Vital Statistics: Estimating Injury Mortality in Kigali, Rwanda

Abstract

Background: Globally, injury deaths largely occur in low- and middle-income countries. No estimates of injury associated mortality exist in Rwanda. This study aimed to describe the patterns of injury-related deaths in Kigali, Rwanda using existing data sources.

Methods: We created a database of all deaths reported by the main institutions providing emergency care in Kigali—four major hospitals, two divisions of the Rwanda National Police, and the National Emergency Medical Service--during 12 months (Jan–Dec 2012) and analyzed it for demographics, diagnoses, mechanism and type of injury, causes of death, and all-cause and cause-specific mortality rates.

Results: There were 2682 deaths, 57% in men, 67% in adults >18 year, and 16% in children <5 year. All-cause mortality rate was 236/100,000; 35% (927) were due to probable surgical causes. Injury-related deaths occurred in 22% (593/2682). The most common injury mechanism was road traffic crash (cause-specific mortality rate of 20/100,000). Nearly half of all injury deaths occurred in the prehospital setting (47%, n = 276) and 49% of injury deaths at the university hospital occurred within 24 h of arrival. Being injured increased the odds of dying in the prehospital setting by 2.7 times (p < 0.0001).

Conclusions: Injuries account for 22% of deaths in Kigali with road traffic crashes being the most common cause.Injury deaths occurred largely in the prehospital setting and within the first 24 h of hospital arrival suggesting the need for investment in emergency infrastructure. Accurate documentation of the cause of death would help policy makers make data-driven resource allocation decisions.
