The effects and cost-effectiveness of an empowerment-based self-care program in patients with chronic heart failure: A study protocol.

Aim This study aims to evaluate the effects of a 12-week empowerment-based self-care programme on the cognitive, psychological and behavioural aspects of self-care, health-related quality of life and unplanned hospital service use of chronic heart failure patients and to estimate its cost-effectiveness in reducing unplanned service use. Study design Randomized controlled trial with cost-effectiveness analysis. Methods The study will recruit 236 community-dwelling Chinese patients with chronic heart failure from regional hospitals in Hong Kong. Patients will be randomized in blocks to attend either the 12-week empowerment-based self-care programme or a didactic education programme. Central to the empowerment-based model is that the patients are the primary decision makers in self-care and act autonomously to manage the disease. Collaborative approach and interactive teaching strategies are used to optimize patients' engagement and knowledge translation to real-life practice. Outcome evaluation on self-care maintenance and management, symptom perception, self-care confidence, self-care knowledge, health-related quality of life and health service use will take place at baseline, on completion of the programme and at 12 weeks thereafter. Generalized estimating equations and Cox regression examine the intervention effects. Bootstrapping technique will be conducted to examine the cost-effectiveness of the intervention. The study is formally funded in December 2016. Discussion Chronic heart failure is associated with high level of hospital admissions, of which 40% is avoidable through effective self-care. Although self-care confidence is known to improve self-care, no structured educative method has been developed to enhance this attribute. This study addresses this research gap with a stringent application of theory and research design. Impact The study illustrates the application of the empowerment model for self-care enhancement in patients with chronic heart failure. The findings will inform the ways and values of this care model to enhance the disease management of this expanding clinical cohort.
