The use of generative artificial intelligence in surgical education: a narrative review

The introduction of generative artificial intelligence (AI) has revolutionized healthcare and education. These AI systems, trained on vast datasets using advanced machine learning (ML) techniques and large language models (LLMs), can generate text, images, and videos, offering new avenues for enhancing surgical education. Their ability to produce interactive learning resources, procedural guidance, and feedback post-virtual simulations makes them valuable in educating surgical trainees. However, technical challenges such as data quality issues, inaccuracies, and uncertainties around model interpretability remain barriers to widespread adoption. This review explores the integration of generative AI into surgical training, assessing its potential to enhance learning and teaching methodologies. While generative AI has demonstrated promise for improving surgical education, its integration must be approached cautiously, ensuring AI input is balanced with traditional supervision and mentorship from experienced surgeons. Given that generative AI models are not yet suitable as standalone tools, a blended learning approach that integrates AI capabilities with conventional educational strategies should be adopted. The review also addresses limitations and challenges, emphasizing the need for more robust research on different AI models and their applications across various surgical subspecialties. The lack of standardized frameworks and tools to assess the quality of AI outputs in surgical education necessitates rigorous oversight to ensure accuracy and reliability in training settings. By evaluating the current state of generative AI in surgical education, this narrative review highlights the potential for future innovation and research, encouraging ongoing exploration of AI in enhancing surgical education and training.

Environmental Impact and Sustainability Associated with the Practice of Dermatology

Purpose: The environmental impact of the practice of medicine including dermatology can be significant, driven by a growing and aging population that increasingly demands medical resources. This review explores the environmental effects of the practice of dermatology and identifies actionable solutions to reduce negative environmental impacts. Methods: A PubMed search was conducted using the terms (“environmental impact” OR “sustainability”) AND “dermatology.” Results were screened to include English-only articles between 2018 - 2024 and excluded duplicates. Further exploration of dermatology’s environmental effects was enhanced through citation tracking and additional PubMed searches. Results: A total of 25 articles were included based on relevance and search terms and an additional 21 were added. Results were categorized into six categories for data representation. Patient travel was the largest contributor to negatively impact the environment, followed by waste management practices, journal publication and written patient material, and traveling to medical conferences. The environmental impact of pharmaceuticals, including topicals, is also notable. Potential sustainable alternatives include teledermatology, more appropriate waste production and segregation, and electronic versus printed formats and more virtual conferences. Additionally, dermatologic disease evolves in response to a changing environment, with new data indicating epidemiological shifts due to climate change. More sustainable practices within dermatology also have the potential to cut total overhead expenses. Conclusions: Clinical and surgical subspecialties, specifically dermatology, can contribute significantly to environmental pollution, leading to environmental and financial impacts, but implementing simple, documented methods can reduce their ecological footprint and provide potential financial benefits.

Utilization Fraction of Ambulatory Hand Procedures: Cost-Reduction Through Surgical Instrument Tray Optimization.

Our objective is to evaluate the utilization fraction (UF) of surgical instruments during a commonly performed ambulatory hand surgery case as an avenue for cost reduction, increased operating room efficiency, and systems quality improvement. The total number of instruments opened at the start of the case was recorded followed by instruments being divided into those used and not used during the procedure. Total sterile processing costs were estimated at $1.56 per instrument according to data from our institution's central sterilization processing (CSP) department. Nineteen hand procedures performed by 2 surgeons were included in this study. An average of 120.1 ± 10.9 instruments were opened at the start of each case, while an average of 12.6 ± 5.4 instruments were used per case (Figure 1). This yielded an UF of 10.7% ± 4.8%. Using our internal CSP estimate, we calculated an annual cost of $16 863 to reprocess the current hand tray (Figure 2). Using literature data, this cost ranged from $5 513 to $34 484 annually. The same cost calculations were performed for the theoretical optimized tray (incorporating instruments used at least 20% of the time when opened) containing 23.2 instruments. The annual reprocessing cost of this new tray according to CSP data was $3 260, demonstrating a cost-reduction of $13 603 or 80.7% (Figure 2). Evaluation of pre- and peri-operative processes is a valuable technique to mitigate increasing healthcare costs and reduce unnecessary healthcare spending, with broad applicability to multiple surgical subspecialties and procedures.

Botulinum Toxin Application for Treatment of Graft Vasospasm: A Reverse Translational Study.

