Purpose: To generate a large cohort of those in 2019 seriously considering applying to study Medicine, collecting data on a range of socioeconomic and other demographic factors that influence choice of medical schools and to link to other datasets to form a longitudinal study of progress through medical school and careers in medicine., Design: Cross-sectional questionnaire studies, part of the longitudinal UK Medical Applicant Cohort Study (UKMACS)., Setting: UK medical school admissions in 2020., Participants: UK residents aged 16+ and seriously considering applying to study Medicine. The cohort was primarily drawn from those registering in 2019 for the U(K)CAT (University Clinical Aptitude Test (formerly the UK Clinical Aptitude Test)) with additional potential applicants responding to an open call. Participants consented to their data being linked within the UK Medical Education Database., Findings to Date: UKMACS Wave 1 questionnaire respondents consisted of 6391 consenting respondents from across the UK. In 2019, 14 980 of the 17 470 UK-domiciled medicine applicants were first-time applicants. The questionnaires show that many of these applicants have a need for more help and guidance to make informed choices, with less advantaged groups reporting themselves as being at a disadvantage when applying due to limited understanding of information and limited access to guidance to enable informed and effective decision-making., Future Plans: To link the cohort with successive Universities and Colleges Admissions Service and other datasets to analyse outcomes of applications and establish national longitudinal evidence to understand how medical choices are made and how they impact on educational, career and workforce outcomes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Asthma is the most common chronic respiratory disease in children and adults. Asthma results in significant disease-related morbidity, healthcare costs and, in some cases, death. Despite efforts through implementation of national guidelines to improve asthma care, the UK has one of the highest asthma-related morbidity and mortality rates in the western world. New approaches are necessary to prevent asthma attacks in children and adults. The objectives of this study are to assess the association between demographic and clinical factors and asthma-related hospital admissions in children and adults, describe the epidemiology of asthma phenotypes among hospital attenders, and externally validate existing asthma risk prediction models., Methods and Analysis: This is a retrospective cohort study of children and adults with asthma. Data will be extracted from the Clinical Practice Research Datalink (CPRD) Aurum database, which holds anonymised primary care data for over 13 million actively registered patients and covers approximately 19% of the UK population. The primary outcome will be asthma-related hospital admissions. The secondary outcomes will be prescriptions of short courses of oral corticosteroids (as a surrogate measure for asthma exacerbations), a composite outcome measure including hospital admissions and prescriptions of short courses of oral corticosteroids and delivery of asthma care management following hospital discharge. The primary analysis will use a Poisson regression model to assess the association between demographic and clinical risk factors and the primary and secondary outcomes. Latent class analysis will be used to identify distinct subgroups, which will further our knowledge on potential phenotypes of asthma among patients at high risk of asthma-related hospital admissions. A Concordance statistic (C-statistic) and logistic regression model will also be used to externally validate existing risk prediction models for asthma-related hospitalisations to allow for the optimal model to be identified and evaluated provide evidence for potential use of the optimal performing risk prediction model in primary care., Ethics and Dissemination: This study was approved by the CPRD Independent Scientific Advisory Committee (reference number: 21_000512). Findings from this study will be published in a peer-reviewed journal and disseminated at national and international conferences., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Compared with the rest of the UK and Western Europe, England has high rates of the infectious disease tuberculosis (TB). TB is curable, although treatment is for at least 6 months and longer when disease is drug resistant. If patients miss too many doses (non-adherence), they may transmit infection for longer and the infecting bacteria may develop resistance to the standard drugs used for treatment. Non-adherence may therefore risk both their health and that of others. Within England, certain population groups are thought to be at higher risk of non-adherence, but the factors contributing to this have been insufficiently determined, as have the best interventions to promote adherence. The objective of this study was to develop a manualised package of interventions for use as part of routine care within National Health Services to address the social and cultural factors that lead to poor adherence to treatment for TB disease., Methods and Analysis: This study uses a mixed-methods approach, with six study components. These are (1) scoping reviews of the literature; (2) qualitative research with patients, carers and healthcare professionals; (3) development of the intervention; (4) a pilot randomised controlled trial of the manualised intervention; (5) a process evaluation to examine clinical utility; and (6) a cost analysis., Ethics and Dissemination: This study received ethics approval on 24 December 2018 from Camberwell St. Giles Ethics Committee, UK (REC reference 18/LO/1818). Findings will be published and disseminated through peer-reviewed publications and conference presentations, published in an end of study report to our funder (the National Institute for Health Research, UK) and presented to key stakeholders., Trial Registration Number: ISRCTN95243114 SECONDARY IDENTIFYING NUMBERS: University College London/University College London Hospitals Joint Research Office 17/0726.National Institute for Health Research, UK 16/88/06., Competing Interests: Competing interests: IA, MD, HK, KK, ML, MM, EP, AS and FW have no competing interests to declare.

Introduction: Chronic kidney disease (CKD) management in the UK is usually primary care based, with National Institute for Health and Care Excellence (NICE) guidelines defining criteria for referral to secondary care nephrology services. Estimated glomerular filtration rate (eGFR) is commonly used to guide timing of referrals and preparation of patients approaching renal replacement therapy. However, eGFR lacks sensitivity for progression to end-stage renal failure; as a consequence, the international guideline group, Kidney Disease: Improving Global Outcomes has recommended the use of a risk calculator. The validated Kidney Failure Risk Equation may enable increased precision for the management of patients with CKD; however, there is little evidence to date for the implication of its use in routine clinical practice. This study will aim to determine the impact of the Kidney Failure Risk Equation on the redesignation of patients with CKD in the UK for referral to secondary care, compared with NICE CKD guidance., Method and Analysis: This is a cross-sectional population-based observational study using The Health Improvement Network database to identify the impact of risk-based designation for referral into secondary care for patients with CKD in the UK. Adult patients registered in primary care and active in the database within the period 1 January 2016 to 31 March 2017 with confirmed CKD will be analysed. The proportion of patients who meet defined risk thresholds will be cross-referenced with the current NICE guideline recommendations for referral into secondary care along with an evaluation of urinary albumin-creatinine ratio monitoring., Ethics and Dissemination: Approval was granted by The Health Improvement Network Scientific Review Committee (Reference number: 18THIN061). Study outcomes will inform national and international guidelines including the next version of the NICE CKD guideline. Dissemination of findings will also be through publication in a peer-reviewed journal, presentation at conferences and inclusion in the core resources of the Think Kidneys programme., Competing Interests: Competing interests: HKB and PC have nothing to disclose.

Objective: To compare the risk of hospitalisation for conditions originating in the perinatal period between children conceived via assisted reproductive technology and those that are naturally conceived, differentiating by treatment type., Study Design, Setting and Participants: Population-based record-linkage study of children born after assisted reproduction in the UK between 2002 and 2009 (n=44 618), their naturally conceived siblings (n=8462) and matched naturally conceived population (n=89 072) controls linked to their hospital inpatient records up to 31 March 2016., Primary and Secondary Outcome Measures: Robust estimates of the overall and cause-specific risk of hospital admission for adverse perinatal events and the comparison of outcomes by type of treatment., Results: Over the study period, 17 132 (38.40%) children conceived via assisted reproduction and 30 306 (34.02%) and 1738 (20.54%) naturally conceived population and sibling controls, respectively, were admitted to the hospital for severe perinatal events. Compared with the population controls, singletons (Risk ratio (95% CI 1.30 (1.26, 1.34))) and twins (1.01 (0.99, 1.03)) conceived via assisted reproduction exhibited a higher risk of hospitalisation for any adverse perinatal event. However, no such increase was observed in the within-sibling analysis (0.97 (0.84, 1.12)). Similar patterns were seen for diagnoses related to length of gestation and fetal growth (vs population controls: 1.37 (1.29, 1.46); vs siblings: 1.17 (0.86, 1.60)); birth trauma (vs population controls: 1.23 (1.04, 1.44); vs siblings: 0.78 (0.47, 1.30)); respiratory and cardiovascular disorders (vs population controls: 1.28 (1.20, 1.38); vs siblings: 0.72 (0.53, 0.98)); infections (vs population controls: 1.30 (1.06, 1.59); vs siblings: 0,68 (0.24, 1.90)) and several other conditions. Associations were similar when comparing in vitro fertilisation to intracytoplasmic sperm injection and were higher when comparing fresh to frozen embryo transfers., Conclusion: Children conceived via assisted reproduction showed modest increases in the risk of hospitalisations for severe perinatal events when compared with population controls, although these findings were attenuated in the sibling analyses. The imprecision of within-sibling analyses highlights the need for larger studies to explore potential causal effects., Competing Interests: Competing interests: All authors have completed the Unified Competing Interest form (available on request from the corresponding author) and declare that SMN has participated in Advisory Boards and received speakers or consultancy fees from Access Fertility, Beckman Coulter, Ferring, Finox, Merck, MSD, Roche Diagnostics and The Fertility Partnership.

