Vascular surgery training in the United States, 1994 to 2003

The Impact of Endovascular Repair of Abdominal Aortic Aneurysms on Vascular Surgery Training in Open Aneurysm Repair

BACKGROUND

Since the introduction of endovascular aneurysm repair (EVAR) in 1992, the number of open AAA repair (OAR) cases continue to decline. The consequence of reduced OAR cases raises valid concerns related to patient safety and the future training of vascular surgeons that need to be appropriately addressed. Our objective is to analyze trends in OAR and EVAR cases and to assess their implications on the quality of vascular surgery training.

METHODS

We analyzed the Accreditation Council for Graduate Medical Education (ACGME) case log database for total clinical experience in OAR and EVAR for graduating vascular surgery fellows (VSFs) finishing 5 + 2 programs between 2002 and 2019 and vascular surgery integrated residents (VSRs) between 2013 and 2019. VSF case totals were calculated by combining average total cases of open and endovascular supra- and infrarenal AAA repair during fellowship years combined with total cases performed during their general surgery residency. VSR case totals included only the cases performed during the 5-year residency period. Isolated Iliac and thoracic aortic aneurysms were excluded from our analysis.

RESULTS

The average number of OAR cases per trainee has decreased by 60% (from 36.9 to 14.7) with a rate of 1.4 cases per year (P < 0.001) for VSF. Meanwhile, EVAR average cases have increased by 102% (from 22 to 44.4). However, there were 2 different trends exhibited with EVAR over the study period. Between 2002 and 2007, EVAR cases tended to increase by 5.9 cases per year (P < 0.001). Whereas, between 2007 and 2019, there was a slightly decreased trend in EVAR cases by 0.3 cases per year (P = 0.01). For VSR, while no significant trend was observed in the mean number of OAR cases (Coef. -0.3, P = 0.2) due to the limited time frame, the proportion of open cases was significantly lower compared to endovascular cases. Additionally, there were 2 different trends exhibited with EVAR over the study period. Between 2013 and 2015, EVAR cases tended to increase by 1.7 cases per year (P = 0.1). Whereas, between 2015 and 2019, there was a slightly decreased trend in EVAR cases by 0.2 cases per year (P = 0.007).

CONCLUSIONS

A significant reduction in average OAR cases and an increase in EVAR cases were observed over the study period. Vascular surgery training programs may need to introduce further training programs in open surgical repair to ensure vascular surgery trainees have the required technical skills and expertize to perform such a high-risk procedure safely and independently.

Virtual Simulation of Intra-operative Decision-Making for Open Abdominal Aortic Aneurysm Repair: A Mixed Methods Analysis

OBJECTIVE

To create and pilot test a novel open abdominal aortic aneurysm (AAA) repair virtual simulation focused on intraoperative decision-making. To identify if the simulation replicated real-time intra-operative decision-making and discover how learners' respond to this type of simulation.

DESIGN

An explanatory sequential mixed methods study. We developed a step-by-step outline of major intra-operative decision points within a standard open AAA repair. Perioperative and intraoperative decision-making trees were developed and coded into an online virtual simulation. The simulation was piloted. Quantitative data was collected from the simulation platform. We then performed a qualitative thematic analysis on feedback from interviewed participants.

SETTING

Four academic general and vascular surgical training programs across the US.

PARTICIPANTS

Seventeen vascular and general surgery trainees and 6 vascular surgery faculty.

RESULTS

Participants spent on average 27 minutes (range: 8-45 minutes) interacting with the interface. 93% of participants reported feeling they were making real intraoperative decisions. 85% said it added to their knowledge base. 96% requested additional simulations. 22 interviews were completed: 241 primary codes were collapsed into 21 parent codes, and 6 emerging themes identified. Themes included the benefit of how (1) "Virtual Learning Could Standardize the Training Experience"; how (2) "Dealing with the Unexpected" as a trainee is an important part of surgical education growth, and that this (3) "Choose Your Own Adventure" virtual format simulates this intraoperative growth experience. Participants requested a (4) "Looping Feature Feedback Diagram" for future simulation iterations and highlighted that (5) "Fancier is Not Necessarily More Educational." Finally, many trainees wondered about (6) "The Attending Impact" from the simulation: if faculty would notice a difference between trainees who did vs did not utilize the simulation for case preparation.

CONCLUSIONS

Operative simulation training should focus on both technical skills and intra-operative decision-making, particularly "dealing with the unexpected." The learners' responses indicate that a low-fidelity, scalable, virtual platform can effectively deliver knowledge and allow for intra-operative decision-making practice in a remote learning environment.

