Introduction. The experience and opinion of patients is increasingly recognized as one of the conditions for successful delivery of medical care, along with patient safety and clinical effectiveness. Despite international agreement on the importance of the concept of patient satisfaction with medical care and the need to monitor it, there is no consensus on its theoretical description and understanding of its constituent elements. The absence of a specific interpretation of the concept of “patient satisfaction with medical care” is confirmed by its ambiguous mention in various strategic development documents. The presence of disagreements on this issue does not allow the formation of the entire range of effective measures to improve patient satisfaction with medical care. The purpose of this work is to summarize studies and theoretical constructs that describe the concept of patient satisfaction with medical care in order to form approaches aimed at improving this indicator. Materials and methods. The search for publications on the selected topic was carried out in the databases PubMed, Google Scholar, eLibrary, Web of Science, Scopus, which are freely available. Key words were used as search markers: satisfaction (satisfaction), patient (patient), service sector (customer service), theory (theory). A total of 2,590,000 publications were found. After excluding publications that are not articles in peer-reviewed scientific journals, 1,030,000 records remained, from which meta-analyses, review studies, as well as publications aimed at determining the level, tools, factors affecting patient satisfaction with medical care, and See also publications exploring customer satisfaction in other areas. 42 publications were selected and included in the review. Results. An analysis of the concepts of satisfaction in marketing and consumer theories in relation to customers in the service sector, as well as 11 theories of satisfaction developed on their basis, was carried out, their similarities and differences were identified. According to the results of the study of the essence of patient satisfaction, a theoretical construct was formed. Discussion. The established theoretical construct makes it possible to create a unified framework for the use and interpretation of the concept of UPMP throughout the Russian Federation. Moreover, the formed elements of the construct make it possible to identify the directions of the main predictors of satisfaction, which are formed on the basis of the experience, expectations and ideas of patients, as well as the capabilities of the medical organization. Conclusion. Based on the study and the obtained theoretical construct, it seems possible to develop corrective measures to increase the level of satisfaction both at the level of the constituent entities of the Russian Federation and at the level of individual medical organizations.
