Abstract
A detailed analysis was performed on dispensing errors made by resident pharmacists in the initial step of practice training at the Osaka University Hospital Pharmacy during 1989.Based on the results, the education program was improved to prevent the dispensing errors as possible. The newly established program was effectively applied to the education of resident pharmacists in the pharmacy in the following year 1990: the dispensing errors 16.9% during the first week in 1989 was reduced to 10.9% in 1990.
