Objective To explore the application value of PDCA cycle method in reducing errors in ultrasonic measurement reporting. Methods From October 2017 to September 2018

the number of cases reporting errors of measurement in the ultrasound department of the Third Affiliated Hospital of Chongqing Medical University was retrospectively collected on a quarterly basis. The continuous quality improvement team of the department (CQI) used PDCA cycle method to improve the reports due to measurement error reporting every quarter. Chi-square test was used to analyze the difference between the number of measurement error cases reported before and after PDCA cycle management. Results The proportion of measurement error report before PDCA cycle management was 0.22‰ (6/27059)

and the proportion of measurement error report after multiple PDCA cycle management was 0.03‰ (1/36378). The number of measurement error report cases was significantly reduced

and the difference was statistically significant (P=0.047 < 0.05). Conclusion PDCA cycle method can effectively reduce the incidence of measurement report errors and ensure the quality and safety of medical treatment.
