ObjectiveTo investigate the effect of quality control circle (QCC) activity in reducing the temporarily stopping rate of day surgery.MethodsThe QCC activity was carried out from December 2018 to October 2019. By determining the theme of the activity and drawing up the plan, a retrospective analysis of pre-hospital day surgery stoppage status and reasons was performed based on 2 696 patients who had reserved surgery in the day surgery center from December 2018 to February 2019. Based on the data, the goal was determined, and measures were developed and confirmed from May to August 2019. Then the measures were standardized and implemented continuously from September to October 2019. The rate of surgical cessation before the implementation of the measures (from December 2018 to February 2019) was compared with that after the implementation of the measures (from September to October 2019).ResultsAfter the QCC activity, the temporarily stopping rate decreased from 2.89% to 1.34%, and the difference was statistically significant (P<0.001).ConclusionThe QCC activity can effectively reduce the temporarily stopping rate of day surgery, and lay the foundation for continuously promoting the optimization of day surgery resources and quality improvement.
