EHR (Electronic Health Record)

An EHR (Electronic Health Record) is the digital system that stores patient records — Epic, Cerner (Oracle Health), Meditech, Allscripts being the dominant vendors. AI integrations with EHRs use the FHIR API standard for read access and dedicated SDKs (Epic's Hyperdrive, Cerner's CernerWorks) for write access. EHR integration is the slowest phase of healthcare AI deployment, often 2–4 months of work for a single workflow.
