[Paradigm as a methodological approach to analyzing Russia's public health system].
A concept of paradigm is applied to the analysis of the national public health system. Whether it can be used as a methodological regulator in public health management is considered. Evidence is provided for the theoretical premises of constructing a paradigm of the public health system, its philosophical bases, the notional system, methodology, and the technological framework. The theoretical and practical aspects of public health paradigm, such as identification, interpretation, and rationalization are used to analyze at the conceptual and practical level, as well as search for new ways of reforming the public health system by the paradigm approach as a deeper development of the existing paradigm or its modification. This can become a foundation for the realignments of the theoretical and practical bases of the national public health system. The formation of the new paradigm of the public health system is to take place not in a revolutionary, but in a developmental mode. Priority should be given not to radical transformations and drastic changing of the key concepts, but to the fluent increasing of new knowledge and their inclusion of the theory and practice of public health. The promises of using the paradigm methodology, allowing the internal and external principles of the operation and function of the public health system to be integrated. In this context, the paradigm approach may be used as a methodological tool for analyzing person-society-state-economy-management relations within the framework of the public health system.