Factors Affecting the Interest in a Surgical Career among Medical Students at a Nonurban, Tertiary Care Academic Institution

BACKGROUND

Present day medical students are inherently different from those in the past by growing up in a uniquely different environment that shapes their personal and professional values which affects their career decisions. Vascular surgery (VS) task force is facing a shortage in the near future. The purpose of this analysis is to gain a better understanding of the medical students' perceptions about surgery in general and VS in particular. Our institution is a large, tertiary care medical center, which is in a nonurban location. Our goal was to identify any barriers in the recruitment of prospective students to VS and to implement directives to address such barriers.

METHODS

An online questionnaire was distributed to Penn State Hershey College of Medicine medical students. Our institution has an established 0 + 5 VS residency program and a VS interest group. It was designed to understand potential barriers in the recruitment of medical students choosing VS as a career. Survey consisted of 23 questions, which were carefully designed to collect information about student demographics, interest in medical profession in general, opinions about the field of surgery, and reasons for having an interest or no interest in VS.

RESULTS

Five hundred sixty medical students at Penn State Hershey College of Medicine were surveyed, of whom 143 (26%) completed the survey. About 58.7% were females and two-thirds of the respondents were in the age range of 21-25 years. The following factors were significantly associated with pursing surgical career: Medical Student Year III (odds ratio [OR] 0.36, confidence interval [CI] 0.19-0.69), surgical mentorship (OR 6.01, CI 1.30-28), wanting more exposure to VS (OR 6.15, CI 2.07-18.23), and opportunity to complete training within 5 years (OR 1.14, CI 1.03-1.25) (all P < 0.05). Specifically, for VS, following factors were found to be associated with increased likelihood of choosing a VS career: variety of operative cases, ability to operate on multiple anatomic areas of the body, and opportunity to complete training within 5 years (all P < 0.05). Following factors were associated with not choosing a VS career: surgical career not for me, long duration of surgical training, financial aid burden, marital status, and complexity of operations (all P < 0.05). Students cited following concerns for choosing a surgical career: burnout (61%), stress (12.8%), work hours (12.1%), and stressful life style (5.7%).

CONCLUSIONS

Potential barriers of students in choosing a surgical career are fundamentally grounded in their overall perception of surgery but are independently associated with their level of education (medical student-III versus others), strong surgical mentorship, the desire to be exposed to VS, and the opportunity to complete subspecialty surgical training within 5 years. For VS, attractive factors were variety of operative cases, ability to operate on multiple anatomic areas of the body, and opportunity to complete training within 5 years. Overall, burnout associated with surgical career is the most common concern for medical students.

Vascular surgery: taking the next steps toward autonomy

The recognition of vascular surgery as an independent surgical specialty is inevitable, but the pathway to full autonomy remains uncertain. Vascular surgery emerged from general surgery in the mid-1950s with the advent of synthetic grafts and microvascular techniques. By the early 1980s, Accreditation Council for Graduate Medical Education-approved fellowships were established in most large academic medical centers. The American Board of Surgery recognized this additional specialty training by awarding vascular graduates a Certificate of Special Qualifications distinguishing them from general surgeons. The emergence of endovascular surgery radically changed the face of vascular surgery from a general surgery subspecialty to a unique surgical specialty with a growing array of minimally invasive tools. With the establishment of a primary Certificate in Vascular Surgery and the subsequent development of integrated residencies, vascular surgery moved ever closer to recognition as an independent surgical specialty. Despite the remarkable progress that has been observed over the past 50 years, there is a desire in the vascular community for formal recognition of the unique body of knowledge and surgical skills that serve as the foundation of contemporary vascular care.

Vascular fellow and resident experience performing infrapopliteal revascularization with endovascular procedures and vein bypass during training

OBJECTIVE

Endovascular aneurysm repair has led to a significant reduction in vascular trainee experience in the surgical treatment of aortic aneurysms. We sought to evaluate whether the vascular training paradigm or the "endovascular first" approach to lower extremity vascular disease has had a similar effect on trainee experience with infrapopliteal endovascular therapy and vein bypass.

METHODS

Deidentified data were provided by the Vascular Surgery Board on the number of procedures performed by each 2014 fellowship and residency (0 + 5) graduate during training. Data were analyzed using parametric and nonparametric methods, where appropriate.

