Abstract
Background: We conducted a model-based economic analysis of sodium-glucose cotransporter-2 inhibitors (SGLT2is) versus dipeptidyl peptidase-4 inhibitors (DPP4is) in type 2 diabetes (T2D) patients with and without established cardiovascular disease (CVD) using 10-year real-world data. Methods: A Markov model was utilized to estimate healthcare costs and quality-adjusted life-years (QALYs) over a 10-year simulation time horizon from a healthcare sector perspective, with both costs and QALYs discounted at 3% annually. Model inputs were derived from analyses of Taiwan’s National Health Insurance Research Database or published studies of Taiwanese populations. The primary outcome measure was the incremental cost-effectiveness ratios (ICERs). Incorporated with our study findings, a structured systematic review was conducted to synthesize updated evidence on the cost-effectiveness of SGLT2is versus DPP4is. Results: Over 10 years, use of SGLT2is versus DPP4is yielded ICERs of $3,244 and $4,186 per QALY gained for T2D patients with and without established CVD, respectively. Results were robust across a series of sensitivity and scenario analyses, showing ICERs between $-1,074 (cost-saving) and $8,467 per QALY gained for T2D patients with established CVD and between $369 and $37,122 per QALY gained for T2D patients without established CVD. A systematic review revealed a cost-effective or even cost-saving profile of using SGLT2is for T2D treatment. Conclusions: Use of SGLT2is versus DPP4is was highly cost-effective for T2D patients regardless of patients’ CVD history in real-world clinical practice. Our results extend current evidence by demonstrating SGLT2is as an economically rational alternative over DPP4is for T2D treatment in routine care. Future research is warranted to explore heterogenous economic benefits of SGLT2is given diverse patient characteristics in clinical settings.
