RESUMEN

BACKGROUND: Cancer multidisciplinary team (MDT) meetings are under intense pressure to reform given the rapidly rising incidence of cancer and national mandates for protocolized streaming of cases. The aim of this study was to validate a natural language processing (NLP)-based web platform to automate evidence-based MDT decisions for skin cancer with basal cell carcinoma as a use case. METHODS: A novel and validated NLP information extraction model was used to extract perioperative tumour and surgical factors from histopathology reports. A web application with a bespoke application programming interface used data from this model to provide an automated clinical decision support system, mapped to national guidelines and generating a patient letter to communicate ongoing management. Performance was assessed against retrospectively derived recommendations by two independent and blinded expert clinicians. RESULTS: There were 893 patients (1045 lesions) used to internally validate the model. High accuracy was observed when compared against human predictions, with an overall value of 0.92. Across all classifiers the virtual skin MDT was highly specific (0.96), while sensitivity was lower (0.72). CONCLUSION: This study demonstrates the feasibility of a fully automated, virtual, web-based service model to host the skin MDT with good system performance. This platform could be used to support clinical decision-making during MDTs as 'human in the loop' approach to aid protocolized streaming. Future prospective studies are needed to validate the model in tumour types where guidelines are more complex.

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) represents the most commonly occurring cancer worldwide within the white population. Reports predict 298 308 cases of BCC in the UK by 2025, at a cost of £265-366 million to the National Health Service (NHS). Despite the morbidity, societal and healthcare pressures brought about by BCC, routinely collected healthcare data and global registration remain limited. OBJECTIVES: To calculate the incidence of BCC in Wales between 2000 and 2018 and to establish the related healthcare utilization and estimated cost of care. METHODS: The Secure Anonymised Information Linkage (SAIL) databank is one of the largest and most robust health and social care data repositories in the UK. Cancer registry data were linked to routinely collected healthcare databases between 2000 and 2018. Pathological data from Swansea Bay University Health Board (SBUHB) were used for internal validation. RESULTS: A total of 61 404 histologically proven BCCs were identified within the SAIL Databank during the study period. The European age-standardized incidence for BCC in 2018 was 224.6 per 100 000 person-years. Based on validated regional data, a 45% greater incidence was noted within SBUHB pathology vs. matched regions within SAIL between 2016 and 2018. A negative association between deprivation and incidence was noted with a higher incidence in the least socially deprived and rural dwellers. Approximately 2% travelled 25-50 miles for dermatological services compared with 37% for plastic surgery. Estimated NHS costs of surgically managed lesions for 2002-2019 equated to £119.2-164.4 million. CONCLUSIONS: Robust epidemiological data that are internationally comparable and representative are scarce for nonmelanoma skin cancer. The rising global incidence coupled with struggling healthcare systems in the post-COVID-19 recovery period serve to intensify the societal and healthcare impact. This study is the first to demonstrate the incidence of BCC in Wales and is one of a small number in the UK using internally validated large cohort datasets. Furthermore, our findings demonstrate one of the highest published incidences within the UK and Europe.

