The aim of this paper is to analyze and compare expenditures on preventive healthcare services in the Czech Republic during the period from 2010 to 2021. Using descriptive, deductive, and comparative methodologies, the study evaluates the components of healthcare expenditure within the context of GDP, a key indicator of economic activity. The findings suggest that the proportion of healthcare funding from state and local budgets likely increased during the COVID-19 pandemic due to a surge in demand for healthcare services and the expansion of public funding to address the crisis. Additionally, the study emphasizes the importance of demographic shifts, particularly the aging population, in influencing future healthcare costs. As the share of elderly individuals in the population grows, healthcare expenditures are expected to rise, especially in areas such as long-term care and preventive services. This demographic trend is projected to place increasing pressure on healthcare systems and public budgets in the coming years. The paper concludes that while economic growth can facilitate increased healthcare funding, long-term sustainability will depend on addressing the challenges posed by an aging population. Strategic planning and policy adjustments are necessary to ensure the adequacy of healthcare financing in light of these demographic changes.
