Abstract
BACKGROUND: Despite growing evidence for the effectiveness of digital cardiac rehabilitation (CR) uptake of this technology remains low. Understanding the factors that influence implementation of digital CR in clinical practice is a growing area of research. The aim of this nested qualitative study was to explore health worker perspectives on factors influencing implementation of a digital CR programme. METHODS: Using convenience sampling, semi-structured interviews were conducted with health workers, including health care professionals (nurses, dietitians, physiotherapists) and those in administrative and managerial roles who were involved in delivering and referring patients to Croí MySláinte, a 12-week digital CR intervention delivered during the Coronavirus 2019 pandemic. The updated Consolidated Framework for Implementation Research (CFIR) guided data collection and framework analysis. RESULTS: Interviews were conducted with 14 health workers. Factors influencing implementation of Croí MySláinte were multiple, with some operating independently and others in combination. They related to: (i) characteristics of individuals (e.g., senior leadership support, commitment and motivation of Health workers to meet patient needs, technical capability, workload and perceived fit with role); (ii) features of the programme (e.g., accessibility and convenience for patients, the digital platform, patient self- monitoring tools, the multidisciplinary team and core components); (iii) the external environment (e.g., partnership and connections between organisations, broadband and COVID-19); (iv) the internal environment (e.g., organisational culture, teamwork, resources including funding, digital infrastructure and staffing); and (v) the implementation process (e.g., engaging patients through provision of technical support). CONCLUSION: The study findings suggest that factors influencing implementation of digital CR operate at multiple levels. Therefore, multi-level implementation strategies are required if the true potential of digital health in improving equitable cardiac rehabilitation access, participation and patient outcomes is to be realised.
