Purpose: Delivering fair and reliable summative assessments in medical education assumes examiner decision making is devoid of bias. We investigated whether candidate racial appearances influenced examiner ratings in undergraduate clinical exams. Methods: We used an internet-based design. Examiners watched a randomised set of six videos of three different white candidates and three different non-white (Asian, black and Chinese) candidates taking a clinical history at either fail, borderline or pass grades. We compared the median and interquartile range (IQR) of the paired difference between scores for the white and non-white candidates at each performance grade and tested for statistical significance. Results1: 60 Examiners participated. At the fail grade, the black and Chinese candidates scored lower than the white candidate, with median paired differences of -2.5 and -1 respectively (both p < 0.001). At the borderline grade, the black and Chinese candidates scored higher than the white candidate, with median paired differences of +2 and +3, respectively (both p < 0.001). At the passing grade, the Asian candidate scored lower than the white candidate (median paired difference -1, p < 0.001). Conclusion: The racial appearance of candidates appeared to influence the scores awarded by examiners, but not in a uniform manner.

Background: This study reports the detailed management and outcomes of women treated with Primary Endocrine Therapy (PET) in a large prospective UK cohort of older women (≥70) with breast cancer. Methods: This was an unplanned secondary analysis of a prospective, multicentre, observational study (The Age Gap study). Data were collected at baseline and regular intervals on patient, tumour and treatment characteristics with tumour RECIST response category recorded. Direct study follow-up was 24 months with longer-term survival data obtained from the UK cancer registry. Results: The Age Gap study recruited 3316 women across 56 breast units. Primary endocrine therapy (PET) was initiated for 505/3316 (15 %) women; median age was 84 (IQR 79–88) with median follow-up 41.9 months (IQR 27–60). Death occurred in 205/505(40.6 %) patients, 160/205; 78 % non- Breast Cancer related, 45/205; 21.9 % Breast Cancer related. Multivariate analysis identified older age (HR-1.055(95 % Confidence Interval: 1.029–1.084); P < 0.001) and higher Charlson Index (HR-1.166 (1.086–1.252); P < 0.001) as risk factors for all-cause mortality, but conversion to surgery (HR-0.372(0.152–0.914); P = 0.031) was protective. Grade 3 cancer (G1 vs G3 HR-0.28 (0.094–0.829); P = 0.022 & G2 vs G3 HR-0.469 (0.226–0.973); P = 0.042), axillary positivity (axilla positivity HR-2.548 (1.321–4.816); P = 0.005) and change of endocrine therapy (HR-3.010 (1.532–5.913); P = 0.001) were associated with worse breast cancer specific survival (BCSS). RECIST category was not significantly associated with either overall survival or BCSS (P > 0.05). Conclusion: Early disease response and change of endocrine therapy are not significantly associated with overall survival, conversion to surgery is linked to improved outcome. Prognosis is largely determined by age and comorbidity in older women treated with PET.

Abstract Background Automated Item Generation (AIG) uses computer software to create multiple items from a single question model. There is currently a lack of data looking at whether item variants to a single question result in differences in student performance or human-derived standard setting. The purpose of this study was to use 50 Multiple Choice Questions (MCQs) as models to create four distinct tests which would be standard set and given to final year UK medical students, and then to compare the performance and standard setting data for each. Methods Pre-existing questions from the UK Medical Schools Council (MSC) Assessment Alliance item bank, created using traditional item writing techniques, were used to generate four ‘isomorphic’ 50-item MCQ tests using AIG software. Isomorphic questions use the same question template with minor alterations to test the same learning outcome. All UK medical schools were invited to deliver one of the four papers as an online formative assessment for their final year students. Each test was standard set using a modified Angoff method. Thematic analysis was conducted for item variants with high and low levels of variance in facility (for student performance) and average scores (for standard setting). Results Two thousand two hundred eighteen students from 12 UK medical schools participated, with each school using one of the four papers. The average facility of the four papers ranged from 0.55–0.61, and the cut score ranged from 0.58–0.61. Twenty item models had a facility difference > 0.15 and 10 item models had a difference in standard setting of > 0.1. Variation in parameters that could alter clinical reasoning strategies had the greatest impact on item facility. Conclusions Item facility varied to a greater extent than the standard set. This difference may relate to variants causing greater disruption of clinical reasoning strategies in novice learners compared to experts, but is confounded by the possibility that the performance differences may be explained at school level and therefore warrants further study.