Objective: This paper provides an in-depth examination of public attitudes towards salt reduction across seven culturally diverse countries: the USA, the UK, France, Japan, Indonesia, Thailand, and Brazil., Design: Cross-sectional regression analysis with questionnaire data., Setting: An analysis of questionnaire study in seven countries., Participants: The study's questionnaire collected responses from 7090 participants across seven countries with the mean age of respondents being 46.06 years (SD 16.96). The gender distribution encompassed 3473 men (49.12%), 3582 women (50.66%), 24 non-binary individuals (0.34%) and 11 who identified as 'other' (0.16%)., Primary and Secondary Outcome Measures: Attitudes toward sodium reduction were measured on a seven-point Likert scale., Results: Regression analysis revealed significant associations between attitudes towards sodium reduction and various factors across countries. Gender was a significant factor in France, with women showing less awareness than men (coefficient -0.123, 95% CI -0.237 to -0.008). Age was a significant factor in Japan and Thailand, with older generations exhibiting stronger awareness. Occupation was a significant factor in France (grocery, 0.678, 0.229 to 1.127) and Japan (food service, 0.792, 0.300 to 1.283). In France (0.090, 0.033 to 0.146) and Brazil (0.092, 0.040 to 0.144), attitudes towards reducing sugar intake were positively associated with sodium reduction attitudes. Government interventions showed varying impacts, with positive associations in Thailand (0.004, 0.001 to 0.008) and negative associations in France (-0.003 -0.005 to -0.000)., Conclusion: Our study reveals a complex array of factors shaping attitudes towards sodium reduction across seven countries. These findings support the need for nuanced, country-specific approaches in formulating sodium reduction strategies. Future research should validate these findings, explore further determinants and understand how attitudes translate into dietary behaviours., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives: Major trauma centres (MTCs) save lives but rehabilitation to support return-to-work (RTW) is lacking. This paper describes development of a vocational rehabilitation intervention (the ROWTATE intervention) to support RTW following traumatic injury., Design: Sequential and iterative person-based approach in four stages- Stage 1: review of evidence about the efficacy and mechanisms of RTW interventions; Stage 2: interviews (n=38) and focus groups (n=25) with trauma survivors and service providers in five UK MTCs to identify the issues, and challenges faced postinjury; Stage 3 : codesign workshops (n=43) with trauma stakeholders in MTCs to conceptually test and identify intervention delivery barriers/enablers; Stage 4: meetings (n=7) with intervention development working group (IDWG) to: (1) generate guiding principles, (2) identify key intervention features (process, components, mechanisms) to address unmet rehabilitation needs; (3) generate a logic model and programme theory to illustrate how the intervention works; and (4) develop a training package to support delivery., Results: Trauma survivors described unmet needs relating to early advice about RTW; psychological support; pain management; hidden disabilities (eg, fatigue); estimating recovery; and community, amputee and musculoskeletal rehabilitation. Mechanisms of effective interventions identified in the review included early intervention, colocation, employer engagement, case coordination and work accommodations. Intervention features identified by IDWG members (n=13) from stages 1 and 2 were use of stepped-care approaches by occupational therapists (OTs) and clinical psychologists (CPs), OT/CP formulation for complex cases, assessment of mental health problems, individually tailored rehabilitation including vocational goal setting, cross-sector coordination/communication, employer engagement, phased RTW, education/advice for family/employers, exploration of work alternatives, ongoing review of physical and mental health needs, work stability monitoring. Conceptual testing ratified the logic model. Geography and long waiting lists were identified as potential delivery barriers., Conclusions: Real-world testing of the intervention is underway in a randomised controlled trial., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Military service members need to be able to operate under conditions of extreme stress to ensure the success of their team's mission; however, an acute stress reaction (ASR) can compromise team safety and effectiveness by rendering an individual unable to function. Building on an intervention originally developed by the Israel Defense Forces, several countries have developed, tested, and disseminated a peer-based intervention to help service members manage acute stress in others. This paper reviews how five countries (Canada, Germany, Norway, the UK and the USA) adjusted the protocol to fit their organisational culture while retaining essential elements of the original procedure, suggesting there can be interoperability and mutual intelligibility in the management of ASR by military allies. Future research should examine the parameters of effectiveness for this intervention, the impact of intervention on long-term trajectories, and individual differences in managing ASR., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Purpose: This paper reports on trainees' perceptions of leadership and leadership development, to inform the support that may be provided to them. It draws on a formative evaluation of the new role of clinical leadership mentor (CLM), introduced by Health Education England South-West in 2018. CLMs are responsible for 'overseeing the process and progress of leadership development among the trainees within their Trust/Local Education Provider'., Methods: The evaluation was a formative evaluation, based on interviews with CLMs, trainees and trainers and a survey of trainees and trainers. Recruitment was through 8 of the 19 CLMs in the South West. A report for each participating CLM was available to support the development of their individual role. In exploring trainees' perceptions of leadership and leadership development, this paper draws on data from trainees: 112 survey returns which included over 7000 words of free text data and 13 interviews., Findings: Our findings suggest a more nuanced understanding of leadership in medical trainees than was previously reported in the literature, and a wider acceptance of their leadership role. We highlight the problem of considering postgraduate doctors as a homogeneous group, particularly with reference to specialty. We also highlight that the organisational context for leadership development can be supportive or non-supportive. Leadership learning through genuine leadership experience with appropriate support from trainers and the wider Trust offers opportunities for both trainees and Trusts., Practical Implications: Trainees are accepting of their roles as leaders. The value of leadership learning through genuine leadership experience was highlighted. Improving the environment for leadership development offers Trusts and trainees opportunities for genuine service improvement., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: In the UK, one in four patients are in work at the time of their hip or knee replacement surgery. These patients receive little support about their return to work (RTW). There is a need for an occupational support intervention that encourages safe and sustained RTW which can be integrated into National Health Service practice. We developed a two-arm intervention trial, based on a feasibility study, to assess whether an occupational support intervention (the OPAL (Occupational support for Patients undergoing Arthroplasty of the Lower limb) intervention) is effective in supporting a reduced time to full, sustained RTW compared with usual care in patients undergoing hip and knee replacement., Methods and Analysis: This is a multicentre, individually randomised controlled superiority trial comparing the OPAL intervention to usual care. 742 working adults listed for elective primary hip or knee replacement, who intend to RTW, will be randomised to the OPAL intervention or usual care. The intervention comprises: (1) multimedia information resources; and (2) support from a designated RTW coordinator. The primary outcome is time until 'full' sustained RTW without sick leave for a consecutive 4-week period. Secondary outcomes are: time to any RTW, measures of functional recovery, number of 'sick days' between surgery and 'full' sustained RTW and the use of workplace modifications to facilitate their return. A health economic evaluation and a mixed methods process evaluation will assess cost-effectiveness and the implementation, fidelity and acceptability of the intervention, respectively. Outcomes will be collected at baseline, 3, 6, 9 and 12-month follow-up time points, as well as a monthly RTW questionnaire., Ethics and Dissemination: Dissemination will focus on supporting the wider adoption and implementation of the intervention (if effective) and will target groups for whom the results will be relevant. This trial was approved by West Midlands-Edgbaston REC 23/WM/0013., Trial Registration Number: ISRCTN13694911., Competing Interests: Competing interests: Professor Catriona McDaid is a Senior Journal Editor at NIHR Journals Library.