Vascular graft vasospasm is a lethal risk when using grafts for revascularization and reconstructive surgery. Revascularization is a treatment modality for ischemic diseases including Moyamoya disease that requires bypass surgery. Cerebrovascular graft transplantation carries a 5-10% risk of vasospasm, which can lead to devastating neurological sequelae. Here we report clinical outcomes associated with ex vivo botulinum toxin A (BoNT/A) treatment of arterial graft and provide reverse translational studies investigating the potential mechanisms of action of BoNT/A to reduce vasospasm. A retrospective review of the maintained database of patients undergoing surgery was performed for 63 patients. We used paired human vascular graft tissue for ex vivo BoNT/A studies to assess for spasmolytic downstream effectors; cleaved SNAP25, pMLC, pMYPT, ROCK1/2, and levels of catecholamines. We found that low-dose BoNT/A graft treatment is associated with 1) a reduction in clinical vasospasm (13.3%, p<0.05) without any identified safety concerns in patients, 2) an increase in arterial cleaved SNAP25, 3) reduced levels of pMLC and pMYPT, and 4) reduced levels of catecholamines. The mechanism of action leading to vascular relaxation is likely through pleiotropic vasodilatory pathways. The application of BoNT/A as a spasmolytic has potentially safe and broad applications across multiple surgical and scientific subspecialties.

Abstract 4134863: Major Cardiovascular Events Following Non-Cardiovascular Surgeries in Minority Patients Compared to White Patients

Introduction: Racial disparities are pervasive in cardiovascular outcomes. Although disparities following cardiovascular surgery have been extensively studied, fewer current, nationwide reports exist for postoperative outcomes in non-cardiovascular surgery. Research Aim: To investigate the incidence of 30-day post-operative major adverse cardiac, cerebral and thrombotic events (MACCTE) following non-cardiovascular surgeries in non-White patients as compared to White patients. Methods: This retrospective cohort study used the 2018-2022 National Surgical Quality Improvement Program database. Patients aged 18 or older who underwent non-cardiovascular surgeries (general, gynecology, neurosurgery, orthopedics, otolaryngology, plastics, thoracic, urology, obstetrics, and interventional radiology) were included. Race/ethnicity was categorized as non-Hispanic White (Whites), Hispanic, non-Hispanic Asian (Asians), non-Hispanic Black or African American (Blacks), and non-Hispanic Others. MACCTE was defined as a composite of death, MI, cardiac arrest, stroke, PE, or DVT. Five multivariable logistic regression models were used to hierarchically adjust for age, gender, ASA class, surgical subspecialty, operation time, transfer status, and all other comorbidities. Results: Among the 3,775,920 patients: 70.9% were Whites, 11.8% Hispanics, 4.1% Asians, 11.6% Blacks, 1.5% of Other race, 58.9% female, and 46.7% had an ASA classification of 3 or greater. The MACCTE incidence was 1.95% overall and 2.01% in Whites, 1.27% Hispanics, 1.48% Asians, 2.11% Blacks, and 1.69% Others. Compared to Whites, Blacks had higher incidences of cardiac arrest (0.40% vs. 0.23%), stroke (0.17% vs. 0.15%), PE (0.47% vs. 0.34%), and DVT (0.55% vs. 0.48%), and Asians (0.18% vs 0.15%) and Others (0.21% vs. 0.15%) had a higher incidence of stroke (p&lt;0.001). With Whites as reference, the crude odds ratios, OR (95% CI) were 0.63 (0.61-0.65) in Hispanics, 0.73 (0.70-0.76) Asians, 1.05 (1.03-1.07) Blacks, and 0.84 (0.78-0.89) Others. The fully adjusted model odds ratios, OR (95% CI) were 0.88 (0.82-0.95) Hispanics, 0.89 (0.80-1.00) Asians, 1.11 (1.04-1.18) Blacks, and 0.80 (0.69-0.94) Others. Conclusion: Black patients experienced a higher MACCTE risk compared to Whites, even after adjustment for age, sex, ASA class, type of surgical procedure, and other comorbidities. These findings emphasize the importance of implementing comprehensive measures to prevent excess risk and promote equitable surgical care.

Intraoperative Acoustic Monitoring Using Threshold and Suprathreshold Pure Tone Audiometry during Cochlear Implantation Under Local Anesthesia: A Simple and Novel Method to Potentially Enhance Hearing Preservation Cochlear Implant Surgery.