RESUMEN

BACKGROUND: There is limited evidence in the literature on the long-term effectiveness and cost-effectiveness of treatments for Acute Severe Ulcerative Colitis (ASUC). The study aimed to perform decision analytic model-based long-term cost-utility analysis (CUA) of infliximab versus ciclosporin for steroid-resistant ASUC investigated in CONSTRUCT pragmatic trial. METHODS: A decision tree (DT) model was developed using two-year health effect, resource use and costs data from CONSTRUCT trial to estimate relative cost-effectiveness of two competing drugs from the United Kingdom (UK) National Health Services (NHS) perspective. Using short-term trial data, a Markov model (MM) was then developed and evaluated over further 18 years. Both DT and MM were combined to investigate cost-effectiveness of infliximab versus ciclosporin for ASUC patients over 20-year time horizon, with a rigorous multiple deterministic and probabilistic sensitivity analyses to address uncertainty in results. RESULTS: The decision tree mirrored trial-based results. Beyond 2-year trial follow-up, Markov model predicted a decrease in colectomy rate, but it remained slightly higher for ciclosporin. NHS costs and quality adjusted life years (QALYs) over base-case 20 year time horizon were £26,793 and 9.816 for ciclosporin and £34,185 and 9.106 for infliximab, suggesting ciclosporin dominates infliximab. Ciclosporin had 95% probability of being cost-effective at a willingness-to-pay (WTP) threshold value up to £20,000. CONCLUSION: Using data from a pragmatic RCT, the cost-effectiveness models produced incremental net health benefit in favour of ciclosporin relative to infliximab. Results from long-term modelling indicated that ciclosporin remains dominant compared with infliximab for the treatment of NHS ASUC patients, however, these need to be interpreted cautiously. TRIAL REGISTRATION: CONSTRUCT Trial registration number ISRCTN22663589; EudraCT number: 2008- 001968-36 (Date 27/08/2008).

RESUMEN

INTRODUCTION: The introduction of information technology was one of the key priorities for policy-makers in health care organisations over the last two decades due to the potential benefits of this technology to improve health care services and quality. However, approximately 50% of those projects failed to achieve their intended aims. This was a result of several factors, including the cost of these projects. The Saudi Ministry of Health (MoH) planned to implement an electronic health record system (EHRS) in approximately 2100 primary health care centres nationwide. It was acknowledged that this project may face hurdles, which might result in the failure of the project if implementation facilitators were not first determined. According to the Saudi MoH, previous electronic health record system implementation in primary health care centres failed as a consequence of several barriers, such as poor infrastructure, lack of connectivity and lack of interoperability. However, the facilitators of successful electronic health record system implementation in Saudi primary health care centres are not understood. AIM: To determine the facilitators that enhance the success of the implementation of an EHRS in public primary health care centres in SA. METHOD: A mixed methods approach was used with both qualitative and quantitative methods (qualitative using semistructured interviews and quantitative with a closed survey). The purpose of the utilisation of exploratory mixed methods was to identify a wide range of facilitators that may influence EHRS implementation. The data were obtained from two different perspectives, primary health care centre practitioners and project team members. A total of 351 practitioners from 21 primary health care centres participated in the online survey, and 14 key informants at the Saudi Ministry of Health who were directly involved in the electronic health record system implementation in the primary health care centres agreed to be interviewed face to face. RESULTS: The findings from both studies revealed several facilitators. Among these facilitators, financial resources were found to be the most influential factor that assisted in overcoming some barriers, such as software selection. The size of the primary health care centres was the second facilitator of successful implementation, despite the scale of the project. Perceived usefulness was another facilitator identified in both the interviews and the survey. More than 90% of the participants thought that the electronic health record system was useful and could contribute to improving the quality of health care services. While a high level of satisfaction was expressed towards the electronic health record system's usability and efficiency, low levels of satisfaction were recorded for organisational factors such as user involvement, training and support. Hence, system usability and efficiency were documented to be other facilitators of successful electronic health record system implementation in Saudi primary health care centres. CONCLUSION: The findings of the present study suggest that sufficient financial support is essential to enhance the success of electronic health record system implementation despite the scale of the project. Additionally, effective leadership and project management are core factors to overcome many obstacles and ensure the success of large-scale projects.

