What Is An HL7 Interface Engine?

An HL7 interface engine is a central hub that receives, routes, and sends HL7 messages to the appropriate healthcare information systems. A modern interface engine:

  • Simplifies integration by connecting healthcare systems
  • Supports all HL7 versions: HL7 v2.x, v3.x, and more
  • Ensures HL7 messages are communicated in a fast, reliable, secure and cost effective manner
Iguana is a modern HL7 interface engine
