Texts for Diabetes Control Among Homeless Persons

This mixed method study includes a Randomized Controlled Trial (RCT) and qualitative methods to assess the impact of a SMS text strategy in diabetes control among persons who experience homelessness.

Diabetes mellitus (DM) is common among persons experiencing homelessness (PEH), often inadequately managed, and carries significant costs. SMS strategies for DM have not been tested among PEH despite the accessibility of mobile phones. This study uses a SMS strategy to offer better communication, education, and information management; improve outreach; facilitate care coordination; explore barriers to care; and support behavior changes. This mixed-methods (RCT and qualitative) study will be implemented in shelter-clinics in New York City in collaboration with community organizations, allowing for sustainability and scalability. Aim 1 will evaluate the efficacy of a 6-month SMS program for DM management versus an attention control on changes in HbA1c and adherence to DM self-care activities, medications, and appointments at 9 months in adult PEH with uncontrolled DM (n=100). Outcomes will be measured at 0, 3, 6, \&9 months. Aim 2 will assess patients' and providers' attitudes, acceptability, and experience of the program through semi-structured interviews with PEH and providers.
