VENUM (Vascular Education iN Undergraduate Medicine): a multicentre evaluation of undergraduate vascular education in the UK

INTRODUCTION

Vascular surgery is a recognised surgical subspecialty covering an array of circulatory conditions predominately affecting geriatric and diabetic patients. As such, a wide breadth of clinicians will see patients with vascular pathologies, but it is unclear how detailed their knowledge base is. Key to this is the education of medical students, which has been poorly documented during undergraduate training in the UK. VENUM aimed to establish students' perceptions of vascular surgery and their confidence in performing vascular objective structured clinical examination (OCSE) skills.

METHODS

During the academic year of 2022/2023, final-year medical students were invited to complete a JISC survey (collaborative authorship). Seventy-seven research leads were recruited to disseminate the survey. Quantitative and thematic analysis was used to assess the data.

RESULTS

In total, 240 final-year medical students completed the survey (54% female; 26 medical schools represented). Forty-five per cent of students reported never having had a vascular placement, 24% had never completed a vascular-focused clinical examination and 26% reported low confidence in performing ankle brachial pressure index measurement. An assessment of peripheral arterial disease morbidity was answered correctly in 17% of respondents compared with 92% for angina (chi-square test p<0.001). Students perceived the specialty to be non-inclusive and that early exposure to vascular surgery was required for better engagement with the specialty.

CONCLUSION

Students have experienced little exposure to vascular surgery. This may affect future recruitment to vascular surgery and overall knowledge of vascular conditions in UK-trained doctors, which may affect long-term patient management.

Financial Barriers to Surgical Conferences: A Cross-Sectional Analysis of Registration Fees

BACKGROUND

Scientific meetings provide much educational value to participants of all career stages. There is a paucity of literature surrounding the costs of attending scientific meetings and how this may affect participation, especially among trainees. The objective of this study is to assess the accessibility of surgical conferences for attendees by analyzing costs related to surgical society membership and conference registration.

METHODS

Societal membership and conference registration fee data were collected according to career stage (i.e., student, resident, fellow, and staff) for the fourteen surgical specialties recognized by the American College of Surgeons (ACS). Fees for participants from low- and middle-income countries (LMICs) and for virtual-only attendance options were also collected when available.

RESULTS

Overall, we included data from 46 surgical societies (32 North American, 14 European or global). The median conference fees for students in the member and non-member categories were 191.55 USD (IQR 42.22-320.99) and 452.40 USD (IQR 294.06-555.00), respectively, representing a 136.2% price increase if not a member. Median conference fees for residents, fellows, and staff in the member category were 65.5%, 66.9%, and 230.9% greater than that for students, respectively. Median prices for residents, fellows, and staff in the non-member category were 49.9%, 54.9%, and 49.9% greater than that for member trainees of the same category, respectively.

CONCLUSIONS

Our results highlight the substantial costs associated with attending surgical conferences, especially for trainees, representing a significant barrier to already financially burdened trainees, especially those from LMICs, smaller institutions, or less well-off backgrounds.

A decade of diversity: using statistical indices to compare neurosurgery to other surgical specialties

OBJECTIVE

Studies have demonstrated the benefits of diversity in neurosurgery. However, recruitment of minoritized groups within the neurosurgical workforce consistently lags other surgical specialties. While racial and gender demographics of neurosurgical residents are well documented, there has been minimal exploration into the multidimensional nature of diversity. The current study will evaluate the longitudinal diversity changes in neurosurgery residency programs compared with other surgical fields with validated diversity indices.

METHODS

Nationwide reports including data about resident physicians were obtained from the American Medical Association and the Association of American Medical Colleges for the academic years 2008-2021. Self-reported race, biological sex, and medical school affiliation were recorded for surgical residents in the 10 commonly recognized surgical fields. The Gini-Simpson Diversity Index was used to calculate the effective counts (ECs) of races, sexes, and medical school types for each field. A Composite Diversity Index (CDI) comprising the aforementioned diversity traits was used to calculate the percentage of characteristics upon which two randomly selected residents within each specialty would differ. CDIs were calculated for each field in every year from 2008 to 2021. Median CDIs were compared between fields using Kruskal-Wallis testing, and p values < 0.05 were deemed statistically significant.

