Advanced Heart Failure Characteristics and Outcomes in Commercially Insured U.S. Adults.

BACKGROUND

The characteristics and outcomes of patients with advanced heart failure (HF) have been poorly defined due to challenges in applying the complex advanced HF definition broadly to populations.

OBJECTIVES

In this study, the authors sought to apply a validated advanced HF algorithm to a large U.S. administrative claims database and describe the population and use of advanced HF therapies.

METHODS

This study included adults with advanced HF identified in the OptumLabs Data Warehouse from 2009 to 2019. The algorithm for advanced HF required 2 hospitalizations for HF plus 1 additional sign of advanced HF in a 12-month period. The association of baseline characteristics with mortality was examined with the use of Cox proportional hazards models. Associations of patient characteristics with advanced therapies were estimated with the use of cause-specific Cox proportional hazard models.

RESULTS

In 60,197 patients identified with advanced HF, the mean age was 73 years, 51.5% were men, and 64.3% were non-Hispanic White, 1.9% Asian, 21.2% Black, and 8.2% Hispanic. The median survival with advanced HF was 2.0 years (IQR: 0.4-5.5 years). Differences in mortality and use of advanced therapies by age, sex, and race/ethnicity were observed. Adjusted mortality was higher in patients who were older, male, non-Hispanic White, and from rural areas (P < 0.05 for all). Advanced therapies were used less in older patients and women (P < 0.05 for both). Black patients were more likely to be treated with a left ventricular assist device (P = 0.010) but less likely to receive a heart transplant compared with White patients (P = 0.034).

CONCLUSIONS

In U.S. adults with advanced HF, variation in outcomes and use of advanced therapies exist by age, sex, and race/ethnicity.
