医疗机构伽马刀稳定性检测现状分析

Analysis of current γ knife stability testing status in medical institutions

目的跟踪评价医疗机构依据WS 582—2017《X、γ射线立体定向放射治疗系统质量控制检测规范》(以下简称“WS 582—2017”)开展γ射线立体定向放射治疗系统(以下简称“伽马刀”)稳定性检测的现状。方法采用随机抽样方法,以43家配备有伽马刀医疗机构及其54名医学物理人员为研究对象,基于标准跟踪评价方法,开展有关依据WS 582—2017进行伽马刀稳定性检测的跟踪评价工作。结果54名研究对象中,仅66.7%的人员在日常工作中使用了WS 582—2017。43家医疗机构中,仅有30.2%的医疗机构(均为三级医院)配备了齐全的质量控制检测设备;伽马刀稳定性检测工作开展率为67.4%,但未严格按照WS 582—2017规定的检测项目和检测周期要求开展有关工作,且均不同程度地存在检测项目不全、记录不完整或检测周期不符合标准要求的现象。结论有关医疗机构未严格按照WS 582—2017要求的项目和周期开展伽马刀稳定性检测。其原因与医疗机构检测设备配备不全、对国家相关标准要求缺乏了解、标准的宣传贯彻不力、缺乏规范的培训渠道和卫生监督力度不足等有关。

Objective To follow up and evaluate the stability testing status ofγstereotactic radiotherapy system(hereinafter referred toγknife)in medical institutions based on the WS 582-2017 Specifications for Testing of Quality Control in X andγRay Stereotactic Radiotherapy System(hereinafter referred to WS 582-2017).Methods A total of 43 medical institutions usingγknife and 54 medical physics personnel were recruited as the research subjects by random sampling method.Based on the standard tracking evaluation method,we followed-up the evaluation ofγknife stability testing based on WS 582-2017.Results Only 66.7%of the 54 subjects preformed WS 582-2017 in their daily work.Only 30.2%(all were tertiary hospital)of 43 medical institutions were equipped with complete quality control and testing equipment.The implementation rate ofγknife stability test was 67.4%,and it was not carried out in strict accordance with the test events and test cycle requirements specified in the WS 582-2017.There were incomplete test events,incomplete records or test cycles that did not meet the standard requirements inγknife stability test.Conclusion Medical institutions did not carry outγknife stability tests in strict accordance with the projects and cycle required by the WS 582-2017.The reasons are related to medical institutions are not equipped with complete testing equipment,the personnel are lack of understanding of relevant national standards,the poor publicity and implementation of the standards,the lack of standardized training channels and inadequate health supervision.
