- Abstract
Objective To study the causes of the gastrointestinal endoscope failures and their impact on repair costs in order to provide recommendations and references for the implementation of the gastrointestinal endoscope troubleshooting and preventive maintenance. Methods The data of the gastrointestinal endoscopy failure repair in some hospital gastrointestinal endoscopy center from October 2020 to October 2021 were collected and statistically analyzed in terms of failure phenomenon, failure rate, repair site, repair grade, repair cost and repair parts replacement. SPSS 26.0 was used for statistical analysis. Results The gastrointestinal endoscopy failures involved in three aspects of water leakage (65.75%), image display (35.62%) and angle (24.66%). The overall failure rate of the endoscope was 0.16%, with the highest failure rate being 0.83% for the electronic duodenoscope. In terms of repair sites, most repairs occurred in the apex part (82.19% ), bending part (79.45%) and insertion part (78.08%). There were 86.30% of the repair grades of gastrointestinal endoscopes being C grade or below. Ultrasound endoscopy had the highest mean repair cost (¥ 83 256.00) for single time, followed by e-colonoscopy (¥ 33 824.32) and then e-gastroscopy (¥ 22 040.76). The frequently replaced parts mainly included rubber (9.83%), nozzle (9.09%) and clamp tube (8.91%). The replacement of spare parts such as the clamp tube, hose assembly, bending tube, switch, light-guiding tube, C-capand electrical interface significantly affect the maintenance cost of the gastrointestinal endoscope, and the increase in the replacement cost of the spare parts raised the overall maintenance cost. Conclusion The gastrointestinal endoscope failure repair analysis based on real world data is conducive to reducing the frequency of the gastrointestinal endoscope failures and repair costs and improving the efficiency of the gastrointestinal endoscope use.
