To improve healthcare service quality with balancing healthcare resources between large and
small hospitals, as well as reducing costs, each district health administration in Shanghai with more than 24 million citizens has built image-enabled electronic healthcare records (iEHR) system to share patient
medical records and encourage patients to visit small hospitals for initial evaluations and preliminary
diagnoses first, then go to large hospitals to have better specialists’ services. We implemented solution for
iEHR systems, based on the IHE XDS-I integration profile and installed the systems in more than 100
hospitals cross three districts in Shanghai and one city in Jiangsu Province in last few years. Here, we give operational results of these systems in these four districts and evaluated the performance of the
systems in servicing the regional collaborative imaging diagnosis.
