Distribution of pathogenic bacteria causing hospital-acquired urinary tract infection and logisticregression analysis of risk factors

OBJECTIVE To analyze the risk factors and pathogenic distribution in patients who had hospital-acquired urinary tract infections,and to develop program for prevention and control of hospital infection.METHODS The cases with or without urinary tract infections hospitalized between Aug 2009 and Aug 2010 were retrospectively studied.The pathogen distribution and the risk factors for hospital-acquired urinary tract infections were analyzed by logistic regression.RESULTS The results revealed that the female aged≥60 years,indwelling catheterization,and indwelling time 20d,with the primary diseases and the hospitalization35d were significantly correlated with hospital-acquired urinary tract infections(P0.05).The most common pathogens were fungi,accounting for 40.85%,followed by Gram-negative bacteria(34.15%) and Gram-positive bacteria(25.00%).CONCLUSION Better understand the risk factors for urinary tract infection has great significance for the effective prevention of hospital-acquired urinary tract infection.
