Virtual Reality–Enabled Resident Education of Lateral-Access Spine Surgery

OBJECTIVELateral access spine surgery has many benefits, but adoption has been limited by a steep learning curve. Virtual reality (VR) is gaining popularity and lends itself as a useful tool in enhancing neurosurgical resident education. We thus sought to assess if VR-based simulation could enhance the training of neurosurgery residents in lateral spine surgery. METHODSNeurosurgery residents completed a VR-based lateral spine module on lateral patient positioning and performing lateral lumbar interbody fusion (LLIF) using the PrecisionOS VR system on the Meta Quest 2 headset. Simulation occurred 1x/week every other week for a total of 3 simulations over 6 weeks. Pre- and post-intervention surveys as well as intra-simulation performance metrics were assessed over time. RESULTSThe majority of resident participants showed improvement in performance scores, including an automated PrecisionOS precision score, number of X-rays used within the simulation, and time to completion. All participants showed improvement in comfort with anatomic landmarks for lateral access surgery, confidence performing lateral surgery without direct supervision, and assessing fluoroscopy in spine surgery for hardware placement and image interpretation. Participant perception on the utility of VR as an educational tool also improved. CONCLUSIONVR-based simulation enhanced neurosurgical residents’ ability to understand lateral access surgery. Immersive surgical simulation resulted in improved resident confidence with surgical technique and workflow, perceived improvement in anatomical knowledge, and simulation performance scores. Trainee perceptions on virtual simulation and training as a curriculum supplement also improved following completion of VR training.

Examination Approaches to Brachial Plexus Injury for Neurosurgical Residents.

Brachial plexus injury is a severe peripheral nerve injury that affects the upper extremities and causes functional damage and disability. A detailed and accurate clinical examination is required to accurately localise the site of injury. This video manuscript aims to provide guidelines for the structured assessment of a patient with brachial plexus injury, specifically tailored to Malaysian medical students and trainees. A video demonstrating the examination of the brachial plexus was made. This video, created at the School of Medical Sciences at Universiti Sains Malaysia (USM), demonstrates the proper examination technique for brachial plexus. We hope that this video will help students and young doctors evaluate patients with brachial plexus injury and reach accurate localisation of the injury.

Reducing the Gap in Neurosurgical Education in LMICs: A Report of a Non-Profit Educational Program

Central to neurosurgical care, neurosurgical education is particularly needed in low- and middle-income countries (LMICs), where opportunities for neurosurgical training are limited due to social and economic constraints and an inadequate workforce. The present paper aims (1) to evaluate the validity and usability of a cadaver-free hybrid system in the context of LMICs and (2) to report their learning needs and whether the courses meet those needs via a comprehensive survey. From April to November 2021, a non-profit initiative consisting of a series of innovative cadaver-free courses based on virtual and practical training was organized. This project emerged from a collaboration between the Young Neurosurgeons Forum of the World Federation of Neurological Societies (WFNS), the NIHR Global Health Research Group on Neurotrauma, and UpSurgeOn, an Italian hi-tech company specialized in simulation technologies, creator of the UpSurgeOn Box, a hyper-realistic simulator of cranial approaches fused with augmented reality. Over that period, 11 cadaver-free courses were held in LMICs using remote hands-on Box simulators. One hundred sixty-eight participants completed an online survey after course completion of the course. The anatomical accuracy of simulators was overall rated high by the participant. The simulator provided a challenging but manageable learning curve, and 86% of participants found the Box to be very intuitive to use. When asked if the sequence of mental training (app), hybrid training (Augmented Reality), and manual training (the Box) was an effective method of training to fill the gap between theoretical knowledge and practice on a real patient/cadaver, 83% of participants agreed. Overall, the hands-on activities on the simulators have been satisfactory, as well as the integration between physical and digital simulation. This project demonstrated that a cadaver-free hybrid (virtual/hands-on) training system could potentially participate in accelerating the learning curve of neurosurgical residents, especially in the setting of limited training possibilities such as LMICs, which were only worsened during the COVID-19 pandemic.

An assessment of the long-term impacts of the coronavirus disease 2019 pandemic on academic neurosurgery.

