A Protocol to Deliver Intensive Behavioral Therapy (IBT) for Obesity in Primary Care Settings: The MODEL-IBT Program

The Centers for Medicare and Medicaid Services (CMS) initiated coverage of intensive behavioral therapy (IBT) for obesity in 2011, providing beneficiaries 14 to 15 brief, individual counseling visits in 6 months. CMS offered general recommendations for delivering IBT but did not provide an evidence-based treatment protocol, which was the objective of the present research.

This review describes the evidence that CMS considered in developing its IBT benefit. It also examines weight losses produced by the intensive lifestyle intervention in the Diabetes Prevention Program (DPP), as well an adapted version of the DPP delivered (for the first 6 months) on the visit schedule recommended by CMS. This new protocol, which was evaluated in a recent randomized trial, provided 14 visits in the first 24 weeks, with 7 additional monthly visits through week 52.

As reported previously, the 50 participants with obesity assigned to the new IBT protocol lost a mean of 5.4% of their initial weight at week 24; 46% of participants lost ≥ 5% of their baseline weight. At 1 year, the mean loss was 6.1%, and 44% of participants lost ≥ 5%.

With these generally favorable results, the IBT protocol is being posted online for practitioners and researchers to use.
