Abstract 14207: Racial Differences in the Incidence and Outcomes of Heart Failure in Commercially Insured Patients
Background: Epidemiologic studies have demonstrated that the incidence of heart failure varies by race and ethnicity, with the highest incidence occurring in blacks. However, whether these racial and ethnic variations extend to commercially insured populations and whether differences in early outcomes after diagnosis exist requires further exploration.
Methods: We utilized administrative claims data from a large U.S. commercial insurance database to retrospectively identify privately insured and Medicare Advantage patients who were diagnosed with heart failure between 2006 and 2014. Published claims-based algorithms were used to identify patients with incident HF and categorize reasons for hospitalization after diagnosis.
Results: Among 148,827 patients with incident heart failure (mean age 72.2 years, 51% women), 70% were white, 15% black, 6% Hispanic, 3% Asian and 6% had unknown race/ ethnicity. The incidence of heart failure during the study period was 3.7 per 1000 person-years and was highest among blacks, followed by whites, Hispanics and Asians (9.9, 3.6, 2.5, and 2.0 per 1000 person-years, respectively). In total, 37% of patients were hospitalized at least once in the first year after diagnosis for a total of 93,358 hospitalizations. HF was the most common reason for hospitalization (13% of all hospitalizations), followed by arrhythmia (5%), sepsis (5%), pneumonia (4%), COPD (3%) and acute renal failure (3%). Reasons for hospitalization were similar across racial and ethnic groups. The rate of hospitalizations was highest the first month after diagnosis and then gradually declined. Black patients had the highest rates of hospitalization, while Asians had the lowest (Figure).
Conclusions: Even among a commercially insured population that likely have fewer barriers to care, black patients had a higher incidence of HF and higher rates of hospitalization after initial diagnosis compared with other racial and ethnic groups.
