Nurses, physicians, and allied health professionals at the IWK Health Centre, Halifax, NS, Canada, a tertiary care, regional center for a population of 2.5 million were surveyed. We examined personal attitudes and professional practice in addressing the use of complementary and alternative medicine (CAM) use by patients. We also examined the availability of CAM-related information to health professionals. The findings suggest that health professionals: (1) are supportive of the use of selected CAM therapies by patients; (2) have almost no personal experience of CAM; (3) have limited knowledge about CAM and acquire that information mainly from the Internet, friends or family rather than professional journals; (4) are uncomfortable discussing CAM with patients and; (5) rarely or never ask patients about CAM use. We have identified barriers for health professionals to effective communication about CAM use by their patients and families. Improved access to existing policies and scientific publications, and specific continuing professional development opportunities focused on speaking openly and non-judgmentally with patients are likely to enhance accurate guidance of patients in the highly prevalent use of CAM.
