Continuous subcutaneous insulin infusion; multiple daily injections; cost-effectiveness; type 1 diabetes
In Qingdao, China, continuous subcutaneous insulin infusion (CSII) therapy has been found to be more cost-effective than multiple daily injections (MDI) therapy for children and adolescent patients with type 1 diabetes (T1D). It should be considered as the preferred treatment modality.
Objective To evaluate the health economics of using continuous subcutaneous insulin infusion (CSII) therapy versus multiple daily injections (MDI) therapy in children and adolescent patients with type 1 diabetes (T1D) in Qingdao, China. Methods A long-term cost-effectiveness analysis was conducted using the IQVIA Core Diabetes Model (CDM). The baseline characteristics of the simulated cohorts were obtained from 213 pediatric T1D patients who received care with CSII(104 cases) or MDI(109 cases) in Qingdao from 1 January 2015 to 31 March 2019. In the essential case, the expenditure of the complications and treatment of the disease with both therapies were evaluated in Chinese currency from the perspective of healthcare system. In a secondary analysis, the model used a 70-year time horizon, and a discount rate of 5% was applied to all future health outcomes and costs. A one-way sensitivity analysis was conducted on delta HbA1c, different prices of insulin pump, price of each upgrade cycle rates and different discount rates. Uncertainty was also evaluated by the probability sensitivity analysis and scenario analysis. Results In the base-case analysis, the lifetime total costs were lower for CSII group at yen 630,871 per patient compared with yen 672,672 for MDI group. The quality-adjusted life years (QALYs) gained were 11.612 and 11.197 for patients treated with CSII group and MDI group, respectively. The CSII group was cost-saving compared to MDI group. The feasibility of CSII group being cost-effective was 100% under the threshold of 3 times per capita GDP of China in 2019 ( yen 212,676) which was indicated from the probabilistic sensitivity analysis. Regarding scenario analysis, the ICER of the CSII group compared to MDI was between -151,583 and 153,366 RMB/QALYs, which is cost-effective. Conclusions This economic evaluation compared CSII therapy versus MDI therapy for T1D children and adolescent patients in China and findings indicate that CSII should be considered a preferred treatment modality to MDI.