Introduction: Missed fractures are the most frequent diagnostic error attributed to clinicians in UK emergency departments and a significant cause of patient morbidity. Recently, advances in computer vision have led to artificial intelligence (AI)-enhanced model developments, which can support clinicians in the detection of fractures. Previous research has shown these models to have promising effects on diagnostic performance, but their impact on the diagnostic accuracy of clinicians in the National Health Service (NHS) setting has not yet been fully evaluated., Methods and Analysis: A dataset of 500 plain radiographs derived from Oxford University Hospitals (OUH) NHS Foundation Trust will be collated to include all bones except the skull, facial bones and cervical spine. The dataset will be split evenly between radiographs showing one or more fractures and those without. The reference ground truth for each image will be established through independent review by two senior musculoskeletal radiologists. A third senior radiologist will resolve disagreements between two primary radiologists. The dataset will be analysed by a commercially available AI tool, BoneView (Gleamer, Paris, France), and its accuracy for detecting fractures will be determined with reference to the ground truth diagnosis. We will undertake a multiple case multiple reader study in which clinicians interpret all images without AI support, then repeat the process with access to AI algorithm output following a 4-week washout. 18 clinicians will be recruited as readers from four hospitals in England, from six distinct clinical groups, each with three levels of seniority (early-stage, mid-stage and later-stage career). Changes in the accuracy, confidence and speed of reporting will be compared with and without AI support. Readers will use a secure web-based DICOM (Digital Imaging and Communications in Medicine) viewer (www.raiqc.com), allowing radiograph viewing and abnormality identification. Pooled analyses will be reported for overall reader performance as well as for subgroups including clinical role, level of seniority, pathological finding and difficulty of image., Ethics and Dissemination: The study has been approved by the UK Healthcare Research Authority (IRAS 310995, approved on 13 December 2022). The use of anonymised retrospective radiographs has been authorised by OUH NHS Foundation Trust. The results will be presented at relevant conferences and published in a peer-reviewed journal., Trial Registration Numbers: This study is registered with ISRCTN (ISRCTN19562541) and ClinicalTrials.gov (NCT06130397). The paper reports the results of a substudy of STEDI2 (Simulation Training for Emergency Department Imaging Phase 2)., Competing Interests: Competing interests: JV and DJ of the Steering Committee are employees of Gleamer SAS, France.

The 2014 West Africa Ebola virus disease outbreak prompted the deployment to Sierra Leone of non-governmental organisations and the UK Joint Inter-Agency Taskforce including personnel from the UK Defence Medical Services (DMS). Some of these military personnel partnered with the Republic of Sierra Leone Armed Forces (RSLAF) as an example of Defence Healthcare Engagement (DHE).UK DMS mentors assisted RSLAF to plan and upscale Ebola treatment units. Use of military analysis and planning tools facilitated robust and flexible plans to be produced while under significant time and resource constraints. Macrosimulation exercises enabled large numbers to be trained and standard operating procedures to be developed.Fundamental to success was a mutual respect between the DHE partners while maintaining host nation primacy throughout. DHE in this example offered advantages over non-governmental organisations. Transferable lessons for future DHE from the RSLAF-UK DMS partnership are described in this paper., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

This paper describes the range of Defence Engagement (Health) (DE(H)) activities between Northern Ireland and Ireland following the Good Friday Agreement in April 1998. Although the Agreement made provision for cross-border cooperation in health, the Omagh bombing of August 1998 energised the discussion to provide greater co-ordination of future responses to mass casualty events. The paper describes these DE(H) activities at the Strategic, Operational and Tactical levels to show the integration across these levels and between the agencies of both governments. The paper shows how a DE(H) programme can have a successful strategic effect by finding topics of mutual interest that can bring together two countries in order to provide an effective health and social care provision.

This paper describes the Defence Engagement (Health) (DE(H)) component of the medical mission within the UK deployment to South Sudan under Op TRENTON, the UK troop contribution to the United Nations Mission in South Sudan (UNMISS). The DE(H) activities provided advice and mentoring to the Vietnamese military medical services to support the predeployment preparation and training of their medical contingent that would undertake a relief in place of the UK personnel providing a Level 2 hospital in Bentiu, South Sudan. The paper describes these UK DE(H) activities at the strategic, operational and tactical levels to show the integration across these levels from January 2017 until the handover of command in South Sudan on 26 October 2018. The UK worked alongside personnel from the US and Australian military medical services to deliver a Field Training Exercise and other capability-building events for personnel from the Vietnamese 175 Military Hospital. The paper shows how a DE(H) programme can have strategic effects by bringing another nation into a United Nations mission, increasing UK diplomatic activity with a partner country, and by ensuring continuity of medical cover to a key UNMISS location after the withdrawal of the UK medical contingent.

Since the unanimous passing of United Nations Security Council Resolution 1325, which calls on member states to address gender inequality, many countries and the wider North Atlantic Treaty Organisation community have championed the Women Peace and Security agenda to empower women and reduce violence within fragile states. When women are empowered and actively involved in decision-making, there is less violence, and more peace and stability in that society, which benefits all members.Defence Medical Services are uniquely positioned to progress this agenda, particularly through its Defence Engagement activities. The UK's military medical community has more women in leadership than the wider military community. Our personnel can and should be used to model and empower military healthcare workers in partner nations.

Global health practice is becoming a key enabler within UK Defence and foreign policy. The definition of global health remains debated, though some important themes have been identified including: the multidisciplinary nature of global health, its ethical foundation and the political nature of global health. This paper contributes to the ongoing rational discourse that this important discipline deserves and recommends a framework and principles to apply to military health and care system strengthening in the Defence Engagement (Health) (DE(H)) practitioner role. DE(H) involves complex multiorganisational relationships and processes, and while practitioners should be mindful of the political nature of their role, the broad aims of preventing conflict and building stability mean DE(H) should contribute positively to global health.This paper forms part of a special issue of BMJ Military Health dedicated to Defence Engagement., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: To empirically investigate sustainability of development assistance for health (DAH), we conducted a retrospective case study on the Basic Health Services Project (BHSP) for rural health system strengthening, supported by the World Bank and the UK in China between 1998 and 2007. Specifically, this study examines the integration of the BHSP interventions into China's health system., Methods: From December 2021 to December 2022, we reviewed 64 published papers and project or policy documents, and conducted semistructured interviews with 22 key informants, ranging from managers of donor agencies and the government to township-level hospital directors. From February to March 2023, the data were analysed under an analytical framework for integration of targeted health interventions into health systems., Results: Evidence of the BHSP shows that the integration outcomes can vary by the levels of integration (national or subnational), geographical coverage (project areas or both project and non-project areas) and approach to integration (policy or routinisation). The country's health system reform facilitated the integration of the interventions relevant to the reform policies, as the BHSP was one of the pilot schemes. However, interventions incompatible with this broad context were integrated to a limited extent. This integration occurred through embedding the project within the existing system, with a higher degree of embeddedness leading to smoother integration. Cross-sectoral leading groups and a technical support system heightened the project visibility and enabled contextualised local adaptation, contributing to the smooth integration of the project interventions., Conclusion: The DAH-supported interventions can achieve sustainability by being integrated into the local health system. This integration can take various forms to improve health outcomes, including being accepted and internalised, modified as well as innovated and expanded. The host country and development partners can promote DAH sustainability by contextually integrating these interventions within the project scope., Competing Interests: Competing interests: None declared., (© World Health Organization 2024.

Introduction: Gestational diabetes mellitus and overweight are associated with an increased likelihood of complications during birth and for the newborn baby. These complications lead to increased immediate and long-term healthcare costs as well as reduced health and well-being in women and infants. This protocol presents the health economic evaluation to investigate the cost-effectiveness of Bump2Baby and Me (B2B&Me), which is a health coaching intervention delivered via smartphone to women at risk of gestational diabetes., Methods and Analysis: Using data from the B2B&Me randomised controlled trial, this economic evaluation compares costs and health effects between the intervention and control group as an incremental cost-effectiveness ratio. Direct healthcare costs, costs of pharmaceuticals and intervention costs will be included in the analysis, body weight and quality-adjusted life-years for the mother will serve as the effect outcomes. To investigate the long-term cost-effectiveness of the trial, a Markov model will be employed. Deterministic and probabilistic sensitivity analysis will be employed., Ethics and Dissemination: The National Maternity Hospital Human Research and Ethics Committee was the primary approval site (EC18.2020) with approvals from University College Dublin HREC-Sciences (LS-E-20-150-OReilly), Junta de Andalucia CEIM/CEI Provincial de Granada (2087-M1-22), Monash Health HREC (RES-20-0000-892A) and National Health Service Health Research Authority and Health and Care Research Wales (HCRW) (21/WA/0022).

