Abstract Author Manuscript

BACKGROUND—Heart failure is the leading cause for 30-day all-cause readmission. We examined the impact of 30-day all-cause readmission on long-term outcomes and cost in a propensity score matched study of hospitalized patients with heart failure.

METHODS—Of the 7578 Medicare beneficiaries discharged with a primary diagnosis of heart failure from 106 Alabama hospitals (1998–2001) and alive at 30-day post-discharge, 1519 had 30day all-cause readmissions. Using propensity scores for 30-day all-cause readmission, we assembled a matched cohort of 1516 pairs of patients with and without 30-day all-cause readmissions, balanced on 34 baseline characteristics (mean age 75 years, 56% women, 24% African American).

RESULTS—During 2-12 months of follow-up after discharge from index hospitalization, allcause mortality occurred in 41% and 27% of matched patients with and without 30-day all-cause readmission, respectively (hazard ratio {HR}, 1.68; 95% confidence interval {CI}, 1.48–1.90; p
