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.

Role modelling to support careers in general practice: a realist review protocol.

BACKGROUND: Role models encountered during undergraduate training play an important part in shaping future doctors. They can act as powerful attractants towards, and deterrents away from a career in general practice. Many general practitioner (GP) educators who act as role models are burnt-out and wish to leave the profession which may limit their ability to influence students positively, with consequent detrimental impact on recruitment to the specialty. AIM: A realist review will be undertaken, aiming to explore how, why and for whom role modelling in undergraduate medical education can support medical students towards careers in general practice. DESIGN & SETTING: The realist review will follow Pawson's five steps, including: locating existing theories, searching for evidence, article selection, data extraction, synthesising evidence and drawing conclusions and will explore literature published in English language between 2013 and 2024. METHOD: An initial explanatory framework (initial programme theory, IPT) will be developed guided by a stakeholder panel including medical undergraduates, GPs and patient/public representatives. Searches will be developed and conducted in electronic databases and grey literature. Studies will be included if they explore the relationship between GP role modelling and undergraduate career choice and relevant data will be extracted. CONCLUSION: Findings will refine the initial programme theory, unveiling key contexts, mechanisms and outcomes which influence role modelling in undergraduate GP medical education and support or deter students from careers in general practice. These findings will support recommendations and interventions to facilitate positive outcomes, including improved recruitment to general practice.

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. PROSPERO REGISTRATION NUMBER: CRD42023395583.

Barriers and facilitators to establishing a clinical academic career in clinical education research in the UK: A focus group study.

In a rapidly changing healthcare environment, we need a robust evidence base to inform effective education and training. This study aimed to examine factors perceived to determine career progression in clinical education research in the UK. Six online focus groups were conducted, with 35 participants from a range of medical, dental, nursing, and allied health professions who identified as aspiring or early career clinical education researchers. Transcripts underwent thematic analysis. Two themes and associated subthemes were constructed to illustrate perceived factors impacting on career development: (1) A cultural challenge from clinical norms. Challenges included differences between the epistemological assumptions of biomedical and clinical research, and the underlying philosophy of education research, which is more closely aligned with the knowledge generation of the social sciences. This led to difficulty communicating the impact of education research to patient care. There were also blurred boundaries between education delivery and research, with the latter lacking a clearly defined group identity. (2) Structures, systems and relationships for career progression. Practical considerations included time and funding (or lack thereof), the opportunity to undertake formal training, networking and role models. This research highlights a number of systemic barriers and facilitators to careers in clinical education research and offers targets of intervention to enable a sustainable academic workforce in clinical education research.

Antigenic epitope targets of rhesus macaques self-curing from Schistosoma mansoni infection

The self-cure of rhesus macaques from a schistosome infection and their subsequent strong immunity to a cercarial challenge should provide novel insights into the way these parasites can be eliminated by immunological attack. High-density arrays comprising overlapping 15-mer peptides from target proteins printed on glass slides can be used to screen sera from host species to determine antibody reactivity at the single epitope level. Careful selection of proteins, based on compositional studies, is crucial to encompass only those exposed on or secreted from the intra-mammalian stages and is intended to focus the analysis solely on targets mediating protection. We report the results of this approach using two pools of sera from hi- and lo-responder macaques undergoing self-cure, to screen arrays comprising tegument, esophageal gland, and gastrodermis proteins. We show that, overall, the target epitopes are the same in both groups, but the intensity of response is twice as strong in the high responders. In addition, apart from Sm25, tegument proteins elicit much weaker responses than those originating in the alimentary tract, as was apparent in IFNγR KO mice. We also highlight the most reactive epitopes in key proteins. Armed with this knowledge, we intend to use multi-epitope constructs in vaccination experiments, which seek to emulate the self-cure process in experimental animals and potentially in humans.

How is transition to medical practice shaped by a novel transitional role? A mixed-methods study.

