The role of the Vascular Surgery Board in surgical education

Vascular Surgery In-Training Examination performance following implementation of the Vascular Surgical Council on Resident Education curriculum

OBJECTIVE

The Vascular Surgery Surgical Council on Resident Education (VSCORE) program is a standardized curriculum intended to prepare Vascular Surgery trainees for the annual Vascular Surgery In-Training Examination (VSITE). This study evaluated the performance of 0+5 and 5+2 Vascular Surgery trainees on the VSITE prior to and following implementation of the VSCORE curriculum.

METHODS

VSITE scores, measured as percentage of questions correct, were collected for Vascular Surgery trainees at a United States academic medical center between 2015 and 2022. The VSITE scores were compared for the periods prior to (2015-2021) and following (2022) implementation of the VSCORE curriculum.

RESULTS

Fifty-seven VSITE scores were evaluated, including 46 examinations completed prior to and 11 after the implementation of the VSCORE curriculum. The mean VSITE score across all training levels (post-graduate year [PGY] 1-7) increased significantly from 68.4% ± 1.5% prior to implementation of VSCORE curriculum to 76.5% ± 3.1% following implementation (P = .03). Two-way analysis of variance identified pre- and post-VSCORE implementation as a statistically significant categorical variable when residents were stratified into junior (PGY 1-2), senior (PGY 3-5), and fellow (PGY 6-7) training levels (P < .001). The mean change in score between consecutive years also increased following VSCORE implementation (14.1% ± 2.3%) compared with the pre-VSCORE era (5.7% ± 1.7%; P = .002) CONCLUSIONS: The implementation of the VSCORE curriculum at an academic medical center improved VSITE scores across vascular surgery trainees at all levels.

A modern appraisal of current vascular surgery education

OBJECTIVE

Although general program requirements and curriculum content outlines are provided by the Accreditation Council for Graduate Medical Education, Association for Program Directors in Vascular Surgery, and Vascular Surgery Board of the American Board of Surgery, there is no single format for delivery of this content. The delivery of these defined educational components is, thus, likely to differ from site to site. The curriculum committee of the Association of Program Directors in Vascular Surgery was tasked with formalizing the content of the Vascular Surgery Surgical Council on Resident Education curriculum modules, and, therefore, we sought to appraise the current status of vascular educational programs in U.S. training programs before its implementation.

METHODS

Program directors (PDs) of 112 U.S. vascular surgery residency and fellowship training programs were contacted via email and asked to participate in an anonymous electronic survey. This survey evaluated the educational components of individual programs, including vascular specific conferences, use of other training modalities, and determination of who was involved in the creation of these programs.

RESULTS

Of the 112 PDs offered the survey, 80 (71%) responded. Most (42 of 80; 53%) have both an integrated vascular residency and a fellowship with the remaining being solely fellowship (31 of 80; 39%) or integrated residencies (7 of 80; 9%). The majority (79 of 81; 98%) of programs hold at least one vascular conference per week, with 75% (60 of 81) holding more than one each week. The total time spent in conference averaged 2.6 hours/wk, and the most common educational components of the weekly conferences were review of upcoming (48 of 79, 61%) or recently completed surgical cases (30 of 79; 38%), lectures on vascular disease processes (40 of 79; 51%), and review of book chapters from vascular surgery textbooks (27 of 78; 35%). PDs are responsible for creating the schedule at 50% (39 of 78) of the programs with most remaining programs relying on trainees (18 of 78; 23%) and assistant PDs (17 of 78; 22%). Vascular trainees present the majority of material at most programs' conferences (64 of 77; 83%). The majority of PDs feel that trainees should independently study 4 hours or more per week (51 of 79; 65%), but only 25% (20 of 79) believe that trainees actually spend this amount of time studying (P = .0001). Only 13 of 80 (16%) programs currently use a preformatted standardized vascular curriculum, but 64 of 80 (80%) believe that there is a need for the creation of this product and 72 of 80 (90%) would most likely use it.

CONCLUSIONS

There is a significant variation in vascular surgery educational programs with considerable dependence on trainees to create the curriculum. The majority of PDs in vascular surgery support the creation of a standardized vascular curriculum and would use it if made.

Failure on a Vascular Surgery Board-American Board of Surgery Examination does not predict cardiovascular outcomes in the Society for Vascular Surgery Vascular Quality Initiative

OBJECTIVE

The Vascular Surgery Board of the American Board of Surgery (VSB-ABS) Qualifying and Certifying examinations are meant to assess qualifications to independently practice vascular surgery, but it is unclear whether examination performance correlates with clinical outcomes. We assessed this relationship using clinical outcomes data for VSB-ABS diplomates from the Society for Vascular Surgery Vascular Quality Initiative (SVS-VQI).

METHODS

VSB-ABS examination performance for vascular surgeons participating in the SVS-VQI registry was characterized according to pass/fail status. Surgical experience was measured by number of years since completion of training. Examination performance and experience were compared with a composite clinical outcome (in-patient major adverse cardiac events or postoperative death [MACE+POD]) after arterial reconstructions (carotid stenting or endarterectomy, aortic aneurysm repair, open peripheral surgical bypasses) registered in the SVS-VQI. Multivariate mixed effects regression was performed adjusting for sex and surgery type, as well as clustering by surgeon and by hospital.

RESULTS

From 2003 to 2017, complete data were available for 776 vascular surgeons who performed 124,171 arterial reconstructions (carotid n = 56,650; aortic n = 34,764; peripheral n = 32,757) registered in the SVS-VQI. Patient characteristics associated with higher odds of MACE+POD were female sex (odds ratio [OR] 1.07; 95% confidence interval [CI], 1.03-1.12; P = .006) and advancing age (OR, 1.04; 95% CI, 1.03-1.04; P < .001). Of the 776 surgeons, 149 (17%) had failed at least one VSB-ABS examination (group F). The unadjusted primary composite outcome of MACE+POD was marginally higher after operations performed by surgeons who never failed an examination (group P; 7% vs 6%; P = .03). This difference seems to be driven by higher rates of postoperative congestive heart failure in the aortic and lower extremity bypass cohorts as well as more postoperative myocardial infarctions after lower extremity bypass by group P surgeons. Following multivariable analyses, examination pass status was not associated with MACE+POD (OR, 0.98; 95% CI, 0.89-1.50; P = .517). However, increasing surgical experience correlated with significantly lower odds of MACE+POD (2% lower odds/year of experience since training [OR, 0.98; 95% CI, 0.98-0.99; P < .001]).

CONCLUSIONS

VSB-ABS examination performance by SVS-VQI surgeons does not correlate with registry-reported mortality or cardiovascular complications. Increasing surgical experience is strongly associated with lower odds of cardiovascular morbidity and death.
