Typical healthcare organizations have many proprietary heterogeneous information systems that must exchange data reliably. Seamlessly sharing information among systems is complex. The widely adopted HL7 version 2 messaging standard has helped the process of systems integration. However, using the HL7 standard alone does not ensure system interoperability. The HL7 standard offers a wide range of options. Trading partners, without prior agreement, are not likely to implement options that are compatible. As a result, interoperability is stifled and organizations are left to employ their own ad hoc solutions. Conformance message profiles provide the solution to this problem. Message profiles define a standard template that provides a precise definition of the data exchanged between applications in a common format. Defining a set of message profiles for controlling message exchanges establishes a well defined communications interface among organizations and facilitates interoperability. We present a methodology based on message profiles for defining, implementing, and testing HL7 interfaces. We demonstrate how the use of message profiles improve system interoperability and present a collection of tools that we have developed to facilitate the use of message profiles.
