The aim of this publication is to present the results of research on the use of AI tools' potential in revolutionizing healthcare services.The book presents a study on the identification of unmet health needs in aging societies, indicating a gap in the supply of medical services. While the senior population is among the groups that frequently use healthcare services and where the demand gap is particularly visible, they are presented to better illustrate the need and the potential of AI tools. The proposed models and recommendations have broader applications, addressing different patient groups and entire healthcare systems outlining the benefits and risks of using AI in the healthcare market. Moreover, the authors will focus on the implementation of AI tools that have not yet been adopted due to organizational and legal barriers in medical entities. The book also presents legal regulations aimed at establishing systemic liability of entities in the medical sector and protecting confidential data stored and processed in these systems, with particular emphasis on the legal protection of seniors in the health services market in the era of AI development. Furthermore, the authors will explore cutting-edge technologies that ensure the safety of AI use in medical services. These technologies enable healthcare providers to deliver interactive, health-promoting tools to healthcare providers and patients based on the latest medical, pharmaceutical, and IT knowledge. By equipping patients with accurate information about their health status and treatment regimens, these tools mitigate the risks associated with misinformation from unreliable sources, thereby supporting informed decision-making in healthcare.
