Impact of the 80-hour workweek on surgical case exposure within a general surgery residency program

[Learn playfully, operate seriously : The new era of surgical training]

BACKGROUND

Traditional surgical training and further education has historically involved long working hours and hands-on experience within the framework of a teacher-apprentice relationship; however, changes in regulatory policy in the USA and subsequently in Switzerland and the European Union from 2003, led to restrictions in the working hours of medical residents. As a result the traditional method of surgical training "see one, do one, teach one" has come under scrutiny, prompting a search for alternative training methods beyond the confines of the operating theater.

OBJECTIVE

This publication highlights the possibilities and limitations associated with the use of virtual reality (VR) and gamification in surgical training and further education. It examines the ability of these technological resources to enhance the effectiveness and engagement of medical residents and the feasibility of incorporating them into the surgical training curriculum.

MATERIAL AND METHODS

The study was based on a literature search for current developments in surgical training, VR and gamification. Furthermore, various studies and projects that investigated the use of VR and gamification in medical training and further education were analyzed.

RESULTS AND DISCUSSION

In this investigation it could be shown that the use of VR reduces the perioperative risks and improves the training environment and learning. The use of gamification also increases the motivation and engagement of the medical residents. As a result the quality of medical education can be improved by the fusion of VR and gamification.

The Impact of Simulator Training of Vascular Anastomosis and Video Assessment for Surgical Residents

BACKGROUND

The rapid increase of minimally invasive surgery and the shortened training period for surgical residents has resulted in limited opportunities to acquire proficiency in open surgical techniques, such as vascular anastomosis. However, vascular anastomosis remains an essential skill in every surgery for bleeding control. This study aimed to validate the effectiveness of surgical education model for vascular anastomosis and assess the impact on the comprehension, skill, and confidence of surgical residents in performing vascular anastomosis.

METHODS

A total of 21 surgical residents with first to third years of experience at Seoul National University Hospital participated in a 4-week vascular anastomosis training program. The program included an educational lecture and the performance of an end-to-side anastomosis on a procedural model, with evaluations being conducted using the Objective Structured Assessment of Technical Skills (OSATS) and the End-Product Rating Score (EPRS) in pretraining and posttraining surveys.

RESULTS

Significant improvement was observed in the OSATS score (from 9.22 ± 2.4 in week 1 to 12.87 ± 3.1 in week 4; P < 0.001) and the EPRS score (from 12.47 ± 4.1 in week 1 to 17.57 ± 2.2 in week 4; P < 0.001). Additionally, the surgical performance time significantly decreased from 20.99 ± 4.6 min to 16.33 ± 4.2 min (P = 0.019) CONCLUSIONS: Simulator training of in vitro vascular anastomosis, when accompanied by expert-led instruction, can effectively enhance the surgical proficiency, confidence, and overall surgical outcomes of residents, as inferred from the observed improvements in OSATS and EPRS scores. The results suggest that integration of this training model into surgical curricula could be a promising strategy for enhancing vascular surgical training.

A Mixed-Methods Needs Assessment for a Longitudinal Surgical Preparation Course in Undergraduate Medical Education

OBJECTIVE

To assess the unmet needs associated with surgical education and skill development during the pre-clerkship years of medical school.

DESIGN

A mixed-methods design was employed that leveraged semi-structured interviews and quantitative surveys followed by qualitative analysis.

SETTING

A large midwestern academic medical center.

PARTICIPANTS

Eighteen participants were enrolled representing second year medical students with an interest in surgery, surgical residents, and attending surgeons from a diverse array of surgical specialties.

RESULTS

Unanimous support for the creation of a pre-clerkship surgical skills course emerged due to 2 main themes: (1) gaps in current surgical education offerings and (2) the value of early exposure to surgery and surgical skills followed by longitudinal practice. The components that participants deemed essential to a well-designed course were also revealed. Each stakeholder group (medical students, residents, surgeons) would benefit across all factors uncovered.

CONCLUSIONS

There is a significant unmet need across all stakeholder groups for the creation of a longitudinal surgical skills course for pre-clerkship medical students. Future studies should seek to design a curriculum based on these study results and assess a pilot version of the curriculum to understand its feasibility under application.

Art in Surgery: A Review of Art-based Medical Humanities Curricula in Surgical Residency

OBJECTIVE

Numerous programs integrate arts and humanities methods to advance medical education competencies. Despite the highly visual and technical nature of the field of surgery, the current state of art utilization in surgical training is unclear. The purpose of this review is to gain a comprehensive understanding of how art has been utilized in surgical training, to investigate the purpose of such interventions, and to assess how art interventions may benefit surgeons.

DESIGN

A systematic literature review using PRISMA methodology was conducted to identify articles published prior to February 2022 that investigated or described using art in surgical resident training. Qualitative themes were developed upon full review of the literature and categorized based on fundamental aspects of surgical education. The data was summarized by a narrative approach.

RESULTS

Six hundred seventy-four unique articles were initially identified, thirteen of which met inclusion criteria. Twelve studies employed drawing or sculpture in surgical residency training; one discussed art observation to foster mindfulness, teambuilding, and empathy. Eight articles utilized art as an evaluation tool, 2 for didactic and archival purposes, one employed exercises in art analysis to improve empathy and physician wellbeing, and 2 described courses in which art making was treated as a foundational skill. No articles discussed use of art for honing diagnostic skills, observation, or patient communication - competencies that have been addressed in other fields.

CONCLUSIONS

This review highlights the small number of examples in the medical literature about visual arts in surgical training. The existing art-based surgical humanities studies identify opportunities for curricular innovation within surgical training.

A survey of specialty choice among obstetrics and gynecology residents in Japan, Korea, and Taiwan

AIM

The percentage of medicine graduates opting for residency in obstetrics and gynecology (OB/GYN) has been decreasing in developed countries, including in Taiwan, Japan, and Korea. This multicountry study surveyed the OB/GYN residents affiliated with the Taiwan Association of Obstetrics and Gynecology (TAOG), the Japanese Society of Obstetrics and Gynecology (JSOG), and the Korean Society of Obstetrics and Gynecology (KSOG) to evaluate the factors affecting the choice of pursing OB/GYN.

METHODS

A 17-item questionnaire surveying the factors influencing the choice of pursuing a major medical specialty was translated into Japanese, Korean, and Chinese and administered to postgraduate OB/GYN residents between July 1, 2020, and August 31, 2020. Data on the participants' sex, age, and level of residency were collected. Responses were compared between countries and sexes.

