What is the volume, quality and characteristics of evidence relating to the effectiveness and cost-effectiveness of multi-disciplinary occupational health interventions aiming to improve work-related outcomes for employed adults? An evidence and gap map of systematic reviews.

Background: In the UK, tens of millions of working days are lost due to work-related ill health every year, costing billions of pounds. The role of Occupational Health (OH) services is vital in helping workers to maintain employment when they encounter injury or illness. OH providers traditionally rely on a clinical workforce to deliver these services, particularly doctors and nurses with OH qualifications. However, the increasing demand for OH services is unlikely to be met in the future using this traditional model, due to the declining number of OH-trained doctors and nurses in the UK. Multi-disciplinary models of OH delivery, including a more varied range of healthcare and non-healthcare professionals, could provide a way to meet this new demand for OH services. There is a need to identify collaborative models of OH service delivery and review their effectiveness on return-to work outcomes. There is an existing pool of systematic review evidence evaluating workplace based, multi-disciplinary OH interventions, but it is difficult to identify which aspects of the content and/or delivery of these interventions may be associated with improved work-related outcomes. Objectives: The aim of this evidence and gap map (EGM) was to provide an overview of the systematic review evidence that evaluates the effectiveness and cost-effectiveness of multi-disciplinary OH interventions intending to improve work-related outcomes. Search Methods: In June 2021 we searched a selection of bibliographic databases and other academic literature resources covering a range of relevant disciplines, including health care and business studies, to identify systematic review evidence from a variety of sectors of employment. We also searched Google Search and a selection of topically relevant websites and consulted with stakeholders to identify reports already known to them. Searches were updated in February 2023. Selection Criteria: Systematic reviews needed to be about adults (16 years or over) in employment, who have had absence from work for any medical reason. Interventions needed to be multi-disciplinary (including professionals from different backgrounds in clinical and non-clinical professions) and designed to support employees and employers to manage health conditions in the workplace and/or to help employees with health conditions retain and/or return to work following medical absence. Effectiveness needed to be measured in terms of return to work, work retention or measures of absence, or economic evaluation outcomes. These criteria were applied to the title and abstract and full text of each systematic review independently by two reviewers, with disagreements resolved through discussion. We awarded each systematic review a rating of 'High', 'Medium' or 'Low' relevance to indicate the extent to which the populations, interventions and their contexts synthesised within the review were consistent with our research question. We also recorded the number of primary studies included within each of the 'High' and 'Medium' reviews that were relevant to research question using the same screening process applied at review level. Data Collection and Analysis: Summary data for each eligible review was extracted. The quality of the systematic reviews, rated as 'High' or 'Medium' relevance following full text screening, was appraised using the AMSTAR-2 quality appraisal tool. All data were extracted by one reviewer and checked by a second, with disagreements being settled through discussion. Summary data for all eligible systematic reviews were tabulated and described narratively. The data extracted from reviews of 'High' and 'Medium' relevance was imported into EPPI-Mapper software to create an EGM. Stakeholder Involvement: We worked alongside commissioners and policy makers from the Department of Health and Social Care (DHSC) and Department of Work and Pensions (DWP), OH personnel, and people with lived experience of accessing OH services themselves and/or supporting employees to access OH services. Individuals contributed to decision making at all stages of the project. This ensured our EGM reflects the needs of individuals who will use it. Main Results: We identified 98 systematic reviews that contained relevant interventions, which involved a variety of professionals and workplaces, and which measured effectiveness in terms of return to work (RTW). Of these, we focused on the 30 reviews where the population and intervention characteristics within the systematic reviews were considered to be of high or medium relevance to our research questions. The 30 reviews were of varying quality, split evenly between High/Moderate quality and Low/Critically-Low quality ratings. We did not identify any relevant systematic review evidence on any other work-related outcome of interest. Interventions were heterogenous, both within and across included systematic reviews. The EGM is structured according to the health condition experienced by participants, and the effectiveness of the interventions being evaluated, as reported within the included systematic reviews. It is possible to view (i) the quality and quantity of systematic review evidence for a given health condition, (ii) how review authors assessed the effectiveness or cost-effectiveness of the interventions evaluated. The EGM also details the primary studies relevant to our research aim included within each review. Authors' Conclusions: This EGM map highlights the array of systematic review evidence that exists in relation to the effectiveness or cost-effectiveness of multi-disciplinary, workplace-based OH interventions in supporting RTW. This evidence will allow policy makers and commissioners of services to determine which OH interventions may be most useful for supporting different population groups in different contexts. OH professionals may find the content of the EGM useful in identifying systematic review evidence to support their practice. The EGM also identifies where systematic review evidence in this area is lacking, or where existing evidence is of poor quality. These may represent areas where it may be particularly useful to conduct further systematic reviews.

