The recent escalation in lower extremity revascularization procedures suggests a concomitant increase in peripheral arterial disease (PAD) screening. We hypothesized that self-referring physicians would show the greatest growth in noninvasive physiologic testing for PAD and similar trends for revascularization procedures. We compared utilization rates for self-referring specialties (vascular surgery, interventional radiology, and cardiology) with the utilization rate for a referral-based specialty (diagnostic radiology), assuming the latter to be "basal"--that is, responsive only to changes in demographics and medical knowledge.
