June 2003 Vol12 No2 Conclusion When the operator brushed hands strictly according to the regulations on sugical hand disinfection, there was no bacteria on the two hands and no poison and side-effect. 4 refs,2 tabs.

Effects of Multiple Cleaning and Disinfection Interventions on Infectious Diseases in Children: A Group Randomized Trial in China

Objective To assess the effectiveness of multiple cleaning and disinfection interventions in the homes and kindergartens, in reducing gastrointestinal and respiratory illnesses of children. Methods From October 2010 to September 2011, we performed a prospective, controlled study in China. 408 children under 5 years old were recruited and group randomized into intervention and control groups. Families and kindergartens in the intervention group were provided with antibacterial products for hand hygiene and surface cleaning or disinfection for one year. Each child＇s illness symptoms and sick leave were recorded every day. Results A total of 393 children completed the study, with similar baseline demographics in each of the 2 groups. Except for abdominal pain, the odds of symptoms （fever, cough and expectoration, runny nose and nasal congestion, diarrhea）, illness （acute respiratory illness and gastrointestinal illness）, and sick leave per person each month were significantly reduced by interventions. The rates of fever, diarrhea, acute respiratory illness, gastrointestinal illness and sick leave per person per year were significantly decreased as well. Conclusion Not only the acute respiratory children were significantly reduced by multiple and gastrointestinal illness but the sick leave rate in interventions.

Effectiveness of hospital disinfection and experience learnt from 11 years of surveillance

This survey was designed to assess the sanitation status of hospitals and the compliance of hospital staff to disinfection strategies within the past 11 years.A total of 199 provincial affiliated tertiary or secondary public hospitals from 2007 to 2017 were investigated and seven critical categories,namely indoor air,work surface,hand hygiene,ultraviolet(UV) irradiation intensity,use of disinfectants,sterilization of medical items,and effects of steam sterilizer,were monitored.The average qualified rates were(94.74±3.54)%(810/855),(97.25±1.65)%(1 876/1 929),(87.57±4.60)%(2 508/2 864),(95.00±4.50)%(1 196/1 259),and(98.76±1.14)%(1 599/1 619) for indoor air,work surface,hand hygiene,UV irradiation intensity,and sterilization of medical items,respectively.In terms of other categories,a few samples were not qualified:3/1 575 for use of disinfectants and 1/243 for effects of steam sterilizer.The hospital disinfection monitoring and supervision program effectively improved the effectiveness of disinfection.Routine monitoring and supervision must be conducted to ensure a safe hospital treatment environment.

Effects of some common additives on the antimicrobial activities of alcohol-based hand sanitizers

Objective: To study the effects of some common additives on the antimicrobial activities of alcohol-based hand sanitizers. Methods: The antibacterial activities of varying aqueous concentrations of ethanol and isopropyl alcohol were tested by the agar well diffusion method. The influences of different concentrations of glycerin was similarly tested. Finally, isopropyl alcohol and benzalkonium chloride were combined in different ratios within the sate use concentrations of each, and the effects of these combinations were compared with values obtained for the two agents used alone. Statistical methods, such as student t test and one-way ANOVA were used when appropriate to evaluate the differences in activity. Results: The activities of the alcohols showed marked concentration dependence, and both showed peak activity at 85%-95% concentration range. Over the concentration range of 60%-100%, isopropyl alcohol inhibited more bacterial and fungal organisms than ethanol, though the inhibition zone diameters it produced were not statistically different from those of ethanol for organisms which were sensitive to both of them.Addition of glycerin reduced the antimicrobial activities of the isopropyl alcohol, as shown by reduction in the inhibition zone diameters produced in vitro, which may be due to reduced drug diffusion with increase in viscosity. Addition of benzalkonium to isopropyl alcohol systems improved the activity of the alcohol, but the overall activity of the combination was not superior to that seen in the use of benzalkonium alone. Conclusion: Alcohol-based hand sanitizers should not be used outside the concentration range of 85%-95% and isopropyl alcohol inhibits more bacterial and fungal organisms than ethanol for most concentrations. Inclusion of benzalkonium improves the antimicrobial spectrum and activity of isopropyl alcohol, and the combination may justifiably be used to achieve both immediate and long lasting effect. Glycerin may adversely affect the antimicrobial activities of isopropyl alcohol-based hand sanitizers and should be used with caution.

Effectiveness of Disinfection in Bacteriology Laboratories in Togo, 2021

Background: Laboratory personnel is at risk of biological contamination leading to laboratory-acquired infections (LAIs). The use of disinfection products is essential in the prevention of these infections. This work aimed to evaluate the effectiveness of antimicrobial agents used in disinfection in bacteriology laboratories in Togo. Methods: This was a cross-sectional study conducted from June to December 2021 in all bacteriology laboratories in Togo. Swabs taken before and after disinfection of surfaces and staff hands were immediately plated on agar media. Counting and identification of isolated colonies were done after 24 hours of incubation. The ANOVA test was used to compare calculated means, prevalence ratio (PR) and 95% confidence intervals (CI) to compare bacterial frequencies. Results: A total of 393 samples were taken, of which 41.2% were from hands. Before disinfection, surfaces were more contaminated than hands with respectively 40.4% and 29.6% (PR = 1.3;CI 95% = [0.9 - 1.9]). After surface disinfection with 0.5% of chlorine solution, bacterial elimination was total, but partial on hands washed with soap, with residual contamination of 3.7%. A total of 108 strains were isolated before disinfection of which Klebsiella spp. 38.9% and Staphylococcus spp. 25.0%;after disinfection 4 strains were isolated of which: Staphylococcus spp. 75.0% and Klebsiella spp. 25.0%. Conclusion: Surface disinfection was more effective than hand washing with soap and water. We recommend proper hand washing.

手消毒剂对肠道病毒灭活效果研究进展

《医务人员手卫生规范WS/T313—2019》修订版出台后更规范了医务人员手消毒的要求。手消毒剂是提高手卫生效果,降低手传播病原微生物的有效工具,国家强制性标准《手消毒剂卫生要求GB27950—2010》规定了手消毒剂的卫生要求,但对灭活病毒指标却没有提出具体要求。目前,市场上常用的手消毒剂以醇类或以乙醇为溶剂的产品为主,而醇类消毒剂对于消毒抗力较强的肠道病毒灭活效果有争议。本文就手消毒剂对肠道病毒灭活效果的国内外研究进行综述,为医务人员合理选择手消毒剂提供参考。
