Summary: The Association for the Advancement of Medical Instrumentation (AAMI) released new guidance, AAMI CR513:2024, to update best practices for radiation sterilization validation and routine control of single-use systems in pharmaceutical and biopharmaceutical manufacturing.

Key Takeaways:

  • Updated Practices: AAMI’s new guidance offers streamlined approaches for radiation sterilization validation and control, addressing outdated practices in the industry.
  • Focus Areas: The guidance covers sterilization dose, sterile claim, dose application, risk assessment, and user verification for single-use systems.

The Association for the Advancement of Medical Instrumentation (AAMI) announced the release of a new guidance document that updates best practices for manufacturers of pharmaceuticals and biopharmaceuticals.

Addressing Outdated Practices

Currently, pharmaceutical and biopharmaceutical manufacturers often rely on outdated best practices related to radiation sterilization and routine control of large single-use systems, according to AAMI. The new industry guidance is designed to help streamline these processes.

New Guidance Overview

The new guidance outlines acceptable alternative approaches to radiation sterilization validation and routine control for single-use systems. It is a Consensus Report, a document type based on expert opinion that AAMI uses to provide quick and practical guidance on urgent issues.

AAMI CR513:2024; Guidance on radiation sterilization validation and routine control of single-use systems used for pharmaceutical and biopharmaceutical manufacturing was produced by the AAMI Radiation Sterilization Working Group, a diverse team of sterilization and sterile processing professionals, regulators, and scientists. The group is co-chaired by Niki Fidopiastis, director of microbiology for global laboratory services at Medtronic, and Kimberly Patton, sterilization staff engineer and auditor of the MedAccred Program at the Performance Review Institute.

Key Areas of Guidance

AAMI CR513:2024 provides guidance on:

  • Sterilization Dose: Addressing which products should be selected for testing and best practices for testing.
  • Sterile Claim: Providing guidance on estimating sterility assurance level and selecting sterile claims.
  • Dose Application: Including information on the proper delivery of a verification dose and sterility testing.
  • Risk Assessment: Establishing the components of risk assessment for single-use systems, considering each system’s needs.
  • User Verification: Focusing on how to independently verify the sterility assurance level of a single-use system.

According to Fidopiastis, AAMI CR513 is a much-needed stopgap, and its simplified approaches for validation and routine control of single-use systems will provide manufacturers with the clear guidance they need.

“The current practices as written for radiation sterilization validation and control testing can be difficult to implement for large, complicated single-use systems and are often cumbersome and can lead to contamination in the test vessels,” said Patton. “They are also overly conservative in some cases where large equipment might not come into contact with the patient.”
