Product adoption and process equivalence for ethylene oxide sterilization1 ScopeThis document specifies the requirements for adoption of new or changed products to a validated sterilization process for medical devices using ethylene oxide sterilization. It provides methods for evaluating the equivalence of sterilization processes when using different sterilization equipment. This document applies to medical devices sterilized with ethylene oxide using conventional release or parametric release. This document applies to ethylene oxide sterilization of medical devices including. a) adding new products to a confirmed ethylene oxide sterilization process; b) evaluating changes to confirmed products; c) transferring a confirmed process to a different site or equipment; d) evaluating the equivalence of sterilization processes.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB 18279.1, Sterilization of health care products -- Ethylene oxide -- Part 1. Requirements for development, validation and routine control of a sterilization process for medical devices3 Terms and definitionsFor the purposes of this document, the terms and definitions defined in GB 18279.1 as well as the followings apply. 3.1 candidate equipment New or modified equipment intended to perform an existing validated sterilization process. 3.4 EO product family A combination of products that are sterilized using the same process conditions and have similar or identical validation purposes are permitted. 3.5 load configuration The total properties of the product as it will behave during the sterilization process. This structure includes. 3.6 packaging system Combination of sterile barrier system and protective packaging. 3.7 process equivalence A written evaluation that the same sterilization process can be run within specified parameters on two or more sterilization process equipment. 3.8 product adoption The process of introducing a candidate product into an existing, identified EO processing category or family of ethylene oxide products. 3.9 requalification Partial validation activities performed to confirm the continuing conformity of a specified process. 3.10 sterilization process equipment Including preprocessing area (if used), sterilization cabinet or sterilization cabinet, aeration area (if used) and their respective auxiliary equipment.4 Product adoption4.1 General Product adoption is generally intended to simplify the performance qualification procedures required to introduce products into EO product family or EO processing category. The product adoption approach described in this document includes the establishment of EO product family and EO processing category and recommended practices for maintaining these product families and processing categories. 4.2 Product families and processing categories A product family is a group of products identified as having similar or identical confirmed purposes. 4.3 Determination of adverse product effects Before determining whether a candidate product or a candidate packaging system can be added to a product family or processing category, it shall be determined whether the candidate product or candidate packaging system still retains functionality and effectiveness. The design or change control process shall provide a system for evaluating these aspects. 4.4 Determination of impact on product design The design of the candidate product shall be carefully reviewed for changes that create a greater barrier to ethylene oxide gas, heat, or moisture penetration than the existing product or process challenge device. Examples of product changes are longer lumens, additional closures, or more bonding surfaces. 4.6 Determination of impact on sterile barrier system The candidate product's sterile barrier system shall be examined for factors that create barriers to the penetration of ethylene oxide, heat, or moisture. These factors could be reduced porosity of the permeable material, reduced permeable surface area, closed permeable surfaces, or any other feature that makes the candidate product more challenging to sterilize than existing products or process challenge devices. In addition, the potential impact of changes in the sterile barrier system on the product's bioburden and ethylene oxide residuals shall be evaluated. 4.7 Determination of the impact on load configuration The loading pattern of the candidate product shall be carefully examined for any changes that could affect the thermodynamic response of the sterilization process. These changes could include the addition of more layers of wrap, reconfiguration of the tray, changes in load dimensions, changes in overall load density, or any other changes that would make the candidate product more challenging to sterilize. 4.9 Documents The decision on the analytical results that determine whether the candidate product can be added to the confirmed EO product family or EO processing category shall be documented. This document shall include at least the following.5 Process equivalence5.1 General Process equivalence is a method used to demonstrate that two or more pieces of equipment are capable of performing the same validated sterilization process. This does not require that the equipment be identical. Even if the parameters under which the equipment is run are statistically different, if the equipment has the ability to run the sterilization process within the specified validated range, the process is considered equivalent in that equipment. 5.2 Requirements for process equivalence Process equivalence can be established regardless of whether the equipment is located in the same location or in different locations. Before establishing a process equivalence program, the following requirements shall be met. 5.3 Determination of process equivalence Sterilization process equivalence between equipment is established by comparing data obtained from running the same validated process on each equipment separately. This comparison shall include an evaluation of the ability of the equipment to reproducibly achieve the expected process parameters when sterilizing routine production loads. 5.4 Process analysis and evaluation Perform data analysis related to the confirmed process for the candidate equipment and the initial equipment. Process data shall be collected from the candidate equipment. These data shall be compared with the parameter range of the specific sterilization process and the data obtained during the performance qualification process of the initial equipment. 5.5 Preprocessing or parsing area evaluation The requirements for preprocessing or establishing process equivalence in analytical area are the same. Usually there is no humidity requirement for the analytical area. An evaluation shall be performed to compare the temperature and humidity profiles of the load in each environment. At a minimum, the consistency of temperature and humidity within the load shall be evaluated and the relationship of this consistency to the corresponding set points and control ranges recorded for that area. If the equipment uses different set points or has different control ranges, it may not be possible to claim equivalence. 5.7 Microbiological evaluation Run a partial cycle or half cycle during the microbiological evaluation to demonstrate that the sterilization process is capable of achieving the specified minimum sterility assurance level in all evaluated equipment. 5.8 Results evaluation The results of the evaluation will determine whether the different equipment (sets) operate equivalently. If the different equipment (sets) is equivalent, the tests that have been implemented have met the requirements for performing simplified microbial performance identification. 5.9 Equivalence maintenance Equivalency maintenance shall include a review of changes to each piece of equipment, manufacturing process, product loading, and sterilization process to ensure that these changes do not affect the overall equivalence determination. This review shall be performed prior to the change and as part of the change control process. If any process fails the periodic equivalence review, it shall be removed from the equivalency equipment catalog and requalified on its own. 5.10 Documents All analytical results relevant to determining whether the candidate equipment can claim equivalence to existing sterilization process equipment shall be documented. This documentation shall include at least the following. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
