ObjectiveTo study the effect of PDCA cycle model on the standardization of the application of common disinfectants, in order to promote the management level of hospital disinfection. MethodsBy questionnaire and observation, the study was to learn the knowledge and its application in medical workers on common disinfectants. Based on the results, we tried to regulate effective preventive measures and carry out continuous improvements. ResultAfter the implementation of PDCA cycle model, the awareness rate of the medical staff on disinfection and the application accuracy of disinfectants were significantly increased (P<0.05). ConclusionThe implementation of PDCA cycle model can improve nosocomial infection management level effectively, ensure medical quality management and patients' safety, which is an effective way of management to reduce the rate of nosocomial infection.
目的 分析多功能空氣消毒機在普通內科病房的動態消毒效果，為病房空氣質量的控制提供參考依據。 方法 2010年9月－2011年4月對普通內科病房在動態狀態下進行細菌檢測并使用多功能空氣消毒機消毒，并就消毒前后的空氣細菌菌落總數進行分析比較。 結果 在動態狀態下，病房關門關窗并開啟空調機時，使用多功能空氣消毒機消毒前的空氣細菌菌落總數顯著高于消毒后，差異有統計學意義（P＜0.05）；病房在開門開窗時，使用多功能空氣消毒機消毒前后的空氣細菌菌落總數比較，差異無統計學意義（P＞0.05）。 結論 普通內科病房在關門關窗并開啟空調機動態狀態下，使用多功能空氣消毒機可以降低空氣細菌菌落總數，改善房間空氣質量。
ObjectiveTo investigate on preoperative hand-washing for analyzing the underlying problems, in purpose of preventing operation-related infection via strengthening the standardization of surgical hand-washing and hand-disinfection. MethodsFrom July to September 2014, surveillance video of pre-operative hand-washing was studied and analyzed. We randomly selected 100 subjects, and assessment was performed based on the self-made surgical hand-washing and hand-disinfection protocol. Grading was done strictly. The passing score was 60 or higher; a score of 70-79 meant good; and a score of 80-100 indicated excellence. ResultsIn the survey, 91 in the 100 subjects were qualified. Among the qualified subjects, there were 53% of excellence and 20% of good. The major problems included erroneous methods, step omissions, time lacking, pollution, wrong flushing method or dry-hand method, and insufficient washing time. ConclusionBased on the survey, the administration department is advised to strengthen the regulatory supervision and education training based on standard surgical hand-washing and hand-disinfection criteria, especially training interns and new staff, in purpose of reducing the incidence of operation-related infection and improving hospitalization management qualities.
ObjectiveTo investigate the disinfection effect of dry-fogging hydrogen peroxide (DFHP) on ambulance inner surfaces.MethodsThis study was carried out using simulated field test and field test from October to December 2018. In the simulated field test, the carriers with Geobacillus stearothemopilus (ATCC12980) spores were placed in 6 places in the ambulance, and disinfected for 60 minutes with DFHP of 0.38–0.72 g/m3. The carriers were cultured for up to 7 days to observe whether the bacteria were eliminated. Before and after the DFHP disinfection, the microbial sampling of the surface in the ambulance was carried out, and the colonies were counted after the cultivation.ResultsThe eliminating rate of the bacteria carriers on the uncovered surface was 100% (20/20), and that of the covered surface was 10% (1/10). The pass rate of microbial sampling was 100% (26/26).ConclusionsThe DFHP had a significant decontamination effect on the ambulance inner uncovered surfaces. The DFHP equipment is automated and their disinfecting quality is consistent, therefore it is suitable for the disinfection of ambulance inner surfaces. But the limitation of disinfection effect on covered surfaces should be avoided.
ObjectiveTo systematically review the safety of hand disinfectants. MethodsPubMed, EMbase, The Cochrane Library, INAHTA, WanFang Data, CNKI and VIP databases were electronically searched to collect studies on the safety of hand disinfectants from inception to February 1st, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies; then, a systematic review was conducted. ResultsA total of 50 studies were included. The reported adverse events were eye and nasal mucosal irritation, hand adverse events with skin itching, rash, erythema, edema and so on. A total of 29 brands such as 3M Avagard and 26 ingredients such as ethanol were reported to be related to the above adverse events. Hand disinfectants containing glycerin, silicone oil, vitamin B, plant extracts and other emollients could reduce the incidence of adverse events. ConclusionCurrent evidence shows that hand disinfectants containing emollients and free from ethanol, chlorhexidine and other ingredients are related to fewer adverse events. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
Endoscopic retrograde cholangiopancreatography is one of the main methods for the diagnosis and treatment of biliary tract and pancreatic diseases. Compared with other digestive endoscopes, duodenoscopy has a special structure. Since the outbreaks of nosocomial infections caused by the transmission of multidrug-resistant organism through duodenoscopy in 2010, the reprocessing and design of digestive endoscopes represented by duodenoscopy have faced new challenges. This article reviews the international advances in duodenoscopy reprocessing in the past 10 years including the structural characteristics of duodenoscope, related infection outbreak cases, outbreak control measures, and the use of disposable duodenoscopy, so as to provide guidance and reference for the duodenoscopy reprocessing and related nosocomial infections prevention and control work in China.
