Hospital infection control in intensive care unit: retrospective study Controle de infecção hospitalar em unidade de terapia intensiva: estudo retrospectivo

This study aimed at verifying the occurrence of isolated microorganisms of hospitalized patients during the stages of implantation of the Hospital Infection Control Commission (HICC) in an Intensive Care Unit at a private hospital in the city of Toledo, Paraná. It is about a retrospective study, during the period of February/ 2007 to March/ 2008. Of the total internments, 37 patients presented positive cultures and Pseudomonas aeruginosa was the most isolated microorganism, with 30.77% incidence, followed by Staphylococcus epidermidis, 23.08%, followed by other seven microorganisms with inferior incidences.This study aimed at verifying the occurrence of isolated microorganisms of hospitalized patients during the stages of implantation of the Hospital Infection Control Commission (HICC) in an Intensive Care Unit at a private hospital in the city of Toledo, Paraná.

In the second phase, during the beginning of the activities, 10 patients presented infection, with the growth of Pseudomonas aeruginosa, 30%, Klebsiella sp., 15%, Staphylococcus aureus, Klebsiella pneumoniae, Staphylococcus epidermidis, Enterobacter cloacae, 10%, and Streptococcus hemolytic gamma, Escherichia coli, and Enterobacter sp., 5%. With the CCIH norms being actively used in the third phase of the data collection, it is possible to realize that this relation distances itself, resulting in five patients with infection, being Pseudomonas aeruginosa, 75% and Staphylococcus epidermidis and Streptococcus hemolytic beta, 12.5%. About one year after the beginning of the activities of the HICC, it is observed that in he fourth phase, six patients presented infection, with Pseudomonas aeruginosa,54.5% and Enterobacter aerogenes, 45.5%. The formation, the training, the commitment and collaborating awareness of the medical staff, associated with the daily use of the norms praised by the hospital Infection Control Commission, are essential tools to enable the satisfactory and meaningful result in the reduction of the cases of hospital infection, improving the quality of health assistance.
