Project MiNT: Assessing the Impact of Food & Video-Based Nutrition Education on Patients With Poorly Controlled Diabetes

This pragmatic randomized controlled trial will assess the efficacy of medically tailored meals and medical nutrition therapy via telehealth on clinical outcomes for patients with poorly controlled type 2 diabetes. The goal of these interventions is to improve outcomes for patients with diabetes by impacting self-care behaviors and diet self-efficacy in the short and long term. This study leverages a unique health system and community group partnership to inform the utility of reimbursement for medically tailored meal programs and medical nutrition therapy, which would ultimately facilitate their scalability and sustainability within the healthcare system.

Despite the availability of evidence-based guidance and treatments, many patients with diabetes mellitus (DM) do not achieve optimal glycemic control. In prior work, patients with DM identified primary needs of improved access to food and nutrition education. Several innovative models for food services have emerged to address patient needs for improved healthy food access. Currently, select non-profit organizations across the U.S. deliver millions of medically-tailored meals (MTM) to patients with chronic illnesses, based on the premise that food can be as helpful as medicine in improving patient outcomes. While a handful of pilot studies have demonstrated success of MTM in reducing healthcare utilization and hemoglobin A1c (HbA1c) among patients with DM, no randomized trials have assessed the sustained impact of MTM on long-term outcomes for patients with DM. Similarly, individual studies of medical nutrition therapy (MNT), which includes individualized nutrition education and counseling, have shown benefit for improving DM outcomes. However, uptake of MNT across health systems has historically been extremely limited because of patient logistical barriers to attending the in-person visits. MNT delivered by telehealth (tele-MNT) has potential to overcome these barriers. Our goal is to evaluate the effect of MTM, with and without additional tele-MNT, on outcomes for patients with poorly controlled type 2 DM. The investigators will conduct a pragmatic randomized controlled trial with patients who have poorly controlled DM. Outcomes of interest include change in HbA1c, cost effectiveness, weight, diabetes self-efficacy, self-care, diabetes quality of life, and patient satisfaction. Investigators will assess the efficacy of 1) MTM and 2) MTM + tele-MNT compared to usual care in reducing HbA1c at 3, 6 (primary outcome) and 12 months and the cost effectiveness of each intervention compared to usual care up to 12 months. Patient perspectives regarding experiences with MTM and MTM + tele-MNT will also be explored to gain a better understanding of potential factors contributing to treatment failure and success within each group. The proposed research is innovative because it develops and tests a novel tele-MNT intervention tailored to recipients of MTM, provides a comprehensive solution to patient-identified nutrition needs, includes complete utilization data provided by the HealthShare Exchange, and leverages a unique health system and community group partnership to improve sustainability and scalability. Study results will inform 1) provider and payor decisions regarding offering and covering these services; 2) how services should be structured for scalability; and 3) integration of these services into the larger care delivery system to reduce DM disparities.
