Neurosurgery Residency Programs Research Articles

Analysis of neurosurgery resident research activity in the United States.

Evaluation of the demographic and academic characteristics of current neurosurgery residents may provide prospective students with insight into factors that affect research output. Therefore, this study aimed to evaluate the research output among neurosurgery residents. US neurosurgery residency programs were abstracted from the American Association of Neurological Surgeons website. Demographic data on 1690 current residents across 119 programs were collected using publicly available institutional websites, Doximity, and LinkedIn. The h-index of each resident was recorded using Scopus and exported into the NIH iCite tool to determine the weighted relative citation ratio (w-RCR) and mean relative citation ratio (m-RCR). The total number of publications, h-index, and w-RCR were used as a proxy for research output, while m-RCR was used to measure research impact. One-way ANOVA and Kruskal-Wallis H-tests were used to assess the statistical significance of relationships between demographic data and measures of research activity. A total of 1690 residents (25.4% female), representing 119 programs, were evaluated. Neurosurgery residents had an average of 17 publications, h-index of 5.5, m-RCR of 1.4, and w-RCR of 16.9, with an upward trend of research activity by postgraduate year (PGY) class. Male residents on average had a greater total number of publications (p < 0.001), higher h-index (p < 0.001), and higher w-RCR (p = 0.002) compared with their female peers. Significant differences in research activity were also observed by degree (Doctor of Medicine [MD], Doctor of Osteopathy [DO], or other), where those with MD and other degrees had higher metrics than those with DO degrees. International medical graduates (IMGs) also had higher research output than American medical graduates (AMGs) (p < 0.001). Differences in all measures of research activity except impact were also observed in research activity when pre-residency medical school ranks were compared. The authors observed overall high research activity among neurosurgery residents. Factors such as gender, degree, PGY, IMG/AMG status, and medical school rank may therefore be related to the success of matching within neurological surgery. Although large disparities in gender representation have been identified in neurosurgery, newer classes are trending toward shrinking the gap. These data may be used by prospective residents to gauge changes and progress occurring in the neurosurgery match.

Introducing a novel hybrid educational boot camp to augment medical student training in neurosurgery.

Neurosurgery subinternships are a critical portion of the medical student application to neurosurgery residency programs, allowing programs to assess the student's clinical knowledge, interpersonal skills, work ethic, and character. Despite how critical these auditions are, many students have a poor understanding of expectations prior to beginning these subinternships. Thomas Jefferson University hosted a combined in-person and virtual boot camp session open to all medical students interested in neurosurgery. The authors sought to determine the effectiveness of this inaugural course. A total of 304 registered participants were sent a survey assessing their attitudes toward neurosurgery subinternships, beliefs about their abilities, and their comfort with various neurosurgical skills. All participants were sent a postsession survey composed of the same questions. The mean scores for responses to pre- and postsession survey questions were recorded based on graduating year and by medical school type (US allopathic [US MD], US osteopathic [US DO], or foreign degree/international medical graduate [IMG]). Differences in means between pre- and postsession survey responses were analyzed using the Student t-test, and statistical significance was set at p < 0.05. A total of 112 presession surveys and 64 postsession surveys were completed, yielding a presession survey response rate of 36.8% and a postsession survey response rate of 21.1%. Seventy-five percent of the postsession survey respondents attended virtually, and 25% were in-person. US MD, US DO, and IMG attendees demonstrated a significantly increased understanding of the expectations of a neurosurgery subintern (p < 0.001). All students had significantly increased confidence in their ability to succeed as subinterns (US MD students and IMGs p < 0.001, US DO students p < 0.05). Regarding procedural confidence, US MD students had increased confidence in craniotomies and cranial plating (p < 0.001). When comparing responses by graduation year, students in the classes of 2024 and 2025 (rising 4th-year and rising 3rd-year medical students, respectively) demonstrated significantly increased understanding of expectations and confidence in their ability to succeed (< 0.001). Seventy-five percent of our postsession survey respondents attended virtually, and 25% were in-person. The in-person cohort had greater improvements in comfort with procedures such as craniotomies, cranial plating, and extraventricular drain placement (in-person vs Zoom mean differences: craniotomies and cranial plating, -2.29, extraventricular drain placement, -2.31) (p < 0.05). The boot camp successfully delineated the expectations of neurosurgery subinterns and enhanced the attendees' confidence in their abilities. The authors concluded that a hybrid virtual and in-person format is beneficial and feasible in increasing accessibility to information about neurosurgery subinternships.

