Abstract

BACKGROUND

Adequate compliance with the existing guidelines for cleaning and disinfection of gastrointestinal endoscopes and accessories is necessary to obtain high-level disinfection and prevent pathogen transmission.

AIM

To investigate cleaning and disinfection practice in China.

METHODS

A questionnaire with 21 questions concerning gastrointestinal endoscopy reprocessing was sent by e-mail to 189 endoscopy units in China.

RESULTS

One hundred and twenty-two (80.39%) of the 189 units responded. Compared with the low-workload units (<5000 procedures/year), the high-workload units (≥5000 procedures/year) had a significantly higher number of gastrointestinal endoscopes (25.8 ± 3.6 vs. 4.7 ± 1.8, p < 0.01) and the higher possessing rate of automated endoscope reprocessors (43.9% vs. 3.1%, p<0.01). Glutaraldehyde was the most commonly employed disinfectant (88.5%) in all the units. In 23/122 (18.8%) units, the exposure time to glutaraldehyde was <45 min in the case of infectious disease patients. Eighty-six of 122 (70.5%) units reused disposable materials, of which 21/86 (24.4%) reused disposable forceps and disposable polypectomy hooks, and 2/86 (1.6%) reused disposable injection needles intermittently.

CONCLUSION

Although gastrointestinal endoscopy has developed rapidly in China in the past decade, there is still room for improvement in the practice of endoscopy reprocessing, especially in middle-sized and small cities.

摘要

背景

为了达到高水平消毒并防止病原体传播，充分遵守现有的胃肠内镜清洗消毒指南是必要的。

目的

调查中国的清洗消毒实践。

方法

通过电子邮件向中国 189 个内镜单位发送了一份包含 21 个问题的问卷，涉及胃肠内镜再处理。

结果

在 189 个单位中，有 122 个（80.39%）做出了回应。与低工作量单位（<5000 例/年）相比，高工作量单位（≥5000 例/年）拥有更多的胃肠内镜（25.8 ± 3.6 比 4.7 ± 1.8，p < 0.01）和更高的自动内镜清洗消毒器拥有率（43.9%比 3.1%，p<0.01）。戊二醛是所有单位最常用的消毒剂（88.5%）。在 23/122（18.8%）个单位中，传染病患者的戊二醛暴露时间<45 分钟。122 个单位中有 86 个（70.5%）重复使用一次性材料，其中 21/86（24.4%）重复使用一次性活检钳和一次性息肉切除术钩，2/86（1.6%）间歇性重复使用一次性注射针。
