Abstract

Background/aims: This study aimed to assess the impact of INTERCEPT Foam Spray (IFS) application on delayed endoscope reprocessing through microbiological surveillance culture (MSC).

Methods: A quasi-experimental, matched-comparison pilot study was conducted using gastrointestinal endoscopy. IFS was applied to the endoscopes after precleaning and before reprocessing the next day. An equal number of endoscopes, matched by endoscope type, were subjected to routine reprocessing. The MSC were subjected to high-level disinfection to detect any contamination. Data were analyzed using the chi-square test or Fisher exact test (categorical data) and Student t-test (continuous data).

Results: In total, 150 MSCs were collected from 42 endoscopes. Positive MSCs were observed in 4.0% (4/75) of the sprayed group and 1.3% (1/75) of the control group (95% confidence interval [CI], 30.34-0.31; p>0.05), all of which were contributed by colonoscopes. Colonoscope were more prone to positive MSC (mean difference in percentage, p<0.05). Mean spraying hours were not associated with detected growth (11.7% vs. 13.6; 95% CI, 1.43 to -5.27; p>0.05), with environmental and skin flora being the primary contaminants.

Conclusions: IFS may be applied when delayed endoscope processing is necessary, but with caution when applied to colonoscopes. However, further research is warranted to verify the result.

INTERCEPT 泡沫喷雾后内窥镜的微生物监测结果:新加坡的一项准实验性试点研究。
背景/目的:本研究旨在通过微生物监测培养(MSC)评估 INTERCEPT 泡沫喷雾剂(IFS)的应用对延迟内窥镜再处理的影响:方法: 使用消化道内窥镜进行了一项准实验、匹配比较试验研究。在预清洗后和第二天再处理前,对内窥镜进行 IFS 处理。同样数量的内窥镜按内窥镜类型进行匹配,并进行常规再处理。对 MSC 进行高水平消毒,以检测是否存在污染。数据分析采用卡方检验或费雪精确检验(分类数据)和学生 t 检验(连续数据):结果:总共从 42 个内窥镜中收集到 150 个间叶干细胞。喷洒组中有 4.0%(4/75)的间充质干细胞呈阳性,对照组中有 1.3%(1/75)的间充质干细胞呈阳性(95% 置信区间 [CI],30.34-0.31;P>0.05),所有这些间充质干细胞均来自结肠镜。结肠镜更容易出现 MSC 阳性(百分比的平均差异,P0.05),环境和皮肤菌群是主要污染物:结论:当需要延迟处理内窥镜时,可以使用 IFS,但在使用结肠镜时要谨慎。结论:当需要延迟内窥镜处理时,可以采用 IFS,但在应用于结肠镜时要慎重。不过,还需要进一步研究来验证这一结果。