Further Validation of Comfortable Print Size as a Parameter for Clinical Low-Vision Assessment.

Purpose: Comfortable print size (CfPS) has been proposed as a clinical alternative to deriving critical print size (CPS) in the assessment of reading function of vision-impaired patients. This study aimed to assess the repeatability of CfPS and to compare assessment duration and values to CPS measures and acuity reserves. Methods: Thirty-four adults with vision impairment had their reading function assessed. Two assessments of CfPS were made by asking, "What is the smallest print size that you would find comfortable using?" Reading parameters including CPS were determined using the MNREAD card chart and MNREAD app. Results: CfPS was quicker to assess (mean ± SD, 144 ± 77 seconds) than the MNREAD card (231 ± 177 seconds) or app (285 ± 43 seconds). Within-session repeatability of CfPS showed no significant bias or variation across the functional range and limits of agreement (LoA) of ±0.09 logMAR. CfPS values were 0.10 logMAR larger than card CPS values, but no different from app CPS values, with LoA of ±0.43 to 0.45 logMAR. Acuity reserve (comparing CfPS to card reading acuity) was 1.9:1 on average, with a maximum of 5.0:1. Conclusions: CfPS offers a quick, repeatable, and individualized clinical measure of the print size required for sustained reading that reflects CPS values obtained by more traditional measures. Translational Relevance: CfPS is an appropriate clinical measure of reading function to use in determining the magnification requirements of vision impaired patients for sustained reading tasks.

Not as Clear Online? Active Visualization of How PrEP Works in the Body Improves Knowledge But Doesn't Change Behavior.

Active visualization, the use of dynamic representation of internal processes, is associated with increased knowledge and adherence to ART among people living with HIV. The current pilot intervention study tested the effectiveness of an online visualization for HIV prevention among 146 at-risk youth. Youth were randomized to a standard PrEP briefing or an online visualization. PrEP knowledge, attitudes, and uptake were self-reported at baseline and 3-months. Knowledge of PrEP increased, but there were no changes in preferences or uptake. Active visualization delivered online may be a useful educational tool for PrEP but not for shifting youth's uptake.

Representation of Women in Internal Medicine Specialties in North America, the United Kingdom, and Australasia: Cardiology's Outlier Status and the Importance of Diversity.

Decades of research demonstrate the value of workplace diversity. Reports from individual countries show that women are underrepresented in internal medicine workforces. However, large pooled international studies are not available. This study investigates the current representation of women in the internal medicine workforce internationally and identifies specialties in which underrepresentation is evident. Peer-reviewed studies, government reports, and medical association reports were used to determine proportions of specialists and doctors training in internal medical specialties and in comparator surgical specialties. Data were available from Australia, Canada, England, New Zealand, the United States, Wales, Scotland, and Northern Ireland. A total of 380,263 doctors were studied, including 268,822 practicing specialist physicians (also known as attendings or consultants) and 53,226 doctors in internal medicine specialty training programs (also known as residents, fellows, advanced trainees, or specialist registrar trainees). Among practicing physician specialists, the rate of representation of women was 35% (95,195/268,822, p <0.001). Among trainees, the rate of representation of women was 43% (22,728/53,226, p <0.001). Among physician specialties evaluated, cardiology (15%, 4,152 of 27,328), gastroenterology (20%, 3,765 of 18,893), and respiratory/critical care (24%, 5,255 of 21,870) had the lowest representations of women compared with men (p <0.001 for all). Cardiology and particularly the subspecialty of interventional cardiology were clear outliers as the internal medicine specialties with the lowest representation of women at practicing specialist and trainee levels. In conclusion, this study is the largest international study of women in internal medicine specialties. It found that cardiology, gastroenterology, and respiratory/critical care specialties have the most substantial underrepresentation of women. These data are a global call to action to establish more successful strategies to provide a diverse and representative cardiology workforce.

