To explore the utility of proactive identification of COPD in patients 75 years of age and older in a Canadian primary care setting.<jats:italic>Methods.<\/jats:italic>Canadian Thoracic Society (CTS) screening questions were administered to patients with a smoking history of 20 pack-years or more; those with a positive screen were referred for postbronchodilator spirometry.<jats:italic>Results<\/jats:italic>. A total of 107 patients (21%), of 499 screened, had a 20-pack-year smoking history; 105 patients completed the CTS screening. Forty-four (42%) patients were positive on one or more questions on the screening; significantly more patients with a previous diagnosis of COPD (64%) were positive on the CTS compared to those without a previous diagnosis of COPD (30%). Of those who were not previously diagnosed with COPD (<jats:italic>N<\/jats:italic>= 11), four (36%) were newly diagnosed with COPD.<jats:italic>Conclusion<\/jats:italic>. A systematic two-stage method of screening for COPD, using CTS screening questions followed by spirometric confirmation, is feasible in the context of a busy primary care setting. More research is needed to assess the value of restricting screening to patients with a smoking history of 20 pack-years and on the sensitivity and specificity of these measures.<\/jats:p>","DOI":"10.1155\/2016\/1083270","type":"journal-article","created":{"date-parts":[[2016,6,23]],"date-time":"2016-06-23T11:49:19Z","timestamp":1466682559000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Office-Based