Availability and utilization of molecular testing for primary central nervous system tumors among US hospitals.

Advanced molecular testing has increasingly become an integral component for accurate diagnosis of central nervous system (CNS) tumors. We sought to establish the current state of molecular testing availability and approaches for the diagnosis of CNS tumors in US hospitals that conduct high volumes of CNS tumor resections. We distributed a 16-item survey inquiring about molecular testing approaches for CNS tumors to 115 neuropathologists at US hospitals with neurosurgery residency programs. Thirty-five neuropathologists (30.4%) responded to the survey, all of whom indicated their institutions perform molecular testing on CNS tumor tissue. The most commonly offered tests were MGMT methylation profiling and next-generation sequencing. Fourteen respondents (40%) indicated that their institution is able to test for and report all of the molecular alterations included in our survey. Nine (25.7%) respondents indicated that molecular testing is performed as standard of care for all patients with resected CNS tumors. Our results suggest that even in academic hospitals with a high volume of CNS tumor resections, molecular testing for these tumors is limited. Continued initiatives are necessary to expand the availability of molecular testing for CNS tumors to ensure diagnostic accuracy and guide targeted therapy.

Industry payments to academic neurosurgeons in 2021: an open payments cross-sectional analysis

OBJECTIVE The Open Payments Program (OPP) was a database started in 2013 by the US government to report payments made by the medical device and pharmaceutical industry to physicians. Neurosurgery is a technologically advanced field that relies heavily on the latest innovations for complex treatment of its patient population. This study sought to explore the financial relationship between academic neurosurgeons and the industry. METHODS OPP data were reviewed for the year 2021 of all faculty neurosurgeons affiliated with a neurosurgery residency program. Trends related to general payments, research payments, associated research funding, ownership and investment interest, name of the companies making payments, monetary amount of payments per company, and number of payments per company were analyzed. RESULTS Industry payments to 1151 US academic neurosurgeons were reviewed. These neurosurgeons received $121.4 million in payments. Three hundred thirty-two companies made 18,466 payments. The average payment per neurosurgeon was approximately six-fold higher than that of all other physicians. Vascular and spine subspecialties received the highest payments. A higher proportion of research money was allocated to the Pacific division, while all other categories (including total amount) were higher in the Eastern US. Most financial contributions were made by a small number of companies. CONCLUSIONS Neurosurgery has been rated by many as a field fueled by research, innovation, and technology. In 2021, academic neurosurgeons had a strong relationship with the medical device and pharmaceutical industry as reflected in the OPP data. While the true impact on patient care cannot be directly measured, the advancement of the field relies heavily on these collaborations.

334 Resident Salary Compared to Living Wages at US Training Institutions

INTRODUCTION: Resident physician salaries vary by region, though it is unknown how these variations compare to differences in living wages across the United States or what factors drive residency salary discrepancies. METHODS: Publicly available resident salary information was obtained from full-service training centers containing a neurosurgical residency program via institution-specific websites in February 2023 with information on post-graduate year (PGY)-1 through PGY-7 resident compensation for 2022-2023. Living wage calculations by city were generated via the Massachusetts Institute of Technology (MIT) Living-Wage Calculator. Resident salary to living-wage ratios were calculated using PGY-4 salary for each family composition living-wage. Univariate and multivariable analysis of PGY-4 resident salary on affordability was performed, accounting for proportion of expected living wages to taxes, transportation, housing, medical costs, childcare, and food as well as unionization and state income-tax status. RESULTS: 118 neurosurgery residency programs were included, 21 (17.9%) of which were unionized. Residents without children earned a salary greater than living-wage during all years, while single-parent families were unable to earn a living-wage until PGY-7. Residents with 1 child in in 2-adult (single-income) and 2-adult (double-income) families were unable to earn a living-wage until PGY-5 and PGY-3 respectively. Residents with more than 1 child failed to earn a living-wage. Multivariate regression analysis using PGY-4 salary:living-wage ratios in single-child, 2-parent homes showed food expenses and unionization status were always significant. On multivariate regression, unionization was significantly associated with lower living-wage ratios pre-stipend, improved post-stipend, and was again significantly lower after factoring in union dues. CONCLUSIONS: Current resident salaries often preclude a resident from earning a living-wage, especially among junior residents and those with children. Unionization is significantly associated with lower resident income to living-wage ratios.

