Trends in General Surgery Operative Experience Obtained by Integrated Vascular Surgery Residents

OBJECTIVE: When the integrated vascular surgery training pathway was introduced, training was comprised of nearly equal amounts of core general surgery and vascular surgery experience. However, specific requirements for case numbers or types were not defined. Over time, the time spent on core general surgery requirements has been reduced, most recently in 2018, from 24 to 18 months. We sought to determine trends in general surgery case volume and type over the past 10 years for vascular surgery residents. METHODS: We conducted a retrospective review of the Accreditation Council for Graduate Medical Education case log data for integrated vascular surgery graduates from 2012-2018. We evaluated trends in mean numbers of cases, categorized as general surgery open (GS-open), general surgery laparoscopic (GS-laparoscopic), vascular surgery open (VS-open), and vascular surgery endovascular (VS-endo). Cases were also categorized by anatomic region as head/neck, thoracic, or abdominal. RESULTS: The mean number of total head/neck, thoracic, or abdominal cases logged by graduating integrated vascular surgery trainees was 263.5. This total, as well as the proportion of general surgery cases (35%-38%, p = 0.99) has remained constant over time. The type of general surgery cases has changed significantly, with an upward trend in the mean number of GS-open cases and downward trend in mean GS-laparoscopic cases (GS-open p = 0.006, GS-laparoscopic p = 0.048). Among head/neck and thoracic subgroups, no significant changes were observed, while in the abdominal subgroup, there has been a significant increase in GS-open over time (p = 0.005). Additionally, the number of open vascular abdominal aortic cases has remained stable, with an average of 36.82 per graduating trainee per year. CONCLUSIONS: In the 10 years since the introduction of integrated vascular surgery programs, total case volume and proportion of general surgery cases have remained remarkably stable. The type of general surgery cases has shifted though, with a decrease in GS-laparoscopic cases, replaced primarily by open abdominal cases. These changes likely reflect integrated vascular residents actively seeking out these opportunities during their core rotations and a willingness by general surgery partners to provide these opportunities. At the program level, these data may help guide program directors' choices about the specific core rotations they incorporate into their curriculum. At the national level, this information may contribute to future discussions regarding the optimal number of core general surgery rotation requirements.

Automated summary

Over the past decade, integrated vascular surgery trainees have maintained stable total case volume and proportion of general surgery cases, with a shift in the type of general surgery cases towards fewer GS-laparoscopic cases and more open abdominal cases.
