The objective of this study was to examine a design for a World Wide Web-based decision-support system in use by clinically active physicians. A prototype implementation of the design concerned management of infective endocarditis patient cases. The design was based on an integration of hypertext and rule-based knowledge. In the study sessions, physicians in the field of internal medicine worked on managing authentic patient cases in a laboratory setting. Data was collected from interviews with the physicians using video recordings and stimulated recall technique. The qualitative data was analysed according to the constant comparative method in order to develop a model of the physicians' usage of the system. The resulting model describes perceived contributions and criteria for usefulness of the system. The ways the physicians used the system showed that it was able to provide patient-specific support for confirming clinical decisions, for higher-level patient management, and for preparing for and initiating expert consultations. Users also stated that new medical knowledge could be gained as a side effect of using the system.

“…The integration makes it possible to incorporate rule-based knowledge in the hypertext knowledge base (KB) and to provide extended explanations to the advice produced by the inference engine. As pointed out by Erdman [10], the possibility for DSSs to give explanations is crucial for the impact of such systems. The kind of support offered by the system may, for example, be interpretation and validation of laboratory results, or decision support regarding treatment in relation to local, national and international guidelines and expert opinions.…”

“…To assist health-care providers in an appropriate way, DSSs ought to be able to provide explanations regarding the given advice. The aim of giving explanations is to support the user in verifying the correctness of the given advice [10]. The explanations may also help clinici-ans foresee the consequences of their actions.…”

Abstract:There is an obvious need for geographic distribution of expert knowledge among several health care units without increasing the cost of on-site expertise in locations where health care is provided. This paper describes the design of a knowledge-based decision-support system for extended consultation in clinical medicine. The system is based on Arden Syntax for Medical Logic Modules and hypertext using World Wide Web technology. It provides advice and explanations regarding the given advice. The explanations are presented in a hypertext format allowing the user to browse related information and to verify the relevance of the given advice. The system is intended to be used in a closed local network. With special precautions regarding issues of safety and patient security, the system can be used over wider areas such as in rural medicine. A prototype has been developed in the field of clinical microbiology and infectious diseases regarding infective endocarditis.
