Community pharmacy-led diabetes management using continuous glucose monitoring for suboptimally controlled type 2 diabetes: A pilot feasibility study

by Kyung-In Joung, Ji Won Hwang, So Young Seo, Kyeong Han Back, Yong Geun Jeon, Kwang Joon Kim Many adults with type 2 diabetes mellitus (T2DM) managed without insulin continue to experience suboptimally controlled glycemia. This 12-week, single-arm pilot feasibility study was conducted across 11 community pharmacies in South Korea to evaluate the feasibility and clinical effectiveness of a community pharmacy-led diabetes management model using continuous glucose monitoring (CGM) integrated with digital health platforms.

Thirty adults with suboptimally controlled T2DM (HbA1c ≥ 6.5%) on stable oral regimens were enrolled. The intervention combined medication, exercise, and nutrition counseling using CGM (Abbott LibreView®) integrated with the national Personal Health Record system.

The primary composite endpoint was defined as achieving all three at week 12: (1) HbA1c ≤ 7.0%, (2) meaningful HbA1c reduction (≥0.5% absolute or ≥10% relative), and (3) time in range (TIR, 70–180 mg/dL) >70%. Results showed that all 30 participants completed the program, with 36.7% achieving the primary composite endpoint.