RESUMEN

OBJECTIVES: Listening effort may be defined as the attentional and cognitive resources needed to understand an auditory message, modulated by motivation. Despite the use of hearing devices such as hearing aids or cochlear implants (CIs), the requirement for high listening effort remains a challenge for individuals with hearing loss. The Listening Effort Questionnaire-Cochlear Implant (LEQ-CI) is a hearing-specific patient-reported outcome measure (PROM), which has been designed for use in the CI candidacy and rehabilitation process to assess perceived listening effort in everyday life in adults with severe-profound hearing loss. The LEQ-CI has been developed in line with international consensus-based standards for best practice in PROM construction. The aim of this study was to improve the measurement precision of the LEQ-CI and to assess its psychometric measurement properties. DESIGN: A field test was undertaken with 330 CI patients from five National Health Service auditory implant centers in the United Kingdom. Participants were adults (≥18 years of age), had a severe-profound hearing loss, and met the UK candidacy criteria for cochlear implantation specified by the National Institute for Health and Care Excellence (NICE). Participants completed and returned an anonymized 29-item (each with a 5- or 7-point response option), draft version of the LEQ-CI (LEQ-CI29) and a demographic questionnaire. Rasch analysis was undertaken using Winsteps software and the partial credit model to assess rating scale function and item fit. Results informed refinements to produce a 21-item version (LEQ-CI21), which underwent a further Rasch analysis. RESULTS: The sample was predominantly female: 60.3% (n = 191). Median age of participants was 66 (range 21 to 89) years, with 7.3% (n = 24) of respondents being CI candidates and 92.7% (n = 306) being CI recipients. Mean duration of implantation was 3.8 (SD = 4.8) years. Initial Rasch analysis of the LEQ-CI29 revealed poor rating scale functioning. Collapsing the 5- and 7-point rating scales to 3- and 4-point scales and removing eight items produced a 21-item PROM (LEQ-CI21). Rasch analysis of the LEQ-CI21 showed good fit to the Rasch measurement model. No items showed misfit and dimensionality analysis supported the existence of a single Rasch dimension, defined as perceived listening effort in daily life. Person reliability was 0.91 and the person separation index was 3.28, establishing four levels of person ability. The item separation index was 9.69, confirming the item hierarchy. No items showed differential item functioning for gender or age. The item difficulty range was -0.81 to 1.05, the person ability range for nonextreme persons was -3.54 to 2.49, and the mean person ability was -0.31. CONCLUSIONS: Overall, the LEQ-CI21 was found to meet the Rasch model criteria for interval-level measurement. The LEQ-CI21 is the first PROM to be developed specifically for the measurement of perceived listening effort and one of the first patient-reported outcome measures for use with CI patients to be developed using Rasch analysis. The LEQ-CI21 has the potential to be used as a research tool and in clinical practice to evaluate perceived listening effort in daily life. Further psychometric evaluation of the LEQ-CI21 is planned.

RESUMEN

ABSTRACT: In medicine, "big data" refers to the interdisciplinary analysis of high-volume, diverse clinical and lifestyle information on large patient populations. Recent advancements in data storage and electronic record keeping have enabled the expansion of research in this field. In the United Kingdom, Big data has been highlighted as one of the government's "8 Great Technologies," and the Medical Research Council has invested more than £100 million since 2012 in developing the Health Data Research UK infrastructure. The recent Royal College of Surgeons Commission of the Future of Surgery concluded that analysis of big data is one of the 4 most likely avenues to bring some of the most innovative changes to surgical practice in the 21st century.In this article, we provide an overview of the nascent field of big data analytics in plastic and highlight how it has the potential to improve outcomes, increase safety, and aid service planning.We outline the current resources available, the emerging role of big data within the subspecialties of burns, microsurgery, skin and breast cancer, and how these data can be used. We critically review the limitations and considerations raised with big data, offer suggestions regarding database optimization, and suggest future directions for research in this exciting field.

