INTRODUCTION

Utility values are used in health economic modeling analyses of type 2 diabetes (T2D) to quantify the effect of acute and long-term complications on quality of life (QoL). For accurate modeling projections, it is important that the utility values used are up to date, accurate and representative of the simulated model cohort.

METHODS

A literature review was performed to identify utility values for health states representing acute and chronic T2D-related complications including cardiovascular complications, stroke, renal disease, ophthalmic complications, neuropathy, diabetic foot, amputation and hypoglycemia. Searches were performed using the PubMed, Embase and Cochrane Library databases and limited to articles published since 2010. Supplementary searches were performed to identify data published at congresses in 2019-2023.

RESULTS

A total of 54 articles were identified that reported utility values for T2D-related complications. The most frequently used elicitation method/instrument was the EQ-5D (n = 42 studies) followed by the Short Form-6 dimensions (n = 6), time tradeoff (n = 5), the Health Utilities Index Mark 2 or Mark 3 (n = 2), 15D (n = 1), visual analog scale (n = 1) and standard gamble (n = 1). Stroke and amputation were consistently associated with the largest decrements in QoL. There is a lack of published data that distinguishes between severity of several complications including renal disease, retinopathy and neuropathy.

CONCLUSIONS

Diabetes-related complications can have a profound impact on QoL; therefore, it is important that these are captured accurately and appropriately in health economic models. Recently published utility values for diabetes-related complications that can be used to inform health economic models are summarized here.
