Controversies in nosocomial peritonitis.

This document focuses on the different aspects to be considered in order to improve the management of nosocomial peritonitis, particularly the changes in the epidemiology of causative microorganisms and the increasing emergence of pathogens resistant to commonly used antimicrobials. To facilitate their identification and treatment, the latest advances in microbiological diagnosis and evidence on the efficacy of new antimicrobial alternatives against resistant microorganisms are presented. All these factors, together with measures aimed at reducing treatment duration, also addressed in this document, will be analyzed in depth in a second paper to be published shortly.
