Abstract

Objective: Bruising can indicate abuse for infants. Bruise prevalence among infants in the Pediatric Emergency Department (PED) setting is unknown. Our objective was to determine prevalence of bruising, associated chief complaints (CC), and frequency of abuse evaluations in previously healthy infants presenting to PEDs. Methods: We conducted a prospective, observational, multi-center study of infants ≤12 months old presenting to PEDs. Structured sampling was utilized. Pediatric Emergency Medicine (PEM) clinicians performed complete skin examinations to screen for bruising. Study investigators documented skin findings, date of visit, patient's age, CC, and abuse evaluation. The primary outcome was prevalence of bruising. Secondary outcomes were prevalence of bruising based on CC and frequency of abuse evaluation. Point estimates of bruise prevalence and differences in bruise prevalence between patient subgroups were calculated with 95% confidence intervals (CI). Results: Bruising was identified in 88 of 2488 infants (3.5%, 95% CI: [2.9%, 4.4%]). Rates of bruising for infants ≤5 and >5 months old were 1.3% and 6.4%, respectively (difference 5.1%, 95% CI: [3.6%, 6.8%]). For infants ≤5 months old, 83% of bruising was associated with a trauma CC and only 0.2% of infants presenting with a medical CC had bruising. PEM clinicians obtained abuse evaluations on 23% of infants with bruising and that rate increased to 50% for infants ≤ 5 months of age. Conclusions: Bruising prevalence in children ≤ 12 months of age evaluated in PEDs was low, increased within age strata, and was most often associated with a trauma CC. Most bruised infants did not undergo an abuse evaluation. (Author Abstract)
