The article is devoted to the study of the issue of changing the functionality of nurses, analyzing the opinions of nurses and doctors themselves on the implementation of such an innovation, assessing the benefits and consequences associated with expanding the functions and increasing the role of nurses in the medical community. The research is based on CHAID-analysis of data from a questionnaire survey conducted in 2020, which revealed the respondents' attitude to the idea of improving the status of nurses and expanding their functions, expectations of the possible reaction of the medical community and patients to this innovation, and the development of so-called «trees» of classifications for various variables. The collected and systematized data on changes in the functionality of nurses can serve as a starting point for the possible expansion of the functions and powers of nurses in the metropolitan health care, as well as increasing the role and status of nurses in the professional environment. The results of the Moscow study presented in the article confirm the conclusions of other scientists and practitioners from the Russian regions, in which a pilot project has already been implemented to change the functionality of nurses.