To report the feasibility and potential utility of monitoring acoustic hearing on awake patients using intraoperative behavioral responses to threshold and suprathreshold stimuli while undergoing cochlear implantation (CI) under local anesthesia, without any form of sedation. Retrospective review of the first five cases performed by one surgeon. Tertiary care academic medical center. Adult patients with residual acoustic hearing undergoing CI. CI under local anesthesia, without any form of sedation. Procedural tolerance, reliability of intraoperative pure tone threshold and suprathreshold audiometry, and correlation of intraoperative findings with early postoperative residual hearing. Five ears in four patients underwent CI, including three males and one female, with a median age of 61 years. Intraoperatively, patients reported reliable behavioral responses to pure tone threshold and suprathreshold stimuli and provided real-time feedback on perceived stimulus change to the surgeon just prior to, during, and immediately following electrode insertion. All patients were able to complete the operation under local anesthesia. During electrode insertion, three cases reported no change and two cases reported diminished stimulus perception that reversed with limited electrode pull back near terminal insertion. Immediate postoperative audiograms demonstrated preservation of bone conduction thresholds within 10 dB of their preoperative baseline for all cases, suggesting hearing preservation. Three-month postoperative AzBio in quiet scores were available for two patients, measuring 45% and 94%, respectively. This report describes the feasibility of intraoperative behavioral audiometry during CI under local anesthesia, using patient feedback during electrode insertion to optimize hearing preservation surgery. Akin to other surgical subspecialties that use real-time patient feedback where objective intraoperative measures of neurofunction are imperfect, we demonstrate feasibility and potential utility of live acoustic monitoring during CI.

Welcome to the operating theatre! Introductory bootcamp in operating theatre specialities for medical students.

Since the early 2000's, the appeal of certain operating room specialties has decreasedamong medical school graduate students. The recent reform of the second and third cycles of medical studies in France provides an opportunity to set up teaching programs around operating room specialties. We have organised a teaching unit which is part of the final year of medical studies. The main objectives are: (1) to examine whether a boot camp can modify students' opinions and preconceived assumptions about a surgical and/or anaesthetist career (2) to determine whether these changes in perception, have an impact on students' interest in pursuing a surgical/anaesthetic career compared with the current situation. The "working in the operating theatre" boot camp (UETB) took place after the written exams of the sixth year of medical school, before students choose their future specialty for residency. This program included practical workshops, readings and time for exchanges surgeons and anaesthetists. At the beginning and at the end of the UETB, feedback forms were collected. The cohort included 59 students from the Toulouse medical school, academic year 2023-2024. After attending the UETB, there was a significant qualitative improvement in interest in a surgical and intensive care-anaesthesia career. Feedback on how the UETB influenced the choice of a future specialty was very positive, with statistically significant qualitive improvement., Additionally, the students' perception of a work-life quality as a surgeon and/or anaesthetist improved significantly. The outcome of this study makes a strong case for integrating additional exposure to the various surgical subspecialties into the graduate medical curriculum in France. By helping to dispel misperceptions of "a surgical/anaesthetist career" early on, opportunities such as the UETB program may enable addressing the attrition rate observed among surgical and anaesthetic residency applications.

Perceptions of homelessness: Is there variation across medical careers and specialties?

Medical students, residents and faculty are all capable of holding biases towards stigmatised groups like people experiencing homelessness. This study sought to investigate how the level of training may influence perceptions of homelessness among medical students, residents and faculty. Additionally, we sought to understand how different specialities perceive people experiencing homelessness and whether this changes at various points in a career. The Health Professionals' Attitudes Towards the Homeless Inventory (HPATHI) was administered to medical students, residents and faculty at one institution in the United States. Basic demographics as well as length of time spent in practice were collected in addition to HPATHI responses. A total of 1,141 individuals were invited to complete the survey, including 736 medical students, 214 residents and 191 faculty. Two hundred and ninety individuals participated in the survey and 238 recorded complete responses were analysed for a sample response rate of 238/1141 (20.9%.) Overall perceptions of homelessness across the entire sample were positive and not greatly influenced by the level of training during a medical career. Medical students across classes were largely in agreement and there was a noticeable increase in positive perceptions for students engaged in clinical rotations. However, clinical specialties demonstrated wide variation in perceptions, with the most prominent differences amongst individuals from surgical subspecialties of General Surgery and Obstetrics & Gynaecology. Our study demonstrates the largely favourable attitudes physicians, residents and students have towards people experiencing homelessness with implications for future work to support greater exposure to underserved populations during training. Specialty choice appears to play a larger role in the formation of attitudes towards underserved populations rather than the length of time spent in a particular specialty.

