摘要 目的探讨品管圈在肝声触诊弹性成像(STE)图像标准化改进中的应用效果。方法浙江省宁波市鄞州区第二医院超声科成立品管圈小组,于2021年7月至12月开展以“提高肝STE图像达标率”为主题的品管圈活动。随机抽取2020年11月至2021年6月在本科室行肝STE检查的100例患者共500张STE图像进行解读,通过标准化指标对图像进行评分,并计算图像达标率。绘制鱼骨图、柏拉图分析造成图像不达标的原因,然后拟定对策、确定标准化等对图像质量进行持续改进。随机抽取品管圈实施后(2021年8月至12月)完成肝STE检查的100例患者共500张图像进行评分,计算图像达标率、目标达标率和进步率,采用χ^(2)检验比较品管圈活动前后肝STE图像达标率的差异。最后确认效果及标准化持续实施。结果实施品管圈后,肝STE图像质量明显提高,图像达标率由实施前的64.6%(323/500)提高到实施后的87.4%(437/500),目标达标率为110.7%,进步率为35.3%,实施前后图像达标率比较差异具有统计学意义(χ^(2)=71.25,P<0.001)。结论品管圈活动通过团队协作促进肝STE检查标准化,有效提高了图像的达标率。 Objective To explore the application value of quality control circle(QCC)in continuous quality improvement of liver sound touch elastography(STE).Methods The QCC group was established,and the theme of the activity was determined to be"improving the image quality control of liver STE"from July 2021 to December 2021.First of all,500 images of 100 patients who underwent liver STE examination at Department of Ultrasound,Ningbo Yinzhou Second Hospital from November 2020 to June 2021 were randomly selected.The images were scored by standardization,and the rate of reaching the standard was calculated.Fishbone diagram and Pareto diagram were plotted to analyze the possible causes of substandard image,and then formulate countermeasures and determine standardization to continuously improve the image quality.Subsequently,500 liver STE images of 100 patients who underwent examination from August 2021 to December 2021 were evaluated.The rates of reaching the standard before and after the implementation of QCC were compared by the chi-square test.Finally,the effect and standardization of continuous implementation were confirmed.Results After the implementation of QCC,the image quality of liver STE was significantly improved:64.6%(323/500)of images reached the standard before the QCC,and 87.4%(437/500)reached the standard after the QCC;the rates of reaching the standard differed significantly between before and after the implementation of QCC(χ^(2)=71.25,P<0.001).The target compliance rate was 110.7%,and the progress rate was 35.3%.Conclusion QCC activities can help standardize the operation process through team cooperation,and effectively improve the quality of liver STE images.
