Abstract
INTRODUCTION: Public and patient involvement (PPI) in healthcare decisions at the health system-level (macro-level) has become increasingly important during recent years. Existing evidence indicates that PPI increase patient centredness and the democracy of healthcare decisions as well as patients' trust and acceptance of these decisions. However, different methods for PPI exist, and an overview of the outcomes and influential contextual factors has not yet been conducted. Therefore, this scoping review aims to provide an overview of the different methods used for PPI in health system decisionmaking and the reported outcomes and contextual factors for these methods. METHODS AND ANALYSIS: The structure of this protocol is guided by the advanced scoping studies framework of Arksey and O' Malley, developed by Levac, Colquhoun and O'Brien, and the PRISMA-ScR Statement. We will systematically search electronic databases (MEDLINE, Cochrane Library, Scopus, CINAHL, PDQ-Evidence, Web of Science and PsycINFO) for peer-reviewed literature and screen the reference lists of included studies. Additionally, we will search for relevant grey literature and consult experts from the field to identify further information. Studies focusing on PPI in the context of health policy decision-making at the macro-level will be eligible for full-text screening. Studies focusing on decisions at the individual treatment-level (micro-level) and the organisational-level (mesolevel) as well as those dealing with PPI in health research will be excluded. A qualitative analysis will dissect how the included studies define PPI and its desirable outcomes, the achieved outcomes and reported contextual factors. ETHICS AND DISSEMINATION: We will present the results at relevant conferences and in an open-access journal. Additionally, we will share them with the experts involved in the research process and consider ways in which to transfer the findings into practice. As only secondary and previously published information will be used, ethical approval is not necessary.
