Analysis of prognostic indexes and other parameters to predict the length of hospitalization in thermally burned patients.
BACKGROUND
In a retrospective study the influence of several clinical data and prognostic indexes on the length of hospital stay in burned patients was investigated.


METHODS
We recorded all admitted patients from January 2004 to December 2005 except for electrical and chemical injuries or patients that died during recovery. Age, gender, weight, height, body surface area, fluid, caloric and protein delivery, Total Burn Surface Area, full thickness burn surface area, Roi index, Baux score, Unit Burn Standard index, Abbreviated Burn Severity Index and the length of hospitalization were registered. A univariate and multivariate analysis was performed to look for correlations between these parameters and the length of hospitalization.


RESULTS
We recorded eligible 233 patients. The univariate analysis showed that age, protein and caloric delivery, Roi index and ABSI were significantly related with the length of hospitalization while, at the multivariate analysis, only Roi index was related (p<0.05). However, Roi index was able to predict only 5.5-6% of cases.


CONCLUSIONS
A correlation exists between the length of hospital stays and the Roi index in burned patients but does not explain the bulk of evidence. Further studies are required to investigate this relation, to screen other parameters and to correlate them with measures of outcome, i.e. functional (the range of motion of articulations) or aesthetic (patient's self assessment of his body image).
