Sterilization validation as an element of the regulatory sustainability of the project

Validation of the sterilization of medical devices is a documented confirmation that the selected sterilization process consistently and reproducibly ensures the level of sterility of products. It is a mandatory element of the quality system and the evidence base for product registration.
In the Russian regulatory system, sterility cannot be confirmed only by final tests of finished products. It is impossible to check each unit of the product, and random tests do not provide an absolute guarantee of safety. That is why legislation and applicable standards require confirmation not of the result of a single cycle, but of the ability of the process as a whole to ensure sterility during mass production. It is validation that solves this problem.
For sterile medical products, the availability of validation is a prerequisite for state registration. Information about the sterilization method used and confirmation of its validation are included in the registration dossier and evaluated by the regulator along with technical documentation and test results. The lack of a validated process means that the product cannot be considered safe to handle, even if laboratory tests have been formally carried out.
It should be noted that all applied sterilization methods, including steam, gas, radiation, dry-fire and other low-temperature technologies, are subject to validation. Regardless of the chosen method, the manufacturer must prove that the established sterilization regime ensures the achievement of a standard level of sterility and at the same time does not impair the properties of the product and its safety.
The validation procedure includes confirming the correct installation and functioning of the equipment, checking the reproducibility of the process parameters and evaluating its effectiveness on real products. Special attention is paid to the control of microbial contamination, the use of biological and chemical indicators, as well as the analysis of possible residual factors affecting patient safety. The validation results are issued in the form of protocols and a final report, which become part of the manufacturer's technical documentation.
It is important to distinguish between validation and routine sterility control. Validation confirms the ability of the process to ensure sterility in principle, while the current control is used to monitor each production cycle. These mechanisms complement each other, but are not interchangeable. The presence of routine control does not compensate for the lack of validation, and the lack of control makes the validated process unmanageable. Sterilization validation is not a one-time procedure. It is subject to revision and re-confirmation when the product, packaging, equipment, process parameters or production conditions change. Maintaining a validated condition is part of the manufacturer's responsibility throughout the medical device's handling.
