Abstract
Introduction Serenity is a Pan-European study to develop and evaluate the clinical effectiveness of a Shared Decision-Making Support Tool (SDMST) to support shared decisions about continuing or stopping Antithrombotic Therapy (ATT) for patients with advanced cancer towards the end of life. The Serenity Patient and Public Involvement (PPI) team aim to recruit and engage with public contributors (in all 8 countries) throughout the study to ensure that research processes are acceptable to participants, improve the quality and interpretation of data and ensure that the SDMST is appropriately designed and evaluated for the study population.
Method The Serenity PPI strategy is informed by researcher and public contributor experience, reviews of international and European PPI in healthcare research, understanding of the study protocol and study aims and objectives, a researcher survey (to understand their knowledge, experiences and expectations of PPI), and consultations with work package leads. A Public Involvement in Research Impact Toolkit is being used to assess the impact of PPI in throughout the study.
Results PPI has been implemented in all eight work packages and has provided useful insights to a realist review findings, focus of patient interviews, the interpretation of qualitative and quantitative data, and the conduct of the Delphi consensus study, the development of the SDMST and the design and conduct of the randomised control trial.
Discussion The PPI strategy has been designed to be flexible and responsive to facilitators and barriers to implementation across different research methodologies and in different countries. The positive impact of PPI has been transferable across all work packages, from contributing to the intervention programme theory to the development and evaluation of the SDSMT.
Conclusions Findings on the development and impact of our PPI strategy to produce recommendations to guide future implementation of PPI for multi-national studies to develop shared-decision making support tools.
