Abstract
Sharing of patient information has become important as the need for enabling cooperation in consultation and the referencing of clinical data among multiple hospitals. Questionnaires on the sharing of clinical information were sent to 55 national hospitals. As for the result, the majority of the facilities surveyed (91.7%, 39 hospitals) want to be able to share the clinical data of each national hospital within the network. There were also some concerns and comments about potential security problems, the protection of personal information, and ethics considerations. In this research, in addition to reporting the results of this questionnaire investigation, we studied the environment of the hospital information system and the data infrastructure in national hospitals in order to realize clinical data sharing. For future study, the indicators for handling data and the guidelines for the secondary use of patient information are required. Furthermore, we think that a unification code among hospitals is indispensable for database standardization.
