Background
Empagliflozin improves heart and kidney outcomes in type 2 diabetes, but trials may be too small to confirm whether benefits are similar across demographic and social groups. This study used Medicare data to examine real-world consistency of benefit.
Patients
Adults aged 65 years or older with type 2 diabetes in Medicare fee-for-service data, 2014-2020. Exclusions included type 1 diabetes, end-stage kidney disease, cancer, organ transplant, HIV/AIDS, nursing home admission, and inadequate prior enrollment.
Intervention
New initiation of empagliflozin.
Control
New initiation of dipeptidyl peptidase-4 inhibitors or glucagon-like peptide-1 receptor agonists.
Outcome
Modified major adverse cardiovascular events, heart failure hospitalization, and all-cause mortality.
Follow-up Period
Mean follow-up was about 10 months.
Results
| Comparison | Outcome | Hazard ratio | Absolute difference | Approximate NNT/year |
|---|---|---|---|---|
| Empagliflozin vs dipeptidyl peptidase-4 inhibitors | Major cardiovascular events | HR 0.77 (99.9% CI 0.69 to 0.85) | 10.3 fewer/1,000 person-years | 97 |
| Empagliflozin vs dipeptidyl peptidase-4 inhibitors | Heart failure hospitalization | HR 0.72 (99.9% CI 0.67 to 0.79) | 18.3 fewer/1,000 person-years | 55 |
| Empagliflozin vs dipeptidyl peptidase-4 inhibitors | Death | HR 0.66 (99.9% CI 0.57 to 0.76) | 8.6 fewer/1,000 person-years | 116 |
| Empagliflozin vs glucagon-like peptide-1 receptor agonists | Heart failure hospitalization | HR 0.88 (99.9% CI 0.81 to 0.95) | 6.9 fewer/1,000 person-years | 145 |
Benefits were similar by age, sex, race or ethnicity, insurance status, neighborhood deprivation, and baseline cardiovascular disease. Absolute benefits were larger in patients with existing cardiovascular disease. Major cardiovascular events and mortality were not significantly different versus glucagon-like peptide-1 receptor agonists.
Limitations
Observational claims data cannot prove causation, and unmeasured confounding may remain. Race and ethnicity were not self-reported. Results apply mainly to older Medicare fee-for-service patients. Some subgroups had limited event numbers.
Funding
Boehringer Ingelheim funded; employees coauthored, reportedly no design role.
Clinical Application
Consider empagliflozin for older adults with type 2 diabetes, especially with cardiovascular disease, when heart failure prevention is a priority.