Sanford Larson, MD, PhD: a pioneering neurosurgeon, scientist, and educator.

Dr. Sanford Larson, MD, PhD (1929-2012), was an influential figure in spinal neurosurgery. Dr. Larson played a pivotal role in establishing neurosurgery's foothold in spinal surgery by serving as the inaugural chair of the Joint Section on Disorders of the Spine and Peripheral Nerves and as a president of the Cervical Spine Research Society. He made many advances in spine care, most notably the modification and popularization of the lateral extracavitary approach to the thoracolumbar spine. Dr. Larson established the neurosurgery residency program at the Medical College of Wisconsin; he also instituted the program's spine fellowship, the first in the United States for neurological surgeons. His mentorship produced numerous leaders in organized neurosurgery and neurosurgical education, including Edward Benzel, MD, Dennis Maiman, MD, PhD, Joseph Cheng, MD, Shekar Kurpad, MD, PhD, and Christopher Wolfla, MD. Dr. Larson was a prominent leader in spinal neurosurgery and his legacy carries on today through his contributions to research, education, and surgical technique.

Gender parity in neurosurgery residencies: an analysis.

The number of women graduating from United States medical schools has reached parity with that of men. However, persistent inequalities and barriers have slowed the pace toward equity in application and representation in neurosurgery residency despite initiatives to increase female representation. The objective of the present study was to assess the advancement of gender parity within neurosurgery residency programs. Additionally, the study aimed to analyze the pipeline dynamics by investigating the effects of attrition on women in neurosurgery, as well as exploring the patterns of female applications to neurosurgery residency programs versus other surgical specialties. Data on the number of active female neurosurgery residents and female applicants to neurosurgery were collected from the Accreditation Council for Graduate Medical Education Data Resource Book from 2007 to 2021 and Electronic Residency Application Service from 2014 to 2022. Linear regression analysis was used to predict the percent of active female residents based on academic year (AY). A Pearson chi-square test was used to determine the odds of a female applying to neurosurgery. The percent of active female residents in neurosurgery increased from 11.0% in 2007 to 21.8% in 2021. Bivariate linear regression analysis using AY as a predictor of the percent of active females showed a statistically significant correlation. On average, the percent of active female residents increased by 0.65% per year. If trends persist, parity for females in neurosurgery will not be reached until 2069. Linear regression analysis of the overall rate of attrition in neurosurgery as a predictor of the percent of active female residents revealed that for every 1% increase in the rate of attrition, the percent of active female residents decreased by 2.91% (p = 0.001). The percent of female applicants to neurosurgery increased from 19.6% in 2014 to 29.8% in 2022 (p = 0.009), yet the odds of a female applying to neurosurgery remain low. Neurosurgery continues to struggle with the recruitment of female medical students even as parity has been reached for female medical school matriculants. Greater effort is needed to recruit and retain female applicants to neurosurgery, including increased transparency in match and attrition metrics.

Factors impacting neurosurgery residents' operative case volume: a nationwide survey.

Neurological surgery residency remains one of the most competitive and longest specialties in terms of training in medicine. The Accreditation Council for Graduate Medical Education uses residents' case volume throughout residency as one of its measures for the quality of surgical training. The objective was to study the variability of residency case volume among US training programs and to analyze the factors that potentially influence that case volume. In line with the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) guidelines, an online survey regarding department size, case volume, number of residents per year, number of dedicated research years, presence of fellows, and resident case volume by the time of graduation was created using Google Forms and distributed to all neurosurgery residency program directors and coordinators in the US. A total of 97 of the 115 programs (84.3%) responded to the survey. Fifteen programs were excluded due to missing data or incomplete resident cohort at the time of the survey, and a total of 82 programs were included in the analysis. The average number of cases performed by residents as lead or senior surgeons by the time of graduation ranged from 900 to 2250 (median 1600 cases). The resident case volume did not have a significant correlation with the program case volume, number of operating attending neurosurgeons, number of residents, number of research years, or presence of fellows. The only factor that impacted the resident case volume was the number of cases performed per faculty. The number of cases performed by residents throughout residency varied significantly between programs. Although other factors play important roles in the quality of training, including autonomy, variation, and complexity of cases, the resident case volume is one of the only measurable factors. This study sheds some light on the factors that potentially influence neurosurgical resident case volume.

