Patient and public involvement in Nordic healthcare research: a scoping review of contemporary practice

Abstract

Background: Over the past decades, there has been a growing international interest in user involvement in healthcare research. However, evidence on the management and impact of patient and public involvement in Nordic healthcare research remains limited. Objective: The aim was to explore and delineate the current state, practice, and impact of patient and public involvement in healthcare research across different areas of healthcare and patient populations in the Nordic countries. Methods: We conducted a scoping review using nine scientific databases and gray literature from 1992–2023. Sources were categorized as empirical or non-empirical. We used the Guidance for Reporting Involvement of Patients and the Public Short Form 2 checklist for reporting of patient and public involvement in healthcare research and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Results: A total of 56 publications were included, consisting of 39 empirical and 17 non-empirical sources. Gray literature varied among countries and institutions encompassing different types of documents. We found an increase in the number of publications on patient and public involvement in Nordic healthcare research. This was evidenced by the growing number of references and institutional initiatives intended at involving the public, indicating the increasing emphasis on patient and public involvement in Nordic healthcare research. The terminology used to describe patient and public involvement varied over time. However, there has been a gradual narrowing down of terms as the concept of PPI has become more integrated into research practices, particularly with the involvement of funding agencies. Conclusion: The utilization of patient and public involvement in Nordic healthcare research has substantially increased, proliferated, and gained widespread acceptance across diverse healthcare domains. The variety of approaches challenged our scoping review in terms of systematic description and impact. Patient and public involvement was applied in one or more research stages using different methodologies and terms. International agreement on terms and definitions is needed for reliable interpretation of the use of patient and public involvement in Nordic healthcare research.
