Epidemiological characteristics and comparative outcome of blast versus gunshot injuries of the extremities in Somalia

BACKGROUND: War conflicts and terror-related injuries constitute a significant public health problem in Somalia. We aim to characterize and compare the injury characteristics of gunshot and blast injuries of the extremities. METHODS: The data of 333 patients with gunshot and blast injuries of the extremities over three years were retrospectively reviewed. The demographics, injury characteristics, and outcomes were analyzed. RESULTS: Most of the patients had injuries due to gunshot casualties compared with blast victims (n = 222, 66.7% vs. n = 111, 33.3%). Patients with gunshot wounds (GSW) had a more significant proportion of males than those with blast wounds (BW) (95.5% vs. 85.6%, P < 0.001). There were more open extremity fractures in GSW casualties (96.4% vs. 81.1%). The BW victims had significantly higher associated injuries (52.3% vs. 18.5%, P < 0.001). The BW group had a higher injury severity score (ISS ≥ 16 in 55%, P < 0.001). The need for an intensive care unit (ICU) admission was significantly higher in the BW patients (18% vs. 6.3%, P < 0.001); as well as the length of hospital stay (LOS) was higher in the BW group compared with the GW patients (> 2-week hospital stay in 31% vs. 19%, P < 0.04). About a 2.7% mortality rate was observed in BW (P < 0.014). CONCLUSION: Gunshot and explosion injuries comprise the majority of war and terror-related trauma of the extremities. These injury mechanisms differ in the body regions involved, the severity of the injury, duration of hospital stay, need for ICU admission, and mortality. Assessment and management of such devastating casualties require a complex and multidisciplinary approach.
