Organizing patient data for use in clinical pharmacy practice and education.

A simple, low-cost manual data retrieval system, which provides selective access to all patient cases monitored by pharmacists, is described. The system uses notched cards which are coded by clinical descriptors. The codes are based on a modification of the International Calssification of Diseases, Adapted, disease-diagnosis coding system. This multiple entry system is flexible and can be easily converted to a computer-based system.