RESULTS

Plastic surgery had the highest median sex EC (1.92, interquartile range [IQR] 1.78-1.95), indicating greater diversity, while neurosurgery had the third lowest sex EC (1.40, IQR 1.35-1.41). All surgical fields examined had fewer than 3 races effectively represented among their residents, despite there being 8 races present. Neurosurgery ranked among the top fields in effective racial diversity (EC 2.17, IQR 2.09-2.21) and medical school type diversity (EC 1.25, IQR 1.21-1.26). There were statistically significant differences in the sex, race, and school ECs between surgical specialties. While neurosurgery had a relatively low median overall diversity (CDI = 32.7, IQR 32.0-34.6), there was a consistent longitudinal increase in CDI from 2015 to 2021.

CONCLUSIONS

Neurosurgery resident physicians have become increasingly diverse in the past decade but are more homogenous than residents in other surgical fields. The continued use of diversity indices to more accurately track diversity progress over time may better inform leaders in the field of how they may best focus their equity and inclusion efforts.

Clinical stakeholder preferences for paediatric cardiac surgery outcome reporting in Australia and New Zealand

BACKGROUND

Outcome reporting is an essential element of quality assurance. Evaluation of the information needs of stakeholders of outcome reporting is limited. This study aimed to examine stakeholder preferences for the content, format, and dissemination of paediatric cardiac surgery performance data in Australia and New Zealand.

METHODS

Semi-structured interviews were completed with a purposive sample of Queensland stakeholders to evaluate their attitudes and expectations regarding reporting of paediatric cardiac surgery outcomes. The interviews were audio-recorded and transcribed. Two researchers used an interpretive description approach to analyse the transcripts qualitatively.

RESULTS

Nineteen stakeholders were interviewed including fifteen clinicians, four parents, one hospital administrator, and one consumer advocate were interviewed. Mortality was highlighted as the area of greatest interest in reports by clinical and consumer groups. The majority preferred hospital rather than individual/clinician-level reporting. Annual reports were preferred by clinicians who requested reports be distributed electronically.

CONCLUSIONS

The evidence generated from outcome reporting in paediatric cardiac surgery is highly desired by clinicians, administrators, parents, families, and advocacy groups. Clinical users prefer information to assist in clinical decision-making, while families seek personalised information at crucial time points in their clinical journey.

History of Cranial Surgery in World War I: Experience on the Italian Front

Since ancient history, men have been attempting to intervene when skull trauma occurs. The majority of traumas were always linked to war injuries, and in the modern era, the culprit was reached during World War I. Cranial traumas in wartime were very common, and consequently, physicians in wartime became particularly interested in the subject of cranial traumatology. In the following text, we want to bring to light the experience of some of the pioneers of cranial surgery in Italy during the First Great War. In fact before the war, very few medical officers had received training in central nervous system surgery. In addition, the surgical instruments for that clinical activity were inadequate and obsolete, but to deal with the medical emergency that had arisen on the front lines, the Italian government established Battlefield Medical Schools. And it is also from the reports and lectures of surgeons working on the front lines that the next generations of neurosurgeons were able to develop this surgical field into the complex and well-established surgical specialty that it is today.

Social media for patient engagement

Who better to serve as "Dr. Google" than an actual doctor? Patients often present with a list of symptoms and turn to their favorite search engine to understand their constellation of symptoms. In this editorial, we attempt to address the following key elements in surgeons' use of social media (#SoMe4Surgery) as a tool for patient engagement: marketing, demystifying and differentiating the surgical specialty, a fast track to the latest specialty-specific guidelines and recommendations, and combatting medical misinformation. The increased social media presence in the medical space can be used to improve health literacy and simplify the navigational process of one's healthcare journey. These platforms can humanize physicians, make them more accessible, and bridge the gap that sometimes exists, preventing patients from moving to their next step in care due to fear. The extent of social media use in healthcare far surpasses this brief discussion, and it is up to the individual user to exercise the appropriate uses and responsibilities regarding patient communication.

