Abstract:
OBJECTIVE To investigate and control a suspected outbreak of hospital-associated Elizabethkingia a-nopheles infection in respiratory intensive care unit(RICU),and provide scientific basis for effective prevention and control of hospital-associated E.anophelis infection.METHODS The tracking source analysis was performed for 9 identified cases who were detected with E.anophelis through epidemiological survey,environmental hy-giene monitoring and endoscopic cavity visualization system,the surroundings that they contacted and the instru-ments they were treated with were investigated.The targeted prevention and control measures were implemented.RESULTS A total of 55 samples were collected from the surrounding environment and shared instru-ments of 9 patients detected with E.anophelis.Totally 6 samples were detected positive for the environmental ob-ject surfaces of 3 patients,and 15 positive samples were identified as the same source by homology analysis.Two faulty bronchoscopes were found through the visualization system of lumen instruments.CONCLUSIONS There are multiple pathways of cross-contamination of bronchoscope and person-to person transmission of E.anophelis in RICU.Strengthening the management of cleaning and disinfection of bronchoscope,increasing the frequency of cleaning and disinfection of RICU environmental surfaces and improving the compliance of hand hy-giene of medical staff are important measures to control the outbreak of hospital-associated infection.
