Contextual factors that influence adoption and sustainment of self-management support in cancer survivorship care: a practical application of theory with qualitative interviews.

Background: Self-management support (SMS) is a recommended component of cancer survivorship care that improves health-related quality of life and reduces healthcare utilisation. However, widespread implementation has been difficult to achieve, with a gap in the literature on system-wide implementation efforts. This study examines contextual factors perceived to influence SMS adoption and sustainment in cancer centres in the Republic of Ireland.

Method: Semistructured interviews were conducted with 47 key informants from 20 cancer organisations across community and hospital settings. Participants were asked to report the level of adoption and sustainment of SMS at their organisation. This information was used to categorise organisations as low, medium or high implementers. We conducted cross-case analysis following the principles of Framework Analysis. Using the Consolidated Framework for Implementation Research as a menu of constructs, we examined factors influencing adoption and sustainment and variation in levels of implementation.

Results: National policy, external accreditation, external financing opportunities and the presence of champions in organisations are influential early in the implementation process driving adoption. Healthcare provider-led programmes and evidence of SMS improving patient outcomes and aligning with an organisation's priorities are necessary to secure buy-in, particularly among senior leadership. An organisational culture of entrepreneurship enables adoption and sustainment, with resources and a culture supporting staff well-being enabling sustainment.

Conclusion: While national policy is a driver, additional factors related to programme attributes and local contextual features such as the presence of champions, organisational readiness and culture influence implementation. The results may be used for future evaluations of SMS implementation in cancer survivorship care and to inform the development of tailored implementation strategies.
