Feasibility of early digital health rehabilitation after cardiac surgery in the elderly: a qualitative study.

Abstract

Increasing numbers of elderly patients experience prolonged decreased functional capacity and impaired quality of life after seemingly successful cardiac surgery. After discharge from hospital, these patients experience a substantial gap in care until centre-based cardiac rehabilitation commences. They may benefit from immediate coaching by means of mobile health technology to overcome psychological and physiological barriers to physical activity. The aim of this study was to explore the usability, acceptability, and relevance of a mobile health application designed to support remote exercise-based cardiac rehabilitation of elderly patients early after cardiac surgery from the perspective of patients, their relatives, and physiotherapists. We adapted a home-based mobile health application for use by elderly patients early after cardiac surgery. Semi-structured dyadic interviews were conducted with a purposive sample of patients (n = 9), their spouses (n = 5), and physiotherapists (n = 2) following two weeks of the intervention. The transcribed interviews were analysed thematically. Three themes were identified: 1) creating an individual fit by tailoring the intervention; 2) prioritizing communication and collaboration; and 3) interacting with the mobile health application. Overall, the findings indicate that the mobile health intervention has the potential to promote engagement, responsibility, and motivation among elderly patients to exercise early after surgery. However, the intervention can also be a burden on patients and their relatives when roles and responsibilities are unclear. The mobile health intervention showed potential to bridge the intervention gap after cardiac surgery, as well as in fostering engagement, responsibility, and motivation for physical activity among elderly individuals. Nevertheless, our findings emphasize the necessity of tailoring the intervention to accommodate individual vulnerabilities and capabilities. The intervention may be improved by addressing a number of organizational and communicational issues. Adaptions should be made according to the barriers and facilitators identified in this study prior to testing the effectiveness of the intervention on a larger scale. Future research should focus on the implementation of a hybrid design that supplements or complements face-to-face and centre-based cardiac rehabilitation.
