There are more than 700,000 Veterans with severe obesity (body mass index >=35). These Veterans exert significant costs on the VA system, experience poorer quality of life, and have shortened lifespans. Bariatric surgery is the most effective treatment for severe obesity for weight loss, comorbidity resolution, and quality of life. Yet less than 0.5% of Veterans who qualify for bariatric surgery undergo it. Reasons for low utilization are unclear, although our preliminary research suggests that there are various patient, provider and system level barriers to severe obesity care.
This CDA proposal addresses the VA's urgent need to 1) understand the barriers to severe obesity care within VA; 2) test interventions designed to improve communication between providers and Veterans regarding severe obesity treatment options, including bariatric surgery and behavioral weight management strategies; and 3) characterize management practices surrounding severe obesity care within VA.
Aim 1 will include semi-structured interviews with Veterans with severe obesity and providers who treat them, including PCPs, MOVE! team members and bariatric surgery program members. Facilitators and barriers to bariatric surgery and MOVE! program participation as well as attitudes and experiences of providers and patients who have pursued bariatric surgery in VA will be identified. Aim 2 will include the development, refinement and pilot-testing of a communication tool designed to enhance shared decision-making for severe obesity treatment. For Aim 3, a national survey of VA PCPs will be administered in attempt to understand how PCPs manage severely obese patients and how severely obese patients engage with the MOVE! program.

The knowledge generated in this CDA will advance our understanding of the patient, provider and work system elements that contribute to low levels of bariatric surgery utilization. This will provide potential targets for optimizing clinical programs, such as MOVE! and bariatric surgery, that offer severe obesity care within the VA. It will also provide information on whether a communication tool designed to enhance shared decision-making is feasible and acceptable to Veterans and providers. Completion of these aims will provide the foundation for a future, multi-site randomized trial, evaluating the efficacy of the communication tool.
