    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Simplified Acute Physiology Score (SAPS) 3

    Estimates the probability of mortality for ICU patients on admission.

    INSTRUCTIONS

    The SAPS 3 Score predicts hospital mortality upon ICU admission, using patient characteristics, indication for ICU admission, and physiologic derangement upon ICU admission.

    When to Use
    Pearls/Pitfalls
    Why Use

    Upon admission to the ICU to predict hospital mortality.

    Physiologic variables are meant to be assessed within 1 hour of ICU admission.

    The authors hypothesize that patient factors and circumstances surrounding ICU admission — combined with a patient's physiologic derangements upon ICU admission — gives a better picture of an ICU patient's prognosis.
