[Application of the Simplified Acute Physiology Score II (SAPS II) in a medical intensive care unit].
OBJECTIVE
Our study was to assess the validity of SAPS II (New Simplified Acute Physiology Score) to predict the probability of in hospital mortality, in a cohort of patient admitted to a medical intensive care unit.


METHODS
Prospective study.


METHODS
Out of 467 the 525 patients admitted were included. SAPS score and in hospital mortality prediction were calculated for each of them.


RESULTS
In this group, SAPS II offered a satisfactory discrimination power with an area under the curve of 0.843. However, calibration showed a lack of fit (chi 2 = 28.5, P < 0.001), with an overall under prediction of mortality (observed versus expected ratio of 1.12).


CONCLUSIONS
This SAPS II lower predicting accuracy in a specific population and for individual outcome prediction may reduce its interest in clinical decision-making.