Holding the Knife on Perceptions of Surgery

Negative stereotypes associated with surgery by medical students are well documented in literature. Many cite long hours, poor work-life balance, pessimism, mean personalities, and cynicism as pervasive among surgeons and operating room culture. If allowed to persist, these negative perceptions can deter otherwise interested students from pursuing surgical subspecialties. Incorporation of peer-teaching in the third-year clerkship to not only illuminate the hidden curriculum in surgery but adequately prepare students to participate in the operating room is paramount to taking steps to improve student perception as well as success as clerkship students. An academic medical center. Pre-clinical medical students. One-hundred and forty-three third year clerkship students were surveyed with pre- and postinstruments. Students who participated in these pre clerkship peer-teaching sessions reported significant improvements in their ability to identify surgical anatomy (p < 0.001), an increased confidence in answering questions from attendings about anatomy and function as well as in identifying anatomical abnormalities (all p < 0.001). Students also reported significantly improved perceptions about surgeons as teachers and their willingness to support students pursuing surgery. This study demonstrates that the incorporation of an immersive orientation prior to the start of the surgery clerkship has significantly positive impacts on the learning experience and confidence of medical students. Increased efforts should be made to introduce students to surgeons, surgical careers, and the operating room prior to the surgery clerkship, being sure to incorporate aspects of the hidden curriculum, to address the negative perceptions that continue to exist regarding surgical fields.

The state of global surgery assessment and data collection tools: A scoping review.

There has been a proliferation of global surgery assessment tools designed for use in low- and middle-income countries. This scoping review sought to categorize and organize the breadth of global surgery assessment tools in the literature. The search was conducted using PubMed from October 2022 to April 2023 according to PRISMA extension for scoping review guidelines. The search terms were (("global surgery"[All Fields]) AND ("assessment"[All Fields]) OR (data collection)). Only tools published in English that detailed surgical assessment tools designed for low- and middle-income countries were included. The search resulted in 963 papers and 46 texts described unique tools that were included for the final review. Of these, 30 (65%) tools were quantitative, 1 (2%) qualitative, and 15 (33%) employed mixed-methods. 25 (54%) tools evaluated surgery in general, whereas 21 (46%) were focused on various surgical subspecialties. Qualitatively, major themes among the tools were noted. There was significant overlap of many tools. Nonspecialty surgery was represented more than any specialty surgery and many specialties had little or no representation in the literature. Ideally, local leadership should be involved in surgical assessment tools. Different methodologies, such as checklists and observational studies, aimed to target varying aspects of surgery and had distinct strengths and weaknesses. Further efforts should focus on expanding tools in neglected specialties.

A breath of fresh air: a pilot flipped classroom approach to airway management skills training

ObjectivesWhile flipped classroom instruction has repeatedly shown efficacy in undergraduate medical education, evidence for its utility in procedural domains remains sparse. This holds particular significance for surgical subspecialties such as otolaryngology, which have limited time in undergraduate medical curricula. We designed a novel airway management skills simulation course with a flipped classroom approach and evaluated its efficacy in a pilot study.MethodsA simulation course was designed to provide instruction in seven airway management skills: bag valve mask ventilation, laryngoscopy, intubation, cricothyroidotomy, tracheotomy, and tracheostomy care. Publicly available YouTube videos were selected as pre-learning materials. Participating students completed surveys before the pre-learning assignment and after completion of the simulation center workshop.ResultsSixteen students participated in the workshop, and data was collected from 14 participants. Learners reported significant improvements in knowledge regarding all covered skills except tracheotomy; mean self-rated knowledge improved from 2.9 to 5.8 (p < 0.001) on a scale from 0 to 10. Significant increases in self-reported confidence in performing all seven skills were also observed, with an overall increase from 1.1 to 5.7 (p < 0.001). Students also rated all elements of the workshop highly, including a prevailing belief that the pre-learning materials markedly enhanced their learning.ConclusionOur novel framework for skills-based education using a flipped classroom approach demonstrated remarkable efficacy in improving learner knowledge and self-reported confidence regarding airway management skills. This educational design, including the use of high-quality, publicly available pre-learning videos, has significant implications for undergraduate medical education in surgical subspecialties.

