Use of Controlled Vocabularies to Support Electronic Health Information Exchange

The goal of anywhere, anytime medical information exchange is impeded by the plethora of local conventions for identifying health data in separate electronic systems. Clinicians, administrators, and researchers all need a complete set of clinical information, coalesced from all of the various sources that produce health data. Mapping local terms to a standardized vocabulary such as LOINC bridges the many islands of health data that exists and facilitates data aggregation. But, mapping terms is a complex, labor-intensive process. The goal of this work is describe and understand the challenges and develop tools to overcome them.
