Abstract:

Objective To identify potential risks in urine bacterial culturing and take measures to manage,control,optimize and assess high and medium risks,in order to offer accurate and timely reports. Methods Potential risks which affected the results of urine bacterial culturing in 5 aspects,including people,machine,material,method and process,in pre-examination,intra-examination and post-examination processes. The risks were graded according to severity,probability and detectivity. The unacceptable and measure-required risks should be managed. Results No unacceptable risk was observed in 10 determination procedures. Totally,3 measure-required risks were identified. The 3 measure-required risks were involved 5 key factors,non-standard operation by nurses and contaminative sterile containers in sample collection of pre-examination process,non-standard aseptic operation and failure of timely treatment in intra-examination process and wrong examination result interpretation. After taking relative measures,the contamination rate in urine bacterial culturing decreased by 9.3% from July-December 2015 to January-May 2015,and the positive rate increased by 9.5%. Conclusions Identification and management of potential risks in urine bacterial culturing are beneficial to improve the quality of urine bacterial culturing continuously.
