An analysis of the cost-effectiveness of switching from biphasic human insulin 30, insulin glargine,or neutral protamine Hagedorn to biphasic insulin aspart 30 in people with type 2 diabetes

Abstract

Aims:

The aim of this analysis was to assess the cost-effectiveness of switching from biphasic human insulin 30 (BHI), insulin glargine (IGlar), or neutral protamine Hagedorn (NPH) insulin (all?±?oral glucose-lowering drugs OGLDs]) to biphasic insulin aspart 30 (BIAsp 30) in people with type 2 diabetes in India, Indonesia, and Saudi Arabia.

Methods:

The IMS CORE Diabetes Model was used to determine the clinical outcome, costs, and cost-effectiveness of switching from treatment with BHI, IGlar, or NPH to BIAsp 30 over a 30-year time horizon. A 1-year analysis was also performed based on quality-of-life data and treatment costs. Incremental cost-effectiveness ratios (ICERs) were expressed as a fraction of gross domestic product (GDP) per capita, and cost-effectiveness was defined as ICER <3-times GDP per capita.

Results:

Switching treatment from BHI, IGlar, or NPH to BIAsp 30 was associated with an increase in life expectancy of >0.7 years, reduction in all diabetes-related complications, and was considered as cost-effective or highly cost-effective in India, Indonesia, and Saudi Arabia (BHI to BIAsp 30, 0.26 in India, 1.25 in Indonesia, 0.01 in Saudi Arabia; IGlar to BIAsp 30, ?0.68 in India, ?0.21 in Saudi Arabia; NPH to BIAsp 30, 0.15 in India, ?0.07 in Saudi Arabia; GDP per head per annum/quality-adjusted life-year). Cost-effectiveness was maintained in the 1-year analyses.

Conclusions:

Switching from treatment with BHI, IGlar, or NPH to BIAsp 30 (all?±?OGLDs) was found to be cost-effective in India, Indonesia, and Saudi Arabia, both in the long and short term.
