In the context of modern patient-oriented healthcare, issues of efficiency assessment cannot be considered in isolation from public opinion. In assessing the efficiency of medical organizations, great importance is attached to patient satisfaction with the quality of medical care. Currently, the main tool for assessing patient satisfaction with medical care is conducting sociological surveys (in the form of questionnaires, interviews, telephone surveys). However, according to some authors, there are some shortcomings in survey-based studies. Since 2019, patients can leave feedback through various channels, which is accumulated in the eCSRs. Purpose. This article analyzes patient feedback to determine whether the frequency and structure of feedback reflect patient satisfaction with medical care. Materials and methods. The analysis of appeals from citizens of the Moscow region to government bodies at all levels, accumulated in the eCRM of the Moscow region and classified by artificial intelligence into the thematic category "Healthcare", for 2023. The analysis also analyzes patient satisfaction indicators with medical care based on the results of an independent assessment of the work of medical organizations in the Moscow region. Results. Of all the requests, experts from only 7 subcategories characterize the availability and quality of medical care. The number of requests for the 7 selected subcategories amounted to 23.1% of all requests. That is, almost a quarter of all requests from patients are related to the quality and availability of medical care, of which slightly more than half are justified requests, and more than 40% are unjustified. A relationship was found between the number of requests and patient satisfaction. Thus, among 83 state medical organizations, for which an independent assessment of the quality of service provision conditions was conducted, organizations with a smaller number of requests occupy higher positions compared to organizations with a large number of requests, which generally corresponds to the general trend of patient satisfaction. Discussion. The presence of a large number of unfounded requests indicates patient dissatisfaction with medical care, while dissatisfaction does not lie in the plane of specific problems, but concerns the systemic situation of health care, which is often difficult for patients to formalize. The number of patient requests reflects the general trend of patient satisfaction with medical care, this is proven by the fact that medical organizations with fewer requests are higher in the overall rating of all state medical organizations. However, given the fact that the number of points is quite high for those organizations that have the most requests, the satisfaction assessment is not very informative and does not contribute to improving the quality of medical care, since it does not reveal individual problems in the provision of medical care. Conclusion. Thus, the frequency and structure of patient feedback regarding the activities of medical organizations reflects patient satisfaction with medical care.
