Abstract
BACKGROUND: Nonadherence to medication and low physical activity contribute to morbidity, mortality, and decreased quality of life among patients with chronic heart failure (CHF). Effective interventions that can be delivered during routine clinical care are lacking. OBJECTIVE: We aimed to adapt the feasible and cost-effective Adherence Improving self-Management Strategy (AIMS) for patients with human immunodeficiency virus (HIV) to CHF treatment. Subsequently, we determined its acceptability and feasibility. METHODS: Adherence Improving self-Management Strategy is a systematic, nurse-delivered counseling intervention blended with eHealth to facilitate patient self-management. We used the intervention mapping framework to systematically adapt AIMS-HIV to AIMS-CHF, while preserving essential intervention elements. Therefore, we systematically consulted the scientific literature, patients with CHF and nurses, and pretested intervention materials. RESULTS: Adherence Improving self-Management Strategy-HIV was modified to AIMS-CHF: a multiple-behavior change intervention, focused on medication adherence and physical activity. Key self-management determinants (such as attitudes, self-efficacy, and self-regulatory skills) and organization of care (such as specialized nurses delivering AIMS) were similar for HIV and heart failure care. The AIMS protocol, as well as material content and design, was systematically adapted to CHF. Preliminary testing suggests that AIMS-CHF is likely feasible and acceptable to patients with CHF and care providers. CONCLUSION: Using the intervention mapping protocol, AIMS-HIV could be systematically adapted to AIMS-CHF and seems acceptable and feasible. Evidence from the literature, behavioral theory, and input from nurses and patients were essential in this process. Adherence Improving self-Management Strategy-CHF should now be tested for feasibility and effectiveness in routine care.
