North America

Canada

Prince Edward Island, a province within Canada is the only instance of a province-wide attempt at implementing the HL7 interoperability standard. It has been standards compliant with the following characteristics of HL7:

• (CeRx) Messaging Standard (HL7 v3).
• Standards Collaborative through HL7 Canada.
• Set of 78 messages.
• Deemed “Stable for Use” in Canada (V01R04.2 + Addendum).

Mexico

The main user of HL7 in Mexico is the Mexican Institute for Social Security (IMSS). IMSS have been developing V3 messaging for three years and currently have 19 active messages across 9 domains with a further 24 messages currently in development. They are using a modified version of Veteran's VISTA in combination with middleware which transforms from VISTA's native V2 messages to V3 and vice versa. There is also a joint project in progress to develop an HL7 Gateway with Microsoft. It is envisaged that this project will enable systems to exchange HL7 messages with IMSS without concerning themselves with HL7 translation. HL7 Mexico has also been working to make government agencies such as the Ministry of Health aware of the importance of HL7 in exchanging healthcare information. As well as improving external links, HL7 Mexico has also been working to improve its internal processes and encourage new membership across the board.

United States

The HL7 standards development organisation is based in America and oversees the development of the HL7 standard. HL7 current work programme includes:

• HL7 Version 2 (including HL7 V2.1, HL7 V2.2, HL7 V2.3, HL7 V2.3.1, HL7 V2.4 and HL7 V2.5)

• electronic health record
• HL7 templates, vocabulary, XML for HL7 messages
• arden syntax
• HL7 clinical document architecture and HL7 clinical context management.

Asia

China

China has so far tested HL7 messaging standards in order to ensure interoperability. In the Guangdong province, government has gone as far as to mandate that developers of health information systems utilize the HL7 standard to transfer patient clinical information.

The Chinese Hospital Management Association (CHIMA) manages the role of the Basic Data Set Standards project, of which its working groups have accomplished 1976 data items, some of which reference the HL7 standard.

Turkey

In Turkey, the HL7 affiliate operates as an autonomous subgroup of the Turkish Medical Informatics Association (TURKMIA). Affiliate members are admitted once they have passed certain prerequisite studies.

HL7 Turkey has been focusing a good deal of effort in the past year on raising the country's awareness of HL7, with the result that HL7 is (unofficially) the standard for Turkish healthcare informatics projects. HL7 Turkey has worked closely with the Turkish Ministry of Health IT Department in order to insure that the following areas would benefit from the HL7 standard:

• National Health Information System (NHIS) components
• Hospital Information Systems
• Family Physician Information Systems.

United Kingdom

HL7 UK is the UK affiliate organisation to HL7, and was set up in January 2000. The mission of HL7 UK is entirely complementary with that of the parent HL7 organisation: HL7 UK sets out to:

• educate the UK healthcare community and healthcare information system developers about HL7 standards, and promote effective and consistent implementation of HL7 standards in the UK.
• identify and analyse UK healthcare business requirements for electronic communication of healthcare information.
• match UK national requirement with HL7 messages, and if necessary, identifying the need for UK specific messages, profiles and implementation guides.
• report to HL7 on any specific UK needs that are not met by existing HL7 standards.
• prototype and pilot with clinical and business validation.

HL7 UK seeks to identify HL7 standards that are applicable to UK healthcare without change and those that require adaptations or national implementation guidelines to meet UK requirements. Where UK adaptations, profiles or guidelines are required, HL7 UK proposes solutions that meet the need for consistent national implementation, while avoiding unnecessary divergence from HL7 standards. To this end, HL7 UK feeds back national requirements and proposed solutions to its parent body.

Switzerland

HL7 version 2 is used by almost all Swiss hospitals. Their HL7 v3 CDA implementation guide covers all documents needed to support the "hip replacement" clinical pathway. Parametrix, the biggest medical information system vendor in Switzerland has been using a RIM based architecture.

South America

Argentina

HL7 Argentina formed in 2000 with just five original members. Economic instability in the country meant that any expansion of the affiliate was virtually impossible until 2004, but they now have more than twenty members, consisting of an 80/20 membership split in terms of organization/private subscriptions. In terms of membership headcount, HL7 Argentina may be comparatively small but they are certainly very active. Diego Kaminker, recently elected chair of the affiliate, kindly shared with me some of the recent and ongoing HL7 developments with which his country has been involved. Currently, the largest HL7 implementation in Argentina can be found at the Hospital Italiano de Buenos Aires (HIBA).
