Pilot Trial of the Nutrition-Supported Diabetes Education Program (NU-DSMP)

perjantai 14. lokakuuta 2022 päivittänyt: University of California, San Francisco

Pilot Study of the Nutrition-Supported Diabetes Education Program (NU-DSMP) Among Low-Income Adults With Type 2 Diabetes

This is a pragmatic, pilot randomized controlled trial (RCT) of the Nutrition-Supported Diabetes Education Program (NU-DSMP). This study will test the feasibility and preliminary impact of providing diabetes-tailored food support and individualized case-management on glycemic control and other intermediate outcomes including food security, diet, mental health, and health care behaviors, among Medicaid-enrolled patients with type 2 diabetes in a safety-net county health system.

Yksityiskohtainen kuvaus

Together with Contra Costa Health Services, a safety-net county health system, and Project Open Hand, a non-profit organization with extensive experience providing nutrition services to low-income, chronically ill individuals in the San Francisco Bay Area, the investigators will conduct the Nutrition-Supported Diabetes Education Program (NU-DSMP) Pilot Study. The goal for this pragmatic, pilot randomized trial is to test the feasibility, acceptability and preliminary impact of providing 12 weeks of diabetes-healthy food support (i.e. medically tailored meals and groceries) supported by individualized case-management to low-income individuals with type 2 diabetes mellitus (T2DM) participating in the evidence-based Diabetes Self- Management Program (DSMP), compared to DSMP participation alone.

The study will randomize 72 individuals 1:1 to intervention and control arms, following them at 0, 12 and 24 weeks with surveys and medical record review (with an interim brief 6 week assessment with the survey only), to understand the impact on diabetes health. Data from this pilot study will inform the planning of a full-size randomized trial to test the efficacy of the NU-DSMP model, with a long-term goal to inform policy debates about the value of implementing medically tailored food interventions as part of healthcare.

Aseet ja interventiot

Osallistujaryhmä / Arm
Interventio / Hoito
Ei väliintuloa: Standard of care including diabetes self-management education

Control participants will receive standard of care as offered by clinical partners to all T2DM patients, including referral to nutritional counseling, T2DM support groups, and participation in local diabetes self-management programs. Control participants are also often provided referral information for locally available food support services in the region that provide diabetes-appropriate foods. Control participants will participate in the Diabetes Self-Management Program, an evidence-based program that takes place over 6 weeks that meets the standard of care for diabetes education.

At the end of follow up, the control arm will receive three months diabetes-tailored food support consisting of diabetes-tailored grocery boxes and nutrition case-management.
Kokeellinen: Diabetes-tailored food support plus diabetes self-management education

The intervention has two components: 1) diabetes-tailored food support that consists of weekly, home-delivered medically tailored meals, and monthly home-delivered healthy groceries, from baseline to 24 weeks, and 2) three case-management sessions with client services staff from the partnering nutrition agency over the 12 weeks of intervention.

The intervention will be delivered in addition to a base condition consisting of remote participation in the Diabetes Self-Management Program, an evidence-based diabetes education program that takes place over 6 weeks also received by the control group as part of the standard of care.
Muut: Food support
Diabetes-tailored food support. Project Open Hand will provide intervention participants twelve weeks of supplemental food support. Food support will consist of a mix of meals tailored for T2DM, and T2DM-healthy groceries, consistent with American Diabetes Association (ADA) guidelines for diabetes healthy diets under the responsibility of a registered dietitian. All food support will be home delivered.
Muut: Case-management
Project Open Hand client services staff will conduct three case management sessions with the participant. The first session will initiate food services and ensure orientation to the intervention and set up delivery; the second session will support the participant with any issues related to the intervention (logistical or nutrition-related, with referral to the POH registered dietitian as needed); the third session will provide transition from the intervention, connect the participant with local food resources, and ensure a "warm hand-off" to nutrition

Aikaikkuna
Change in the proportion of participants with glucose control from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks

Baseline and twelve weeks
Change in health-related quality of life (healthy days) from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks
Health-related quality of life will be measured using the Summary Index of Unhealthy Days collected via the CDC Healthy Days scale. This scale asks the number of days in the past 30 days the person felt physically or mentally unwell. The summary index then estimates the number of recent days when a person's physical and mental health was good (or better) and is calculated by subtracting the number of unhealthy days from 30 days. The change in healthy days from baseline to twelve weeks by study arm will be reported.
Baseline and twelve weeks
Change in consumption of fruits and vegetables from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks
Dietary information using the Dietary Screener Questionnaire (DSQ) will be collected. The DSQ obtains information on the frequency of consumption of fruits and vegetables. These responses are then converted to cup equivalents per day using a scoring algorithm based on the NHANES 24-hour recall. Fruit and vegetable consumption from baseline to twelve weeks by study arm will be reported.
Baseline and twelve weeks
Change in consumption of added sugars from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks
Dietary information using the Dietary Screener Questionnaire (DSQ) will be collected. The DSQ obtains information on the frequency of consumption of added sugars. These responses are then converted to teaspoon equivalents per day using a scoring algorithm based on the NHANES 24-hour recall. Added sugars consumption (teaspoon equivalents per day) from baseline to twelve weeks by study arm will be reported.
Baseline and twelve weeks
Change in depressive symptoms from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks
The 8-item Patient Health Questionnaire (PHQ-8) will be used to evaluate depressive symptoms. The PHQ-8 score ranges from 0 to 24, with higher scores indicating higher levels of depression. The change in PHQ-8 scores from baseline to twelve weeks by study arm will be reported.
Baseline and twelve weeks
Change in diabetes self-efficacy from baseline to twelve weeks by study arm
Aikaikkuna: Baseline and twelve weeks
The 8-item Diabetes Self-Efficacy scale will be used to assess confidence in one's ability to manage numerous self-care behaviors. The scores ranges from 8 to 40, with higher scores indicating more confidence in self-managing their diabetes. The changes in the scores from baseline to twelve weeks by study arm will be reported.
