Point-of-Care Ultrasound Educational Initiative for Insect Bites

This pre-post study, designed to decrease unnecessary antibiotic prescribing, will use a prospective cohort of patients presenting to the Pediatric Emergency Department (PED). Patients with local skin findings that the clinician believes are primarily due to an insect bite or sting will be approached for the study. The intervention will occur at the physician level. Midway through the study, physicians will receive an educational intervention describing how to differentiate cellulitis from allergic reaction using point-of-care bedside ultrasound. The main outcome observed will be whether or not the patient receives a prescription for antibiotics at the index visit.
