Purpose This study aimed to examine the effects of a Nurse-led Multicomponent Behavioral Activation (N-MBA) intervention on HRQoL, knowledge about AF, medication adherence and psychological distress among patients with AF. Methods This parallel two-arm randomized controlled trial recruited community-dwelling patients aged ≥65 years with a confirmed diagnosis of atrial fibrillation, moderate to high risk of stroke but not receiving oral anticoagulation. Participants were randomized in a 1:1 ratio to receive the N-MBA intervention or standard care. The 13-week intervention adopted a novel behavioral activation approach to equip AF patients as an active agent to manage the disease. It consisted of care components to prepare patients for shared decision-making by using a decision aid, an empowerment-based educational module covering relevant AF self-care topics and continuous support through telephone calls. A set of validated instruments was administered at baseline, immediate and 6 months post-intervention. Results A total of 252 participants were randomized to the intervention (n = 127) or control (n = 125) group. Compared with the control group, the intervention group showed greater improvements in HRQoL [β = 10.617, 95% confidence interval (CI) = 1.285 – 20.501, p = 0.023] and AF knowledge (β = 2.129, 95% CI =1.026 – 5.712, p <0.001) at immediate post-intervention. The effects on both outcomes sustained at 6-month follow-up time point. No significant between-group changes in medication adherence, anxiety and depression were detected. Participants in the intervention group were activated to raise their concerns about AF and its treatment with the attending doctors, and they perceived higher compatibility between patient and physician decisions of OAC use upon completion of the intervention. Conclusion The empowerment-based nurse-led intervention is effective at sustaining improvements in HRQoL, AF knowledge and treatment decision making in AF patients with moderate to high stroke risk. It does not increase their psychological distress.
