IntroductionAn environment in which traffic regulations are not strictly enforced often is characterized by carnage from motor vehicular crashes resulting in severe injuries with unacceptably high mortality. The descriptive demographics and injury characteristics of pedestrian road crash victims presenting to a tertiary medical center in southwestern Nigeria are presented in order to provide baseline epidemiology as a first step in determining areas of potential mitigation for care of unintentional injuries.MethodsConsecutive pedestrian road traffic crash patients treated in the Accident and Emergency Department of a tertiary hospital were prospectively reviewed from March 2007 to February 2008 to determine baseline demographics and clinical outcomes.ResultsA total of 184 patients with a mean value of the ages of 31.4 years were studied; 27% of the patients were <11 years of age. The male to female ratio was 1.6:1. Fifty-four percent of the victims were struck by automobiles and 29% were struck by motorcycles. Sixty-five percent were struck while crossing common thoroughfares. Head injury was sustained in 61% of patients. The mortality rate was 31.0% (n = 57). The clinical course leading to death showed 22.8% of the patients who died initially experienced hemorrhagic shock, 17.5% suffered a severe head injury, and 17.5% suffered aspiration. Autopsy confirmed brainstem herniation in 28.1% of the patients who died. The average interval between injury and death was 5.5 +/-13.6 days (range: 0-77 days). In this setting, three out of every ten patients experiencing pedestrian vehicular trauma will die before leaving the hospital. The elderly are most at risk, with two-thirds of victims dying from injuries sustained.ConclusionsThis raises serious questions about the prehospital- and hospital-based emergency services for vehicular road crash victims in this environment, and confirms the World Health Organization findings that Africa has the highest rate overall for unintentional injury deaths. A system-wide program must be put in place that addresses proven prevention measures across all sectors of the community.
