Introduction: Cardiovascular disease (CVD) affects approximately 30% of patients with diabetes mellitus type 2 (T2D) and leads to increased morbidity, decreased survival and increased healthcare utilization. The aim of this study was to estimate the impact of treating these patients with the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin on survival and healthcare utilization.
Methods: Actual survival and healthcare utilization data from a 5-year retrospective cohort study on patients with T2D and CVD in the Region of Östergötland, Sweden were used as a starting point. Actual data were adjusted in accordance with risk reductions for mortality and CV events related to empagliflozin treatment as reported in the EMPA-REG OUTCOME study.
Results: Applying the risk reductions related to empagliflozin treatment on the cohort of patients with T2D and CVD in Östergötland resulted in an increase in 5-year survival of 96 days per patient and reduced costs for healthcare and drugs other than empagliflozin. Including the cost of empagliflozin, treatment led to an increased net cost per patient of approximately SEK 18,000 over 5 years.
Conclusion: Empagliflozin treatment would reduce mortality and healthcare utilization in the patient group. The treatment strategy should be considered cost-effective, supporting a broad implementation of empagliflozin for patients with T2D and established CVD, in line with current national and international guidelines.
