burn mortality statistics may be misleading unless they account properly for the many factors that can influence outcome. such estimates are useful for patients and others making medical and financial decisions concerning their care. this study aimed to define the clinical, microbiological and laboratorial predictors of mortality with a view to focus on better burn care. data were collected using independent variables, which were analyzed sequentially and cumulatively, employing univariate statistics and a pooled, cross-sectional, multivariate logistic regression to establish which variables better predict the probability of mortality. survivors and non-survivors among burn patients were compared to define the predictive factors of mortality. mortality rate was 5.0%. higher age, larger burn area, presence of fungi in the wound, shorter length of stay and the presence of multi-resistant bacteria in the wound significantly predicted increased mortality. the authors conclude that those patients who are most apt to die are those with age > 50 years, with limited skin donor sites and those with multi-resistant bacteria and fungi in the wound.
