Introduction. In the Russian Federation, a set of measures is being implemented aimed at the digital transformation of the social sphere. The basic element of the unified digital circuit is the Unified State Information System in the Healthcare Sector (EGISZ). The need to create the system is dictated by the need to consolidate information on the health status of citizens and the activities of medical organizations. Methods. During the study, general scientific methods of systematization, generalization, formal legal and comparative legal methods were used. The source of empirical material was normative legal acts, statistical data on the functioning of EGISZ, and materials of law enforcement practice. Analysis. EGISZ is a federal state information system operated by the Ministry of Health of Russia. The system includes sixteen subsystems that ensure the collection, processing and provision of information in the healthcare sector. The introduction of EGISZ contributes to improving the availability of medical care through electronic registration and telemedicine technologies. However, problems of data fragmentation between public and private segments remain, along with the absence of direct information exchange between clinics and low participation of private medical organizations in the unified digital circuit. Conclusions. The article examines the legal and organizational foundations of the functioning of EGISZ. Conclusions are drawn about the need to improve the regulatory framework to eliminate legal conflicts, ensure interoperability of medical information systems, and stimulate the integration of the private sector into the unified information space of healthcare.
