The highest unqualified cleaning rate of suction-type lumen instruments is a major challenge for a central sterile supply department (CSSD). However, A few comprehensive studies have analyzed the main factors affecting cleaning quality. In response, this study aimed to explore the current state and the factors affecting the cleaning quality of reused suction-type metal lumen instruments in CSSD. The results revealed that the qualified cleaning rates determined by the 5x magnifier visual inspection with light source method, OB reagent method, and ATP bioluminescence detection method were 94.2%, 72.6%, and 60.5%, respectively. The results also showed a significant difference between the three methods (X = 60.293, P < 0.001). Meanwhile, the binary logistic regression analysis revealed that the time interval between instrument recycling and cleaning, pollution level, pretreatment soaking time, cleaning technique, and the presence of visible bloodstains or dirt after pretreatment are independent risk factors that influence the cleaning quality of suction-type metal lumen instruments. Based on these results, the cleaning quality of suction-type metal lumen instruments needs further improvement.
吸引式腔镜器械的最高不合格清洗率是中央无菌供应室（CSSD）面临的一项重大挑战。然而，一些综合性研究分析了影响清洗质量的主要因素。对此，本研究旨在探讨CSSD中重复使用的吸引式金属腔镜器械的清洗质量现状及其影响因素。结果显示，采用带光源5倍放大镜目视检查法、OB试剂法和ATP生物发光检测法测定的合格清洗率分别为94.2%、72.6%和60.5%。结果还表明，这三种方法之间存在显著差异（X = 60.293，P < 0.001）。同时，二元逻辑回归分析显示，器械回收与清洗的时间间隔、污染程度、预处理浸泡时间、清洗技术以及预处理后可见血迹或污垢的存在是影响吸引式金属腔镜器械清洗质量的独立危险因素。基于这些结果，吸引式金属腔镜器械的清洗质量有待进一步提高。
