RESUMO

Objective To understand healthcare-associated urinary tract infection (HA-UTI)and pathogens causing HA-UTI in intensive care unit (ICU)patients,so as to provide scientific basis for the prevention and control of HA-UTI. Methods Targeted surveillance data about HA-UTI in 32 hospitals in 2013 were analyzed.Results A total of 23 680 ICU patients were monitored,157 cases of HA-UTI occurred,HA-UTI rate was 0.66%;the usage rate of urinary tract cathe-ter was 80.83%,catheter-associated UTI was 1.25‰.A total of 162 pathogenic strains were detected,the percentage of fungi,gram-negative bacteria,and gram-positive bacteria was 40.74% (n=66);31.48 % (n=51),and 27.78% (n=45)respectively.Conclusion The main pathogens causing HAI-URI are fungi,comprehensive intervention measures should be taken to control HA-UTI in ICU patients.

RESUMO

Objective To understand the status of intensive care unit-acquired lower respiratory tract infection (ICU-LRTI),and the distribution characteristics of pathogens,so as to provide the basis for taking preventive and control meas-ures,and scientific diagnosis and treatment for patients.Methods Targeted monitoring data on healthcare-associated infec-tion (HAI)in ICUs of 32 hospitals in a province in 2013 were investigated retrospectively.Results The incidence of ICU-LRTI was 5.79%,ventilator usage rate was 31.25%,incidence of ventilator-associated pneumonia(VAP)was 26.93‰;There was no linear correlation between ventilator usage rate and incidence of VAP(r=0.160,P=0.380).A total of 1 593 pathogens causing LRTI were detected,the major were gram-negative bacteria (75.77 %,n=1 207),followed by gram-positive bacteria(18.21%,n=290),fungi(5.90%,n=94),Mycoplasma pneumonia and other pathogens(0.12 %,n= 1 for each).The top five detected pathogens causing LRTI were Acinetobacter baumannii ,Pseudomonas aeruginosa ,Staph-ylococcus aureus ,Klebsiella pneumoniae and Escherichia coli ,accounting for 25.49%,15.26%,14.63%,13.37% and 5.09% respectively.Conclusion Targeted monitoring on ICU is helpful for realizing healthcare-associated LRTI, each hospital should conduct targeted monitor to find out the causes of HAI,as well as improve the awareness of VAP among ICU health care workers.
