COVID-19 is generally believed to increase the risk of nosocomial infections, however, there is a gap in relevant researches on critically ill patients in cardiac care units (CCU).
This cross-sectional research was conducted in a tertiary-level non-epidemic hospital of Beijing, capital of China. The nosocomial infection rates of CCU were assessed prior to and during the of COVID-19 outbreak.
During the COVID-19 pandemic, the overall incidence of nosocomial infections decreased by 20.6-percent compared with the pre - pandemic period. Specifically, the total nosocomial infection rate during the COVID-19 pandemic ( = 0.04) decreased by 20.6%. Among various types of CCU-acquired nosocomial infections, the rates of pneumonia, urinary tract infection (UTI), bloodstream infection (BSI), gastrointestinal infection, and skin infection decreased by ranges from 4.7 to 100% during the COVID-19 pandemic. Meanwhile, a 1.5-percent increase in ventilator-associated events (VAEs) was observed during the COVID-19 pandemic.
During the COVID-19 pandemic, stricter implementation of infection control protocols appears to reduce nosocomial infections in CCU.
一般认为新型冠状病毒肺炎（COVID-19）会增加医院感染风险，然而，针对心脏重症监护病房（CCU）重症患者的相关研究存在空白。
本横断面研究在中国首都北京的一家三级非疫情医院开展。评估了COVID-19疫情暴发前及暴发期间CCU的医院感染率。
在COVID-19大流行期间，医院感染的总体发生率与大流行前相比下降了20.6%。具体而言，COVID-19大流行期间的医院感染总发生率（=0.04）下降了20.6%。在各类CCU获得性医院感染中，COVID-19大流行期间肺炎、尿路感染（UTI）、血流感染（BSI）、胃肠道感染和皮肤感染的发生率下降幅度在4.7%至100%之间。同时，在COVID-19大流行期间观察到呼吸机相关事件（VAE）增加了1.5%。
在COVID-19大流行期间，更严格地执行感染控制方案似乎可降低CCU的医院感染。
