An intervention to support stroke survivors and their carers in the longer term (LoTS2Care): study protocol for the process evaluation of a cluster randomised controlled feasibility trial.

BACKGROUND

Whilst pathways relating to the early stages of stroke care have become well established, strategies for longer-term care are less developed and longer-term outcomes remain poor for many stroke survivors. New Start, a complex intervention that includes needs identification, exploration of social networks and components of problem-solving and self-management, was designed to improve stroke survivors' quality of life by addressing unmet needs and increasing participation. It is delivered approximately 6 months post-stroke by trained staff (facilitators). We are currently undertaking a cluster randomised feasibility trial of the New Start intervention with an embedded process evaluation, which is an important component of the design and testing of complex interventions as it provides an understanding of how interventions are delivered and function in different settings.

METHODS/

DESIGN

This mixed methods process evaluation will explore the degree to which New Start is implemented as intended, the impact of context on intervention delivery and the acceptability of the intervention for stroke survivors, their families and practitioners. It will include non-participant observation of facilitator training and intervention delivery. Interviews with stroke survivors, facilitators and other relevant staff (including administrators and managerial staff) will be undertaken. Qualitative data from interview transcripts, facilitator reflections and observational field notes will be analysed thematically alongside numerical data documenting intervention delivery collected as part of the trial.

DISCUSSION: This process evaluation will identify factors that aid and impede implementation of the New Start intervention and improve understanding of this novel approach to longer-term stroke care.