Reproductive Experiences of Physicians in Medical and Surgical Subspecialties.

Objective: To evaluate the reproductive experiences of physicians across gender and specialty. Patients and Methods: Between November and December 2021, we surveyed nontrainee physicians of all genders at a single quaternary institution using a modified version of an existing survey instrument. Experiences with family planning, fertility, pregnancy, and parental leave were assessed. Results: There were 422 completed responses. Respondents reported a higher prevalence of infertility as compared to the general U.S. population (26% versus 19%), with no difference in infertility or obstetrical complications by specialty. Most respondents (75%) reported stigma regarding having children in medicine, and 71% reported delaying childbearing. These trends were strongest in the subanalysis of female respondents. Forty-five percent of respondents reported that their work increased the risk for subfertility, infertility, or pregnancy complications. Surgeons were significantly more likely to report physically demanding work conditions (75% versus 30%, p < 0.001), radiation exposure (39% versus 14%, p < 0.001), and bloodborne pathogen exposure (25% versus 12%, p = 0.03) as occupational reproductive hazards. Only 55% of respondents with a pregnancy history reported ever taking parental leave. Among those who took less than the full amount offered, 63% cited concerns about falling behind educationally or professionally as significantly influencing this decision. Conclusions: These results support previous trends showing delayed childbearing and increased infertility among physicians while shedding new light on stigma associated with childbearing and parental leave. A better understanding of the reproductive experiences of physicians is critical to recruiting and retaining a skilled workforce and fostering career and life satisfaction in this profession.

Understanding Patient Satisfaction: A Comparative Analysis of Telemedicine versus In-person Encounters in Pediatric Plastic Surgery.

Telemedicine services experienced unprecedented growth during the coronavirus 2019 pandemic, offering patients remote access to care while minimizing exposures to possible infection. Our institution has one of the country's largest pediatric plastic surgery divisions and serves both a prominent metro area and sprawling rural community. Given the increasing utilization of telemedicine across several surgical subspecialties, this study aims to evaluate patient satisfaction following pediatric plastic surgery telemedicine encounters. Press Ganey surveys were completed by parents or guardians of pediatric plastic surgery patients after in-person or telemedicine encounters with a single surgeon. Surveys were gathered from March 2020 to December 2022. Only 13 of the 25 survey questions were applicable to both in-person and telemedicine encounters and were included for analysis. Top box scores (the proportion of patients who selected the highest rating) were compared using Fisher exact test. Completed surveys were available for both groups from June 2020 to November 2022. A total of 223 surveys met inclusion criteria; there were 159 in-person encounters and 64 telemedicine encounters. Telemedicine encounters consistently had top box scores comparable to, or greater than, in-person encounters for all 13 survey questions. Statistically significant differences were observed for ease of contacting the practice (P = 0.002) and scheduling appointments (P < 0.0001). Pediatric plastic surgery encounters completed via telemedicine demonstrate high patient satisfaction, exceeding in-person encounters for accessibility and convenience. Our study provides objective data about the patient experience and emphasizes the value of integrating telemedicine into pediatric plastic surgery practices.

Variable practice patterns in the surgical management of renal hyperparathyroidism