COVID-19 prevention behaviors, trust, and intent to vaccinate among youth at risk for HIV.

The current study examines COVID-19 prevention behaviors and vaccine intentions among 83 youth at high risk for HIV. Most youth self-identified as Latinx (52%), cisgender men (84%), and homosexual (66%). Youth self-reported COVID-19 prevention behaviors and intentions to vaccinate. Participants reported wearing face masks, washing hands, and staying six feet apart, but fewer reported leaving home only for essential needs. About one-third reported that they would not get a vaccine, and lack of trust in their doctors and the government were significantly associated with non-intention. To improve efforts towards herd immunity, interventions to improve health messaging from trusted sources for at-risk youth may be necessary to achieve higher vaccine uptake.

Under-representation of Women as Proceduralists and Patients in TAVR and TMVr Procedures: Data, Implications and Proposed Solutions.

Women are under-represented among transcatheter aortic valve replacement (TAVR) and transcatheter mitral valve repair (TMVr) operators. This review assesses the representation of women as patients and as proceduralists and trial authors in major structural interventions. Women are under-represented as proceduralists in structural interventions: only 2% of TAVR operators and 1% of TMVr operators are women. Only 1.5% of authors in landmark clinical TAVR and TMVr trials are interventional cardiologists who are women (4/260). Significant under-representation and under-enrolment of women in landmark TAVR trials is evident: the calculated participation-to-prevalence ratio (PPR) is 0.73, and in TMVr trials, the PPR is 0.69. Under-representation of women is also evident in registry data (PPR = 0.84 for TAVR registries and for TMVr registries). In structural interventional cardiology, women are under-represented as proceduralists, trial participants and patients. This under-representation has the potential to affect the recruitment of women to randomised trials, subsequent guideline recommendations, selection for treatment, patient outcomes and sex-specific data analysis.

Endorsement of clinical practice guidelines: Criteria from the College of Family Physicians of Canada.

OBJECTIVE: To refine the process for endorsement of guidelines and establish the expectations of the College of Family Physicians of Canada (CFPC) regarding the quality and relevance of clinical practice guidelines targeting family physicians and their patients. COMPOSITION OF THE COMMITTEE: Initially, a group of 6 CFPC staff and selected College members reviewed the previous process for endorsement with the aim of providing a new direction, if needed. The work was then assumed by the Guideline and Knowledge Translation Expert Working Group, a purposefully selected group of 9 family physicians from across Canada with expertise in research, evidence, guidelines, knowledge translation, and continuing professional development and education. METHODS: The initial task force reviewed the endorsement process and identified areas for improvement. A draft new process and core criteria for high-quality guidelines were developed. This was approved by the CFPC board. A Guideline and Knowledge Translation Expert Working Group was then formed to further refine the process and the criteria. Multiple resources were used to inform the criteria. The Guideline and Knowledge Translation Expert Working Group will manage the endorsement process of external submitted guidelines, as well as provide high-level guidance to the CFPC regarding in-house guidelines and continuing professional development content. REPORT: This article provides the expectations of the CFPC regarding clinical practice guidelines and describes in detail the process and criteria for endorsement. Key principles include family physician involvement and guideline funding unlikely to introduce bias, with most criteria falling under 4 themed areas: relation to family medicine, CFPC values, patient engagement and decision making, and scientific rigour. The Guideline and Knowledge Translation Expert Working Group will report to the CFPC board at least once a year. It is hoped that this fully transparent process and these criteria will help advance the quality and standards of clinical practice guideline production in Canada. CONCLUSION: A comprehensive but reasonable list has been provided that reflects the best standards and recommendations and is consistent with the CFPC's values while recognizing the landscape of guideline development for its national partners and colleagues. As with all processes, careful consideration and evaluation will be essential.

