Targeted surveillance results of healthcare-associated infection in the liver transplantation intensive care unit from 2018 to 2022
Objective To analyze the characteristics of healthcare-associated infection(HAI)in patients in liver transplantation intensive care unit(ICU),and provide basis for the effective prevention and control of liver post-transplantation infection.Methods Targeted surveillance data of HAI in liver transplantation ICU from 2018 to 2022 were analyzed retrospectively.Incidence,incidence trend,infection site,pathogens and drug resistance were analyzed.Results A total of 3 762 liver transplantation patients were surveilled,106 patients developed 133 cases of HAI,with an incidence of 2.82%and a case incidence of 3.54%.There was no significant difference among the years(P=0.473).Infection mainly occurred within 2 weeks after admission to ICU,accounting for 85.85%.The main infection sites included blood system(26.32%),respiratory system(22.56%),and surgical site(19.55%).The average utilization rates of central veinous catheterization,urethral catheterization,and ventilator were 85.77%,70.58%,and 40.83%,respectively.The incidences of central line-associated bloodstream infection(CLABSI),catheter-associated urinary tract infection(CAUTI),and ventilator-associated pneumonia(VAP)were 0.54‰,0.33‰,and 1.84‰,respectively.A total of 131 strains of pathogens were detected,of which Gram-negative bac-teria accounted for 38.17%and Gram-positive bacteria accounted for 29.77%.The top three pathogens were Kleb-siella pneumoniae(15.27%),Enterococcus faecium(11.45%),and Acinetobacter baumannii(9.16%).Conclusion Effective prevention and control measures should be taken based on the characteristics of HAI in the liver transplan-tation ICU,so as to curb bacterial resistance and reduce liver post-transplantation HAI.
