Overview [1]#

Health Level Seven (HL7), is an all-volunteer, not-for-profit Entity involved in development of international healthcare standards.

Health Level Seven (HL7) is also used to refer to some of the specific standards created by the organization (i.e. HL7 v2.x, v3.0, HL7 RIM etc.).

Health Level Seven and its members provide a framework (and related standards) for the exchange, integration, sharing and retrieval of electronic health information. The standards, which support clinical practice and the management, delivery, and evaluation of health services, are the most commonly used in the world.

Fast Healthcare Interoperability Resources [3]#

Fast Healthcare Interoperability Resources (FHIR) is a next generation standards framework created by Health Level Seven (HL7). Some of the protocols within HL7:

Minimal Lower Layer Protocol (MLLP)#

A large portion of HL7 messaging is transported by Minimal Lower Layer Protocol (MLLP), also known as Lower Layer Protocol (LLP). For transmitting via TCP/IP, header and trailer characters are added to the message to identify the beginning and ending of the message because TCP/IP is a continuous stream of bytes. Hybrid Lower Layer Protocol (HLLP) is a variation of MLLP that includes a checksum to help verify message integrity.
