评价2016—2023年西藏自治区产前超声筛查专项培训学员的人员结构、从业情况及培训效果，为后续产前超声筛查专项培训工作的优化提供数据支持。

2016年7月至2023年12月，按照中国出生缺陷基金会培训大纲、国际妇产科超声学会指南，通过理论授课、实践操作带教及病例讨论等方式，对参加培训的西藏自治区7个地市120家医院2000余名学员进行规范化产前超声筛查培训，并对1475名学员开展问卷调查（现场及数字化问卷），对培训学员人员结构、从业情况及培训效果进行总结分析。

在8年的培训工作开展期间，培训团队为西藏自治区构建起“产前超声标准化培训体系”，组建了专业的产前超声筛查与诊断医师队伍，并采集了1475名培训学员及所属医院的基础信息；其中，241名超声医师获得由中国出生缺陷基金会和国家培训基地颁发的产前超声诊断证书，1000余名医师在线培训成绩合格获得西藏自治区超声医学会颁发的产前超声筛查培训证书。培训学员年龄以20~29岁居多（40.4%），学历以本科居多（57.4%），初、中级职称人员占比达72.1%，专业以影像及临床专业为主。来自二级医院的培训学员占比最高（46.3%），来自三级医院的学员占比为41.1%。63.3%的医院选派过一半以上人员接受专业培训。培训成效显著：西藏自治区胎儿畸形检出数占分娩总人数的比例由2015年的0.48%上升至2016—2023年8年间的年均1.99%，同时，每位孕妇在孕期能接受1~2次产前系统超声检查。

8年培训调查数据显示,参加培训的医院和人员等级结构合理，为西藏自治区产前超声持续健康发展奠定了良好的基础。

To evaluate the effect of the special training for prenatal ultrasound screening in Xizang Autonomous Region from 2016 to 2023, and to analyze the personnel structure, professional status, and training outcomes of trainees, with an aim of providing data-driven support for the optimization of subsequent special training programs in prenatal ultrasound screening.

From July 2016 to December 2023, based on the training outline of the China Birth Defects Foundation and the guidelines of the International Society of Ultrasound in Obstetrics and Gynecology, standardized prenatal ultrasound screening training was carried out. It was conducted for more than 2000 trainees from 120 hospitals across 7 regions of Xizang Autonomous Region, utilizing methods such as theoretical lectures, practical teaching, and case discussions. A questionnaire survey (on-site and digital) was carried out among 1475 trainees to summarize and analyze their personnel structure, professional status, and training effect.

During the eight-year training period, a "standardized prenatal ultrasound training system" was established for the Xizang Autonomous Region, and a team of physicians proficient in prenatal ultrasound screening and diagnosis was formed. Basic information of 1475 trainees and their affiliated hospitals was obtained. A total of 241 ultrasound physicians were certified in prenatal ultrasound diagnosis by the China Birth Defects Foundation and national training bases, while over 1000 physicians passed the online training and received prenatal ultrasound screening training certificates from the Xizang Ultrasound Medical Association. The majority of the trainees were aged between 20 and 29 (40.4%), and the majority had a bachelor's degree (57.4%). The proportion of those with junior or intermediate professional titles reached 72.1%, and their specialties were mainly imaging and clinical medicine. The proportion of trainees from secondary hospitals was the highest (46.3%), while those from tertiary hospitals accounted for 41.1%. More than half of the staff in 63.3% of the hospitals had received professional training. After the training, the proportion of fetal malformation detection in Xizang Autonomous Region to the total number of deliveries increased from 0.48% in 2015 to an annual average of 1.99% during the 8 years from 2016 to 2023. Each pregnant woman could receive 1-2 prenatal systematic ultrasound examinations during pregnancy.

The 8-year training survey data show that the hierarchical structure of both the participating hospitals and trainees is reasonable, laying a good foundation for the healthy and sustainable development of prenatal ultrasound services in the plateau.