Objectives: It is important that allied health professionals (AHPs) are prepared for clinical practice from the very start of their working lives to provide quality care for patients, for their personal well-being and for retention of the workforce. The aim of this study was to understand how well newly qualified AHPs were prepared for practice in the UK., Design: Systematic review., Data Sources: Embase, MEDLINE, CINAHL, ERIC and BEI were searched from 2012 to 2024. Grey literature searching and citation chasing were also conducted., Eligibility Criteria: We included primary studies reporting the preparedness for practice of UK graduates across 15 professions; all study types; participants included graduates who were up to 2 years postgraduation, their supervisors, trainers, practice educators and employers; and all outcome measures., Data Extraction and Synthesis: A standardised data extraction form was used. Studies were quality assessed using the Quality Appraisal for Diverse Studies tool. 10% of articles were independently double-screened, extracted and quality assessed; 90% was completed by one researcher., Results: 14 reports were included (9 qualitative, 3 mixed-method and 2 quantitative). Six papers focused on radiographers, three on a mixture of professions, two on paramedics, and one each on physiotherapists, clinical psychologists and orthotists. An important finding of the review is the paucity and low-medium quality of research on the topic. The narrative synthesis tentatively suggests that graduates are adequately prepared for practice with different professions having different strengths and weaknesses. Common areas of underpreparedness across the professions were responsibility and decision-making, leadership and research. Graduates were generally well prepared in terms of their knowledge base., Conclusion: High-quality in-depth research is urgently needed across AHPs to elucidate the specific roles, their nuances and the areas of underpreparedness. Further work is also needed to understand the transition into early clinical practice, ongoing learning opportunities through work, and the supervision and support structures in place., Prospero Registration Number: CRD42022382065., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives: To evaluate how the codesigned training programme, 'No conversation too tough', can help cancer, palliative and wider healthcare professionals support patients to communicate with their dependent children when a parent is dying. We examined perceptions of learning provided by the training, its contribution to confidence in communicating with families when a parent is dying, and subjective experience of, and reactions to, the training. We also explored potential changes in practice behaviours., Design: Pre-post, convergent, parallel, mixed-methods study. Motivations for practice change were measured quantitatively, and qualitatively through semi-structured interviews. Non-parametric analysis was conducted for self-efficacy and outcome expectancy measures; descriptive statistics examined perceptions of usefulness; intentions to use learning in practice and reactions to the training. Semi-structured interviews examined motivations and perceptions of learning in depth. A 6-week, practice log recorded immediate practice effects and reflections., Setting: 1-day training delivered 3 times, total delegates 36: online December 2021, February 2022, face-to-face March 2022. Questionnaires delivered correspondingly in online or paper formats, semi-structured interviews online., Participants: Pre-post: palliative care professionals (n=14/12), acute cancer clinical nurse specialists (n=16/11), other healthcare professionals (n=5/5)., Results: Positive changes were observed in self-efficacy (17 of 19 dimensions p<0.003) and outcome expectancies (3 of 14 beliefs p<0.036). Perceptions of usefulness and intentions to use learning in practice mean scores were 82-94 (scales 0=low to 100=high). There was high affirmation for sharing learning and influencing change in the workplace and wider practice. Content, style and delivery were positively endorsed. Further elements to be included in the training were identified., Conclusions: The training programme has the potential to effect change in practice behaviours. A large-scale study will evaluate the roll-out of the training delivered to individual professionals and whole teams across the UK. It will provide longer-term feedback to understand practice behaviour and mediators of change across professional roles., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: This is the fourth phase of a longitudinal cohort study (2022-2023) to investigate the health and well-being of UK serving (Regulars and Reservists) and ex-serving personnel (veterans) who served during the era of the Iraq and Afghanistan conflicts. The cohort was established in 2003 and has collected data over three previous phases including Phase 1 (2004-2006), Phase 2 (2007-2009) and Phase 3 (2014-2016)., Methods and Analysis: Participants are eligible to take part if they completed the King's Centre for Military Health Research Health and Wellbeing Cohort Study at Phase 3 (2014-2016) and consented to be recontacted (N=7608). Participants will be recruited through email, post and text message to complete an online or paper questionnaire. Data are being collected between January 2022 and September 2023. Health and well-being measures include measures used in previous phases that assess common mental disorders, post-traumatic stress disorder (PTSD) and alcohol misuse. Other areas of interest assess employment, help-seeking and family relationships. New topics include the impact of the British withdrawal from Afghanistan in 2021, complex PTSD (C-PTSD), illicit drug use, gambling and loneliness. Analyses will describe the effect size between groups deployed to Iraq and/or Afghanistan or not deployed, and those who are currently in service versus ex-service personnel, respectively, reporting prevalences with 95% CIs, and ORs with 95% CI. Multivariable logistic and multiple linear regression analyses will be conducted to assess various health and well-being outcomes and associations with risk and protective factors., Ethics and Dissemination: Ethical approval has been granted by the Ministry of Defence Research Ethics Committee (Ref: 2061/MODREC/21). Participants are provided with information and agree to a series of consent statements before taking part.

Introduction: The UK military operates a Heat Illness Clinic (HIC) to aid the return to exercise, training and occupational duty recommendations for individuals who have suffered exertional heat illness or heatstroke. This paper describes the process of assessment and reports representative data from n=22 patients referred to the HIC., Method: The assessment included clinical consultation, and measurement of maximal oxygen consumption (V̇O 2 max) and a heat tolerance test (HTT) conducted on a treadmill in an environmental chamber with an air temperature of 34°C and 44% relative humidity. Patients began the HTT wearing military clothing, carrying a rucksack (mass 15 kg) and walking at 60% V̇O 2 max, at 30 min the rucksack and jacket were removed and the T-shirt at 45 min, individuals continued walking for 60-90 min. Patients were considered heat tolerant if rectal temperature achieved a plateau., Results: N=14 patients were heat tolerant on the first assessment and of the n=8 patients required to return for repeat assessment, five were heat tolerant on the second assessment and the remaining three on the third assessment., Conclusions: In conjunction with patient history and clinical evaluation, the HTT provides a physiological basis to assist with decisions concerning patient management and return to duty following an episode of heat illness., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objectives: The shortage of healthcare staff is a global problem. UK mental health services have, on average, a higher turnover of staff than the NHS. Factors affecting retention of this staff group need to be explored in more depth to understand what is working for whom, for what reasons and in what circumstances. This review aims to conduct a realist synthesis to explore evidence from published studies, together with stakeholder involvement to develop programme theories that hypothesise how and why retention occurs in the mental health workforce and identify additional evidence to explore and test these theories thereby highlighting any persistent gaps in understanding. This paper develops programme theories that hypothesise why retention occurs and in what context and tests these theories thereby highlighting any persistent gaps in understanding., Methods: Realist synthesis was used to develop programme theories for factors affecting retention of UK mental health staff. This involved: (1) stakeholder consultation and literature scoping to develop initial programme theories; (2) structured searches across six databases to identify 85 included relevant literature relating to the programme theories; and (3) analysis and synthesis to build and refine a final programme theory and logic model., Results: Phase I combined findings from 32 stakeholders and 24 publications to develop six initial programme theories. Phases II and III identified and synthesised evidence from 88 publications into three overarching programme theories stemming from organisational culture: interconnectedness of workload and quality of care, investment in staff support and development and involvement of staff and service users in policies and practice., Conclusions: Organisational culture was found to have a key underpinning effect on retention of mental health staff. This can be modified but staff need to be well supported and feel involved to derive satisfaction from their roles. Manageable workloads and being able to deliver good quality care were also key., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: To ascertain the priorities of research in surgical interventions and aftercare in foot and ankle conditions in adults, from inclusive viewpoints of patients, carers, allied professionals and clinicians, as a collaboration with James Lind Alliance (JLA) Priority Setting Partnership. Setting A UK-based national study organised through British Orthopaedic Foot and Ankle Society (BOFAS)., Design: A cross-section of both medical and allied professionals, with patient involvement, submitted their 'top priorities' pertaining to foot and ankle pathology, using both paper and web-based formats, which were synthesised into the primary priorities. Following this, workshop-based reviews were used to determine the top 10 priorities., Participants: Adult patients, carers, allied professionals and clinicians who have experienced or managed foot and ankle conditions in the UK., Methods: A transparent and well-established process developed by JLA was carried out by a steering group of 16 members. A broad survey was designed and disseminated to the public via clinics, BOFAS meetings and website, JLA platforms and electronic media to establish potential research priority questions. Surveys were analysed and initial questions were categorised and cross-referenced with the literature. Those questions that were out of scope and sufficiently answered by research were excluded. The unanswered questions were ranked by the public via a second survey. The top 10 questions were finalised via an extensive workshop., Results: 472 questions from 198 responders were received from the primary survey. 71% (140) from healthcare professionals, 24% (48) from patients and carers and 5% (10) from other responders. 142 questions were out of scope, leaving 330 questions. These were summarised into 60 indicative questions. Reviewing against current literature, 56 questions were left. From the secondary survey, there were 291 respondents: 79% (230) healthcare professionals and 12% (61) patients and carers. After the secondary survey, the top 16 questions were brought to the final workshop to finalise the top 10 research questions. The top 10 questions were: What are the best outcome measures (ways of assessing the effect of the treatment) after foot and ankle surgery? What treatment is the best for Achilles tendon pain? What is the best treatment (including surgery) for tibialis posterior dysfunction (tendon on the inner side of the ankle), leading to a successful long-term outcome? Should physiotherapy be provided following foot and ankle surgery and is there an optimal amount needed to restore function after foot and ankle surgery? At what stage should a patient with ankle instability (ie, an ankle that keeps giving way) be considered for surgical treatment? How effective are steroid injections in improving pain from arthritis in the foot and ankle? What is the best surgery for bone and cartilage defects in the talus? What is better, ankle fusion or ankle replacements? What is the success of surgical lengthening of the calf muscle in improving forefoot pain? What is the best time to start weight bearing after ankle fusion/replacement surgery?, Conclusion: Top 10 themes included outcomes following interventions, for example, range of movement, reduction in pain, rehabilitation, which included physiotherapy to optimise post intervention outcomes, rehabilitation and condition-specific treatments. These questions will aid to guide national research into foot and ankle surgery. It will also help national funding bodies to prioritise areas of research interest to improve patient care., Competing Interests: Competing interests: This work received funding from the British Orthopaedic Foot and Ankle Society.

