With the growing demand for breast screening in public health services and clinical care, ultrasound departments in China are facing tremendous challenges.
A cross-sectional nationwide survey was conducted in 5,460 departments providing ultrasound diagnoses in mainland China from 2020 to 2021. The survey included general information about the ultrasound department, the characteristics of sonologists, the use of Breast Imaging Reporting and Data System (BI-RADS) templates, and the diagnostic accuracy rate of breast cancer ultrasound.
There were on average 2.25 sonologists per 10,000 patients in mainland China per year. The average utilization rate of BI-RADS in Chinese hospitals was 87.02%. The GDP per capita of the province ( = 0.008), whether the hospital was specialized ( = 0.002) or a Tier 3 facility ( < 0.001), the percentage of doctors with master's and doctoral degrees ( < 0.001) and doctors ≤35 years ( = 0.005) were significantly and independently associated with the utilization rate of BI-RADS. The average diagnostic accuracy rate of breast cancer ultrasound in Chinese hospitals was 73.64%, and we observed significant positive associations between GDP per capita ( = 0.02), BI-RADS utilization rate ( = 0.019), and breast cancer ultrasound diagnostic accuracy.
The utilization of BI-RADS templates effectively improved the diagnostic accuracy of ultrasound. Moreover, the survey summarized the current situation of departments and sonologists providing breast ultrasound diagnosis in mainland China, which helped monitor the development of the discipline and provide information for administrators to meet the growing demand.

随着公共卫生服务和临床医疗中乳腺筛查需求的不断增加，中国超声科室面临巨大挑战。
2020年至2021年，对中国大陆5460个提供超声诊断的科室进行了横断面全国性调查。调查内容包括超声科室的一般信息、超声医师的特征、乳腺影像报告和数据系统（BI-RADS）模板的使用情况以及乳腺癌超声诊断准确率。
中国大陆每年每10000名患者平均有2.25名超声医师。中国医院BI-RADS的平均使用率为87.02%。省份人均国内生产总值（=0.008）、医院是否为专科医院（=0.002）或三级医院（<0.001）、硕士和博士学位医生的比例（<0.001）以及35岁及以下医生的比例（=0.005）与BI-RADS使用率显著且独立相关。中国医院乳腺癌超声诊断的平均准确率为73.64%，我们观察到人均国内生产总值（=0.02）、BI-RADS使用率（=0.019）与乳腺癌超声诊断准确率之间存在显著正相关。
BI-RADS模板的使用有效提高了超声诊断准确率。此外，该调查总结了中国大陆提供乳腺超声诊断的科室和超声医师的现状，有助于监测该学科的发展，并为管理人员满足不断增长的需求提供信息。
