title: Frequency of puncture holes in peritoneal dialysis catheters related to the beta cap adapter.
abstract: Between November 2009 and September 2011, 12 patients (6 women, 6 men) undergoing continuous peritoneal dialysis (PD) or automated PD developed puncture-like holes in the PD catheter near the interface of the adapter with the superior aspect of the Silastic PD catheter The adapter is used to connect the PD catheter to the PD transfer set. Over the course of 23 months, the 12 patients presented to the PD unit with 19 separate instances of catheter holes, for an event rate of 0.23 holes per patient-year Data including socio-demographic information, PD modality, need for antibiotic treatment, event recurrence, infectious complications, and time from catheter placement were collected from patients whose catheters did and did not develop holes. We observed no differences between patients whose catheters developed holes and those whose catheters did not. The location of the individual holes suggested a relationship between the adapter and the catheter holes. The holes, which led to increased patient morbidity and costs, may be related to structural changes made in 2006 to the adapter.
