BACKGROUND AND OBJECTIVES: Nosocomial infection represents a challenge in clinical practice involving hospitalized patients, as they considerably extend the hospitalization period and morbidity and mortality rates and, at the same time, increase hospital costs. Given their clinical conditions, which require invasive procedures and antimicrobial treatment, hospitalized patients, especially at the Intensive Care Unit, are particularly susceptible to hospital infection. This study aimed to evaluate the occurrence of multiresistant bacteria in patients hospitalized at the Intensive Care Unit of a Brazilian emergency hospital. METHODS: Our retrospective study was approved by the Ethics Committee and considered the period between October 2003 and September 2004. A database was developed through variable coding and double entry, and Statistical Package for Social Sciences (SPSS) software, version 10.0, was used for statistical analysis. RESULTS: Multiresistant bacteria were identified in 68 patients, 47 (69.1%) of whom were men, with 55 years as the mean age. All patients were submitted to endotracheal intubation and central venipuncture. The most frequent bacteria were coagulase-negative Staphylococcus sp. (36.4%), followed by Staphylococcus aureus (19%). Cephalosporin was the most frequently used (21.4%) antimicrobial agent. CONCLUSIONS: Knowledge on infection occurrence provokes reflections on multiresistance, directs educative actions and favors interventions to prevent and control problem situations.

BACKGROUND AND OBJECTIVES: Care in the intensive care unit (ICU) is constantly challenged by infections related to invasive procedures, which result in increased morbidity and mortality, hospitalization term and costs. This study aimed to prospectively evaluate critical patients according to age, clinical conditions, hospitalization term, occurrence of hospital infection, topography of hospital infection, occurrence of microbial multi-resistance or not, use of invasive procedures and antimicrobial agents. METHODS: This is a prospective, observational, clinical research, carried out at an ICU between February and July 2006. The research subjects were critical patients hospitalized for more than 24 hours at the ICU, followed from admission until discharge, transference or death. RESULTS: The study group consisted of 71 patients with a mean age of 53.5 ± 18.75 years. Forty-seven of these patients (66.2%) acquired hospital infection. Twenty-nine infections (37.6%) occurred in the blood stream, 20 (26%) respiratory and 13 (16.9%) urinary. The most frequent multi-resistant strains were: 14 (10.85%) Pseudomonas aeruginosa, 4 (3.1%) coagulase-negative Staphylococcus sp and 4 (3.1%) Staphylococcus aureus. The most used antimicrobial agents were carbapenem (22.4%), glycopeptides (21.6%) and cephalosporin (21.6%). Twenty-nine (40.8%) of these patients died. CONCLUSIONS: Hospital infection is aggravated if associated to the increased resistance of the microorganisms to the antibiotics.