BackgroundHyperparathyroidism is common among patients with chronic kidney disease, end-stage kidney disease, and kidney transplant. The American Association for Endocrine Surgery published clinical practice guidelines that address the surgical treatment of secondary and tertiary hyperparathyroidism. The purpose of this study is to determine practice patterns for the surgical management of secondary and tertiary hyperparathyroidism prior to guideline publication. MethodsWith the approval of the American Association for Endocrine Surgery, a Qualtrics email survey was sent to the Association’s membership in 2022 about current clinical decision making for surgical treatment of secondary and tertiary hyperparathyroidism. Respondents were divided into groups based on surgical subspecialty (endocrine surgery versus non-endocrine surgery), yearly parathyroidectomy volume, and yearly parathyroidectomy volume for surgical treatment of secondary and tertiary hyperparathyroidism. Descriptive statistics were performed; the role of volume was evaluated. ResultsThere were 142 responses from 795 solicited email addresses (18% response rate); 114 (84%) identified as endocrine surgeons. The majority (62%) perform >50 parathyroidectomies yearly, but most perform <10 parathyroidectomies for surgical treatment of secondary and tertiary hyperparathyroidism per year (<10/y, 53.7%; 10–30/y, 41.9%; >30/y, 4.4%). Subtotal parathyroidectomy is most commonly performed for surgical treatment of secondary (83%) and tertiary (52%) hyperparathyroidism, but transcervical thymectomy variably performed for both. There was no consensus regarding starting calcitriol preoperatively (always 43%, never 25%, depends on vitamin D levels 24%) or stopping cinacalcet (2 weeks prior 28%, day of surgery 29%, postoperatively 20%). Surgeons who perform >10 parathyroidectomies per year for surgical treatment of secondary and tertiary hyperparathyroidism were less likely to consider the patient's preoperative vitamin D levels to inform their decision to start calcitriol before surgery (<10 cases/year, 34%; ≥10 cases/year 15%; P = .023), were more likely to have a postoperative hypocalcemia protocol managed by the surgical team (<10 cases/year, 49%; ≥10 cases/year, 58%; P = .029), and were more likely to use intraoperative parathyroid hormone monitoring for tertiary hyperparathyroidism (<10 cases/year, 70%; ≥10 cases/year, 87%; P = .046). ConclusionThe majority of respondents perform <10 parathyroidectomies yearly for surgical treatment of secondary and tertiary hyperparathyroidism. Subtotal parathyroidectomy was most commonly performed, but there was little other consensus regarding preoperative management, intraoperative decision-making, and postoperative care. Opportunity exists through guideline dissemination to improve heterogeneity of care provided to surgical treatment of secondary and tertiary hyperparathyroidism patients.

Preoperative and Postoperative Therapeutic Anticoagulation in Orthopaedic Surgery Increases the Risk of Bleeding: A Systematic Review and Meta-Analysis.

Patients requiring postoperative therapeutic anticoagulation may have increased risk of bleeding complications, infection, and poor wound healing. The purpose of this study was to perform a systematic review and meta-analysis assessing bleeding complication rates among orthopaedic surgery patients receiving perioperative therapeutic anticoagulation. A systematic review and meta-analysis was performed in concordance with the Preferred Reporting Items for Systematic Review and Meta Analysis 2020 guidelines. PubMed was queried for articles related to therapeutic anticoagulation in orthopaedic surgery and complications using keywords and medical subject headings. Inclusion/exclusion criteria were any study reporting bleeding complications after orthopaedic surgery among patients on perioperative therapeutic anticoagulation with a minimum 1-year follow-up. Studies were reviewed for heterogeneity and risk of bias. Pooled analysis was done to determine postoperative complication rates among patients on therapeutic anticoagulation. Thirty-seven studies with 3,990 patients were included. Studies were grouped by their surgical subspecialty with 16 from arthroplasty, one foot and ankle, two spine, one sports, 13 trauma, and four upper extremity. Among patients on therapeutic anticoagulation, the pooled rate and 95% confidence intervals of bleeding complications was 8% (5 to 11%) overall, 10% (5 to 15%) in arthroplasty, 6% (3 to 11%) in trauma, and 5% (1 to 30%) in upper extremity. The overall rates (95% CI) of venous thromboembolism (VTE) were 2% (2 to 4%), infection 5% (3 to 10%), and revision surgery 4% (3 to 6%). Upper extremity VTE rates were 0% (0 to 15%), infection 4% (3 to 6%), and revision surgery 4% (3 to 6%). Trauma VTE rates were 4% (2 to 5%), infection 2% (1 to 6%), and revision surgery 3% (2 to 4%). Arthroplasty VTE rates were 2% (1 to 5%), infection 9% (4 to 18%), and revision surgery 4% (2 to 7%). Therapeutic postoperative anticoagulation may increase the risk of bleeding complications when compared with the general population. Incidence of VTE was similar when compared with historical data.