The goal of this study was to survey residents, fellows, and residency program leadership to assess the long-term impacts of the coronavirus disease 2019 (COVID-19) on residency training by using a structured survey methodology. A survey was distributed to US neurosurgical residents and fellows (n = 2085) as well as program directors (PDs) and chairs (n = 216) in early 2022. Bivariate analysis was performed to identify factors associated with a decreased likelihood of pursuing a career in academic neurosurgery because of the pandemic, a perception that surgical skills preparation was negatively impacted, personal financial concerns, and a preference for remote education. Significant differences in the bivariate analysis underwent further multivariate logistic regression analysis to evaluate for predictors of these outcomes. An analysis of complete surveys from 264 residents and fellows (12.7%) and 38 PDs and chairs (17.6%) was performed. Over half of the residents and fellows (50.8%) believed that their surgical skills preparation was negatively impacted by the pandemic, and a notable proportion believed that they were less likely to go into academics because of the pandemic's impact on their professional (20.8%) and personal (28.8%) life. Those less likely to pursue academics were more likely to report that work-life balance did not improve (p = 0.049), personal financial concerns increased (p = 0.01), and comradery among residents (p = 0.002) and with faculty (p = 0.001) did not improve. Residents who indicated they were less likely to go into academics were also more likely to have been redeployed (p = 0.038). A large majority of PDs and chairs indicated that the pandemic resulted in financial setbacks for their departments (71.1%) and institutions (84.2%), with 52.6% reporting reduced faculty compensation. Financial setbacks at the institutional level were associated with a worsened opinion of hospital leadership (p = 0.019) and reports of a reduced quality of care for non-COVID-19 patients (p = 0.005) but not from faculty member losses (p = 0.515). A plurality of trainees (45.5%) reported a preference for a remote format for educational conferences compared to 37.1% who disagreed. This study provides a cross-section of the pandemic's impact on academic neurosurgery, highlighting the importance of continued efforts to assess and address the long-term consequences of the COVID-19 pandemic for US academic neurosurgery.

Women in neurosurgery: a cross-sectional demographic study of female neurosurgery residents in the United States.

Over the past several decades, the number of women applying to medical school has increased significantly. However, parallel recruitment and retention of women in the field of neurosurgery continues to lag. The aim of this study was to identify the ratio and trend of female neurosurgery residents to the total number of residents during the past 7 years across all US neurosurgery residency programs. The authors conducted a cross-sectional demographic study investigating the ratio of female neurosurgery residents to the total number of neurosurgery residents across US neurosurgical programs from 2016 to 2022. Using the Fellowship and Residency Electronic Interactive Database, all neurosurgical residency programs in the US were collected. Data were further divided into postgraduate years 1-7 to dissect the data collection per residency year. One hundred fourteen programs were included in the study. The number of female neurosurgery residents was 71 (29.8%) in 2022, 58 (25.2%) in 2021, 65 (27.9%) in 2020, 62 (27.3%) in 2019, 46 (21.4%) in 2018, 33 (15.2%) in 2017, and 34 (15.9%) in 2016. The trend line showed a significant increase using the Mann-Kendall test (p = 0.035). The total number of international medical graduate (IMG) female neurosurgery residents was 3 (4.2%) in 2022, 4 (6.9%) in 2021, 3 (4.6%) in 2020, 1 (1.6%) in 2019, 1 (2.2%) in 2018, 1 (3%) in 2017, and 2 (5.9%) in 2016. The number of women matching into neurosurgery residency programs is modestly increasing, especially for IMG women. Future steps toward fewer gender disparities should focus on career advancement and leadership diversification in organized and academic neurosurgery.

Probing artificial intelligence in neurosurgical training: ChatGPT takes a neurosurgical residents written exam

IntroductionArtificial Intelligence tools are being introduced in almost every field of human life, including medical sciences and medical education, among scepticism and enthusiasm. Research questionto assess how a generative language tool (Generative Pretrained Transformer 3.5, ChatGPT) performs at both generating questions and answering a neurosurgical residents’ written exam. Namely, to assess how ChatGPT generates questions, how it answers human-generated questions, how residents answer AI-generated questions and how AI answers its self-generated question. Materials and methods50 questions were included in the written exam, 46 questions were generated by humans (senior staff members) and 4 were generated by ChatGPT. 11 participants took the exam (ChatGPT and 10 residents). Questions were both open-ended and multiple-choice.8 questions were not submitted to ChatGPT since they contained images or schematic drawings to interpret. Resultsformulating requests to ChatGPT required an iterative process to precise both questions and answers. Chat GPT scored among the lowest ranks (9/11) among all the participants). There was no difference in response rate for residents’ between human-generated vs AI-generated questions that could have been attributed to less clarity of the question. ChatGPT answered correctly to all its self-generated questions. Discussion and conclusionsAI is a promising and powerful tool for medical education and for specific medical purposes, which need to be further determined. To request AI to generate logical and sound questions, that request must be formulated as precise as possible, framing the content, the type of question and its correct answers.

