ObjectivesTo examine the accuracy and impact of artificial intelligence (AI) software assistance in lung cancer screening using CT.MethodsA systematic review of CE-marked, AI-based software for automated detection and analysis of nodules in CT lung cancer screening was conducted. Multiple databases including Medline, Embase and Cochrane CENTRAL were searched from 2012 to March 2023. Primary research reporting test accuracy or impact on reading time or clinical management was included. QUADAS-2 and QUADAS-C were used to assess risk of bias. We undertook narrative synthesis.ResultsEleven studies evaluating six different AI-based software and reporting on 19 770 patients were eligible. All were at high risk of bias with multiple applicability concerns. Compared with unaided reading, AI-assisted reading was faster and generally improved sensitivity (+5% to +20% for detecting/categorising actionable nodules; +3% to +15% for detecting/categorising malignant nodules), with lower specificity (−7% to −3% for correctly detecting/categorising people without actionable nodules; −8% to −6% for correctly detecting/categorising people without malignant nodules). AI assistance tended to increase the proportion of nodules allocated to higher risk categories. Assuming 0.5% cancer prevalence, these results would translate into additional 150–750 cancers detected per million people attending screening but lead to an additional 59 700 to 79 600 people attending screening without cancer receiving unnecessary CT surveillance.ConclusionsAI assistance in lung cancer screening may improve sensitivity but increases the number of false-positive results and unnecessary surveillance. Future research needs to increase the specificity of AI-assisted reading and minimise risk of bias and applicability concerns through improved study design.PROSPERO registration numberCRD42021298449.

Background Partnerships in public health form an important component of commissioning and implementing services, in England and internationally. In this research, we examine the views of staff involved in a City-wide health improvement programme which ran from 2009 to 2013 in England. We examine the practicalities of partnership work in community settings, and we describe some of barriers faced when implementing a large, multi-organisation health improvement programme. Methods Qualitative, semi-structured interviews were performed. Purposive sampling was used to identify potential participants in the programme: programme board of directors, programme and project managers and intervention managers. Interviews were conducted one-to-one. We conducted a thematic analysis using the ‘one sheet of paper’ technique. This involved analysing data deductively, moving from initial to axial coding, developing categories and then identifying emerging themes. Results Fifteen interviews were completed. Three themes were identified. The first theme reflects how poor communication approaches hindered the ability of partnerships to deliver their aims and objectives in a range of ways and for a range of reasons. Our second theme reflects how a lack of appropriate knowledge exchange hindered decision-making, affected trust and contributed to protectionist approaches to working. This lack of shared, and communicated, understanding of what type of knowledge is most appropriate and in which circumstance made meaningful knowledge exchange challenging for decision-making and partnership-working in the City-wide health improvement programme. Theme three demonstrates how perceptions about silos in partnership-working could be problematic, but silos themselves were at times beneficial to partnerships. This revealed a mismatch between rhetoric and a realistic understanding of what components of the programme were functional and which were more hindrance than help. Discussion There were high expectations placed on the concept of what partnership work was, or how it should be done. We found our themes to be interdependent, and reflective of the ‘dynamic fluid process’ discussed within the knowledge mobilisation literature. We contend that reframing normal and embedded processes of silos and silo-working already in use might ease resistance to some knowledge exchange processes and contribute to better long-term functioning of public health partnerships.

