    When to Use
    Why Use
    • Patients presenting to the ED with acute COPD exacerbation. 
    • Should not be applied in patients who are obviously too ill for discharge (e.g. hypotensive, severe dementia, ischemic chest pain, etc).

    Risk-stratifying patients with acute COPD exacerbation can allow for safer disposition decisions (i.e., avoid admitting patients suitable for discharge, and avoid discharging patients at risk for adverse event).

    Advice

    Consider local practices when making disposition decisions. The study was conducted at 6 Canadian hospitals; in Canada, approximately 37.5% of emergency patients with COPD exacerbation, compared with 80% in the US (Stiell 2014).
