目的：探讨品管圈活动提升眼科带螺母器械清洗质量的效果。方法：中山大学中山眼科中心珠江新城院区自2020年8月1日到2020年9月3 0日消毒供应中心处理的眼科带螺母器械(以量规为例)共2 076件，8月31日前为对照组，按常规清洗流程处理；9月1日后为实验组，成立品管圈小组，针对器械结构制定相应清洗流程。结果：实验组的清洗合格率为98.7%，对照组的清洗合格率为93.4%，差异有统计学意义(P<0.01)。结论：实施品管圈活动可提升眼科带螺母器械的清洗质量。

Objective: To explore the effect of quality control circle activity on improving the cleaning quality of ophthalmic equipment with nuts. Methods: The object of the study was 2 076 pieces of ophthalmic equipment with nuts (taking gauge as an example) used from August 1, 2020 to September 30, 2020 in the central sterile supply department of the Zhongshan Ophthalmic Center of Sun Yat-sen University in Zhujiang New Town. The equipment used before August 31 was set as the control group and was dealt with common cleaning process. The equipment used after September 1 was set as experimental group and the quality control circle group was set up to develop corresponding cleaning procedures for the instrument structure. Results: The qualified rate of cleaning in the experimental group was 98.7%, and that in the control group was 93.4%. The difference was statistically significant (P<0.01). Conclusion: Quality control circle activity can improve the cleaning quality of ophthalmic equipment with nuts.
