Evaluating Advanced Clinical Practitioners’ Engagement With the Four Pillars of Advanced Practice in the UK: A Scoping Review

Aims/Background Despite national frameworks outlining the four pillars of advanced practice (clinical practice, leadership and management, education, and research), engagement of Advanced Clinical Practitioners (ACPs) in the UK remains inconsistent, and significant challenges persist. This scoping review aimed to explore ACPs’ engagement with each pillar and to identify both successful and challenging factors. Methods A scoping review was conducted following Arksey and O’Malley’s framework in 2005 and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. A systematic search was undertaken across five databases (CINAHL, MEDLINE, Scopus, PsycInfo, and Cochrane Library) and grey literature sources. The search covered studies published from 2017 to 2025, in line with the introduction of the Multi-professional Framework. A three-stage screening process was used to identify eligible studies, and data were extracted using a standardised form. Thematic analysis was employed to synthesise the findings. Results Thirty-three studies met the inclusion criteria. The review identified strong ACP engagement in clinical practice, including contributions to direct patient care, improved patient satisfaction, and reduced waiting times. However, engagement with the leadership, education, and research pillars was inconsistent and often limited by excessive workload, lack of protected time, and ambiguity in role definitions. Structural variation across National Health Service (NHS) trusts further contributed to disparities in advanced clinical practice role development and utilisation. Conclusion Advanced clinical practice roles are firmly embedded in clinical care but remain underutilised in leadership, research, and education. Addressing these disparities requires clearer career pathways, organisational investment, and structured policy support to enable ACPs to contribute fully across all four pillars of practice.
