How is SAPS III different from SAPS II in timing?

SAPS III uses data from a 1-hour window around ICU admission, unlike SAPS II/APACHE II which use worst values in the first 24 hours. This provides immediate prognostic information at admission for triage and family communication. Customized equations available for different geographic regions (Europe, Americas, Oceania) improve calibration.

What components are scored in SAPS III?

Box I (pre-ICU admission): age, LOS before ICU, comorbidities (cirrhosis, HF, alcohol, cancer, etc.), surgery status. Box II (admission reasons): 6 admission categories. Box III (physiology at admission): 12 variables including GCS, bilirubin, creatinine, temperature, HR, WBC, platelets, FiO2. Total maximum is approximately 217 points.
