Health Level Seven (HL7®)


Health Level Seven (HL7®) is a American National Standards Institute accredited Standards Developing Organization (SDO) operating in the healthcare arena. Since its inception, HL7® has specified standards for a large number of application areas. HL7® standards cover generic application fields such as patient administration, patient care, order entry, results reporting, document and financial management. In addition to that, HL7® addresses the different clinical specialties like laboratory medicine, diagnostic imaging and clinical decision support.

Currently there are 3 active Product Families: V2 (Version2), CDA® (Clinical Document Architecture) and FHIR® (Fast Healthcare Interoperability Resources). Additionally, within FHIR®, HL7® provides a specification for context synchronization among applications called FHIRcast.

The HL7® Conformance Statements specify the details about the implementation of HL7® standards for specific products.
