Case distributions in general surgery residency: Subspecialization occurs before fellowship

Decreasing Resident Vascular Case Volumes Have Not Changed National Numbers of Vascular Fellowship Applications in US General Surgery Residents Over the Past Twenty Years

OBJECTIVES

With an aging workforce and high prevalence of vascular disease, the US is expected to face a pronounced shortage of vascular surgeons over the next 2 decades. This has driven initiatives to expand vascular surgery training positions leading to the rise of integrated residency programs (0 + 5) and the expansion of traditional fellowships (VSFs, 5 + 2). Given the increase in dedicated vascular surgery training positions, there has been a growing concern that general surgery residents (GSRs) are experiencing decreased vascular case volumes. We aim to evaluate trends in vascular surgery specialty choice relative to vascular case volumes for US GSRs over the last 20 years.

DESIGN

Using the Accreditation Council for Graduate Medical Education (ACGME) Case Log Graduate Statistics National Report, a retrospective analysis of ACGME-accredited GSR vascular case volumes was performed from academic year 1999-2000 to 2021-2022. Fellowship data was retrospectively reviewed using the available National Resident Matching Program (NRMP) Fellowship Match Data & Reports for 2004-2023.

RESULTS

Graduating GSRs logged increasing numbers of major cases between AY 1999-2000 and AY 2021-2022 (p < 0.001) with 2022 graduates logging on average 98 more cases per resident compared to 2000 graduates. Mean total vascular cases decreased (p = 0.005) with 2022 graduates logging approximately 78 fewer vascular cases on average compared to the 2000 graduates, a 40% decrease in vascular case volume. Despite the decrease, US GSRs have applied to VSF at a relatively consistent rate: 8.5% in 2001-2002, 8% in 2011-2012, and 6% in 2021-2022. 2023 demonstrated an increase to 8.3%.

CONCLUSION

Over the past 2 decades, GSRs have experienced a substantial decrease in exposure to vascular surgery cases during their training; however, residents continue to apply for VSF at a relatively constant rate suggesting that interest in the specialty may be related to factors other than exposure to vascular cases.

Defining the Disparity: A Multi-Institutional Analysis of Factors Associated With Decreased Resident Operative Experience

INTRODUCTION

Technical learning in surgical training is multifaceted and existing literature suggests a positive relationship between case volume and proficiency. Little is known about factors associated with a decreased volume of operative experience. This study aimed to identify resident and program factors associated with general surgery residents (GSR) in the bottom quartile of logged case volume upon program completion.

METHODS

A post hoc analysis of a multicenter study was used to examine case logs for categorical GSR. Participants included graduates between 2010 and 2020 from 20 programs. Residents below and above the 25th percentile for total operative volume were compared.

RESULTS

The present study includes 1343 GSR who graduated over the 11-y period. In total, 336 residents were below the 25th percentile and 1007 residents were above the 25th percentile. Those below the 25th percentile were more likely to be female (41% versus 34%, P = 0.02), identify as underrepresented in medicine (22% versus 14%, P < 0.01), and pursue fellowship (86% versus 80%, P = 0.01) compared to those above the 25th percentile. Residents below the 25th percentile were more likely to have graduated from a low volume program (55% versus 25%, P < 0.01) and from top National Institutes of Health funded institutions (57% versus 52%, P = 0.01).

CONCLUSIONS

This study identified individual and program characteristics associated with lower operative volume of GSR. Understanding such characteristics will aid surgical educators to achieve better equity in training.

General Surgery Trainee Cases Over Time: Postgraduate Year Matters

BACKGROUND

Trainees and attending surgeons alike have concerns about resident and fellow operative volume/breadth, competency, and overall readiness for practice. This is an important topic within surgical graduate medical education. Our goal was to analyze the change in general surgery trainee operative experience over time by postgraduate year.

METHODS

Institutional operative records from two corresponding three-month time periods in 2009 and 2018 at the residency program's main hospital site were reviewed. Cases assisted on by general, vascular, or thoracic surgery trainees were included. The number of cases per level, combination of trainees in each case, and categories of cases were compared over time.

RESULTS

There were 1940 cases in 2009 and 1967 cases in 2018 over the respective time periods. The distribution of trainees was different (P < .001), with a similar number of PGY-1 and fellow cases, a decrease in PGY-2 and PGY-5 cases, and an increase in PGY-3 and PGY-4 cases. The number of cases with two trainees, double scrubbed cases, increased from 19.6% to 26.8% (P < .001). In addition, there were differences in the resident years that double scrubbed cases together, an increase in robotic and endovascular surgery, and a decrease in open cases.

