Abstract
Health data interoperability issues limit the expected benefits of Electronic
Health Record (EHR) systems. Ideally, the medical history of a patient is recorded
in a set of digital continuity of care documents which are securely available to the
patient and their care providers on demand. The history of electronic health data
standards includes multiple standards organizations, differing goals, and ongoing
efforts to reconcile the various specifications. Existing standards define a format
that is too complex for exchanging health data effectively. We propose hData, a
simple XML-based framework to describe health information. hData addresses the
complexities of the current HL7 Clinical Document Architecture (CDA). hData is an
XML design that can be completely validated by modern XML editors and is explicitly
designed for extensibility to address future health information exchange needs.
hData applies established best practices for XML document architectures to the
health domain, thereby facilitating interoperability, increasing software developer
productivity, and thus reducing the cost for creating and maintaining EHR
technologies.
