Purpose:The purpose of this study was to identify the risk factors for a nosocomial urinary tract infection in intensive care units with a foley catheterization which showed a positive urine culture.
Methods:Three-hundred eighty-seven patients were included in the study. A retrospective review of the electrical medical record system¡¯s databases and medical record sheets in hospitalized patients from January 2003 to December 2003 was used. The collected data was analyzed by descriptive statistics, t-test, chi-square test and logistic regression analysis.
Results:The frequency of the participants¡¯ nosocomial urinary tract infection was 72.9%. Significant risk factors for a nosocomial urinary tract infection were ¡®age¡¯, ¡®place of catheter insertion¡¯, ¡®frequency of catheter change¡¯, and ¡®duration of catheterization¡¯. These variables explained 18.4% of variance in the experience of nosocomial urinary tract infection in intensive care units with foley catheterization.
Conclusion:Medical personnel can decrease the incidence of a nosocomial urinary tract infection by recognizing and paying attention to the duration of catheterization, frequency of catheter change, and place of catheter insertion. As a result, specific and scrupulous strategies should be developed to reflect these factors for decreasing nosocomial urinary tract infections.
