What were the findings (excerpted from the Abstract)?

The purpose of this study was to assess participant-level results from the first 4 years of implementation of the National Diabetes Prevention Program (National DPP), a national effort to prevent type 2 diabetes in those at risk through structured lifestyle change programs. Descriptive analysis was performed on data from 14,747 adults enrolled in year-long type 2 diabetes prevention programs during the period February 2012 through January 2016. Data on attendance, weight, and physical activity minutes were summarized and predictors of weight loss were examined using a mixed linear model. Participants attended a median of 14 sessions over an average of 172 days in the program (median 134 days). Overall, 35.5% achieved the 5% weight loss goal (average weight loss 4.2%, median 3.1%). Participants reported a weekly average of 152 min of physical activity (median 128 min), with 41.8% meeting the physical activity goal of 150 min per week. For every additional session attended and every 30 min of activity reported, participants lost 0.3% of body weight.

Why is this important?

During the first 4 years, the National DPP has achieved widespread implementation of the lifestyle change program to prevent type 2 diabetes, with promising early results. As with many programs to prevent diabetes, greater duration and intensity of session attendance resulted in a higher percent of body weight loss overall and for subgroups. Focusing on retention may improve overall program results. Further program expansion and investigation is needed to continue lowering the burden of type 2 diabetes nationally. The Centers for Medicare & Medicaid Services (CMS), on July 7, 2016, proposed to expand diabetes prevention efforts through introduction of the Medicare Diabetes Prevention Program (MDPP) starting January 1, 2018. The 2017 Physician Fee Schedule released several finalized policies for the MDPP. The policies included the definition of the MDPP benefit, beneficiary eligibility criteria, and supplier eligibility and enrollment criteria. Future rulemaking will address policies related to payment, virtual providers, and other program integrity safeguards. This is the first time a preventive service model from the CMS Innovation Center has been expanded. Have you been reading about the new MDPP intervention? Do you intend to participate as an MDPP Provider?
