Abstract
Mistakes in filling prescriptions at outside pharmacies can sometimes lead to hospitalization, especially in the case of children. To counter this problem, we began to issue a “drug-record poketbook” to provide information to pharmacies and to educate the parents. We developed a system for drug management guidance in pediatrics aimed at improving the quality of guidance for medication. This system makes use of TDM, allows the participation in doctors' rounds, and provides pamphlets explaining certain points that the potients need to be careful about. After the introduction of this system, the number of dispensing errors at pharmacies decreased. This comprehensive information system enabled the monitoring of both inpatients as well as outpatients. These results show this system is a useful contribution to the service for patients.
