Abstract:
OBJECTIVE To explore the effect of tracking methodology on investigation of contamination incidents of bronchoalveolar lavage fluid(BALF)specimens from the children.METHODS The onsite tracking was carried out for the contamination incidents of BALF specimens of the children through the tracking methodology,the quality control processes of cleaning and disinfection of bronchofiberscopes and the tracking routes were determined.The quality control process of cleaning and disinfection of bronchofiberscopes were evaluated,the existing risks were found out,and the specific improvement measures were formulated.RESULTS The onsite tracking was carried out for the incident of carbapenem-resistant Klebsiella pneumoniae(CRKP)that was caused by the contamination of 12 BALF specimens from pediatrics department wards before and after Nov.1,2021.No.2180014C bronchofiber-scope without biological surveillance was determined as the high-risk point of contamination of BALF specimens,the monitoring procedure of cleaning and disinfection of the bronchofiberscopes was revised.The BALF specimens that were submitted from Dec.1,2021 to Dec.31,2021 were tracked,and no CRKP was detected among the 23 submitted specimens.Totally 12 bronchofiberscope specimens were collected for biological surveillance,and the qualified rate was 100.00％.The treatment rooms of pediatrics department,hand disinfection effect of health care workers of cleaning and disinfection rooms and disinfection effect of object surfaces were monitored,and the quali-fied rate was increased from 98.39％to 100.00％.CONCLUSIONS The tracking methodology is an effective tool for quality management and can be used for evaluation of quality process of cleaning and disinfection of bronchofi-berscopes,which may find out the causes for adverse events in a timely manner and raise the medical safety.
