Filter by:The misuse, irrational, or overuse of antibiotics, antibiotic/antimicrobial resistance (AMR) is a global threat to human health. Even though the awareness of the potential threat from AMR is widespread, studies and monitoring programs describing the present situation are lacking. The presence of a 'pluralistic' health system and a large informal sector involving unqualified drug dispenser/providers/practitioners in Bangladesh is a matter of grave concern for the rising antimicrobial resistance situation in the country. An estimated 63% of antibiotic prescriptions are from unqualified providers. Besides, misconception about antibiotics is very common in Bangladesh. Meanwhile, the use of antibiotics in animal food production with insufficient veterinary supervision for therapeutic purposes which poses the risk of antimicrobial resistance transmission in the food chain. Without adherence to national regulations, unnecessary and inappropriate prescriptions become common practice, particularly in rural areas. Domestic drug industries contribute to easily accessible and affordable drugs. To tackle this problem, prescriptions and sales of antibiotics need to be regulated and integrated in a national HMIS. Awareness programs for antibiotic providers that promote understanding of antibiotics and antibiotic resistance through tailored interventions may be helpful in changing current antibiotic sales practices. Therefore, this study will attempt to identify the underlying causes of irrational anti-microbial usage in Bangladesh, which were grouped into four interlinked areas - lack of awareness among patients/ consumers (demand side), perverse incentives and lack of knowledge among providers (supply side), poorly regulated pharmaceutical marketing and retail sales (regulatory side) and lack of data and research evidence to support awareness raising and policymaking (enabler). A before-after designed quasi experimental study will be conducted in urban areas. Data will be collected in both qualitative and quantitative methods. Multi-cluster sampling method will be used to select study locations. Pharmacists or drug sellers and patients aged more than 18 years and located within selected intervention areas will be our target population. A baseline survey will be conducted among the pharmacy volunteers to evaluate their knowledge, perception, and practice of rational use of anti-microbials prior to any intervention. Additionally, a household survey will be conducted among community members applying systematic random sampling where one adult from every selected household will be approached maintaining gender equality. After collecting the baseline data, intervention will be given to the community people through awareness building campaign and distributing leaflets and posters on rational use of anti-microbials. After three months, a follow-up survey will be conducted among the same participants with the same questionnaire. For quantitative portion of the study, all the medicine shops in the selected study areas will be included in the study sample alongside a total of anticipated 6240 community dwellers. For qualitative part, the sample will be selected purposively until data saturation and a total of 20 experts will be interviewed. Two sets of questionnaires for pharmacy volunteers and the community dwellers will be prepared based on literature review that will include health literacy questions regarding anti-microbial use. The questionnaire for the follow-up data collection will include some additional questions regarding acceptability, adoption, feasibility, and cost of the intervention. The study is expected to bring light upon a comprehensive understanding of the current level of knowledge, perception and practice of irrational use of anti-microbials among target population. Furthermore, a digital intervention design will be produced to reduce irrational use of anti-microbials after considering its effectiveness. The wide range of the study findings will aid in assessing the acceptability, adoption, feasibility and cost of the intervention to make recommendations on sustainability and scaling up of the intervention programs.
Objectives: To test the hypothesis that certain levels of air pollution may lead to increases in 1) antimicrobial consumption in the general population and 2) the presence of antibiotic resistance genes. Methods: The project will consist of two sub-studies: 1. A time series analysis of the association between daily antimicrobial consumption and air pollution in the 11 largest cities in Catalonia (2006-2022). Outcome variable: daily consumption of antimicrobials. Independent variables: air pollution and confounding variables. The analysis will use generalized additive models: through a random effects meta-analysis, the concentration-response estimates for each city will be added together to calculate the overall estimates. 2. Descriptive observational study of the relationship between the concentration of resistance genes and antimicrobial consumption in the Barcelona area (2021-2023). Outcome variable: concentration of antibiotic resistance genes. Independent variables: defined daily dose of antimicrobials per 1000 inhabitants-day. Descriptive analysis of the concentration and diversity of antibiotic resistance genes according to air quality monitoring station (urban vs. hospital environment), month, and correlation with antimicrobial consumption.
Antimicrobial resistance is regarded as one of the major global public health threats, causing at least 700,000 deaths per year. It has been estimated that if the current problem of antimicrobial resistance is not effectively tackled, it would cause the death of 10 million people worldwide by 2050. Multi-drug resistant pathogen is the single most important contributing factor for inappropriate antibiotics therapy, and this in turn lead to higher mortality in patients with sepsis. The slow pace of development of new classes of antimicrobial agents limits the availability of effective therapy for multi-drug resistant organisms, both currently and in the near future. It is therefore of utmost importance to look for strategies to reduce the spread and burden of antimicrobial resistance. Intestinal microbiota probably played a dominant role in determining the risk of acquisition of multi-drug resistant organisms. For instance, findings from a mouse model showed that Barnesiella species conferred resistance to intestinal colonization by vancomycinresistant Enterococcus. Such findings were subsequently confirmed in human subjects. This is a prospective longitudinal observational study evaluating the correlation between changes in intestinal microbiota and acquisition of antimicrobial resistance in patients hospitalized for stroke. Adult patients admitted to the Medical unit of the Prince of Wales Hospital with a diagnosis of acute stroke will be screened for eligibility and will be invited to participate in this study. Data collected from this study will determine the correlation between antibiotics use and changes in intestinal microbiota in a cohort of hospitalized patients as well as the correlation between intestinal microbiota and acquisition of intestinal colonization or infection caused by resistant pathogens.
