A hospital medication monitoring system

Hospitals need to process large quantities of scattered information to properly screen medication orders. The data includes complex relationships involving drugs, diseases, and other drugs that determine whether a particular drug is contraindicated for a patient. Hospitals would therefore benefit from a flexible system for storing complex medical data relationships. We have used GPLAN, a CODASYL-like data management system, to construct a functioning model of a hospital pharmacy medication monitoring system. the patients' histories, drug-drug contraindications, disease-drug contraindications, and recommended dosages are stored in the data base in a network structure defined by the Data Description Language. Each drug order is checked for dose, allergies, current diseases, and current medications.
