Understanding the challenges and successes of implementing 'hybrid' interventions in healthcare settings: findings from a process evaluation of a patient involvement trial.

INTRODUCTION

'Hybrid' interventions in which some intervention components are fixed across sites and others are flexible (locally created) are thought to allow for adaptation to the local context while maintaining fidelity. However, there is little evidence regarding the challenges and facilitators of implementing hybrid interventions. This paper reports on a process evaluation of a patient safety hybrid intervention called Your Care Needs You (YCNY). YCNY was tested in the Partners at Care Transitions (PACT) randomised controlled trial and aimed to enhance older patients and their families' involvement in their care in order to achieve safer transitions from hospital to home.

METHODS

The process evaluation took place across eight intervention wards taking part in the PACT trial. 23 interviews and 37 informal conversations were conducted with National Health Service (NHS) staff. Patients (n=19) were interviewed twice, once in hospital and once after discharge. Interviews with staff and patients concerned the delivery and experiences of YCNY. Ethnographic observations (n=81 hours) of relevant activities (eg, multidisciplinary team meetings, handovers, etc) were undertaken.

RESULTS

The main finding relates to how staff understood and engaged with YCNY, which then had a major influence on its implementation. While staff broadly valued the aims of YCNY, staff from seven out of the eight wards taking part in the process evaluation enacted YCNY in a mostly task-based manner. YCNY implementation often became a hurried activity which concentrated on delivering fixed intervention components rather than a catalyst for culture change around patient involvement. Factors such as understaffing, constraints on staff time and the COVID-19 pandemic contributed towards a 'taskification' of intervention delivery, which meant staff often did not have capacity to creatively devise flexible intervention components. However, one ward with a sense of distributed ownership of YCNY had considerable success implementing flexible components.

DISCUSSION

Hybrid interventions may allow aspects of an intervention to be adapted to the local context. However, the current constrained and pressured environment of the NHS left staff with little ability to creatively engage with devising flexible intervention components, despite recognising the need for and being motivated to deliver the intervention.
