Research on failure mode and effect analysis in endoscope disinfection management / 中国实用护理杂志

ABSTRACT

Objective To identify and investigate the cause of the unacceptable bacteria level inside the lumen of fiberendoscope during monitoring so as to increase the pass rate of its cleaning and disinfection. Methods A failure mode effect analysis of the cause was done and the workflow was thereafter improved. Meanwhile, pre and post bacteriological monitor was applied to the fiberendoscope lumen samples. Results The number of scrubbing times while manual cleaning affected the monitoring results. The scrubbing times was amended and the pass rate increased from 84.15% to 98.65%. The results were significantly different The failure mode risk index of endoscope cleaning and disinfection was calculated, and the highest two items were The number of scrubbing times the operators execute RPN=640, the method of lumen cleaning RPN=480. These were the key factors of qualification of monitoring. Conclusions After the amendment, no less than 5 times' scrubbing was required and the bacteriological monitoring method was used to analyze the effects,thereafter the pass rate of lumen bacteria monitoring can be increased significantly.