RESULTS

Of 125 trainees (109 fellows, 16 residents), 33 (27%) performed 10 or fewer infrapopliteal vein bypasses and 37 (29%) performed 10 or fewer infrapopliteal endovascular procedures during their training. Eleven trainees (9%) performed 10 or fewer of both procedures. There was a positive correlation between number of infrapopliteal vein bypass and endovascular procedures performed (r = 0.19; P = .03). There was no difference between fellows and residents in the mean number of bypass operations performed during training (17.3 vs 19.1; P = .50; range, 0-53). However, residents performed more infrapopliteal endovascular procedures than fellows did (median, 29 vs 16; P = .03; range, 0-128).

CONCLUSIONS

More than one in four graduates of both training paradigms finish with a low number of infrapopliteal bypasses and endovascular interventions. The number of these procedures needed for proficiency is not known. Vascular surgery training programs should critically evaluate the number of infrapopliteal procedures required to achieve proficiency.

Early vascular consultation in the setting of oncologic resections: benefit for patients and a continuing source of open vascular surgical training

BACKGROUND

Oncologic surgeons have become more aggressive at tumor resections that often require complex open vascular interventions. Vascular surgeons may be consulted preoperatively to aid in these cases, or commonly called into the operating room for an urgent consult. These operations provide a challenge to the vascular surgeon and also an opportunity for open vascular surgical training of residents. We present our experience with vascular surgical interventions during oncologic resections.

METHODS

A retrospective review of a prospectively maintained vascular registry was performed to identify patients undergoing vascular surgery in the setting of oncologic resections. Tumor histology, location, type of vascular intervention, vascular, and oncologic outcomes were recorded and reviewed.

RESULTS

Over a 7-year period, 21 oncologic cases involving vascular surgeons were identified. Tumor types included sarcoma (9), adenocarcinoma (4), germ cell (4), paraganglioma (2), and others (2). Tumor locations included abdominal/pelvic (15), cervical (3), and extremity (3). Complete resection was achieved in 18 of the 19 patients; 2 patients underwent exploration alone for carcinomatosis. Vascular surgical procedures included bypass grafts in 7 patients, resection with primary repair in 5 patients, ligation/excision in 4 patients, and arterial mobilization in 3 patients. No major vascular complications occurred. Short-term patency rates were 100%. Survival rates following therapeutic resection were 90%, 80%, and 80% at 1, 3, and 5 years, respectively. Vascular surgeons were involved in the preoperative planning in 11 cases (52%). Patients with preoperative vascular consultation had significantly fewer vascular injuries, a nonsignificant trend toward lower blood loss, and a nonsignificant trend toward improved survival than those with urgent intraoperative vascular consultation.

CONCLUSIONS

Vascular interventions can lead to favorable long-term outcomes during definitive oncologic resection of diverse tumor histologies and locations. Vascular surgeons must be prepared to participate, frequently urgently, in oncologic procedures. Standard open techniques employing all aspects of vascular exposures continue to be integral to vascular surgery training. Preoperative consultation between the oncologic and vascular surgeons may lead to improved outcomes.

Simulator training on pulsatile vascular models significantly improves surgical skills and the quality of carotid patch plasty

OBJECTIVE

Vascular surgeons perform numerous highly sophisticated and delicate procedures. Due to restrictions in training time and the advent of endovascular techniques, new concepts including alternative environments for training and assessment of surgical skills are required. Over the past decade, training on simulators and synthetic models has become more sophisticated and lifelike. This study was designed to evaluate the impact of a 3-day intense training course in open vascular surgery on both specific and global vascular surgical skills.

METHODS

Prospective observational cohort analysis with various parameter measurements of both surgical skills and the technical quality of the finished product, performed before and after 3 days of simulator training of 10 participants (seven male and three female) in a vascular surgery training course. The simulator model used was a conventional carotid endarterectomy with a Dacron patch plasty on a lifelike carotid bench model under pulsatile pressure. The primary end points were assessment of any changes in the participants' surgical skills and in the technical quality of their completed carotid patches documented by procedure-based assessment forms. Scores ranging from 1 (inadequate) to 5 (excellent) were compared by a related-sample Wilcoxon signed test. Interobserver reliability was estimated by Cronbach's alpha (CA).

RESULTS

A significant improvement in surgical skills tasks was observed (P < .001). The mean score increased significantly by 21.5% from fair (3.43 ± 0.93) to satisfactory (4.17 ± 0.69; P < .001). The mean score for the quality of the carotid patch increased significantly by 0.96 (27%) from fair (3.55 ± 0.87) to satisfactory (4.51 ± 0.76; P < .01). The median interassessor reliability for the quality of the carotid patch was acceptable (CA = 0.713) and for surgical skills was low (CA = 0.424).

