The cost-effectiveness of continuous glucose monitoring in type 1 diabetes.

Objective: Continuous glucose monitoring (CGM) has been found to improve glucose control in type 1 diabetic patients. We estimated the cost-effectiveness of CGM versus standard glucose monitoring in type 1 diabetes. RESEARCH DESIGN AND METHODS This societal cost-effectiveness analysis (CEA) was conducted in trial populations in which CGM has produced a significant glycemic benefit (A1C >or=7.0% in a cohort of adults aged >or=25 years and A1C ResultsDuring the trials, CGM patients experienced an immediate quality-of-life benefit (A1C >or=7.0% cohort: 0.70 quality-adjusted life-weeks [QALWs], P = 0.49; A1C or=7.0% cohort, CGM was projected to reduce the lifetime probability of microvascular complications; the average gain in QALYs was 0.60. The incremental cost-effectiveness ratio (ICER) was $98,679/QALY (95% CI -60,000 [fourth quadrant] to -87,000 [second quadrant]). For the A1C ConclusionsLong-term projections indicate that CGM is cost-effective among type 1 diabetic patients at the $100,000/QALY threshold, although considerable uncertainty surrounds these estimates.
