The Acute Physiologic Score and Chronic Health Evaluation (APACHE) II and the Simplified Acute Physiologic Scale (SAPS) II are two of the more commonly employed predictors of outcome and performance in the intensive care unit setting. However, controversy persists about whether the scores generated by these systems have similar predictive value. This study compared the predicted mortalities derived from @entity697 and contrasted them to the actual mortality in a @entity954 ( @entity954 ). Data for 1665 @entity1 admitted to the @entity954 between July 1994 and August 1997 were entered into an @entity954 computerized database. From recorded demographic, hemodynamic, and laboratory data, @entity697 scores were obtained with corresponding predicted mortalities. @entity1 were stratified by age into categories of less than and greater than 65 years old. Predicted mortalities by @entity697 were compared for each group. An additional analysis included a comparison of survivors and nonsurvivors. There was no significant difference in predicted mortality between @entity697 in any of the groups. Actual mortality was 30 of 486 (6.2%) in @entity1 less than 65 years of age and 73 of 1179 (6.2%) in @entity1 65 years of age or greater. The @entity697 predicted mortalities (mean +/- SD) for @entity1 less than 65 years of age were 10.5% +/- 10.6% and 10.9% +/- 13.3%, respectively (P > .05). The @entity697 predicted mortalities in @entity1 65 years of age or greater were 19.1% +/- 17.8% and 18.7% +/- 21.0%, respectively (P > .05). Similarly, when @entity1 were stratified by survival status, no significant difference was present between groups. However, in individual @entity1 , a difference between @entity697 scores was often present. We conclude that although disparities between @entity697 predicted mortalities in individual @entity1 may be significant, @entity697 have similar predictive value in a large @entity954 @entity1 population. However, both @entity697 systems overestimate mortality in @entity954 @entity1 . Based on our results, we conclude that either system can be used to measure quality of care in the @entity954 ; however, neither system can be reliably applied to a single @entity1 .
