POCUS training in their curriculum. Among the 65 programs, 97% of programs and 92% of programs utilized didactics and supervised scanning shifts as educational techniques, respectively. Sixty percent of programs integrated numerical benchmarks and 49% of programs incorporated real-time, hands-on demonstration as training requirements. Of the 19 POCUS applications deemed in the literature as core requirements for fellows, at least 75% of the 298 fellows reported training in 13 of those applications. Although less than half of fellows endorsed competency for identifying intussusception, ultrasound-guided pericardiocentesis, and transvaginal pregnancy evaluation, a higher proportion of leaders reported fellows as competent for these applications (40% vs. 68%, p ≤ 0.001; 21% vs. 39%, p = 0.003; and 21% vs. 43%, p ≤ 0.001). Forty-six percent of fellows endorsed a lack of PEM POCUS evidence as a training barrier compared to 31% of leaders (p = 0.02), and 39% of leaders endorsed a lack of local financial support as a training barrier compared to 23% of fellows (p = 0.01).

CONCLUSIONS

Although most PEM fellowship programs provide POCUS training, there is variation in content and requirements. Training does conform to many of the expert recommended guidelines; however, there are some discrepancies and perceived barriers to POCUS training remain.