RESULTS

Residents of all three countries chose OB/GYN based on personal interest, and a sense of accomplishment in saving people's life. Other positive factors include improved quality of life; higher salaries; and more opportunity for new techniques, research, and promotion. The negative factors included medical litigations, longer work hours, and unsafe working environments. Korean residents had lower ratings in several items, including "support from family," "safety of working environment," and "effectiveness of the alternative dispute resolution system," which, unlike Japan and Taiwan, is not a no-fault compensation system for childbirth accidents.

CONCLUSIONS

The study findings can guide strategy making, such as decreasing workload and yet maintain training quality, to increase the number of medical students pursuing OB/GYN residency.

Design and Validity Evidence for a Unique Endoscopy Simulator Using a Commercial Video Game

Background Procedural simulation enhances early endoscopy training. Multiple commercial simulators are available; however, their application is limited by cost and poor user compliance. First-person "shooter" (FPS) video games are popular. In this study, we aimed to show that a novel in-house designed colonoscope controller used to play an FPS video game shares similar constructs with real-life endoscopy. Methodology Participants completed the first three levels on an FPS video game, Portal (Valve Corporation, Bellevue, WA), first using a conventional controller and then the modified endoscope controller. A total of 12 expert endoscopists and 12 surgical residents with minimal endoscopy experience were evaluated based on completion time, button presses, and hand motion analyses. Results Experts outperformed novices for completion time (expert: 944 seconds; novice: 1,515 seconds; p = 0.006) and hand movements (expert: 1,263.1; novice: 2,052.6; p = 0.004) in using the novel colonoscope controller. There was no difference in button presses or total path length traveled. Furthermore, performance did not differ using conventional game controls. Conclusions Experts outperformed novices using the endoscope but not the conventional controller with respect to the economy of movement and completion time. This result confirms that our endoscope-controlled video game shares similar paradigms with real-life endoscopy and serves as a first step toward creating a more enjoyable and cheaper alternative to commercially available endoscopy simulators.

Who is Committed to Education? An Analysis of Surgical Education Research Publications

OBJECTIVE

Advances in surgical training have led to the recent emergence of surgical education research. While the importance of surgical education research is well recognized, not all surgical journals are publishing these works. The objective of this study was to analyze the volume and types of surgical education publications in general surgery and surgical subspecialty journals.

DESIGN

A PubMed search string was developed to identify surgical education publications in general surgery (GS, n = 10) and surgical subspecialty (SS, n = 16) journals from 2015 to 2019. Publications were catalogued into 7 categories: curriculum and/or teaching, trainee assessment, program evaluation, wellness and/or burnout, resident research, case outcomes with resident involvement, and other. Journals were also categorized by impact factor into 3 groups. Statistical analysis was performed using linear regression and Wilcoxon rank-sum to analyze differences in education publication number and percent between GS and SS journals, as well as between different impact factor groups.

RESULTS

The median proportion of surgical education publications was 1.2% (IQR 0.3-2.8%) of total publications for journals queried. The highest proportion of surgical education publications by a journal was 13.9%. All other journals had median ≤ 5.5%. GS journals had a significantly higher median percent of surgical education publications than SS journals (2.9% [IQR 1.7-4.8%] vs 0.5% [IQR 0.0-1.4%] p < 0.01). Additionally, no significant differences were found for number of surgical education publications when journals were categorized by IF (p > 0.05).

CONCLUSIONS

Education research is an important component of the surgical literature, with similar publication rates among journals of different impact factors. Publication volume is higher among general surgery than surgical subspecialty journals. With the ever-changing paradigm of surgical training, a rigorous scientific approach is needed to ensure effective training of future surgeons. Subspecialty journals should promote surgical education research to further understand and develop training in their field.

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.

Flipping the Classroom: An Evaluation of Teaching and Learning Strategies in the Operating Room

OBJECTIVES

With increasing restraints on resident's experiences in the operating room, with causes ranging from decreased time available to increasing operating room costs, focus has been placed on how to improve resident's education. The objectives of our study are to (1) determine barriers in education in the operating room, (2) identify effective learning and teaching strategies for residents in the operating room with a focus on the tonsillectomy procedure.

METHODS

An online survey was sent to all otolaryngology residents and residency programs for which contact information was available from January 2016 to March 2016 with 139 respondents. The 12-question survey focused on information regarding limitations to learning how to perform tonsillectomies as well as difficulties with teaching the same procedure. Resident responses were separated based on PGY level, and analysis was performed using t-tests and Chi squared analysis.

RESULTS

Common themes emerged from responses for both teaching and learning how to perform tonsillectomies. A significant limitation in learning the procedure was lack of visualization during the surgery (57% learning vs 60% teaching). For both learners and teachers, the monopolar cautery instrument was found to be the most preferred instrument to use during tonsillectomy (80% each). The majority of resident respondents (93%) felt that an instructional video would be beneficial for both learning and teaching the procedure.

CONCLUSIONS

Significant limitations for learning and teaching in the operating room were identified for performing tonsillectomies. Future endeavors will focus on resolving these limitations to improve surgical education.

An Interprofessional Senior Medical Student Preparation Course: Improvement in Knowledge and Self-Confidence Before Entering Surgical Training

PURPOSE

Senior medical students are variably prepared to begin surgical training; and a national curriculum was established through the American College of Surgeons to better prepare senior medical students for surgical training. The purpose of our course is to prepare senior medical students to more effectively enter surgical training programs. We recently enhanced our independently developed surgical training preparation course by increasing exposure to surgical anatomy, medical physiology, surgical skills, and point-of-care ultrasound. We evaluated the impact of our interprofessional training course to increase confidence and readiness among senior medical students entering surgical training.

METHODS

The course focused on pre- and post-operative patient care, surgical anatomy, human physiology, and bedside ultrasound. Didactic lectures in anatomy, human physiology, and bedside ultrasound were provided prior to all hands-on simulated patient care sessions and mock surgical procedures. To evaluate our interprofessional curriculum, we administered pre- and post-course surveys, pre- and post-course knowledge tests, and a final surgical anatomy laboratory practical examination to 22 senior medical students who were enrolled in the course. All students created a final surgical anatomy presentation.

RESULTS

The students demonstrated a 100% pass rate in surgical anatomy. The knowledge test, which included assessment of knowledge on perioperative surgical decision making, human physiology, and bedside ultrasound, demonstrated an average improvement of 10%. Statistically significant improvements in median confidence values were identified in 10 of 32 surveyed categories, including surgical skills (p < 0.05); 84% of student goals for the course were achieved. The medical students' surveys confirmed increased confidence related to the use of point-of-care ultrasound, teamwork experience, and basic surgical skills through small group interactive seminars and surgical simulation exercises.

