| 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.
