The factors influenced on the length of hospital stay in burn patients.

ABSTRACT

The aim of this study was to analyse association between the factors ; (the extent of burn, patient’s age, type of micro-organism, severity of infection and patient’s past medical illness) and the length of hospital stay among 147 survived burn patients who were admitted to the Burn Unit, Siriraj Hospital during January 1, 1994 to August 31, 1997. By using analysis of variance (ANOVA) for bivariate analysis. It was found that statistical significant determinants for variance in the length of hospital stay were extent of burn (F=43.130, df=1,145, p-value<0.0001), type of micro-organism (F=40.792, df=1,145, p-value<0.0001). severity of infection (F=24,409, df=1,145, p-value<0.0001), and type of burn (F=12.815, df=1,145, p-value<0.0001). When we entered these 4 influential independent variables in a final multiple classification analysis, the total explained variance in the length of hospital stay was 44.4% whereas the explained variance were 12.25%, 10.24%, 3.61% and 3.61% for extent of burn, type of micro-organism, severity of infection and type of burn, respectively.
