Epic Systems Expands FHIR API for Radiation Oncology
EMR provider Epic Systems is continuing to expand its FHIR (Fast Healthcare Interoperability Resources) API capabilities, now targeting complex domains like radiation oncology. This development enables more granular, real-time data integration for specialized clinical environments. The move reflects a broader industry trend toward interoperability, a key requirement for modern healthcare analytics platforms.
- This expansion adds 12 new FHIR integration points specifically for radiation oncology, designed to support the CodeX (Common Oncology Data Elements eXtensions) implementation guide for exchanging radiotherapy summaries. - Radiation oncology data is notoriously complex and has been siloed in specialized Oncology Information Systems (OIS) like Varian's ARIA and Elekta's MOSAIQ, which are distinct from enterprise EHRs. Epic's FHIR APIs aim to bridge this gap, not by replacing these systems, but by integrating with them to handle scheduling and documentation. - The new FHIR resources will standardize data for radiotherapy treatment summaries, including details on courses, phases, and plans, which has historically been a manual and unstructured process. This structured data is critical for improving care coordination between radiation oncology and the broader oncology care team. - This move is aligned with the 21st Century Cures Act, which mandates greater interoperability and patient access to their electronic health information through standardized APIs like FHIR. Penalties for information blocking can be up to $1 million per violation. - The standardization of radiation oncology data through initiatives like mCODE (minimal Common Oncology Data Elements) and its adoption within FHIR is a collaborative effort involving organizations like the American Society for Radiation Oncology (ASTRO) and the American Association of Physicists in Medicine (AAPM). - By structuring this complex data, the new APIs can improve the quality and efficiency of treatment planning, which is where most errors in radiation oncology originate. It also facilitates the use of this data for AI-driven applications, such as predictive analytics for treatment outcomes and automated treatment planning. - Epic's broader interoperability network, Care Everywhere, already exchanges over 20 million patient records daily, with about half of those transactions occurring with organizations using different EHR systems. This new expansion brings a highly specialized and data-intensive field into this interoperable ecosystem. - The CodeX FHIR accelerator, which this Epic update supports, is a community-driven initiative working to accelerate the adoption of FHIR for high-quality, computable data in cancer care and research.
