A computer-assisted drug prescription system: The model and its implementation in the ATM knowledge base

Abstract

Informatisation of drug prescription is an important topic in medical informatics. For several years now, computerized drug databases have been implemented. Usually only a small part of the prescriptions can be stored in prescription systems because of the format of the included information; prescriptions contain essentially free text without any structure and homogeneity of the used vocabulary. In this article a model is presented for knowledge representation in a computerized drug prescription system. The model should be applicable to clinical practice and be didactic for medical students. The problem of standardization of terminology had to be solved. A computer-assisted drug prescription program has been developed. The next step is its validation by clinicians. The program can also be used in a consultation mode.