Validation des lignes directrices de pratique clinique: Critères du Collège des médecins de famille du Canada.

OBJECTIF: Parfaire le processus de validation des lignes directrices et établir les attentes du Collège des médecins de famille du Canada (CMFC) quant à la qualité et à la pertinence des lignes directrices de pratique clinique à l'intention des médecins de famille et de leurs patients. COMPOSITION DU COMITÉ: Au départ, un groupe de 6 personnes, employés et membres choisis du CMFC, ont révisé le précédent processus de validation dans le but de lui donner une nouvelle orientation, au besoin. Le Groupe de travail d'experts sur les lignes directrices et le transfert des connaissances a ensuite pris le relais; ce groupe est composé de 9 médecins de famille sélectionnés avec soin partout au Canada qui sont expérimentés dans les domaines de la recherche, des données probantes, des lignes directrices, du transfert des connaissances, ainsi que du perfectionnement professionnel continu et de l'éducation. MÉTHODOLOGIE: Le groupe de travail initial s'est penché sur le processus de validation et a relevé les domaines pouvant être améliorés. L'ébauche d'un nouveau processus et de critères fondamentaux pour des lignes directrices de bonne qualité a été rédigée et approuvée par le Conseil d'administration du CMFC. Un Groupe de travail d'experts sur les lignes directrices et le transfert des connaissances a ensuite été formé pour peaufiner davantage le processus et les critères. Les critères s'appuient sur plusieurs ressources. Le Groupe de travail d'experts sur les lignes directrices et le transfert des connaissances aura la responsabilité de gérer le processus de validation des lignes directrices externes soumises, ainsi que de fournir au CMFC des conseils de haut niveau sur les lignes directrices internes et le contenu du perfectionnement professionnel continu. RAPPORT: Cet article présente les attentes du CMFC en matière de lignes directrices de pratique clinique, et décrit en détail le processus et les critères de validation. Les principes fondamentaux sont la participation des médecins de famille et le financement des lignes directrices qui est peu susceptible d'introduire un biais, et la plupart des critères s'inscrivent sous 4 thèmes : la relation avec la médecine familiale; les valeurs du CMFC; l'engagement et la prise de décision des patients; et la rigueur scientifique. Le Groupe de travail d'experts sur les lignes directrices et le transfert des connaissances présentera ses résultats au Conseil d'administration du CMFC au moins une fois l'an. L'on souhaite que ce processus complètement transparent et ces critères fassent progresser la qualité et les normes qui régissent la production des lignes directrices de pratique clinique au Canada. CONCLUSION: Une liste exhaustive, mais raisonnable, reflète les meilleures normes et recommandations, et respecte les valeurs du CMFC tout en reconnaissant le contexte de rédaction des lignes directrices pour ses partenaires et ses collègues à l'échelle nationale. Comme c'est le cas pour tous les processus, l'examen et l'évaluation approfondis seront essentiels.

A qualitative study of organisational response to national quality standards for 7-day services in English hospitals.

