Electronic Health Records (EHRs) rely on well-defined interoperability standards to communicate effectively across diverse healthcare environments. HL7 Version 2 remains widely used for messaging, particularly for admissions, discharges, and lab results. Clinical Document Architecture (CDA) standardized clinical summaries, enabling consistent document exchange. However, the rise of FHIR has redefined interoperability by combining modern web technologies with granular data access. FHIR supports RESTful APIs, JSON, and XML formats, making integration faster and more flexible for developers. Alongside these frameworks, terminology standards like SNOMED CT and LOINC ensure clinical meaning remains consistent across systems. Together, these standards reduce ambiguity, enhance data quality, and allow healthcare applications to scale. By aligning EHR implementations with these standards, organizations future-proof their systems and support innovation across the care continuum.
