Both methods must be used in combination with process data, in accordance with ISO 11135:2014. Process parameters can be classified as control, monitor, or both. Control parameters can be altered directly to change the readings of monitoring variables, which can't be directly controlled themselves. Currently, ISO 11135:2014 does not allow PR based on control parameters for EO concentration and humidity (calculated via pressure increment). Sterilant concentration and relative humidity (RH) can only be measured using gas analyzer probes (or similar), despite the challenges of data variance and range, calibration, redundancy, and increased sensitivity to deviations involved with use of such probes. The current article sought to experimentally determine the capacity of statistical process control to detect changes in the process, to act as an early-warning system for an out-of-specification result, and to demonstrate the use of more reliable process data for the purpose of PR. Process data from 100 routine cycles were used to trend the achieved levels of chamber RH, temperature, and EO concentration (measured by gas analyzer probes or similar), and process derived data were compared with data provided by gas analyzer probes. Process trending of routine runs was found to predict process failures, and calculating EO/water concentration via pressure increment was determined to be a viable alternative to measurement by gas analyzer probe. Further, reduced variability in key parameters enables a reduction in sterilant use.</p>","PeriodicalId":35656,"journal":{"name":"Biomedical Instrumentation and Technology","volume":"59 1","pages":"99-107"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12007836/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regulatory expectations from U.S. and European Union authorities differ, particularly regarding whether manufacturers must conduct EOL testing or if a cautionary statement in the instructions for use is sufficient. ISO 10993-1:2021 mandates biological safety evaluations for the maximum validated number of processing cycles. Similarly, ISO 17664-1:2021, regulation (EU) 2017/745, and Food and Drug Administration guidance require manufacturers to determine whether repeated processing causes degradation that could limit a device's usable life. However, these documents provide limited direction on how to perform such assessments, leaving a gap in standardized methodology. This study aimed to develop a practical and reproducible protocol for EOL evaluation, reflecting real-world clinical use and manufacturer-recommended processing instructions. The primary objective was to assess whether biological or chemical residues remained on devices after repeated use and processing. A theoretical estimate of 100 use and processing cycles was used, representing a reasonable service life based on routine clinical conditions. A simulated 100-cycle protocol, including soiling, cleaning, and sterilization testing, revealed negligible to nondetectable residual contaminants on both surrogate coupons and actual devices. These results suggest that even under worst-case conditions, devices can be processed effectively without substantial accumulation of contaminants, supporting the selected EOL threshold. This approach offers a reproducible framework for manufacturers to evaluate and validate EOL claims, addressing a critical regulatory and practical challenge.</p>","PeriodicalId":35656,"journal":{"name":"Biomedical Instrumentation and Technology","volume":"59 1","pages":"128-135"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12154862/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144267450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Valid and reliable sampling methods are critical for monitoring processing effectiveness in flexible endoscopes. In this study, the effectiveness of protein extraction via turbulent fluid flow (TFF) sampling was compared with flush-only sampling in manually cleaned gastrointestinal endoscopes. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; A crossover study design, in which both sampling methods were used in alternating order during each endoscope encounter, was utilized to assess protein levels after colonoscopes and gastroscopes underwent manual cleaning.

Protein levels were quantified using a spectrophotometer. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; Protein samples were collected during a total of 40 encounters with 20 unique endoscopes (19 colonoscopes and 21 gastroscopes) following procedural use. More effluent was captured following TFF (20-30 mL) compared with flush-only (19-21 mL) sampling. Zero samples had detectable protein after flush-only sampling, and nine samples (22.5%; two gastroscopes and seven colonoscopes) had detectable protein following TFF sampling (range 1-4 μg/mL).