CONCLUSION

Our preparation for surgical training course resulted in high student satisfaction and demonstrated an increased sense of confidence to begin surgical training. The 10% improvement in medical student knowledge, as evaluated by a written examination, and the significant improvement in confidence level self-assessment scores confirms this surgery preparation course for senior medical students successfully achieved the desired goals of the course.

Operating Room Times For Teaching and Nonteaching Cases are Converging: Less Time for Learning?

OBJECTIVE

To compare differences in operating room (OR) times between teaching and nonteaching cases across calendar years. We hypothesize that time devoted to intraoperative resident education is decreasing, therefore, OR times for teaching and nonteaching cases will be converging.

BACKGROUND

Teaching cases take longer than similar nonteaching cases, in part due to intraoperative resident education. Pressures to improve OR efficiency and patient safety may threaten resident education and leave less time for intraoperative learning; however, the magnitude of impact is unknown.

SETTING/PARTICIPANTS

National Surgical Quality Improvement Program (NSQIP) deidentified national databases from 2006 to 2012, queried for 30 most common General surgery procedures and case teaching status (i.e., teaching vs. nonteaching cases).

DESIGN

The NSQIP database was retrospectively reviewed to identify the 30 most common General Surgery procedures. Teaching cases included all operations in which a resident participated. Multivariable regression analyses were constructed to determine the impact of resident involvement on OR times, controlling for year, resident participation, procedure, and patient demographics and comorbidities. Difference-in-difference analysis was performed to assess OR time differences between teaching and nonteaching cases across calendar years and within subpopulations.

RESULTS

A total of 693,223 cases met inclusion criteria. Average overall OR times were 98.89 minutes (teaching) vs. 74.22 minutes (nonteaching), with a difference of 24.67 minutes (95% confidence interval [CI] 24.34-24.99 minutes, p < 0.001). In multivariable analyses, the difference between teaching and nonteaching cases was 21.94 minutes (95% CI = 21.11-22.76) in 2006 and 13.95 minutes (95% CI = 10.62-17.28) in 2012, with a difference-in-difference of 7.99 minutes per case. A similar trend was observed across individual PGYs and several individual procedures.

CONCLUSIONS

OR times for teaching and nonteaching cases converged by approximately 8 minutes per general surgery procedure during the 7-year study period, representing a 36% reduction in the difference between groups. We must seek to better understand the source of this convergence, and in doing so ensure to preserve and enhance the intraoperative learning experience of surgical trainees.

Where Has All the Complexity Gone? An Analysis of the Modern Surgical Resident Operative Experience

OBJECTIVES

The operative experience of today's general surgery (GS) residents are changing. The Surgical Council on Resident Education (SCORE) was founded to provide a standardized, competency-based curriculum. We set out to evaluate resident operative experience in core and advanced operations.

DESIGN

Accreditation Council for Graduate Medical Education (ACGME) national operative log reports from 2010 to 2018 were reviewed. Operative volume data for 344 operations were extracted and analyzed. Operations were designated as core, advanced, or undefined as listed by SCORE, and stratified as GS or subspecialty.

SETTING

National analysis utilizing ACGME operative log reports.

PARTICIPANTS

All graduating general surgery residents between 2010 and 2018.

RESULTS

A total of 10,118 residents completed GS training with an average of 1121.5 ± 29.3 total cases. Core operations comprised 80.5% of total volume while advanced comprised only 8.0%. The total core experience increased (+7.0 cases/year), while total advanced experience decreased (-1.4 cases/year) (p < 0.01 each). Compositional analysis among core operations revealed an increase in 9/13 GS domains and a decrease in 8/10 subspecialty domains (all p < 0.05).

CONCLUSIONS

There has been an increase in core operative experience with a concurrent decrease in advanced operative experience of graduating GS residents. These findings highlight the continued narrowing of the operative experience for trainees, with increasing focus on GS and less on subspecialty domains. Ongoing efforts to look beyond operative volume to ensure competency of graduates will prove beneficial.

Needs Assessment for Lower Urinary Tract Injury Curriculum for FPMRS Fellowships

OBJECTIVE

The aim of this study was to determine the level and types of training Accreditation Council for Graduate Medical Education-accredited programs use for female pelvic medicine and reconstructive surgery (FPMRS) fellows' education on lower urinary tract injuries (LUTIs).

METHODS

Two surveys were developed to assess the need for LUTI curriculum from both program director (PD) and fellow vantages through a multistage process, including review by knowledgeable colleagues, cognitive interviews, and pilot testing. Surveys were distributed in an electronic link via e-mail to graduating fellows and program directors from each of the 58 Accreditation Council for Graduate Medical Education-accredited FPMRS programs.

RESULTS

Thirty-four graduating FPMRS fellows (71%) and 39 FPMRS PDs (67%) completed the survey. Both PDs and fellows responded that both the evaluation and management of LUTI were necessary to FPMRS training. The majority of PDs use a combination of didactics and hands-on learning in the operating room (60% and 71%). Only 40% and 30% incorporate simulation into the curriculum to address LUTI. Graduating fellows report low numbers of procedures to evaluate and manage LUTI. Specifically, only 15% of fellows graduate with greater than 2 ureteral reimplantations and 44% graduate with no minimally invasive abdominal vesicovaginal fistula repairs. The majority of graduating fellows reported feeling prepared to evaluate for LUTI, but nearly one third do not feel ready to independently manage LUTI upon graduation.

CONCLUSIONS

FPMRS PDs and fellows agree that the evaluation and management of LUTI are important; however, most programs use only didactics and hands-on learning in the operating room with extremely low case volumes, leading to decreased proficiency.

Changing Hands: A Rising Role of the Tumor Surgeon in Teaching Sylvian Fissure Dissection

OBJECTIVE

The landscape of microneurosurgery has changed considerably over the past 2 decades, with a decline in indications for open surgery on cerebrovascular pathology and ever-increasing indications for open resection of brain tumors. This study investigated how these trends in case volume affected residents' training experiences in microsurgery and, specifically, Sylvian fissure dissection.

METHODS

Resident case logs were reviewed, identifying open cerebrovascular operations and craniotomies for tumor. Operations involving Sylvian fissure dissection were identified through operative reports. Changes in case number by resident were plotted over time, and linear regression was applied.

