Objective: In recent years, a growing number of people with type 1 diabetes have access to real-time continuous glucose monitoring (rtCGM). Long-term benefits of rtCGM are unclear due to lack of large studies of long duration. We evaluated whether real-world rtCGM-use up to 24 months offered benefits, in particular to those living with impaired awareness of hypoglycemia (IAH). Research Design and Methods: This 24-month, prospective, observational, cohort study followed 441 adults with insulin pumps receiving full reimbursement for rtCGM. Forty-two percent had IAH. Primary endpoint was evolution of HbA1c, with secondary endpoints change in acute hypoglycemia complications, diabetes-related work absenteeism, and quality of life (QOL) scores. Additionally, we evaluated if people could achieve glycemic consensus targets during follow-up. Results: After 24 months, HbA1c remained significantly lower compared to baseline (7.64% [60 mmol/mol] vs 7.37% [57 mmol/mol], p1c Conclusion: Use of rtCGM led to sustained improvements in hypoglycemia-related glucose control over 24 months. Lower fear of hypoglycemia, less acute hypoglycemia-related events and diabetes-related days off work were observed, particularly in those with IAH. |
