Background and Aims: Sensor-augmented pump therapy (SAP) combines continuous glucose monitoring with continuous subcutaneous insulin infusion (CSII). SAP is costlier than CSII but provides additional clinical benefits relative to CSII alone. A long-term cost-effectiveness analysis was performed to determine whether SAP is cost-effective relative to CSII in patients with type 1 diabetes (T1D) in Turkey. Methods: Analyses were performed in two different patient cohorts, one with poor glycemic control at baseline (mean glycated hemoglobin 9.0% [75 mmol/mol]) and a second cohort considered to be at increased risk of hypoglycemic events. Clinical input data and direct medical costs were sourced from published literature. The analysis was performed from a third-party payer perspective over patient lifetimes and future costs and clinical outcomes were discounted at 3.5% per annum. Results: In both patient cohorts, SAP was associated with a gain in quality-adjusted life expectancy but higher costs relative to CSII (incremental gain of 1.40 quality-adjusted life years [QALYs] in patients with poor baseline glycemic control and 1.73 QALYs in patients at increased risk of hypoglycemic events). Incremental cost-effectiveness ratios for SAP versus CSII were TRY 76,971 (EUR 11,612) per QALY gained for patients with poor baseline glycemic control and TRY 69,534 (EUR 10,490) per QALY gained for patients at increased risk for hypoglycemia. Conclusions: SAP is associated with improved long-term clinical outcomes versus CSII, and in Turkey, SAP is likely to represent good value for money compared with CSII in T1D patients with poor glycemic control and/or with frequent severe hypoglycemic events.