Sociodemographics Impact Competitiveness in the Neurosurgical Match: Survey Results

BackgroundThe Neurosurgical Match involves selecting future neurosurgeons who will comprise the future national workforce, based on a competitive ranking process against other applicants. We aimed to identify which sociodemographic and academic factors influence competitiveness and rank position in The Match. MethodsA Council of State Neurosurgical Societies survey was distributed to current United States neurosurgical residents. The primary outcome measure was self-reported rank position of matched program. Variables queried included sociodemographic and academic metrics. Fisher’s exact, logistic regression, and t-tests were performed. ResultsFrom the 72 responses, there was a median United States Medical Licensing Exam (USMLE) Step 1 score of 248, 34.7% were Alpha Omega Alpha inductees, 77.8% completed one-to-three sub-internship rotations, median number of publications was 5, and 13.9% of respondents had PhDs. Sociodemographic analysis demonstrated that 69.4% were male and 30.6% were female. Applicants with a home-neurosurgery program or of female gender had statistically significantly higher odds of matching into a top three program on their rank list (OR 9 and OR 6, respectively). Females exhibited similar mean, but less variance, compared to male respondents for USMLE Step 1 scores and number of publications. Of those with a top three program match, respondents were more likely to agree that the home program supported his/her pursuance of neurosurgery. ConclusionsTwo sociodemographic factors were independently associated with high match rank: presence of home-neurosurgery program and female gender (OR 9 and 6, respectively). Female respondents reported consistently strong academic metrics (similar mean to males, but less variance compared to males).

Effect of online public domain representation in neurosurgical resident recruitment and decision-making

OBJECTIVE Over the past 20 years, female representation in neurosurgical residency programs has steadily increased. Still, the number of Black women and Black neurosurgical residents overall has remained stagnant. The authors aimed to understand the factors that led to this stagnation and how online public domain representation informs current and upcoming resident recruitment and decision-making. METHODS The authors performed a retrospective study using the following public domain sources: Doximity, neurosurgical residency program websites, and LinkedIn. The authors collected data from all neurosurgery residents who matriculated into a US neurosurgical residency program from 2015 to 2022. Variables, including name, race, gender, year of matriculation, medical school, and undergraduate institution, were recorded. RESULTS The authors analyzed resident data from 110/113 (97.3%) US neurological surgery residency programs. Of these programs, 106 (96.4%) matriculated and retained ≥ 1 female resident over the study period. There were 408 (22.6%) female neurosurgical residents, with 37 (33.6%) programs accounting for 57.8% of all female neurosurgical residents. For those states with a female resident, the lowest percentage of female residents by state was in Iowa (6.25%) and the highest was in New Hampshire (50%). Of all programs, 60 (54.5%) matriculated and retained ≥ 1 Black resident over the study period. There were 88 (4.9%) Black neurosurgical residents, with 19 (17.3%) programs accounting for 55.7% of all Black neurosurgical residents. For those states with a Black resident, the lowest percentage of Black residents by state was in Maryland (2.0%) and the highest was in Arkansas (23.1%). CONCLUSIONS Recruiting and retaining female and Black residents has increasingly become a focus of neurosurgical programs across the country. The authors’ data show that female and Black residents overwhelmingly choose to apply to and matriculate into programs that demonstrate a commitment to diversity via their online presence. Programs wishing to recruit more diverse residents should make efforts to relay their dedication to diversity, inclusion, and performance through their online presence.

Trends in successfully matched neurosurgery residency applicants.

