Background
Use of peritoneal dialysis (PD) has expanded in recent years because of policies of the U.S. Government and incentives from the Centers for Medicare & Medicaid Services (CMS). In June 2023, CMS added a Peritonitis Infections module in the EQRS. We explored peritonitis outcomes of hospitalization, loss of the PD catheter, and suspension of PD during peritonitis episodes.
Methods
We used new ESRD Quality Reporting system data from July 1, 2024 to Feb 28, 2025. Outcomes following a peritonitis episode as repoted in EQRS were hospitalization, loss of the PD catheter, and suspension of PD. We examined associations of age, sex, and race/ethnicity with these outcomes using logistic regression models.
Results
Nearly a quarter (23.1%) of reported peritonitis episodes resulted in hospitalization, and nearly 1 in 7 resulted in loss of the PD catheter (13.5%) and suspension of PD (13.3%). Women were more likely than men to experience hospitalization following a diagnosis of peritonitis (odds ratio [OR], 1.29; 95% confidence intervals [CIs], 1.15-1.45), as were younger people (OR 1.31, 95% CIs 1.13-1.52 for those aged 18-44 years versus those aged 45-64 years). Hispanic, relative to White, individuals also had an increased risk (OR 1.23, 95% CIs 1.05-1.44). There were no significant differences by demographic characteristics for the other outcomes.
Conclusion
Approximately a quarter of reported peritonitis episodes result in hospitalization. Nearly 1 in 7 resulted in the need to remove the catheter, and almost all of those needed to discontinue PD. Hospitalization after peritonitis diagnosis varies by age, sex and race/ethnicity. These outcomes should be tracked as use of PD expands.
