Abstract：Objective To set a series of measures to lower the maintenance rate and costs through analyzing the cases of endoscope
failure and its basic events. Methods Endoscope failure was set up as the top event. Then a fault tree was established to show the
logical relationship between basic events and the top event. We calculated the failure rate and importance to find out high incidence
events. Corresponding measures were made for the events. Results A total of 5 basic events of endoscope failure were discovered by
fault tree analysis. The endoscope failure rate reduced 42.4% by implements corresponding measures. Conclusion It was successful
that fault tree analysis has been used for endoscope failure analyzing. The implementation of the corresponding measures can
significantly improve the clinical management of endoscope, decrease the endoscope failure rate and increase the service efficiency.
