Version 3 Standard 'Patient Administration' Approved
Health Level Seven (HL7) Recently Announced that Version 3 Standard: Patient Administration, Release 1 Has Passed the Ballot Stage and has Been Approved as a Draft Standard for Trial Use (DSTU)
Ann Arbor, Michigan, USA. April 27, 2004.
Health Level Seven (HL7) recently announced that Version 3 Standard: Patient Administration, Release 1 has passed the ballot stage and has been approved as a Draft Standard for Trial Use (DSTU). "This document is the result of five cycles of committee ballots and uncounted hours of thought by many HL7 members," said Gregg Seppala, co-chair of HL7's Patient Administration Technical Committee and contributing editor of the standard.
Patient Administration, also known as ADT (Application, Discharge and Transfer), supports many of the core administrative functions in healthcare, such as person and patient registration and encounter management.
"The challenge faced by the Patient Administration Technical Committee (TC) in rewriting Patient Administration for Version 3 was to redefine messages for a domain that has been an essential part of HL7 since the very first draft of the standard was presented in 1987," Seppala said. "After our initial analysis identified nearly 460 possible messaging events, the technical committee chose to approach writing the V3 standard incrementally."
According to Seppala, Release 1 supports 53 of the most common messaging events such as: "add a new patient," "revise demographic information about a person," and "admit an inpatient."
"We hope that Version 3 early adopters will apply our DSTU and provide feedback to guide our work on release 2," he said.
The Patient Administration domain defines person and patient demographics and visit information about patients. Generally, information is entered into a Patient or Person Registry or into a Patient Administration system and passed to other systems (e.g., other registries, clinical, ancillary and financial systems).
The V3 Patient Administration Standard is being published for a twelve-month period of trial use. It is one of over two dozen specifications that together make up the Version 3 Messaging Standard. The V3 project represents a new approach to clinical information exchange. It is XML-based and built from the ground up around a single object model, the HL7 Reference Information Model (RIM), and a rigorous methodology that ties model to message and finally to syntax.
The V3 specification is built around subject domains, for each of which it provides storyboard descriptions, trigger events, interaction designs, domain object models derived from the RIM, hierarchical message descriptors (HMDs) and a prose description of each element. Implementation of these domains further depends upon a non-normative V3 Guide and normative specifications for: data types; the XML implementable technical specifications (ITS) or message wire format; message and control "wrappers"; and transport protocols.
