A FHIR -CENTRIC APPROACH FOR INTEROPERABLE REMOTE PATIENT MONITORING

Abstract

Interoperability of health information systems is one of the main challenges in modern clinical practice. Healthcare institutions often use different ICT solutions that do not communicate with each other, which leads to fragmented data, duplicate data, limited access to important patient information, and potential risks in making clinical decisions. The key problem lies in the absence of a universally adopted standard for the exchange of health information data. As a potential solution to this situation, the HL7 FHIR standard appears, developed to enable fast, easy, and secure exchange of health information, resulting in efficiency and consistency in patient care. This paper presents a practical implementation of the FHIR standard through the development of a specialized platform for blood pressure monitoring. The system architecture includes a mobile application intended for patients and a desktop-based application intended for doctors, which communicate via a RESTful API in accordance with the FHIR specification. The implementation demonstrates how the FHIR standard enables seamless interoperability, efficient exchange of structured data, and improved collaboration between patients and doctors, confirming its fundamental role in overcoming structural barriers in the context of modern e-health.
