The clinical pharmacy services provided by the satellite pharmacy to our hematological tumor unit include the mixing of injection drugs,making inquiries concerning injection drug prescriptions on the basis of medication history management and checking chemotherapy regimens.We investigated whether such services were useful in enhancing medical safety through a questionnaire survey of nurses in the hematological tumor unit.The results showed that the injection drug mixing service provided by pharmacists reduced the time that nurses took to mix injections by 50% as compared with before the service was introduced.Further,after the satellite pharmacy opened,the number of pharmacist inquiries addressed to physicians concerning doubtful prescriptions increased markedly,and the percentage of prescriptions which were changed due to doubtful content also increased greatly.As a result,the frequency of errors in medications decreased significantly.The findings of this study showed that clinical pharmacy services provided to the hematological tumor unit contributed to improving medical safety.