BACKGROUND: National standards are commonly used as an improvement strategy in healthcare, but organisations may respond in diverse and sometimes negative ways to external quality demands. This paper describes how a sample of NHS hospital trusts in England responded to the introduction of national standards for 7-day services (7DS), from an organisational behaviour perspective. METHODS: We conducted 43 semi-structured interviews with executive/director level and clinical staff, in eight NHS trusts that varied in size, location, and levels of specialist staffing at weekends. We explored approaches to implementing standards locally, and the impact of organisational culture and local context on organisational response. RESULTS: Senior staff in the majority of trusts described a focus on hitting targets and achieving compliance with the standards. Compliance-based responses were associated with a hierarchical organisational culture and focus on external performance. In a minority of trusts senior staff described mobilising commitment-based strategies. In these trusts senior staff reframed the external standards in terms of organisational values, and used co-operative strategies for achieving change. Trusts that took a commitment-based approach tended to be described as having a developmental organisational culture and a history of higher performance across the board. Audit data on 7DS showed improvement against standards for most trusts, but commitment-focused trusts were less likely to demonstrate improvements on the 7DS audit. The ability of trusts to respond to external standards was limited when they were under pressure due to a history of overall poor performance or resource limitations. CONCLUSIONS: National standards and audit for service-level improvement generate different types of response in different local settings. Approaches to driving improvement nationally need to be accompanied by resources and tailored support for improvement, taking into account local context and organisational culture.

No evidence synthesis about me without me: Involving young people in the conduct and dissemination of a complex evidence synthesis.

OBJECTIVES: To describe and reflect on the methods and influence of involvement of young people with lived experience within a complex evidence synthesis. STUDY DESIGN AND SETTING: Linked syntheses of quantitative and qualitative systematic reviews of evidence about interventions to improve the mental health of children and young people (CYP) with long-term physical conditions (LTCs). METHODS: Involvement was led by an experienced patient and public involvement in research lead. Young people with long-term physical conditions and mental health issues were invited to join a study-specific Children and Young People's Advisory Group (CYPAG). The CYPAG met face to face on four occasions during the project with individuals continuing to contribute to dissemination following report submission. RESULTS: Eight young people joined the CYPAG. Their views and experiences informed (a) a systematic review evaluating the effectiveness of interventions intended to improve the mental health of CYP with LTCs, (b) a systematic review exploring the experiences of interventions intended to improve the mental well-being of CYP with LTCs and (c) an overarching synthesis. The CYPAG greatly contributed to the team's understanding and appreciation of the wider context of the research. The young people found the experience of involvement empowering and felt they would use the knowledge they had gained about the research process in the future. CONCLUSION: Creating an environment that enabled meaningful engagement between the research team and the CYPAG had a beneficial influence on the young people themselves, as well as on the review process and the interpretation, presentation and dissemination of findings.

Changes in mammography screening in Ontario and Alberta following national guideline dissemination: an interrupted time series analysis.

Background: In November 2011, the Canadian Task Force on Preventive Health Care released guidelines for screening women at average breast cancer risk. Weak recommendations (framed using GRADE methodology) were made for screening women aged 50 to 74 years every two to three years, and for not screening women aged 40 to 49 years. Methods: We conducted an interrupted time series analysis using administrative data to examine bilateral mammography use before and after a release of a national breast screening guideline. Women aged 40 to 74 years living in Ontario or Alberta from 30th November 2008 to 30th November 2014 were included. Strata included age, region of residence, neighbourhood income quintile, immigration status, and education level. Results: In both provinces, mammography use rates were lower in the post-intervention period (527 vs. 556 and 428 vs. 465/1000 women in Ontario and Alberta, respectively). In Ontario, mammography trends decreased following guideline release to align with recommendations for women aged 40 to 74 (decrease of 2.21/1000 women, SE 0.26/1000, p<0.0001). In Alberta, mammography trends decreased for women aged 40 to 49 years (3/1000 women, SE 0.32, p<0.001) and 50 to 69 (2.9/1000 women, SE 0.79, p<0.001), but did not change for women aged 70 to 74 (0.7/1000 women, SE 1.23, p=0.553). In both provinces, trends in mammography use rates were sustained for up to three years after guideline release. Conclusions: We observed a decrease in screening for women aged 40-49. Additional research to explore whether shared decision making was used to optimize guideline-concordant screening for women aged 50-74 is needed.

Prenatal Care Outcomes in Women with Substance Use Disorders: A Retrospective Cohort Study.

