Vascular surgery in the United States: workforce issues. Report of the Society for Vascular Surgery and the International Society for Cardiovascular Surgery, North American Chapter, Committee on Workforce Issues.

The Committee on Workforce Issues of the Society for Vascular Surgery (SVS) and the North American Chapter, International Society for Cardiovascular Surgery (NA-ISCVS) generated data on the numbers and trends of operations performed and workforce requirements to provide surgical care of patients with vascular disease. Data for analysis were obtained from The National Center for Health Statistics-National Hospital Discharge Survey and questionnaires sent to 2732 vascular surgeons. The data showed that SVS/NA-ISCVS and regional vascular society (RVS) surgeons performed 51% of 583,000 vascular procedures undertaken in the United States in 1992. This represents a 24% increase over the 41% reported in 1985 by similarly defined surgeons. Analysis of 1992 index cases documented that SVS/NA-ISCVS and RVS surgeons accounted for 80% of 31,000 aortoiliofemoral bypasses, 68% of 46,000 aortic aneurysmectomies, 64% of 91,000 carotid endarterectomies, and 72% of 98,000 angioaccess procedures. The mean numbers of vascular operations performed in 1992 by SVS/NA-ISCVS and RVS surgeons were 144 and 100, respectively. These procedures represented 64% and 39% of the total surgical caseload of SVS/NA-ISCVS and RVS surgeons, respectively. American Board of Surgery (ABS)-certified vascular surgeons performed a mean of 171 vascular operations in 1992. Other surgeons, including ABS-certified general surgeons, appear to be performing fewer vascular operations. The latter fact and the increasing incidence of vascular disease in an expanding elderly population supports a continued need for vascular surgery specialists. Evolving technology and new health care delivery systems, however, may lessen the need for surgical care of these patients. Continued assessments of workforce activity will allow better definition of changing vascular surgery needs.