Background The perception and use of scientific evidence in orthopaedic surgical decision-making is variable, and there is considerable variation in practice. A previous conceptual framework described eight different drivers of orthopaedic surgical decision-making: formal codified and managerial knowledge, medical socialisation, cultural, normative and political influence, training and formal education, experiential factors, and individual patient and surgeon factors. This Qualitative Evidence Synthesis (QES) aims to refine the conceptual framework to understand how these drivers of decision-making are applied to orthopaedic surgical work in a dynamic and fluid way. Methods A QES explored how different types of knowledge and evidence inform decision-making to explore why there is so much variation in orthopaedic surgical work. Nine databases were systematically searched from 2014 to 2023. Screening was undertaken independently by two researchers. Data extraction and quality assessment were undertaken by one researcher and accuracy checked by another. Findings were mapped to the conceptual framework and expanded through thematic synthesis. Results Twenty-five studies were included. Our re-conceptualised framework of evidence-based orthopaedics portrays how surgeons undergo a constant process of medical brokering to make decisions. Routinely standardising, implementing and regulating surgical decision making presents a challenge when the decision-making process is in a constant state of flux. We found that surgeons constantly prioritise drivers of decision-making in a flexible and context-specific manner. We introduce the concept of socialisation in decision making, which describes “the socialisation of factors affecting decision-making. Socialisation is additive to surgeon identity and organisational capacity, which as explanatory linchpins act to mediate our understanding of how and why surgical decision-making varies. Our conceptual framework allows us to rationalise why formal codified knowledge, typically endorsed through clinical guidelines, consistently plays a limited role in orthopaedic decision-making. Conclusions We present a re-conceptualised framework for understanding what drives real world decision-making in orthopaedics. This framework highlights the dynamic and fluid way these drivers of decision-making are applied in orthopaedic surgical work. A shift in orthopaedics is required away from prioritising informal, experiential knowledge first to incorporating evidence-based sources of evidence as essential for decision-making. This paradigm shift, views decision-making as a complex intervention, that requires alternative approaches underpinned by multi-faceted, evidence-based implementation strategies to encourage evidence-based practice.

Background: The worldwide prevalence of paternal perinatal anxiety (PPA) ranges between 3.4% and 25.0% antenatally, and 2.4% and 51.0% postnatally. Experiencing PPA can adversely impact the individual, partners, and infants. Research concerning PPA is lagging and fragmented compared to research for new mothers. Objectives: To establish the effectiveness of prevention or treatment interventions for PPA in adults identifying as male. Data sources: We completed searches of Medline, EMBASE, PsycINFO and Web of Science from inception to 2 December 2021, as well as hand searches of references from relevant papers. Search selection and data extraction: Randomised controlled trials delivering prevention or treatment interventions and reporting anxiety outcomes for new/expectant fathers in the perinatal mental health period were included. Our review follows the PRISMA reporting guidelines. One reviewer independently screened 5170 titles/abstracts; second reviewers screened 50%. Two reviewers independently screened full text, extracted data, and conducted risk of bias assessments. Synthesis: Cochrane’s collaboration tool 2 was used to assess quality. Primarily results are synthesised narratively, a post-hoc sub-group analysis was completed on four studies using the same outcome measure. Main results: Twelve of the 5170 studies fulfilled the inclusion criteria. Studies used psychoeducational or practical skills interventions. Interventions mostly involved couple-dyads and three studies assessed PPA as a primary outcome. Included interventions were prevention-based; no treatment interventions were found. Father-only interventions consistently reported a significant reduction of PPA. Conclusions: Systematic searching yielded no treatment interventions, highlighting a substantial gap in the evidence base. Within a limited and heterogenous sample, no studies targeted diagnosed PPA. Evidence suggested father-focused interventions may be effective in preventing PPA, regardless of the intervention delivery mode or intervention content. However, consistency between study design and options within the field are lacking compared to interventions available for mothers.

Background The uptake and use of clinical guidelines is often insufficient to change clinical behaviour and reduce variation in practice. As a consequence of diverse organisational contexts, the simple provision of guidelines cannot ensure fidelity or guarantee their use when making decisions. Implementation research in surgery has focused on understanding what evidence exists for clinical practice decisions but limits understanding to the technical, educational and accessibility issues. This research aims to identify where, when and how evidence and knowledge are used in orthopaedic decision-making and how variation in these factors contributes to different approaches to implementation of clinical guidance in practice. Methods We used in-depth case studies to examine guideline implementation in real-life surgical practice. We conducted comparative case studies in three English National Health Service hospitals over a 12-month period. Each in-depth case study consisted of a mix of qualitative methods including interviews, observations and document analysis. Data included field notes from observations of day-to-day practice, 64 interviews with NHS surgeons and staff and the collection of 121 supplementary documents. Results Case studies identified 17 sources of knowledge and evidence which influenced clinical decisions in elective orthopaedic surgery. A comparative analysis across cases revealed that each hospital had distinct approaches to decision-making. Decision-making is described as occurring as a result of how 17 types of knowledge and evidence were privileged and of how they interacted and changed in context. Guideline implementation was contingent and mediated through four distinct contextual levels. Implementation could be assessed for individual surgeons, groups of surgeons or the organisation as a whole, but it could also differ between these levels. Differences in how evidence and knowledge were used contributed to variations in practice from guidelines. Conclusion A range of complex and competing sources of evidence and knowledge exists which influence the working practices of healthcare professionals. The dynamic selection, combination and use of each type of knowledge and evidence influence the implementation and use of clinical guidance in practice. Clinical guidelines are a fundamental part of practice, but represent only one type of evidence influencing clinical decisions. In the orthopaedic speciality, other distinct sources of evidence and knowledge are selected and used which impact on how guidelines are implemented. New approaches to guideline implementation need to appreciate and incorporate this diverse range of knowledge and evidence which influences clinical decisions and to take account of the changing contexts in which decisions are made.

