Hospital bacterial resistance to multiple antibiotics is a great concern worldwide. This study objective was to know the multidrug-resistantance (MDR) agents, clinical materials, origin, trends, and to correlate them with the bacterial sensitivity and antimicrobial consumption. A total of 53,316 nosocomial bacteria were assessed in a tertiary hospital during the period from 1999 to 2008. MDR was defined for gram negative bacteria (GNB) when it presented resistance to two or more classes/groups of antibiotics. GNB were predominant (66.1%). GNB MDR had a global increase of 3.7 times in the end of the period. Acinetobacter baumannii was the most prevalent (36.2%). The most frequent materials were urinary and respiratory. A significant increase occurred during the period of 4.8 and 14.6 times of the A. baumannii and K. pneumoniae, respectively. Sixty-seven percent of GNB MDR was from the Intensive Care Units. A. baumannii resistance to carbapenemics increased from 7.4% to 57.5% during the period, concomitant to the consumption increase. The resistance of K. pneumoniae to the cephalosporins had a high increase during the decade. P. aeruginosa decreased in these last two years with a recovery of the sensitivity.
