PACS/information systems interoperability using Enterprise Communication Framework

Interoperability among healthcare applications goes beyond connectivity to allow components to exchange structured information and work together in a predictable, coordinated fashion. To facilitate building an interoperability infrastructure, an Enterprise Communication Framework (ECF) was developed by the members of the Andover Working Group for Healthcare Interoperability (AWG-OHI). The ECF consists of four models: Use Case Model, Domain Information Model (DIM), Interaction Model and Message Model. To realize this framework, a software component called the Enterprise Communicator (EC) is used. We demonstrate the use of the framework in interoperating a picture archiving and communication system (PACS) with a radiology information system (RIS).

Using Gene Ontology to Generate Biological Contexts for Augmenting Statistical Patterns of Molecular Data

This paper describes the research to reduce high false positive discovery rates when discovering possible molecular diagnostic patterns. This effort combines information from the gene ontology with multiple sets of discriminating patterns discovered in a publicly available gene expression dataset on breast cancer. Using a second validation dataset, we identify candidate patterns with good and poor validation performance, and then show that certain biological contexts appear to provide some ability to discriminate between them.

Enterprise communication framework as a means to PACS/information systems interoperability

Interoperability among healthcare applications goes beyond connectivity to allow components to exchange structured information, and to work together in a predictable, coordinated fashion. To facilitate building an interoperability infrastructure an Enterprise Communication Framework (ECF) was developed by the members of the Andover Working Group for Healthcare Interoperability. The ECF consists of four models, (1) the use case model, (2) the domain information model, (3) the interaction model, and (4) the message model. To realize this framework, a software component called the enterprise communicator is used. In this paper we will demonstrate the use of the framework in interoperating a PACS with a radiology information system.
