Peritoneal dialysis (PD) is a well-established renal replacement therapy
for end-stage renal disease patients. Nonetheless, on an annual basis, at
least 10% of patients shift from PD to hemodialysis for a variety of reasons.
Thus the issue of vascular access creation needs to be addressed for this
small but significant group of patients. Despite the relatively consistent
number of dropouts, the creation of an arteriovenous fistula prior to transfer
remains suboptimal, and variable from center to center. Literature for this
specific area is poor and dated. Guidelines seem to suggest vascular access
creation in high-risk failure patients, but they have no detailed criteria to
select patients that would likely fail PD and therefore take advantage of a
backup access. There is a need to better understand and predict patients that
require conversion to hemodialysis to develop a plan that focuses on wellness
and maximum quality of life in the lifecycle of PD patients. This review
addresses the issue of vascular access planning in adult PD patients, presents
the available literature on the topic and the current guidelines and
recommendations, and describes a research agenda to guide decision making in
clinical practice.
