Diffusion of Percutaneous Ventricular Assist Devices in US Markets.

ABSTRACT:

Background

Percutaneous ventricular assist devices (PVADs) have been replacing intra-aortic balloon pumps for hemodynamic support during percutaneous coronary intervention (PCI), even though data supporting a benefit for hard clinical end points remain limited. We evaluated diffusion of PVADs across US markets and examined the association of market utilization of PVAD with mortality and cost.

Methods

Using the 2013 to 2019 Medicare data, we identified all patients aged ≥65 years who underwent PCI with either a PVAD or intra-aortic balloon pump. We used hospital referral region to define regional health care markets and categorized them in quartiles based on the proportional use of PVADs during PCI. Multilevel models were constructed to determine the association of patient, h
