Health Level 7 - Understanding the Standard
Health Level 7: A Comprehensive Guide
Health Level 7 (HL7) is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. It plays a crucial role in the interoperability of healthcare systems, ensuring that different systems can communicate and work together effectively. Let's delve deeper into this important standard.
Key Components of HL7
HL7 consists of several key components that facilitate the exchange of health information:
- HL7 Reference Information Model (RIM)
- HL7 Clinical Document Architecture (CDA)
- HL7 Fast Healthcare Interoperability Resources (FHIR)
