目的了解医疗机构相关人员对现行WS 531—2017《螺旋断层治疗装置质量控制检测规范》实施过程中的科学性、适用性及可操作性等方面情况进行跟踪评价,为进一步完善该标准提供科学依据。方法依据WS/T 536—2017《卫生标准跟踪评价工作指南》和项目实施方案,对国内9个省内配置了螺旋断层治疗装置(以下简称TOMO)的医疗机构中使用TOMO相关工作人员进行问卷调查,问卷采用预调查、现场调研、邮寄、电子邮件等方式开展。获得数据后,采取双录入法,借助EpiData 3.1软件建立调查数据库,然后采用office 2013进行数据统计分析。结果共收集到医疗机构相关人员问卷16份,其中有效问卷15份,有效率94%。医疗机构相关人员对标准的总体和文本格式满意度分别为75%和82%;73.3%的医疗机构相关人员知晓标准发布情况;对标准的内容"熟悉"、"一般"和"不熟悉"分别为71%、29%和0;对标准中的术语及定义"完全理解"、"部分理解"和"不理解"分别为93.3%、6.7%和0;标准检测指标及其限值的"不知晓"、"部分知晓"和"熟练掌握"分别为13.3%、13.3%和73.3%;按照标准内容进行TOMO质控检测中"全部按照"、"部分按照"和"不按照"分别为61.5%、30.8%和7.7%;12家医疗机构中认为开展质量控制检测存在问题的原因"标准普及程度低"、"标准理解程度不足"、"检测指标难理解"、"标准滞后跟不上发展"和"标准制定检测设备难达到"分别占91.7%、50.0%、33.3%和8.3%和0;医疗机构相关人员理解TOMO质量控制检测设备,且能够开展稳定性检测工作。结论医疗机构相关人员对标准总体和文本格式的满意度高,认为标准能够满足TOMO质控的需要;医疗机构相关人员知晓标准的基本情况和内容,但对内容理解程度有待提高;建议后续对医疗机构加强标准培训、宣贯力度和能力建设。

Objective To understand the implementation of the current "Specification for testing of quality control in helical tomotherapy unit(WS 531—2017)" by the relevant personnel of medical institutions, and to provide scientific basis for the further improvement of the standard. Methods According to "Guideline for health standards tracking evaluation(WS/T536—2017)" and the implementation plan of the project, questionnaire survey was carried out among the relevant personnel in 9 domestic medical institutions with TOMO, The follow-up and evaluation work were carried out by means of pre-survey,on-site survey, mail and e-mail, etc. After obtaining the data, the double input method was adopted to establish the survey database with EpiData 3.1 software,and then the statistical analysis of the data was carried out using office 2013.Results A total of 16 questionnaires were collected from relevant personnel of medical institutions, among which 15 were valid, with the effective rate of 94%. The satisfaction of the staff of the medical institutions to the overall and text format of the standard were 75% and 82%, respectively; 73.3% of medical institutions knew the release of the standard; 71%, 29% and0% were familiar with, general and unfamiliar with the content of the standard, respectively; 93.3%, 6.7% and 0% were fully understanding, partially understanding and incomprehensible with the terms and definitions of the standard, respectively.Standard test indicators and the limits of "unknown", "partial known" and "proficient mastering" were 13.3%, 13.3% and 73.3%, respectively. According to the standard contents, "all in accordance", "part in accordance" and "not in accordance" in the quality control test of TOMO were 61.5%, 30.8% and 7.7%, respectively. Among the 12 medical institutions, 91.7%,50.0%, 33.3%, 8.3% and 0 of them think that the reasons for the problems in the quality control testing were "low popularity of the standard", "insufficient understanding of standard", "difficult to understand test indicators", "lagging behind the development of standard", and "difficult to achieve standardized testing equipment", respectively. All the relevant personnel of the medical institutions were able to understand the quality control testing equipment and carry out the stability test of TOMO.Conclusion The relevant personnel of medical institutions were highly satisfied with the overall and text format of the standard. They thought that the standard could meet the quality control needs of TOMO. The relevant personnel knew the basic situation and content of the standard, but their understanding to the content needed to be improved. It was suggested to strengthen the training、publicity and implementation of the standard and the capacity-building of the institutions.
