    Severe Community-Acquired Pneumonia (SCAP) Score

    Predicts risk of adverse outcomes in CAP patients in the ED.

    Launched during COVID-19 crisis. COVID-19 Resource Center.

    Tips for COVID-19: Use to determine floor vs. ICU. Likely similar performance to SMART-COP.

    When to Use
    Pearls/Pitfalls
    Why Use

    In the ED, after diagnosis of community-acquired pneumonia is made, calculating SCAP may help predict the chance for "severe CAP", defined by adverse outcomes including inpatient mortality, septic shock, and/or need for mechanical ventilation.

    • High risk SCAP showed higher rates of adverse outcomes than high risk PSI and CURB-65, potentially helping choose which patients are at most need for the ICU with higher specificity (Yandiola 2009).
    • All validations were done in the same Spanish hospital network, by researchers from the same hospital, so may not be generalizable and there is still room for robust external validation.

    • If applying to a patient with potential COVID-19, keep in mind that age has a much stronger odds ratio for increasing mortality risk in COVID-19 patients than with other viral PNA patients.

    Assists with disposition decision after diagnosing CAP in the ED.

    Advice

    Threshold for disposition may change during resource-limited situations (such as the COVID-19 outbreak).

    Critical Actions

    If applying to a patient with potential COVID-19, use this score in conjunction with clinical suspicion and risk factors — particularly advanced age and comorbidities.