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

OBJECTIVE 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Exploring the Validity and Reliability of Neurosurgery Residency Program Rankings: A Quantitative Analysis

To evaluate the relationships between Doximity rankings (Doximity, Inc.) of residency programs and 2 new ranking systems based on publication rates and academic pursuits. We collected data on 550 neurosurgery graduates over 3years. We analyzed the median number of published manuscripts per resident and the percentage of residents pursuing academic careers and compared them across the Doximity Research Productivity and Reputation Rankings. We used logistic regression to evaluate the relationships among the rankings, publication rates, and academic pursuits. Neurosurgery residents published a median of 10 manuscripts per person (IQR: 6-17), and 50% (IQR: 33%-67%) of residents in a given program pursued an academic career. The distributions of the median number of published manuscripts across the Doximity Research Productivity Ranking and the Doximity Reputation Ranking tiers differed significantly (all P<0.001). Similarly, the distribution of the percentage of residents pursuing an academic career across both published Doximity ranking systems' tiers differed significantly (all P=0.02). Moreover, we found moderate agreement between the 2 Doximity rankings, fair agreement between the publication and the other 3 rankings, and slight agreement between the academic pursuit and the Doximity rankings. We introduced 2 new methods to rank residency programs based on the number of graduates pursuing an academic position and the median number of published manuscripts per resident. By taking a comprehensive approach, neurosurgery applicants can ensure that they select a residency program that meets their needs and offers them the best opportunity for success.

Gender diversity in neurosurgical training: an analysis of trends and resident program characteristics

OBJECTIVE Recent trends have shown more women entering neurosurgery, but large gender gaps in the number of female trainees continue to persist. A previous study on the gender diversity of residents and faculty in neurosurgery training programs found that only 18.2% of residents and 8.7% of faculty at neurosurgical training programs were female. The goal of this study was to better understand program characteristics that may affect the recruitment of female residents and the gender composition of neurosurgery residency programs. METHODS The authors assessed publicly available information on websites and social media from 116 Accreditation Council for Graduate Medical Education (ACGME)–accredited neurosurgery residency programs from the 2022–2023 academic year. Data collected on residents included gender and postgraduate year (PGY), geographic region, accreditation year, and complement size for programs. The authors analyzed the distribution of female residents at each program and compared accreditation year, program size, program geographics, PGY, and acceptance rates. RESULTS There were 1602 residents across the 116 programs included in this study: 1223 (76.3%) male and 379 (23.7%) female residents. The gender distribution of female residents showed 29 programs had 30% or more female residents, 50 programs had between 16% and 30%, and 37 had fewer than 16%, including 8 with none. There were significantly more PGY-1 than PGY-7 female residents (28.9% vs 16.4%, p &lt; 0.01). Programs with ACGME accreditation before 1970 had significantly higher percentages of female residents (26.0%) compared with those accredited after 1970 (18.2%, p &lt; 0.01). Program size was associated with a higher percentage of female residents (large = 25.2%, medium = 24.9%, and small = 19.6%), although the results were not significant. The distribution of female trainees across five geographic regions of the United States was fairly even: Northeast (24.5%), West (25.2%), South Atlantic (23.1%), South Central (21.8%), and North Central (21.2%). Residency acceptance rates were similar between genders. CONCLUSIONS The underrepresentation of women in neurosurgery residency programs remains a significant issue. While some programs have achieved higher female representation than the overall average proportion of female neurosurgery residents, many still fall short. There are twice as many female PGY-1 compared with PGY-7 residents, suggesting increased recruitment over the past few years. Programs with longer accreditation histories have significantly higher proportions of female residents. Larger program size can also play a role in attracting more female residents, but geographic location did not impact gender composition of resident cohorts in this study.

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.

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.

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.