Abstract The 19p13.1 breast cancer susceptibility locus is a modifier of breast cancer risk in BRCA1 mutation carriers and is also associated with the risk of ovarian cancer. Here, we investigated 19p13.1 variation and risk of breast cancer subtypes, defined by estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) status, using 48,869 breast cancer cases and 49,787 controls from the Breast Cancer Association Consortium (BCAC). Variants from 19p13.1 were not associated with breast cancer overall or with ER-positive breast cancer but were significantly associated with ER-negative breast cancer risk [rs8170 OR, 1.10; 95% confidence interval (CI), 1.05–1.15; P = 3.49 × 10−5] and triple-negative (ER-, PR-, and HER2-negative) breast cancer (rs8170: OR, 1.22; 95% CI, 1.13–1.31; P = 2.22 × 10−7). However, rs8170 was no longer associated with ER-negative breast cancer risk when triple-negative cases were excluded (OR, 0.98; 95% CI, 0.89–1.07; P = 0.62). In addition, a combined analysis of triple-negative cases from BCAC and the Triple Negative Breast Cancer Consortium (TNBCC; N = 3,566) identified a genome-wide significant association between rs8170 and triple-negative breast cancer risk (OR, 1.25; 95% CI, 1.18–1.33; P = 3.31 × 10−13]. Thus, 19p13.1 is the first triple-negative–specific breast cancer risk locus and the first locus specific to a histologic subtype defined by ER, PR, and HER2 to be identified. These findings provide convincing evidence that genetic susceptibility to breast cancer varies by tumor subtype and that triple-negative tumors and other subtypes likely arise through distinct etiologic pathways.

Background: POSNOC is a UK-ANZ multicentre, non-inferiority, randomised trial comparing systemic therapy alone with systemic therapy plus Axillary Treatment (Axillary radiotherapy or ALND) for women with ≤2 macrometastases at SNB. The primary outcome is axillary recurrence within 5 years. This paper describes screening, recruitment and compliance data. Methods: Sites were requested on a monthly basis to upload screening data and provide reasons for non-recruitment of eligible patients into the trial. Sites entered in the online database whether the patients were compliant with their randomisation allocation. Results: The study opened in July 2014 and completed target recruitment of 1900 women (24% of those screened) in July 2021, at 95 sites in the UK and 20 sites in Australia and New Zealand. The reason for non-enrolment was unknown in 1300 women. Of the remaining 4774 women with known reasons, who were screened but not randomised, the most common reasons for non-recruitment were due to either patients (n=2219, 46.5%) or their clinicians (n=782, 16.4%) favouring axillary treatment, or patients (n=490, 10.3%) or their clinicians (n=170, 3.6%) not wishing to have axillary treatment. Over the course of the study, there was an increase in the proportion of patients wanting axillary treatment and declining the trial (Mean % patients declined 2015 – 17.9%, 2021 – 39.1%). Mean number of participants recruited per site per month was 0.24 (SD 0.18) overall, 0.25 (SD 0.19) in the UK, and 0.19(SD 0.15) in ANZ. The mean was < 0.3 in 79 sites and >0.9 in only one site. Recruitment rate remained consistent throughout the study (mean 25.3 per month) except for during the first 6 months of recruitment (5.7) and during the COVID pandemic Apr-Sep 2020 (7.5). Of 89 (4.8%) participants non-compliant with allocation, n=45 (50.6%) received systemic therapy alone and n=44 (49.4%) received systemic therapy plus axillary treatment. There was no fluctuation in the direction of non-compliance during the study duration. There was increasing uptake of axillary radiotherapy to treat the axilla instead of ALND over the course of the study in patients receiving axillary treatment (Number who had ART of all who had axilla treatment2014-2017 - 248/454 (54.6 %); 2018-2021 – 315/449 (70.2%)). Conclusion: Recruitment and compliance with randomised allocation remained consistent over a seven-year period. POSNOC with in-built radiotherapy QA will provide definitive data on axillary management in patients undergoing mastectomy or BCS with ≤2 macrometastases on SNB.

