Examination of Actual Medical Material Cost and Cost Reduction Related to Exposure Prevention in the Preparation of Anticancer Drugs

: At Ogaki Municipal Hospital, we expanded the preparation of anticancer drugs using a closed system drug transfer device (CSTD)when revising medical fees in 2016. In this study, we investigated the number of regimens and number of preparations for outpatients in December 2017. Subsequently, the cost of all consumables related to the preparation of anticancer drugs was calculated. In total, 574 preparations of 68 regimens were conducted, with CSTD used in the preparation of 331 (57.7%)drugs. The cost associated with preparation of anticancer drugs was 1,608,163 yen/month, of which the CSTD cost was 1,135,315 yen/month(70.6%). Given the disproportionately high cost related to CSTD, we investigated for material cost reduction. Although CSTD has a mechanism for adjusting the differential pressure inside and outside the vial, the conditions were used to calculate medical fee; however, if we use what we do not have, we estimated that the facility burden would be reduced by 24.7%. CSTD can contribute not only to safety through exposure prevention but also to medical cost reduction through introduction of "Drug Vial Optimization." We believe it will continue to act as a medical evidence to reduce medical fee remuneration and ease the conditions of fee calculation.
