Abstract

Background: We examined the effect of a home-based intervention (HBI) on readmission and death among 'high-risk' patients with congestive heart failure discharged home from acute hospital care. Methods: Hospitalized patients with congestive heart failure and impaired systolic function, intolerance to exercise, and a history of 1 or more hospital admissions for acute heart failure were randomized to either usual care (n=48) or HBI at 1 week after discharge (n=49). Home-based intervention comprised a single home visit (by a nurse and pharmacist) to optimize medication management, identify early clinical deterioration, and intensify medical follow-up and caregiver vigilance as appropriate. The primary end point of the study was frequency of unplanned readmissions plus out-of-hospital deaths within 6 months of discharge. Secondary end points included duration of hospital stay and overall mortality. Results: During follow-up, patients in the HBI group had fewer unplanned readmissions (36 vs 63; P=.03) and fewer out-of-hospital deaths (1 vs 5; P=.11): 0.8±0.9 vs 1.4±1.8 (mean ± SD) events per patient assigned to HBI and usual care, respectively (P=.03). Patients in the HBI group also had fewer days of hospitalization (261 vs 452; P=.05) and fewer total deaths (6 vs 12; P=.11). Patients assigned to usual care were more likely to experience 3 or more readmissions for acute heart failure (P=.02). Predictors of unplanned readmission were (1) 14 days or more of unplanned readmission during the 6 months before study entry (odds ratio [OR], 5.2; 95% confidence interval [CI], 1.8-16.2), (2) previous admission for acute myocardial ischemia (OR, 3.3; 95% CI, 1.2-9.1), and (3) an albumin plasma concentration of 38 g/L or less (OR, 2.4; 95% CI, 1.2-6.0). Home-based intervention was also associated with a trend toward reduced risk of unplanned readmission (OR, 0.4; 95% CI, 0.2-1.1). Conclusion: Among a cohort of high-risk patients with congestive heart failure, HBI was associated with reduced frequency of unplanned readmissions plus out-of-hospital deaths within 6 months of discharge from the hospital.