CONCLUSIONS

This analysis of cases shows that resident operative volume over approximately a decade has been largely preserved, with some change in the distribution of cases based on trainee level, an increase in cases with more than one trainee, and a rise of minimally invasive surgery with a corresponding decrease in open cases.

Disparities in the Operative Experience Between Female and Male General Surgery Residents: A Multi-institutional Study From the US ROPE Consortium

OBJECTIVE

To examine differences in resident operative experience between male and female general surgery residents.

BACKGROUND

Despite increasing female representation in surgery, sex and gender disparities in residency experience continue to exist. The operative volume of male and female general surgery residents has not been compared on a multi-institutional level.

METHODS

Demographic characteristics and case logs were obtained for categorical general surgery graduates between 2010 and 2020 from the US Resident OPerative Experience Consortium database. Univariable, multivariable, and linear regression analyses were performed to compare differences in operative experience between male and female residents.

RESULTS

There were 1343 graduates from 20 Accreditation Council for Graduate Medical Education-accredited programs, and 476 (35%) were females. There were no differences in age, race/ethnicity, or proportion pursuing fellowship between groups. Female graduates were less likely to be high-volume residents (27% vs 36%, P < 0.01). On univariable analysis, female graduates performed fewer total cases than male graduates (1140 vs 1177, P < 0.01), largely due to a diminished surgeon junior experience (829 vs 863, P < 0.01). On adjusted multivariable analysis, female sex was negatively associated with being a high-volume resident (OR = 0.74, 95% CI: 0.56 to 0.98, P = 0.03). Over the 11-year study period, the annual total number of cases increased significantly for both groups, but female graduates (+16 cases/year) outpaced male graduates (+13 cases/year, P = 0.02).

CONCLUSIONS

Female general surgery graduates performed significantly fewer cases than male graduates. Reassuringly, this gap in operative experience may be narrowing. Further interventions are warranted to promote equitable training opportunities that support and engage female residents.

Trends in pancreatic surgery experience in general surgery residency in the US, 1990–2021

BACKGROUND

We hypothesized a decline in resident pancreatic operative experience. The study assesses trends in that experience since 1990.

METHODS

Accreditation Council for Graduate Medical Education (ACGME) national case log data of general surgery residency graduates from 1990 to 2021 were reviewed. Collected and analyzed were the mean and median total number of pancreatic operations per resident, the mean number of specific case types performed, and the annual number of residency graduates. For selected procedures, the mean number of cases by resident role (Surgeon-Chief and Surgeon-Junior) was also analyzed.

RESULTS

Both the mean and median total number of resident pancreatic operations has declined since 2009 as have the mean number of several specific pancreatic case types, including resections. The annual number of residency graduates has significantly increased since 1990, and particularly since 2009.

CONCLUSIONS

Resident volume in pancreatic operations has significantly declined over the last decade.

An analysis of vascular surgery education publications reveals an educational shortage

BACKGROUND

As vascular surgery training continues to evolve with the growth of integrated vascular surgery residency (0+5) programs and the consolidation of fellowship programs, optimizing all aspects of the education for vascular surgery trainees, both fellows and 0+5 residents, has become increasingly important. In the present study, we aimed to determine the prevalence, quality, and content of vascular surgery education publications across journals.

METHODS

Journal websites (n = 26) and PubMed were queried to identify vascular surgery education publications from 2012 to 2021. The publications were organized into 11 content categories: (1) curriculum, (2) simulation, (3) trainee assessment, (4) program evaluation, (5) wellness/burnout, (6) diversity/inclusion, (7) mentorship/career, (8) case outcomes, (9) perceptions of training, (10) social media, and (11) other. Publication interactivity and quality were measured via PlumX data and Medical Education Research Study Quality Instrument scores. The data were analyzed via univariate analysis and linear regression.

