Healthcare Resource Utilization and Associated Costs in New Users of Empagliflozin versus DPP-4 Inhibitors and GLP-1 Agonists: A Comparative Analysis Based on Retrospective Real-World Data from German Sickness Funds.

PURPOSE

Achieving good glycemic control in type 2 diabetes (T2DM) may require individualized pharmacological approaches. We aimed to compare direct healthcare costs in patients treated with empagliflozin (EMPA) compared to dipeptidyl peptidase-4 inhibitors (DPP-4i) or glucagon-like peptide-1 receptor agonists (GLP-1-RA).

PATIENTS AND METHODS

This German claims data study included continuously insured persons with at least two outpatient diagnoses and/or one inpatient diagnosis of T2DM if they started EMPA, DPP-4i, or GLP-1-RA in 2015-2018. Healthcare costs were assessed from therapy initiation until the end of data availability, death, or therapy discontinuation and compared among propensity score-matched cohorts.

RESULTS

Of 24,465 patients included, 3285 received EMPA, 19,443 DPP-4i, and 1747 GLP-1-RA. Matched cohorts were balanced on baseline characteristics (EMPA versus DPP-4i: n/n = 3100/3100 and EMPA versus GLP-1-RA: n/n = 1346/1346). Mean total costs after start of DPP-4i were €7009 (95%-CI: 6573-7444) versus €4274 (3982-4566) for EMPA. Costs associated with GLP-1-RA treatment were also significantly higher compared with EMPA (€6851 [6183-7518] versus €4895 [4345-5445]).

CONCLUSION

Although the individual clinical patient profile and physician assessment are paramount in treatment decisions, substantial differences in the economic impact of different antidiabetic therapies should be considered.
