Peritoneal Dialysis (PD) associated peritonitis is the leading cause of transfer to hemodialysis (HD) in the US. No formal mechanism or surveillance system exists for nationwide peritonitis reporting. Our primary aim was to develop a uniform widescale peritonitis reporting mechanism and evaluate its implementation via a one-year pilot study.


Following literature review, stakeholder consultation, and ISPD guidelines review, a web-based peritonitis tracker tool (OPPUS-Link) was developed. Pilot sites for one-year data collection were selected based on geography and reported peritonitis rates, including 3 medium-large dialysis organizations. We provided formal training, central data review, and adjudication of all peritonitis episodes and outcomes.


Initial data for 31/64 participating facilities includes 86 peritonitis episodes (rate of 0.26 episodes/year [326 patient years of follow-up]). PD catheter removal and hospitalization occurred in 14% and 41% of episodes respectively (see table). Ongoing challenges include high rates of culture-negative peritonitis (24% overall) and data retrieval for peritonitis episodes occurring during hospitalization.


Standardized, uniform peritonitis reporting is feasible, a first step in national PD-peritonitis surveillance, allowing for benchmarking, outbreak identification, and quality improvement initiative implementation. Further data validation is necessary and integrating routine peritonitis reporting in electronic health records with an overall goal of peritonitis reduction and improved outcomes for PD patients.
