The article examines the main legal, medical and social prerequisites for improving the healthcare system in Ukraine. The relevance of the study is determined by the disappointing statistics, which indicate a reduced survival rate and an increased mortality rate among the population of Ukraine compared to the most developed countries in the world. It is proven that the socio-economic well-being of the population is directly related to the development of the healthcare system. Modern world trends dictate the need to take into account and implement the relevant elements of 5P medicine: personalized, predictive, preventive, participatory and precision. The purpose of the article is to analyze the current state of Ukrainian legislation in the context of ensuring the functioning of the elements of 5P medicine, as well as the unification of the glossary, which makes it possible to shift the emphasis from the treatment of diseases to the personalized preservation of the health of each person. The advantages of the adoption of domestic legislation to the provisions of the law of the European Union are studied. An insufficient level of legal regulation of preventive medicine as one of the key directions of health preservation and disease prevention has been established. A distinction has been made between prophylaxis and preventive medicine, and the related concepts of "biohacking" and "health preservation" have been analyzed. Both general scientific and special methods of scientific research, in particular: dialectical, historical, comparative, formal-logical and systemic-structural analysis, etc., served as the optimal methodological basis of the study. Such a methodological system made it possible to start work on the development of an integrative legal model, which will be based on modern approaches to human-oriented medicine, which requires an interdisciplinary and complex approach to the tasks and further research in this field.