Critical elements of pediatric neuroblastoma surgery

Neuroblastoma (NB) is the most common solid extracranial malignancy of childhood with an incidence of 1 per 100,000 in the United States compromising approximately 10 % of childhood cancer. Unfortunately, patients with high-risk NG continue to have long-term survival less than 50 %. Both Children's Oncology Group and the International Society of Paediatric Oncology have demonstrated the important role of surgery in the treatment of high-risk NB. Herein, we compose the results of an extensive literature review as well as expert opinion from leaders in pediatric surgical oncology, to present the critical elements of effective surgery for high-risk neuroblastoma.

Pediatric Surgery and University

INTRODUCTION

Pediatric Surgery studies in Spanish universities are not regulated, and their situation varies significantly from one region to another.

MATERIALS AND METHODS

A descriptive study by means of a survey directly addressed to the heads of the 47 Spanish healthcare units was carried out.

RESULTS

Only 33 pediatric surgeons currently teach at the university level. Most of them are employed (associate professors) and assigned to non-surgical departments. The degree of teaching accreditation of these professionals is meager.

CONCLUSION

It is necessary to reflect deeply on the absence of our specialty in universities and, conversely, on the scarce presence of university studies and research in healthcare units.

Optimizing Surgical Performance Using Preoperative Virtual Reality Planning: A Systematic Review

BACKGROUND

Surgery is often a complex process that requires detailed 3-dimensional anatomical knowledge and rigorous interplay between team members to attain ideal operational efficiency or "flow." Virtual Reality (VR) represents a technology by which to rehearse complex plans and communicate precise steps to a surgical team prior to entering the operating room. The objective of this study was to evaluate the use of VR for preoperative surgical team planning and interdisciplinary communication across all surgical specialties.

METHODS

A systematic review of the literature was performed examining existing research on VR use for preoperative surgical team planning and interdisciplinary communication across all surgical fields in order to optimize surgical efficiency. MEDLINE, SCOPUS, CINAHL databases were searched from inception to July 31, 2022 using standardized search clauses. A qualitative data synthesis was performed with particular attention to preoperative planning, surgical efficiency optimization, and interdisciplinary collaboration/communication techniques determined a priori. Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were followed. All included studies were appraised for their quality using the Medical Education Research Study Quality Instrument (MERSQI) tool.

RESULTS

One thousand and ninety-three non-duplicated articles with abstract and full text availability were identified. Thirteen articles that examined preoperative VR-based planning techniques for optimization of surgical efficiency and/or interdisciplinary communication fulfilled inclusion and exclusion criteria. These studies had a low-to-medium methodological quality with a MERSQI mean score of 10.04 out of 18 (standard deviation 3.61).

CONCLUSIONS

This review demonstrates that time spent rehearsing and visualizing patient-specific anatomical relationships in VR may improve operative efficiency and communication across multiple surgical specialties.

Practice patterns of hepatobiliary surgery within the military

BACKGROUND

The purpose of this study is to evaluate the trends of hepatobiliary surgeries performed at military hospitals and to discuss potential implications on resident training and military readiness. While there is data to suggest centralization of surgical specialty services leads to improved patient outcomes, the military does not currently have a specific centralization policy. Implementation of such a policy could potentially impact resident training and readiness of military surgeons. Even in the absence of such a policy, there may still be a trend toward centralization of more complex surgeries like hepatobiliary surgeries. The present study evaluates the numbers and types of hepatobiliary procedures performed at military hospitals.

METHODS

This study is a retrospective review of de-identified data from Military Health System Mart (M2) from 2014 to 2020. The M2 database contains patient data from all Defense Health Agency treatment facilities, encompassing all branches of the United States Military. Variables collected include number and types of hepatobiliary procedures performed and patient demographics. The primary endpoint was the number and type of surgery for each medical facility. Linear regression was used to evaluate significant trends in numbers of surgeries over time.

RESULTS

Fifty-five military hospitals performed hepatobiliary surgeries from 2014 to 2020. A total of 1,087 hepatobiliary surgeries were performed during this time; cholecystectomies, percutaneous procedures, and endoscopic procedures were excluded. There was no significant decrease in overall case volume. The most commonly performed hepatobiliary surgery was "unlisted laparoscopic liver procedure." The military training facility with the most hepatobiliary cases was Brooke Army Medical Center.

