A randomized controlled trial to evaluate an educational strategy involving community health volunteers in improving self-care in patients with chronic heart failure: Rationale, design and methodology

© 2014, Siabani et al.; licensee Springer. Background: Chronic heart failure (CHF) is an increasingly important health problem worldwide. Effective self-care can improve the outcomes and quality of life in patients with CHF. Acknowledging the important role of educational interventions for improving self-care, we sought to assess a new educational strategy involving community health volunteers (CHVs) that could reduce the cost and, hypothetically, increase the effectiveness of self-care education in patients with CHF.Methods/Design: In this ongoing three-arm controlled trial, approved by two human research ethics committees in Australia and Iran, 231 patients with CHF registered at a referral cardiovascular hospital in Iran were randomly allocated into three groups -trained by community health volunteers at patients’ homes, rained by formal health professionals at hospital; and a control group with no formal educational exposure. Data obtained through interviewing participants and using the Persian self-care of CHF index (pSCHFI) before and two months after interventions will be analysed using SAS and SPSS.Discussion: The results of this study may help health service systems, especially in countries with limited resources, make use of community volunteers to teach patients with CHF to develop self-care behaviors and skills, reducing the cost of care and improving CHF outcomes. Also, this home-based educational strategy using face-to-face training, if successful, may provide psychosocial supports for patients suffering from chronic illnesses.Trial registration number: ACTRN12614000788673(Australian New Zealand Clinical Trials Registry)
