外来における手術前服用薬調査業務の構築とその評価

抄録

To avoid postponement of surgery following hospital admission due to prior administration of antithrombotic drugs, beginning in 2002, we developed a system for surveying outpatients to determine all drugs taken by those scheduled for surgery. The system involves an expanded version of the preoperative drug administration survey previously conducted at the time of hospital admission, and we started using it for some outpatients scheduled for surgery. For the system, we prepared a list of drugs whose discontinuation should be considered prior to operations, software for inputting drugs discovered by the survey, and a pamphlet for distribution to patients, all of which made the operation of the system more effective. In 2003, 725 outpatients were subjected to the survey and the time required for each one to complete it was approximately 9 minutes. It showed that 5.1% of the outpatients were taking antithrombotic drugs, and with the assistance of pharmacists, administration was discontinued in 75 % of these patients. As a result, there was no postponement of surgery after hospital admission due to administration of antithrombotic drugs. Our survey allows all drugs being taken by outpatients to be determined at an early stage, including supplements and drugs prescribed by other hospitals, and it has thus been useful in preventing postponement of surgery after hospital admission.
