Predicting mortality and admission duration for burns patients in Queensland, Australia: a retrospective cohort study.

In our institution, mortality was increased by 8.6% for each additional year of age and by 11.3% for each additional percentage total body surface area. Likewise, admission duration was prolonged by 1 day for every 7 years of increased age, by 1 day for each additional percentage total body surface area or by 7 days if surgery was required. These models have been incorporated into a set of prediction tables for mortality and admission duration for use in our institute that can guide patient and family discussions.
