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.展开更多

Methods: This was a cross-sectional and evaluative study which took place from 03 February to 20 July 2016. The study was carried out in the mono departmental hospital of Lokossa. The non-probabilistic sampling method was used to select all our study materials and all our targets were systematically selected. Our study materials involved observation checklist, guidelines documents and questionnaires to collect data. The assessment of the quality of the hospital management of severe acute malnutrition was based on national and international standards like Benin’s national protocol of acute malnutrition management. Results: In our study, 27 cases of severe acute malnutrition (SAM) in children were considered. The median age of those children was 12 months. The rates of the components inputs, process and results were 25% (poor), 58.33% (acceptable) and 40% (poor), respectively. The sub components with respect to the norms were all related to the management of severe acute malnutrition like, availability of therapeutic foods ready for use, availability of management protocol, availability of trained and supervised staff in the management of the severe acute malnutrition and the proportion of dead and cured children. The study showed that the quality of the management of severe acute malnutrition at the mono departmental hospital of Lokossa was poor with a rate of 41.38%. Conclusion: The quality of the management of severe acute malnutrition at the mono departmental hospital of Lokossa was poor. The sub components that need to improve were the availability of therapeutic foods ready for use, availability of management protocol, along with the training and supervision of staff in charge of the management of severe acute malnutrition.展开更多
