Supporting Physical Activity and Quality of Life in Older Adults with Coronary Heart Disease: Development of a Web-Based Nursing Intervention.

BackgroundCoronary heart disease (CHD) remains a leading cause of morbidity and mortality worldwide. For older adults, sustained engagement in physical activity after coronary revascularization is essential for secondary prevention and is strongly associated with improved quality of life. However, participation in traditional cardiac rehabilitation programs remains low in this population, highlighting the need for accessible, age-tailored alternatives.ObjectiveTo describe the development of Changeons ensemble, a French-language web-based nursing intervention designed to promote physical activity and quality of life among older adults with CHD.MethodologyThe intervention was developed by a multidisciplinary participatory planning group following the Intervention Mapping framework. A comprehensive needs assessment was conducted through a literature review and semi-structured interviews with older adults (n = 10). The subsequent steps included objective setting and intervention design guided by the Information-Motivation-Behavioral Skills model.ResultsThe needs assessment identified key needs in information, motivation, and self-efficacy and highlighted the importance of individualized professional support. Changeons ensemble was designed as a seven-session web-based intervention integrating educational content, reflexive activities, individualized written nursing feedback, action planning, self-monitoring through an electronic diary, a forum, and case stories. The intervention emphasizes flexibility and sensitivity to older adults' physical and emotional challenges following coronary revascularization.ConclusionThis study presents a systematically developed, theory-informed, web-based intervention that directly addresses the specific needs of older adult with CHD. Changeons ensemble offers a promising approach for supporting sustained physical activity and enhancing in quality of life in a population that remains underserved by conventional cardiac rehabilitation models.Trial Registration:ClinicalTrials.gov NCT06197347; https://clinicaltrials.gov/study/NCT06197347.
