Abstract
BACKGROUND/AIMS: The REAL HEALTH -Diabetes Study is a practice-based clinical trial that adapted the Look AHEAD lifestyle intervention for implementation in primary care settings. The trial will compare the effectiveness and cost-effectiveness of in-person group lifestyle intervention, telephone group lifestyle intervention, and individual medical nutrition therapy (MNT), the current recommended standard of care in type 2 diabetes. The primary outcome is percent weight loss at 6 months with outcomes also measured at 12, 18, 24 (intervention completion), and 36 months. Here, we describe the adaptation, trial design, implementation strategies, and baseline characteristics of enrolled participants. METHODS: The study is a three-arm, patient-level, randomized trial conducted in three community health centers (CHCs) and one diabetes practice affiliated with one academic medical center. RESULTS: The study used existing clinical infrastructure to recruit participants from study sites. Strategies for successful conduct of the trial included partnering with health-center based co-investigator clinicians, engaging primary care providers, and accommodating clinical workflows. Of 248 eligible patients who attended a screening visit, 211 enrolled, with 70 randomly assigned to in-person group lifestyle intervention, 72 to telephone group lifestyle intervention, and 69 to MNT. The cohort was 55% female, 29% non-white, with mean age 62 years and mean BMI 35 kg/m2. Enrollment rates were higher at CHC sites. CONCLUSIONS: A practice-based randomized trial of a complex behavioral lifestyle intervention for type 2 diabetes can be implemented in community health and usual clinical settings. Participant and provider engagement was higher at local CHC sites reflecting the study implementation focus. CLINICAL TRIAL REGISTRATION: NCT02320253.
