我国医院医用直线加速器配置适宜性评价

Assessment and analysis for deployment appropriateness of medical linear accelerator at hospitals in China

分析我国医院医用直线加速器的配置情况,评价其适宜性,为我国医院医用直线加速器的配置提供建议.方法 2017年6月至2018年11月,采取分层随机抽样的方法抽取26家医院进行调查.运用描述性分析对26家样本医院医用直线加速器的配置情况及人员配置情况进行分析,使用TOPSIS综合评价法对医用直线加速器的配置适宜性进行评价.结果医用直线加速器配置数量在各级医疗机构间差异明显;80%(12/15)的三级医院配置了进口品牌医用直线加速器,二级医院中仅有9%(1/11)配置进口品牌医用直线加速器;专业人员整体配备基本上合理,较少数医院的物理师配备不足.三级医院医用直线加速器配置适宜性优于二级医院, 80%(12/15)的三级医院获得"良好"及以上评级, 91%(10/11)的二级医院获得"一般"及以下的评级.结论医院应立足实际情况和需求进行大型医疗设备的配置;应加强对放疗专业技术人才的培养;应加强对医用设备规划、准入、监督方面的管理.

Objective To analyze the deployment of medical linear accelerators at 26 hospitals in China, and suggest on the deployment of such accelerators. Methods From June 2017 to November 2018, a total of 26 hospitals were surveyed by stratified random sampling.Descriptive analysis of the deployment and staffing of medical linear accelerators at 26 hospitals, and the deployment appropriateness of the medical linear accelerator was evaluated using the TOPSIS method. Results The number of medical linear accelerators in different types of hospitals was significantly different.The proportion of imported equipment at tertiary hospitals was 80%(12/15) and the proportion of imported equipment at secondary hospitals was 9%(1/11). The professional staff was deployed basically reasonable, and there was a shortage of physicists at some hospitals.The suitability of medical linear accelerators at tertiary hospitals was better than that of secondary hospitals, 80%(12/15) of tertiary hospitals received " good" and above ratings, while 91%(10/11) of the secondary hospitals received " general" and below ratings. Conclusions Hospitals should carry out the allocation of large-scale medical equipment based on their own situations and requirements.Efforts should be paid on training of professional technicians for radiotherapy.It is important to strengthen the management of planning, access and supervision of medical equipment.