Introduction: Whole-systems approaches are being adopted to tackle physical inactivity. The mechanisms contributing to changes resulting from whole-systems approaches are not fully understood. The voices of children and families that these approaches are designed for need to be heard to understand what is working, for whom, where and in what context. This paper describes the protocol for the children and families' citizen science evaluation of the Join Us: Move, Play (JU:MP) programme, a whole-systems approach to increasing physical activity in children and young people aged 5-14 years in Bradford, UK., Methods and Analysis: The evaluation aims to understand the lived experiences of children and families' relationship with physical activity and participation in the JU:MP programme. The study takes a collaborative and contributory citizen science approach, including focus groups, parent-child dyad interviews and participatory research. Feedback and data will guide changes within this study and the JU:MP programme. We also aim to examine participant experience of citizen science and the suitability of a citizen science approach to evaluate a whole-systems approach. Data will be analysed using framework approach alongside iterative analysis with and by citizen scientists in the collaborative citizen science study., Ethics and Dissemination: Ethical approval has been granted by the University of Bradford: study one (E891-focus groups as part of the control trial, E982-parent-child dyad interviews) and study two (E992). Results will be published in peer-reviewed journals and summaries will be provided to the participants, through schools or directly. The citizen scientists will provide input to create further dissemination opportunities., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

In 2015, the UK government published the National Strategic Defence and Security Review (SDSR) 2015, which laid out their vision for the future roles and structure of the UK Armed Forces. SDSR 2015 envisaged making broader use of the Armed Forces to support missions other than warfighting. One element of this would be to increase the scale and scope of defence engagement (DE) activities that the UK conducts overseas. DE activities traditionally involve the use of personnel and assets to help prevent conflict, build stability and gain influence with partner nations as part of a short-term training teams. This paper aimed to give an overview of the Specialist Infantry Group and its role in UK DE. It will explore the reasons why the SDSR 2015 recommended their formation as well as an insight into future tasks., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To conduct an early-phase feasibility study of an oral health intervention, Health visitors delivering Advice on Britain on Infant Toothbrushing (HABIT), delivered by Health Visitors to parents of children aged 9-12 months old., Design: A mixed-methods, early-phase, non-controlled, feasibility study., Participants: Recruitment consisted of Group A-HABIT-trained Health Visitors (n=11) and Group B-parents of children aged 9-12 months old about to receive their universal health check (n=35)., Setting: Bradford, West Yorkshire, UK., Intervention: A multidisciplinary team co-developed digital and paper-based training resources with health visitors and parents of young children. The intervention comprised of two components: (A) training for health visitors to deliver the HABIT intervention and (B) HABIT resources for parents, including a website, videos, toothbrushing demonstration and a paper-based leaflet with an oral health action plan., Primary and Secondary Outcome Measures: Recruitment, retention and intervention delivery were analysed as key process outcomes for Groups A and B. Group B demographics, self-reported toothbrushing behaviours, dietary habits and three objective measures of toothbrushing including plaque scores were collected at baseline, 2 weeks and 3 months post intervention., Results: HABIT intervention delivery was feasible. Although the intended sample size was recruited (Group A=11 and Group B=35) it was more challenging than anticipated. Retention of Group B participants to final data collection was satisfactory (n=26). Total compliance with toothbrushing guidelines at baseline was low (30%), but significantly improved and was maintained 3 months after the intervention (68%). Plaque scores improved post intervention and participants found video recording of toothbrushing acceptable. Dietary habits remained largely unchanged., Conclusion: This feasibility study has demonstrated that HABIT is an appropriate oral health intervention. Adaptions to the study design are recommended to maximise recruitment and data collection in a definitive study. These quantitative findings have demonstrated an early signal of impact for improved oral health behaviours for young children at high risk of decay., Trial Registration Number: ISRCTN55332414., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: The drive towards engaging UK doctors in clinical leadership and management has involved many initiatives at various levels., Methods: This paper reports on the findings of an in-depth evaluation of a national medical leadership programme for doctors in the late stages of specialty or general practitioner (GP) training or have just become consultants or GPs., Results: The evaluation clearly demonstrates the impact of this programme and the benefits for the individuals and organisations involved, particularly around stimulating a shift in mood and a major mindset shift in what medical leadership is (and is not) and what they can achieve as medical leaders. The programme structure and activities allowed participants to learn from a range of senior decision-makers about policy and strategic developments and processes. However, the evaluation also highlighted that some pervasive myths still exist around medical leadership and management which, if not addressed, will hamper efforts to fully engage doctors in taking on strategic leadership roles., Conclusion: Clinical leadership programmes are valuable, but must be carefully managed to extract the full value from them., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: This paper explored the self-reported prevalence of depression, anxiety and stress among junior doctors during the COVID-19 pandemic. It also reports the association between working conditions and psychological distress experienced by junior doctors., Design: A cross-sectional online survey study was conducted, using the 21-item Depression, Anxiety and Stress Scale and Health and Safety Executive scale to measure psychological well-being and working cultures of junior doctors., Setting: The National Health Service in the UK., Participants: A sample of 456 UK junior doctors was recruited online during the COVID-19 pandemic from March 2020 to January 2021., Results: Junior doctors reported poor mental health, with over 40% scoring extremely severely depressed (45.2%), anxious (63.2%) and stressed (40.2%). Both gender and ethnicity were found to have a significant influence on levels of anxiety. Hierarchical multiple linear regression analysis outlined the specific working conditions which significantly predicted depression (increased demands (β=0.101), relationships (β=0.27), unsupportive manager (β=-0.111)), anxiety (relationships (β=0.31), change (β=0.18), demands (β=0.179)) and stress (relationships (β=0.18), demands (β=0.28), role (β=0.11))., Conclusions: The findings illustrate the importance of working conditions for junior doctors' mental health, as they were significant predictors for depression, anxiety and stress. Therefore, if the mental health of junior doctors is to be improved, it is important that changes or interventions specifically target the working environment rather than factors within the individual clinician., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To support workforce deficits and rising demand for medicines, independent prescribing (IP) by nurses, pharmacists and allied health professionals is a key component of workforce transformation in UK healthcare. This systematic review of qualitative research studies used a thematic synthesis approach to explore stakeholders' views on IP in primary care and identify barriers and facilitators influencing implementation., Setting: UK primary/community care., Participants: Inclusion criteria were UK qualitative studies of any design, published in the English language. Six electronic databases were searched between January 2010 and September 2021, supplemented by reference list searching. Papers were screened, selected and quality-appraised using the Quality Assessment Tool for Studies with Diverse Designs. Study data were extracted to a bespoke table and two reviewers used NVivo software to code study findings. An inductive thematic synthesis was undertaken to identify descriptive themes and interpret these into higher order analytical themes. The Diffusion of Innovations and Consolidated Framework for Implementation Research were guiding theoretical anchors., Primary and Secondary Outcome Measures: N/A., Results: Twenty-three articles addressing nurse, pharmacist and physiotherapist IP were included. Synthesis identified barriers and facilitators in four key stages of implementation: (1) 'Preparation', (2) 'Training', (3) 'Transition' and 4) 'Sustainment'. Enhancement, substitution and role-specific implementation models reflected three main ways that the IP role was used in primary care., Conclusions: In order to address global deficits, there is increasing need to optimise use of IP capability. Although the number of independent prescribers continues to grow, numerous barriers to implementation persist. A more coordinated and targeted approach is key to overcoming barriers identified in the four stages of implementation and would help ensure that IP is recognised as an effective approach to help alleviate workforce shortfalls in the UK, and around the world., Prospero Registration Number: CRD42019124400., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To assess the percentage of people in the UK with cough, fever or loss of taste or smell who have not had a positive COVID-19 test result who had been to work, to shops, socialised or provided care to a vulnerable person in the 10 days after developing symptoms. To investigate whether these rates differed according to the type of symptom, what the participant thought the cause of their symptoms was and whether they had taken a COVID-19 test., Design: Four online cross-sectional surveys using non-probability quota sampling method (n=8547)., Setting: Data were collected across the UK from 20 September to 3 November 2021, via a market research company., Participants: Aged over 16 years living in the UK., Primary Outcome Measures: Out-of-home activity., Results: 498 participants reported one or more symptoms and had not had a positive COVID-19 test result. Within that group, about half of employed participants had attended work while symptomatic (51.2%-56.3% depending on the symptom, 95% CIs 42.2% to 65.6%). Rates of other contact behaviours ranged from 31.4% (caring for a vulnerable person after developing a cough: 95% CI 24.3% to 38.4%) to 61.5% (shopping for groceries or pharmacy after developing a cough: 95% CI 54.1% to 68.9%). There were no differences according to type of symptom experienced or what the participant felt might be the cause. People who had taken a COVID-19 test were less likely to go out shopping for non-essentials than people who had not taken a test., Conclusion: Many people in the UK with symptoms of an infectious disease were not following government advice to stay at home if they believed they had an infectious illness. Reducing these rates may require a shift in our national attitude to the acceptability of people attending work with infectious illnesses., Competing Interests: Competing interests: All authors had financial support from NIHR for the submitted work; RA is an employee of the UK Health Security Agency; HP has received additional salary support from Public Health England and NHS England; HP receives consultancy fees to his employer from Ipsos MORI and has a PhD student who works at and has fees paid by Astra Zeneca; at the time of writing GJR is acting as an expert witness in an unrelated case involving Bayer PLC, supported by LES; no other financial relationships with any organisations that might have an interest in the submitted work in the previous three years; no other relationships or activities that could appear to have influenced the submitted work.

