Predictors of mortality: a comparison between two burn wound treatment policies.

Retrospective review of outcomes and experiences of a single burn centre between two time periods during which a new wound care technique was employed after the first period. The time period was divided into two: 1977-1984 and 1984-1990. Due to the use of cerium nitrate-silver sulphadiazine, the introduction of serial excision and grafting became possible in the second time period. Multivariate risk-analysis was done by logistic regression analysis. The mortality rate decreased from 13.7% (1997-1983) to 4.7% (1984-1990). Results of multiple logistic regression analysis indicate that the change in periods was advantageous for patients with >50% TBSA, within the age group, 0 to 30 years. Obviously, the care which a patient receives has improved significantly. Many developments occurred simultaneously and it appears impossible to conclude that only the use of cerium nitrate-silver sulphadiazine was the reason for improved survival. Nevertheless, the use of cerium nitrate-silver sulphadiazine enables sequential excision and grafting and in consequence allows for many of these developments to occur.
