Centralization impact and cost-saving study in a Moroccan hospital's centralized unit of chemotherapy preparation

The purpose of this study was to assess the cost saved and the amount of drug wasted when compounding anticancer drugs in the centralized unit for chemotherapy preparation. A secondary objective was to estimate the centralization impact of activities related to the preparation of chemotherapies.

This was a two-month, single-centre, prospective study conducted at the National Oncology Institute in Rabat. The cost saved and the amount of drug wasted were calculated using a standardized data collection sheet (the prescribed dose, the amount of drug deployed, the amount remaining after compounding, the amount of drug saved and the drug wastage). The centralization impact was calculated using the amount of drug wasted in the centralized unit for chemotherapy preparation and a theoretical amount of drug wasted without centralization of preparation.

During the study period, the total amount of drug saved was 249,959.5 mg (7.2% of drug used), which represented 96,657 USD. The amount of drug wasted was 89,290.5 mg or 42275.5 USD. The drug waste per dilution and per drug was 6.4 mg [1.6-16.1]. While the potential savings over one year (580,000 USD) reached 13.9% of the cytostatic drugs budget for 2018, the potential drug waste cost reached 6.1%. The centralization impact is estimated at an average of 79.5% ± 13.7% waste reduction.

The outcome of our study showed that the grouping of prescriptions in centralized unit for chemotherapy preparation could result in significant savings on the amount of drugs deployed. The centralization of cytostatic preparations is of economic interest.
