e-STEPS: Endotoxin-Associated Sterile Peritonitis Observational Study

This observational retrospective healthcare medical record review study is to evaluate and differentiate the clinical characteristics and outcomes in peritoneal dialysis (PD) patients with either endotoxin-associated sterile peritonitis (e-SP), bacterial peritonitis (BP) or no peritonitis (NoP) over a 12-15 month period from dialysis clinics in The Netherlands, Germany, Hungary, Portugal, and the United Kingdom (UK). The primary study objectives are to: * Describe changes in the peritoneal membrane function and clinical outcomes over time between e-SP, BP and NoP PD patients. * Describe and differentiate clinical characteristics during the acute clinical presentation of e-SP and BP. The secondary study objective is to: \- Generate a dataset that will facilitate post hoc exploratory hypothesis-generation related to clinical and resource utilisation (RU) outcomes in association with e-SP.
