Abstract

Objective: Describe the content and frequency of provider-patient dietary supplement discussions during primary care office visits. Methods: Inductive content analysis of 1477 transcribed audio-recorded office visits to 102 primary care providers was combined with patient and provider surveys. Encounters were collected in Los Angeles, CA (2009-2010), geographically diverse practice settings across the United States (2004-2005), and Sacramento, CA (1998-1999). Results: Providers discussed 738 dietary supplements during encounters with 357 patients (24.2% of all encounters in the data). They mentioned: (1) reason for taking the supplement for 46.5% of dietary supplements; (2) how to take the supplement for 28.2%; (3) potential risks for 17.3%; (4) supplement effectiveness for 16.7%; and (5) supplement cost or affordability for 4.2%. Of these five topics, a mean of 1.13 (SD. =. 1.2) topics were discussed for each supplement. More topics were reviewed for non-vitamin non-mineral supplements (mean 1.47 (SD. =. 1.2)) than for vitamin/mineral supplements (mean 0.99 (SD. =. 1.1); p<. 0.001). Conclusion: While discussions about supplements are occurring, it is clear that more discussion might be needed to inform patient decisions about supplement use. Practice implications: Physicians could more frequently address topics that may influence patient dietary supplement use, such as the risks, effectiveness, and costs of supplements.
