Knowledge and Use of Office Spirometry for the Detection of Chronic Obstructive Pulmonary Disease by Primary Care Physicians

BACKGROUND: The importance of office spirometry has been strongly advocated in the pulmo-nary community, but whether its importance is recognized and accepted by primary care physicians is less well established. METHODS: To assess primary care physicians ’ knowledge and use of office spirometry for the detection of chronic obstructive pulmonary disease, we conducted a brief mail survey on the local practice of office spirometry, barriers to performing office spirometry, and general knowledge about spirometry. We also provided 60-min educational workshops to assess whether such an approach would increase spirometry testing or perceptions about spirometry. RESULTS: Twenty-nine of 57 (51%) primary care offices responded to the survey. Of these, 66% owned their own spirometer. The most common reasons for not performing spirometry were uncertainty about the impact of the test (41%), physician and staff unfamiliarity (38%), and lack of training (34%). Twenty-one respondents participated in the workshops. In the 3 months follow-ing the workshops, the number of spirometry tests increased by 59 % (p 0.004). After the workshops, the proportion of clinics that reported reasons for not performing the test decreased by 13 % (p 0.01), but important barriers to performing office spirometry were still present, including physician and staff unfamiliarity (22%), uncertain interpretation of results (22%), time (22%), and reimbursement (22%). CONCLUSIONS: The general knowledge and use of office spirometry in the primary care community is poor, but can be improved, at least in the short-term, by a simple educational workshop.
