Readmission to acute care facilities is a frequent and costly problem among older adults with congestive heart failure (CHF). The study reported in this article tested the hypothesis that adequate home care, operationalized as patient-perceived adequacy of formal and informal assistance, is associated with lower readmission to acute care facilities. The study followed 253 elderly (age 65 and older) Medicare patients discharged to their homes after hospitalization for CHF, through structured telephone interviews at two, six, 10, and 14 weeks postdischarge. Study findings point to the importance of home care in reducing the high risk of readmission among elderly patients. The findings raise implications for practice, policy, and research.