The United States Medical Licensing Examination (USMLE) Step 1 recently transitioned to a pass/fail outcome, renewing interest in how programs select neurosurgical residents. This study investigates the association between match status and key academic metrics over time. Data are from the National Resident Matching Program from 2009 to 2022 for matched and unmatched US allopathic (MD) seniors. Investigated metrics included the mean number of contiguous ranks; mean number of distinct specialties ranked; mean USMLE Step 1 and Step 2 Clinical Knowledge (CK) scores; mean number of abstracts, presentations, and publications; mean number of research, work, and volunteer experiences; Alpha Omega Alpha status; attendance at a top 40 NIH-funded institution; PhD degree; and other degree. Multiple linear regression without an interaction term was used to evaluate how these have varied between the two groups during the study period and whether there is a difference between unmatched and matched MD seniors applying for a neurosurgical residency. Multiple linear regression with an interaction term was then used to test whether the difference in variables between the two groups changed over time. Regardless of match status, MD senior neurosurgical residency applicants exhibited an increase in USMLE Step 1 and 2 scores; average research experiences; abstracts, presentations, and publications; and work and volunteer experiences (p < 0.001). The percentage of applicants from a top 40 NIH-funded school decreased (p = 0.018), and the percentage who held an additional degree increased (p = 0.007). Between groups, there were significant differences in all categories except work experiences and other degree obtained. Over time, the difference between USMLE Step 2 scores between matched and unmatched seniors diminished (p = 0.027); in contrast, the difference in abstracts, presentations, and publications between the two groups increased over time (p < 0.001). From 2009 to 2022, neurosurgical residency applicants grew in their achievements across many metrics. In the advent of Step 1 becoming pass/fail, this study suggests that Step 2 is not viewed by programs as an adequate replacement. However, the Step 1 grading transition may serve as an opportunity for other factors to be considered that may better predict success in neurosurgical residency.

Assessing the state of LGBTQ+ diversity and inclusion in neurosurgery

OBJECTIVE The aim of this study was to assess the diversity of neurosurgeons in terms of lesbian, gay, bisexual, transgender, and/or queer (LGBTQ+) gender and sexual minority status using the Graduation Questionnaire (GQ) as the single nationalized source of LGBTQ+ identification. Additionally, inclusivity was assessed through interviews by residents and attendings in the field. METHODS First, a PRISMA literature review was conducted and independently reviewed by two authors on studies involving LGBTQ+ representation in neurosurgery from PubMed, Web of Science, and Google Scholar. Then, aggregate responses of 16,901 participants’ sexual and gender identities from the GQ administered between 2016 and 2022 were compiled. To statistically analyze the response frequencies, the authors performed a chi-square analysis. Finally, interviews were conducted with individuals who identify as LGBTQ+ and are currently neurosurgical residents or attendings. Direct invitations were extended to participate in interviews, and all participants gave informed consent prior to the interview. Interviews were conducted using standardized questions and were video recorded. RESULTS Two studies were identified by literature review that referenced the LGBTQ+ community in neurosurgery. A GQ chi-square analysis comparing neurosurgical with nonneurosurgical LGBTQ+ identification proved statistically insignificant (p = 0.65). More broad analysis of majority sexual and gender identification (heterosexual and cisgendered) compared with the total gender and sexual minority group also proved statistically insignificant (p = 0.32) in response frequency. Five interviews, including 4 residents and 1 attending, provided several overarching themes including self-identification as an invisible minority, self-limiting behavior to ensure inclusion, and LGBTQ+ status as a direct departure from the stereotypical neurosurgeon. CONCLUSIONS Results from the GQ analysis indicate that neurosurgery is achieving LGBTQ+ diversity of its incoming members comparable to that of other fields in medicine. However, qualitative data from the interviews and a lack of specific literature indicate that despite obtaining diversity, inclusion of LGBTQ+ neurosurgeons and trainees is lacking.

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 &lt; 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.

