Dr Indes and colleagues1 have analyzed the effects of physician and hospital volume (as well as specialty) on the outcome of endovascular intervention for aortoiliac occlusive disease, and the results are reassuring to all those who believe in the concept of “practice makes perfect.” Once again—not counterintuitively—high volume (for both physician and hospital) was associated with better outcomes, including reduced complications, reduced mortality, and reduced length of stay. However, surgeons were found to be less expensive than nonsurgical interventionalists—not an outcome that I would have predicted.
