    Simplified Acute Physiology Score (SAPS) II

    Estimates mortality in ICU patients, comparable to APACHE II.

    INSTRUCTIONS

    Use the worst values in the past 24 hours.

    When to Use
    Pearls/Pitfalls
    Why Use

    ICU patients.

    • The worst physiological variables, corresponding to the highest number of points, should be collected within the first 24 hours of ICU admission.
    • Superior to the original SAPS system, exhibiting a higher AUROC (0.86) than the original (0.80).
    • Burn and cardiac patients were excluded from the original study, so while there is some evidence suggesting that SAPS II may perform well for these patient groups, this area requires study before SAPS II is used for these patients.
    • Estimates mortality risk for a group of patients, but is not intended to describe an individual patient's chance of survival.

    Can be used to measure quality of care in the ICU (but should not be used to predict survival of an individual).
