This study aims to define the prevalence of bacterial pathogens in patients admitted to the Intensive Care Unit of a reference hospital in Teresina-PI. This is a cross-sectional study with descriptive and quantitative approach, performed in the Intensive Care Units of a hospital in the capital city of Piauí. Data collection was performed by consulting the files of the Hospital Infection Control Commission. We analyzed 578 records for the year 2012, the data were tabulated using Microsoft Office Excel. The research was approved by the Research Ethics Committee with the protocol number 260.386/13. The prevalence of patients undergoing oncologic procedures in the Intensive Care Unit was observed. Respiratory infections were the most frequent (37%), followed by urinary (30%) and blood (20%) infections. Pseudomonas Aeruginosa was identified as the most prevalent bacterium in the microbiological test cultures of patients admitted to the Intensive Care Unit with a percentage of 31% (n=112), Klebsiella Pneumoniae 21% (n=75), Acinetobacter spp 13% (n=46) and Escherichia coli 11% (n=41), other microorganisms demonstrated high infection incidence such as Klebsiella Pneumoniae having a greater prominence due to the production of ESBL, in which its profile of sensitivity and resistance to antibiotics was analyzed. Respiratory infections showed a high predominance, in isolated cases associated to hospital beds, which was preeminent in cardiac Intensive Care Unit, as well as, in infectious and general cases.

Keywords: Epidemiology, Prevalence, Hospital Infection, Intensive Care Units.