OBJECTIVE: This study sought to examine and compare the characteristics and prenatal care and pregnancy outcomes of women with and without substance use disorder (SUD). It also examined whether there were differences in prenatal care and pregnancy outcomes within the population of substance-using women based on the stability of their SUD during pregnancy. METHODS: This retrospective cohort study involved pregnant women with and without SUD who accessed care through the Maternity Centre of Hamilton between 2015 and 2017. Cases and controls were matched 1:1 for gravidity, parity, ethnicity, smoking status, and postal code. RESULTS: Fifty-five pregnant women with SUD were identified and matched to 55 pregnant women without SUD. When analyzed by stability of substance use, women with stable SUD had similar outcomes to those of women without SUD. Women with unstable SUD received the poorest prenatal care and were more likely to have their infants removed from their care. There was significant movement towards stability of maternal substance use over the course of pregnancy in our integrated prenatal and addiction care model. CONCLUSION: Women with unstable SUD had poorer prenatal care and higher rates of custody loss than those with stable substance use disorders or those without substance use disorders. The disparate outcomes among women with unstable SUD may indicate a need to identify patients requiring greater support at entry into prenatal care and to target services accordingly. This integrated prenatal and addiction care model was effective in reducing maternal substance use in pregnancy.

Assessing Unperceived Learning Needs in Continuing Medical Education for Primary Care Physicians: A Scoping Review.

INTRODUCTION: Assessing needs before developing continuing medical education/continuing professional development (CME/CPD) programs is a crucial step in the education process. A previous systematic literature review described a lack of objective evaluation for learning needs assessments in primary care physicians. This scoping review updates the literature on uses of objective evaluations to assess physicians' unperceived learning needs in CME/CPD. Identifying and understanding these approaches can inform the development of educational programs that are relevant to clinical practice and patient care. The study objectives were to (1) scope the literature since the last systematic review published in 1999; (2) conduct a comprehensive search for studies and reports that explore innovative tools and approaches to identify physicians' unperceived learning needs; (3) summarize, compare, and classify the identified approaches; and (4) map any gaps in the literature to identify future areas of research. METHODS: A scoping review was used to "map" the literature on current knowledge regarding approaches to unperceived needs assessment using conceptual frameworks for planning and assessing CME/CPD activities. RESULTS: Two prominent gaps were identified: (1) performance-based assessment strategies are highly recommended in nonresearch articles yet have low levels of implementation in published studies and (2) analysis of secondary data through patient input or environmental scanning is emphasized in grey literature implementation strategies more so than in peer-reviewed theoretical and research articles. DISCUSSION: Future evaluations should continue to incorporate multiple strategies and focus on making unperceived needs assessments actionable by describing strategies for resource management.

Dual-Energy CT Pulmonary Angiography (DECTPA) Quantifies Vasculopathy in Severe COVID-19 Pneumonia.

BACKGROUND: The role of dual energy computed tomographic pulmonary angiography (DECTPA) in revealing vasculopathy in coronavirus disease 2019 (COVID-19) has not been fully explored. PURPOSE: To evaluate the relationship between DECTPA and disease duration, right ventricular dysfunction (RVD), lung compliance, D-dimer and obstruction index in COVID-19 pneumonia. MATERIALS AND METHODS: This institutional review board approved this retrospective study, and waived the informed consent requirement. Between March-May 2020, 27 consecutive ventilated patients with severe COVID-19 pneumonia underwent DECTPA to diagnose pulmonary thrombus (PT); 11 underwent surveillance DECTPA 14 ±11.6 days later. Qualitative and quantitative analysis of perfused blood volume (PBV) maps recorded: i) perfusion defect 'pattern' (wedge-shaped, mottled or amorphous), ii) presence of PT and CT obstruction index (CTOI) and iii) PBV relative to pulmonary artery enhancement (PBV/PAenh); PBV/PAenh was also compared with seven healthy volunteers and correlated with D-Dimer and CTOI. RESULTS: Amorphous (n=21), mottled (n=4), and wedge-shaped (n=2) perfusion defects were observed (M=20; mean age=56 ±8.7 years). Mean extent of perfusion defects=36.1%±17.2. Acute PT was present in 11/27(40.7%) patients. Only wedge-shaped defects corresponded with PT (2/27, 7.4%). Mean CTOI was 2.6±5.4 out of 40. PBV/PAenh (18.2 ±4.2%) was lower than in healthy volunteers (27 ±13.9%, p = 0.002). PBV/PAenh correlated with disease duration (ß = 0.13, p = 0.04), and inversely correlated with RVD (ß = -7.2, p = 0.001), persisting after controlling for confounders. There were no linkages between PBV/PAenh and D-dimer or CTOI. CONCLUSION: Perfusion defects and decreased PBV/PAenh are prevalent in severe COVID-19 pneumonia. PBV/PAenh correlates with disease duration and inversely correlates with RVD. PBV/PAenh may be an important marker of vasculopathy in severe COVID-19 pneumonia even in the absence of arterial thrombus.

