    Rapid Emergency Medicine Score (REMS)

    Predicts in-hospital mortality in nonsurgical adult patients presenting to the ED.
    When to Use
    Pearls/Pitfalls
    Why Use

    • Critically ill patients, where in-hospital mortality prediction may help guide treatment modalities.

    • Not validated for pediatric patients.

    Not validated for pediatric patients.

    • May not add to clinician gestalt, but can be useful in the prehospital setting for determining whether a patient would benefit from rapid access to advanced life support services.

    • Superior (Olsson 2004) to the Rapid Acute Physiology Score (RAPS) (Rhee 1987) and non-inferior to APACHE II (Olsson 2003).

    • Calculated with values obtained out of hospital, or in hospital without lab studies.

    • Helps guide aggressiveness of treatment with parameters routinely acquired in the prehospital setting.
