Objective To explore the grasping and implementing state of nurses in digestive endoscopy in 2016 "regulation for cleaning and disinfection technique of flexible endoscope",so as to provide a reference for formulating and perfecting professional training plan in cleaning and disinfection for flexible endoscope.Methods We investigated 100 nurses participating in Jilin digestive endoscopy nursing academic exchange in July 2017 with the self-designed questionnaire and engaging in cleaning as well as disinfection work for digestive endoscopy.Results A total of 104 valid questionnaire were collected with 94.54％ for the effective recovery.The mean of regulation related knowledge of 104 nurses in digestive endoscopy was (22.93 ± 4.416) and the total scoring rate was 71.66％.The score of knowledge on cleaning and disinfection for flexible endoscope of nurses who attend digestive endoscopy training had a statistical significance compared with that of nurses who did not attend the training (P ＜ 0.05).Among the mandatory terms of "regulation for cleaning and disinfection technique of flexible endoscope",the qualified implementation rate (24.04％) in "facilities and equipment should be allocated in cleaning and disinfection room" of was the lowest.Among the recommendable terms,the implementation rate (13.31％) in "exhaust modes should be adopted in endoscopy cleaning and disinfection room" was the lowest.There were statistical differences in qualified implementation rates among hospitals with different levels (P ＜ 0.05).Conclusions The knowledge of nurses in digestive endoscopy of Jilin Province on "regulation for cleaning and disinfection technique of flexible endoscope" is in a middle level and the implementation is not optimistic.We should strengthen to unscramble,generalize knowledge and skill training as well as improving clinical effective implementation rates.

Objective? To explore the application effect of FOCUS-PDCA mode(l find, organize, clarify, understand, select, plan, do, check, act) in improving the pre-cleaning process of flexible endoscopes. Methods? Totally 19 920 cases of digestive endoscopes used for diagnosis and treatment before the implementation of FOCUS-PDCA model from March to May 2018 were taken as the control group and 12 700 cases of digestive endoscopes used after the implementation of FOCUS-PDCA model from June to July 2018 were taken as the observation group. The pre-cleaning process was carried out according to "WS 507-2016 Technical Specification for Endoscopic Cleaning and Disinfection" in the control group. The FOCUS-PDCA model was carried out in the observation group to analyze the factors affecting the quality of flexible endoscopy pre-cleaning, establish a continuous quality improvement group to improve and standardize the process, analyze and compare the two groups in terms of the flexible endoscope water and gas pipeline blockage rate and endoscopy nurses' related knowledge; sampling and compare the pre-cleaning performance and manual cleaning quality between the two groups. Results? The qualified rates of flexible endoscopes pre-cleaning and manual cleaning were 95.56% and 94.50% respectively,which were significantly higher than the control group (81.50% and 86.50%) with statistical difference (χ2=135.285,7.444;P＜ 0.05). The blockage rate of water and gas pipelines in the control group was 0.26%, higher than the observation group(0.03%) with statistically significant difference (χ2=23.228,P＜ 0.001). The score of endoscopy nurses' knowledge increased from (75.0±6.071) to (87.6±4.823),and the difference was statistically significant (t=12.734, P＜ 0.001). Conclusions? The application of FOCUS-PDCA model to manage, improve and standardize the pre-cleaning operation process effectively improves the qualified rate of pre-cleaning execution and manual cleaning, reduces the blockage rate of water and gas pipelines in flexible endoscopes,and ensures the quality of endoscopy reprocessing.

Objective:To explore the quality management status of the final rinse water for flexible endoscope in medical institutions in Jilin Province, and analyze the factors affecting the quality of purified water.Methods:From January to May 2020, 75 medical institutions in Jilin Province were selected as subjects by convenience sampling. A self-designed Flexible Endoscopic Final Rinse Water Quality Management Questionnaire was used to investigate the managers of the Endoscopy Center in 75 medical institutions. The final rinse water of medical institutions was sampled on site, and 159 water samples were collected from the water treatment equipment terminal, water storage tank outlet and use terminal outlet, and the total number of bacteria was detected by pouring and filtration method. A total of 75 questionnaires were distributed, and 72 valid questionnaires were recovered, with a valid recovery rate of 96.00%.Results:A total of 40.28% (29/72) of medical institutions passed the final rinse water biological test results, and there was no statistically significant difference in the rate of passing the final rinse water biological test between different levels of medical institutions ( P>0.05) . In terms of the final rinse water production equipment configuration of medical institutions, the type of final rinse water, the availability of water treatment equipment, water treatment process, the installation of raw water pretreatment device, and the installation of disinfection device were the influencing factors of the biological test results of final rinse water, and the difference was statistically significant ( P<0.05) . In terms of the maintenance of the final rinse water production equipment, whether to record the maintenance of the final rinse water, whether to replace the filter membrane regularly, whether to disinfect the water storage tank and the disinfection of the pipeline in the medical institutions that installed the raw water pretreatment and filter membrane and other equipment were the influencing factors of the biological test results of the final rinse water, and the difference was statistically significant ( P<0.05) . In terms of the final rinse water quality monitoring, the establishment of the final rinse water quality monitoring system and the monitoring record were the influencing factors of the final rinse water biological detection results with a statistical difference ( P<0.05) . Conclusions:Medical institutions should pay attention to the quality control of the final rinse water for endoscope by relevant departments, increase financial support and scientific research support, formulate and improve relevant specifications, and unify industry standards and behaviors, so as to ensure the quality of the final rinse water for flexible endoscope and medical safety.