RESULTS

Among 23 chief residents, 3045 operations were identified, 1071 of which were for cerebrovascular pathology and 1974 for tumor. Open cerebrovascular experience decreased (P < 0.0001) while tumor volume remained unchanged (P = 0.221). The number of Sylvian fissure dissections per resident did not change over time overall (P = 0.583) or within cerebrovascular operations (P = 0.071). The number of Sylvian fissure dissections in tumor operations increased (P = 0.004). This effect was predominated by an increase in intraaxial tumors approached via Sylvian fissure dissection (P = 0.003). The proportion of Sylvian fissure dissections in tumor surgery increased from 15% in 2009 to 34% by 2019 (P = 0.003).

CONCLUSIONS

Residents are seeing an increasing proportion of their Sylvian fissure dissection experience during tumor operations. The distribution of this experience will continue to evolve as surgical indications change but suggests a growing role for tumor surgeons in resident training in microsurgery.

Review of Surgical Education Research Trends in North America

OBJECTIVE

The purpose of this study was to synthesize surgical education research literature over the last decade and to address the following questions: (1) What are the most common subjects studied? (2) What research designs and data-gathering strategies are commonly employed? (3) Where are these papers being published? (4) What subject and research design trends have emerged in the last decade?

DESIGN

A literature review was conducted on surgical education publications from January 2008 to July 2018, using the search terms, "Graduate Medical Education," and "General Surgery." Inclusion criteria included articles published in the United States and Canada specific to general surgery and graduate medical education.

RESULTS

A total of 1043 articles met inclusion criteria and were categorized according to year published, journal type, journal of publication, subject of research, research design, and data collection method. The following observations were noted: (1) curriculum/teaching remains the most common subject of surgical education research, with growing emphasis on program evaluation, well-being, duty hours, and case exposure. (2) Descriptive research is the most common, although qualitative and mixed methods research is becoming more common. (3) Online surveys are the most common data collection method as they are the quickest way to gather data but there is an increasing use of interviews as support for qualitative research grows. and (4) Surgical education papers are largely published in journals specifically designed for education, and have slowly grown in popularity in generalized surgical journals.

CONCLUSIONS

As surgical education continues to develop as a field, we anticipate further acceptance of qualitative research in major peer-reviewed surgical journals, increased emphasis on resident well-being, and more effective use of interviews and mixed methods including online resources for data collection.

The growing discrepancy between resident training in colonic surgery and the rising number of general surgery graduates

PURPOSE

The decrease in resident operative experience due to working-hour directives and sub-specialization within general surgery is the subject of growing debate. This study aims to examine how the numbers of colectomies used for resident training have evolved since the introduction of working-hour directives and to place these results within the context of the number of new general surgeons.

METHODS

Based on the nationwide database of the Swiss association for quality management in surgery, all segmental colectomies performed at 86 centers were analyzed according to the presence or absence of residents and compared to national numbers of surgical graduates.

RESULTS

Of 19,485 segmental colectomies between 2006 and 2015, 36% were used for training purposes. Residents performed 4%, junior staff surgeons 31%, senior staff surgeons 55%, and private surgeons 10%. The percentage performed by residents decreased significantly, while the annual number of graduates increased from 36 to 79. Multivariate analysis identified statutory (non-private) health insurance (OR 7.6, CI 4.6-12.5), right colon resection (OR 3.5, CI 2.5-4.7), tertiary referral center (OR 1.9, CI 1.5-2.6), emergency surgery (OR 1.7, CI 1.3-2.3), and earlier date of surgery (OR 1.1, CI 1.0-1.1) as predictors for resident involvement.

CONCLUSIONS

Only a low and declining percentage of colectomies is used for resident training, despite growing numbers of trainees. These data imply that opportunities to obtain technical proficiency have diminished since the implementation of working-hour directives, indicating the need to better utilize suitable teaching opportunities, to ensure that technical proficiency remains high.

National Trends in General Surgery Resident Exposure to Complex Oncology-Relevant Cases

OBJECTIVE

To evaluate trends in surgical resident exposure to complex oncologic procedures in order to determine whether additional fellowship training is necessary.

DESIGN

An observational study of national Accreditation Council for Graduate Medical Education case log statistical reports was conducted to determine the average number of cases for selected oncology-relevant procedures completed during training. Linear regression and Cusick trend tests were used to assess temporal trends with the null hypothesis assuming an estimated slope of zero. Instrumental variable estimation was used to study the effect of duty-hour restrictions on oncologic cases per year.

SETTING

United States general surgery residency training programs.

PARTICIPANTS

Graduating surgical residents completing their training between 2000 and 2016.

RESULTS

Across the study interval, mean case volume was 950.6 ± 29.7 (standard deviation) cases with 38.9 ± 3.1 complex oncologic cases per graduating resident. Decreasing trends were noted for average exposure to lymphadenectomies (-7.8 cases/decade; 95% confidence interval [CI] -8.8 to -6.8) and low rectal procedures (-0.9 cases/decade; 95% CI -1.2 to -0.6). There was no clinically important change in complex soft-tissue resections and foregut cases. A significant increase was seen in number of hepatopancreaticobiliary procedures (+3.9 cases/decade; 95% CI 3.1-4.7). Using instrumental variable estimation, there was a modest decline in cancer-relevant cases by 5.0 cases/decade (95% CI 4.5-5.6), while there was an increase in 38.5 total cases/decade (95% CI 10.4-66.7) associated with duty-hour restrictions.

CONCLUSIONS

Case numbers for several complex oncologic procedures remain low, justifying a need for further fellowship training depending on individual resident experience.

Comparative study of the operative experience of surgical residents before and after 80-hour work week restrictions

Purpose

In Korea, the working-hour limitation regulation has been implemented in December 2017. We aimed to define the difference in operative experience of surgical residents before and after implementing this policy in 2 hospitals among 8 affiliated hospitals of the Catholic Medical Center where implemented the 80 working-hour limitation policy since March 2015.

Methods

All the operation records were reviewed, and the number of resident-participated surgeries between March and August in 2002 and 2017 were compared. Operations performed or participated in by residents as first assistants were defined as resident participated surgery.

Results

After 2 years from the initiation of the resident work-hour limitations, the number of resident participated surgery has slightly decreased in both hospitals (Yeouido St. Mary's Hospital [YSM]: 317 to 302, St. Paul Hospital [SPH]: 635 to 461). For each resident, changes were like followings: 0 → 21 cases for R1, 65 → 72 cases for R2, 83 → 192 cases for R3, and 169 → 17 cases for R4 in YSM. In SPH, number of resident participating surgery was changed like followings: 4 → 32 cases for R1, 222 → 100 cases for R2, 317 → 300 cases for R3, and 92 → 29 cases for R4. In both hospital, while, total number of resident participating oncologic surgery has been decreased, number of resident participating appendectomy has been far increased. Activity of each grade resident is different according to hospital.