RESUMEN

BACKGROUND: In recent years, researchers and clinicians have been developing prognostic prediction tools (PPTs) as a way of identifying patients at risk of deterioration. The use of PPTs in the clinical environment not only impacts the risk of adverse outcomes for patients, but the use of these tools also effect clinical practice. Much attention has been paid to the clinical performance of PPTs. But more insight is needed on how the use of PPTs impacts clinical practice. The objective of this study was to map some of the ways in which PPTs effect clinical practice. The STUMBL (STUdy evaluating the impact of a prognostic model for Management of BLunt chest wall trauma patients) feasibility trial evaluated the use of a new prognostic prediction tool (PPT) to guide the management blunt chest wall trauma patients in the emergency departments (ED). The trial was undertaken between October 2016 and September 2018 and conducted at four sites in England and Wales. Nested within the feasibility trial was a qualitative study aimed at understanding how ED clinicians experienced and used the PPT. The qualitative methods included a focus group and telephone interviews with 9 ED clinicians. This study focused on participant perceptions of the feasibility and use of the STUMBL tool on clinical practice in the ED. RESULTS: Clinical practice is reshaped as a result of the introduction of the STUMBL PPT into the clinical environment. The PPT enhanced reflexive awareness of prognostic practice; facilitated communication between patients and professionals; helps to guide patient outcomes; and provides a common ground for clinician discussion on prognostication. CONCLUSIONS: The qualitative data collected offered useful insights into the ways in which the tool changes clinical practice. This was a small study of the effect of one kind of PPT on clinical practice. Nevertheless, this study maps areas in which clinical practice is affected by the introduction of a PPT into the clinical environment. More research is needed to better understand these effects, and to understand how these tools become embedded in clinical practice over the longer term.

RESUMEN

BACKGROUND: A nested qualitative interview study within the CONSTRUCT trial was conducted to explore experiences and perceptions of patients with acute severe ulcerative colitis following treatment with infliximab or ciclosporin, surgery, or other medication. METHODS: Two hundred seventy patients with steroid-resistant ulcerative colitis were randomised to either infliximab or ciclosporin. Interviews were conducted with 20 trial participants. Thirty-five data capture events took place in total, 20 interviews conducted 3 months after treatment and a further 15 interviews with the same cohort as second interviews at 12 months. RESULTS: Disease duration varied but similar stories emerged about how people adjusted to living with ulcerative colitis. Issues raised by patients included; the debilitating effect of the disease on quality of life, living with the unpredictability of symptoms and treatment, dealing with embarrassment and stigma and the desire to share knowledge of the disease with others to combat the private nature of this debilitating illness and bring greater visibility to patient experience of symptoms and outcomes. CONCLUSION: Patients were more positive about treatment with infliximab than ciclosporin, mainly due to the cumbersome intravenous regimen required for ciclosporin. Prompt diagnosis is required and early reporting of changes in symptoms is encouraged to ensure appropriate treatment. TRIAL REGISTRATION: This trial is registered with the ISRCTN registry; number ISRCTN22663589 . The date of registration was 16/05/2008.

