Patient-public engagement interventions for health system improvement in Sub-Saharan Africa: A systematic scoping review protocol.

BACKGROUND
Research has found health system improvement cannot be achieved without continuously engaging patients, their families and all stakeholders in the design, management and delivery of health care services. Following the Alma Ata declaration on Primary Health Care in 1978, the focus of health system improvement has tended to shift from physician or hospital-centric approaches to a more democratic vision of engaging the public and/or patients in the commissioning, planning, organisation, operation and control of the health care system. Thus, patient-public engagement (PPE) has become an important tool in health system improvement particularly for countries with poor health outcomes including countries in sub-Saharan Africa which carries an estimated 24% of the global burden of diseases in both human and financial costs. The aim of this scoping review is to describe and systematically map PPE research in sub-Saharan Africa, and then to synthesise this research in relation to key theories of PPE, identify the key drivers and barriers of PPE and to identify the knowledge gaps that may usefully be addressed by future research.


METHODS
This scoping review will follow Arksey and O'Malley's best guidelines for conducting scoping reviews and also follow the standard guidelines for reporting using the Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews checklist. A systematic search of peer-reviewed English language literature published between January 1999 and December 2019 will be conducted on four databases: Scopus, CINAHL, Medline (Ovid) and Embase. The initial screening of titles and abstracts will be undertaken independently by two reviewers, followed by full text screening involving three independent reviewers. A thematic framework synthesis will be employed in the analysis of data to identify the various PPE interventions, and outcomes mapped to a framework of engagement continuum to understand its overall effect on health system improvement in sub-Saharan Africa.


DISCUSSION
To our knowledge, this scoping review will be the first to systematically investigate PPE interventions implemented across sub-Saharan Africa, map the outcomes of identified interventions to a framework of engagement continuum and to understand its overall effect on health system improvement. Findings of this review will be published in an open-access peer review journal and disseminated at scientific conferences.
