The ongoing process of reforming national health care system determines associated search for systems of adequate decision-making based on comprehensive and objective analysis of activities of sector objects. The results of many years research demonstrate that one of the most effective such systems is system of assessing compliance of medical activities with established requirements. It is a methodology that permits to implement systematic comprehensive analysis of health care objects and make necessary decisions on its basis. This approach is extremely important for improving control and authorization-based mechanisms, justifying necessary resource support and developing comprehensive programs of development of isolated institutions, services and industry as whole. The term "conformity assessment" was introduced for the first time in the Federal Law № 184 of 27.12.2002 "On Technical Regulation". The given law defines concept of conformity assessment as direct or indirect compliance with requirements imposed on the object. The concept presented in this law regulates industrial activity to objects and subjects of technical regulation. It is this ideology that became a basis of actual study, in which methodology and organizational technology was developed and experimentally tested to assess compliance of medical organizations and individual health services with requirements established by current legislation. Within study framework, development and experimental testing of system of assessing compliance of medical activities with requirements of regulatory documents was carried out. The object of the study was medical organizations and their structural divisions.The significant increase was established in specially developed integral compliance coefficients for studied objects for 2016-2020: from 76.5% to 82.0% for a number of medical profiles selected for the study and from 72.0% to 78.0% for medical organizations. The data obtained indicate that on the basis of a set of balanced indices, administration of monitoring objects made adequate management decisions.
