Implementation of the Nursing Associate in the NHS: A Rapid Realist Synthesis to Understand Mechanisms of Integration and Workforce Development

Aim(s) To develop theories about how Nursing Associate (NA) roles are implemented and working within NHS practice: What works, for whom, in what contexts and how? Methods Rapid realist synthesis of: (1) empirical and grey literature; (2) realist interviews with stakeholders. Sources were analysed using a realist approach that explored the data for novel or causal insights to generate initial programme theories. Results Empirical and grey sources ( n = 15) and transcripts from stakeholder interviews ( n = 11) were synthesised which identified three theory areas relating to NA implementation: (1) Scope of NA role: Communication and expectations; (2) Variations to the NA model of working; and (3) Career progression: Entry point, stepping stone and career in itself. Conclusion The NA holds the potential to improve nursing workforce stability by encouraging locally based, non‐registered healthcare staff to transition to an NA. However, the lack of collective understanding of the NA scope of practice can cause staff friction. It is unknown whether this friction will reduce over time or if staff divisions will lead to further deterioration of the workforce. Implications for the Profession and/or Patient Care Ongoing clear communication regarding NA scope of practice needs to be provided to aid understanding of their supplementary role and its potential contribution to nursing teams. Impact This work represents a first step to support both researchers and nursing workforce leaders in furthering knowledge of the impact of integrating NAs in diverse healthcare contexts and to unearth the mechanisms underpinning the success or failure of this new role. Reporting Method Realist and meta‐narrative evidence syntheses: Evolving standards. Community Inclusion and Engagement (CIE) Planning of the research design and interpretation of the results was completed with nurse clinicians with experience in the NA role.