OBJECTIVES: This study considered a novel 'interim' transitional role for new doctors (termed 'FiY1', interim Foundation Year 1), bridging medical school and Foundation Programme (FP). Research questions considered effects on doctors' well-being and perceived preparedness, and influences on their experience of transition. While FiY1 was introduced in response to the COVID-19 pandemic, findings have wider and ongoing relevance. DESIGN: A sequential mixed-methods study involved two questionnaire phases, followed by semi-structured interviews. In phase 1, questionnaires were distributed to doctors in FiY1 posts, and in phase 2, to all new FP doctors, including those who had not undertaken FiY1. SETTING AND PARTICIPANTS: Participants were newly qualified doctors from UK medical schools, working in UK hospitals in 2020. 77% (n=668) of all participants across all phases had undertaken FiY1 before starting FP in August. The remainder started FP in August with varying experience beforehand. OUTCOME MEASURES: Questionnaires measured preparedness for practice, stress, anxiety, depression, burnout, identity, and tolerance of ambiguity. Interviews explored participants' experiences in more depth. RESULTS: Analysis of questionnaires (phase 1 n=441 FiY1s, phase 2 n=477 FiY1s, 196 non-FiY1s) indicated that FiY1s felt more prepared than non-FiY1 colleagues for starting FP in August (ß=2.71, 95% CI=2.21 to 3.22, p<0.0001), which persisted to October (ß=1.85, CI=1.28 to 2.41, p<0.0001). Likelihood of feeling prepared increased with FiY1 duration (OR=1.02, CI=1.00 to 1.03, p=0.0097). Despite challenges to well-being during FiY1, no later detriment was apparent. Thematic analysis of interview data (n=22) identified different ways, structural and interpersonal, in which the FiY1 role enhanced doctors' emerging independence supported by systems and colleagues, providing 'supported autonomy'. CONCLUSIONS: An explicitly transitional role can benefit doctors as they move from medical school to independent practice. We suggest that the features of supported autonomy are those of institutionalised liminality-a structured role 'betwixt and between' education and practice-and this lens may provide a guide to optimising the design of such posts.

Constraints and affordances for UK doctors-in-training to exercise agency: A dialogical analysis.

INTRODUCTION: The goal of medical education is to develop clinicians who have sufficient agency (capacity to act) to practise effectively in clinical workplaces and to learn from work throughout their careers. Little research has focused on experiences of organisational structures and the role of these in constraining or affording agency. The aim of this study was to identify priorities for organisational change, by identifying and analysing key moments of agency described by doctors-in-training. METHODS: This was a secondary qualitative analysis of data from a large national mixed methods research programme, which examined the work and wellbeing of UK doctors-in-training. Using a dialogical approach, we identified 56 key moments of agency within the transcripts of 22 semi-structured interviews with doctors based across the UK in their first year after graduation. By analysing action within the key moments from a sociocultural theoretical perspective, we identified tangible changes that healthcare organisations can make to afford agency. RESULTS: When talking about team working, participants gave specific descriptions of agency (or lack thereof) and used adversarial metaphors, but when talking about the wider healthcare system, their dialogue was disengaged and they appeared resigned to having no agency to shape the agenda. Organisational changes that could afford greater agency to doctors-in-training were improving induction, smoothing peaks and troughs of responsibility and providing a means of timely feedback on patient care. CONCLUSIONS: Our findings identified some organisational changes needed for doctors-in-training to practise effectively and learn from work. The findings also highlight a need to improve workplace-based team dynamics and empower trainees to influence policy. By targeting change, healthcare organisations can better support doctors-in-training, which will ultimately benefit patients.

Dentists' preparedness to provide Level 2 services in the North East of England: a mixed methods study.

