Anticancer drug waste minimization and cost-saving study by using a closed-system transfer device for chemotherapy compounding

Abstract

Introduction There is a need for an economic evaluation of the use of closed system (CSTD) in chemotherapy compounding, especially in resource-constrained settings. Objective The objective of this study was to assess the cost saving of the management of cancer drug leftovers before and after introduction of CSTD associated with an extension of the beyond-use date (BUD) of cancer vials. A secondary objective was to estimate the level of minimization of drug wastage. Materials and methods This was a prospective, single-center study with two periods of two months each. The cost of drugs saved by using conventional systems (syringe and needle) without a closed system in the first period was compared to the cost of drugs saved by using the CSTD Chemoclave® system in the second period. The drug waste minimization rate compared actual drug waste to potential waste in Period 2. Results In Period 1, the amount of drug saved accounted for an average of 10.3% of the amount used in milligrams and the amount of drug wasted accounted for an average of 18.7%. In period 2, these proportions were 15.2% and 6.4% respectively. The CSTD generated an extra cost of 11,962.5 USD compared to the conventional system. The drug saved cost related only to the CSTD and the acquisition cost of the CSTD was a deficit of -7,444.95 USD and the cost saved from the compounding (CSTD and syringes) was a gain of 1,722.01 USD. The waste minimization represented an average of 72.5% ± 24.4% of potential waste. Conclusion The use of CSTD to extend the BUD allowed to reduce waste due to microbiological instability without adding an economic profit.

“…Exposure of ADs in the preparation department can be further reduced by implementing closed system drug transfer devices (Sessink et al 2011). Their use was also shown to reduce drug losses (Adade et al 2021). In contrast, nurses applying chemotherapy and other healthcare staff do not work in controlled areas; they commonly use only medical gloves that provide a generally lower level of protection.…”
