Hansted AK, et al. - Researchers evaluated the Acute Physiology and Chronic Health Evaluation (APACHE) II score for its predictive value in emergency abdominal surgical patients and performed a comparison between the APACHE II score vs the American Society of Anesthesiologists (ASA) physical status score and the Charlson Comorbidity Index (CCI). This study included 885 patients. Evaluation of the APACHE II score was done with the area under the receiver operating characteristics curve (AUROC) statistics. For 30-day mortality, for 90-day mortality, and for admission to the intensive care unit, the AUROC (95% confidence interval) of the APACHE II score was identified to be 0.72 (0.65-0.80), 0.70 (0.64-0.76), and 0.65 (0.59-0.71), respectively. As far as the prediction of 90-day mortality was concerned, a better performance was displayed by the CCI. They found all other results for the ASA score and CCI were comparable with the APACHE II score. In emergency abdominal surgical patients, a moderate prediction of mortality and poor prediction of admission to intensive care unit was enabled by the APACHE II score.
