User-views in Health Care Information Systems

Database systems for the management of patient folders collect medical information pertinent to several users, physicians and others health care professionals, taking part cooperatively in the process of patient's care. These users have distinct roles in the clinical scenario and perform different kinds of working activities, that lead to diverse needs concerning patient data retrieval, visualization and processing. Data organization in patient folders has been object of study for decades, but no optimal solution has been found that can satisfy the requirements of all the users involved. In such a context, database management systems built on the base of a unique physical storage of information, but providing different perspectives on patients' data, are promising solutions. In this talk we present the methodology we adopted and the results we obtained in designing and developing an object-oriented database system providing technical solutions to important requirements of most clinical information systems:

Remote data access for authorized users is another considered aspect. As clinical application, we describe here the prototype of a user-oriented clinical information system for the archiving and the management of multimedia and temporally oriented clinical data related to PTCA (Percutaneous Transluminal Coronary Angioplasty) patients. Some suitable view schemas for various user roles (cath-lab physician, ward nurse, general practitioner) have been modeled and implemented on the base of the results of a detailed analysis of the considered clinical environment, carried out using an object-oriented approach previously developed in the field of business process modeling.
