XVII.RIS Connectivity Installation
Rilink and Rideliverd are background processes used in the RIS connectivity package. Rilink
receives HL7 messages from RIS systems, and writes each message into a specified directory on
disk. Rideliverd reads each message, and determines how to handle it based on the type of
message. An ORU message is a report message containing a verified report, and rideliverd will
try to associate the report with a matching exam. A ORM message, or general order message, is
used to provide worklist (scheduling) information and also alter patient demographics. If
everything works correctly, Rilink will receive and deposit the messages. Rideliverd will read
each message, provide the functionality required, and then delete each successfully handled
message. Thus the hl7msg directory should only provide temporary storage for messages being
processed.
Rideliver is a third application in the RIS connectivity package which allows manual
reconciliation of mis-matched reports.