Gender equity within medical specialties of Australia and New Zealand: cardiology's outlier status.

BACKGROUND: Gender disparity remains a prominent medical workforce issue, extending beyond surgical specialties with low proportions of female doctors. AIMS: To examine female representation within Australia and New Zealand (NZ) among physician specialties and certain comparator surgical specialties with a focus on cardiology as an outlier of workforce gender equality. METHODS: Data of practising medical specialists, new consultants and trainees were sought from the Australian Health Practitioner Regulation Agency, the Medical Council of NZ and the Royal Australasian College of Surgeons (2015-2017). The stratified data pertaining to interventional cardiologists were obtained through direct contact with individual hospitals (from 2017 to 2018) and derived from state-based cardiac registries. RESULTS: In Australia and NZ, there were fewer female practising adult medicine physician consultants (n = 8956, 32%, P < 0.001), with gender disparities seen across most physician specialties. Cardiology (15%) was the only physician specialty with <20% representation; gastroenterology (23%), neurology (27%) and respiratory medicine (29%) had <30% female representation at the consultant level. The rates of cardiology (15%) and interventional cardiology (5%) were similar to general surgery (15%) and orthopaedics (4%). Although more than half of physician trainees are female, and most physician specialties are approaching or have equal gender ratios at the trainee level, cardiology (23%) and interventional cardiology (9%) remain significantly underrepresented. CONCLUSIONS: Cardiology is the only physician specialty with <20% female consultants, and this disparity is reflected throughout every stage of the cardiology training programme. Increased awareness and proactive strategies are needed to improve gender disparity within this underrepresented medical specialty.

Factors contributing to radiation dose for patients and operators during diagnostic cardiac angiography.

INTRODUCTION: Diagnostic coronary angiography (CA) uses ionising radiation with relatively high doses, which impact on both patients and staff. This study sought to identify which patient and procedural factors impact patient and operator dose the most during CA. METHODS: Patient and procedure related variables impacting on Kerma area product (PKA ) and operator dose (OD) were collected for 16 months. Procedures were separated into 10 different procedure categories. PKA was used for patient dose and OD was measured with an instantly downloadable dosimeter (IDD) - downloaded at the end of each procedure. High and low radiation dose was defined by binary variables based on the 75th percentile of the continuous measures. Univariate and multivariate regression were used to identify predictors. RESULTS: Of 3860 patients included, the IDD was worn for 2591 (61.7%). Obesity (BMI > 30 compared to BMI < 25) was the strongest predictor for both a PKA (odds ratio (OR) = 19.1 (95% CI 13.5-26.9) P < 0.001) and OD (OR = 3.3 (2.4-4.4) P < 0.001) above the 75th percentile. Male gender, biplane imaging, the X-ray unit used, operator experience and procedure type also predicted a high PKA . Radial access, male gender, biplane imaging and procedure type also predicted a high OD. CONCLUSION: Radiation dose during CA is multifactorial and is dependent on patient and procedure related variables. Many factors impact on both PKA and OD but obesity is the strongest predictor for both patients and operators to receive a high radiation dose.
