How FHIR Enables Agentic AI in Healthcare
How FHIR Enables Agentic AI in Healthcare | by Michael
Summary
Agentic AI refers to systems that autonomously take action toward a goal, going beyond simple question answering. To realize this advanced capability, standardized data access and mechanisms for action provided by FHIR are essential.
Details
Agentic AI is defined as a system capable of taking autonomous action towards a goal, rather than merely generating text or answering questions. While current clinical AI is largely advisory—requiring human execution after an AI suggestion—true agentic AI aims to invert this: the AI executes, and the clinician supervises. This requires consistent interfaces for reading data from and writing actions to multiple clinical systems, such as EHRs. Without standardization, every deployment becomes bespoke, requiring different API calls and data formats per hospital, which prevents scalable workflows. FHIR solves this by providing a foundational layer. Using standardized resource structures (Patient, Observation) and RESTful API patterns, systems can execute portable logic across different EHR vendors like Epic or Cerner. Crucially, referencing standard terminologies such as SNOMED CT (findings), LOINC (labs), and RxNorm (medications) allows the AI to make safe decisions based on coded data rather than free text. This capability enables progress from read-only recommendations to writeable automation, providing the necessary technical foundation for realizing autonomous clinical workflows.
