Study analyzes physicians' and nurses' use and recommendation of dietary supplements.
According to a new "Like ... supplemented" Healthcare Professionals (HCP) Impact Study, more than three-quarters of U.S. physicians (79%) and nurses (82%) recommend dietary supplements to their patients. The study also found that an almost equal number--72% of physicians and 89% of nurses--personally use vitamin, mineral, herbal and other supplements either regularly, occasionally or seasonally, which is a higher percentage than the 68% of adults who reported they take nutritional or dietary supplements.
The 2007 "Life ... supplemented" HCP Impact Study on dietary supplements was designed to evaluate the personal attitudes and use of dietary supplements by physicians and nurses and to determine if those factors impact whether they recommend supplements for their patients. The study was sponsored by the "Life ... supplemented" consumer wellness campaign, which is managed by the Council for Responsible Nutrition (CRN) Washington, D.C.
So who recommends supplements? Of the 72% of physicians who use supplements, 85% also recommend them to their patients; and of the 28% of physicians who do not use supplements, three out of five (62%) still recommend them.
"It is common sense that physicians who personally take supplements also recommend them to their patients," said Donnica Moore, MD, president of the Sapphire Women's Health Group and a member of the study's physician advisor team. "It's interesting that the majority of physicians who don't use supplements still recognize their patients may benefit from them. Although the study doesn't provide an explanation, it may simply be that physicians recommend supplements to their patients for specific conditions that don't apply to the physician's own personal health."
The number of physicians recommending dietary supplements to their patients is highest among obstetrician/gynecologists (OB/GYNs) (91%), followed by primary care physicians (84%). In addition, the study shows that almost three-quarters of physicians (72%) and more than three-quarters of nurses (88%) say it is a good idea for patients to take a multivitamin.
According to Dr. Moore, "lt makes sense to me that OB/GYNs are the group most likely to recommend supplements, although I am concerned that not all OB/GYNs reported they recommend them for their prenatal patients, given that women's health--especially prenatal--is one arena where the data supporting supplement use is overwhelmingly positive."
Given the current state of the science, it is not surprising that increasing numbers of healthcare professionals are incorporating dietary supplements into their personal health routines, says Tieraona Low Dog, MD, director of education, Program in Integrative Medicine, and clinical assistant professor, Department of Medicine, University of Arizona Health Sciences. However, she points out, the fact that only 25% of physicians actively counsel patients regarding their dietary supplement use demonstrates an ongoing and concerning problem that requires more outreach and education.
Paula Gardiner, MD, an assistant professor at Boston University Medical Center, who has conducted several surveys on the use of dietary supplements by physicians and is a member of the study's physician advisor team, cites the need for additional research, saying: "It is critical to better understand how healthcare professionals recommend dietary supplements to their patients and how we can support educational initiatives to encourage dialogue between HCPs and their patients about the proper use of dietary supplements."
Almost three-quarters of physicians (72%) and even more nurses (87%) reported they personally ask their patients about their use of dietary supplements. Also, 40% of physicians and 43% of nurses report that when discussing supplements with their patients, they, not their patients, are the ones who bring up the subject most often. Only 13% of physicians and 1% of nurses agreed with the statement "no one in my practice inquires about which dietary supplements patients are taking."
The "Life ... supplemented" HCP Impact Study of 1177 healthcare professionals (300 primary care physicians, 301 OB/GYNs, 299 other physician specialists and 277 registered nurses and nurse practitioners) was conducted online in early October by Ipsos-Public Affairs. A nominal honorarium was given to each healthcare professional completing the survey.
