    CURB-65 Score for Pneumonia Severity

    Estimates mortality of community-acquired pneumonia to help determine inpatient vs. outpatient treatment.

    IMPORTANT

    We launched a COVID-19 Resource Center, including a critical review of recommended calcs.

    Tips for COVID-19: Use after diagnosis to determine dispo. May have some value in COVID-19.

    When to Use
    Pearls/Pitfalls
    Why Use

    The CURB-65 calculator can be used in the emergency department setting to risk stratify a patient’s community acquired pneumonia.

    • The CURB-65 Score includes points for confusion and blood urea nitrogen, which in the acutely ill elderly patient, could be due to a variety of factors. An alternative scoring system, SOAR, circumvents those two parameters. It uses low systolic BP (S) and poor oxygenation (PaO2: FIO2) (O), advancing age (A), high respiratory rate (R).
    • CURB-65 does not assign points for co-morbid illness and nursing home residence, as the original study did account for many of these conditions.
    • CURB-65 may not identify patients requiring ICU admission as well as the PSI.
    • CURB-65 is fast to compute, requires likely already-available patient information, and provides an excellent risk stratification of community acquired pneumonia. It can facilitate better utilization of resources and treatment initiation.
    • In comparison to the PSI, CURB-65 offers equal sensitivity of mortality prediction due to community acquired pneumonia. Notably, CURB-65 (74.6%) has a higher specificity than PSI (52.2%).
