Abstract
BackgroundPrimary health care is changing as it responds to demographic shifts, technological changes and fiscal constraints. This, and predicted pressures on medical and nursing workforces, raises questions about staffing configurations. Physician assistants (PAs) are mid-level practitioners, trained in a medical model over 2 years at postgraduate level to work under a supervising doctor. A small number of general practices in England have employed PAs.ObjectiveTo investigate the contribution of PAs to the delivery of patient care in primary care services in England.DesignA mixed-methods study conducted at macro, meso and micro organisational levels in two phases: (1) a rapid review, a scoping survey of key national and regional informants, a policy review, and a survey of PAs and (2) comparative case studies in 12 general practices (six employing PAs). The latter incorporated clinical record reviews, a patient satisfaction survey, video observations of consultations and interviews with patients and professionals.ResultsThe rapid review found 49 published studies, mainly from the USA, which showed increased numbers of PAs in general practice settings but weak evidence for impact on processes and patient outcomes. The scoping survey found mainly positive or neutral views about PAs, but there was no mention of their role in workforce policy and planning documents. The survey of PAs in primary care (n = 16) found that they were mainly deployed to provide same-day appointments. The comparative case studies found that physician assistants were consulted by a wide range of patients, but these patients tended to be younger, with less medically acute or complex problems than those consulting general practitioners (GPs). Patients reported high levels of satisfaction with both PAs and GPs. The majority were willing or very willing to consult a PA again but wanted choice in which type of professional they consulted. There was no significant difference between PAs and GPs in the primary outcome of patient reconsultation for the same problem within 2 weeks, investigations/tests ordered, referrals to secondary care or prescriptions issued. GPs, blinded to the type of clinician, judged the documented activities in the initial consultation of patients who reconsulted for the same problem to be appropriate in 80% (n = 223) PA and 50% (n = 252) GP records. PAs were judged to be competent and safe from observed consultations. The average consultation with a physician assistant is significantly longer than that with a GP: 5.8 minutes for patients of average age for this sample (38 years). Costs per consultation were £34.36 for GPs and £28.14 for PAs. Costs could not be apportioned to GPs for interruptions, supervision or training of PAs.ConclusionsPAs were found to be acceptable, effective and efficient in complementing the work of GPs. PAs can provide a flexible addition to the primary care workforce. They offer another labour pool to consider in health professional workforce and education planning at local, regional and national levels. However, in order to maximise the contribution of PAs in primary care settings, consideration needs to be given to the appropriate level of regulation and the potential for authority to prescribe medicines. Future research is required to investigate the contribution of PAs to other first contact services as well as secondary services; the contribution and impact of all types of mid-level practitioners (including nurse practitioners) in first contact services; the factors and influences on general practitioner and practice manager decision-making as to staffing and skill mix; and the reliability and validity of classification systems for both primary care patients and their presenting condition and their consequences for health resource utilisation.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
BACKGROUND This paper describes the central role of 'external' evaluation, provided by an independent researcher, in developing an innovative curriculum for new professional roles with surgery. Workforce changes affecting the National Health Service provided an opportunity to develop 2 new roles and design training programmes to support them. The perioperative specialist practitioner (PSP) role was designed from scratch, while surgical care practitioner (SCP) training built on existing practice. Training programmes combined formal modules at Imperial College London (approximately 48 days over 10 months) with supervised clinical practice in each participant's base hospital. Programmes balanced factual knowledge, clinical and communication skills, professional issues and personal development and used a range of innovative techniques. EVALUATION METHODS A qualitative approach based on a utilisation-focused model monitored the development and implementation of 4 pilot PSP and SCP training programmes. A total of 124 individual and 48 group interviews were conducted at intervals over 3 years, sampling course participants, the project team clinical supervisors and administrators. An independent researcher collected, analysed and presented data at key stages, feeding back findings to the project team as the programmes evolved. DISCUSSION Effective training programmes for new roles can be developed, but the process is time-consuming and requires sensitivity. An independent evaluator offers great benefits, modulating the collaborative partnership between participants and project team. Positive responses (relating to content and teaching methods) from our study enabled us to refine a learner-centred programme. Negative responses often demanded immediate action to address important concerns, and evaluation provided early warning. External evaluation provides a vital perspective in the development of curricula supporting new roles.
