Experimental assessment of the feasability of integrating an endoscopic imaging system into an existing hospital information system

The National Cheng Kung University (NCKU) Hospital operates a comprehensive integrated hospital information system. This was designed and installed as an integral component of the building of the hospital, which opened in 1988. The information system provides a service to all staff in the hospital, administrative and clinical, across the whole of the hospital. To make sure that the information is accessible, where and when it is needed, a comprehensive communications network consisting of both hardware and software mechanisms supports the information system. This paper explores the requirements for a computerised image system for endoscopy and assesses two approaches to the implementation of such a system, as a stand-alone system and as a subsystem of the NCKU hospital information system already in place. The latter would satisfy the original design specification of developing a single system to cover all aspects of hospital operation but places additional demands on the endoscopy systems designer to ensure integration. Both operational modes are set out in the paper and their implications assessed.
