The healthcare industry faces increasing challenges in managing and integrating vast volumes of electronic health data distributed across disparate systems. Historically, the HL7 v2 standard addressed many interoperability concerns, but evolving requirements and system complexities have highlighted its limitations. HL7 standards aimed to facilitate seamless data exchange through well-defined protocols, collaborative input from stakeholders, and international standardization. However, with diverse communication protocols and a fragmented ecosystem of Electronic Medical Records (EMRs), consistent integration remains difficult. The emergence of HL7 FHIR (Fast Healthcare Interoperability Resources), designed by Grahame Grieve, offers a modern, flexible, and scalable solution. Leveraging RESTful APIs, OAuth, and SMART on FHIR, FHIR focuses on real-time, standardized access to health data across internal and external systems. Its design reduces vendor lock-in and enables the development of EMR-agnostic applications, addressing many limitations of earlier HL7 versions and traditional integration approaches
