Objective To explore the main failure components related to maintenance cost and downtime of gastrointestinal endoscopy.Methods The analytic hierarchy process (AHP) was used to process and analyze the maintenance data of gastrointestinal endoscopy in West China Hospital of Sichuan University from January 2010 to April 2019.Results The results involved 110 gastrointestinal endoscopy, 322 major repairs, 364 minor repairs, and a total of 1 651 failed components, in which the top three components were buttons (380 pieces, 23.02%), the insertion tubes (223 pieces, 13.51%), and lenses (179 pieces, 10.84%). The main failure components causing high maintenance cost and long downtime of major repairs were charge coupled devices (F=849.702, P<0.001; F=9.525, P=0.002) and light guides (F=8.190, P=0.005; F=6.384, P=0.012). The failure components affecting the maintenance cost of minor repair were lenses (F=25.464, P<0.001) and angle steel wires (F=5.652, P=0.018). The failure components prolonging the maintenance time of minor repair were lenses (F=10.384, P=0.001) and electrical interfaces (F=4.816, P=0.029).Conclusion Quantitative analysis of maintenance data is helpful to objectively analyze the main failure components of maintenance cost and downtime.
