Tracking the Trauma Epidemic in KwaZulu-Natal, South Africa

Trauma remains an important cause of morbidity and mortality in South Africa, but attempts to track the epidemic are often based on mortality data, or derived from individual health facilities. This project is based on the routine collection of trauma data from all public health facilities in the province of KwaZulu-Natal (KZN), between 2012 and 2022.

Hospital level data on trauma over the past ten years was drawn from the district health information system (DHIS). Data relating to assaults, gunshots and motor vehicle collisions (MVCs) were recorded in the emergency rooms, whilst data on admissions are recorded in the wards and intensive care units.

There were 1,263,847 emergency room visits for assaults, gunshots and MVCs over the ten-year period and trauma admissions ranged between four and five percent of the total number of hospital admissions annually. There was a dramatic decrease in trauma presentations and admissions over 2020/2021 as a result of the COVID lockdowns. Over the entire period, intentional injury was roughly twice as frequent as non-intentional injury. Intentional trauma had an almost equal ratio of blunt assault to penetrating assault. Gunshot-related assault increased dramatically over the 2021/2022 collecting period.

The burden of trauma in KZN remains high. The unique feature of this burden is the excessively high rate of intentional trauma in the form of both blunt and penetrating mechanisms. Developing injury-prevention strategies to reduce the burden of interpersonal violence is more difficult than for unintentional trauma.
