CSTD (Closed System Transfer Devices)
A closed system drug transfer device or "CSTD" is a drug transfer device that mechanically prohibits the transfer of environmental contaminants into a system and the escape of hazardous drug or vapor concentrations outside the system. Open versus closed systems are commonly applied in medical devices to maintain the sterility of a fluid pathway. CSTDs work by preventing the uncontrolled inflow and outflow of contaminants and drugs, preserving the quality of solution to be infused into a patient. Theoretically, CSTDs should enable complete protection to healthcare workers in managing hazardous drugs, but possibly due to improper handling or incomplete product design, contaminants can still be detected despite use of CSTDs.

This study's aim was to determine how HD might spread through touch after handling contaminated vials in simulated pharmacy and nursing environments. Results show residue from HD vials spread as vial was handled in a pharmacy environment in 4 of 5 CSTDs, contaminating pharmacy PPE, ancillary products, and nursing PPE. No HD residue was detected on PPE, ancillary products, or nursing PPE in the pharmacy after using the SEVA system, providing an effective means to contain HD for drug transfer from vial to delivery system.

A Saudi Arabian study, published in May 2018, that sought to compare 3 CSTD’s (PhaSeal, Equashield II and ChemoLock) on their compounding efficiency and ease of use among pharmacy technicians and nurses to determine which product would be most suitable to adopt into their hospital protocol.

The purpose of this cost determination analysis is to appraise the direct and indirect costs of using a closed system transfer device (CSTD) to prevent occupational exposure to hazardous drugs. The data is from 2011, but is one of very few online resources about the cost of CSTDs. Barnachea L, Lee T, Gitler J. et al. Cost determination study of closed system transfer devices (CSTD).

The objective of this randomized, prospective and controlled study was to investigate the ability of a closed-system transfer device (CSTD; BD-Phaseal) to reduce the occupational exposure of two isolators to 10 cytotoxic drugs and compare to standard compounding devices. This study confirms that using a CSTD may significantly decrease the chemical contamination of barrier isolators compared to standard devices for some drugs, although it does not eliminate contamination totally.Simon N, Vasseur M, Pinturaud M, et al.

A study of leakage from selected closed-system transfer devices (ChemoClave,, OnGuard, PhaSeal) under experimental conditions is described.Nine manufacturer-trained oncology pharmacists and pharmacy technicians volunteered to participate in an experiment to determine the degree of leakage of a liquid test agent (a radioactive technetium isotope [(99m)Tc] diluted in normal saline) during CSTD-assisted transfer of liquid from vials to syringes per standard practices. The volume of leakage was significantly less with PhaSeal than with OnGuard and ChemoClave when pharmacists and pharmacy technicians used the three CSTDs and (99m)Tc as a tracer.