Objectives: To determine the factors contributing to the junior doctor workforce retention crisis in the UK using evidence collected directly from junior doctors, and to develop recommendations for changes to address the issue., Design: Integrative review., Data Sources: Searches were conducted on Ovid Medline and HMIC to locate evidence published between January 2016 and April 2021. This was supplemented by publications from relevant national organisations., Eligibility Criteria: English-language papers relating to UK junior doctor retention, well-being or satisfaction which contained data collected directly from junior doctors were included. Papers focusing solely on the pandemic, factors specific to one medical specialty, evaluation of interventions, or numerical data with no evidence relating to causation were excluded. Review papers were excluded., Data Extraction and Synthesis: Data were extracted and coded on NVivo by FKL, then thematic analysis was conducted., Results: 47 papers were included, consisting of academic (qualitative, quantitative, mixed and commentary) and grey literature. Key themes identified were working conditions, support and relationships, and learning and development, with an overarching theme of lack of flexibility. The outcomes of these factors are doctors not feeling valued, lacking autonomy, having a poor work-life balance, and providing compromised patient care. This results in need for a break from medical training., Conclusion: This review builds on findings of related literature regarding working environments, isolation, stigma, and desire for autonomy, and highlights additional issues around learning and training, flexibility, feeling valued, and patient care. It goes on to present recommendations for tackling poor retention of UK junior doctors, highlighting that the complex problem requires evidence-based solutions and a bottom-up approach in which junior doctors are regarded as core stakeholders during the planning of interventions., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: To investigate the perceptions and experiences of people with specific immune-mediated inflammatory diseases during the process of switching from Humira to biosimilar adalimumab., Design: Cross-sectional survey., Setting: An anonymised, self-administered, web-based survey., Participants: The participants were drawn from members and non-members of either the National Rheumatoid Arthritis Society, the National Axial Spondyloarthritis Society, Crohn's and Colitis UK, or Psoriasis Association. Birdshot Uveitis Society and Olivia's Vision also signposted to the survey links., Results: A total of 899 people living with various immune mediated inflammatory diseases participated in this survey. Thirty-four per cent of respondents reported poor overall satisfaction with their biosimilar adalimumab after the switch, associated with complaints related to the switching process including lack of shared decision making, scarcity of information provided by or signposted to by the department instigating the switch as well as lack of training with the new injection device. Where training with the new device had been provided, there were significantly reduced reports of pain when injecting the new biosimilar (OR 0.20, 95% CI 0.07 to 0.55), side effects (OR 0.17, 95% CI 0.06 to 0.47) and difficulty in using the new injection device (OR 0.25, 95% CI 0.15 to 0.41). Self-reported side effects were reduced by (OR 0.13, 95% CI 0.05 to 0.38) when written information was provided by healthcare professionals and by (OR 0.15, 95% CI 0.05 to 0.42) with provision of verbal information. Difficulty in using the new injection device was also reduced by provision of satisfactory information such as written documents (OR 0.38, 95% CI 0.23 to 0.63) or by verbal communication with healthcare professionals (OR 0.45, 95% CI 0.27 to 0.73). Finally, provision of satisfactory written or verbal information was associated with a reduction in any negative perception regarding symptom control with the new biosimilar by (OR 0.05, 95% CI 0.004 to 0.57) and by (OR 0.15, 95% CI 0.03 to 0.84), respectively., Conclusions: Patient reported experiences of the process of switching from originator to biosimilar emphasise the importance of clear communication, training and information in order to optimise perception and maximise achievable outcomes with the new treatment., Competing Interests: Competing interests: DP-A reports grants and other from AMGEN, grants, non-financial support and other from UCB Biopharma, grants from Les Laboratoires Servier, outside the submitted work; and Janssen, on behalf of IMI-funded EHDEN and EMIF consortiums, and Synapse Management Partners have supported training programmes organised by DPA’s department and open for external participants; CJ reports grants from Abbvie, grants from Amgen, grants from Biogen, grants from Eli Lilly, grants and other from Frensius Kabi, grants from Gilead, grants from Janssen, grants from Medac, grants from Pfizer, grants from Roche, grants from UCB, grants from BMS, grants from Sanofi, outside the submitted work; AB reports grants from the following companies that are outside of and not related to the submitted paper: Abbvie, Amgen, Biogen, Eli Lilly, Fresenius Kabi, Gilead, Janssen, Medac, Pfizer, Roche, Sanofi, UCB, BMS; SD reports grants from AbbVie, grants from Biogen, grants from Eli Lilly, grants from Janssen-Cilag, grants from Novartis, grants from UCB, outside the submitted work; SB reports grants from Abbvie, grants from Amgen, grants from Celgene, grants from Janssen, grants from Gilead, grants from MSD, grants from Roche, grants from Sandoz, grants from Takeda, during the conduct of the study; HM reports grants from Abbvie, grants from Almirall, grants from Amgen, grants from Celgene, grants from Eli Lilly, grants from Janssen, grants from LEO Pharma, grants from UCB, outside the submitted work; PCT reports personal fees from AbbVie, personal fees from Biogen, personal fees from Celltrion, personal fees from Fresenius Kabi, outside the submitted work., (© Author(s) (or their employer(s)) 2022.

