Closed System Transfer Devices (CSTDs) are specialized medical apparatus designed to ensure the safe handling of hazardous drugs by preventing their release into the environment and blocking the entry of contaminants during the preparation and administration of drugs. These devices are essential for protecting healthcare workers, particularly in oncology and other high-risk therapeutic areas, from exposure to harmful drug vapours, aerosols, and spills, ensuring a fully closed controlled system. Recommended by regulatory bodies such as NIOSH and USP , CSTDs are a vital component in promoting workplace safety in healthcare settings. These are available in various types and formats, compatible with diverse drug-delivery systems and designed to support both efficiency and safety in clinical workflows.

Rising hazardous drug use and occupational safety concerns drive CSTD adoption in healthcare
The increasing use of hazardous drugs, particularly antineoplastics in oncology and immunosuppressants in other therapeutic areas, is raising serious occupational health concerns. According to NIOSH, over 8 million US healthcare workers risk exposure to these drugs through dermal contact, inhalation, or accidental spills during compounding and administration. These exposures are associated with adverse effects, including infertility, miscarriages, and an increased risk of cancer.
CSTDs mechanically block the release of drug vapors and aerosols, preventing environmental contamination. According to study published by NIH, a longitudinal evaluation over eight months across multiple wards and pharmacy areas using CSTDs plus standard cleaning found surface contamination rates at just 6%, significantly lower than pre-implementation levels. These findings underscore that as hazardous drug use rises, hospitals and infusion centers are increasingly adopting CSTDs, not just as a regulatory requirement but as a proactive measure to safeguard their workforce from long-term exposure and contamination.
Leveraging NIOSH and USP standards to enhance CSTD usability, safety, and engineering controls
Significant technological advancements in the design and usability of CSTDs are being driven by evolving guidelines and testing protocols established by leading authorities such as NIOSH, and USP. NIOSH has developed a draft vapour-containment performance protocol that uses 2-phenoxyethanol (2-POE), a potential compound validated in studies, and highly sensitive analytical methods to evaluate how effectively CSTDs limit hazardous drug vapour release. With the growing awareness of the risk associated with exposure to hazardous drugs, more countries are adopting strict regulatory guidelines, like USP , to continue to reinforce the role of CSTDs as an added layer of protection during hazardous drug handling. These standardized test protocols have influenced manufacturers to enhance mechanical barrier designs, which have led to innovations such as needleless systems, intuitive locking mechanisms (like click-to-lock or color-to-color alignment), and user-friendly assembly, making CSTDs safer and more efficient.
Together, these guidelines have enhanced usability, safety features, and engineering controls across CSTD product lines, aligning device performance more closely with best-practice expectations for healthcare worker protection