Abstract 240: Factors Affecting Selection of TraineE for Neurointervention (FASTEN)

Introduction Neurointervention has become one of the most competitive specialties in the United States due to the limited number of training spots, and a larger pool of applicants from different backgrounds: neurosurgery, neurology, and radiology. The training standards are continuously updated to ensure solid learning experiences, which ultimately factors in better outcomes and fewer complications. There is a move towards a structured competency assessment of training requirements via collaboration among several professional societies. However, the substantial drivers of candidate selection by program directors (PDs) have not been fully established yet. The goal of our study is to investigate the factors influencing the selection of fellowship candidates. Methods We distributed a 52‐question electronic survey via REDCap to 93 PDs. The questionnaire was divided into 5 categories: program characteristics; candidate demographics; educational credentials; personal traits; and research and extracurricular activities. The PDs were then asked to rank 5 pre‐selected factors from across all 5 categories. Each category included a subset of multiple‐choice questions to be graded as indicated for each category. Characteristics for these categories were scored from a range of 1 through 10 and means with standard deviations (SD) were calculated for each characteristic. Results Of the 93 PDs surveyed, 55 PDs filled the survey with a response rate of 59.1%. As per the programs’ characteristics, Neurosurgery was the most involved specialty in running the training programs (69.1%), followed by neurology (38.2%), and radiology (30.9%). Most programs were based in academic hospitals (87.3%, n=48/55). The most important criterion for candidate’s demographic characteristics was the need for visa sponsorship, followed by career gap and number of years from graduation from residency program, as summarized in Figure 1A. The most important criteria for educational credentials were being a graduate from a neurosurgical residency program (5.4 ± 2.9), and the institution where the candidate’s residency training is/was based (5.4 ± 2.5). Regarding the candidate’s personal traits, assessment by faculty members at the interview had the highest score (8.9 ± 1). In terms of research and extracurricular activities, fluency in English had the highest score (7.2 ± 1.9), followed by the number of peer‐reviewed/PubMed‐indexed publications (6.4 ± 2.2). Ranking of a final set of 5 characteristics from across all categories is summarized in Figure 1B, with knowledge of the candidate being the single most important contributing factor. Conclusion Neurointerventional training is open to candidates in neurosurgery, neurology, and radiology. To our knowledge, our survey is the first to investigate the factors that might be implicated in the final decision made by PDs when choosing the future neurointerventional trainee, including demographic, educational, research and extracurricular activities.

OTHER-07 NEUROSURGICAL ONCOLOGY CAPACITY IN KENYA: RESULTS FROM A NATIONWIDE SURVEY OF CONSULTANTS AND RESIDENTS.

Abstract Neurosurgical oncology services (NOS) in Kenya have grown in tandem with resident training programs yet little is known objectively on current capacity and challenges. A 37-item electronic survey was distributed to neurosurgical consultants and residents practicing in Kenya. Among 49 respondents [27 consultants (69% national response rate), 22 residents; median age of 36 – 40; 51% practice &amp;lt; 5 years], 100% and 88% had access to CT scan and MRI brain respectively. 57% performed more than 40 cranial tumor surgeries annually and 48/49 (98%) perform oncology cases on a “regular basis”. Radiotherapy, chemotherapy, and pathology are performed within the respondents’ institutions in 63%, 65% and 61% of surveys, while the rest are sent out. 45 (96%) utilize an operating microscope, and 8 (17%) have an ultrasonic aspirator. Palliative care services are available for 45 (92%). 41 (84%) “agree” or “strongly agree” that delays in referrals between specialties are a major challenge to practice. 38 (78%) “agree” or “strongly agree” that treatment abandonment is also a major challenge. 49% participate in a tumor registry however major barriers to conducting research included lack of funding and protected research time. Having a mentor is perceived as the greatest facilitator for conducting research. No respondents enrolled any patient in a clinical oncology trial during the past year yet nearly every neurosurgeon performs oncology cases and 60% of Kenyan neurosurgeons carry a major tumor case load, in contrast to countries where elective spine surgery predominates neurosurgical practice. Clinical trial enrolment remains uncharted in Kenyan neurosurgery and more than 2/3 of Kenyan counties lack NOS. This survey highlights progress in availability of neurosurgical oncology services while identifying that containing treatment cost, reducing referral delays, and embedding clinical research in clinical practice through mentorship can be NOS growth catalysts.

Pain as a Guide in Glasgow Coma Scale Status for Neurological Assessment.

Neurological status is essential and often challenging for neurosurgical residents and also for neurosurgeons to determine surgical management. Pain as a component of the Glasgow Coma Scale (GCS) can be used as a tool in patients, especially an unconscious or comatose patient. In order to elicit this adequate noxious stimulus, a certain amount of pressure-pain threshold is required upon performing either as the central or peripheral technique. The scientific explanation behind each technique is required and needs to be well understood to aid the localisation of the defect in the neurological system. This paper will briefly review the aid of pain as a neurological guide in GCS status assessment.

