Standards development can take three or more years before adoption for use. The purpose of this paper is to describe the analysis portion in the development of an HL7 V3 standard. The International Health Terminology Standards Development Organisation (IHTSDO), which owns and maintains SNOMED CT, and the HL7 Anesthesia working groups along with a senior informaticist at Duke University have begun such an analysis by using a Domain Analysis Model (DAM). A DAM and its artifacts or deliverables are the products of the Domain Analysis Process as described in the HL7 Health Development Framework (HDF). The HDF is a framework of modeling and administrative processes, policies and deliverables used by HL7 to produce specifications for a proposed standard. The project’s intent is the creation of a new standard for Preoperative Anesthesia Assessment Terminology with metadata for terms as appropriate in SNOMED CT and HL7 V3.