CONCLUSION

The number of hepatobiliary surgeries performed in military hospitals has not significantly decreased over the years 2014-2020, despite a national trend toward centralization. Centralization of hepatobiliary surgeries in the future may impact residency training as well as military medical readiness.

Current Implementation of Quality Measures on American Society for Surgery of the Hand Touching Hands Project Outreach Trips

PURPOSE

As hand and upper extremity outreach trips increase, guidelines for assessing quality of care are being established. The Global Quality in Upper Extremity Surgery and Training investigators have published validated quality measures deemed to be essential for outreach trips to low and middle-income countries (LMICs). The purpose of this study was to assess baseline implementation of these quality measures across nine international hand surgery outreach sites to LMICs. Additionally, we investigated barriers and facilitators to implementing quality measures and documentation of their implementation.

METHODS

We included nine of 12 scheduled 2019 Touching Hands Project trips, excluding independent outreach and teaching mission trips without surgical logs. The team leader from each site received an online questionnaire assessing the documentation and implementation of all 22 quality measures, as well as educational efforts.

RESULTS

A total of 350 surgeries were performed in 2019 with seven reported minor complications and no major complications or mortalities. For analysis, 20 of 22 quality measures were included. Of 20 included validated quality measures, 10 were implemented across all surgical outreach sites. Two sites (Bolivia, Nepal) implemented all of the validated quality measures. Quality measures with the lowest implementation rates included ensuring availability of continuous electricity and oxygen supply with associated documentation of a backup plan. All outreach sites reported formal educational efforts.

CONCLUSIONS

Implementation of validated quality measures across surveyed outreach sites is variable, indicating an opportunity for improvement. Standardizing documentation of quality measure implementation for each site, confirming availability of resources, increasing accountability by the visiting teams, and fostering stronger relationships with local health care, may increase quality measure implementation and improve quality health care delivery and patient safety in LMICs.

CLINICAL RELEVANCE

Benchmarking the implementation of validated quality measures across hand surgical outreach trips provides an opportunity to improve the quality of health care delivered during future hand surgical outreach efforts.

Research and Publication Trends in Pediatric Surgery in Latin America: A Bibliometric and Visual Analysis from 2012 to 2021

INTRODUCTION

Pediatric surgery is a developing specialty with increasing volume in Latin America. However, the research and scientific activity trends carried out in this region in recent years are unknown. This study aimed to analyze and visualize Latin American research in pediatric surgery from 2012 to 2021.

MATERIAL AND METHODS

Bibliometric cross-sectional study of scientific articles on pediatric surgery published by Latin American authors from 2012 to 2021 in Scopus was performed. Statistical and visual analysis was performed with R programming language and VOS viewer.

RESULTS

449 articles were found. Observational studies (44.7%; n = 201), case reports (20.4%; n = 92) and narrative reviews (11.4%; n = 51) were found to be the most common study designs. The published articles were predominantly monocentric (73.1%; n = 328), only 17% (n = 76) involved authors from 2 or more countries, and mostly there was no collaboration with high-income countries (80.6%; n = 362). The Journal of Pediatric Surgery was the journal with the highest volume of articles published (n = 37). The most used terms were Laparoscopy, Complications, and Liver Transplantation, and the countries with the highest number of articles published were Brazil and Argentina.

CONCLUSIONS

This study found a progressive increase in the scientific activity of Latin authors in pediatric surgery from 2012 to 2021. The evidence produced was mainly from observational studies and case reports, predominantly conducted in Brazil. Multinational and international collaboration was low; the most frequent topics of interest were laparoscopy and minimally invasive surgery.

