Pre and post intervention study of antiblastic drugs contamination surface levels at a Pharmacy Department Compounding Area

Cette étude vise à démontrer que l’utilisation d’un système clos de transfert des médicaments en combinaison avec un processus de décontamination réduit la contamination des surfaces dans la zone de préparation de notre pharmacie.


Assuring healthcare workers security on Hazardous Drugs (HD) compounding is critical in healthcare settings. Our study aims to demonstrate that the use of a Close System drug Transfer Device (CSTD) PhaSeal™ added to a decontamination process reduces antiblastic surface contamination levels in the Compounding Area (CA) of our Pharmacy Department (PD).

We selected cyclophosphamide, 5-fluorouracil and iphosphamide to be evaluated. Testing was carried out with a wipe kit and quantified by an independent laboratory. We defined four sampling times: baseline; just after a decontamination procedure, which was repeated weekly during the study; four months after introduction of CSTD PhaSeal™ for cyclophosphamide and 5-fluorouracil compounding; and after eight months using CSTD PhaSeal™ for cyclophosphamide and 5-fluorouracil and one month for iphosphamide compounding.

There was a decrease at the number of positive samples at the beginning/end of the study for all the drugs tested: 28/15 for cyclophosphide, 29/23 for iphosphamide and 7/1 for 5-fluorouracile.

Comparing to the baseline, median cyclophosphamide levels significantly decreased (p-value <0.001) at 4 and 8 months sampling time (baseline: 1.01 ng/cm2 to 0.06 ng/cm2 and 0.01 ng/cm2), and median iphosphamide levels significantly decreased (p < 0.001) at 8 months sampling time (baseline: 3.02 ng/cm2 to 0.06 ng/cm2). 5-Fluorouracil did not show significant differences between the sampling times (baseline: 0.09 ng/cm2 to 0.09 ng/cm2).

We saw a significant increase at iphosphamide levels at 4 months sampling point, contrary to cyclophosphamide, which levels had decreased. The use of CSTD PhaSeal™ for iphosphamide compounding the last month was implemented for ethical reasons after this intermediate results review.

Our study suggests that the use of CSTD PhaSeal™, adding to decontaminating procedures, significantly reduces antiblastic drug surface levels at the CA of our PD.
