We developed a reporting system for the identification of drugs brought to hospital by inpatients and introduced it at our hospital in April 2006.Using Microsoft® Access 2000,the system identifies drugs from the information input.It prints out reports on the results of identification,orders for re-dispensing medicines (pulverized drugs,one-dose package drugs,etc.) and management tables for the drugs.Our system also enables us to prepare information sheets on the relationship between drugs brought in by inpatients and drugs prescribed during hospitalization for patients who are to be discharged from hospital.Making such information available to physicians and nurses is an efficient way of avoiding the risk of drug interactions.The re-dispensing information provided enables us to make effective use of drugs brought in by inpatients.
