The overdose and interaction of medication, combined with the high expenses of medicine, has become an important issue concerning the rational use of medication in health care. It is necessary to take preventive measures against irrational use of medication during medical treatment.<BR>The prescription order entry system for outpatients was started in July 1994 at Tokyo University Hospital. A decision-making support function (duplicate prescription check) was added to the system. In our study, we have investigated the prescription order entry database of our hospital information system from April 1996 to June 1996. According to the result of our investigation, duplicate prescription occurs most frequently with the Central Nervous System (CNS) drugs (8.6%) and the Circulatory System drugs (11.2%). The clinicians' opinion survey also indicated the high risk of duplicate prescriptions. Hence, a duplicate prescription warning system is needed . By comparing the occurrences of duplicate prescriptions before and after the system implementation, we found that for the Circulatory System drugs, the rates of duplicate occurrence before and after using the system were 11.2% and 5.1%, respectively, for the CNS drugs, the corresponding percentages were 8.6% and 4.6%, respectively . Therefore, the system clearly proved effective in helping reduce duplicate prescriptions.<BR>In the process of prescription order entry, we consider it crucial to provide physicians with relevant medicine information while they make treatment decisions . Such a support system will certainly help eliminate duplicate prescriptions and improve the quality of health care.
