ObjectiveThis study aimed to describe the epidemiology of headache in children attending a community mixed adult-pediatric emergency department (ED) in Australia with a view to providing scoping data for future headache-related projects for the pediatric ED research networks.MethodsThis is a retrospective cohort study by medical record review. Participants were children aged 2 to 16 years who presented to the ED between January 1, 2016, and December 31, 2016, with a major symptom of headache. Exclusion criteria were a history of recent head trauma, a ventriculoperitoneal shunt in situ, or known intracranial conditions associated with headache. Data collected included demographics, clinical features, investigations, diagnosis, disposition, and outcome. The primary outcomes of interest were the proportion of children with a serious ED diagnosis, the distribution of ED diagnoses, investigation ordering patterns, treatments provided, and clinical outcome.ResultsA total of 225 children were studied, with a median age of 9 years (interquartile range, 6-13 years). The most common associated symptoms were fever (47%) and vomiting (42%). The most common examination feature was fever (21%). Abnormal neurological findings were very uncommon. Few children underwent advanced neuroimaging (7 patients; 3%), and no intracranial abnormalities were detected. Seven children had a serious diagnosis (7/225 [3%]; 95% confidence interval, 2%-6%). Six of these 7 were viral meningitis, and there was 1 case of bacterial meningitis.ConclusionsIn a community teaching hospital cohort of children with headache, intercurrent viral illness is the most common cause. Serious causes were very uncommon. The rate of bacterial meningitis, tumor, or abscess was <1%. This has implications for the planning of research projects.Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