Competitive neurosurgery residency programs: Predictors of matching outcome and research productivity

ObjectiveThe aim of this study was to provide a comprehensive assessment of preresidency research and school as predictors of competitive neurosurgery matching and to assess for any correlations between preresidency and intraresidency research productivity. MethodsIndividuals who graduated from US neurosurgery programs from 2018 through 2020 were assessed for medical school, degree (MD, DO, or PhD), preresidency versus intraresidency publications, author order, article type, and neurosurgery matching outcomes. ResultsMedical school ranking (top 50) and the number of published papers (≥3) before intern year were predictors for matching to a top-25 residency program after adjusting for other covariates (p < 0.001, p = 0.002, respectively). On average, individuals who published more papers before residency published more papers during residency. For the comprehensive clinical papers category, there was a significant difference between individuals from the top 25 residency programs and others, with a stronger correlation between the number of preresidency publications and intraresidency publications for neurosurgeons who attended a top-25 residency program (r = 0.378 and r = 0.179, respectively; p = 0.02). ConclusionMedical school ranking and research productivity as measured by the number of published papers were independently associated with matching to the top 25 residency programs. In addition, high research productivity in the preresidency years was associated with continued productivity during residency, especially in the category of comprehensive clinical papers.

Analysis of Current Neurological Surgery Residents and Prior Medical Education: Do Medical School Attributes Matter?

With the recent changes to the U.S. Medical Licensing Examination grading system, an understanding of the factors that influence the neurological surgery residency match process is crucial for residency directors. The aim of the present retrospective study was to explore the associations of medical school location, ranking, private school status, size, and presence of an American Association of Neurological Surgeons (AANS) chapter or neurological surgery interest group (NSIG) with the neurosurgery match outcomes. An enrollment list of all accredited U.S. neurosurgery residency programs was compiled on June 28, 2021. For the included residents, the residency program, degree, and previously attended medical school were retrieved. The geographic location, ranking, private school status, and size were collected for the residency programs and medical schools attended by the residents at each program. A total of 1437 residents from 101 neurosurgery residency programs (89%) were included. Graduates from the top 25 medical schools were more likely to match into their home residency programs (P < 0.001) and highly ranked residency programs (P < 0.001). Students from larger medical schools were also more likely to match into larger (P < 0.001) and highly ranked (P < 0.001) programs than were applicants from smaller schools. Students from medical schools with an AANS chapter or NSIG were also more likely to match into top ranked programs (P < 0.001 for both). Medical students from the top 25 medical schools, private medical schools, medical schools with an AANS chapter, and medical schools with an NSIG were more likely to match into a prestigious residency program. These findings suggest that underlying biases might be present for program directors to consider in the resident selection process.

423 Trends in Utilization of Standardized Letters of Recommendation in the 2021-2022 Neurosurgery Application Process

INTRODUCTION: Standardized LORs (SLORs) were introduced during the 2020-2021 neurosurgery residency application cycle, but suffered from poor inter-rater reliability and significant grade inflation. Changes were made to the SLOR template and utilization patterns in response to these shortcomings. METHODS: This cross-sectional study analyzed all SLORs submitted to a single neurosurgery residency program over the 2021-2022 cycle. Data from seven competency domains and the overall rating were recorded and stratified by academic category of letter writer. Inter-rater reliability was evaluated using Krippendorff’s Alpha. Frequency of letters written was evaluated using Kruskal-Wallis H Test. RESULTS: 90% of SLORs rated applicants among the Top 25%, but there was a significant decrease in the usage of the “Top 1%” and “Top 2-5%” ratings from the prior application cycle. Inter-rater reliability was poor across all competencies. Writers who completed one SLOR rated applicants higher and had a narrower range than those who completed multiple SLORs. CONCLUSIONS: Changes in the format and subsequent utilization patterns of SLORs have slightly decreased grade inflation; however, inter-rater reliability remains poor. The most wide-ranging evaluators submitted the highest number of SLORs, suggesting that future evaluation and usage of SLORs should emphasize letter-writer characteristics and numbers of SLORs written. Overall, SLORs have been well and broadly accepted with subtle improvements in the second year of utilization.

