Tool identifies patients with COPD at risk for serious complications
The Ottawa COPD Risk Scale — which assessed a combination of 10 factors — ascertained which patients with COPD were more likely to have short-term serious outcomes better than current practice, according to findings recently published in the Canadian Medical Association Journal. Ian G. Stiell, MD, MSc, and colleagues had previously developed the Ottawa COPD Risk Scale, a 10-item questionnaire that allocates one to three points based on the following: histories of coronary artery bypass graft, peripheral vascular disease intervention and respiratory distress intubation, X-ray results with pulmonary congestion; ECG with acute ischemic changes; heart rate on ED arrival; hemoglobin less than 100 g/L; urea of 12 mmol/L; and serum CO2 of 33 mmol/L.
