Targeted monitoring of healthcare-associated infection in intensive care unit in a tertiary first-class hospital,2019-2021
Objective To understand the healthcare-associated infection(HAI)and device-associated infection in the intensive care units(ICU),and provide scientific basis for HAI management.Methods HAI monitoring data of patients in ICU in a tertiary first-class hospital from January 2019 to December 2021 were collected and conducted statistical analysis.Results A total of 2 302 patients were monitored,and 120 patients(138 cases)had HAI.Inci-dence and cases incidence of HAI were 5.21％and 5.99％respectively.There were no statistically significant differences in incidence of HAI and case incidence of HAI in 2019-2021(all P＞0.05).The main HAI site was lower respiratory tract(n=96 cases,69.57％),followed by the urinary tract(n=28 cases,20.29％)and blood-stream(n=6 cases,4.35％).A total of 125 strains of pathogens were isolated,with Gram-negative bacteria being the main strain,accounting for 74.40％.The incidence of central catheter-related bloodstream infection(CRBSI),catheter-associated urinary tract infection(CAUTI),and ventilator-associated pneumonia(VAP)were 0.34‰,1.47‰,and 8.65‰,respectively.Over the past three years,the incidence of device-associated infection decreased and VAP decreased significantly(both P＜0.05).Among healthcare-associated non-device-associated infection,the proportion of pulmonary infection increased from 23.53％to 46.00％,with a statistically significant difference(P＜0.05).Conclusion Three consecutive years of targeted monitoring showed that the incidence of catheter-associated infection decreased,but the incidence of non-device-associated infection increased.HAI management should strength the monitoring of the implementation of HAI prevention and control measures for non-mechanically ventilated pa-tients,so as to reduce the overall incidence of HAI in ICU.
