Abstract
Objective To identify the occurrence and microorganism profile of device-associated healthcare-associa-ted infections (DA-HAIs)in the intensive care unit (ICU)of a university hospital in China.Methods From Janua-ry 1 to November 30,2015,patients admitted to the ICU of a university hospital in China for more than 48 hours were performed prospective descriptive study. DA-HAIs were defined according to the criteria of the Centers for Disease Control and Prevention (CDC)of U.S.,descriptive statistical analysis was performed.Results Of 254 pa-tients admitted to ICU,the overall incidence of DA-HAIs was 15.35% ,with 10.23 cases of DA-HAIs per 1 000 ICU-days;the incidence of ventilator-associated pneumonia (VAP ),catheter-associated urinary tract infection (CAUTI),and central line-associated bloodstream infection (CLABSI)were 7.05 per 1 000 ventilator-days,4.91 per 1 000 urinary catheter-days,and 3.22 per 1 000 central line-days,respectively. The main infection site was lower respiratory tract,accounting for 48. 27% ,followed by bloodstream system (27. 59% ),urinary tract (22.99% ),and gastrointestinal tract(1.15% ). The major isolated microorganism was Acinetobacterbaumannii (21 .52% ).Conclusion The surveillance system can identify the epidemiological status of DA-HAIs and make effec-tive control measures to ensure the healthcare safety.关键词
