In recent years, the Emergency Care Research Institute has advised that endoscope cleaning is of considerable importance. In the present study, a quality control circle (QCC) was used to reduce the formation of biofilms in flexible endoscopes within one hospital in Guangdong Province, China.
During reprocessing of 235 flexible endoscopes in the urology surgical suite, adenosine triphosphate (ATP) detection was used to monitor the efficacy of biofilm removal. The internal and external parts of flexible endoscopes were used as sampling sites by means of the flushing and smudge methods, respectively. When the two results reached the standard of less than 500 relative light units/piece at the same time, endoscopic biofilm clearance was considered to be qualified. A QCC was established to implement a 10-step plan-do-check-act model.
The baseline qualified rate (i.e., ATP monitoring pass rate) during reprocessing of 235 flexible endoscopes was 50%. During the study, the qualified rate increased to 85.29% after establishment of the QCC. During reprocessing of 150 flexible endoscopes in the following 6 months, the qualified rate remained at 90%.
Establishment of the QCC improved the removal of biofilm from flexible endoscopes in the urology surgical suite.
近年来，急救护理研究所在内镜清洗方面提出了一些建议，认为内镜清洗非常重要。本研究采用品管圈（QCC）降低了中国广东省某医院泌尿科手术室内柔性内镜生物膜的形成。
对泌尿科手术室内的 235 个柔性内镜进行再处理，采用三磷酸腺苷（ATP）检测来监测生物膜清除效果。分别采用冲洗法和涂抹法对内镜的内外表面进行采样。当两种方法的结果均达到每个内镜 500 相对光单位以下的标准时，即认为内镜生物膜清除合格。建立品管圈实施 10 步计划-实施-检查-行动模型。
235 个柔性内镜再处理过程中的基线合格率（即 ATP 监测合格率）为 50%。建立品管圈后，合格率提高至 85.29%。在接下来的 6 个月里，对 150 个柔性内镜进行再处理，合格率仍保持在 90%。
品管圈的建立提高了泌尿科手术室内柔性内镜生物膜的清除效果。
