This randomized controlled trial will investigate whether use of continuous glucose monitoring (CGM) vs. usual care with self-monitored blood glucose 1) enhances glycemic control, 2) reduces hypoglycemia risk, and 3) improves quality of life, diabetes distress, and fear of hypoglycemia in hemodialysis patients with diabetes mellitus.
This is a parallel, two-arm randomized controlled trial comparing real-time CGM using Dexcom G6 devices vs. usual care (self-monitored blood glucose 4-times/day) among 122 in-center hemodialysis patients with diabetes mellitus over a 12-week period. Our primary objective will be to determine the effects of CGM vs. usual care on glycemic control, defined by percent (%) of time in target glucose range (70-180 mg/dl). Our main and exploratory secondary objectives will be to determine the effects of CGM on CGM-indices of hypoglycemia, blood-based glycemic markers (HbA1c, glycated albumin, fructosamine), and patient-reported outcomes (health-related quality of life, diabetes distress, hypoglycemia fear). We will also evaluate feasibility endpoints by measuring CGM compliance during the intervention period and success/ease of implementing CGM training sessions among patients.