ObjectivesImposter Phenomenon is characterised by persistent self-doubt despite objective success. It has been associated with anxiety, burnout and reduced job satisfaction. Little is known about imposter phenomenon’s presence and impact in Trauma and Orthopaedic surgery. This study aims to determine the prevalence and predictors of Imposter Phenomenon among UK orthopaedic surgeons, further mapping domains that affect leadership and professional development.DesignCross-sectional survey using the validated Clance Imposter Phenomenon Scale (CIPS).SettingThe survey was distributed to UK orthopaedic surgeons between 20 October 2023 and 28 February 2024 via Training Programme Directors and the British Orthopaedic Association.ParticipantsOrthopaedic trainees and consultant surgeons (n=441)Primary and secondary outcome measuresImposter Phenomenon severity measured using CIPS (mild: 41–60, moderate: 61–80 and severe: 81–100). Univariate and multivariate analyses identified predictors of this severity. Self-reported impact of Imposter Phenomenon assessed across personal and leadership domains.Results92% of respondents reported moderate to intense Imposter Phenomenon symptoms (mean CIPS=65.17). Trainees had significantly higher mean scores (70.64±13.85) compared with consultants (59.82±15.71). Female surgeons reported significantly higher mean scores (72.57±13.35) than male surgeons (61.19±15.74). Female gender, non-consultant training grade and time out of training were predictors of severity (p<0.01). 90% reported negative impacts, with 49% discouraged from applying for leadership roles and 45% experiencing hindered career progression.ConclusionThe Imposter Phenomenon is highly prevalent among UK orthopaedic surgeons; disproportionately affecting women, trainees and those taking career breaks. Imposter Phenomenon significantly impacts leadership aspirations and career development, potentially contributing to reduced diversity in surgical leadership. Targeted interventions addressing Imposter Phenomenon are needed to support equitable leadership development in Trauma and Orthopaedic surgery.

BackgroundChronic migraine can be a profoundly disabling disorder that may be treated with preventive medications. However, uncertainty remains as to which preventive medication is the most effective. We present a network meta-analysis to determine the effectiveness and rank of preventive drugs for chronic migraine in adults.MethodsWe identified, reviewed, and extracted data from randomised controlled trials (RCTs) of preventive drugs for chronic migraine with at least 200 participants. Data were analysed using network meta-analysis.FindingsWe included 12 RCTs of six medications (Eptinezumab, Erenumab, Fremanezumab, Galcanezumab, Onabotulinumtoxin A, and Topiramate) compared to placebo or each other. All drugs effectively reduced monthly headache and migraine days compared with placebo. The most effective drug for monthly headache days was Eptinezumab 300mg, with a mean difference of -2.46 days, 95% Credible Interval (CrI): -3.23 to -1.69. On the Surface Under the Cumulative Ranking Area (SUCRA) analysis, the probability that Eptinezumab 300mg was ranked highest was 0.82. For monthly migraine days, the most effective medication was Fremanezumab-monthly, with a mean difference: -2.77 days, 95% CrI: -3.36 to -2.17, and 0.98 probability of being ranked the highest. All included drugs, except Topiramate, improved headache-related quality of life. No eligible studies were identified for the other common preventive oral medications such as Amitriptyline, Candesartan, and Propranolol. The main reasons were that the studies did not define chronic migraine, were undertaken before the definition of chronic migraine, or were too small.InterpretationAll six medications were more effective than the placebo on monthly headache and migraine days. The absolute differences in the number of headache/migraine days are, at best, modest. No evidence was found to determine the relative effectiveness of the six included drugs with other oral preventive medications.RegistrationPROSPERO (number CRD42021265990).