Undeserved authorship in surgical research: an underestimated bias with potential side effects on academic careers

The incidence of courtesy authorship in research over time has probably increased due to the enormous pressure to publish to increase the bibliometric indexes necessary to achieve an academic role. The aim of this survey was to quantify and characterize this research malpractice among a very selected group of surgeons from different surgical specialties belonging to the European Association of Surgery (ESA). E-mail addresses for the invitation to take part to the survey were collected by the Twenty-eighth Annual Meeting final program. Five-item were designed and developed by the authors using an online platform. Eighty-six members from 21 countries completed the survey (female/male ratio: 0.09). In the last 10 years, almost half of the responders (41, 47.7%, 37 academics) have included colleagues for courtesy authorship. The most common reason of courtesy authorships was to support the academic career of another researcher (62.5%). Other reasons were fear of retaliation (12.5%), reciprocal authorship (12.5%) or support for a partner (10%). This survey showed that undeserved authorship is sadly confirmed to be a common research misconduct across any countries and medical specialties, even among a very selected group of surgeons with international reputation irrespective of the academic position.

Attitudes Toward Surgical Innovation Research in the Pediatric Surgery Fellowship Match

INTRODUCTION

Pediatric surgery applicants are increasingly pursuing research in non-traditional fields including surgical innovation. This study aims to evaluate the relative value that pediatric surgeons involved in fellow selection place on innovation experience compared to traditional research.

METHODS

A cross-sectional web-based survey of American Pediatric Surgical Association members involved in the selection of pediatric surgical fellows was conducted. Respondents reported their own innovation experience and were asked to identify valuable traits of applicants who completed an innovation fellowship. They rated the value of traditional research metrics including publications, presentations, and advanced degrees compared to patents and other innovation-related metrics. Comparisons were made between those with and without innovation experience with respect to gender, years in practice, and institutional role.

RESULTS

One hundred thirty respondents were involved in pediatric surgery fellow selection. Innovation work was felt to be equal to or more valuable than basic science by 75% of respondents (84% vs. clinical/outcomes, 93% vs. other non-traditional, 72% vs. other clinical fellowships). Commonly cited concerns included "fewer publications" (21%) and "preoccupation with financial reward" (19%). The most valuable innovation-related metrics were "developing a novel surgical procedure" (67%) and "developing a novel device" (58%). When asked if the respondent would advise a junior resident to pursue an innovation fellowship, 49% would, 9% would not, and 43% were unsure. Seventeen percent expressed concern for match success.

CONCLUSION

Innovation experience is generally viewed positively by pediatric surgeons involved in fellow selection. However, applicants and mentors would benefit from focusing on traditional academic outputs to ensure competitiveness.

Women in Irish urology: An examination of female representation amongst attendees of the Irish Society of Urology annual meeting (2008-2020)

BACKGROUND

There is underrepresentation of women at surgical conferences. We examine the representation of women in Irish urology by looking at gender balance within the Irish Society of Urology (ISU) conference.

AIMS

ISU programmes over thirteen years from 2008 to 2020 were assessed and female representation in session chairs, guest speakers, poster and oral presentations identified. Gender distributions of authors for each year was examined. To investigate changes in female representation temporally, the period of this study (2008-2020) was subdivided and compared: 2008-2013 and 2014-2020.

RESULTS

76 sessions were presided over by 138 chairs, of which 6 (4.3%) were female. Eight conferences had zero female chairs. 62 guest lectures were given, 6 (9.6%) by women. Of total 340 poster and 434 oral presentations, women delivered 24.9% (0-47.5%) of posters and 31.6% (10.3-59.4%) of oral presentations. We found no significant difference in the percentage of female poster presentations between the time periods 2008-2013 (m = 18.2, sd = 13.7) and 2014-2020 (m = 34.3, sd = 17.8), t(11) = -1.4, p > 0.05. However, we found a significant difference in the percentage of female oral presentations between the periods 2008-2013 (m = 18.7, sd = 14.2) and 2014-2020 (m = 40.6, sd = 14.5), t(11) = -2.8, p < 0.05.

CONCLUSIONS

Our study is the second to examine female representation in Irish urology. Session chairs and guest speakers were grossly overrepresented by males as were oral and poster presentations. Despite lacking female influence overall, in more recent years there was an increased representation of women. Societies should strive to increase female representation, as this perpetuates a positive feedback loop, encouraging future female trainees to pursue urological surgery.