The COVID-19 pandemic is an unprecedented global crisis in which governments had to act in a situation of rapid change and substantial uncertainty. The governments of Germany, Sweden and the UK have taken different paths allowing learning for future pandemic preparedness. To help inform discussions on preparedness, inspired by resilience frameworks, this paper reviews governance structures, and the role of science and the media in the COVID-19 response of Germany, Sweden and the UK in 2020. We mapped legitimacy, interdependence, knowledge generation and the capacity to deal with uncertainty.Our analysis revealed stark differences which were linked to pre-existing governing structures, the traditional role of academia, experience of crisis management and the communication of uncertainty-all of which impacted on how much people trusted their government. Germany leveraged diversity and inclusiveness, a 'patchwork quilt', for which it was heavily criticised during the second wave. The Swedish approach avoided plurality and largely excluded academia, while in the UK's academia played an important role in knowledge generation and in forcing the government to review its strategies. However, the vivant debate left the public with confusing and rapidly changing public health messages. Uncertainty and the lack of evidence on how best to manage the COVID-19 pandemic-the main feature during the first wave-was only communicated explicitly in Germany. All country governments lost trust of their populations during the epidemic due to a mix of communication and transparency failures, and increased questioning of government legitimacy and technical capacity by the public., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Introduction: The number of people living in homeless hostels in the UK has steadily increased over the past decade. Despite people experiencing homelessness often having considerable health problems and a range of complex needs frequently in association with addictions, the experiences of hostel staff and residents especially in relation to accessing health and social care support have seldom been explored. The aim of this paper is to identify the barriers and facilitators to accessing health and social care services for people living in homeless hostels., Design: Exploratory qualitative baseline data were collected as part of an intervention to facilitate palliative care in-reach into hostels., Setting/participants: Interviews were conducted with 33 participants; 18 homeless hostel managers/support staff and 15 people experiencing homelessness, from six homeless hostels in London and Kent., Results: Three themes were identified (1) internal and external service barriers to health and social care access due to stigma, lack of communication and information sharing from services and assumptions around capacity and the role of the hostel, (2) the impact of lack of health and social care support on hostel staff leading to burnout, staff going beyond their job role and continuous support given to residents, (3) potential facilitators to health and social care access such in-reach and support from those who understand this population and hostel staff training., Discussion: Residents have multiple complex needs yet both hostel staff and residents face stigma and barriers accessing support from external services. Positive relationships were described between hostel residents and staff, which can be an essential step in engaging with other services. People experiencing homelessness urgently need better access to person-centred, trauma-informed support ideally via in-reach from people who understand the needs of the population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objectives: To compare global warming potential (GWP) of hospitals converting from single-use sharps containers to reusable sharps containers (SSC, RSC). Does conversion to RSC result in GWP reduction?, Design: Using BS PAS 2050:2011 principles, a retrospective, before/after intervention quantitative model together with a purpose-designed, attributional 'cradle-to-grave' life-cycle tool, were used to determine the annual greenhouse gas (GHG) emissions of the two sharps containment systems. Functional unit was total fill line litres (FLL) of sharps containers needed to dispose of sharps for 1-year period in 40 trusts. Scopes 1, 2 and 3 emissions were included. Results were workload-normalised using National Health Service (NHS) national hospital patient-workload indicators. A sensitivity analysis examined areas of data variability., Setting: Acute care hospital trusts in UK., Participants: 40 NHS hospital Trusts using RSC., Intervention: Conversion from SSC to RSC. SSC and RSC usage details in 17 base line trusts immediately prior to 2018 were applied to the RSC usage details of the 40 trusts using RSC in 2019., Primary Outcome Measure: The comparison of GWP calculated in carbon dioxide equivalents (CO 2 e) generated in the manufacture, transport, service and disposal of 12 months, hospital-wide usage of both containment systems in the 40 trusts., Results: The 40 trusts converting to RSC reduced their combined annual GWP by 3267.4 tonnes CO 2 e (-83.9%); eliminated incineration of 900.8 tonnes of plastic; eliminated disposal/recycling of 132.5 tonnes of cardboard and reduced container exchanges by 61.1%. GHG as kg CO 2 e/1000 FLL were 313.0 and 50.7 for SSC and RSC systems, respectively. A sensitivity analysis showed substantial GHG reductions within unit processes could be achieved, however, their impact on relevant final GWP comparison varied <5% from base comparison., Conclusions: Adopting RSC is an example of a sustainable purchasing decision that can assist trusts meet NHS GHG reduction targets and can reduce GWP permanently with minimal staff behavioural change., Competing Interests: Competing interests: TRG is an international consultant on sharps injury prevention and sharps containment to healthcare facilities, professional associations and contractors in the healthcare sector, and from time to time, Sharpsmart UK (the manufacturer of the RSC studied in this paper) use his services. All other authors are employed by, or associated with, trusts using Sharpsmart reusable sharps containers and declare no conflicts of interest., (© Author(s) (or their employer(s)) 2021.

Introduction: The COVID-19 pandemic has resulted in significant morbidity and mortality and devastated economies globally. Among groups at increased risk are healthcare workers (HCWs) and ethnic minority groups. Emerging evidence suggests that HCWs from ethnic minority groups are at increased risk of adverse COVID-19-related outcomes. To date, there has been no large-scale analysis of these risks in UK HCWs or ancillary workers in healthcare settings, stratified by ethnicity or occupation, and adjusted for confounders. This paper reports the protocol for a prospective longitudinal questionnaire study of UK HCWs, as part of the UK-REACH programme (The United Kingdom Research study into Ethnicity And COVID-19 outcomes in Healthcare workers)., Methods and Analysis: A baseline questionnaire will be administered to a national cohort of UK HCWs and ancillary workers in healthcare settings, and those registered with UK healthcare regulators, with follow-up questionnaires administered at 4 and 8 months. With consent, questionnaire data will be linked to health records with 25-year follow-up. Univariate associations between ethnicity and clinical COVID-19 outcomes, physical and mental health, and key confounders/explanatory variables will be tested. Multivariable analyses will test for associations between ethnicity and key outcomes adjusted for the confounder/explanatory variables. We will model changes over time by ethnic group, facilitating understanding of absolute and relative risks in different ethnic groups, and generalisability of findings., Ethics and Dissemination: The study is approved by Health Research Authority (reference 20/HRA/4718), and carries minimal risk. We aim to manage the small risk of participant distress about questions on sensitive topics by clearly participant information that the questionnaire covers sensitive topics and there is no obligation to answer these or any other questions, and by providing support organisation links. Results will be disseminated with reports to Government and papers submitted to pre-print servers and peer reviewed journals., Trial Registration Number: ISRCTN11811602; Pre-results., Competing Interests: Competing interests: SC is Deputy Medical Director of the General Medical Council, UK Honorary Professor, University of Leicester.

Introduction: Gender identity development services (GIDS) worldwide have seen a significant increase in referrals in recent years. Many of these referrals consist of children and young people (CYP) who experience gender-related distress. This study aims to improve understanding of outcomes of CYP referred to the UK GIDS, specifically regarding gender identity, mental health, physical health and quality of life. The impact of factors such as co-occurring autism and early social transition on outcomes over time will be explored., Methods and Analysis: This is a prospective cohort study of CYP aged 3-14 years when referred to the UK GIDS. Eligible participants will be ≤14 years at the time their referral was accepted and will be on the waitlist for the service when baseline measures are completed. Children aged under 12 years will complete the measures in an interview format with a researcher, while young people aged 12 years and over and their parents/caregivers will complete online or paper-based questionnaires. Participants will complete follow-up measures 12 months and 24 months later. The final sample size is expected to be approximately 500. Logistic regression models will be used to explore associations between prespecified explanatory variables and gender dysphoria. Appropriate regression models will also be used to investigate explanatory variables for other outcomes. Subgroup analyses based on birth-assigned gender, age at referral and co-occurring autistic traits will be explored., Ethics and Dissemination: The study has been approved by the Health Research Authority and London - Hampstead Research Ethics Committee (reference: 19/LO/0857). The study findings will be published in peer-reviewed journals and presented at both conferences and stakeholder events. Findings will be used to inform clinical practice., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021. Re-use permitted under CC BY.

