   so only 6% of CAM visits discussed vitamin D and the immune system ( 15% X 40%)
     but NONE of the conventional doctors vitamin D and the immune system

BACKGROUND: Little is known about how providers communicate recommendations when scientific uncertainty exists.

OBJECTIVES: To compare provider recommendations to those in the scientific literature, with a focus on whether uncertainty was communicated.

DESIGN: Qualitative (inductive systematic content analysis) and quantitative analysis of previously collected audio-recorded provider-patient office visits.

PARTICIPANTS: Sixty-one providers and a socio-economically diverse convenience sample of 603 of their patients from outpatient community- and academic-based primary care, integrative medicine, and complementary and alternative medicine provider offices in Southern California.

MAIN MEASURES:
Comparison of provider information-giving about vitamin D to professional guidelines and scientific information for which conflicting recommendations or insufficient scientific evidence exists; certainty with which information was conveyed.

RESULTS:
Ninety-two (15.3 %) of 603 visit discussions touched upon issues related to vitamin D testing, management and benefits.

  • Vitamin D deficiency screening was discussed with 23 (25 %) patients, the
  • definition of vitamin D deficiency with 21 (22.8 %), the
  • optimal range for vitamin D levels with 26 (28.3 %),
  • vitamin D supplementation dosing with 50 (54.3 %), and
  • benefits of supplementation with 46 (50 %).

For each of the professional guidelines/scientific information examined, providers conveyed information that deviated from professional guidelines and the existing scientific evidence. Of 166 statements made about vitamin D in this study, providers conveyed 160 (96.4 %) with certainty, without mention of any equivocal or contradictory evidence in the scientific literature. No uncertainty was mentioned when vitamin D dosing was discussed, even when recommended dosing was higher than guideline recommendations.

CONCLUSIONS AND RELEVANCE:
Providers convey the vast majority of information and recommendations about vitamin D with certainty, even though the scientific literature contains inconsistent recommendations and declarations of inadequate evidence. Not communicating uncertainty blurs the contrast between evidence-based recommendations and those without evidence. Providers should explore best practices for involving patients in decision-making by acknowledging the uncertainty behind their recommendations.
