Analysis of 2017 evaluation results of medical radiation protection monitoring program in China by using the fuzzy combined method of TOPSIS and rank sum ratio

Objective To analyze 20 indicators for the evaluation of medical radiation protection monitoring in 31 provinces, municipalities or autonomous regions in 2017 and provide technical support and reference for further optimization of medical radiation protection monitoring projects. Methods According to " medical radiation protection monitoring assessment score sheet for medical and health institutions" , a full range of analysis and evaluation was carried out of medical radiation protection monitoring and implementation at nationwide medical and health institutions by using fuzzy combined method of TOPSIS and rank sum ratio. Results TOPSIS method and rank sum ratio weighted fuzzy joint analysis showed that the top three indicators, in descending order, were management of provincial implementation plans, management of project leaders in various cities and management of funds whereas the lowest three indicators were completion of radiotherapy equipment commissioning, innovation and highlights and tcoverage of radiotherapy equipment. Conclusions The fuzzy combined application of TOPSIS method and rank sum ratio method can provide the comprehensive quantitative result for the implementation of medical radiation protection monitoring in 2017, objectively evaluate the implementation of various indicators, summarize the highlights and bottlenecks of work in 2017, and provide technical support and reference for further optimization of medical radiation protection monitoring.
