A Toolbox Approach to Obesity Treatment in Primary Care
Obesity is common, causing many medical problems in adults (e.g., diabetes, hypertension, high cholesterol, sleep apnea, heart attack, strokes). A range of treatments have shown to be effective for treating obesity. Treatments include lifestyle modification, meal replacements, and weight loss medication. Most primary care settings do not provide much obesity treatment, though, as primary care providers (PCPs) are not well trained and because reimbursement for treatments is not consistent. Hypothesis: If PCPs have training in weight management and if most costs of treatment are reimbursed, we surmise that a "toolbox" of treatments can produce a clinically important weight loss amount in a large group of patients. Design: We propose to establish a registry of obese patients with at least one common medical condition related to their weight. From the registry, we will randomly select 350 people to be offered treatments to assist with weight loss. The remainder of the registry's patients can still receive obesity treatment but will not be reimbursed. We will conduct the study at Denver Health, a large public health care system that treats a low income, ethnically diverse population. All 350 patients will be offered some self-monitoring tools for weight management and the chance to do a computer assessment to select the right treatment for weight loss. Patients who complete this and record their food intake and physical activity for 1 week will be offered a "Level 2" treatment for weight loss. Level 2 treatments include: a voucher for a commercial weight loss program; intensive group weight loss counseling; meal replacements; gym membership; or weight loss medication. Patients will choose which treatment they want, with the approval of their PCP. Researchers at Denver Health will help with the computer assessment and dispensing the treatments. We are interested in what percentage of patients lose at least 5% of their starting weight. We will also explore changes in glucose, blood pressure, and cholesterol, and we will look at how much this intervention costs and whether patients need less medication for their weight-related conditions at the end of the study. Impact: If the study is successful, we plan to take the results to the leaders at Denver Health to see if they will make obesity treatment more broadly available for all patients there.

Primary outcomes
- Percentage of Participants Who Achieved >5% Weight Loss at 12 Months — 1 year
Participants who had both a baseline and 12 month weight measurement were included. Weight change at 12 months was measured as a percent difference from their starting weight. - Health Care Utilization - Non-study Clinic Visits — 1 year study period
Evaluation of differences in health care resource utilization between Tool and Control groups during the study period. Health care resource utilization defined as the number of non-study clinic visits. - Health Care Utilization - Laboratory Measurements — 1 year study period
Evaluation of differences in health care resource utilization between Tool and Control groups during the study period. Health care resource utilization defined as the number of number of lab measurements taken during the period (including A1C, creatinine, and lipids).
