Case report: Taiwan's experience in adopting IHE technical framework to integrate systems.

Though more and more hospitals adopt PACS in Taiwan, they all meet the same problem of system integration. The Integrating the Healthcare Enterprise (IHE) association proposes an integrated technical framework and process profiles to solve problems of heterogeneous system integration in medical environment for information sharing. Therefore, this paper reports the experience of a case hospital that successfully applied IHE framework to integrate its HIS, RIS and PACS in Taiwan. This paper indicates that using the IHE can help evaluate the integration ability of PACS vendors, enhance staff's ability, shorten the PACS implementation time, reduce the cost, and reserve system's expansibility. The case hospital was able to successfully implement it's PACS because of executive's full support, using the standard, and providing complete training to reduce user's resistance. This paper not only shares the experiences of IHE adoption of a case hospital but also summarizes key factors to implement PACS successfully. Again, this paper confirms that standard is helpful to integrate heterogeneous system.
