    AbstractHealthcare-associated infections (HAIs) continue to be the most common adverse event affecting critically ill inpatients in intensive care units (ICUs). Limited data exist in the English literature on the epidemiology of HAIs in ICUs from China. The purpose of this prospective study was to understand the prevalence and trends of HAIs in the ICU to guide clinicians to take effective prevention and control measures. In total, 20 ICU beds in the hospital from January 2012 to December 2019 were selected for surveillance. HAI diagnosis and device-associated infection surveillance were based on the criteria set forth by the original Ministry of Health of the People's Republic of China. The full-time staff for HAI management monitored all patients who stayed in the ICU > 48 hours during the study period and calculated the device utilization ratio and device-associated infection rate. The rate of HAIs and the adjusted rate were 18.78 per 1000 patient-days and 5.17 per 1000 patient-days, respectively. The rates of ventilator-associated pneumonias, catheter-associated urinary tract infections, and central line-associated bloodstream infections were 22.68 per 1000 device-days, 2.40 per 1000 device-days, and 2.27 per 1000 device-days, respectively. A total of 731 pathogenic bacteria were detected in the patients with HAIs. Gram-negative and gram-positive bacteria accounted for 67.44% and 16.83%, respectively. Continuous target monitoring, regular analysis of high-risk factors, and timely intervention measures could effectively reduce HAIs in the ICU. Additionally, these findings could be used for developing new strategies to prevent and control HAIs in ICUs.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
