Details and patient eligibility

About

The investigators aim is to conduct a randomized clinical trial in an underserved population who are either uninsured or on Medicaid and taking at least one injection of insulin daily. The investigators believe that this study will lead to considerable alleviation of health disparities and provide better care for an underserved population. This will be a pilot study to evaluate the feasibility of such a trial in this population before doing a larger multicenter trial.

Full description

This study is a randomized open label trial with study participants being randomized to either a continuous glucose monitoring group (intervention) or a self-monitoring group (control) after a period of two-week run-in and followed for 6 months. All participants regardless of assignment will be provided diabetes education. Participants randomized to the self-monitoring group will be given an opportunity to wear the CGM sensor for 3 months at the conclusion of the 6-month follow-up as an optional follow-up.
