The SAPS 3 prognostic model consists of 3 boxes scoring various findings on ICU admission. Box III reflects physiologic measures taken on admission. The authors are the SAPS 3 Investigators from across Europe.
Parameters:
(1) lowest Glasgow Coma Scale (GCS)
(2) total serum bilirubin in mg/dL or µmol/L
(3) highest body temperature in °C
(4) serum creatinine in mg/dL or µmol/L
(5) highest heart rate in beats per minute
(6) highest white blood cell count per µL or per L
(7) lowest arterial pH
(8) lowest platelet count per µL or per L
(9) lowest systolic blood pressure in mm Hg
(10) oxygenation and respiratory support

where:
• The data elements are described in documents at www.saps3.com
total score for Box III =
= SUM(points for all 10 parameters)
Interpretation:
• minimum score: 0
• maximum score: 82
• The higher the score the greater the physiologic disturbance.
