目的

探讨PDCA循环法在提高髋关节超声图像质量中的应用价值。

方法

回顾抽查2017年7至12月在重庆市妇幼保健院行髋关节超声检查婴儿150例300髋,进行图像质控评分,以图像评分≥90分为甲类图像标准,针对甲类图像率不达标的情况成立持续质量改进(CQI)小组,采用PDCA循环法对髋关节图像质量进行改进,对2018年1月至6月在重庆市妇幼保健院行髋关节超声检查婴儿250例500髋进行图像评分,对PDCA循环前、后的甲类图像占比采用χ2检验进行分析。

结果

PDCA循环实施前髋关节甲类图像占比82%(246/300),实施后髋关节甲类图像占比96%(480/500),图像质量明显提高,差异有统计学意义(χ2=43.779,P<0.01),检查者对标准切面的掌握情况明显提高;PDCA循环前、后图像的扣分项目构成比变化反映了检查者规范存图意识的增强。

结论

PDCA循环法的运用有效提高了髋关节超声图像质量,值得在质控过程中推广。

Objective

To explore the application value of PDCA circulation method in improving the quality of ultrasonographic images of the infant hip.

Methods

Three hundred hip ultrasonic images of 150 infants screened at Chongqing Maternal and Child Health Hospital from July 2017 to December 2017 were evaluated, with an image quality score ≥ 90 regarded as grade A standard. A continuous quality improvement (CQI) group was set up for image quality assessment, and PDCA circulation method was utilized to improve the quality of ultrasonographic images of the infant hip. Then, 500 hip ultrasonic images of 250 infants screened at Chongqing Maternal and Child Health Hospital from January 2018 to June 2018 were evaluated. The proportions of grade A standard images before and after PDCA circulation were compared by chi-square test.

Results

82% (246/300) of images reached the standard before the PDCA circulation, and 96% (480/500) reached the standard after the PDCA circulation; the image quality was significantly improved after PDCA circulation (χ2=43.779, P<0.01). The sonographers' mastery of the standard section was improved obviously. The difference in the composition ratio of deduction items before and after PDCA circulation reflected the enhancement of the sonographers' consciousness of standard image storage.

Conclusion

The application of PDCA circulation effectively improves the quality of ultrasonic images of the infant hip, which is worthy of being popularized in the quality control process.