IntroductionStillbirth and second trimester miscarriage have wide-reaching consequences for women, their partners and their families. There is currently little community-based care provision within the National Health Service for women and partners who have had a stillbirth or second trimester miscarriage. There is a research gap in the evidence to guide best practice. This review will seek to understand how, when and where this care is best delivered.Methods and analysisThe aim of this review is to identify the key elements of community-based care following a stillbirth or second trimester miscarriage. As this is a complex intervention, a realist approach will be used to establish for whom, how, when and where this care is best delivered. An initial programme theory will be constructed which will be tested against the available evidence and refined. A wide range of evidence including qualitative, quantitative, mixed-methods and experiential knowledge will be identified through secondary sources, extracted and synthesised to develop and refine the programme theory.Ethics and disseminationThis review will not require ethical approval as it does not involve primary data collection. The findings will be submitted for open-access publication to a peer-reviewed journal and disseminated to stakeholders.PROSPERO registration numberCRD42024587365.

Background Australia’s clinical trials sector is highly productive with continued sector investment needed to enhance research impact. Generating economic evidence alongside trials has the potential to facilitate the implementation of trial results into practice. Ascertaining the use of health economic evaluations alongside clinical trials can assist in determining whether clinical trials fully realize and operationalize their potential to change policy and practice. The aims of this study were to ascertain the uptake of health economic evaluations alongside Australian-led clinical trials and explore associations between uptake and trial characteristics. Methods This observational study comprised a descriptive analysis of clinical trials registries, a cross-sectional survey of Australian Clinical Trials Alliance (ACTA) networks, and a subgroup analysis of completed acute care trials. Descriptive analyses of trial registrations were conducted, with logistic regressions used to identify predictors of proposing and subsequently publishing a health economic evaluation alongside acute care trials. Results Few randomized Australian-led clinical trials (11% of 9251) and ACTA network trials (43% of 227) proposed a health economic evaluation. In the subgroup analysis, 22% of the 324 acute care trials and 53% of the 38 ACTA network acute care trials proposed a health economic evaluation. Acute care trials funded by government bodies were significantly more likely to propose and publish a health economic evaluation than those funded by hospitals, universities, and other funders, after adjusting for phase, registration year, primary sponsor type, and comparator. Conclusions Current uptake of health economic evaluations alongside Australian-led clinical trials is low, with uptake higher among the subset of ACTA network trials. This is despite economic evidence playing an increasingly prominent role in health system management, as well as rising health expenditure, limited budgets, and competing demands. There is significant opportunity to embed health economic evaluations alongside clinical trials, particularly phase 3 trials, to increase research outputs and optimize research translation. Investing in clinical trial networks that support funding for a health economist or a health economic evaluation may be an effective strategy to increase the uptake of health economic evaluations alongside trials.

A systematic review was conducted in order to explore the effectiveness of communication-skills training interventions in end-of-life care with noncancer acute-based healthcare staff. Articles were included if they (1) focused on communication-skills training in end-of-life/palliative care for noncancer acute-based staff and (2) reported an outcome related to behavior change with regard to communication. Sixteen online databases were searched, which resulted in 4,038 potential articles. Screening of titles left 393 articles that met the inclusion criteria. Abstracts (n = 346) and full-text articles (n = 47) were reviewed, leaving 10 papers that met the criteria for our review. All articles explored the effect of communication-skills training on aspects of staff behavior; one study measured the effect on self-efficacy, another explored the impact on knowledge and competence, and another measured comfort levels in discussing the end of life with patients/families. Seven studies measured a number of outcomes, including confidence, attitude, preparedness, stress, and communication skills. Few studies have focused on end-of-life communication-skills training in noncancer acute-based services. Those that do have report positive effects on staff behavior with regard to communication about the end of life with patients and families. The studies varied in terms of the population studied and the health services involved, and they scored only moderately or weakly on quality. It is a challenge to draw a definite conclusion about the effectiveness of training interventions in end-of-life communication because of this. However, the findings from our review demonstrate the potential effectiveness of a range of training interventions with healthcare professionals on confidence, attitude, self-efficacy, and communication skills. Further research is needed to fully explore the effectiveness of existing training interventions in this population, and evidence using objective measures is particularly needed. Ideally, randomized controlled trials or studies using control groups and longer follow-ups are needed to test the effectiveness of interventions.
