    Result interpretation


     
    • The APACHE II score was initially presented and validated in this study by Knaus, et. al. that prospectively enrolled 5815 patients from 13 hospitals. Complete data on all 12 physiologic measurements was only available for 5030 patients. The APACHE II score was shown to have good prognostic value in acutely ill patients.
     
    • This study prospectively validated the APACHE II score in 1721 consecutively admitted patients in a single center. The area under the ROC curve was higher than 0.8. The patient population was mostly comprised of surgical patients however.
