Clinical messaging standards development organization Health Level Seven International will offer some of its domain analysis models and functional models, which are early processes integral to making standards, for free during a pilot project. It is the first time the organization has made such an offer.

A domain analysis model is the first step in creating an HL7 standard for a specific care or research environment. “The domain analysis process produces documentation describing the stakeholders, activities, interactions and information for a particular domain and serves as the source of requirements used in the design of HL7 standards,” according to the organization. The purpose of a domain analysis model is to understand what types of messages will be required in particular situations, says Don Lloyd, director of technical publications at HL7.

Functional models specify the functional requirements of an electronic health records system, according to HL7. This involves outlining the important features and functions of an EHR, including criteria to support medication history, clinical decision support, and privacy and security, among other functions.

The three standalone domain analysis models available via a no-cost license during the one-year pilot, all part of HL7 Version 3, are Cardiology: Acute Syndrome; Clinical Trials and Registration; and Analysis Model: Vital Records.

Available free functional models support child health, behavioral health, long-term care, clinical research, and records management and evidentiary support.

Both sets of models are available here. While free, a click-through license registration is required.