3D color multimodality fusion imaging as an augmented reality educational and surgical planning tool for extracerebral tumors.

Extracerebral tumors often occur on the surface of the brain or at the skull base. It is important to identify the peritumoral sulci, gyri, and nerve fibers. Preoperative visualization of three-dimensional (3D) multimodal fusion imaging (MFI) is crucial for surgery. However, the traditional 3D-MFI brain models are homochromatic and do not allow easy identification of anatomical functional areas. In this study, 33 patients with extracerebral tumors without peritumoral edema were retrospectively recruited. They underwent 3D T1-weighted MRI, diffusion tensor imaging (DTI), and CT angiography (CTA) sequence scans. 3DSlicer, Freesurfer, and BrainSuite were used to explore 3D-color-MFI and preoperative planning. To determine the effectiveness of 3D-color-MFI as an augmented reality (AR) teaching tool for neurosurgeons and as a patient education and communication tool, questionnaires were administered to 15 neurosurgery residents and all patients, respectively. For neurosurgical residents, 3D-color-MFI provided a better understanding of surgical anatomy and more efficient techniques for removing extracerebral tumors than traditional 3D-MFI (P < 0.001). For patients, the use of 3D-color MFI can significantly improve their understanding of the surgical approach and risks (P < 0.005). 3D-color-MFI is a promising AR tool for extracerebral tumors and is more useful for learning surgical anatomy, developing surgical strategies, and improving communication with patients.

A cost analysis of medical students applying to neurological surgery residency: An analysis of the Texas STAR database

IntroductionMedical Students applying to neurosurgery residency programs incur substantial costs associated with interviews, away rotations, and application fees. However, few studies have compared expenses prior to and during the COVID-19 pandemic. This study evaluates the financial impact of COVID-19 on the neurosurgery residency application and identifies strategies that may alleviate the financial burden of prospective neurosurgery residents. MethodsThe TEXAS STAR database was surveyed for applicants of neurosurgical residency programs during the COVID-19 pandemic (2021) and post-pandemic (2022). 66 applicants for the 2021 application cycle and 50 applicants for the 2022 application cycle completed the survey. We compared application fees, away rotations cost, interview cost, and total expenses as reported by the neurosurgery applicants of the 2021 and 2022 application cycle. A Shapiro-Wilk test was used to test for data normality, and a Mann-Whitney U-Test was used to compare costs during the 2021 and 2022 neurosurgery application cycle. ResultsThere was a statistically significant reduction in total expenses in 2021 vs 2022 ($3,934 vs $9,860). Interview and away rotation expenses decreased in 2021 vs 2022 (interview expenses $786 vs $4511, away rotation $1,083 vs $3,000, p < 0.001). Application fee expenses were not different between 2021 and 2022. The greatest reduction in application cost ($11,908) was seen in the South for 2021. ConclusionsThe COVID-19 pandemic significantly reduced total fees associated with the neurosurgical residency application. Virtual platforms in place of in-person interviews could lessen the financial burden on applicants and alleviate socioeconomic barriers in the neurosurgical application process after COVID-19.

Promoting diversity in neurosurgery through a virtual symposium.

