The effects of a dyadic empowerment-based heart failure management (De-HF) programme on self-care and HRQL : a randomized controlled trial

Abstract Background The ever-growing epidemiology of heart failure (HF) and its detrimental impacts on patients’ quality of life and healthcare cost urge for effective interventions to ameliorate the modifiable prognostic factors. As substantial evidence suggests ineffective self-care as an important candidate especially for the post-discharge outcomes, various care approaches are developed to optimize this behavioral outcome. However, even family carers are heavily involved in the self-care process, dyadic approach to improve the health outcomes of both interactive partners are least applied in the HF transitional care model. Purpose To evaluate the effects of a dyadic empowerment-based heart failure management program (De-HF) on dyadic health and hospital service utilization outcomes. Methods This double-blind RCT randomized 88 HF patient-carer dyads to receive the De-HF program or a dialectic education program, after hospital discharge. Based on the Theory of Dyadic Illness Management, the 16-week De-HF Program, comprising i) a dyadic assessment, ii) five online empowerment modules and iii) follow-up telecare, integrated explicit strategies (scenario-based training, teach-back and goal-setting) to actively engage the care dyads in collaborative disease management. Figure 1 is the graphical presentation of the De-HF Program. The primary outcome is health-related quality of life (HRQL) of the care dyads. Secondary outcomes include patients’ self-care as well as shared care and perceived control of the dyad. Results The mean age of the HF patients was 76.8 (9.4). The patients were in moderate disease severity [NYHA II/II: 56/44%; mean LVEF = 42.5%]. Figure 2 shows the consort flow diagram. After adjusting the socio-demographic characteristic, two-way analysis of covariance showed that patients in the De-HF program showed significantly greater improvement in patients’ self-care domains [Mean difference in change of score (95% CI): Self-care maintenance = 7.15 (1.82-12.46),Cohen’s d = 0.26, p=0.009; Self-care management = 10.04(3.29-16.79), Cohen’s d=0.65, p=0.004; symptom perception = 15.59 (8.20-22.98), Cohen’s d=0.928, p<0.001] and Minnesota Living with Heart Failure score [Mean different in the change of score (95% CI) = -11.45 (-18.24 - -4.66). Cohen’s d = -0.742, p=0.001]. The patient-carer dyads also have significantly greater improvement in perceived control (p=0.001) and collaborative disease management in terms of joint decision-making (p=0.001) and sense of reciprocity (p=0.026). Conclusion Dyadic science has evolved in self-care research for HF. This trial provides the first evidence to inform the positive effects of a theory-based dyadic transitional care program in improving the collaborative self-care management in a family context and patient health outcome. Longer-term evaluation on the effects of De-HF program on health service utilization outcomes and cost-effectiveness will be followed.The De-HF Managment ProgramThe Consort Flow Diagram
