Abstract
Integrated Healthcare Enterprise (IHE) provides a framework to ease the integration of, and information flow between, various medical information systems in a healthcare enterprise. IHE’s scheduled workflow integration profile describes the transactions and actors involved in maintaining information flow between ordering system, scheduling system and image acquisition system. It thereby facilitates film-less transactions between RIS/ HIS and PACS. Order filler is a key actor for realizing scheduled workflow integration profile. It acts as a gateway between order placer, modality and performed procedure step manager by converting HL7 to equivalent DICOM messages and vice versa whenever required.

This white paper considers the scheduled workflow IHE integration profile, in order to demonstrate the methodology for integrating the HIS and PACS/Modality. The paper also talks about the desirable characteristics of the architecture for the implementation of order filler, the key component for implementing scheduled workflow integration profile. The proposed solution with multi-platform support would be distributable, scalable, and configurable. It would typically reside on the PACS side and can be used to IHE-enable (SWF profile) a PACS with any HIS/RIS solution. The paper also goes on to propose a five-step process to integrate RIS-HIS-PACS systems for a healthcare enterprise.