Objectives Mitigating carbon footprint of products used in resource-intensive areas such as surgical operating rooms will be important in achieving net zero carbon healthcare. The aim of this study was to evaluate the carbon footprint of products used within five common operations, and to identify the biggest contributors (hotspots). Design A predominantly process-based carbon footprint analysis was conducted for products used in the five highest volume surgical operations performed in the National Health System in England. Setting The carbon footprint inventory was based on direct observation of 6–10 operations/type, conducted across three sites within one NHS Foundation Trust in England. Participants Patients undergoing primary elective carpal tunnel decompression, inguinal hernia repair, knee arthroplasty, laparoscopic cholecystectomy, tonsillectomy (March 2019 – January 2020). Main outcome measures We determined the carbon footprint of the products used in each of the five operations, alongside greatest contributors through analysis of individual products and of underpinning processes. Results The mean average carbon footprint of products used for carpal tunnel decompression was 12.0 kg CO 2 e (carbon dioxide equivalents); 11.7 kg CO 2 e for inguinal hernia repair; 85.5 kg CO 2 e for knee arthroplasty; 20.3 kg CO 2 e for laparoscopic cholecystectomy; and 7.5 kg CO 2 e for tonsillectomy. Across the five operations, 23% of product types were responsible for ≥80% of the operation carbon footprint. Products with greatest carbon contribution for each operation type were the single-use hand drape (carpal tunnel decompression), single-use surgical gown (inguinal hernia repair), bone cement mix (knee arthroplasty), single-use clip applier (laparoscopic cholecystectomy) and single-use table drape (tonsillectomy). Mean average contribution from production of single-use items was 54%, decontamination of reusables 20%, waste disposal of single-use items 8%, production of packaging for single-use items 6% and linen laundering 6%. Conclusions Change in practice and policy should be targeted towards those products making greatest contribution, and should include reducing single-use items and switching to reusables, alongside optimising processes for decontamination and waste disposal, modelled to reduce carbon footprint of these operations by 23%–42%.

Objectives: Despite NICE guidelines to 'treat people with invasive breast cancer, irrespective of age, with surgery and appropriate systemic therapy, rather than endocrine therapy alone', older patients receive differential treatment and experience worse outcomes. Research has evidenced the prevalence of ageism and identified the role of implicit bias in reflecting and potentially perpetuating disparities across society, including in healthcare. Yet age bias has rarely been considered as an explanatory factor in poorer outcomes for older breast cancer patients nor, consequentially, has removing age bias been considered as an approach to improving outcomes. Many organizations carry out bias training with the aim of reducing negative impacts from biased decision making, yet the few evaluations of these interventions have mostly seen small or negative effects. This study explores whether a novel intervention to address age bias leads to better quality decision making for the treatment of older women with breast cancer.Methods: An online study compared medical students' treatment recommendations for older breast cancer patients and the reasoning for their decision making before and after a novel bias training intervention. Thirty-one medical students participated in the study.Results: The results show that the bias training intervention led medical students to make better quality decisions for older breast cancer patients. The quality of decision making was measured by decreases in age-based decision making and increased efforts to include patients in decision making. These results suggest there is value in exploring whether if anti-bias training interventions could usefully be applied in other areas of practice where older patients experience poorer outcomes.Conclusions: This study evidences that bias training improves the quality of decision making by medical students in respect of older breast cancer patients. The study findings show promise that this novel approach to bias training might usefully be applied to all medical practitioners making treatment recommendations for older patients.

Abstract Background: Multiple genome-wide and candidate gene association studies have been conducted in search of common risk variants for breast cancer. Recent large meta analyses, consolidating evidence from these studies, have been consistent in highlighting the caspase-8 (CASP8) gene as important in this regard. To define a risk haplotype and map the CASP8 gene region with respect to underlying susceptibility variant/s, we screened four genes in the CASP8 region on 2q33-q34 for breast cancer risk. Methods: Two independent data sets from the United Kingdom and the United States, including 3,888 breast cancer cases and controls, were genotyped for 45 tagging single nucleotide polymorphisms (tSNP) in the expanded CASP8 region. SNP and haplotype association tests were carried out using Monte Carlo-based methods. Results: We identified a three-SNP haplotype across rs3834129, rs6723097, and rs3817578 that was significantly associated with breast cancer (P < 5 × 10−6), with a dominant risk ratio and 95% CI of 1.28 (1.21–1.35) and frequency of 0.29 in controls. Evidence for this risk haplotype was extremely consistent across the two study sites and also consistent with previous data. Conclusion: This three-SNP risk haplotype represents the best characterization so far of the chromosome upon which the susceptibility variant resides. Impact: Characterization of the risk haplotype provides a strong foundation for resequencing efforts to identify the underlying risk variant, which may prove useful for individual-level risk prediction, and provide novel insights into breast carcinogenesis.

BACKGROUND:The aim of this study was to estimate the carbon footprint and financial cost of decontaminating (steam sterilization) and packaging reusable surgical instruments, indicating how that burden might be reduced, enabling surgeons to drive action towards net-zero-carbon surgery. METHODS:Carbon footprints were estimated using activity data and prospective machine-loading audit data at a typical UK in-hospital sterilization unit, with instruments wrapped individually in flexible pouches, or prepared as sets housed in single-use tray wraps or reusable rigid containers. Modelling was used to determine the impact of alternative machine loading, opening instruments during the operation, streamlining sets, use of alternative energy sources for decontamination, and alternative waste streams. RESULTS:The carbon footprint of decontaminating and packaging instruments was lowest when instruments were part of sets (66-77 g CO2e per instrument), with a two- to three-fold increase when instruments were wrapped individually (189 g CO2e per instrument). Where 10 or fewer instruments were required for the operation, obtaining individually wrapped items was preferable to opening another set. The carbon footprint was determined significantly by machine loading and the number of instruments per machine slot. Carbon and financial costs increased with streamlining sets. High-temperature incineration of waste increased the carbon footprint of single-use packaging by 33-55 per cent, whereas recycling reduced this by 6-10 per cent. The absolute carbon footprint was dependent on the energy source used, but this did not alter the optimal processes to minimize that footprint. CONCLUSION:Carbon and financial savings can be made by preparing instruments as part of sets, integrating individually wrapped instruments into sets rather than streamlining them, efficient machine loading, and using low-carbon energy sources alongside recycling.

