The Association for the Advancement of Medical Instrumentation (AAMI) generates numerous standards and guidelines used by professionals in the healthcare industry. Occasionally, the AAMI Standards board will provide additional guidance to specific standards in the form of a Technical Information Report (TIR). These TIRs reflect common industry practices that evolve from an accumulated process knowledge base.
In the last few years many changes have occurred to the guidance documents we have all followed to set minimum sterilization doses. With the completion of ANSI/AAMI/ISO 11137:2006 and the addition of AAMI TIR 33, many options were placed in the hands of the healthcare industry. Significant changes such as bringing VDmax 25 into an ISO document, the additional of a VDmax 15 option and incorporation of single lot validation for Method 1 have eliminated or reduced the need to use older AAMI or AAMI/ISO documents like TIR 27, 15844 and 13409 but have made the familiarity with the current ANSI/AAMI/ISO documents even more critical to the needs of the healthcare industry.
While this document is not intended to be an exhaustive comparison of old versus new guidelines, we wanted to bring together to a chart format, a comparison of the steps for dose audits as starting point when preparing to review these documents for the first time as they apply to your specific product needs or requirements. This document does not replace the need to assure that you are compliant and current with all regulatory requirements specific to your product. This TechTip will look at dose auditing, while a companion document will look at dose setting in this same format.

Overview of an E-Beam Irradiation Validation For Healthcare Products
Prior to beginning routine processing with electron beam (E-beam) irradiation, a product with a sterile claim needs to complete a validation process to ensure the sterility assurance level claimed is achieved.