Background Dentists capable of delivering Level 2 complexity treatments may benefit patient access to dental care and increase workforce morale. However, little is known about attitudes, capability and training needs relating to Level 2 dental services.Aims To examine attitudes to, and perceived readiness for delivery of Level 2 dental services by NHS dentists in the North East of England and North Cumbria.Method A sequential mixed methods study with an online survey and semi-structured interviews. Participants were general, community, and hospital-based dental practitioners. Descriptive statistics of survey and thematic analysis of qualitative data were undertaken.Results Overall, 56% of 124 respondents had a limited understanding of the Level 2 performer role. A minority felt they were already providing Level 2 care across all speciality areas; 9% (n = 11) had a professional portfolio suitable for Level 2 accreditation. Confidence to undertake Level 2 competencies varied by speciality area, being highest in paediatric dentistry, and lowest in endodontics and orthodontics. Qualitative data identified motivations, and personal, organisational and system factors that were seen as barriers or enablers to upskilling.Conclusion The regional NHS workforce is unprepared to provide Level 2 dental services. Successful introduction will require review of necessary infrastructure and transparency of accreditation and contracting processes.

Clinical support during COVID-19: An opportunity for service and learning? A cross-sectional survey of UK medical students.

PURPOSE: Medical students providing support to clinical teams during Covid-19 may have been an opportunity for service and learning. We aimed to understand why the reported educational impact has been mixed to inform future placements. METHODS: We conducted a cross-sectional survey of medical students at UK medical schools during the first Covid-19 'lockdown' period in the UK (March-July 2020). Analysis was informed by the conceptual framework of service and learning. RESULTS: 1245 medical students from 37 UK medical schools responded. 57% of respondents provided clinical support across a variety of roles and reported benefits including increased preparedness for foundation year one compared to those who did not (p < 0.0001). However, not every individual's experience was equal. For some, roles complemented the curriculum and provided opportunities for clinical skill development, reflection, and meaningful contribution to the health service. For others, the relevance of their role to their education was limited; these roles typically focused on service provision, with few opportunities to develop. CONCLUSION: The conceptual framework of service and learning can help explain why student experiences have been heterogeneous. We highlight how this conceptual framework can be used to inform clinical placements in the future, in particular the risks, benefits, and structures.[Box: see text].

Real-time patients' perspectives about participating in teaching consultations in primary care: A questionnaire study.

INTRODUCTION: Patients presenting with undifferentiated illnesses provide valuable learning opportunities for medical students. Evidence detailing the factors that affect patient participation in undergraduate medical education is limited. This study examines how patients regard their participation in teaching consultations in primary care. METHODS: We conducted a cross-sectional questionnaire survey in four GP practices. We tested the relationship between variables of interest and willingness to participate, using hierarchical logistic regression. RESULTS: We analysed 525 questionnaires. 88% of respondents were willing to have students take part in their consultation, and 72% were willing to see a student alone before seeing the doctor. Older patients and those with less sensitive clinical problems were more likely to participate. Willingness to participate was also associated with patients' perceptions of certain costs and benefits of participation. Respondents had poor knowledge about medical education, and a sizeable minority perceived a lack of autonomy about the presence of students in their encounters. More than one-third of respondents expressed the presence of a clinician as a precondition for approval of students' performing some active roles. DISCUSSION: The findings have identified potential interventions to enhance patient involvement including patient education, respecting patient autonomy, and ensuring appropriate student supervision.

Epitope mapping of exposed tegument and alimentary tract proteins identifies putative antigenic targets of the attenuated schistosome vaccine

The radiation-attenuated cercarial vaccine remains the gold standard for the induction of protective immunity against Schistosoma mansoni. Furthermore, the protection can be passively transferred to naïve recipient mice from multiply vaccinated donors, especially IFNgR KO mice. We have used such sera versus day 28 infection serum, to screen peptide arrays and identify likely epitopes that mediate the protection. The arrays encompassed 55 secreted or exposed proteins from the alimentary tract and tegument, the principal interfaces with the host bloodstream. The proteins were printed onto glass slides as overlapping 15mer peptides, reacted with primary and secondary antibodies, and reactive regions detected using an Agilent array scanner. Pep Slide Analyzer software provided a numerical value above background for each peptide from which an aggregate score could be derived for a putative epitope. The reactive regions of 26 proteins were mapped onto crystal structures using the CCP4 molecular graphics, to aid selection of peptides with the greatest accessibility and reactivity, prioritizing vaccine over infection serum. A further eight MEG proteins were mapped to regions conserved between family members. The result is a list of priority peptides from 44 proteins for further investigation in multiepitope vaccine constructs and as targets of monoclonal antibodies.