Conclusion

Although total number of resident participating surgery decreased, variable changes were observed in each grade of resident according to each type of surgery and different hospitals. It is believed that comparisons of experiences from more hospitals in the future would be helpful in establishing the guidelines for surgical experience requirement of residents in Korea.

Do Orthopaedic Resident and Fellow Case Logs Accurately Reflect Surgical Case Volume?

OBJECTIVE

The purpose of this study is to determine whether orthopedic resident and fellow case logs accurately reflect trainee case volume.

DESIGN

For each orthopedic case performed at our institution between 7/1/14 and 10/31/14, the names of trainees who participated were obtained from the chart. The trainee Accreditation Council for Graduate Medical Education case logs were queried to determine if the procedure in question was logged and, if so, which current procedural terminology (CPT) codes were reported. The CPT codes reported by the trainees were compared to those reported by the attendings in the billing database. To ascertain the opinions of trainees regarding coding, a survey was conducted.

SETTING

University of Maryland Medical Center (Baltimore, MD), a tertiary and quaternary care center which features a state-wide trauma referral center as well as orthopedic residency and fellowship training programs.

PARTICIPANTS

All orthopedic surgery residents and fellows present at the institution during the study period.

RESULTS

Trainees failed to log their cases 24% of the time (465/1925), including 25% (283/1117) for residents and 23% (182/808) for fellows (p = 0.16). Among cases that were logged, CPT codes were missed 46% of the time (673/1460) and extra codes were added 28% of the time (412/1460) compared to the attendings. In the survey, most trainees stated that it was "extremely" or "very" important for them to be able to code correctly (83%; 29/35).

CONCLUSIONS

In this study of orthopedic trainee case logging practices, cases were not logged 24% of the time. Caution should be taken with activities which rely on trainee case logs given the potential for inaccuracy.

Renal Transplantation as a Platform for Teaching Residents Open Vascular Surgical Techniques: Effects on Early Graft Function

BACKGROUND

Over the past decade, increases in vascular fellowships and the use of endovascular technology have decreased the general surgery residents' exposure to open vascular surgery. We sought to elucidate whether renal transplant is a safe way to teach general surgery residents the essential tenants of vascular surgery without adversely affecting early patient outcomes.

METHODS

All solitary, adult deceased donor kidney transplants performed at the University of Wisconsin from 2011 through 2016 were identified and divided into a resident-assist (RA) and fellow-assist cohorts (FA). DGF, defined by the requirement of dialysis within 1 week of transplant, was the primary outcome. Early graft survival and postoperative complications were considered the secondary endpoints.

RESULTS

Of the 774 total cases, there were 228 (29.5%) in the RA cohort and 546 (70.5%) in the FA cohort. The RA and FA cohorts had comparable characteristics, except for a nonclinically significant difference in mean donor creatinine (0.96 vs 0.88mg/dL, p = 0.03). RA cases had a similar DGF rate compared to FA cases (25% vs 26%, p = 0.93). Additionally, there was no difference in 2-year graft survival (93.7% vs 95.5%, p = 0.38), nor the rates of graft thromboses (0.4% vs 0.7%, p = 0.65), incisional hernias (0.9% vs 1.8%, p = 0.35), and ureteral strictures (2.2% vs 1.6%, p = 0.55) between the 2 cohorts.

CONCLUSIONS

Resident involvement in renal transplantation has no effect on DGF and early allograft function. Though the procedural involvement of each resident in a case is variable, it seems to be a safe way to teach retroperitoneal vascular exposure and anastomotic techniques.

Microsurgery Case Volume During Orthopedic Surgery Residency: A 7-Year Assessment

BACKGROUND

Microsurgery is a specialized surgical technique with wide clinical application. The purpose of this study was to analyze case logs of graduating orthopedic surgery residents to assess trends in case volume for microsurgery procedures.

METHODS

Accreditation Council for Graduate Medical Education case log reports were analyzed for microsurgery experience from 2007 to 2013. The mean number of adult, pediatric, and total microsurgery cases was noted. In addition, the median number of microsurgery procedures performed by the 90th, 50th, and 10th percentiles of residents (by case volume) was recorded. Temporal changes in case volume were calculated utilizing linear regression analyses.

RESULTS

The proportion of microsurgery procedures increased significantly (1.3% to 2%; P = .024). The mean number of adult (24.5 to 41.9; P = .01), pediatric (1.9 to 3.4; P = .011), and total (26.3 to 45.3; P = .01) microsurgery procedures also increased significantly. Similarly, residents in both the 90th (63 to 109; P = .01) and 50th (10 to 21; P = .036) percentiles sustained significant increases in the median number of microsurgery procedures. No change was noted for residents in 10th percentile (0 to 0; P > .999). Graduating residents in the 90th percentile performed over 6 times more microsurgery procedures than residents in the 50th percentile.

CONCLUSIONS

Microsurgical caseload is increasing among graduating orthopedic residents. However, there is substantial variability in resident microsurgery case volume. Future investigations are needed to explore the educational implications of these findings and should seek to correlate microsurgical caseload with competency.

Comparison of Canadian and Swiss Surgical Training Curricula: Moving on Toward Competency-Based Surgical Education

OBJECTIVE

Quality of surgical training in the era of resident duty-hour restrictions (RDHR) is part of an ongoing debate. Most training elements are provided during surgical service. As exposure to surgical procedures is important but time-consuming, RDHR may affect quality of surgical training. Providing structured training elements may help to compensate for this shortcoming.

DESIGN

This binational anonymous questionnaire-based study evaluates frequency, time, and structure of surgical training programs at 2 typical academic teaching hospitals with different RDHR.

SETTING

Departments of Surgery of University of Basel (Basel, Switzerland) and the Queen's University (Kingston, Ontario, Canada).

PARTICIPANTS

Surgical consultants and residents of the Queen's University Hospital (Kingston, Ontario, Canada) and the University Hospital Basel (Basel, Switzerland) were eligible for this study.

RESULTS

Questionnaire response rate was 37% (105/284). Queen's residents work 80 hours per week, receiving 7 hours of formal training (8.8% of workweek). Basel residents work 60 hours per week, including 1 hour of formal training (1.7% of working time). Queen's faculty and residents rated their program as "structured" or "rather structured" in contrast to Basel faculty and residents who rated their programs as "neutral" in structure or "unstructured." Respondents identified specific structured training elements more frequently at Queen's than in Basel. Two-thirds of residents responded that they seek out additional surgical experiences through voluntary extra work. Basel participants articulated a stronger need for improvement of current surgical training. Although Basel residents and consultants in both institutions fear negative influence of RDHR on the training program, this was not the case in Queen's residents.