RESULTS

A total of 115 vascular surgery education publications (0.2% [interquartile range (IQR), 0.04%-0.5%] of total publications) were identified from the selected journals. The Journal of Vascular Surgery had the highest proportion (0.8%) of vascular surgery education publications, followed by the Journal of Surgical Education (0.7%) and Annals of Vascular Surgery (0.6%). Vascular surgery journals constituted most (79%) of the publications. Of the authors, 15% (IQR, 0%-25%) had a master's or doctorate degree in education. Senior authors were more often identified as male gender (77%), and more first authors (41%) were identified as female gender. An interactivity analysis showed that there were 10.3 citations (IQR, 12), 33.1 captures (IQR, 34), and 8.4 social media interactions (IQR 14) per publication. The educational quality had a median Medical Education Research Study Quality Instrument score of 11 (IQR, 9-12.5), with 49% of publications having a score greater than the median. Publications on training (44% curriculum and 20% simulation) were significantly more frequent than other topics (P < .001), with no change in the publication content over 10 years (P = .29). The volume of vascular surgery education publications did not change during the study period (P = .13) despite the ongoing changes in the educational environment.

CONCLUSIONS

Despite the increasing importance placed on vascular surgery education by national vascular societies, publications on vascular surgery education have remained sparse among all journals. Also, the vascular surgery educational content has not changed during the past 10 years, with a primary focus on curriculum and simulation training. Further promotion of vascular surgery educational research is required to increase the quality, volume, and diversity of education publications.

A multi-institutional study from the US ROPE Consortium examining factors associated with directly entering practice upon residency graduation

BACKGROUND

There is concern regarding the competency of today's general surgery graduates as a large proportion defer independent practice in favor of additional fellowship training. Little is known about the graduates who directly enter general surgery practice and if their operative experiences during residency differ from graduates who pursue fellowship.

METHODS

Nineteen Accreditation Council for Graduate Medical Education-accredited general surgery programs from the US Resident OPerative Experience Consortium were included. Demographics, career choice, and case logs from graduates between 2010 to 2020 were analyzed.

RESULTS

There were 1,264 general surgery residents who graduated over the 11-year period. A total of 248 (19.6%) went directly into practice and 1,016 (80.4%) pursued fellowship. Graduates directly entering practice were more likely to be a high-volume resident (43.1% vs 30.5%, P < .01) and graduate from a high-volume program (49.2% vs 33.0%, P < .01). Direct-to-practice graduates performed 53 more cases compared with fellowship-bound graduates (1,203 vs 1,150, P < .01). On multivariable analysis, entering directly into practice was positively associated with total surgeon chief case volume (odds ratio = 1.47, 95% confidence interval 1.18-1.84, P < .01) and graduating from a US medical school (odds ratio = 2.54, 95% confidence interval 1.45-4.44, P < .01) while negatively associated with completing a dedicated research experience (odds ratio = 0.31, 95% confidence interval 0.22-0.45, P < .01).

CONCLUSION

This is the first multi-institutional study exploring resident operative experience and career choice. These data suggest residents who desire immediate practice can tailor their experience with less research time and increased operative volume. These data may be helpful for programs when designing their experience for residents with different career goals.

Trends of core versus subspecialty operative procedures completed in general surgery residency training programs

INTRODUCTION

General surgery residency involves performing subspecialty procedures in addition to the core general procedures. However, the proportion of core general surgery versus subspecialty procedures during training is variable and its temporal changes are unknown. The goal of our study was to assess the current trends in core general surgery and subspecialty procedure distributions during general surgery residency training.

METHODS

Data were collected from the ACGME core general surgery national resident available report case logs from 2007 to 2019. Descriptive and time series analyses were used to compare proportions of average procedures performed per resident in the core general surgery category versus the subspecialty category. F-tests were conducted to show whether the slopes of the trend lines were significantly non-zero.

RESULTS

The mean of total procedures completed for major credit by the average general surgery resident increased from 910.1 (SD=30.31) in 2007 to 1070.5 (SD=37.59) in 2019. Over that same period, the number of general, cardiothoracic, plastic and urology surgery procedures increased by 24.9%, 9.8%, 76.6% and 19.3%, respectively. Conversely, vascular and paediatric surgery procedures decreased by 7.6% and 30.7%, respectively. The neurological surgery procedures remain stable at 1.1 procedures per resident per year. A significant positive correlation in the trend reflecting total (p<0.0001), general (p<0.0001) and plastic (p<0.0016) surgery procedures and the negative correlation in the trend lines for vascular (p<0.0006) and paediatric (p<0.0001) surgery procedures were also noted.

CONCLUSIONS

Trends in overall surgical case volume performed by general surgery residents over the last 12 years have shown a steady increase in operative training opportunity despite the increasing number of subspecialty training programmes and fellowships. Further research to identify areas for improvement and to study the diversity of operative procedures, and their outcomes is warranted in the years to come.

