To investigate the basic situation of thyroid ultrasound examination and the use of TIRADS classification in hospitals in Haidian District, and explore the feasibility of promoting the use of the Chinese version of TIRADS (C-TIRADS) to improve the ultrasound diagnosis quality.

An online questionnaire was administered and collected through a WeChat application, and the subjects of the survey were ultrasound departments of hospitals in Haidian District. The questionnaire mainly included three parts: general information of thyroid ultrasound examination, the use of the TIRADS classification, and the report positive rate and diagnostic accordance rate.

A total of 105 questionnaires were collected, of which 91 were valid after removing invalid ones. Seventy (76.9%) hospitals routinely performed thyroid ultrasound examinations, including 12 tertiary and 12 secondary hospitals, as well as 46 primary hospitals. Approximately 12.9% (9/70) of them, mainly tertiary hospitals, performed ultrasound-guided thyroid intervention techniques (including biopsy). Only one secondary hospital conducted these procedures, and none of primary hospitals performed. A total of 35 hospitals (50.0%) used TIRADS classification systems in their ultrasound reports, of which 22 (62.9%) used the C-TIRADS, 11 (31.4%) used the ACR-TIRADS, and 2 (5.7%) used the ATA guidelines. The average report positive rate of thyroid ultrasound was 73.1% and the average diagnostic accordance rate was 85.3%.

Further improvement in the coverage of C-TIRADS usage in hospitals in Haidian District is needed. The Ultrasound Medical Quality Control and Improvement Center of Haidian District will continue to strengthen the quality control of thyroid ultrasonography, promote the use of C-TIRADS in the diagnosis of thyroid nodules, and improve the diagnostic accordance rate.
