Key Points

To identify risk factors associated with multidrug-resistant organisms in peritonitis and their effects on outcomes.
Multicenter prospective observational design
Analysis of peritonitis episodes from the PDOPPS-Korea cohort
Evaluation of independent risk factors for MDRO infections
14.0% of peritonitis episodes caused by multidrug-resistant organisms.
Independent risk factors for MDRO-peritonitis included prior hospitalization, diabetes, and recurrent episodes.
Causative organism characteristics had a more significant impact on treatment outcomes than MDRO status.

Abstract

Nearly one in seven peritonitis episodes (14.0%) was caused by MDROs. Prior hospitalization, diabetes mellitus, and recurrent peritonitis were independent risk factors for MDRO-peritonitis. Regarding peritonitis cure, characteristics of causative organisms tended to have a greater impact than did MDRO status itself.