[A survey on surgical training during residency in Sweden - description of the current state]

Practical training for new surgeons differs between institutions, and standards are mostly lacking. The largest problems seem to occur during the first years, when novices begin their specialty training, (specialisttjänstgöring in Swedish). A large number of scientific publications are available, but the they are usually limited to one specific procedure or one surgical specialty, and the results are rarely applied in practice. Scientifically validated and systematic methods for basic training outside the operating room have been called for over the last decade, but the main part of the training still takes place during surgery on patients. In order to evaluate the practising of manual skills among doctors doing their training within surgical specialties, a survey with fourteen questions was carried out. The results show shortcomings that seem easy to remedy in the short term, but long term studies on the subject are required to better understand and systematize surgical training.

American Academy of Orthopaedic Surgeons Clinical Practice Guideline Summary on the Treatment of Clavicle Fractures

Treatment of Clavicle Fractures Evidence-Based Clinical Practice Guideline is based on a systematic review of published studies examining the diagnosis and treatment of clavicle fractures. This guideline contains four recommendations and 10 options to assist orthopaedic surgeons and any other qualified healthcare professionals with determining the treatment of isolated clavicle fractures based on the best current available evidence. It is also intended to serve as an information resource for healthcare professionals and developers of practice guidelines and recommendations. In addition to providing pragmatic practice recommendations, this guideline also highlights gaps in the literature and informs areas for future research and quality measure development. This guideline has been endorsed by the Orthopaedic Trauma Association, the American Shoulder and Elbow Surgeons, and the American Society of Shoulder and Elbow Therapists.

How many cases do instructor class pediatric surgeons need to experience to be an independent operator in performing advanced endoscopic surgery? A nationwide survey to establish an ideal curriculum for pediatric endoscopic surgery in Japan

PURPOSE

To ensure the safe spread of pediatric endoscopic surgery, it is essential to build a training curriculum, and a survey of the current situation in Japan is necessary. The present study assessed an efficient training curriculum by clarifying instructor class pediatric surgeons' experiences, including autonomy when performing advanced endoscopic surgeries.

METHODS

An online nationwide questionnaire survey was conducted among pediatric surgeons who had Endoscopic Surgical Skill Qualification (ESSQ) and board-certified instructors who had skills comparable to ESSQ. We assessed participants' training experience, opinions concerning the ideal training curriculum, and the correlation between surgical experience and the level of autonomy. The Zwisch scale was used to assess autonomy.

RESULTS

Fifty-two participants responded to the survey (response rate: 86.7%). Only 57.7% of the respondents felt that they had received sufficient endoscopic surgery training. Most respondents considered an educational curriculum for endoscopic surgery including off-the-job training essential during the training period. Autonomy had been acquired after experiencing two to three cases for most advanced endoscopic surgeries.

CONCLUSION

This first nationwide survey in Japan showed that instructor class pediatric surgeons acquired autonomy after experiencing two to three for most advanced endoscopic surgeries. Our findings suggest that training, especially off-the-job training, has been insufficient.

Artificial intelligence for the vascular surgeon

In recent years, artificial intelligence (AI) has permeated different aspects of vascular surgery to solve challenges in clinical practice. Although AI in vascular surgery is still in its early stages, there have been promising developments in its applications to vascular diagnosis, risk stratification, and outcome prediction. By establishing a baseline knowledge of AI, vascular surgeons are better equipped to use and interpret the data from these types of projects. This review aims to provide an overview of the fundamentals of AI and highlight its role in helping vascular surgeons overcome the challenges of clinical practice. In addition, we discuss the limitations of AI and how they affect AI applications.

Gender Bias in Clinical Trial Enrollment: Female Authorship Matters

BACKGROUND

Despite initiatives to promote equal enrollment of human subjects in clinical trials, females continue to be underrepresented. The goal of this work is to determine if female enrollment in human clinical trials published in 3 high-impact journals from 2015 to 2019 is correlated with gender of first and/or senior authors.

METHODS

Clinical trials published in the Journal of the American Medical Association (JAMA), The Lancet, and the New England Journal of Medicine (NEJM) from January 1, 2015, to December 31, 2019, were reviewed. Trials were excluded for ongoing enrollment, sex-specific disease research, or author name without gender assignment. One-sample χ2 pairwise comparisons and two-tailed proportion tests on the proportion of females between gender author pairings were done overall and for each subset analysis.

