What is the SAPS II score range and interpretation?

SAPS II scores range from 0 to 163. The score is converted to a predicted in-hospital mortality using a logistic regression equation. A score of 40 corresponds to ~25% predicted mortality; a score of 60 corresponds to ~50%; scores above 80 predict >80% mortality. The score uses 15 physiological variables plus age and admission type.

How does SAPS II differ from SAPS 3?

SAPS II was developed in the early 1990s on European and North American ICUs and uses variables collected over the first 24 hours. SAPS 3 was developed in 2005 on a global dataset and uses variables available at ICU admission time, making it more practical for rapid admission assessment and better calibrated for contemporary international ICU populations.
