Polymicrobial Peritonitis in Peritoneal Dialysis Patients in Australia: Predictors, Treatment, and Outcomes

Polymicrobial peritonitis can be treated successfully using antibiotics alone without catheter removal in most cases, particularly when only Gram-positive organisms are isolated. Isolation of Gram-negative bacteria (with or without Gram-positive bacteria) or fungi carries a worse prognosis and generally should be treated with early catheter removal and appropriate antimicrobial therapy.
