Abstract
In-center hemodialysis (HD) remains the predominant dialysis therapy in patients with ESKD. Many patients with ESKD present in late stage, requiring urgent dialysis initiation, and the majority start HD with central venous catheters (CVCs), which are associated with poor outcomes and high cost of care. Peritoneal dialysis (PD) catheters can be safely placed in such patients with late-presenting ESKD, obviating the need for CVCs. PD can begin almost immediately in the recumbent position, using low fill volumes. Such PD initiations, commencing within 2 weeks of the catheter placement, are termed urgent-start PD (USPD). Most patients with an intact peritoneal cavity and stable home situation are eligible for USPD. Although there is a small risk of PD catheter-related mechanical complications, most can be managed conservatively. Moreover, overall outcomes of USPD are comparable to those with planned PD initiations, in contrast to the high rate of catheter-related infections and bacteremia associated with urgent-start HD. The ongoing coronavirus disease 2019 pandemic has further exposed the vulnerability of patients with ESKD getting in-center HD. PD can mitigate the risk of infection by reducing environmental exposure to the virus. Thus, USPD is a safe and cost-effective option for unplanned dialysis initiation in patients with late-presenting ESKD. To develop a successful USPD program, a strong infrastructure with clear pathways is essential. Coordination of care between nephrologists, surgeons or interventionalists, and hospital and PD center staff is imperative so that patient education, home visits, PD catheter placements, and urgent PD initiations are accomplished expeditiously. Implementation of urgent-start PD will help to increase PD use, reduce cost, and improve patient outcomes, and will be a step forward in fostering the goal set by the Advancing American Kidney Health initiative.