ObjectivesDespite NICE (2009; 2018) guidelines to treat breast cancer patients ‘irrespective of age’, older women experience differential treatment and worse outcomes beyond that which can be explained by patient health or patient choice. Research has evidenced the prevalence of ageism and identified the role of implicit bias in reflecting and perhaps perpetuating disparities across society, including in healthcare. Yet age bias has rarely been considered as an explanatory factor in poorer outcomes for older breast cancer patients.MethodsThis mixed methods study explored age bias amongst breast cancer HCPs through four components: 1) An implicit associations test (31 HCPs)2) A treatment recommendations questionnaire (46 HCPs).3) An attitudes about older patients questionnaire (31 HCPs).4) A treatment recommendations interview (20 HCPs).ResultsThis study showed that breast cancer HCPs held negative implicit associations towards older women; HCPs were less likely to recommend surgery for older patients; some HCPs held assumptions that older patients are more afraid, less willing and able to be involved in decision-making, and are less willing and able to cope with being informed of a poor treatment prognosis; and conditions which disproportionately affect older patients, such as dementia, are not always well understood by breast cancer HCPs.ConclusionsThese results indicate that there are elements of age bias present amongst breast cancer HCPs. The study's findings of age-based assumptions and a poorer understanding of conditions which disproportionately affect older patients align with patterns of differential treatment towards older breast cancer patients suggesting that age bias may be, at least in part, driving differential treatment.

Purpose The primary objective of this study was to evaluate the environmental impact and financial cost of repairing surgical scissors. Methods We used life cycle assessment (LCA) and life cycle cost analysis to estimate environmental impacts and financial cost of repairing surgical scissors. The functional unit was one use of a reusable surgical scissor (manufactured in Germany and used in the UK), and three baseline scenarios were compared: no repair, onsite (hospital), and offsite (external contract) repair. This ‘cradle-to-grave’ analysis included raw material extraction, manufacture of scissors and materials within primary and secondary packaging, transportation, decontamination, repair (where relevant), and waste disposal. Primary activity data was sourced from the instrument manufacturer, supplier, and from UK repair centres (both onsite and offsite), whilst the Ecoinvent database was used as a secondary data source for the manufacture of scissors. The World ReCiPe Midpoint and Endpoint Hierarchist method (Version 1.1) was used for environmental impact assessment. Scenario analysis was used to evaluate the impact of altering different assumptions, including number of uses, reducing number of repairs, increasing distance to offsite repair centre, and alternative electricity sources and waste handling processes. Life cycle cost analysis was calculated based on purchase cost, and cost of decontamination, repair, and waste disposal. Results and discussion The carbon footprint of reusable scissors was 70 g CO 2 e per use, assuming scissors were used 40 times before replacement. This was reduced by 19% through use of offsite repair every 40 uses (57 g CO 2 e/scissor use), with small additional reductions associated with onsite repair (56 g CO 2 e/scissor use). Similar patterns of reduction were calculated for eighteen midpoint environmental impact categories (mean impact reduction of 30% for those repaired offsite relative to no repair) and also across three endpoint categories. Decontamination made the biggest contribution to the carbon footprint across all baseline scenarios (76% where no repair, 95–97% where repaired offsite and onsite respectively). Findings were robust to alternative scenario analyses. Life cycle cost was GBP £1.43 per use of reusable scissors, and when repaired either on- or offsite this decreased by 32% to GBP £0.97 per use. Conclusion Repairing surgical scissors rather than replacing them with a new pair can reduce environmental and financial cost. The extent to which repair may play a role in mitigating the environmental impact of other surgical instruments requires further research.

Background: Socioeconomically deprived women have lower rates of breast cancer but higher mortality rates than their less deprived counterparts. This may reflect later stage at diagnosis and variation in rates of treatment, although part of the excess mortality may be due to the association between deprivation and poor general health. This study aimed to explore associations between socioeconomic deprivation, stage at diagnosis, treatment allocation and survival in a prospective cohort study of women over 70 years old.
