Abstract
Background: Several factors such as age, gender, burn depth, and inhalation injury have been associated with the mortality from burn injuries. While studies have looked at the association between these factors and burn mortality with varying results, very few studies in our region have focused on which of these parameters can be used to predict burn mortalities. This study was carried out to establish the current mortality rate from thermal burn, and to identify the predictors of burn mortality.
Method: This was a ten-year retrospective review of thermal burn injuries in our burn center. statistical tests were done using Chi-square, multivariate, and multiple linear regression analysis.
Result: A total of 595 thermal burn injuries were seen in the period under review, with a mortality rate of 19%. Mortality rate was higher in females (20%) than males (18%), p=0.491. Shorter hospital stays (p=<0.001), presence of inhalation injury (p=<0.001), thermal etiology (p=<0.001), as well as increasing age (p=<0.001), Total Body Surface Area [TBSA] (p=<0.001), burn depth (p=<0.001) were associated with mortality. However, only burn depth (β=0.241, p=<0.001) and TBSA (β=0.473, p=<0.001) were found to be significant predictors of mortality.
Conclusion: Only burn depth and TBSA are significant predictors of mortality.