SP1.5 - PRESS survey: PREvention of surgical site infection—a global pan-specialty survey of practice

Abstract Aims This survey aimed to establish current global practice across surgical subspecialties in the prevention of surgical site infection (SSI). Methodology A cross-sectional survey was formulated following a published protocol, aligning with established global guidelines for SSI prevention. A panel of experts provided guidance during iterative rounds of internal validation, incorporating consensus-based modifications. Prior to online dissemination via QualtricsXM link and QR code through international surgical societies, the survey underwent final external validation. Recruitment strategies were through international societies, snowballing and social media. Findings There were 1232 responses from 97 countries, with 698(56.7%) participants completing all inquiries. Responses were primarily provided by consultants or equivalent (766,75.2%), spanning all ten Royal College of Surgeons-recognised subspecialties. A significant majority (786/889,88.4%) routinely employs clinical examination for SSI diagnosis, while one-third (305/889,34.3%) never use the CDC criteria. Regarding surgical field preparation, less than half regularly use alcoholic povidone-iodine (339/778,43.6%) or chlorhexidine gluconate (370/778,47.6%). However, approximately one-third often or always use aqueous (478/1556,30.7%) or alcoholic (454/1556,29.2%) solutions for hand scrub. Surgeons exhibit a higher likelihood of changing gloves (614/734,83.7%) than instruments (513/734,69.9%) to facilitate clean skin closure. Most UK surgeons (181/206,87.9%) express equipoise in randomising patients for interventions in a potential platform trial evaluating SSI prevention. Conclusions Significant diversity characterizes global and subspecialty-specific practices in various SSI prevention measures, attributable to conflicting guidance and limited evidentiary support for recommendations. Encouragingly, a substantial number of surgeons express readiness to contribute to a robust evidence base through participation in potential platform trials for SSI prevention.

SP1.4 - PRESS survey: PREvention of surgical site infection—a global pan-specialty survey of prophylactic practices

Abstract Aims This survey aimed to establish current global practice across surgical subspecialties in the prevention of surgical site infection (SSI) using prophylactic measures. Methodology A cross-sectional survey was formulated following a published protocol, aligning with established guidelines for SSI prevention. A panel of experts provided guidance during iterative rounds of internal validation, incorporating consensus-based modifications. Prior to online dissemination via QualtricsXM link and QR code through international surgical societies, the survey underwent external validation. Recruitment strategies were through international societies, snowballing and social media. Results There were 1232 responses from 97 countries, with 698(56.7%) participants completing all inquiries. Responses were primarily provided by consultants or equivalent (766,75.2%), spanning all ten Royal College of Surgeons-recognised subspecialties. Almost all surgeons (734/779,94.2%) give pre-operative antibiotic prophylaxis at or within one hour of incision. Nutritional assessments do not routinely occur, with less than half (314/734,42.8%) performed often or always. Intraoperatively, normothermia is often or always maintained with standard blankets (389/734,53.0%) and forced air warming (435/734,59.3%) and less frequently with warmed fluids (277/734,37.7%) and heated mattresses (176/734,24.0%). Most surgeons (615/734,83.8%) would use non-iodinated drapes, whereas iodinated are used less frequently (472/734,64.3%). Triclosan coated sutures are never used by almost half of all surgeons (365/734,49.7%). Most surgeons (528/734,71.9%) use a simple wound dressing after skin closure. Conclusions Most prophylactic measures for SSI prevention display considerable variation in practice. Surgeons agree upon pre-operative antibiotic timing, in line with strong evidence and guidance. Other measures, such as antimicrobial sutures which have strong NICE recommendations, are used invariably.

WP6.15 - A dedicated teaching programme in Colorectal Surgery: continuing education beyond medical school

Abstract Background The UK Foundation Programme (UKFP) Curriculum illustrates the need for educational progression for doctors in their first two years of work. Although UKFP recommends use of departmental teaching for this, there is limited guidance on structured and learning-objective focussed training. We designed a colorectal surgery lecture series to create a reproducible teaching programme with defined learning outcomes. Methods We developed a 6-part lecture series aimed at FY1 doctors working in General Surgery at our Teaching Hospital. Teaching was in the form of 30-minute powerpoint presentations, with 15 minutes for questions, at weekly departmental teaching meetings. Lectures were delivered by FY2 doctors and members of colorectal multidisciplinary team (Enhanced Recovery CNS, Stoma Care CNS). Each session was supervised by a Colorectal Consultant. Feedback was obtained using a 10-point Likert scale questionnaire, assessing various domains. Results FY1 trainees indicated an increase in their knowledge with each lecture. Furthermore, the domains of relevance (mean score 9.53±0.80); teaching style (mean score 9.66±0.94); and audiovisual aid (mean score 9.68±0.70) were all rated highly. Lecture duration was rated as perfect length (mean score 5.86±1.80). Conclusion We have demonstrated that weekly departmental teaching can be utilised to enhance training for FY1 doctors within a challenging surgical subspecialty. Feedback revealed high satisfaction, facilitating improvement in knowledge and thus empowerment in undertaking clinical duties. Strengthened by this positive outcome work is in progress to introduce this format of structured teaching into departmental teaching meetings in all disciplines of medicine and surgery across our Trust.

