Primary Care Physicians', Nurse Practitioners' and Physician Assistants' Knowledge, Attitudes and Beliefs Regarding COPD: 2007 To 2014.

To assess current primary care physicians', nurse practitioners' (NP) and physicians assistants' (PA) knowledge, attitudes and beliefs regarding chronic obstructive pulmonary disease (COPD) and changes from a similar 2007 assessment, we surveyed attendees of 3 regional continuing medical education programs and compared the 2013/2014 responses with responses to a similar survey completed in 2007. Survey data included information on personal demographics, agreement with perceived barriers to COPD diagnosis, awareness, and use of COPD guidelines, and beliefs regarding the value of available COPD therapies. In 2013/2014, 426 primary care clinicians (278 medical doctors [MDs] and doctors of osteopathic medicine [DO] and 148 NPs/PAs) provided useable responses (overall response rate 61%). Overall these physicians were older and more experienced than the NPs/PAs but with few other differences in responses except significantly greater physician reported use of spirometry for COPD diagnosis. About half of the clinicians reported having in-office spirometers but less than two thirds reported using them for all COPD diagnoses. All respondents reported multiple barriers to COPD diagnosis but with fewer than in 2007 reporting lack of knowledge or awareness of COPD guidelines as a major barrier. The most striking difference between 2007 and 2013/2014 responses was the marked increase in beliefs by all clinicians in the ability of COPD treatments to reduce symptoms and numbers of exacerbations. These data affirm that primary care clinicians continue to report multiple barriers to COPD diagnosis including lack of easy access to spirometry and frequent failure to include spirometry in diagnostic confirmation. However, since 2007, the clinicians report a remarkable decline in therapeutic nihilism, which may enhance their interest in learning more about diagnosing and managing COPD.