CONCLUSIONS

This study shows that lifelike simulation featuring pulsatile flow can increase surgical skills and technical quality in a highly sophisticated multistep vascular intervention. This training provides comparatively inexpensive and lifelike training possibilities for the adoption and assessment of surgical skills required to perform delicate vascular surgical procedures.

The impact of endovascular procedures on fellowship training in lower extremity revascularization

OBJECTIVE

The introduction of endovascular aneurysm repair has resulted in a decline in open abdominal aortic aneurysm repairs performed by vascular residents. The purpose of this study was to evaluate if a similar trend has occurred with open lower extremity revascularization procedures, with increased endovascular procedures producing a decrease in the number of open lower extremity revascularizations. Furthermore, this study evaluates the effect of endovascular procedure volume on the frequency of subtypes of open lower extremity procedures performed.

METHODS

The total number of vascular procedures, lower extremity bypasses, and endovascular interventions from 2000 to 2010 were analyzed from case logs of vascular residents as reported by the Accreditation Council for Graduate Medical Education.

RESULTS

The average number of cases performed by vascular residents has increased by 150% from 463.9 in 2000 to 1168 in 2009, due to the increased number of endovascular procedures. The average number of endovascular revascularizations has increased by 317% from 40.5 performed in 2000 to 168.9 in 2009. Femoral-popliteal bypasses have increased in frequency by 27% whereas the number of infrapopliteal bypass has remained unchanged. The largest difference is seen in femoral endarterectomies with a 234% increase from 3.2 per resident in 2001 to 10.7 per resident in 2010. Comparison of the proportion of femoral-popliteal and tibioperoneal interventions performed by angioplasty or bypass after 2007 revealed that endovascular interventions comprise 50% of procedures in the femoral-popliteal distribution, whereas 65% of infrapopliteal interventions are still performed using open techniques.

CONCLUSIONS

The number of procedures performed during vascular residency has dramatically increased over the last decade secondary to the increased number of endovascular procedures. The average vascular surgery resident's open operative experience has been stable over the last 10 years, despite the increasing endovascular case volume. Residents perform femoral endarterectomy with increasing frequency, perhaps representing an increasing volume of hybrid procedures. Gaps in information available for evaluating resident training remain a significant obstacle. Moving forward, revision of the current reporting system to a format that more accurately reflects resident experience would be beneficial.

Qualitative Impact of the Endovascular Era on Vascular Surgeons’ Comfort Level and Enjoyment With Open and Endovascular AAA Repairs

Objective: To evaluate the qualitative impact of training in the endovascular era (post-2000) on vascular surgeons’ comfort level and enjoyment with abdominal aortic aneurysm (AAA) repairs. Methods: A sample of vascular surgeons (n = 1754) were sent a survey pertaining to their fellowship training and practice of AAA repair. The influence of training- and practice-related variables on qualitative outcomes was assessed. Results: A total of 382 (22%) surgeons completed the survey. Surgeons who performed more endovascular aneurysm repairs (EVARs) than open AAA repairs were more likely to enjoy EVAR ( P < .001). Those completing fellowship after 2000 reported a higher level of procedure-related comfort with EVAR ( P = .001) compared to those completing fellowship before 2000. Conversely, surgeons completing fellowship before 2000 reported a higher level of procedure-related comfort with open AAA repair ( P = .001). Conclusion: The advent of EVAR has changed fellowship training of AAA repair and has translated into changes in both practice patterns and comfort level.

Vascular surgery training trends from 2001-2007: A substantial increase in total procedure volume is driven by escalating endovascular procedure volume and stable open procedure volume

BACKGROUND

Endovascular procedure volume has increased rapidly, and endovascular procedures have become the initial treatment option for many vascular diseases. Consequently, training in endovascular procedures has become an essential component of vascular surgery training. We hypothesized that, due to this paradigm shift, open surgical case volume may have declined, thereby jeopardizing training and technical skill acquisition in open procedures.

METHODS

Vascular surgery trainees are required to log both open and endovascular procedures with the Accreditation Council for Graduate Medical Education (ACGME). We analyzed the ACGME database (2001-2007), which records all cases (by Current Procedural Terminology [CPT] code) performed by graduating vascular trainees. Case volume was evaluated according to the mean number of cases performed per graduating trainee.

