An epidemiologic study of traumatic head injuries in the emergency department of a tertiary health institution

Abstract

Introduction: Head injury (HI) is defined as physical damage to the brain or skull caused by external forces. The aim of this study was to examine the epidemiology of HI-related emergency department visits in our institution. Materials and Methods: This was a retrospective study of all patients with HI presenting at the accident and emergency department (AED) of the University of Port Harcourt Teaching Hospital from January 2013 to December 2014. The variables extracted for the study included patients’ age, gender, etiology, the severity of injury, the period of presentation, and the outcome of the management of HI by the AED. Results: HI occurred in 415 (30.9%) of the patients with trauma (1344) and 3.6% of all AED admissions (11,393). Of the patients with HI, 319 (76.9%) were males, and 96 (23.1%) were females. The male/female ratio was 3.3:1. The median age was 27 years (range − 1 month to 100 years). The highest frequency of 133 (32.0%) was in the age range of 21–30 years followed by 98 (23.6%) in the age range of 31–40 years. The most common etiologic factor was road traffic accident (RTA) [260 (62.6%)]. Most of the HIs were mild [162 (39.0%)]. More patients presented at night [161 (38.8%)]. There were 94 deaths, giving a case fatality rate of 22.6%. Conclusion: The 21–40 years age bracket was more affected by HI. RTA was the major cause of HI in our environment. The evening and night periods recorded the highest HI visits to the AED.
