Design and use of a joint order vocabulary knowledge representation tier in a multi-tier CPOE architecture.
Two major barriers to adoption of computerized physician order entry (CPOE) systems are the initial physician effort to learn the system and ongoing time costs to use the system. These barriers stem from the CPOE system's need to reformulate physician orders into services that can be electronically communicated to ancillary clinical systems such as pharmacy, nursing, lab or radiology as well as to billing systems. Typical CPOE systems use significant custom user interface programming to match the terms used by physicians to order services as well as the aggregation of those orders into order sets with the underlying orderable services. We describe the design and implementation of a commercial CPOE system that has a formal separate intermediate mapping layer to match physician screen vocabulary and ordering behaviors to underlying services, both individually and in groups, supported by powerful search tools.
