    SAVE (Survival after Veno-Arterial ECMO) Score

    Predicts in-hospital survival in adult patients after VA ECMO for refractory cardiogenic shock.

    When to Use
    Pearls/Pitfalls
    Why Use

    • Patients with refractory cardiogenic shock in whom veno-arterial (VA) ECMO is being considered.

    • Do not use in patients receiving veno-venous (VV) ECMO (see RESP Score).

    • Only predicts survival to hospital discharge and does not predict neurologic function or functional status, which may be important considerations.

    • The score was derived from a cohort of patients who were placed on VA ECMO, and likely excluded many patients who may have had different survival rates.

    • Patients receiving CPR during cannulation (eCPR) were not included in the derivation of the SAVE Score; therefore, the score may not apply to these patients.

    ECMO is a resource-intensive endeavor with high morbidity, and patients should be selected carefully. Survival estimates may aid the decision process.

    Advice

    Other factors may contribute to the decision to initiate ECMO (e.g. life expectancy, quality of life, resource availability).

    Management

    We are not aware of any guidelines that incorporate the SAVE Score, but survival prediction may be incorporated into the decision to initiate VA ECMO.

    Critical Actions

    Comprehensive decision-making should not be based solely on one prediction rule, and the threshold to initiate ECMO may vary by institution.
