了解西藏自治区各级超声医疗机构基本情况，探讨超声医学质量控制工作面临的问题。

2022年1至12月西藏超声医学质量控制中心在援藏医疗团队协助下对西藏自治区87所超声医疗机构超声诊断基线情况及质量指标相关数据展开调查，并对超声医学质量控制工作提出一系列改进策略。

调查显示，西藏自治区超声医疗机构以二级医院为主（78%，68/87），三级医院数量少，仅占22%（19/87），区域内高等级医院分布不均；西藏自治区二级和三级医院超声医师配比明显不足，以住院医师和主治医师居多（71%，273/387），副高级以上职称超声医师匮乏，仅占9%（33/387）；全区在岗医师梯队技术力量薄弱，对超声危急值认识不足，上报数量少（三级医院802例，二级医院610例）。

基于西藏自治区不同等级医疗机构超声医学专业质量控制存在差异，遵照国家超声医学质量控制指南要求，制订质量管理控制和改进方案，逐步建立健全西藏自治区超声医学质量控制体系，提升西藏自治区超声医疗服务水平。

To survey the basic situation of ultrasonic medical institutions at all levels in Tibet Autonomous Region, to explore the problems in ultrasonic quality control, and to propose some improvement measures.

From January to December, 2022, Tibet Ultrasound Medical Quality Control Center, with the assistance of Tibetan medical aid team, investigated the basic situation of ultrasound diagnosis and related data of quality indicators in 87 hospitals in Tibet Autonomous Region, and put forward a series of improvement strategies for establishing ultrasound quality.

The survey showed that the ultrasonic medical institutions in Tibet Autonomous Region were mainly secondary hospitals (78%, 68/87), with limited tertiary hospitals accounting for only 22% (19/87). High-grade hospitals were unevenly distributed in the region. The proportion of ultrasound physicians in the secondary and tertiary hospitals in Tibet Autonomous Region was obviously low, with the majority being residents and attending physicians (71%, 273/387), and the ultrasound physicians with associate senior title or above accounted for only 9% (33/387). The skills of doctors in the second and tertiary hospitals in the region were poor, their understanding of ultrasound critical value was insufficient, and the reporting rate was low (tertiary hospitals: 802 cases; secondary hospitals: 610 cases).

In accordance with the national guidelines for ultrasound quality control, a quality control and improvement plan is being developed to establish a sound ultrasound quality control system in the Tibet Autonomous Region, with an aim to improve the level of ultrasound medical services in the region.