Development and retention of the dental workforce: findings from a regional workforce survey and symposium in England.

BACKGROUND: To help promote a flexible and sustainable workforce in dentistry, it is necessary to access accurate and timely data about the structure and nature of the evolving dental team. This paper considers the results and learning from a region-wide dental workforce survey conducted in one area of Health Education England and how the team has changed since the last survey a decade earlier. METHODS: A mixed-methods approach comprised two phases. In Phase 1 a customised workforce questionnaire was sent to all dental practices registered with the Care Quality Commission in the North East of England and North Cumbria in March 2016. Findings then informed Phase 2, a regional symposium held in October 2016, where interactive workshops generated qualitative data that elaborated on factors influencing workforce development. RESULTS: Of 431 primary dental care practices identified, 228 questionnaires were returned - a 53% response rate. The largest professional groups were dental nurses (n = 1269, 53% by headcount; 50% of fte) and dentists (34% by headcount; 42% by fte), though there had been increases in numbers of all staff groups over the decade, which was most marked for dental therapists (from 1 per 39 dentists to 1 per 8 dentists). The dental team predominantly fell into 'younger' age groups (< 46 years age), with evidence of a significant increase in the number of dentists reporting part-time working in a practice since the last survey. Around one third of dental practices reported employing dental nurses with additional skills (n = 74, 32.5%) or dental therapists (n = 73, 32%), and nearly half employed a dental hygienist (n = 104, 46%). However, there was considerable variability in whether these staff actually carried out the range of skills within their scope of practice. Factors shaping workforce development were identified as, the national context, loss of expertise, patients' health needs and expectations, surgery premises and financial constraints. CONCLUSIONS: The composition and work patterns of the primary care dental workforce have changed markedly over the last decade, though utilisation of skill-mix continues to be constrained. Consideration of factors determining career progression of dentists and dental care professionals is needed to optimise a sustainable future workforce.

Mapping the epitopes of Schistosoma japonicum esophageal gland proteins for incorporation into vaccine constructs.

BACKGROUND: The development of a schistosome vaccine has proved challenging but we have suggested that characterisation of the self-cure mechanism in rhesus macaques might provide a route to an effective product. The schistosome esophagus is a complex structure where blood processing is initiated by secretions from anterior and posterior glands, achieved by a mixture of ~40 unique proteins. The mechanism of self-cure in macaques involves cessation of feeding, after which worms slowly starve to death. Antibody coats the esophagus lumen and disrupts the secretory processes from the glands, potentially making their secretions ideal vaccine targets. METHODOLOGY/PRINCIPAL FINDINGS: We have designed three peptide arrays comprising overlapping 15-mer peptides encompassing 32 esophageal gland proteins, and screened them for reactivity against 22-week infection serum from macaques versus permissive rabbit and mouse hosts. There was considerable intra- and inter-species variation in response and no obvious unique target was associated with self-cure status, which suggests that self-cure is achieved by antibodies reacting with multiple targets. Some immuno-dominant sequences/regions were evident across species, notably including: MEGs 4.1C, 4.2, and 11 (Array 1); MEG-12 and Aspartyl protease (Array 2); a Tetraspanin 1 loop and MEG-n2 (Array 3). Responses to MEGs 8.1C and 8.2C were largely confined to macaques. As proof of principle, three synthetic genes were designed, comprising several key targets from each array. One of these was expressed as a recombinant protein and used to vaccinate rabbits. Higher antibody titres were obtained to the majority of reactive regions than those elicited after prolonged infection. CONCLUSIONS/SIGNIFICANCE: It is feasible to test simultaneously the additive potential of multiple esophageal proteins to induce protection by combining their most reactive regions in artificial constructs that can be used to vaccinate suitable hosts. The efficacy of the approach to disrupt esophageal function now needs to be tested by a parasite challenge.
