To identify the factors affecting the conformity rate of ultrasonic diagnosis.

The echelon of personnel in ultrasound department and ultrasonic quality control indexes uploaded by Anhui provincial sentinel hospitals (including secondary and tertiary hospitals), as well as the special training carried out by Anhui provincial ultrasonic quality control center during 2020-2021 were analyzed.

Compared with the figures in 2020, the number of senior doctors in secondary and tertiary hospitals in Anhui Province has increased significantly in 2021 [194 (20.00%) vs 128(15.67%); 336 (27.18%) vs 249 (23.71%)]. From 2020 to 2021, the coincidence rate of ultrasonic diagnosis in hospitals in Anhui province showed an increasing trend, especially in tertiary hospitals [86.65% (1586/1830) vs 83.01% (1519/1830)]. In 2020 and 2021, the qualification rate of ultrasound report writing in both secondary and tertiary sentinel hospitals in Anhui Province exceeded 90%. Compared with the rate in 2020, the qualification rate of ultrasound report writing in secondary sentinel hospitals in Anhui Province increased significantly in 2021 [99.40% (2326/2340) vs 93.93% (2198/2340)]. Compared with the rate in 2020, the qualified rate of ultrasonic instrument quality detection in secondary sentinel hospitals in Anhui Province increased significantly in 2021 [96.39% (321/333) vs 93.09% (310/333)]. The number of quality control training times in Anhui Province in 2021 increased significantly compared with that in 2020 (53 vs 22). From 2020 to 2021, the utilization rate of BI-RADS classification and the accuracy of ultrasound diagnosis of breast masses in secondary hospitals increased from 69.15% (1618/2340) to 82.44% (1929/2340) and from 71.67% (1677/2340) to 75.30% (1762/2340), respectively. The utilization rate of BI-RADS classification and the accuracy of ultrasound diagnosis of breast masses in tertiary hospitals increased from 89.62% (1640/1830) to 93.88% (1718/1830) and from 78.14% (1430/1830) to 81.58% (1493/1830), respectively.

The conformity rate of ultrasonic diagnosis is affected by many factors. Improving the qualified rate of ultrasonic report writing, the professional level of ultrasound physicians through special training, and the standardized diagnosis of breast masses is important for improving the conformity rate of ultrasonic diagnosis.
