title: Volume-outcome relationship for peripheral endovascular interventions: a review of existing literature.
abstract: The incidence and prevalence of peripheral vascular disease has been increasing. When coexistent with coronary artery disease (CAD), it has shown to predict higher mortality along with poorer quality-of-life consequently leading to a marked increase in healthcare costs. Broadly, there has been an increase in utilization of endovascular techniques in the management of peripheral vascular diseases. An inverse relation between volume and outcomes has been noted in these procedures. Additionally, improved resource utilization has also been noted with higher hospital and operator volumes. This has led to proposals to regionalize these procedures to high volume hospitals. There have also been calls to introduce the idea of having a set threshold of procedures for providers. This review presents an overview of published literature on the volume-outcome relationship affecting the outcomes of peripheral endovascular procedures.
