Evaluation of current status in implementation of WS 582-2017 Specifications for testing of quality control in X and γ ray stereotactic radiotherapy system
Objective To investigate WS 582-2017 Specifications for testing of quality control in X and γ ray stereotactic radiotherapy system(hereinafter referred to as WS 582-2017)with respect to its current status,existing problems and evaluation since its implementation in Beijing,Chongqing,Jiangsu and Sichuan.Methods The evaluation of this standard was carried out by means of field survey,questionnaire survey and expert seminar.In accordance with the WS 582-2017 implementation assessment programme,a total of 153 professionals involved in the implementation of WS 582-2017 from 80 radiological health technical service institutions,health supervision institutions and medical institutions of two municipalities and two provinces were surveyed in 2023.The investigation was carried out by using a combination of cluster sampling and stratified sampling and through sampling professionals with of different institution characteristics and different technical titles.The general survey method was used for Jiangsu province,while the cluster sampling method was used for others,with 153 individulas from 80 institutions being sampled for the investigation.Results The awareness rate of WS 582-2017 was 80.39％,of which 90.85％considered it to be scientific and rigorous,81.05％considered it to be operational and 97.39％considered it to be in consistency with the relevant regulatory standards,90.20％considerd it to have played an important role in promoting radiological protection optimization for radiotherapy,90.85％considered the implementation of it to have played a significant role in the quality control of standarded testing of radiotherapy equipment,and 86.93％considered the implementation of it to have played a significant role in enhancing the professional competence of relevant technicians.Conclusions The overall implementation of WS 582-2017 in two municipalities and two provinces is good,with scientific and operable technical contents and the remarkable effect achieved in its implementation.However,the WS 582-2017 needs to be further improved in some areas,and training on the standard needs to be strengthened to improve the awareness rate of it.
