RESUMO
BACKGROUND: Traumatic brain injury (TBI) can result in significant morbidity and mortality if not diagnosed in a timely manner. Brain computed tomography (CT) is the diagnostic gold standard but is of limited availability in most South African public hospitals, resulting in transfer of TBI patients to tertiary hospitals. OBJECTIVE: To describe the referral patterns and outcomes of patients with TBI referred to Groote Schuur Hospital Trauma Centre. METHODS: This was a retrospective audit of all patients admitted to the Trauma Centre who had a brain CT scan for suspected TBI between 1 February 2022 and 31 March 2022. Demographic data (age, sex), mechanism of injury and Glasgow Coma Score were recorded. Referral pathways were determined, and final disposition of patients was recorded. RESULTS: A total of 522 patients had a brain CT for TBI. Of these, 314 (60.1%) were referred from other hospitals. CT scan was abnormal in 178 (34.1%) patients. Three hundred and two (58.6%) were discharged home within 24 hours. The mean time between referral and CT scan was 13 hours. CONCLUSION: More than half of patients referred for a CT scan were discharged from the Trauma Centre within 24 hours of admission, which indicates additional costs and inefficiencies in the health system. These data are useful to guide resource planning and allocation for district hospitals, since less expensive point-of-care modalities now exist to diagnose TBI, and which are useful in indicating the prognosis of patients.

Background: South Africa has homicide rates six times the global average, predominantly among men, but little is known about male victims. As part of the country's first ever study of male homicide we compared 2017 male and female victim profiles for selected covariates, against global averages and previous estimates for 2009. Methods: We conducted a retrospective descriptive study of routine data collected through postmortem investigations, calculating age-standardised mortality rates for manner of death by age, sex and province and male-to-female incidence rate ratios with 95% confidence intervals. We then used generalised linear models and linear regression models to assess the association between sex and victim characteristics including age and mechanism of injury (guns, stabs and blunt force) within and between years. Findings: 87% of 19,477 homicides in 2017 were males, equating to seven male deaths for every female, with sharp force and firearm discharge the most common external causes. Rates were higher among males than females at all ages, and up to eight times higher among males aged 15-44 years. Provincial rates varied overall and by sex, with the highest comparative risk for men vs. women in the Western Cape Province (11.4 males for every 1 female). Male homicides peaked during December and were highest on weekends, underscoring the prominent role of alcohol as a risk factor. Significantly more males tested positive for alcohol than females. Interpretation: The massive, disproportionate and enduring homicide risk borne by adult South African men highlights the negligible prevention response. Only through challenging the normative perception of male invulnerability can we begin to address the enormous burden of violence impacting men. There is an urgent need to address the insidious effect of such societal norms alongside implementing structural interventions to overcome the root causes of poverty and inequality and better control alcohol and firearms.
