title: Neurotrauma burden in a tropical urban conurbation level I trauma centre.
abstract: BACKGROUND
  Neurotrauma is a preventable public health problem whose quantum is said to be increasing in Third-World countries. This evaluation was performed to collate data which is needed to guide in designing, implementing, and evaluating public health prevention programmes with respect to neurotrauma.
  
  
  METHODS
  A single institution prospective study was carried out. Data was collected at the surgical emergency (SE) room over a year period (1st October 2012-30th September 2013). These included patients' demographics, cause of injury, region of the body involved, Glasgow coma scale score, and outcome. The patients were further divided into patients with traumatic brain (TBI) and spine injury (TSI). Analysis of the variables was by simple proportion, percentages, Chi-square and analysis of variance was used to determine the differences between group means. A probability (p) of less than 0.05 was considered statistically significant.
  
  
  RESULTS
  A total of 2149 neurotrauma cases (38.8%) out of a total of 5541 surgical trauma cases were seen within the study period at our SE unit. Of the neurotrauma cases, 1621 were males, giving a male:female ratio of 3.1:1. The mean age was 31 years (median 30 years). The most common age group was 20-29 (29.6%) and 30-39 years (29.6%). Assault was the cause of neurotrauma in 903 patients (42%), closely followed by road traffic injury in 744 patients (34.6%). Brain and spine injury separately occurred in 93.2% and 5.3% of cases, respectively. Five hundred patients (23.3%) were resuscitated and referred to other centres due to lack of bed space. Forty (1.9%) patients were dead on arrival, while twenty-six (1.2%) died while on treatment at the emergency room.
  
  
  CONCLUSIONS
  Neurotrauma is one of the most common form of trauma at our surgical emergency. Assault and road traffic injury (RTI) were the most common cause of TBI and TSI respectively, with RTI being the most common cause of moderate and severe TBI. The incidence and aetiology of TBI varies according to age and gender.