RESULTS

The mean number of total major vascular procedures performed per trainee increased by 174% between 2001 and 2007 (from 298.3 to 519.2). Endovascular diagnostic and therapeutic procedures increased by 422% (from 63.7 to 269.1) and accounted for 93.0% of the increase in total procedures. The number of open aortic procedures (aneurysm, occlusive, mesenteric, renal) decreased by 17.1% (from 49.7 to 41.2), while the number of endovascular aortic aneurysm repair procedures increased by 298.8% (from 16.9 to 50.5). Specifically, open aortic aneurysm procedures decreased by 21.8%, aortobifemoral bypass increased by 3.2%, and open mesenteric or renal procedures decreased by 13%. Infrainguinal bypass procedures remained relatively constant (from 37.6 to 36.5, 2.9% decrease), and the number of carotid endarterectomy procedures performed did not change significantly (from 43.6 to 42.2, 3.2% decrease).

CONCLUSION

Vascular surgery trainees are performing a vastly increased total number of procedures. This increase in total procedure volume is almost entirely attributable to the recent increase in endovascular procedures. Aside from a small decline in open aortic procedures, the volume of open surgical procedures has largely remained stable. It is essential that vascular surgery training programs continue to focus on both endovascular and open surgical skills in order for vascular surgeons to remain the premier specialists to care for patients with vascular disease.

Self-assessment of the Training of Vascular Fellows: Survey Results of 219 Vascular Fellows From 2004 Through 2007

Introduction. In an attempt to identify the concerns of vascular fellows regarding their training in vascular surgery, we conducted a survey consisting of 22 questions at an annual national meeting from 2004 to 2007. Methods. The fellows were asked to assess various aspects of their training as excellent, satisfactory, or mixed. Results. 76% were satisfied with their endovascular experience during their fellowship while 82% were satisfied with their experience with open cases. The distribution of non-learning cases was felt to be excellent, satisfactory, or required some or much improvement in: 45%, 44%, 8%, and 2% respectively. However, only 61% felt that their vascular laboratory experience was excellent or satisfactory. Only 36% actually performed the vascular duplex exam, and only 49% felt that they would feel comfortable in managing a vascular laboratory. Conclusions. The results of this Survey suggest that several significant issues are reflected in the minds of vascular trainees.

219 vascular fellows' perception of the future of vascular surgery

In an attempt to identify the fellows' concerns about the future of the field of vascular surgery, we conducted a survey consisting of 22 questions at an annual national meeting in March from 2004 to 2007. In order to obtain accurate data, all surveys were kept anonymous. The fellows were asked (1) what type of practice they anticipated they would be in, (2) what the new training paradigm for fellows should be, (3) to assess their expectation of the needed manpower with respect to the demand for vascular surgeons, (4) what were major threats to the future of vascular surgery, (5) whether they had heard of and were in favor of the American Board of Vascular Surgery (ABVS), (6) who should be able to obtain vascular privileges, and (7) about their interest in an association for vascular surgical trainees. Of 273 attendees, 219 (80%) completed the survey. Males made up 87% of those surveyed, and 60% were between the ages of 31 and 35 years. Second-year fellows made up 82% of those surveyed. Those expecting to join a private, academic, or mixed practice made up 35%, 28%, and 20% of the respondents, respectively, with 71% anticipating entering a 100% vascular practice. Forty percent felt that 5 years of general surgery with 2 years of vascular surgery should be the training paradigm, while 45% suggested 3 and 3 years, respectively. A majority, 79%, felt that future demand would exceed the available manpower, while 17% suggested that manpower would meet demand. The major challenges to the future of vascular surgery were felt to be competition from cardiology (82%) or radiology (30%) and lack of an independent board (29%). Seventeen percent were not aware of the ABVS, and only 2% were against it; 71% suggested that vascular privileges be restricted to board-certified vascular surgeons. Seventy-six percent were interested in forming an association for vascular trainees to address the issues of the future job market (67%), endovascular training during fellowship (56%), increasing focus on the vascular fellows at national meetings (49%), and representation for the fellows on the national councils (37%). This survey suggests that several significant issues exist in the minds of vascular trainees that have not been addressed and may present opportunities for further dialogue.

Future of vascular surgical training: the trainees' views

INTRODUCTION

In the UK, surgical training includes all aspects of general surgery. Vascular surgery is not an independent specialty. We wished to assess the views of vascular trainees in UK on the future of vascular surgery and training.

MATERIALS AND METHODS

Trainees were surveyed in 2003, 2004 (after introduction of the European Working Time Directive) and 2005, concentrating on four areas - future practise of vascular surgery, role of endovascular training, vascular specialisation and future training.

