HL7 is the universal user-friendly standard that enables the communication between two or more healthcare management applications. The health-related information will be transferred in the form of one or more HL7 messages such as patient record and billing information.
The HL7 interoperability standard is often called the nonstandard standard, since it does not consider any specific part as special and, hence, there is no standard business or clinical model for clinical interaction.
HL7 development needs the involvement of clinical application analyst, integration specialist, application programmers and system analyst.
What does HL7 stand for?
HL7 (Health Level Seven) symbolizes a 7-layer ISO communication model
Physical: Connects the entity to the transmission media
Data Link: Provides error control between adjacent nodes
Network: Routes the information in the network
Transport: Provides end-to-end communication control
Session: Handles problems that are not communication issues
Presentation: Converts the information
Application: Provides different services to the applications
1-4 deals with Communication; 5-7 deals with Function. All these layers are used by HL7 interface engine for transfer and retrieval of HL7 data.
