Epidemiology and injury severity of 294 extremity gunshot wounds in ten months: a report from the Cape Town trauma registry

Abstract

To describe the epidemiology and injury severity of patients with extremity gunshot injuries in an area with a high rate of interpersonal violence. Patients and methods: This is a prospective cohort study of patients who presented with an extremity gunshot injury and were recorded as part of a trauma registry at a large tertiary care hospital in Cape Town, South Africa, between June 2015 and April 2016. Patient demographics, injury severity scores, injury patterns and referral pathways were evaluated. Results: Of 1 123 gunshot trauma admissions in ten months, 290 (25.8%) patients (91.5% males, n=269) with a median age of 26 years (IQR 13.0) presented with extremity injuries. Median injury severity score (ISS) was 4.0 (IQR 8.0). Only one-fifth of patients had an ISS of 15 or more (n=50, 17%). Upper extremity injuries were associated with a higher risk of fractures (RR 2.15, p=0.05), higher number of nerve injuries (p=0.01), and a two times higher mean ISS (p=0.01). Admissions between 7pm and 7am with limited staffing at the emergency department were twice as high as the day admissions (n=169, 57.5% versus n=79, 26.9%).
