Implementing a perioperative care of older people undergoing surgery (POPS) service: findings from a multi-site qualitative implementation study.

Background: The Perioperative care for Older People undergoing Surgery (POPS) service model is increasingly being implemented across care providers in the English and Welsh National Health Services.

Objective: The study aimed to produce evidence regarding clinical leaders' activities to implement POPS across different service contexts and to produce generalisable recommendations for future implementation.

Methods: A qualitative interview study was undertaken across six National Health Services hospitals with established POPS services. Interview participants were recruited on the basis of their direct involvement in the implementation and leadership of the service. Data collection involved semi-structured interviews with 26 people carried out between November 2022 and May 2023.

Results: The implementation of POPS is often hampered by a lack of managerial and financial support, and apprehension amongst surgeons and anaesthetist about new ways of working. POPS leaders address these through five interconnected activities, each targeted at a combination of implementation factors. (i) Securing management and financial support. (ii) Professional engagement. (iii) Evidence building as a resource for demonstrating the clinical and operational benefits of POPS. (iv) Communication and engagement activities to promote and legitimise POPS to stakeholder groups. (v) Designated and distributed leadership to promote and coordinate implementation activities and to spread the service to new pathways.

Conclusions: Through a combination of activities POPS can be effectively implemented across different organisational contexts. Some aspects of these activities can be guided by shared resources and learning across sites, but others require adaption to local contextual barriers and drivers.
