Effects of Non-Pharmacological Interventions on the Biopsychosocial Health of Community-Dwelling Older Adults with Chronic Heart Failure: An Integrative Review

Background/Objectives: Chronic heart failure (CHF) is a leading cause of global morbidity and mortality, particularly among older adults, significantly impacting their quality of life and imposing a substantial economic burden. While pharmacological and surgical treatments remain essential, non-pharmacological interventions led by nurses are gaining prominence due to their comprehensive approach and biopsychosocial impact. The objective of this study was to synthesise and integrate such interventions for community-dwelling older adults with CHF. Methods: An integrative review was conducted in accordance with the Joanna Briggs Institute protocols and the PRISMA statement, utilising a systematic search across databases including PubMed and Cochrane. Qualitative, quantitative, and mixed-methods studies evaluating non-pharmacological interventions in the home setting were included, whilst those targeting non-specific populations were excluded. Following a rigorous screening process, 12 studies were selected, and their methodological quality was appraised based on study design. Results: The 12 included studies involved a total of 2466 participants and addressed interventions across the domains of education, physical activity, telehealth, and nutrition, with programme durations ranging from 4 weeks to 16 months. Notable improvements were observed in physical capacity, cognitive function, quality of life, and self-care capabilities, alongside potential reductions in hospitalisations reported in some studies. However, considerable methodological variability was identified across the literature. Conclusions: This review synthesises non-pharmacological nursing interventions for older adults with CHF, demonstrating varied benefits across multiple biopsychosocial domains. The findings emphasise the critical need for further research to evaluate the economic viability of these programmes and to adapt interventions to enhance the delivery of community-based care.
