[Selection of a hospital information system--experiences and critical aspects].
Due to typical problems (heterogeneity, lack of clinical functionality, Y2K problems) the board of directors of the university hospital of Marburg decided in 1997 to replace major components of the existing system by commercially available software. The products available on the market were analyzed, and, under participation of different user groups, a comprehensive functional specification was generated. This was the basis for a Europe-wide vendor selection process. In this context, several key aspects were identified, which are critically important for realizing a HIS that fulfills the specified functional requirements. Among these key aspects are the integration of heterogeneous system components, the support of cross-departmental workflow, and flexibility as well as adaptability to specific clinical requirements. As a result, we found that with today's commercially available products and standards there is no single solution that fully meets all requirements. However, some "generalist" vendors are offering integrated systems with acceptable clinical functionality. Tools are emerging which enable the clinical user to generate forms for data input and data flow. Still, a hospital information system will consist of separate components that have to be integrated, but the role of integrated, component-based approaches is becoming more important.
