Multi-resistant Gram-negative Bacteria Cause Infection

This is a prospective, observational, multicenter study whose main objective is to develop a predictive model of mortality in critically ill patients colonized by multidrug-resistant Gram-negative bacteria (MDR-GNB). Secondary objectives include: determining the characteristics of patients colonized by MRGB who require admission or acquire colonization during their stay in an intensive care unit (ICU); studying the infectious complications they develop, their etiology, clinical impact, and prognosis.
