To evaluate the application value of PDCA cycle in the construction of superficial organ ultrasound subspecialty.

Fifty ultrasound images of thyroid and breast nodules and 50 issued reports were randomly selected at the Department of Ultrasound Medicine of the First Affiliated Hospital of Nanchang University from July to December 2017. They were reviewed and scored (≥85 were classified as class A cases, 80-85 as class B cases, and <80 as class C cases). In June 2018, PDCA cycle was adopted to improve the medical quality of thyroid and breast nodule ultrasound image storage and issued reports. Fifty thyroid and breast nodule ultrasound images and 50 issued reports were randomly selected from January to June 2019, reviewed and scored. Independent sample t-test was used to compare the difference in the score between the two groups.

The average score of ultrasound images of thyroid and breast nodules and issued reports after the implementation of PDCA cycle was significantly higher than that before the implementation of PDCA cycle [(90.87±4.11) vs (75.84±8.69), t=15.635, P<0.001], and the mean difference was 15.030.

The implementation of PDCA cycle can significantly improve the quality of storage of images of thyroid and breast nodules and report writing, which is helpful to improve the quality of superficial organ ultrasound. PDCA cycle plays an important role in the construction of superficial organ ultrasound subspecialty.
