Abstract
The efficacy of real-time continuous glucose monitoring (rt-CGM) in adjusting insulin therapy in long-term care facilities (LTCF) has not been evaluated. Accordingly, we randomized 100 insulin-treated subjects with T2D in LTCF. All subjects underwent point-of-care (POC) capillary glucose testing before meals and bedtime. Patients in the standard of care (POC group) wore a blinded Dexcom G6 CGM with treatment adjusted based on POC results; while in the rt-CGM group (Dexcom G6), treatment adjustment was based on daily CGM profile. Treatment adjustment was performed by the LTC medical team, with a target glucose of 140-180 mg/dL, and a duration of intervention up to 60 days. Primary endpoint was difference between groups in time in range (TIR, 70-180 mg/dL). Results: There were no significant differences in TIR (53.38%±30.16 vs 48.81%±28.03, p=0.40), mean daily glucose (185±44 vs 191 ±47 mg/dL, p=0.72), patients with % CGM values <54 mg/dL (0.23±0.8% vs 0.56±2.2 %, p=0.88), with a trend in reducing time below range (TBR <70 mg/dL) (0.83±2.6 % vs 1.18±3.5%, p= 0.51), between CGM and POC group. Conclusion: The results of this pilot randomized study indicate that the use of Dexcom G6 rtCGM is safe and effective in guiding diabetes therapy in long-term care facilities, resulting in a similar improvement in glycemic control (TIR) without differences in hypoglycemia.