RESUMEN

OBJECTIVES: Individuals with hearing loss often report a need for increased effort when listening, particularly in challenging acoustic environments. Despite audiologists' recognition of the impact of listening effort on individuals' quality of life, there are currently no standardized clinical measures of listening effort, including patient-reported outcome measures (PROMs). To generate items and content for a new PROM, this qualitative study explored the perceptions, understanding, and experiences of listening effort in adults with severe-profound sensorineural hearing loss before and after cochlear implantation. DESIGN: Three focus groups (1 to 3) were conducted. Purposive sampling was used to recruit 17 participants from a cochlear implant (CI) center in the United Kingdom. The participants included adults (n = 15, mean age = 64.1 years, range 42 to 84 years) with acquired severe-profound sensorineural hearing loss who satisfied the UK's national candidacy criteria for cochlear implantation and their normal-hearing significant others (n = 2). Participants were CI candidates who used hearing aids (HAs) and were awaiting CI surgery or CI recipients who used a unilateral CI or a CI and contralateral HA (CI + HA). Data from a pilot focus group conducted with 2 CI recipients were included in the analysis. The data, verbatim transcripts of the focus group proceedings, were analyzed qualitatively using constructivist grounded theory (GT) methodology. RESULTS: A GT of listening effort in cochlear implantation was developed from participants' accounts. The participants provided rich, nuanced descriptions of the complex and multidimensional nature of their listening effort. Interpreting and integrating these descriptions through GT methodology, listening effort was described as the mental energy required to attend to and process the auditory signal, as well as the effort required to adapt to, and compensate for, a hearing loss. Analyses also suggested that listening effort for most participants was motivated by a need to maintain a sense of social connectedness (i.e., the subjective awareness of being in touch with one's social world). Before implantation, low social connectedness in the presence of high listening effort encouraged self-alienating behaviors and resulted in social isolation with adverse effects for participant's well-being and quality of life. A CI moderated but did not remove the requirement for listening effort. Listening effort, in combination with the improved auditory signal supplied by the CI, enabled most participants to listen and communicate more effectively. These participants reported a restored sense of social connectedness and an acceptance of the continued need for listening effort. CONCLUSIONS: Social connectedness, effort-reward balance, and listening effort as a multidimensional phenomenon were the core constructs identified as important to participants' experiences and understanding of listening effort. The study's findings suggest: (1) perceived listening effort is related to social and psychological factors and (2) these factors may influence how individuals with hearing loss report on the actual cognitive processing demands of listening. These findings provide evidence in support of the Framework for Understanding Effortful Listening a heuristic that describes listening effort as a function of both motivation and demands on cognitive capacity. This GT will inform item development and establish the content validity for a new PROM for measuring listening effort.

RESUMEN

Breast cancer risk classifications are useful for prognosis, yet little is known of their effect on patients. This study clarified women's understandings of risk as they "journeyed" through the health care system. Breast cancer patients and women undergoing genetic investigation were recruited ( N = 25) from a large UK Health Board, 2014-2015, completing a "Book of Experience," and Bio-photographic elicitation interviews. Stakeholder and Participant Feedback Forums were undertaken with key stakeholders, including patients, oncologists, funders, and policy developers, to inform team understanding. Thematic and visual frameworks from multidisciplinary analysis workshops uncovered two themes: "Subjective Understandings of Risk" and "Journeying Toward an Unknown Future." Breast cancer patients and women undergoing investigation experienced risk intuitively. Statistical formulations were often perplexing, diverting attention away from concrete life-and-death facts. Following risk classification, care must be co-defined to reduce patients' foreboding about an unknown future, taking into consideration personal risk management strategies and aspirations for a cancer-free future.

RESUMEN

BACKGROUND AND STUDY AIMS: Patient satisfaction is a key indicator of the quality of gastrointestinal (GI) endoscopy. The aim of this study was to develop and validate a specific patient satisfaction questionnaire for patients undergoing GI endoscopy--the Gastrointestinal Endoscopy Satisfaction Questionnaire (GESQ). PATIENTS AND METHODS: We developed and validated the GESQ within the context of a national multi-institution nurse endoscopy trial, based in secondary care, in three stages: (1) item generation with a panel of patients and professionals following a detailed literature review to identify the most relevant items from existing scales; (2) development and piloting of a draft questionnaire on a sample of patients referred for GI endoscopy; and (3) testing of the questionnaire within a large multicenter pragmatic randomized trial. We undertook psychometric analysis of the questionnaire to identify the underlying dimensions and assessed the questionnaire for reliability and validity. RESULTS: The final version of the GESQ contains 21 items. Principal components analysis revealed four subscales with high internal consistency: skills and hospital (seven items; Cronbach's alpha 0.83), pain and discomfort during and after endoscopy (four items; Cronbach's alpha 0.84), information before endoscopy (five items; Cronbach's alpha 0.80), and information after endoscopy (five items; Cronbach's alpha 0.76). CONCLUSIONS: The four identified subscales are clinically relevant and correspond to domains of patient satisfaction identified in previous studies. Our development and validation of the GESQ confirmed that it is a valid, reliable, interpretable, and acceptable tool to measure satisfaction in patients who have undergone a GI endoscopy.

