" HL7 " also refers to some of the specific standards created by the organization ( e. g., HL7 v2. x, v3. 0, HL7 RIM ).

HL7 develops conceptual standards ( e. g., HL7 RIM ), document standards ( e. g., HL7 CDA ), application standards ( e. g., HL7 CCOW ), and messaging standards ( e. g., HL7 v2. x and v3. 0 ).

HL7 v2. x has allowed for the interoperability between electronic Patient Administration Systems ( PAS ), Electronic Practice Management ( EPM ) systems, Laboratory Information Systems ( LIS ), Dietary, Pharmacy and Billing systems as well as Electronic Medical Record ( EMR ) or Electronic Health Record ( EHR ) systems.

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

These data are sent from HIS to RIS via integration interface, in most of hospital, via HL7 protocol.

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

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

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.

* Health Level Seven, Inc. ( HL7, Inc. ) is headquartered in Ann Arbor, Michigan.

* HL7 affiliate organizations, not-for-profit organizations incorporated in local jurisdictions, exist in over 40 countries.

The organizational structure of HL7 Inc. is as follows:

The Working Group is responsible for defining the HL7 standard protocol and is composed of Standing Administrative Committees and Working Groups.

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

HL7, Inc. is a standards organization that was accredited in 1994 by the American National Standards Institute ( ANSI ).

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

Today, HL7 has been adopted by several national SDOs outside the United States.

However, HL7 is now adopted by ISO as a centre of gravity in international standardization and accredited as a partnering organization for mutual issuing of standards.

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

RIM is the representation of the HL7 clinical data ( domains ) and the life cycle of messages or groups of messages.

HL7 version 2 defines a series of electronic messages to support administrative, logistical, financial as well as clinical processes.

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.

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

HL7 v3 messages are based on an XML encoding syntax.

The Social Insurance Institution of Finland is building a national ePrescribing and patient record archival service based on HL7 CDA R2 and V3 messages.

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

This SIG coordinates industry input to produce and maintain guides for HL7 messages that can stand alone or be embedded within ANSI X12 transactions.

* HL7 – messages format for interchange between different record systems and practice management systems.

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.

HL7 International currently asserts that business use of the HL7 standards requires a paid organizational membership in HL7, Inc. HL7 Members can access standards for free, and non-members can buy the standards from HL7, ANSI, or for some standards, ISO.

Almost all hospitals use HL7 version 2 to support hospital-internal workflows.

Though the penetration and use of HL7 in Pakistan is lower than the countries like US and that of Europe.

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.

A large portion of HL7 messaging is transported by Minimal Lower Layer Protocol ( MLLP ), also known as Lower Layer Protocol ( LLP ).

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.

Health Level Seven ( HL7 ), a standards-developing organization in the area of electronic health care data exchange, is an assigning authority at the 2. 16. 840. 1. 113883 ( joint-iso-itu-t. country. us. organization. hl7 ) node.

The HL7 Clinical Document Architecture ( CDA ) is an XML-based markup standard intended to specify the encoding, structure and semantics of clinical documents for exchange.
