We investigated the usefulness of a prescription checking system in risk management. At Gifu University Hospital, doctors prescribe medications using an order entry system or by writing out a prescription by hand. The ordering of prescriptions is checked by an order entry system when doctors make a prescription, and is checked by a dispensing support system at the time the drugs are dispensed. Regarding prescriptions ordered by this system and handwritten prescriptions prescribed from October, 2000 to April, 2001, the frequency that a prescription was correct was investigated.
The total number of prescription during the investigation period was 92, 624 sheets, and 973 prescriptions had to be corrected. The frequency that system ordered and handwritten prescriptions had to be corrected 0.9% and 6.5%, respectively. The frequency of correcting prescriptions ordered through the order entry system was significantly low. Drug duplication, drug interaction, and so on were corrected when ordering with this system, and some of them were checked by the prescription checking system. A mistake in the prescription, the prescription of non-registered medicines at our hospital, all had to be corrected for handwritten prescriptions, and 81% of such mistakes would have been avoided if they had been prescribed by the order entry system. Based on our findings, we consider our order entry system and prescription support system to effectively decrease the number of corrections needed when doctors make prescriptions.