Objectives: To identify how frequently patient-reported outcomes (PROs) are used as primary and/or secondary outcomes in randomised controlled trials (RCTs) and to summarise what statistical methods are used for the analysis of PROs., Design: Comprehensive review., Setting: RCTs funded and published by the United Kingdom's (UK) National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme., Data Sources and Eligibility: HTA reports of RCTs published between January 1997 and December 2020 were reviewed., Data Extraction: Information relating to PRO use and analysis methods was extracted., Primary and Secondary Outcome Measures: The frequency of using PROs as primary and/or secondary outcomes; statistical methods that were used for the analysis of PROs as primary outcomes., Results: In this review, 37.6% (114/303) of trials used PROs as primary outcomes, and 82.8% (251/303) of trials used PROs as secondary outcomes from 303 NIHR HTA reports of RCTs. In the 114 RCTs where the PRO was the primary outcome, the most used PRO was the Short-Form 36 (8/114); the most popular methods for multivariable analysis were linear mixed model (45/114), linear regression (29/114) and analysis of covariance (13/114); logistic regression was applied for binary and ordinal outcomes in 14/114 trials; and the repeated measures analysis was used in 39/114 trials., Conclusion: The majority of trials used PROs as primary and/or secondary outcomes. Conventional methods such as linear regression are widely used, despite the potential violation of their assumptions. In recent years, there is an increasing trend of using complex models (eg, with mixed effects). Statistical methods developed to address these violations when analysing PROs, such as beta-binomial regression, are not routinely used in practice. Future research will focus on evaluating available statistical methods for the analysis of PROs., Competing Interests: Competing interests: The PhD study of YQ is financially sponsored by the University of Sheffield and China Scholarship Council (grant number 201908890049).

Objectives: In response to demographic and health system pressures, the development of non-medical advanced clinical practice (ACP) roles is a key component of National Health Service workforce transformation policy in the UK. This review was undertaken to establish a baseline of evidence on ACP roles and their outcomes, impacts and implementation challenges across the UK., Design: A scoping review was undertaken following JBI methodological guidance., Methods: 13 online databases (Medline, CINAHL, ASSIA, Embase, HMIC, AMED, Amber, OT seeker, PsycINFO, PEDro, SportDiscus, Osteopathic Research and PenNutrition) and grey literature sources were searched from 2005 to 2020. Data extraction, charting and summary was guided by the PEPPA-Plus framework. The review was undertaken by a multi-professional team that included an expert lay representative., Results: 191 papers met the inclusion criteria (any type of UK evidence, any sector/setting and any profession meeting the Health Education England definition of ACP). Most papers were small-scale descriptive studies, service evaluations or audits. The papers reported mainly on clinical aspects of the ACP role. Most papers related to nursing, pharmacy, physiotherapy and radiography roles and these were referred to by a plethora of different titles. ACP roles were reported to be achieving beneficial impacts across a range of clinical and health system outcomes. They were highly acceptable to patients and staff. No significant adverse events were reported. There was a lack of cost-effectiveness evidence. Implementation challenges included a lack of role clarity and an ambivalent role identity, lack of mentorship, lack of continuing professional development and an unclear career pathway., Conclusion: This review suggests a need for educational and role standardisation and a supported career pathway for advanced clinical practitioners (ACPs) in the UK. Future research should: (i) adopt more robust study designs, (ii) investigate the full scope of the ACP role and (iii) include a wider range of professions and sectors., Competing Interests: Competing interests: RC is Clinical Lead for Musculoskeletal Practitioners in Primary Care and Lead of the Centre for Advancing Practice, Health Education England.

Objectives: This paper reports findings identifying foundation and junior doctors' experiences of occupational and psychological protective factors in the workplace and sources of effective support., Design: Interpretative, inductive, qualitative study involving in-depth interviews with 21 junior doctor participants. The interviews were audio-recorded, transcribed, anonymised and imported into NVivo V.11 to facilitate data management. Data were analysed using a thematic analysis employing the constant comparative method., Setting: National Health Service in the UK., Participants: Participants were recruited from junior doctors through social media (eg, the British Medical Association (BMA) junior doctors' Facebook group, Twitter and the mental health research charity websites). A purposive sample of 16 females and 5 males, ethnically diverse, from a range of specialities, across the UK. Junior doctor participants self-identified as having stress, distress, anxiety, depression and suicidal thoughts or having attempted to kill themselves., Results: Analysis identified three main themes, with corresponding subthemes relating to protective work factors and facilitators of support: (1) support from work colleagues - help with managing workloads and emotional support; (2) supportive leadership strategies, including feeling valued and accepted, trust and communication, supportive learning environments, challenging stigma and normalising vulnerability; and (3) access to professional support - counselling, cognitive-behavioural therapy and medication through general practitioners, specialist support services for doctors and private therapy., Conclusions: Findings show that supportive leadership, effective management practices, peer support and access to appropriate professional support can help mitigate the negative impact of working conditions and cultures experienced by junior doctors. Feeling connected, supported and valued by colleagues and consultants acts as an important buffer against emotional distress despite working under challenging working conditions., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Objectives: This paper reports findings exploring work cultures, contexts and conditions associated with psychological distress in foundation and junior doctors., Design: Qualitative study using in-depth interviews with 21 junior doctor participants. The interviews were audio-recorded, transcribed, anonymised and imported into NVivo V.11 to facilitate data management. Data were analysed using a thematic analysis employing the constant comparative method., Setting: NHS in England., Participants: A purposive sample of 16 female and five male junior doctor junior doctor participants who self-identified as having stress, distress, anxiety, depression and suicidal thoughts, or having attempted to kill themselves., Results: Analysis reported four key themes: (1) workload and working conditions; (2) toxic work cultures-including abuse and bullying, sexism and racism, culture of blaming and shaming; (3) lack of support; (4) stigma and a perceived need to appear invulnerable., Conclusion: This study highlights the need for future solutions and interventions targeted at improving work cultures and conditions. There needs to be greater recognition of the components and cumulative effects of potentially toxic workplaces and stressors intrinsic to the work of junior doctors, such as the stress of managing high workloads and lack of access to clinical and emotional support. A cultural shift is needed within medicine to more supportive and compassionate leadership and work environments, and a zero-tolerance approach to bullying, harassment and discrimination., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

This paper describes a framework for understanding military combat mental health based on the possible mental ill-health consequences of exposure to 'potential trauma events' for members of the armed forces and after their military service as veterans. It uses a life course approach that maps an individual's mental well-being against four 'states': fit, reacting, injured and ill. It then considers five categories of factors that influence the risk of mental illness from this exposure based on research evidence; prejoining vulnerability, resilience, precipitating, treatment and recovery. This framework offers a structure to debate current knowledge, inform policy and therapeutic interventions, provide education and to guide future research into the subject., Competing Interests: Competing interests: MB reports grants from UK Research and Innovation GCRF Research for Health in Conflict, during the conduct of the study and retired from the post of Surgeon General for the UK Defence Medical Services on 14 December 2018., (© Author(s) (or their employer(s)) 2021.

Objective: Prioritisation of important treatment uncertainties for 'Common Conditions Affecting the Hand and Wrist' via a UK-based James Lind Alliance Priority Setting Partnership., Setting: This process was funded by a national charitable organisation and based in the UK., Participants: Anyone with experience of common conditions affecting the adult hand and wrist, including patients, carers and healthcare professionals. All treatment modalities delivered by a hand specialist, including therapists, surgeons or other allied professionals, were considered., Interventions: Established James Lind Alliance Priority Setting Partnership methods were employed.Electronic and paper questionnaires identified potential uncertainties. These were subsequently confirmed using relevant, up-to-date systematic reviews. A final list of top 10 research uncertainties was developed via a face-to-face workshop with representation from patients and clinicians. Impact of research was sought by surveying hand clinicians electronically., Outcome Measures: The survey responses and prioritisation-both survey and workshop based., Results: There were 889 individually submitted questions from the initial survey, refined to 59 uncertainties across 32 themes. Eight additional uncertainties were added from published literature before prioritisation by 261 participants and the workshop allowed the final top 10 list to be finalised. The top 10 has so far contributed to the award of over £3.8 million of competitively awarded funding., Conclusions: The Common Conditions in the Hand and Wrist Priority Setting Partnership identified important research questions and has allowed research funders to identify grant applications which are important to both patients and clinicians., Competing Interests: Competing interests: This work was funded by the British Society for Surgery of the Hand. AK, AJ, GG, DF, TD and RWT are consultant hand surgeons and members of the British Society for Surgery of the Hand. All are active in clinical and non-clinical research.
