Does specialization improve outcome in abdominal aortic aneurysm surgery?
Specialization and high volume are reported to be related to a better outcome after abdominal aortic aneurysm repair. The aim of this study was to compare, in patients undergoing abdominal aortic aneurysm repair, the outcomes of those whose surgery was done by general surgeons with the outcomes of those whose surgery was done by specialist vascular surgeons. All patients undergoing abdominal aortic aneurysm repair at the Basel University Hospital (referral center) from January 1990 to December 2000 were included. Patients with endovascular treatment were excluded. Operations in group A (n = 189), between January 1990 and May 1995, were done by general surgeons. Operations in group B (n = 291), between June 1995 and December 2000, were done by vascular surgeons. In-hospital mortality and local and systemic complications were assessed. In-hospital mortality rates were significantly lower for group B (with specialist surgeons) than for group A, both overall (group B, 11.7%; group A, 21.7%
