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

Informatisation of drug prescription is an important topic in medical infor matics. For several years now, computerized drug databases have been implem ented. Usually only a small part of the prescriptions can be stored in pres cription systems because of the format of the included information; prescri ptions 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 comp uterized drug prescription system, The model should be applicable to clinic al practice and be didactic for medical students, The problem of standardiz ation of terminology had to be solved. A computer-assisted drug prescriptio n program has been developed. The next step is its validation by clinicians . The program can also be used in a consultation mode.