RESULTS

The majority of trainees want to practise vascular surgery alone. In 2003, 80% thought training should include endovascular techniques. By 2005, all trainees regarded training as mandatory as endovascular techniques would represent a significant part of their future work. Opinion changed on training; from 4 years general then 2 years vascular surgery (qualification in general surgery) to 2 years general and 4 years vascular surgery (specialist qualification in vascular surgery; P < 0.0001). Opinion also changed, that vascular surgery should spilt from general surgery to form its own speciality (P < 0.0007).

CONCLUSIONS

Trainees now regard training in endovascular techniques and endovascular aneurysm repair as mandatory. The majority wish to specialise from general surgery and achieve a separate qualification in vascular surgery.

Have endovascular procedures negatively impacted general surgery training?

OBJECTIVE

Technological advances in vascular surgery have changed the field dramatically over the past 10 years. Herein, we evaluate the impact of endovascular procedures on general surgery training.

METHODS

National operative data from the Residency Review Committee for Surgery were examined from 1997 through 2006. Total major vascular operations, traditional open vascular operations and endovascular procedures were evaluated for mean number of cases per graduating chief general surgery resident (GSR) and vascular surgery fellow (VSF).

RESULTS

As endovascular surgical therapies became widespread, GSR vascular case volume decreased 34% over 10 years, but VSF total cases increased 78%. GSR experience in open vascular operations decreased significantly, as evidenced by a 52% decrease (P < 0.0001) in elective open AAA repair. VSFs have also seen significant decreases in open vascular procedures. Experience in endovascular procedures has increased for both general surgery and vascular residents, but the increase has been much larger in absolute number for VSFs.

CONCLUSIONS

GSR experience in open vascular procedures has significantly decreased as technology has advanced within the field. Unlike VSFs, this loss has not been replaced by direct experience with endovascular training. These data demonstrate the impact technology can have on how we currently train general surgeons. New educational paradigms may be necessary in which either vascular surgery as an essential component is abandoned or training in catheter-based interventions becomes required.

Vascular surgery training and certification: An international perspective

OBJECTIVE

Vascular surgery (VS) practice has expanded to incorporate interventional procedures, and this has stimulated changes in training. The purpose of this study was to review current VS training and certification in different countries.

METHODS

A survey was completed by vascular surgeons involved with national certification in 34 countries. Results are expressed as the mean +/- SD, with comparisons by chi(2) and t tests.

RESULTS

VS is currently an independent specialty in 15 surveyed countries, is a subspecialty of general surgery in 10 countries, and is not recognized as a specialty in nine countries. There has been a clear time trend toward independent certification. In countries with independent VS certification, the length of VS training is 3.7 +/- 0.9 years plus 2.3 +/- 0.7 years of associated core general surgery (GS), for a total training length of 5.9 +/- 1.0 years. In countries with VS subspecialty certification, the length of VS training is 2.4 +/- 0.5 years after 5.0 +/- 1.1 years of GS, for a total training length of 7.4 +/- 1.2 years (each P < .01 vs independent certification). The minimum required volume of major open VS operations during training is 151 +/- 78 in countries with independent VS certification vs 113 +/- 53 in countries with subspecialty certification. Endovascular requirements for training are established in 71% of countries with independent certification vs 37% of countries with subspecialty certification (P < .03). Countries with independent VS certification produce 5.4 +/- 2.8 VS trainees per year per million population 65 years of age or older, vs 3.0 +/- 1.8 in countries with subspecialty certification (P < .02).

CONCLUSIONS

Considerable variation exists in VS training in different countries. There is an international movement toward independent VS certification, with longer VS specific training but shorter overall residency duration. Counties with independent VS certification produce more trainees per year to serve their elderly population.

What impact might general surgery practice patterns of colon and rectal surgeons have on future training?

Currently, surgeons specialize in colon and rectal surgery after a complete residency and certification in general surgery. The American Board of Surgery is proposing reorganization of surgical training; only two to four years of general surgery would be required followed by two to three years of specialization. The general surgery practice patterns of colon and rectal surgeons are unknown. The purposes of this study were to evaluate the current practice patterns of colon and rectal surgeons and to quantify the frequency and type of general surgical procedures performed. Active candidates, members, and fellows of The American Society of Colon and Rectal Surgeons were asked to complete an online survey. Results collected from November 18 to 26, 2004 were included. Data were self-reported. A total of 772 surgeons were included in the analysis; 7 percent were candidates, 29 percent were members, and 64 percent were fellows. Sixty-three percent had been practicing for 20 years or less and 64 percent were younger 50 years of age. Colon and rectal practice consisted of 28 percent abdominal surgery, 14 percent laparoscopic surgery, 28 percent anorectal surgery, and 30 percent endoscopy. Fifty-six percent of colon and rectal surgeons reported performing general surgery procedures with an average of 25 percent of their practice being general surgery. The most common procedures were herniorrhaphy (87 percent), cholecystectomy (76 percent), and appendectomy (33 percent). The most common reasons for general surgery practice were practice (52 percent) and emergency room requirements (43 percent). Currently, colon and rectal surgeons perform general surgery procedures in clinical practice. If general surgery residency of future trainees is shortened, the types of procedures colon and rectal surgeons will be competent to perform may need to be redefined. This will have profound implications on training programs, certification requirements, and future practice patterns.