Are Esophagectomy Board Requirements Achievable? A Multi-Institutional Analysis

Duty-hour restrictions have implications on trainee operative exposure necessary to meet minimum case-volume requirements. We utilized a previously validated simulation model to evaluate the effect of program volume, trainee numbers and complement, and rotation schedule on the probability of achieving adequate esophagectomy case numbers for cardiothoracic surgery trainees. A ProModel simulator centered on probabilistic distributions of operative cases was utilized. Historical data from five 2-year cardiothoracic surgery training programs were obtained from 2016-2018 and used as inputs to the simulator that generated 10,000 "trainee 2-year periods" per program. Programs varied in annual average esophagectomy volume (12-91 per year), with 2-4 trainees graduating over a 2-year training period. If esophagectomy cases were distributed solely based on scheduling and institutional volume, only 60% of evaluated programs could adequately expose all trainees in esophagectomy to meet case requirements. The 3 programs with adequate esophagectomy volumes had averaged 3.3 times (range 3.0-3.6) the minimum number of board-required cases for their programs' trainees. The ability of programs to provide trainees with adequate esophagectomy volume is challenging based on institutional volume and scheduling. Through simulation, we demonstrate that programs need >2 times the expected minimum number of esophagectomies to ensure that >90% of trainees meet case-volume requirements. Programs may consider strategies such as allowing trainees to select cases based on personal need, train fewer fellows, or enable trainees to seek subspecialty exposure externally to achieve minimum esophagectomy case-load requirements.

Current Trainee and Workforce Patterns for Thyroid and Parathyroid Surgery in the United States

OBJECTIVE

Thyroid and parathyroid surgery is performed by both general surgeons and otolaryngologists. We describe the proportion of surgeries performed by specialty, providing data to support decisions about when and to whom to direct research, education, and quality improvement interventions.

METHODS

We tabulated case numbers for privately insured patients undergoing thyroid and parathyroid surgery in Marketscan: 2010-2016 and trainee case logs for residents and fellows in general surgery and otolaryngology. Summary statistics and tests for trends and differences were calculated.

RESULTS

Marketscan data captured 114 500 thyroid surgeries. The proportion performed by each specialty was not significantly different. Otolaryngologists performed 58 098 and general surgeons performed 56 402. Otolaryngologists more commonly performed hemithyroidectomy (n = 25 148, 43.29% of all thyroid surgeries performed by otolaryngologists) compared to general surgeons (n = 20 353, 36.09% of all thyroid surgeries performed by general surgeons). Marketscan data captured 21 062 parathyroid surgeries: 6582 (31.25%) were performed by otolaryngologists, and 14 480 (68.75%) were performed by general surgeons. The case numbers of otolaryngology and general surgery trainees completing residency and fellowship varied 6- to 9-fold across different sites. The wide variation may reflect both the level of exposure a particular training program offers and trainee level of interest.

CONCLUSION

Thyroid surgical care is equally provided by general surgeons and otolaryngologists. Both specialties contribute significantly to parathyroid surgical care. Both specialties should provide input into and be targets of research, quality, and education interventions.

Identifying technical skills and clinical procedures in surgery for a simulation-based curriculum: a national general needs assessment

BACKGROUND

The efficacy of simulation-based training in surgical education is well known. However, the development of training programs should start with problem identification and a general needs assessment to ensure that the content is aligned with current surgical trainee needs. The objective of the present study is to identify the technical skills and clinical procedures that should be included in a simulation-based curriculum in general surgery.

METHODS

A national, three-round Delphi process was conducted to achieve consensus on which technical skills and clinical procedures should be included in a simulation-based curriculum in general surgery. In total, 87 key opinion leaders were identified and invited to the study.

RESULTS

Round 1 of the Delphi process had a response rate of 64% (56/87) and a total of 245 suggestions. Based on these suggestions, a consolidated list of 51 technical skills or clinical procedures was made. The response rate in Delphi round 2 was 62% (54/87) resulting in a pre-prioritized order of procedures for round 3. The response rate in Delphi round 3 was 65% (35/54). The final list included 13 technical skills and clinical procedures. Training was predominantly requested within general open surgical skills, laparoscopic skills, and endoscopic skills, and a few specific procedures such as appendectomy and cholecystectomy were included in the final prioritized list.

CONCLUSION

Based on the Delphi process 13 technical skills and clinical procedures were included in the final prioritized list, which can serve as a point of departure when developing simulation-based training in surgery.
