Abstract

Introduction: This study describes the demographics, aetiology, emergency centre diagnosis and severity indicators of patients with head injuries presenting to the largest referral hospital emergency centre in Botswana. Methods: Cross-sectional retrospective data was collected from July 2015 to September 2015 for all emergency centre head injury presentations at Princess Marina Hospital. Information was extracted from emergency centre records regarding patient demographics, mechanism of injury, clinical observations, diagnosis, and treatment. Results: Three-hundred and sixty head injury patients presented to the emergency centre in the three months, averaging four per day. 80% were less than 40 years of age and males accounted for 69% of all presentations. 58% of injuries were listed as being accidental, 39% recorded from assaults and 38% from road traffic accidents. The most common emergency centre clinical diagnosis was concussion and the most common radiological diagnosis skull fracture. The median Glasgow Coma Scale was 15 with a range from 3 to 15; and, among patients for whom Revised Trauma Score could be calculated, 79% scored the lowest probability of death in the Revised Trauma Score. Discussion: Head injury disproportionately overburdened males in this study, and head injury aetiology and demographic picture was similar to regional data. Severity scoring using the Glasgow Coma Scale was only available among 66% of patients and Revised Trauma Score calculable in half of presentations. Only 55% of head injury patients were discharged from the emergency centre, despite the preponderance of low severity scores. Head CTs appear to have been over-utilised and implementation of a Traumatic Head CT guideline for our setting is proposed. This study improves understanding of the burden of head injury in Botswana and advocates for national referral guidelines for patients with head injury in Botswana.
