Mortality rate and factors associated with death in traumatic chest injury patients: A retrospective study

Traumatic chest injury is responsible for 10%–15% of all trauma-related hospital admissions across the world. It is also responsible for approximately 25% of trauma related death. Several predictors have been described for mortality following chest trauma however, limited published studies were available in Ethiopia. To assess mortality rate and factors associated with death in traumatic chest injury patients over five year's period from June 2016 to June 30, 2020 G.C. A retrospective cross-sectional study was done from June 2016 to June 30, 2020. Data was collected from patients’ chart. The collected data was entered into Epi-info version 7 and transferred to SPSS version 20.0 for processing and analysis. Bivariable and multivariable logistic regression was used to show factors associated with mortality. P- Value 50 year [AOR 9.32, 95% CI, 2.72–31.86], late presentation beyond 6hr (AOR 7.17, 95% CI 1.76–29.21), bilateral chest injury (AOR 3.58 95% CI 1.53–8.38), penetrating chest injury (AOR 3.63 95% CI 1.65–7.98), presence of extra-thoracic injury (AOR 4.80, 95% CI, 1.47–15.72) and need for mechanical ventilation (AOR 11.18, 95% CI 2.11–59.23). The mortality rate in traumatic chest injury was high. Late presentation beyond 6hr, age >50-year, penetrating injury, bilateral chest injury, associated extra thoracic injury, and need for mechanical ventilation were identified as possible risk factors for mortality in traumatic chest injury patients. •Globally chest trauma related hospital admission was 10–15%.•In our study the overall mortality rate of traumatic chest injury was 26%.•Late presentation, older age and others were associa
