WRITTEN AGREEMENT BETWEEN PRODUCT

MANUFACTURER AND CONTRACT STERILIZER


TECHNICAL TIP #15
The Association for the Advancement for Medical Instrumentation
(AAMI) provides several guidance documents to augment ANSI/
AAMI/ISO 111351, Validation and routine control of ethylene
oxide sterilization. One such document is AAMI TIR No. 14 20092, Contract Sterilization Using Ethylene Oxide. Within this
document, much attention is given to the written agreement
established between a product manufacturer and a contract
sterilization supplier. The following is a summary of the
information presented in the TIR.
Before starting contract sterilization processing, a written
agreement that outlines the services to be provided by both
parties should be developed and approved. Requirements for the
agreement between two parties are found in 21 Code of Federal
Regulation 801.150(e)3. This section of the regulations requires a
written contract when interstate shipping is involved. For
intrastate services, a contract is recommended to ensure
compliance with the GMP requirements for device master
records (21 CFR 820.181)4. The regulation specifies the contents
of the agreement, including a requirement for a detailed
delineation of the sterilization process. It is necessary to examine
the contract sterilizers compliance with this regulation. In
addition to the requirements of 21 CFR 801.150, good business
practices may require other inclusions in the written agreement to
clarify the division of responsibilities.

Process Validation
The written agreement should specify all parameters to be
qualified by the contractor and the criteria for re-qualification.
Loading Configuration
The agreement should specify the pallet patterns, vessel loading
configuration, packaging, and whether the load is pre-wrapped or
shrink-wrapped for each product or product family.
Biological Indicators and Product Test Samples
The agreement should specify responsibility for placement,
retrieval, handling, processing, and maximum time intervals
before shipment of BIs and product test samples. It should
include instructions for packaging and shipment of BIs and
product test samples to test laboratories for analysis.
Cycle Parameters and Process Control
The agreement should specify the process parameters and the
allowable limits that should be achieved for sterilization once the
sterilization process has been validated.
Post-sterilization Handling
The agreement should specify procedures for post-sterilization
quarantine of the product before release for distribution.

The written agreement may be in the form of a formal business


contract or in the form of internal Standard Operating Procedures
(SOPs) that are signed by both parties. The written agreement
shall, directly or by reference to existing documents, indicate the
responsibilities of each party for assuring the completion of all
GMP requirements related to the sterilization process. For
ethylene oxide sterilization, the written agreement should contain
or reference the following:

Batch Records and Review

Information Transfer

Audits

The agreement should specify the individuals at each facility


responsible for coordinating the flow of information between
establishments and for approving procedural changes.

The agreement should specify the scope of audits, corrective


actions, documentation or audit, and confidentiality.

Documentation
The agreement should specify all required documentation (for
example: procedures, processing records) to be used and
maintained. Both parties should agree on the manner in which
documentation changes are to be made.

The agreement should specify procedures and responsibility for


approving sterilization batch records prior to release.
Finished Product Release
The agreement should specify product release procedures and
identify the individuals who are responsible for approving release
for distribution.

Control of Changes, Process Deviations, and Product


Damage
The agreement should specify the individuals to be notified of
any changes or deviations in the manufacturing or sterilization
process. It should also specify the individual at the manufacturer
or manufacturing facility that should be contacted when product
is damaged to determine how the product should be handled at
the contract sterilizer.

Reprocessing of Loads

References

The agreement shall specify how reprocessing procedures are


established, implemented, and controlled to assure that the
reprocessing steps and product meet the validation and routine
processing specification criteria.

and routine control of ethylene oxide sterilization

Material Handling and Documentation


Adherence to Title 21, CFR, Part 801.150 is required for label
control. The agreement should specify how adherence is to be
controlled/conducted.
Contract Agreement Criteria
The written agreement shall specify all shipping arrangements
including labeling for shipping and should identify laboratories to
be used for sample testing.
The contract is a valuable tool to assure sterilization consistency
and regulatory compliance, and to help prevent
misunderstandings between the parties. It binds both parties to
the procedures and agreements which control all aspects of the
sterilization process.