The rates of women and underrepresented racial and ethnic minority (UREM) students successfully matching into neurosurgical residency are extremely low and do not reflect the makeup of the general population. As of 2019, only 17.5% of neurosurgical residents in the United States were women, 4.95% were Black or African American, and 7.2% were Hispanic or Latinx. Earlier recruitment of UREM students will help to diversify the neurosurgical workforce. Therefore, the authors developed a virtual educational event for undergraduate students entitled "Future Leaders in Neurosurgery Symposium for Underrepresented Students'' (FLNSUS). The primary objectives of the FLNSUS were to expose attendees to 1) neurosurgeons from diverse gender, racial, and ethnic backgrounds; 2) neurosurgical research; 3) opportunities for neurosurgical mentorship; and 4) information about life as a neurosurgeon. The authors hypothesized that the FLNSUS would increase student self-confidence, provide exposure to the specialty, and reduce perceived barriers to a neurosurgical career. To measure the change in participant perceptions of neurosurgery, pre- and postsymposium surveys were administered to attendees. Of the 269 participants who completed the presymposium survey, 250 participated in the virtual event and 124 completed the postsymposium survey. Paired pre- and postsurvey responses were used for analysis, yielding a response rate of 46%. To assess the impact of participant perceptions of neurosurgery as a field, pre- and postsurvey responses to questions were compared. The change in response was analyzed, and a nonparametric sign test was performed to check for significant differences. According to the sign test, applicants showed increased familiarity with the field (p < 0.001), increased confidence in their abilities to become neurosurgeons (p = 0.014), and increased exposure to neurosurgeons from diverse gender, racial, and ethnic backgrounds (p < 0.001 for all categories). These results reflect a significant improvement in student perceptions of neurosurgery and suggest that symposiums like the FLNSUS may promote further diversification of the field. The authors anticipate that events promoting diversity in neurosurgery will lead to a more equitable workforce that will ultimately translate to enhanced research productivity, cultural humility, and patient-centered care in neurosurgery.

Cross-Sectional Analysis of Neurosurgical Residency Websites During the Virtual Interview Cycle

The loss of in-person interviews during the COVID-19 pandemic warrants an investigation into what information is provided to applicants through neurosurgery residency program websites (NRPWs). This study examines NRPWs across the United States and Canada to determine what details are provided to applicants through their respective websites. Accreditation Council for Graduate Medical Education accredited neurologic surgery residency programs were identified through the American Association of Neurological Surgeons (AANS) website. NRPWs were searched for 48 criteria, including program overview, application requirements, and curriculum information. Small programs were defined as 1-2 residents per class, while large programs were classified as those with 3-4 residents per year. Content differences were analyzed between the top 20 and remaining programs per the Doximity Residency Navigator Rankings. The most prevalent information among 122 NRPWs was the neurosurgery residency overview (95%), names of faculty members (95%), and names of current residents (94%). Top-20 NRPWs were more likely to include post PGY-7 fellowships (90% vs. 61% P= 0.0108), operating room virtual reality experience (35% vs. 12% P= 0.0160), and faculty research (90% vs. 62% P= 0.0182) than the remainder of the programs. This study investigates NRPW content after the COVID-19 pandemic. We report broad variability in content provided by various neurosurgical training programs. Higher-ranked neurosurgery programs are more likely to include fellowship information, operating room virtual reality experience, and faculty research than lower-ranked programs.

Comparing the influence of mixed reality, a 3D viewer, and MRI on the spatial understanding of brain tumours

Background: Multiple 3D visualization techniques are available that obviates the need for the surgeon to mentally transform the 2D planes from MRI to the 3D anatomy of the patient. We assessed the spatial understanding of a brain tumour when visualized with MRI, 3D models on a monitor or 3D models in mixed reality.Methods: Medical students, neurosurgical residents and neurosurgeons were divided into three groups based on the imaging modality used for preparation: MRI, 3D viewer and mixed reality. After preparation, the participants needed to position, scale, and rotate a virtual tumour inside a virtual head of the patient in the same orientation as the original tumour would be. Primary outcome was the amount of overlap between the placed tumour and the original tumour to evaluate accuracy. Secondary outcomes were the position, volume and rotation deviation compared to the original tumour.Results: A total of 12 medical students, 12 neurosurgical residents, and 12 neurosurgeons were included. For medical students, the mean amount of overlap for the MRI, 3D viewer and mixed reality group was 0.26 (0.22), 0.38 (0.20) and 0.48 (0.20) respectively. For residents 0.45 (0.23), 0.45 (0.19) and 0.68 (0.11) and for neurosurgeons 0.39 (0.20), 0.50 (0.27) and 0.67 (0.14). The amount of overlap for mixed reality was significantly higher on all expertise levels compared to MRI and on resident and neurosurgeon level also compared to the 3D viewer. Furthermore, mixed reality showed the lowest deviations in position, volume and rotation on all expertise levels.Conclusion: Mixed reality enhances the spatial understanding of brain tumours compared to MRI and 3D models on a monitor. The preoperative use of mixed reality may therefore support the surgeon to improve spatial 3D related surgical tasks such as patient positioning and planning surgical trajectories.
