Abstract

Closed-system transfer devices enhance the drug handlers’ protection against hazardous drugs exposure by prohibiting the escape of liquid or vapor from the system. PhaSeal (Becton Dickinson), a reference closed-system transfer device, includes a vial protector with an expansion chamber, and an injector with an enclosed needle. VialShield (CareFusion) is another more recent closed-system transfer device including an expansion chamber and a non-return valve, designed to be used in association with Texium (CareFusion), a closed, needlefree male luer with its preassembled syringe. Evaluation of VialShield/Texium was done comparatively to a classic spike device (Spike Swan, Codan) and PhaSeal. Evaluation methods consisted in practical evaluation by pharmacy technicians (evaluation of ease to use by nine operators in practical conditions during a complete week of production), microbiological safety performance (by Media Fill Test), and leakage assessment (fluorescein, titanium tetrachloride smoke, and radioactive tracer). Results showed that 100% of those operators evaluated would be ready to use VialShield/Texium for daily use, whereas only 75% of them would be ready to use PhaSeal. The use of PhaSeal and VialShield/Texium increased the duration of preparations compared to Spike Swan. No microbiological growth was observed with any of the three devices. A leakage of smoke was observed only with Spike Swan. Fluorescein leakage assessment confirmed that PhaSeal is a performing closed system with a dry connection. Spike Swan showed fluorescein leaks. Fluorescein drops were visible on the connection sites of the VialShield/Texium. Nevertheless, no fluorescein was found on compress after connections swapping. Transfer performance, assessed using technetium-99m, was 98.1 ± 1.4%, 97.9 ± 1.1% and 97.0 ± 1.3% and dead volume of the devices, were 1.0 ± 0.8%, 1.7 ± 0.6%, and 3.0 ± 1.1% for Spike Swan, PhaSeal, and VialShield/Texium, respectively. VialShield/Texium appeared as a very interesting device with performances close to PhaSeal (except dry connection), with a higher satisfaction assessment from the operators.
