The issues of quality management of medical care and organization of the work of the department of radiation diagnostics are always relevant and require constant monitoring and analytical expertise. Since 2018, the Moscow regional branch of the Russian Society of Radiologists and Radiologists (MRO PORR) has been conducting an independent assessment of the departments of radiation diagnostics in all regions of Russia. This paper presents an analysis of the functioning of 123 departments of radiation diagnostics in 2020. After the end of accepting applications for participation in the rating, a list of 163 medical organizations in 15 cities of 7 federal districts was formed. The evaluation procedure was divided into three stages. At the first stage, an online survey took place, during the second stage, a clinical and technical audit of a set of anonymized studies with conclusions was carried out, and the third stage included checking information about medical organizations in open sources. During the first and second stages, points were awarded, on the basis of which the finalists, leaders and rating winners were selected. Based on the results of the survey, positive trends in the development of diagnostic care services throughout the country and critical points affecting the quality of work of medical organizations were identified.
