Overview

Unmet social needs and economic burden persist as key reasons why one-third of people with diabetes have poor disease control. The purpose of this study is to learn whether different tools and types of support may help people manage diabetes and related challenges. The study will compare several approaches to understand how they affect people's experiences and health over time. Completion of the study aims will lead to an optimized intervention to improve the health and social well-being of people with diabetes.

Participants will be randomly assigned to one or more interventions aimed at addressing social and financial needs and will complete multiple surveys over the course of a year. The study team will collect information about their blood pressure and HbA1c (blood glucose).

Findings will advance the field by determining the effectiveness of supportive interventions to address both social needs and diabetes self-care, and by informing protocols for the optimal sequencing of these strategies, a critical evidence gap in healthcare settings.
