HL7 collaborates with other standards development organizations and national and international sanctioning bodies ( e. g. ANSI and ISO ), in both the healthcare and information infrastructure domains to promote the use of supportive and compatible standards.

Currently HL7 in Germany operates as an informal cluster and collaborates with the national standardization body.

Diagnosis Report is sent back to HIS via HL7 usually and Images are sent back to HIS via DICOM usually if there is a DICOM Viewer integrated with HIS in hospitals ( In most of cases, Clinical Physician gets reminder of Diagnosis Report coming and then queries images from PACS Server ).

HL7 specifies a number of flexible standards, guidelines, and methodologies by which various healthcare systems can communicate with each other.

HL7 adopted and oversees the standard beginning with Arden syntax 2. 0.

The localisation of the HL7 standards is undertaken in cooperation with the national standards body, Standards Australia.

HL7 Australia closely cooperates with the National E-Health Transition Authority ( NEHTA ).

* Liaising with HL7 International ;

Nictiz coordinates its efforts with regard to the usage of HL7 version 3 with the volunteers of HL7 the Netherlands.

HL7 Pakistan is now officially authorized to give memberships to local organizations along with other privileges like certification, training, etc.

HL7 ’ s initial involvement in the Health Insurance Portability and Accountability Act ( HIPAA ) legislation began in 1996 with the formation of the Attachments special interest group to standardize the supplemental information needed to support health care insurance, and other e-commerce transactions.

The terminology is an American Nurses ' Association-recognized terminology, is included in the UMLS, is HL7 registered, ISO-compatible and available within SNOMED CT with appropriate licensure.

Respective standards are available with ISO / HL7 10781: 2009 Electronic Health Record-System Functional Model, Release 1. 1 and subsequent set of detailing standards.

There is no standardization but for data formats and for data interchange, as with the HL7 initiative supported by ISO.

* HL7 interfaces with reference labs and EMRs

* HL7 — used to communicate with hospitals, or EMR systems

The SeeBeyond ICAN suite is widely used in the healthcare industry because of its compliance with the HL7 and HIPAA standards.

* HL7 interfaces with a PACS.

The openEHR specification is not concerned with the exchange of data between EHR-systems as this is the primary focus of other standards such as EN 13606 and HL7.

* Common Terminology Services, an HL7 ANSI standard of requirements for interoperability across disparate healthcare applications

Health Level Seven ( HL7 ), is a non-profit organization involved in the development of international healthcare informatics interoperability standards.

HL7 is an international community of healthcare subject matter experts and information scientists collaborating to create standards for the exchange, management and integration of electronic healthcare information.

HL7 promotes the use of such informatics standards within and among healthcare organizations to increase the effectiveness and efficiency of healthcare information delivery for the benefit of all.

HL7 is one of several American National Standards Institute accredited Standards Developing Organizations ( SDOs ) operating in the healthcare arena.

The HL7 version 3 standard has the aim to support all healthcare workflows.

The HL7 Version 3 Development Framework ( HDF ) is a continuously evolving process that seeks to develop specifications that facilitate interoperability between healthcare systems.

The HL7 RIM, vocabulary specifications, and model-driven process of analysis and design combine to make HL7 Version 3 one methodology for development of consensus-based standards for healthcare information system interoperability.

The HL7 version 3 messaging standard defines a series of electronic messages ( called interactions ) to support all healthcare workflows.

Australia was an early adopter of the HL7 V2. x standards, which are now used ubiquitously in Australian public and private healthcare organisations.

The American Recovery and Reinvestment Act of 2009 ( ARRA ) and Health Information Technology for Economic and Clinical Health Act ( HITECH ) legislation specified HL7 versions 2. 3. 1 and 2. 5. 1, and the HL7 Continuity of Care Document ( CCD ), as the healthcare standards to meet certain certification requirements.

HL7 and its members provide a framework ( and related standards ) for the exchange, integration, sharing, and retrieval of electronic health information.

HL7 was founded in 1987 to produce a standard for hospital information systems.

The first mutually published standard is ISO / HL7 21731: 2006 Health informatics — HL7 version 3 — Reference information model — Release 1.

* Structured Product Labeling ( SPL ) – the published information that accompanies a medicine, based on HL7 Version 3

Currently, HL7 ’ s v2. x messaging standard is supported by every major medical information systems vendor in the United States.

RIM expresses the data content needed in a specific clinical or administrative context and provides an explicit representation of the semantic and lexical connections that exist between the information carried in the fields of HL7 messages.

Notable HL7 implementations currently include Prince Edward Island's drug information system ( DIS ).

AORTA uses HL7 version 3 messages and documents as its core mechanism for information exchange.

HLH basic theme is to target health care information exchange and interoperability using HL7 version 3.

Its purpose is to encourage the use of HL7 for uniform implementation of this supplemental information.

* HL7, DICOM and other health care related information interchange standards use OIDs for globally unique identifiers for both individual information objects as well as References to code systems and data element dictionaries.

IHE Integration Profiles describe a clinical information need or workflow scenario and document how to use established standards ( e. g. HL7, DICOM, LOINC ...) to accomplish it.

In the field of Electronic health records there are a number of existing information models with overlaps in their scope which are difficult to manage, such as between HL7 V3 and SNOMED CT.
