Hospital EHR
The Hospital EHR is the source-of-record inside the hospital. It pushes HL7 v2 messages — notably ADT admissions and updates — to the platform over MLLP.
Integration contract
Messages must receive a timely ACK/NAK from the HL7 Gateway. Raw payloads are archived before mapping so compliance can replay if needed.