Identification of Skills Common to Renal and Iliac Endovascular Procedures Performed on a Virtual Reality Simulator

INTRODUCTION

There is a learning curve in the acquisition of endovascular skills for the treatment of vascular disease. Integration of Virtual reality (VR) simulator based training into the educational training curriculum offers a potential solution to overcome this learning curve. However evidence-based training curricula that define which tasks, how often and in which order they should be performed have yet to be developed. The aim of this study was to determine the nature of skills acquisition on the renal and iliac modules of a commercially-available VR simulator.

METHOD

20 surgical trainees without endovascular experience were randomised to complete eight sessions on a VR iliac (group A) or renal (group B) training module. To determine skills transferability across the two procedures, all subjects performed two further VR cases of the other procedure. Performance was recorded by the simulator for parameters such as time taken, contrast fluid usage and stent placement accuracy.

RESULTS

During training, both groups demonstrated statistically significant VR learning curves: group A for procedure time (p<0.001) and stent placement accuracy (p=0.013) group B for procedure time (p<0.001), fluoroscopy time (p=0.003) and volume of contrast fluid used (p<0.001). At crossover, subjects in group B (renal trained) performed to the same level of skill on the simulated iliac task as group A. However, those in group A (iliac trained) had a significantly higher fluoroscopy time (median 118 vs 72 secs, p=0.020) when performing their first simulated renal task than for group B.

CONCLUSION

Novice endovascular surgeons can significantly improve their performance of simulated procedures through repeated practice on VR simulators. Skills transfer between tasks was demonstrated but complex task training, such as selective arterial cannulation in simulators and possibly in the real world appears to involve a separate skill. It is thus suggested that a stepwise and hierarchical training curriculum is developed for acquisition of endovascular skill using VR simulation to supplement training on patients.

Vascular Surgery Training after Primary Certification: Where We Go from Here

Program directors in vascular surgery have an increasingly complex set of responsibilities in the management of a vascular surgery residency, now that primary certification has been approved for vascular surgery and new training paradigms have been created in addition to the previous sequential training and certification in both general and vascular surgery. With the availability of new training paradigms, such as the 3+3 curriculum or entrance into a vascular residency program of 5 or 6 years directly out of medical school, the program director will become responsible for ensuring adequate training in basic surgical principals as well in the management of vascular pathology. Areas of added responsibility will include recruiting trainees, maintaining training case volumes, developing effective educational curricula and certifying the quality of the residents. This article discusses these tasks in detail, identifying special problem areas, such as changing lifestyle expectations, particularly in recruiting women, now approaching one half of medical students; expansion to meet the increasing need for vascular surgeons in the future as the population ages; funding vascular fellowship training; maintaining open surgical case loads while providing the facilities and supervision for adequate endovascular surgical training; providing a useful experience in both noninvasive vascular diagnosis and nonoperative management of vascular disease--in short, an experience that will result in Board certification and obtaining hospital privileges and a career that satisfies their choice of vascular surgery as a specialty.

The new training paradigms and the unfilled match positions of 2004: Will history repeat itself?

OBJECTIVE

The new millennium has seen an increase in vascular residency vacancies. The American Board of Vascular Surgery recently proposed new training paradigms, but their impact on recruitment remains unknown. We surveyed vascular fellows regarding factors and timing of career decisions to determine an optimal strategy for recruitment.

METHODS

Surveys were sent electronically to vascular residents for completion. Data were analyzed using SPSS software. Additional data were obtained from the National Resident Matching Program.

RESULTS

Of the 90 fellows that responded, 84% committed to vascular surgery during residency. Of these, 18% decided during postgraduate year 1, 54% by year 2, 84% by year three, and 95% by year 4. Sixteen percent of all trainees decided in medical school. Seventy-three percent of residents performed a minimum of 20 to 50 cases before reaching a decision. Among the group deciding between years 2 to 4 of residency, there was a significant difference in the number of vascular rotations before career commitment (P = .0001). In the 2004 Match, 21% of vascular residency positions were unfilled, up from 12% in 2003, 9% in 2002, and 4% in 2001.

