Abstract
To study the cause for unreceived medicines, the relation between daily total numbers of prescriptions and unreceived medicines was investigated during October 1, to November 30, 1991. Numbers of the total prescriptions, unreceived medicines and final unreceived medicines were 43, 838, 297 and 19, respectively. Certain questionnaires and telephone contact trials against outpatients who did not receive the prescribed medicines were also performed. The questionnaires indicated that unreceived medicines which occurring in outpatients were caused by long waiting time for dispensing. Telephone contact trials reduced by approximately 70% numbers of final unreceived medicines, indicating that the trial is a means for reducing the unreceived medicines and noncompliance.
