Length of surgical intensive care unit stay and risk factors.
OBJECTIVE
To assess length of stay of patients in the surgical intensive care unit (ICU) and to determine risk factors for a long ICU stay.


METHODS
Review of retrospective data.


METHODS
University hospital surgical ICU.


METHODS
Out of a total of 681 admissions to the surgical ICU during a one year period (July 1, 1996 - June 30, 1997), 613 had complete medical data which were analysed.


RESULTS
The frequency distribution was skewed to the right. The median and mode were the same (2 days). 35.89 per cent of the ICU admissions had a long stay (>2 days). Independent risk factors for a long ICU stay in the multivariate logistic regression analysis are increasing age, unstable condition, long weaning time, diuretic therapy and re-operation.


CONCLUSIONS
Knowing the length of ICU stay, risk factors for a long ICU stay and how to shorten the ICU stay have potential application in optimizing ICU resource planning and decreasing the health care cost.
