Objective  To explore the application effect of standardized quality control concept in the quality control of ultrasound department.

  Methods  A standardized quality control management system was established, based on the quality control concepts of "medical quality first, medical safety first", "PDCA continuous improvement", and "full-process quality control and all-department participation". We compared average outpatient and inpatient ultrasound appointment times from January 2019 to June 2019 and January 2021 to June 2021, patient satisfaction and clinical satisfaction data of ultrasound department from January 2019 to June 2019 and October 2019 to March 2020 before and after the establishment of the standardized quality control management system, and the annual ultrasound diagnosis consistent rate from 2020 to 2021 after the establishment of the standardized quality control management system.

  Results  After the establishment of the standardized quality control management system, the mean outpatient ultrasound appointment time and inpatient ultrasound appointment time was shortened(5.00±0.89)days vs. (13.33±2.81)days, P=0.009; (1.33±0.52)days vs. (3.50±0.55)days, P=0.448. The scores of patient and clinical satisfaction were significantly higher than those before implementation(89.56±0.95)points vs. (86.91±3.12)points, (87.28±2.04)points vs. (82.95±4.59)points, and all differences were statistically significant (P < 0.05). The consistent rate of ultrasound diagnosis in 2021 (94.7%) was significantly higher than that in 2020 (93.5%)(P < 0.05).

  Conclusion  The establishment of the standardized quality control system has shortened the average appointment time for outpatient and inpatient ultrasound examinations, improved the patient and clinical satisfaction and the average ultrasound diagnostic compliance rate, and effectively improved the quality of medical services and quality control, thus showing good application effects on ultrasound quality control.
