    Ottawa COPD Risk Scale

    Predicts 30-day mortality or serious adverse events (MI, intubation, etc) in ED patients with COPD.
    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).
