EHR Interoperability • HL7 FHIR R4
Zero rip and replace.
Works with what you already have.
WeCareE is built on FHIR R4, the federal standard for health data exchange. Your existing EHR stays. Your nurses get a better tool at the bedside. PointClickCare and MatrixCare connectors roll out with our pilot facilities.
HOW FHIR R4 WORKS
FHIR R4 — the interoperability standard that connects
WeCareE to your EHR.
FHIR R4 (Fast Healthcare Interoperability Resources, Release 4) is the current federal standard for healthcare data exchange. It is the same standard used by Epic, Cerner, the VA, and mandated by CMS for all EHR systems under the 21st Century Cures Act.
WeCareE writes every clinical record (wound assessments, vital signs, medication administration, nursing assessments) to GCP Cloud Healthcare API in FHIR R4 format. EHR read connections come first; write-back follows as each EHR partner approves it.
