What is a Closed System Drug Transfer Device?

What is a Closed System Drug Transfer Device (CSTD) and Why Is It Critical for Healthcare Institutions?

In healthcare environments handling hazardous drugs, safety is not only a clinical concern but also a matter of occupational health, environmental protection and regulatory compliance. Cytotoxic and biologic agents used in oncology and chemotherapy require advanced protection systems to reduce exposure risks.

Closed System Drug Transfer Devices (CSTD) are mechanically engineered systems designed to prevent the escape of hazardous drugs in the form of aerosols, vapors or droplets during preparation, transfer and administration. At the same time, they prevent external contaminants from entering the system, providing dual protection.

Why Were CSTD Systems Developed?

Traditional open systems may generate microscopic leaks during drug compounding and transfer. This can lead to:

  • Chronic occupational exposure
  • Environmental contamination
  • Surface and air pollution
  • Long-term health risks for healthcare personnel

Organizations such as NIOSH and USP <800> recommend the use of closed systems when handling hazardous drugs.

Benefits of CSTD Technology

✔ Minimizes aerosol and droplet formation
✔ Reduces leakage risk
✔ Prevents environmental contamination
✔ Standardizes clinical workflows
✔ Supports compliance with international safety standards

In modern hospitals, CSTD implementation is no longer optional—it is becoming a safety benchmark.

Engineering-driven solutions such as AEGISELL integrate drug safety seamlessly into clinical practice, enhancing both protection and operational efficiency.
