HL7 Version 2 Product Suite

DESCRIPTION

HL7’s Version 2.x (V2) messaging standard is the workhorse of electronic data exchange in the clinical domain and arguably the most widely implemented standard for healthcare in the world. This messaging standard allows the exchange of clinical data between systems. It is designed to support a central patient care system as well as a more distributed environment where data resides in departmental systems.

TARGETS

  • Healthcare IT Vendors
  • Healthcare Providers

BENEFITS

  • Supports the majority of the common interfaces used in the healthcare industry globally
  • Provides a framework for negotiations of what is not in the standard
  • Reduces implementation costs
  • Generally backward compatible

IMPLEMENTATIONS/CASE STUDIES

See the Implementation Guides for this Standard.

  • 95% of US healthcare organizations use HL7 V2.x
  • More than 35 countries have HL7 V2.x implementations

DEVELOPMENT BACKGROUND

As one of the most widely implemented standards for healthcare information in the world, the Version 2 Messaging Standard was first released in October 1987 as an Application Protocol for Electronic Data Exchange in Healthcare Environments. Version 2.7, representing the latest update to the Version 2 Standard, was published in 2011.

 

Due to its widespread use, Version 2 will continue to play an integral part in healthcare messaging, even with the HL7 Version 3 Normative Edition. HL7 is committed to supporting and extending Version 2 in parallel with Version 3, providing continuity for current installations.