RESUMEN

This review paper makes the case for the usefulness of qualitative research methods in the context of epilepsy research. It begins with an assessment of the current state of epilepsy literature and identifies gaps especially in the following: research in 'developing' countries and research around surgery for adults with epilepsy. It makes the case that disclosure of people's behaviors, actions, and reactions in different, often complex health-care situations can indicate how they bring meaning to their disease experiences and support needs. It shows the value of encouraging work that clarifies how patients manage their illness and how they understand changes in their health and well-being over the life course of their illness and how health-care professionals and other stakeholder groups care for those with epilepsy. The paper suggests a range of methods for addressing gaps in the literature and highlights a range of data collection, data analysis, and data interpretation and synthesis techniques that are appropriate in this context. It pays particular attention to the strengths of qualitative applications in mixed-methods research using an example from a recent ulcerative colitis drug trial that indicates how they can be integrated into study findings, add rich description, and enhance study outcomes. Ethnographic methodology is also presented, as a way of offering rare access to the 'lived experience' dimension, before the paper concludes with an assessment of the qualitative criteria of credibility, dependability, transferability, and confirmability for judging a study's 'trustworthiness'. The criteria evidence not only the trustworthiness of data and findings but also the ways in which a study has approached any challenges inherent in its research design.

RESUMEN

INTRODUCTION: Data supporting the current British Association of Dermatologists guidelines for the management of basal cell carcinoma (BCC) are based on historic studies and do not consider the updated Royal College of Pathologists (RCPath) histological reporting standards. The aim of this study was to use natural language processing (NLP)-derived data and undertake a multivariate analysis with updated RCPath standards, providing a contemporary update on the excision margins required to achieve histological clearance in BCC. METHODS: A validated NLP information extraction model was used to perform a rapid multi-centre, pan-specialty, consecutive retrospective analysis of BCCs, managed with surgical excision using a pre-determined clinical margin, over a 17-year period (2004-2021) at Swansea Bay University Health Board. Logistic regression assessed the relationship between the peripheral and deep margins and histological clearance. RESULTS: We ran our NLP algorithm on 34,955 BCCs. Out of the 1447 BCCs that met the inclusion criteria, the peripheral margin clearance was not influenced by the BCC risk level (p = 0.670). A clinical peripheral margin of 6 mm achieved a 95% histological clearance rate (95% confidence interval [CI], 0.93-0.98). Tumour thickness inversely affected deep-margin histological clearance (OR 0.720, 95% CI, 0.525-0.991, p < 0.05). Depth level 2 had a 97% probability of achieving deep-margin histological clearance across all tumour thicknesses. CONCLUSION: Updated RCPath reporting standards minimally impact the peripheral margin histological clearance in BCC. Larger clinical peripheral margins than those indicated by current guidelines may be necessary to achieve excision rates of ≥95%. These findings emphasise the need for continuous reassessment of clinical standards to enhance patient care.

RESUMEN

BACKGROUND AND AIMS: In 2020 we reported the ACE Index in acute colitis which used biochemical and endoscopic parameters to predict steroid non-response on admission in patients with acute ulcerative colitis [UC]. We aimed to validate the ACE Index in an independent cohort. METHODS: The validation cohort comprised patients screened as eligible for inclusion in the CONSTRUCT study, a prospective, randomized, placebo-controlled trial which compared the effectiveness of treatment with infliximab vs ciclosporin in patients admitted with acute UC. The CONSTRUCT cohort database was reviewed at The Edinburgh IBD Unit and the same biochemical and endoscopic variables and cut-off values as those in the derivation cohort were applied to the validation cohort. RESULTS: In total, 800 patients were identified; 62.5% [55/88] of patients with a maximum ACE Index of 3 did not respond to intravenous [IV] steroids (positive predictive value [PPV] 62.5%, negative predictive value [NPV] 79.8%). Furthermore, 79.8% [158/198] of patients with an ACE Index of 0 responded to IV steroids [PPV 79.8%, NPV 62.5%]. Receiver operator characteristic [ROC] curve analysis produced an area under the curve [AUC] of 0.663 [p < 0.001]. CONCLUSIONS: We have now reported and externally validated the ACE Index in acute colitis in a combined cohort of over 1000 patients from across the UK. The ACE Index may be used in conjunction with clinical judgement to help identify patients admitted with active UC who are at high risk of not responding to IV steroids. Further studies are required to improve objectivity and accuracy of assessment.