Operational outcomes of community-to-academic emergency department patient transfers

BackgroundMany patients require inter-hospital transfer (IHT) to tertiary Emergency Departments (EDs) to access specialty services. The purpose of this study is to determine operational outcomes for patients undergoing IHT to a tertiary academic ED, with an emphasis on timing and specialty consult utilization. MethodsThis study was a retrospective observational cohort study at a tertiary academic hospital from 10/1/22–9/30/23. Key operational metrics, including specialty consultations, were queried from the ED Information System (EDIS). Data were analyzed for temporal variation in operational metrics and consulting patterns between transferred and non-transferred patients, stratified by time of day and week. ResultsDuring the study period there were 50,589 ED patient encounters, of which 3196 (6.3 %) were identified as IHTs. Transferred patients made up a larger proportion of patient arrivals in off-hours compared to daytime hours (p < 0.001). Transferred patients were more likely to be admitted to the hospital (76 % vs 35 %, p < 0.001), go directly to a procedure (6 % vs 2 %, p < 0.001), or receive a specialty consult (90 % vs 42 %, p < 0.001), regardless of the day of week or time of day. Relative risk of consults amongst transferred patients varied by service, though was particularly increased amongst surgical sub-specialties. ConclusionsTransferred patients represented a larger proportion of ED volume during evening and overnight hours, received more consults, and had higher likelihood of admission. Consults for transfers were disproportionately surgical subspecialties, though few patients went directly to a procedure. These findings may have operational implications in optimizing availability of specialty services across regionalized health systems.

Surgical subspecialist distribution and Social Vulnerability Indices in the inland empire

BackgroundAccess to surgical specialty care differs based on geographic location, insurance status, and subspecialty type. This study uses the Inland Empire as a model to determine the relationship between Social Vulnerability Indices (SVIs), surgeon sex, and surgical subspecialty distribution. Methods823 census tracts from the Centers for Disease Control's (CDC) SVI 2018 database were compared against 992 surgeons within 30 distinct subspecialties. This data was retrieved from the American Medical Association's (AMA) 2018 Physician Masterfile. Spearman's bivariate and multiple regression were used to compare the relationship between SVI and number of surgical subspecialists within each census tract. ResultsThere were approximately 3.34 male and 0.35 female surgeons per census tract (t(267) = 7.74, p < 0.001). Significant inverse relationships existed between Cosmetic surgery, Urology and Minority status/language (ρ = −0.131 [95 % CI −1.000 to −0.028], p = 0.016; ρ = −0.142 [95 % CI −1.000 to −0.039], p = 0.010, respectively); General surgery, Socioeconomic status (ρ = −0.118 [95 % CI −1.000 to −0.014], p = 0.027), and Household composition/disability (ρ = −0.203 [95 % CI −1.000 to −0.102], p < 0.001); Hand surgery and Socioeconomic status (ρ = −0.114 [95 % CI −1.000 to −0.010], p = 0.031); Otolaryngology, Housing type/transportation (ρ = −0.102 [95 % CI −1.000 to 0.001], p = 0.047), and Overall Social Vulnerability (ρ = −0.105 [95 % CI −1.000 to −0.001], p = 0.043). Multiple regression analyses reinforced these findings. ConclusionsThis study concludes that social vulnerability is predictive of, and significantly linked to, differences in distribution of surgical subspecialty and surgeon gender. Future research should investigate recruitment of a diverse surgical workforce, infrastructural barriers to care, and differences in quality of care. Key messageOur work demonstrates complex relationships between surgical subspecialist distribution, surgeon gender, and a census tract's various Social Vulnerability Indices. Thus, this research can serve to continue educating surgeons and other healthcare providers about the importance of social determinants of health in the construction of healthcare policy and practice, as well as incentivizing equitable recruitment of a diverse population of surgeons.
