HL7 v2 ADT + FHIR R4 · healow Platform
eClinicalWorks uses a hybrid integration approach: we receive HL7 v2 ADT messages (admission, discharge, transfer) for real-time appointment events, and supplement with FHIR R4 API calls via the healow platform for structured patient data. This means you get live appointment updates and patient confirmations without your IT team managing complex interface servers. Most eCW practices go live without any middleware changes.
We work with your existing eCW configuration — no middleware changes required. The HL7 v2 ADT feed is typically already configured in your eCW environment for other integrations; CaseFlow connects to the same feed. Our team handles the connection setup — you just confirm the feed is active.
HIPAA BAA is signed before any connection is made. The HL7 v2 feed connection is authenticated and scoped — only appointment and patient demographic events are received. Data is encrypted at rest (AES-256) and in transit (TLS 1.3) via the healow FHIR endpoint.
30-minute call — we'll review your eCW configuration, confirm the integration approach, and give you a realistic go-live date before you commit.