CONCLUSIONS

Leaders in the field of vascular surgery have proposed focused training through the new paradigms. The incline in unmatched vascular residency positions over the past 4 years highlights the importance of a strategic plan to optimize recruitment. Few current trainees decided early in training about career choice, and volume appears critical to the decision process. Utilizing the current matching system (an 18-month process) and without any proactive change in recruitment, an integrated program after medical school would be reasonable for only 16% of applicants, or the 3+3 option for 54% of residents. For the new paradigms to be successful and to prevent more unfilled positions, increased medical student integration into vascular rotations and early active exposure to endovascular and open procedures during general surgical training will be necessary across the country.

Different Endovascular Referral Patterns Are Being Learned in Medical and Surgical Residency Training Programs

Physicians in residency training will be the referring physicians of tomorrow. We sought to determine the current surgical and medical trainees' perception of vascular surgery's endovascular qualifications and capabilities. An anonymous survey was sent to all general surgery and internal medicine residents at a single academic institution. Respondents answered the question "Which specialty is the most qualified to perform (1) inferior vena cava (IVC) filter insertion; (2) angiograms, angioplasty, and stenting of the carotid arteries; (3) renal arteries; (4) aorta; and (5) lower extremity arteries?" For each question, respondents chose one response, either vascular surgery, interventional radiology, interventional cardiology, or do not know. One hundred respondents completed the survey (general surgery, n=50; internal medicine, n=50). There was a significant difference in the attitudes of surgery and medicine residents when choosing the most qualified endovascular specialist (p<0.05). Surgery residents chose vascular surgery as the most qualified specialty for each listed procedure: carotid (80%, n=40), IVC (56%, n=28), aorta (100%, n=50), extremity (86%, n=43), renal (78%, n=39). Medicine residents chose vascular surgery as the most qualified specialty less frequently: carotid (66%, n=33), IVC (6%, n=3), aorta (88%, n=44), extremity (72%, n=36), renal (16%, n=8). There was no significant difference in specialty selection based on postgraduate year. There is a large discrepancy between surgical and medical trainees' perception of vascular surgery's endovascular abilities, particularly regarding IVC placement and renal artery interventions. If our own institution mirrors the nation, each passing year a significant portion of the 21,722 graduating internal medicine residents go into practice viewing vascular surgeons as second-tier endovascular providers. A concerted campaign should be undertaken to educate medical residents regarding the skills and capabilities of vascular surgeons.

Characteristics of the applicant pool to vascular surgery residency programs

OBJECTIVE

Based on the significant number of unfilled vascular fellowship positions in the 2004 National Residency Matching Program (NRMP) and the perception of program directors that the quality of candidates is deteriorating, the Issues Committee of the Association of Program Directors in Vascular Surgery (APDVS) explored the characteristics and the trend of the applicant pool to develop recommendations for improvement.

METHODS

The Electronic Residency Application Service (ERAS) database was queried for the total number of applicants, medical school, gender, and age, among other characteristics. The vascular surgery applicant pool was compared to the applicant pool for general surgery; the applicant pool for all fellowship positions, including a variety of medical subspecialties; the applicant pool for all residency positions; and the applicant pool for colorectal surgery, the only other surgical subspecialty participating in ERAS in 2004. NRMP data was used prior to 2004. The chi(2) test was used for statistical analysis, with significance set at P < .05.

RESULTS

In the 2004 match for June 2005 positions, there were 100 applicants for 110 first-year vascular surgery positions in 90 programs. In 1989, there were 123 applicants for 56 positions in 49 programs. In 1989, 55% of vascular surgery applicants did not match; whereas in 2004, only 7% were unmatched. Although the overall number of vascular surgery applicants has remained relatively stable, the number of United States applicants has decreased from 89% in 1990 to 68% in 2004 (P < .01). There was a significant geographic variation: 34% of those in the applicant pool came from the state of New York, but 23 states did not contribute a single applicant to the pool. In addition, vascular surgery, like other fellowships, attracts fewer female applicants.

CONCLUSIONS

The data from the ERAS database support the impression held by many in the vascular surgery education community that the size of the applicant pool for vascular surgery fellowship positions has remained stagnant, while the number of positions has significantly increased. Strategies to increase the size and quality of the applicant pool are needed.
