Objective To evaluate PDCA circle in training of cooperation quality in endoscopic nurse.Methods PDCA circle was applied to train endoscopic nurses.Knowledge of endoscopic nursing and techniques as well as operators' satisfaction with endoscopic examination were compared before and after PDCA circle training.Results Nursing scores increased from 92.40 to 96.00 with statistical significance (P ＜ 0.05).Performance scores increased from 93.03 to 98.13 (P ＜ 0.05).Operators' satisfaction increased from 81.3％ to 96.9％.Conclusion PDCA circle could improve not only endoscopic nursing but also the quality of endoscopic training.

To study the role of the activity in reducing the incidence of water leakage in digestive endoscopy, through the activity of the quality control circle (QCC), the reasons for water leakage and high maintenance cost are analyzed deeply. Then, the author formulated and implemented targeted measures to intervene in the non-standard aspects of daily management of endoscopy. Then targeted measures has been taken to improve the nonstandard daily management.Results demonstrate that the application of the quality control circle can significantly reduce the incidence of water leakage in the digestive endoscope and control the other faults caused by the leakage. This not only reduces the high maintenance cost of endoscopy, improves the utilization rate and turnover rate of endoscopy, but also fully explores personal potential, enhances team cohesion, and improves quality management awareness.
