    MASCC Risk Index for Febrile Neutropenia

    Identifies patients at low risk for poor outcome with febrile neutropenia.

    INSTRUCTIONS

    Use in neutropenic patients (see ANC calculator) with fever at least 100.4°F (38ºC). Do not use in patients with acute leukemia undergoing induction chemotherapy or allogeneic hematopoietic stem cell transplant conditioning, per IDSA guidelines.

    When to Use
    Pearls/Pitfalls
    Why Use
    • Use at fever onset to assess risk of complications in febrile neutropenia for patients undergoing chemotherapy treatment.
    • Use after addressing immediate concerns to identify patients who may not need to be admitted to the hospital or could be discharged early.
    • Only applies to adult patients.
    • Validated as a dichotomous outcome; i.e., low risk versus not low risk. Obviously, patients who are “not low risk” have varying degrees of risk.

    Febrile neutropenia is a potentially life-threatening complication of chemotherapy, but some patients are at low risk for serious complications. The MASCC Risk Index is an internationally validated scoring system that identifies these low risk patients that can potentially be treated as an outpatient with early antibiotics.
