Persistent Performance Improvement Using Team Resources and Continuous Glucose Monitoring in Patients With Poorly Controlled Type 2 Diabetes.

Objective: The purpose of this study was to assess the impact of an interdisciplinary diabetes care team approach using continuous glucose monitoring (CGM) on glycemic outcomes in a population of adults with type 2 diabetes with suboptimal glycemic control.

Research design and methods: This 6-month, longitudinal observational study was conducted at the outpatient endocrinology clinic of Carilion Clinic in Roanoke, VA. The intervention included use of CGM and weekly interactions either virtually or by telephone by one of the team members. The primary outcomes were changes in A1C, average glucose, and glycemic time in range (TIR; 70-180 mg/dL) over the 6-month observation period. Changes in diabetes medications were also assessed.

Results: Twenty-one adults with type 2 diabetes and a baseline A1C >9% were included in the analysis. At 6 months, A1C levels decreased from 11.3 to 7.6%, average glucose decreased from 212.8 to 159.5 mg/dL, and TIR increased from 44.5 to 67.7%.

Conclusion: These results suggest that an interdisciplinary team approach in combination with CGM and frequent interaction is effective in improving glycemic outcomes in a high-risk population. Studies of longer duration are needed to further elucidate the efficacy of this intervention.