RESULTS

In total, 1,427 articles enrolled a total of 2,104,509 females and 2,616,981 males (44.6% vs. 55.4%, P ≤ 0.0001) in clinical trials. Overall, more females were enrolled if both first and senior authors were female (51.7% vs. 48.3%, P ≤ 0.0001). Proportion of females enrolled decreased with the following first and senior author pairings: female-male (48.9%), male-female (48.6%), and male-male (40.5%, P ≤ 0.0001 compared to female-female authorship). Greater female enrollment in clinical trials with female-female compared to male-male authorship persisted in subset analyses by funding source, phase, randomization for study participants, drug and/or device trial, and geographic location. Female enrollment was higher in 3 surgical specialties: neurosurgery (all authors: 52%, P ≤ 0.01), ophthalmology (all authors: 53.6%, P ≤ 0.0001), and surgery (all authors: 54.4%, P ≤ 0.0001). The majority of surgical specialties did not publish trials with female-female authorship but when stratifying by author gender pairing, surgical oncology had the highest female enrollment with female-female authorship (98.4%, P ≤ 0.0001).

CONCLUSIONS

Female authorship of clinical trial publications, specifically having both first and senior authors as female, was correlated with higher female enrollment in clinical trials when compared to male authorship and endured with multiple subset analyses.

Exploring the perception of venous disease within vascular surgery

BACKGROUND

Biases and gender disparities influence career pathways within medicine, and vascular surgery is no exception. Venous disease comprises an estimated 1% to 3% of total health care expenditures. However, its value among vascular surgeons is poorly understood. This study aims to investigate the factors that influence vascular surgeons' current perceptions of superficial and deep venous disease treatments.

METHODS

An anonymous survey was distributed electronically to practicing vascular surgeons in December 2021. The respondents were stratified by gender and practice breakdown. A venous-heavy practice was defined as a practice with venous work comprising ≥25% of the total volume. Changes in practice patterns over the respondent's career were also explored. Descriptive, univariate, and multivariate analyses were performed using STATA (StataCorp).

RESULTS

A total of 315 practicing vascular surgeons responded, with 81.5% from the United States. Their mean age was 46.6 ± 9.6 years, and most identified as men (63.3%). The race and ethnicity breakdown was as follows: White (non-Hispanic), 63.0%; Asian or Asian Indian, 17.1%; Hispanic, Latinx, or Spanish, 8.4%; Black, 1.6%; and unknown, 9.9%. The practice settings were academic for 47.0%, private practice for 26.5%, hospital employed for 23.3%, and other for 3.2%. The female respondents were significantly younger (P < .0001), with fewer years in practice (P < .0001) and were more likely to perceive a gender bias within a career encompassing venous disease compared with the male respondents (P = .02). Of the 315 participants, 143 (45.4%) had a venous-heavy practice. No differences were found in age or gender between the venous-heavy and venous-light practices. Those with a venous-heavy practice had significantly more years in practice statistically (P = .02), had sought more venous training after graduation (P < .0001), were more likely to be in private practice (P < .0001), and were more likely to desire a practice change (P = .001) compared with those with a venous-light practice. Overall, 74.3% of respondents indicated that venous work might be less "valued" than arterial work in the field of vascular surgery. On multivariable regression, the predictors for the perception of venous work being less valued were female gender (odds ratio, 2.01; 95% confidence interval, 1.14-4.03) and completion of a vascular surgery fellowship (odds ratio, 2.0; 95% confidence interval, 1.15-3.57).

CONCLUSIONS

Vascular surgeons overwhelmingly perceived the management of venous disease to be of less value than that of arterial disease, particularly by women and fellowship-trained vascular surgeons. The prevalence of venous disease, as measured by its proportion of the U.S. healthcare budget, cannot be overstated. Thus, efforts to elevate the importance of chronic venous disease within the scope of vascular surgery practices are essential to ensure patients are provided with appropriate specialty care.

Hospital Variation in Mortality After Inpatient Pediatric Surgery

OBJECTIVE

The aim was to determine the association between risk adjusted hospital perioperative mortality rates, postoperative complications, and failure to rescue (FTR) after inpatient pediatric surgery.

