Continuous glucose monitoring (CGM) in patients with type 1 diabetes is effective in preventing some hypoglycemic episodes but has not been studied thoroughly in older adults. In this comparative study, 203 older adults (median age, 68) with type 1 diabetes (median duration, 37 years) and glycosylated hemoglobin (HbA1c) <10% were randomized to CGM or routine blood glucose monitoring at least four times daily. Routine monitoring patients had masked continuous glucose monitors placed for 1 week at 7, 15, and 25 weeks.
At 26 weeks, the CGM group had a significant reduction in median time daily with blood glucose concentration <70 mg/dL (from 73 to 39 minutes) compared with no significant change in the routine monitoring group (68 to 70 minutes)…
