Improving blood sugar control in type 1 diabetes using team care, technology, education and peer support

Official title: Glycemic Improvement With Team, Technology, Education and Peer Resources in Type 1 Diabetes-GLITTER Study

Run by Second Xiangya Hospital of Central South University · NCT07097805 · Data updated 2026-11-12

This program will try whether combining a care team, diabetes technologies (like CGMs and pumps), structured education, and peer support helps people with type 1 diabetes manage their blood sugar better.

Is this trial a fit for you?

Likely a good fit

People of any age with a clinical diagnosis of type 1 diabetes who are on insulin therapy or meet diagnostic criteria such as early onset, diabetic ketoacidosis at presentation, low C‑peptide, or positive islet autoantibodies are eligible.

Probably not a fit

Patients who already have excellent glycemic control with current care, those unable or unwilling to attend participating centers or engage in education/peer activities, and individuals with pancreas or islet transplants are unlikely to gain additional benefit.

What this trial studies

The GLITTER program implements a four-in-one management model that combines multidisciplinary clinical teams, structured education, peer support groups, and access to diabetes technologies. It is a multicenter, prospective cohort across several major hospitals in China and follows patients longitudinally to track metabolic control. Education is delivered through specialty clinics and local clinicians, while technology access (CGM and pumps) is offered but not mandated, and peer support is organized via patient communication groups. The aim is population-wide coverage and whole-disease-course management to increase the rate of patients reaching glycemic targets.

Why it matters

Potential benefit: If successful, this integrated approach could increase the proportion of people with type 1 diabetes who reach and maintain target blood glucose levels and reduce glycemic variability.

How similar studies have gone: Previous research shows that structured education, peer support, and diabetes technologies can each improve outcomes, but combining all four components in a single integrated program is less well tested.
