2007 IHE Eye Care Connectathon Results On October 8-11, the IHE Eye Care convened a 4 day Connectathon, a face-to-face interoperability testing event based on the IHE Eye Care Technical Framework Year 2. The purpose of the Connectathon was to test implementation of the IHE capabilities in commercially available systems. This was a requirement for participation in The Electronic Office, the Interoperability Showcase at the AAO 2007 Annual Meeting. The testing process provided a unique opportunity for vendors to test the IHE integration capabilities implemented in their systems with each other in a neutral forum sponsored by IHE Eye Care, managed by IHE Eye Care project managers, and hosted by the Radiological Society of North America. The IHE Technical Framework defines a subset of the functional components of the healthcare enterprise, called IHE Actors, and specifies their interactions in terms of a set of coordinated, standards-based transactions. These transactions are organized into functional units called Integration Profiles that highlight their capacity to address specific clinical needs. Three separate profiles, which represent different integration problems, were used in the testing process: Eye Care Workflow, Charge Posting and Eye Care Evidence Document. The Eye Care Workflow Integration Profile deals with the coordination and exchange of information of the following tasks that are part of every patient visit: admit or register patients, order tests/images for patient, schedule procedures, create a worklist (or list of procedures that were ordered), monitor the status of procedures performed, create images, manage or keep track of images created, store images and display images. The Charge Posting Profile provides a solution for collecting and posting timely billable procedural details. The Evidence Document Profile is intended for the incorporation of additional measurements and observations as documents: creating, storing, retrieving and using these different documents as a record of evidence. The following companies participated: Carl Zeiss Meditec, Inc., Compulink Business Systems, Heidelberg Engineering, ifa Systems, Kowa, Medflow, Inc., MDoffice, Nidek, Ophthalmic Imaging Systems, Inc., Ophthalmic Technologies, Inc., Topcon Medical Systems, Inc., and VersaSuite. During the 4 days of testing, these vendors with 15 different systems, executed 115 peerto-peer tests under the supervision of the Connectathon monitors. This included 1 day of full workflow testing where all the vendors participated to demonstrate end-to-end integration, from patient registration and ordering, through image acquisition, storage and display, and to automatic posting of charges based on the procedures performed. These vendors tested for their different roles/actors. The charts below can be used as an aid to determine what level of integration this product supports with other systems and what benefits such integration might provide. Not all tests for each configuration were


able to be completed at the IHE Eye Care Connectathon. Potential purchasers should also refer to the individual vendors’ IHE Integration Statements and DICOM conformance statements to see exactly what software versions are able to be integrated and for additional details.
