Abstract
BACKGROUND AND AIMS: Sensor-augmented pump therapy (SAP) combines real time continuous glucose monitoring (CGM) with Continuous Subcutaneous Insulin Infusion (CSII) and provides additional benefits beyond those provided by CSII alone. SAP with automated insulin suspension provides early warning of the onset of hyperglycemia and hypoglycemia and has the functionality to suspend insulin delivery if sensor glucose levels are predicted to fall below a predefined threshold. Aim of this study was to assess the cost-effectiveness of SAP with automated insulin suspension versus CSII alone in type 1 diabetes. METHODS AND RESULTS: Cost-effectiveness analysis was performed using the CORE Diabetes Model. The analysis was performed in two different cohorts: one with high baseline HbA1c and one at elevated risk for hypoglycemic events. Clinical input data were sourced from published data. The analysis was conducted from a societal perspective over a lifetime time horizon; costs and clinical outcomes were discounted at 3% per year. In patients with poor glycemic control, SAP with automated insulin suspension resulted in improved discounted quality-adjusted life expectancy (QALY) versus CSII (12.44 QALYs vs. 10.99 QALYs) but higher mean total lifetime costs (€324,991 vs. €259,852), resulting in an incremental cost effectiveness ratio (ICER) of €44,982 per QALY gained. In patients at elevated risk for hypoglycemia, the ICER was €33,692 per QALY gained for SAP versus CSII. CONCLUSION: In Italy, the use of SAP with automated insulin suspension is associated with projected improvements in outcomes as compared to CSII. These benefits translate into an ICER usually considered as good value for money, particularly in patients at elevated risk of hypoglycemia.
