Online Lifestyle Medicine Continuing Medical Education (CME) Course Completion Predicts Increases in Clinician Knowledge, Confidence, and Practice of Lifestyle Medicine

<b>Introduction:</b> Despite growing evidence linking lifestyle changes to disease reversal, lifestyle medicine (LM) is not widely practiced. Lack of clinician training and knowledge is cited as a barrier to LM adoption. This study measures changes in LM knowledge, attitudes, confidence, and practice behaviors following completion of a 5.5-h, asynchronous, online continuing medical education (CME) course. <b>Methods:</b> Participants completed a pre- and post-course survey. A repeated-measures linear model tested changes in knowledge, confidence, interest, experience, and practice of LM, after adjusting for age, gender, race, ethnicity, clinical degree/licensure, and presence of a health system value-based care model. <b>Results:</b> Surveys from n = 2954 course participants were analyzed. Overall, statistically significant improvements were observed in self-reported knowledge (+.47 of points) and confidence (+.53 of points) of LM. Participants across the sample reported greater frequency (+.08 of 5 points) and reach (+.10 of 5 points) of LM with their patients (p<.0001 for both). <b>Discussion:</b> This study demonstrated that a brief, scalable, online CME course can improve LM knowledge, confidence, attitudes, and practice. Future research should examine long-term practice changes as well as differences in outcomes across types of healthcare professionals.
