Abstract

AIMS:

The use of continuous subcutaneous insulin infusion (CSII) in type 1 diabetes (T1D) has increased in recent years. Sensor-augmented pump therapy (SAP) with low glucose suspend (LGS) (allowing temporary suspension of insulin delivery if blood glucose level falls below a pre-defined threshold level) provides additional benefits over CSII alone, but is associated with higher acquisition costs. Therefore, a cost-effectiveness analysis of SAP+LGS versus CSII in patients with T1D was performed.

METHODS:

Analyses were performed using the CORE Diabetes Model in two different patient cohorts in Denmark, one with hyperglycemia at baseline and one with increased risk for hypoglycemic events. Clinical input data were sourced from published literature. The analysis was performed over a lifetime time horizon from a societal perspective. Future costs and clinical outcomes were discounted at 3% per annum.

RESULTS:

In patients who were hyperglycemic at baseline the use of SAP+LGS versus CSII resulted in improved quality-adjusted life expectancy (12.44 versus 10.99 quality-adjusted life years [QALYs]) but higher mean lifetime costs (DKK 2,027,316 versus DKK 1,801,293) leading to an incremental cost-effectiveness ratio (ICER) of DKK 156,082 per QALY gained. For patients at increased risk for hypoglycemic events the ICER for SAP+LGS versus CSII was DKK 89,868 per QALY gained.

CONCLUSIONS:

The ICER for SAP+LGS versus CSII falls below commonly cited willingness-to-pay thresholds. Therefore, in Denmark, the use of SAP+LGS is likely to be considered cost-effective relative to CSII for patients with T1D who are either hyperglycemic, despite CSII use, or who experience frequent severe hypoglycemic events.
