Primary research question What is the impact of different non-medical practitioner skill-mix in Emergency Departments (ED) and Urgent Treatment Centres (UTC) in acute hospitals on patient and service processes and outcomes? Background Increasing demand for emergency and urgent care has occurred alongside staffing shortage, particularly of doctors. Re-shaping of the workforce has resulted, including the introduction of non-medical practitioners (NMPs), such as nurse practitioners and physician associates. Despite 20 years of NMPs in EDs, there is limited evidence of effectiveness of individual roles, and none as to appropriate skill-mix of staff, at what level of independence from senior medical staff. Aim To explore how NMPs are being deployed and the impact of different skill-mix including NMPs in EDs and UTCs on patient experience, quality of care, clinical outcomes, activity, staff experience and costs in acute NHS trusts in England, in order to inform workforce decisions of clinicians, managers and commissioners. Methods A mixed methods study will be conducted in three phases. Phase One (months 1-12) aims to describe the rationale for, and configurations of, the NMP workforce in EDs/UTCs in England, and to develop analytical tools. The investigators will undertake and publish a scoping literature and policy review on NMP development and skill-mix outcomes, informed by interviews with senior NHS clinicians, managers, commissioners and lay representatives (Work package [WP] 1) NHS Digital and NHS Benchmarking national data, 2017-2021 will be used to describe quantitatively the NMP and other clinical workforce (skill-mix); and observation (WP2) will enable qualitative description of the level of independence/supervision of NMPs and doctors. WP1 and WP2 results will be triangulated in consultative activities with patient and public and NMP representatives, and the independent study steering committee, to develop three analytical tools: a skill-mix ratio classification, a quantitative measure of independence and supervision, and a logic model for NMP skill-mix (WP3). Phase two (months 13-18) aims to utilise the analytical tools to assess the impact of skill-mix ratios on national ED/UTC indicators of quality. •The investigators will conduct and publish a quasi-experimental study of associations of skill-mix ratio classifications with our primary outcome (rate of unplanned return to the ED/UTC in seven days, a proxy for clinical safety), secondary outcomes (national indicators of ED/UTC quality and performance), and cost-effectiveness. (WP4) Phase three (months 13-24) aims to explain the effectiveness and acceptability of skill-mix ratios through investigation in six local-level case study sites. The WP4 analysis will be repeated with added precise local quantitative data on NMP types (trust management information), controlling for level of independence/supervision of the clinician (collected via structured observation). Patient satisfaction will be added as an outcome, collected prospectively via questionnaire (WP5). The experience of including NMPs in the skill-mix will be investigated through qualitative interviews with patients and staff (WP6). In Phase four (months 25-30) the investigators will prepare a synthesis of findings, using the logic model, for structured discussion at a stakeholder event to prepare recommendations and outputs. Timelines for delivery The study will take place from March 2021 to August 2023. Anticipated impact and dissemination The research will generate new knowledge and understanding of optimum/most effective/impact of different skill-mix outcomes to translate into workforce models with our NHS partners. Commissioners, clinicians and managers will be able to assess their local skill-mix in relation to the guidance on (optimum) skill-mix outcomes. Dissemination throughout the study will include policy briefings, academic outputs, bite-size findings, conference presentations and social and mainstream media routes accessible to stakeholders.