BACKGROUND

FTR has been identified as a possible explanatory factor for hospital variation in perioperative mortality in adults. However, the extent to which this may be the case for hospitals that perform pediatric surgery is unclear.

METHODS

The Pediatric Health Information System database (2012-2020) was used to identify patients who underwent one of 57 high-risk operations associated with significant perioperative mortality (n=203,242). Academic, pediatric hospitals (n=48) were stratified into quintiles based on risk adjusted inpatient mortality [lower than average, quintile 1 (Q1); higher than average, quintile 5 (Q5)]. Multivariable hierarchical regression was used to evaluate the association between hospital mortality rates, complications, and FTR.

RESULTS

Inpatient mortality, complication, and FTR rates were 2.3%, 8.8%, and 8.8%, respectively. Among all patients who died after surgery, only 34.1% had a preceding complication (Q1, 36.1%; Q2, 31.5%; Q3, 34.7%; Q4, 35.7%; Q5, 32.2%; trend test, P =0.49). The rates of observed mortality significantly increased across hospital quintiles, but the difference was <1% (Q1, 1.9%; Q5; 2.6%; trend test, P <0.01). Relative to Q1 hospitals, the odds of complications were not significantly increased at Q5 hospitals [odds ratio (OR): 1.02 (0.87-1.20)]. By comparison, the odds of FTR was significantly increased at Q5 hospitals [OR: 1.60 (1.30-1.96)] with a dose-response relationship across hospital quintiles [Q2-OR: 0.99 (0.80-1.22); Q3-OR: 1.26 (1.03-1.55); Q4-OR: 1.33 (1.09-1.63)].

CONCLUSIONS

The minority of pediatric surgical deaths are preceded by a postoperative complication, but variation in risk adjusted mortality across academic, pediatric hospitals may be partially explained by differences in the recognition and management of postoperative complications. Additional work is needed to identify children at greatest risk of postoperative death from perioperative complications as opposed to those at risk from pre-existing chronic conditions.

Selective Publication within Vascular Surgery: Characteristics of Discontinued and Unpublished Randomized Clinical Trials

BACKGROUND

Discontinued and unpublished randomized clinical trials (RCTs) are common resulting in biased publication and loss of potential knowledge. The magnitude of selective publication within vascular surgery remains unknown.

METHODS

RCT relevant to vascular surgery registered (01/01/2010-10/31/2019) on ClinicalTrials.gov were included. Trials ending normally with conclusion of participant treatment and examination were considered completed whereas discontinued trials stopped early. Publications were identified through automatically indexed PubMed citations on ClinicalTrials.gov or manually identified on PubMed or Google Scholar >30 months after the completion date, the date the final participant was examined, allowing time for publication.

RESULTS

Of 108 RCT (n = 37, 837), 22.2% (24/108) were discontinued, including 16.7% (4/24) stopped prior to and 83.3% (20/24) after starting enrollment. Only 28.4% of estimated enrollment was achieved for all discontinued RCT. Nineteen (79.2%) investigators provided a reason for discontinuation, which most commonly included poor enrollment (45.8%), inadequate supplies or funding (12.5%), and trial design concerns (8.3%). Of the 20 trials terminated following enrollment, 20.0% (4/20) were published in peer-reviewed journals and 80.0% (16/20) failed to reach publication. Of the 77.8% trials completed, 75.0% (63/84) were published and 25.0% (21/84) remain unpublished. In a multivariate regression of completed trials, industry funding was significantly associated with decreased likelihood of peer-reviewed publication (OR = 0.18, (95% CI 0.05-0.71), P = 0.01). Of the discontinued and completed trials remaining unpublished, 62.5% and 61.9% failed to report results on ClinicalTrials.gov, respectively, encompassing a total of 4,788 enrollees without publicly available results.

CONCLUSIONS

Nearly 25% of registered vascular RCT were discontinued. Of completed RCT, 25% remain unpublished with industry funding associated with decreased likelihood of publication. This study identifies opportunities to report all findings for completed and discontinued vascular surgery RCT, whether industry sponsored, or investigator initiated.
