In generally, information on prescription orders that can be collected used in information analysis of oral medication. The University of Tokyo Hospital has been successfully operating oral drug administration ordering system for hospitalized patients that focuses on the medication process, resulting in reduced misreading/misunderstandings and errors in transmission of prescription and instructions. We analyzed the transaction log of our oral drug administration ordering system and clarified the present condition and problems of the oral medication process.
Hospitalized patients during the one-week study period were 5,004 person-days, analyzing information on 31,138 prescriptions, 32,370 medication instructions, and 51,385 medication implementation. 28% of the medication instructions uses the bringing medicine, and 30% is managed by the hospitalized patient himself. 30% of remaining drug count information was inaccurate. 14.1% of prescription medicine prescribed in the hospital was not administered according to the prescription order, and 26.9% of the implemented medication was not present in the prescription order history. Major drugs with such inconsistency were laxative and anticoagulant, and the major cause of inconsistency was classified as medical factors, operational factors, factors due to errors.
With our operation of the instruction and implementation system, it has become possible to analyze information according to the medication process, which was conventionally difficult to analyze prescription orders.