CONCLUSIONS

Providing more structured surgical training elements may be advantageous in providing optimal-quality surgical education in an era of work-hour restrictions.

Variability in Surgical Case Volume of Orthopaedic Surgery Residents: 2007 to 2013

INTRODUCTION

Variability in orthopaedic surgery training is an important issue facing trainees. We examined orthopaedic surgery case logs for subspecialty case volume during residency training and assessed trends and variability in case volume over time. We hypothesized that there is variability in training in all subspecialties encountered in orthopaedic surgery resident training and that the volume of cases in each subspecialty has increased over time.

METHODS

Annual surgical case logs of the Accreditation Council for Graduate Medical Education from 2007 to 2013 for orthopaedic surgery residency were assessed for variability and case volume trends.

RESULTS

The average total adult cases logged per graduating resident in 2007 was 1,952, which increased to 2,291 in 2013, representing a 17.4% increase (P = 0.00041). The gap in case volume between residents in the 10th and 90th percentiles for case exposure decreased from 2007 to 2013 (P = 0.0268), although the 10th percentile group still logged significantly fewer procedures compared with the 90th percentile group in 2013 (P = 0.0159).

CONCLUSIONS

Although case volume is not the sole determinant of surgical skill and further study is needed to investigate the effects of training experience, this variability in surgical volume may affect the knowledge, skill, and practice patterns of surgeons.

Audiovisual preconditioning enhances the efficacy of an anatomical dissection course: A randomised study

The benefits of incorporating audiovisual materials into learning are well recognised. The outcome of integrating such a modality in to anatomical education has not been reported previously. The aim of this randomised study was to determine whether audiovisual preconditioning is a useful adjunct to learning at an upper limb dissection course. Prior to instruction participants completed a standardised pre course multiple-choice questionnaire (MCQ). The intervention group was subsequently shown a video with a pre-recorded commentary. Following initial dissection, both groups completed a second MCQ. The final MCQ was completed at the conclusion of the course. Statistical analysis confirmed a significant improvement in the performance in both groups over the duration of the three MCQs. The intervention group significantly outperformed their control group counterparts immediately following audiovisual preconditioning and in the post course MCQ. Audiovisual preconditioning is a practical and effective tool that should be incorporated in to future course curricula to optimise learning. Level of evidence This study appraises an intervention in medical education.

LEVEL OF EVIDENCE

Kirkpatrick Level 2b (modification of knowledge).

Decrease in junior resident case volume after 2011 ACGME work hours

OBJECTIVE

To determine how the new 2011 Accreditation Council for Graduate Medical Education work hours affected case volume across postgraduate year (PGY) levels of surgical trainees.

DESIGN

Retrospective review of Accreditation Council for Graduate Medical Education case logs of surgical residents at Beth Israel Deaconess Medical Center from 2006 to 2013.

SETTING

Tertiary care center.

PARTICIPANTS

All categorical surgical residents from 2006 to 2013.

RESULTS

PGY-1 cases decreased from 139 (122.25-172.5) to 111.5 (102.25-117.5) (p = 0.003). PGY-2 case volume decreased as well from 162 (151.5-192) to 126 (95.5-173) (p = 0.011). Only 45% of PGY-2 residents performed more than 250 major cases after the work hours changed compared with 82% of residents before 2011. PGY-3 cases increased from 263 (215-309) to 309 (282-340) (p = 0.0038). Cases performed by PGY-4 and PGY-5 residents were not statistically different. Total cases performed by graduating chiefs, however, has increased from 987 (848.5-1050) to 1090 (1033-1145) (p = 0.0006).

CONCLUSIONS

Intern and PGY-2 case volume has declined at our institution as new work-hour regulations took effect in 2011. However, PGY-3 case volume increased significantly, and graduating chiefs are graduating with more cases. The work hours do not appear to have had the intended result of improving intern educational experience from a standpoint of case volume. Significant programmatic changes will likely be required to achieve the 250-case minimum by the end of PGY-2 year, as per 2014 American Board of Surgery requirements.

Perceived effects of the 16-hour workday restriction on surgical specialties: Quebec's experience

OBJECTIVE

Quebec was the first Canadian province to implement a 16-hour workday restriction. Our aim was to assess and compare Quebec's surgical residents' and professors' perception regarding the effects on the educational environment, quality of care, and quality of life.

DESIGN

The Surgical Theater Educational Environment Measure, the Postgraduate Hospital Educational Environment Measure, quality of the medical act, and quality-of-life questionnaires were administered 6 months after the work-hour restrictions.

SETTING

Université de Montréal Surgery Department, Montréal, Québec, Canada; Université de Sherbrooke Surgery Department, Sherbrooke, Québec, Canada; Université Laval Surgery Department, Québec, Québec, Canada; and McGill University Surgery Department, Montréal, Québec, Canada.

PARTICIPANTS

Surgical residents and professors of all specialties within the 4 university surgery departments in Quebec through a voluntary web-based survey.

RESULTS

A total of 280 questionnaires were analyzed with response rates of 29.7% and 16.4% for residents and professors, respectively. Data were coded on a scale from 2 (strong improvement perception) to -2 (strong deterioration perception). The professors perceived a higher negative effect than the residents did on the educational environment, i.e., role of autonomy (-0.399 vs. -0.577, p < 0.001), teaching (-0.496 vs. -0.540, p < 0.001), social support (-0.345 vs. -0.535, p < 0.001), and surgical learning (-0.409 vs. -0.626, p < 0.001). The professors also observed a higher negative effect on patients' safety (-0.199 vs. -0.595, p = 0.003) and quality of care (-0.077 vs. -0.421, p = 0.014). The latter was even perceived as unchanged by residents (-0.077, 95% CI: -0.249 to 0.095). The residents perceived a negative effect on their quality of life, whereas the professors believed the contrary (0.500 vs -0.496, p < 0.001). More professors than residents believed residency should be prolonged (80.8% vs. 50.6%, p < 0.001).

CONCLUSIONS

Residents and professors perceive a mild negative effect on the educational environment and quality of care, whereas their perception on quality of life is opposite. The professors seem concerned about adequate training to the point of considering increasing training length.

The effect of duty hour regulation on resident surgical case volume in otolaryngology

OBJECTIVE

Evaluate the effect of duty hour regulation on graduating otolaryngology resident surgical case volume and analyze trends in surgical case volume for Accreditation Council for Graduate Medical Education (ACGME) key indicator cases from 1996 to 2011.

STUDY DESIGN

Time-trend analysis of surgical case volume.

SETTING

Nationwide sample of otolaryngology residency programs.

