Background: Hospital performance is tied to 30 day all-cause readmissions for patients discharged with heart failure (HF). Little is known of readmissions specifically for acute decompensated heart failure (ADHF), or whether readmission patterns differ for HF with preserved vs. reduced ejection fraction (HFpEF and HFrEF, respectively).
Methods: Since 2005, the ARIC Study has conducted hospital surveillance of ADHF within 4 US areas. ADHF was validated by physician review, with HFrEF defined as ejection fraction (EF) <50%. Cohort members were followed ≥2 years after hospital discharge, using the first ADHF hospitalization with EF data as the index. Hazard ratios of readmissions were analyzed with Cox regression, adjusted for age, race, and sex, and accounting for correlation between repeat readmissions.
Results: From 2005 – 2011, 875 cohort members survived at least 1 hospitalization for ADHF; a total of 684 (78%) had EF data. Most were white (61%), female (55%), with mean age 76 years; 369 (54%) were classified as HFrEF. Readmission rates for ADHF were highest within 30 days of discharge, and similar for HFpEF and HFrEF. However, HFrEF was associated with a 30% greater ADHF readmission rate at 6 months and 1 year, and a 20% greater readmission rate at 2 years. Mortality was similar for HFrEF and HFpEF at all observation periods.
Conclusions: Among hospitalized ADHF patients, HF type has little impact on 30 day readmission rates for ADHF. With longer follow up, ADHF readmission rates are greater with HFrEF.
