title: Design of a computerized system for the retrospective analysis by the physician of his own drug prescriptions.
abstract: The quality of drug prescription is known to be poor in many medical domains. Feedback information may help the physician to improve this component of his medical activity. The increasing use of computerized drug prescription systems makes possible the retrospective processing of prescriptions made over a given time period. This paper describes the design of a computerized system for providing feedback information to the physician about the quality of his drug prescribing activity. It is designed to be used by the physician himself. The analysis is based on two groups of quantitative indicators, simple and composite. The constraints that must be satisfied to calculate these indices automatically are given. They are related to the coding systems used for drug prescription, knowledge on drugs and patient data. The system design is based on modeling according to UML formalism. We give also a concrete view of the main functions of the system, based on a pictorial illustration with a component of the user interface. Some limitations and the possible extensions of this system for analyzing simultaneously the prescriptions made by set of physicians are discussed.
