A computerized support system for checking prescriptions was developed in connection with the prescription order entry system already in operation at our institution. Drug interaction, drug duplication and contraindications for any prescriptions with overlapping administration periods can be checked by this system. The detected hazards are printed out on the prescription and the prescription-checking list on which medication histories are printed out. The pharmacist refers to the information from this system and then inspects the prescription. If the information from this system does not apply to the patient, the pharmacist can ignore this information. We established strict criteria for the prescriptions checking this system. In case that pharmacist suspects any potential problems and the physicians do not alter the prescription details, then the pharmacist registers such potential in this system. The registered information, which is printed on the prescription during the follow-up examination, prevents the pharmacist from continually finding the same problem.
After this system was introduced, the number of drug interactions and drug duplications decreased remarkably. we therefor find this system to be useful for the rational use of medication.