RESUMEN

OBJECTIVE: To determine if quality of life (QoL) changes before, during and after menopause and whether these changes are linked to symptoms, demographics, and/or lifestyle factors. METHODS: We undertook a cross-sectional online survey. We invited women aged between 35 and 60 years to complete the survey which included the Short-Form 36 (SF-36) generic quality of life measure, the menopause specific Utian-Quality of life (UQOL) measure, and questions about health and wellbeing, menopause symptoms and hormonal stage. The data were analysed with one-way ANOVA analysis and multivariate regression modelling. RESULTS: 279 women completed the survey. Most were aged between 51 and 55 years. In the unadjusted analysis there was a tendency for QoL to deteriorate from pre to peri to menopause and then increase slightly post menopause. This was however not significant in multivariate analysis. Multivariate analysis identified that lifestyle factors significantly influenced QoL. Regular exercise resulted in better QoL scores across a number of the UQol and SF-36 sub-scales. Being very overweight and having more menopause symptoms resulted in worse QoL. CONCLUSIONS: Although there was a trend towards worse quality of life in the peri and menopause stages this was not significantly different in adjusted multivariate analyses. Those experiencing more symptoms had significantly worse QoL. Lifestyle factors may affect QoL, but the picture is not straightforward. It is promising that there was a trend toward improved QoL in the post-menopausal stage. These findings should inform education material and promote awareness of the menopause and its impact on QoL.

RESUMEN

INTRODUCTION: Skin cancer is the most common form of cancer in the UK, comprising at least 25% of all new cancer diagnoses. Many patients require referral to the local or specialist skin cancer multidisciplinary team (MDT) for ongoing management. However, national data have shown that Specialist Skin Cancer MDTs are costly and do not currently meet NICE standards for composition and quoracy. Innovative solutions to these problems are therefore warranted. METHODS: We performed a secondary comparative analysis of 3563 quantitative responses to two Cancer Research UK commissioned surveys along with subanalysis of 282 skin cancer MDT respondents. RESULTS: Good uniformity was observed amongst skin respondents in the belief that risk stratification and prioritization of complex cases were the most important factors compared to other cancer MDT members. The most important priorities for areas requiring change to MDT working deemed by the skin MDT were 1) imaging and pathology results ready for the meeting, 2) time to discuss patients in detail, 3) clear meeting owner in charge, and 4) clear agenda, in advance of the meeting. There was agreement (median Likert score 4) amongst skin MDT respondents that patients should be placed on protocolized treatment pathways. CONCLUSION: The responses of skin MDT respondents analyzed in the current study support changes to meeting attendance, preparation, and protocolized streaming. In line with other studies, we support tumor-specific guidance for streamlining MDT discussions. We also encourage stakeholders to adopt an evidence-based approach to test, develop, and reassess changes in this herculean task.

