Closed System Drug Transfer Device

Closed System Drug Transfer Device (CSTD) is a type of medical device specifically designed to prevent the escape of hazardous drug substances into the environment during the preparation and administration of these drugs. CSTDs are primarily used in healthcare settings such as hospitals and pharmacies to protect healthcare workers from exposure to potentially harmful drugs, particularly antineoplastic drugs used in chemotherapy.

Overview

A Closed System Drug Transfer Device is a drug transfer device that mechanically prohibits the transfer of environmental contaminants into the system and the escape of hazardous drug or vapor concentrations outside the system. The use of CSTDs is recommended by various health and safety organizations, including the National Institute for Occupational Safety and Health (NIOSH), to protect healthcare workers from exposure to hazardous drugs.

Types of CSTDs

There are two main types of CSTDs: physical barrier systems and air cleaning systems.

• Physical barrier systems use a physical barrier to prevent the escape of drug vapors and aerosols during the drug transfer process. These systems typically include a drug vial adapter, a syringe adapter, and a bag or bottle adapter.

• Air cleaning systems use a filter to remove drug vapors and aerosols from the air inside the system. These systems typically include a drug vial adapter, a syringe adapter, and a bag or bottle adapter, as well as a filter.

Benefits of CSTDs

The primary benefit of using a Closed System Drug Transfer Device is the protection it provides to healthcare workers from exposure to hazardous drugs. Other benefits include:

• Reduction in drug waste
• Prevention of drug contamination
• Improved patient safety

Limitations and Challenges

While CSTDs offer significant benefits, they also have some limitations and challenges. These include:

• High cost of implementation
• Need for training and education
• Compatibility issues with certain drugs and vials
