E-ESPD, elective ESPD; ESPD, early-start PD; PD, peritoneal dialysis; U-ESPD, urgent ESPD.
Demographic characteristics and clinical data of incident dialysis patients undertaking U-ESPD and E-ESPD. U-ESPD patients were more likely to receive a PD catheter inserted using the modified Seldinger technique, were more likely to require a post-procedural inpatient admission, and experienced a longer hospital length of stay, when compared to their E-ESPD counterparts.
