The effectiveness of psychological interventions on self-care, psychological and health outcomes in patients with chronic heart failure-A systematic review and meta-analysis

Efforts aimed at promoting self-care were the cornerstone of HF disease management. Nurses play an important role in patient education and secondary prevention. Compared to other professionals, nurses have more patient contact opportunities and are more holistic in all aspects of disease management; therefore, more nurses can be trained to incorporate the brief psychological techniques (such as motivational interviews and cognitive behavior therapy) to maximize intervention effectiveness. The main limitation of the review is the moderate to high level of heterogeneity among the included studies, which may partially undermine the reliability and reproducibility of the results. Because of the heterogeneity among the studies, a conclusion on the optimal format and forms of the intervention could not be drawn. Replication of the studies will be required in the future to isolate the active intervention component and to identify the ideal intervention format and dosage.
