BACKGROUND: Little is known about the relationship between self-care in heart failure (HF) and outcomes like health status. The purpose of this study was to describe the relationship between HF self-care and Short Form-36 (SF-36) health status domains. METHODS AND RESULTS: A secondary analysis of cross-sectional data collected on 400 HF patients living in southern Thailand was completed using bivariate comparisons and hierarchical multiple regression modeling. Thai population norm-based SF-36 scores and Self-Care of Heart Failure Index (SCHFI) scores were used in the analysis. The sample was in older adulthood (65.7 +/- 13.8 years), a slight majority of subjects were male (52%); the majority of subjects (62%) had class III or IV HF. Each health domain was low in this sample compared to the general population. SCHFI maintenance and confidence scores were correlated significantly with each health status domain. SCHFI scores explained a significant amount of variance all domains, both in bivariate and multivariate models, except social functioning. In multivariate models, higher levels of self-care were associated with better health in certain domains, but only when both SCFHI management and confidence were high. CONCLUSION: Improving HF self-care may be a mechanism through which future interventions can improve health in this population.