RESUMEN

INTRODUCTION: Prior to the COVID-19 pandemic, there was concern that virtual or remote multidisciplinary teams (MDT) meetings represented a niche concept that was unlikely to replace traditional face-to-face meetings in the management of cancer. However, the sudden shift to virtual meetings during COVID-19 has been one of the most dramatic changes since the inception of the MDT. This study aims to investigate the effectiveness of virtual skin MDTs since the move to virtual meetings. METHODS: A cross-sectional survey was sent to all Specialist Skin Cancer MDTs (SSMDTs) and the British Association of Plastic, Reconstructive, and Aesthetic Surgeons Skin Oncology Special Interest and Advisory Group. RESULTS: There were 68 responses (55.3% response rate) from 36 SSMDTs in the UK. Respondents felt communication, chairing, and decision-making were similar in virtual and in-person MDTs, but the team working was worse in virtual meetings. Recruitment, data security, and patient confidentiality were maintained in virtual MDTs. Most preferred a hybrid format for future MDTs, with the option to attend virtually. Recommendations for improvement included better connectivity, IT support, training, and staff integration. CONCLUSION: The virtual MDT is here to stay. We highlight the strengths and weaknesses of remote virtual skin MDTs. It is key that we look at ways to retain team working to ensure that the collegiate nature of MDT working, and therefore treatment options for patients, are not lost in this transformation in MDT delivery.

RESUMEN

INTRODUCTION: Amid clinicians' challenges in staying updated with medical research, artificial intelligence (AI) tools like the large language model (LLM) ChatGPT could automate appraisal of research quality, saving time and reducing bias. This study compares the proficiency of ChatGPT3 against human evaluation in scoring abstracts to determine its potential as a tool for evidence synthesis. METHODS: We compared ChatGPT's scoring of implant dentistry abstracts with human evaluators using the Consolidated Standards of Reporting Trials for Abstracts reporting standards checklist, yielding an overall compliance score (OCS). Bland-Altman analysis assessed agreement between human and AI-generated OCS percentages. Additional error analysis included mean difference of OCS subscores, Welch's t-test and Pearson's correlation coefficient. RESULTS: Bland-Altman analysis showed a mean difference of 4.92% (95% CI 0.62%, 0.37%) in OCS between human evaluation and ChatGPT. Error analysis displayed small mean differences in most domains, with the highest in 'conclusion' (0.764 (95% CI 0.186, 0.280)) and the lowest in 'blinding' (0.034 (95% CI 0.818, 0.895)). The strongest correlations between were in 'harms' (r=0.32, p<0.001) and 'trial registration' (r=0.34, p=0.002), whereas the weakest were in 'intervention' (r=0.02, p<0.001) and 'objective' (r=0.06, p<0.001). CONCLUSION: LLMs like ChatGPT can help automate appraisal of medical literature, aiding in the identification of accurately reported research. Possible applications of ChatGPT include integration within medical databases for abstract evaluation. Current limitations include the token limit, restricting its usage to abstracts. As AI technology advances, future versions like GPT4 could offer more reliable, comprehensive evaluations, enhancing the identification of high-quality research and potentially improving patient outcomes.

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) remain the most prevalent malignancies, contributing a higher workload to cancer registries than all cancers combined. The nature of skin cancers in addition to current coding methods employed by registries give a skewed representation of the workload. OBJECTIVES: A comprehensive search examining the incidence of BCC and/or cSCC at a regional or national level in the UK and Ireland was devised. Standardisation methods were grouped to permit comparison, and a bias assessment tool was employed. MATERIALS & METHODS: Sixteen UK and Republic of Ireland epidemiological studies on BCC/cSCC over a 48-year period were compiled, examining incidence, trends and emerging risk factors. RESULTS: Incidence of BCC within the UK is increasing annually by up to 4%, with rates in Wales increasing by up to 6.6% and 1.6% annually for BCC and cSCC, respectively. Inverse relationships are noted between BCC/cSCC and social deprivation. Although the elderly remain the most at risk, the 30-49 age group have illustrated growth rates of approximately 4%. CONCLUSION: This review outlines increasing incidence in the UK with higher rates noted in Wales, the Southeast, West and Central regions. Incidence rates are higher amongst the least socially deprived and an increasing incidence amongst younger age groups was found, however further trend analysis is required. A more comprehensive data collection method within registries is necessary to ensure accurate representation and fluid comparison. Service planning and public awareness campaigns must be implemented to prevent overwhelming future services.
