Objective:Type 2 diabetes is characterised by progressive failure of pancreatic beta-cell function against a background of insulin resistance. Multifactorial interventions, including intensive glycaemic and blood pressure control, reduce the risk of onset and progression of complications. However, current management of type 2 diabetes focuses on treatment of signs and symptoms of disease instead of targeting underlying causes. A number of newer pharmacological interventions, including thiazolidinediones and glucagon-like peptides, have shown early promise in preserving pancreatic beta-cell function. The aim of this study was to investigate the impact of stabilising beta-cell function on long-term outcomes in patients with type 2 diabetes. Methods: The CORE Diabetes Model was used to project life expectancy (LE), quality-adjusted LE (QALE) and total lifetime complication costs (TC) for a cohort of newly-diagnosed patients with type 2 diabetes, either with a typical increase of HbA(1c) over time as observed in the UKPDS, or assuming stabilisation of HbA(1c) after diagnosis with a hypothetical new treatment, representing beta-cell function stabilisation. Costs due to diabetes-related complications (from a US third-party payer perspective), were discounted at 3% annually. Both non-discounted and discounted (at 3% annually) LE and QALE were calculated. Sensitivity analyses were performed to test the robustness of results. Results: Over a time period of 50 years, in a cohort with no increase of HbA(1c) over time, LE and QALE were improved by mean (SD) 1.02 (0.36) and 0.96 (0.25) years, and total costs of complications were reduced by $6,377 (2,568) per patient compared to the cohort with a typical increase in HbA(1c) over time. Results were robust under a wide range of plausible assumptions. Conclusions: New interventions that stabilise pancreatic beta-cell function may have an important impact on length and quality of life, and lead to reduced costs of complications in patients with type 2 diabetes.
