HL7 is an international community of health care subject matter experts and information technology physicians and scientists collaborating to create standards for the exchange, management, and integration of protected electronic health care information. The Ann Arbor, Mich.-based Health Level Seven (HL7) standards developing organization has evolved Version 3 of its standard, which includes the Reference Information Model (RIM) and Data Type Specification (both ANSI standards).

HL7-3

The HL7 Version 3 is the only standard that specifically deals with creation of semantically interoperable health care information, essential to building the national infrastructure; HL7 promotes the use of standards within and among health care organizations to increase the effectiveness and efficiency of health care delivery for the benefit of all patients, payers, and third parties; uses an Open System Interconnection (OSI) and high level seven health care electronic communication protocol that is unique in the medical information management technology space and modeled after the International Standards Organization (ISO) and American National Standards Institute (ANSI); each has a particular health care domain such as pharmacy, medical devices, imaging, or insurance (claims processing) transactions. Health Level Seven’s domain is clinical and administrative data.

The Goals

Goals include:

  • develop coherent, extendible standards that permit structured, encoded health care information of the type required to support patient care, to be exchanged between computer applications while preserving meaning;
  • develop a formal methodology to support the creation of HL7 standards from the HL7 Reference Information Model (RIM);
  • educate the health care industry, policymakers, and the general public concerning the benefits of health care information standardization generally and HL7 standards specifically;
  • promote the use of HL7 standards world-wide through the creation of HL7 International Affiliate organizations, which participate in developing HL7 standards and which localize HL7 standards as required;
  • stimulate, encourage, and facilitate domain experts from health care industry stakeholder organizations to participate in HL7 to develop health care information standards in their area of expertise;
  • collaborate with other standards development organizations and national and international sanctioning bodies (e.g., ANSI and ISO) in both the health care and information infrastructure domains to promote the use of supportive and compatible standards; and
    • collaborate with health care information technology users to ensure that HL7 standards meet real-world requirements and that appropriate standards development efforts are initiated by HL7 to meet emergent requirements.

HL7 focuses on addressing immediate needs but the group dedicates its efforts to ensuring concurrence with other U.S. and International standards development activities. Argentina, Australia, Canada, China, Czech Republic, Finland, Germany, India, Japan, Korea, Lithuania, The Netherlands, New Zealand, Southern Africa, Switzerland, Taiwan, Turkey, and the United Kingdom are part of HL7 initiatives.
