This study presents a comparative analysis of the development of unified healthcare information systems (UHIS) in North America, Europe, and Africa. The research examines key aspects of UHIS implementation, including population coverage by electronic health records, telemedicine development, system interoperability, and regulatory frameworks. The analysis revealed significant regional differences in approaches to healthcare digitalization and UHIS implementation levels. North America is characterized by high digital technology adoption but faces challenges in integrating disparate systems. The European region shows heterogeneity, with Northern European countries leading, while Southern and Eastern Europe lag in UHIS development. The African continent presents the most contrasting picture, with a small group of leading countries and most states in the early stages of digitalization. The study identified common challenges across all regions, including ensuring interoperability, protecting personal data, and overcoming healthcare professionals' resistance to change.
Special attention is given to innovative approaches, such as the use of mobile technologies in Africa to overcome infrastructure limitations. The research results emphasize the need for a comprehensive approach to UHIS implementation, considering not only technological but also socio-economic factors. The study concludes that successful UHIS development requires a clear national strategy, adequate funding, and active involvement of all stakeholders.