SUBJECTS

Operative logs from the American Board of Otolaryngology and ACGME for otolaryngology residents graduating in the years 1996 to 2011.

METHODS

Key indicator volumes and grouped domain volumes before and after resident duty hour regulations (2003) were calculated and compared. Independent t test was performed to evaluate overall difference in operative volume. Wilcoxon rank sum test evaluated differences between procedures per time period. Linear regression evaluated trend.

RESULTS

The average total number of key indicator cases per graduating resident was 440.8 in 1996-2003 compared to 500.4 cases in 2004-2011, and overall average per number of key indicators was 31.5 and 36.2, respectively (P = .067). Four key indicator cases showed statistically significant (P < .05) increases in volume after duty hour implementation. General/pediatrics was the only grouped domain to show a significant increase. In contrast, the rate of change in operative volume decreased post duty hour for only 2 key indicators (P < .05). The year-by-year trend in average operative volume showed significant increases for 5 key indicator cases (P < .05).

CONCLUSION

Implementation of the 2003 duty hour regulations has not reduced total volume of key indicator cases for graduating otolaryngology residents. The overall trend in operative volume is increasing for several specific key indicators.

A systematic review of the effects of resident duty hour restrictions in surgery: impact on resident wellness, training, and patient outcomes

BACKGROUND

In 2003, the Accreditation Council for Graduate Medical Education (ACGME) mandated 80-hour resident duty limits. In 2011 the ACGME mandated 16-hour duty maximums for PGY1 (post graduate year) residents. The stated goals were to improve patient safety, resident well-being, and education. A systematic review and meta-analysis were performed to evaluate the impact of resident duty hours (RDH) on clinical and educational outcomes in surgery.

METHODS

A systematic review (1980-2013) was executed on CINAHL, Cochrane Database, Embase, Medline, and Scopus. Quality of articles was assessed using the GRADE guidelines. Sixteen-hour shifts and night float systems were analyzed separately. Articles that examined mortality data were combined in a random-effects meta-analysis to evaluate the impact of RDH on patient mortality.

RESULTS

A total of 135 articles met the inclusion criteria. Among these, 42% (N = 57) were considered moderate-high quality. There was no overall improvement in patient outcomes as a result of RDH; however, some studies suggest increased complication rates in high-acuity patients. There was no improvement in education related to RDH restrictions, and performance on certification examinations has declined in some specialties. Survey studies revealed a perception of worsened education and patient safety. There were improvements in resident wellness after the 80-hour workweek, but there was little improvement or negative effects on wellness after 16-hour duty maximums were implemented.

CONCLUSIONS

Recent RDH changes are not consistently associated with improvements in resident well-being, and have negative impacts on patient outcomes and performance on certification examinations. Greater flexibility to accommodate resident training needs is required. Further erosion of training time should be considered with great caution.

Graduating general surgery resident operative confidence: perspective from a national survey

BACKGROUND

General surgical training has changed significantly over the last decade with work hour restrictions, increasing subspecialization, the expanding use of minimally invasive techniques, and nonoperative management for solid organ trauma. Given these changes, this study was undertaken to assess the confidence of graduating general surgery residents in performing open surgical operations and to determine factors associated with increased confidence.

METHODS

A survey was developed and sent to general surgery residents nationally. We queried them regarding demographics and program characteristics, asked them to rate their confidence (rated 1-5 on a Likert scale) in performing open surgical procedures and compared those who indicated confidence with those who did not.

RESULTS

We received 653 responses from the fifth year (postgraduate year 5) surgical residents: 69% male, 68% from university programs, and 51% from programs affiliated with a Veterans Affairs hospital; 22% from small programs, 34% from medium programs, and 44% from large programs. Anticipated postresidency operative confidence was 72%. More than 25% of residents reported a lack of confidence in performing eight of the 13 operations they were queried about. Training at a university program, a large program, dedicated research years, future fellowship plans, and training at a program that performed a large percentage of operations laparoscopically was associated with decreased confidence in performing a number of open surgical procedures. Increased surgical volume was associated with increased operative confidence. Confidence in performing open surgery also varied regionally.

CONCLUSIONS

Graduating surgical residents indicated a significant lack of confidence in performing a variety of open surgical procedures. This decreased confidence was associated with age, operative volume as well as type, and location of training program. Analyzing and addressing this confidence deficit merits further study.

Multifaceted longitudinal study of surgical resident education, quality of life, and patient care before and after July 2011

OBJECTIVES

Resident duty-hour regulatory changes in July 2011 led to dramatic modifications in the structure of many surgical training programs in the United States. These changes were hypothesized to have effects on the quality of life and education of residents, and the patient care they deliver. Our study aims to measure changes in these domains among junior and senior residents before and after implementation of the latest regulations.

DESIGN

Longitudinal cohort study comparing objective and subjective metrics of education, patient care, and quality of life among all surgical residents at one institution.

SETTING

Tertiary academic medical center.

PARTICIPANTS

All residents in the Department of Surgery over 2 years (n = 97) were included. The included electronic survey had 30 and 36 responses in 2011 and 2012, respectively (overall 68% response rate).

RESULTS

Operative cases increased for residents at all postgraduate year levels. No significant differences in in-training examination scores were observed. Comparison of subjective data from the program evaluation and developed survey revealed a significant decrease in perception of resident clinical skill development (4.31/5 in 2011 to 4.15/5 in 2012, p = 0.02). Residents reported decreased quality of operative experiences (83% to 59%, p = 0.04), and less independence evaluating patient problems (90% to 61%, p < 0.01). Levels of burnout were high in the entire group, but decreased significantly over the study period (93% and 75% in 2011 and 2012, respectively, p = 0.05), with the largest difference seen in individuals with "high burnout" (43% and 11%, in 2011 and 2012, respectively, p < 0.01). Residents met criteria for "sleepiness" before and after the 16-hour rule implementation (68% and 67%, in 2011 and 2012, respectively, p = 0.92).

CONCLUSIONS

Following the July 2011 duty-hour changes, surgical residents report a negative effect on their education, with decreased clinical skill progression and perceptions of operative experience quality and patient care independence. Improvements in quality of life metrics, including burnout, were observed.

Distance learning improves attainment of professional milestones in the early years of surgical training

A surgical sciences e-learning program designed to support academic development of trainees in the early years of surgical training was associated with improved success in surgical trainees' professional examination, positive student feedback, and significant academic attainment.

Objectives:

To assess the impact of a surgical sciences e-learning programme in supporting the academic development of surgical trainees during their preparation for professional examination.

