Objective: To develop a module for the prevention of drug-related allergies to be integrated within the assisted electronic prescription software PRISMA.
Method: On module design potential sources of medication errors regarding drug allergies were first analyzed, and ideal module characteristics were defined. Then a review of the literature was performed to define "group allergies", and last of all master archives were created, with their required relations being established.
Results: A module for the prevention of drug-related allergies in the setting of an assisted electronic prescription software was designed. By interrelating tables listing active ingredients, excipients, chemical structures/functional groups, and "group allergies" prescriptions may be interactively checked, and useful information is provided to the prescribing practitioner--as well as the whole multidisciplinary team--to help him make his/her decisions.
