CGM-Assisted Community Management for Type 2 Diabetes

Sponsor: Peking University

Summary

This non-randomised, parallel-group pragmatic study used a type 2 effectiveness-implementation hybrid design to evaluate a continuous glucose monitoring (CGM)-assisted community management strategy for adults with type 2 diabetes in Yinzhou District, Ningbo, China. The study was conducted at two community health institutions that routinely provided chronic disease management services. Group assignment was not randomised and involved participant self-selection. A total of 599 participants were enrolled, including 292 participants in the CGM-assisted management group and 307 participants in the usual-care group. The intervention was a multicomponent CGM-assisted management strategy rather than the use of a CGM device alone. It included a CGM device with a mobile application and clinician-facing data platform, structured training for community providers, one-to-one patient education, a standardised workflow for interpreting glucose patterns and providing dietary, physical-activity, and medication-management advice, and three scheduled 14-day CGM wear periods at weeks 0, 8, and 16. After each wear period, participants returned for clinician review and management adjustment. Participants in the usual-care group continued routine community diabetes management, including self-monitoring of blood glucose. The primary effectiveness outcome was the between-group difference in HbA1c at 24 weeks. Secondary effectiveness outcomes included clinically meaningful HbA1c reductions and target attainment, fasting plasma glucose, body-mass index, lipid measures, behavioural changes, and changes in glucose-lowering medication management. CGM-derived glycaemic metrics were assessed descriptively within the intervention group across the three wear periods. Implementation outcomes were evaluated using the RE-AIM framework and included study-period reach, institutional and provider adoption, intervention delivery fidelity, participant completion, provider-perspective delivery cost, willingness to continue CGM use, participant satisfaction, and continuation of CGM-related services at the participating sites. The study aimed to assess both the effectiveness of CGM-assisted management and its implementation within routine Chinese community diabetes care.