Background:

In 2007, a 3-year online part-time Master of Surgical Sciences (MSc) degree programme was launched, utilizing an innovative platform with virtual case scenarios based on common surgical conditions addressed by the curriculum relating to the Membership Examination of the Royal Colleges of Surgeons (MRCS). Multiple-choice questions with feedback and discussion boards facilitated by expert clinical tutors provided formative assessment. Summative assessment comprised written examination at the end of each of the first 2 years (equivalent to MRCS level), culminating in submission of a research dissertation in year 3 toward an MSc.

Methods:

Students' age, gender, and level at entry to the programme were documented. Anonymized student feedback from 2008 to 2012 was examined using online questionnaires, and performance in the MSc programme was compared to MRCS examination outcomes for students who had consented to release of their results.

Results:

A total of 517 surgical trainees from 40 countries were recruited over the 6-year period, and 116 MSc students have graduated to date. Of 368 students, 279 (76%) were foundation doctors (interns) and had not commenced formal surgical training on enrolling in the MSc programme. However, level at entry did not influence performance (P > 0.05 across all 3 years). Average pass rates since the programme launched, for those students completing all of the required assessments, were 84% ± 11% in year 1, 85% ± 10% in year 2, and 88% ± 7% in year 3 of the MSc programme. MSc students had significantly higher MRCS pass rates than nonenrolled trainees (67% vs 51%, P < 0.01, n = 352). There was a significant correlation between MRCS examination performance and overall performance in the MSc (R² = 58%; P < 0.01, n = 37). Of 248 respondents, 202 (81%) considered that the MSc would improve their chances of gaining a surgical training post, and 224 (90%) would recommend the programme to their peers.

Conclusions:

The online MSc programme supports academic development of trainees in the early years of surgical training, is well received by students, and is associated with improved success in their professional examination.

SESC Practice Committee Survey: Surgical Practice in the Duty-hour Restriction Era

Debate continues as to the relevance of Accreditation Council for Graduate Medical Education (ACGME) duty-hour restrictions in actual practice and the adequacy of resident training in surgery. A survey of the membership of the Southeastern Surgical Congress using an Internet-based questionnaire was conducted: adherence to duty-hour restrictions, evidence of sleepiness and fatigue, opinions regarding the training, and clinical performance of surgeons who had trained after the institution of duty-hour restrictions in 2003 (termed “recently trained surgeons”). One hundred seventy-seven members respondents out of 1008 (18%). Most (101 of 170 [59%]) worked more than 80 hours in a week and half (86 of 174 [49%]) more than 24 hours consecutively once or more a month. Falling asleep inappropriately was reported by 6 to 12 per cent. Forty per cent (71 of 176) thought that graduates of residencies today are prepared for clinical practice. Those who had hired a recently trained surgeon believed the latter was sufficiently trained (61 of 123 [50%]) more often than those who had not hired one (10 of 51 [20%]; P = 0.006). Those with a new colleague gave first assistant help in 75 per cent (91 of 121) during the first year. Surgeons in practice regularly violate ACGME duty-hour restrictions. Many surgeons have doubts whether new graduates of residency training programs have adequate training to practice surgery. Those who have hired a new surgeon trained under duty-hour restrictions are more likely to be satisfied with the latter's training. Most new trainees receive direct assistance from their practice partners, continuing their training beyond residency.

Surgical residents' perception of competence and relevance of the clinical curriculum to future practice

INTRODUCTION

General surgery residents maintain a case log throughout residency in order to achieve a targeted number of designated operations. Program directors must certify that each graduate is competent to enter general surgery practice without direct supervision. Our purpose was twofold, to determine: 1) graduates' perception of competence and relevance of specific operations to their practice; and 2) if case volume is related to competence.

METHODS

Six classes from a general surgery residency program (n=26) were surveyed one year after graduation. The survey was piloted and revised base on findings. It listed 67 operations encompassing all facets of general surgery. Each operation corresponded to two four-point scales (strongly agree to strongly disagree). One scale was headed with "I was well prepared to work-up, independently perform the operation, and effectively care for the patient post-operatively" and the other "This operation is relevant to my current practice profile". A linear regression analysis was utilized to study the relationship between total case volume and overall competence. An unpaired T-test was utilized to study the relationship between volume of specific operations and perceptions of competence.

RESULTS

Twenty-two graduates completed the survey (85% response rate). All respondents felt prepared to perform 24% (16/67) of the operations. Fifty percent or more of respondents felt prepared to perform 91% (61/67) of the operations. Fifty percent or more did not feel competent performing the surgical treatment of necrotizing enterocolitis, orchiopexy, transhiatal esophagectomy, adrenalectomy, and open/endovascular abdominal aortic aneurysm repair. Twenty-six operations were felt to be irrelevant to the practice of 50% or more of graduates. No operation was unanimously felt to be relevant. For 12% of operations (8/67) at least 10% of graduates felt the operation was relevant to their practice but were not comfortable performing it. These operations (abdominoperineal resection, transanal excision of tumor, transhiatal esophagectomy, superficial inguinal lymph node dissection, right hepatectomy, whipple, colonoscopy, and adrenalectomy) were considered to be in need of educational improvement at a program level. After analyzing individual case logs, increased case volume only correlated with competence for esophagectomy (5 vs. 1 p = .014), EGD (32 vs. 9 p = .018), orchiopexy (2.5 vs. 0 p = .03), and adrenalectomy (3 vs. 1 p = .001). Total major operations performed did not correlate with overall competence (p = .12).

CONCLUSION

As program directors must document graduates' competency they must do so with confidence. Our results suggest graduates to not feel competent performing many operations, and several are relevant to their practice. Competence in all aspects of general surgery may be unrealistic, even with robust volume. These findings might help in the restructuring curricula of residency.

A virtual-reality subtotal tonsillectomy simulator

Objectives:

To develop a virtual-reality subtotal tonsillectomy simulation for surgical training.

Materials and Methods:

Computer models of a male patient's head and throat, and the surgical instrument, were created. These models were combined with custom-built simulation software. Recently developed tissue simulation technology that exploits recent developments in programmable graphics processing units was used to model tonsillar tissue in a way that allows surgical interaction whilst providing accurate tactile feedback. Current real-time rendering techniques were used to provide realistic visuals. Iterative refinements were made to the simulation, and in particular the tissue simulation, in consultation with relevantly experienced surgeons.

Results:

We have used newly developed tissue simulation technology to developed a novel virtual-reality subtotal tonsillectomy simulation for surgical training, the first of its kind.

Conclusion:

Early feedback suggests that this simulator can help surgeons to rapidly acquire subtotal tonsillectomy surgical skills in a risk-free and realistic virtual environment.
