The impact of patient and public involvement in healthcare services: A conceptual review spanning social sciences and health sciences

Abstract

To understand patient and public involvement (PPI) and its potential impact in the healthcare services more comprehensively, the social science literature on public participation in governing public services must be integrated with the health science literature. To facilitate planning and evaluation of PPI-activities, the aim of this article is to review conceptual discussions of involvement/participation and impact, and summarize and integrate these in a way that advances the conceptual understanding of impact of PPI in healthcare services. Based on the review, we present a conceptual integration chart of impact areas, categories and types. There are three overarching areas: (i) impact on individuals; (ii) impact on the health system; and (iii) impact on decision-making processes and society. The overarching areas contain the categories: (i) citizens, patients, and decision-makers; (ii) service provision, and public health; and (iii) decision-making, policy and state, and public and society. Under these categories, the most commonly encountered impact types are presented.
