Systemic barriers to optimal hemodialysis access

Abstract

Arteriovenous fistulas (AVFs) are considered the gold standard for hemodialysis vascular access based on their superior patency, low complication rates, improved adequacy, lower costs to the health care system, and decreased risk of patient mortality. The goals of the Fistula First Breakthrough Initiative are to achieve a prevalent AVF use rate of at least 66% nationally, to decrease central venous catheter use, and to reduce overall vascular access complication rates among patients on hemodialysis. Achieving optimal vascular access is a complex process and, unlike other dialysis outcomes, requires patient involvement as well as collaboration among nephrologists, surgeons, interventionalists, dialysis facilities, primary care physicians, and hospital systems. In 2009, the Fistula First Breakthrough Initiative assembled a team from varied backgrounds and perspectives to discover the systemic root causes as to why the AVF use rate in the United States is significantly lower than that in other industrialized countries. Ultimately, the 139 latent root causes identified by the root cause analysis team fall into the categories of patient, physician, and system. This article summarizes the current controversies in regard to improving AVF placement and reducing central venous catheter use, related to each of these three categories.
