GP workforce sustainability to maximise effective and equitable patient care: a realist review of what works, for whom and in what circumstances?

BACKGROUND: UK general practice has been described as being in crisis. A shortage and exodus of GPs is an urgent and challenging problem, attracting significant media attention, widespread public debate, and policy action. AIM: Our review aims to examine which aspects of the healthcare system affect GP workforce sustainability, how, why, and for whom. METHOD: A realist review is an interpretive, theory-driven approach to evidence synthesis, that brings together data from quantitative, qualitative, mixed methods research, and the wider grey literature (e.g., policy documentation). Using this data allows us to examine a diverse range of evidence with a clear focus on understanding factors which support (or hinder) GP workforce sustainability, how these are shaped by contexts, and the mechanisms that underpin them. We identify important individual and system-level contexts that may be amenable to change. RESULTS: We present our emerging findings in the form of a programme theory which explores human connection with patients, colleagues, and across organisations, gaining intellectual enrichment and learning systems comprising socially-situated knowledge. Relational continuity is key across these, supporting GP workforce sustainability. Challenges include standardisation, alienation and professional loneliness, inflexible organisation, and restrictive technologies. CONCLUSION: Our research generates new knowledge about the interdependencies between contexts, mechanisms, and outcomes. The findings can inform strategies and interventions intended to support, facilitate, and assist the GP workforce in delivering equitable and effective patient care. We identify critical gaps in knowledge and prioritise the expectations for scope and nature of future GP work and retention strategies.

General practitioner workforce sustainability to maximise effective and equitable patient care: a realist review protocol.

INTRODUCTION: There are not enough general practitioners (GPs) in the UK National Health Service. This problem is worse in areas of the country where poverty and underinvestment in health and social care mean patients experience poorer health compared with wealthier regions. Encouraging more doctors to choose and continue in a GP career is a government priority. This review will examine which aspects of the healthcare system affect GP workforce sustainability, how, why and for whom. METHODS AND ANALYSIS: A realist review is a theory-driven interpretive approach to evidence synthesis, that brings together qualitative, quantitative, mixed-methods research and grey literature. We will use a realist approach to synthesise data from the available published literature to refine an evidence-based programme theory that will identify the important contextual factors and underlying mechanisms that underpin observed outcomes relating to GP workforce sustainability. Our review will follow Pawson's five iterative stages: (1) finding existing theories, (2) searching for evidence, (3) article selection, (4) data extraction and (5) synthesising evidence and drawing conclusions. We will work closely with key stakeholders and embed patient and public involvement throughout the review process to refine the focus of the review and enhance the impact and relevance of our research. ETHICS AND DISSEMINATION: This review does not require formal ethical approval as it draws on secondary data from published articles and grey literature. Findings will be disseminated through multiple channels, including publication in peer-reviewed journals, at national and international conferences, and other digital scholarly communication tools such as video summaries, X and blog posts.