417 An Athlete-Oriented Holistic Coaching Program Targeting Performance and Wellbeing in Neurosurgery Residents

INTRODUCTION: Neurosurgery residency is a demanding environment, requiring high levels of performance endured over long periods of time. As a result, neurosurgery residency has been associated with significant rates of fatigue, depression, and physician burnout. To address this, the authors instituted a program within the residency, entitled the “Performance Protection Program,” consisting of a personalized program based on principles used with world-class extreme sports athletes designed for residents to achieve sustainably high levels of performance. METHODS: A 12-month coaching program was instituted by a performance coach within a single neurosurgery residency program. Residents attended individual and team-based monthly meetings, engaged in offsite team outings, and completed interactive reflective questions. The program focused on several pillars of performance excellence including mental, emotional, social, physical and physiological domains. RESULTS: Residents engaged in a total of 19 team sessions, 3 team outings, and over 87 individual sessions by mobile device or in-person during which they strategized with the coach on topics including: productivity, communication, regulating emotions under pressure, in-hospital nutrition, meal preparation, efficiency, accountability, posture and strength, job interviewing, confidence, visualization skills, and team leadership dynamics. By demand, a bi-weekly posture and mobility session was incorporated into the program. Early feedback demonstrated a need for adaptive strategies personalized to the resident’s stage of training and life. Most residents expressed need for improvement in nutrition, physical wellness, and communication under fatigue. CONCLUSIONS: Neurosurgery residency is stress-provoking and arduous for trainees. To optimize resident performance while minimizing burnout, a curriculum based on principles in extreme sports was successfully enacted over a 12-month period. Other training programs may utilize similar interventions to promote resident well-being and improve mental and physiological states.

Realistic Assessment of Research Publications by Neurosurgery Residency Applicants.

Neurosurgical residency applicants' prior research experience can amplify their ability to stand out to prospective neurosurgery programs. We attempted to accurately quantify the number of research publications coauthored by applicants by analyzing the publications of applicants who matched into neurosurgery in the 2021 Match. Scopus, a peer-reviewed literature database, was queried for publications by applicants who matched into neurosurgery in the 2021 Match before the finalization of rank lists. Conference papers, abstracts, and book chapters were excluded to determine an accurate average of actual publications. Descriptive statistics for resident publication data were used, with a Mann-Whitney U test used to compare research productivity between male and female residents. There were 234 positions filled by the 2021 Match, and 233 neurosurgical residents were identifiable in this study. A total of 187 residents matching from U.S. Doctor of Medicine and Doctor of Osteopathic Medicine programs were identified with 946 total publications-an average of 5.1 publications per resident. Analysis of descriptive statistics revealed type of research conducted, authorship information, most published journals, and citation data. Significant differences were found in the number of publications between male and female applicants with averages of 5.6 and 3.8 publications, respectively. Students matriculating to neurosurgery residency programs display a wide range of research productivity. Typical U.S. Doctor of Medicine and Doctor of Osteopathic Medicine applicants have coauthored a mean of 5.1 and a median of 4.0 publications. This information may assist program directors in weighing applicants' research background and give medical students interested in the field reasonable research expectations.

744 Reducing Implicit Bias in the Neurosurgery Application and Interview Process

INTRODUCTION: Each year, Neurosurgery residency programs aim to match the best and brightest applicants aspiring to join the field. Traditionally, metrics such as USMLE Step 1 and 2 scores, publications, and medical school grades have played a key role in determining who is interviewed, the interviewers’ impression of the candidates, and subsequently who is most likely to match. However, these evaluative tools are known to reflect biases in the medical and medical education systems, potentially overlooking diverse applicants well-suited for a career in neurosurgery. METHODS: During the 2020-2021 and 2021-2022 residency application cycles, our program instituted a new process for reviewing applications, conducting interviews, and generating a final rank list. Each application was reviewed by attending and resident reviewers, who were blinded to potentially biasing information including pictures and board scores. From this review, selected applicants were interviewed using a set of standardized questions, designed to evaluate specific domains essential for success in neurosurgery. Linear regression was performed to determine correlation between traditional metrics and domain-based interview scores and final rank. RESULTS: 137 applicants were interviewed. There was no significant correlation between rank and Step 1 (p = 0.47, R2 = 0.003) or Step 2 scores (p = 0.16, R2 = 0.014).Interview scores lacked statistically significant association with Step 1 scores (p=0.10, R2=.02), but were found to correlate with Step 2 scores (p = 0.02, R2 = .05). CONCLUSIONS: In our two-cycle experience using this new system, we found no correlation between applicants’ Step 1 scores and their interview scores or final rank list position. We propose this as one alternative method to historically biased tools for evaluating neurosurgery applicants.
