Aim. The presented study aims to identify problems in the implementation of the primary health care modernization program and to propose possible solutions through the example of the Moscow region.Tasks. The authors determine the role of modernization in the health care industry; analyze the experience of implementing the primary health care modernization program in the Moscow region; build a model of demand for medical services that reflects the impact of such factors as physical accessibility and time costs on the achievement of program goals.Methods. This study uses comparative analysis, description, generalization, systematization, and modeling to analyze program data for 2020-2021.Results. Human resources have the most potential for health care activities, which requires support through economic incentives and benefits to stimulate employees. The roles of stakeholders in the organizational management system of the departmental target program are determined, which affects the allocation of limited resources. The spending of budget funds during the unstable growth of modernization costs, where public procurement serves as the main means for achieving goals, is analyzed. Measures to monitor the progress of events and decision-making, engaging specialists and independent experts for a transparent modernization process, are proposed. A model of demand for medical services is built, where time costs are a factor limiting the accessibility of medical care for consumers with low income. It is determined that the demand for medical services becomes more sensitive to changes in time costs, which affects the accessibility of medical care.Conclusions. The health care modernization program is an instrument of state regulation of socio-economic policy in the field of medicine. The results of this study can be used by economic entities to effectively manage government programs with limited resources. Special attention should be paid to logistics, which is a functional area of project management. There is a need for an independent commission to independently evaluate the interim results of the program.
