Introduction Antimicrobial resistance (AMR) is a major global health threat, particularity in lower-middle-income countries (LMICs) where antibiotics are readily available, leading to antibiotic misuse. Educational interventions are lacking in Zambia. Our study assessed antimicrobial use and resistance knowledge, attitude and perceived quality of education relating to AMR in Zambian medical schools. Methods A cross-sectional anonymous survey of students at six accredited medical schools in Zambia using a self-administered questionnaire was administered, using Qualtrics. Chi-squared, Fisher exact test, Pearson correlation test and Student’s t-tests were performed for descriptive analyses. Multivariable logistic regression was used to examine associations between knowledge and antibiotic use, beliefs and behaviours. Analysis was performed in SAS version 9.4. Results One hundred and eighty responses from six medical schools were included in the final analysis. Fifty-six percent of students rated their overall education on antibiotic use as useful or very useful. Ninety-one percent thought that antibiotics are overused, and 88% thought resistance was a problem in Zambia. Only 47% felt adequately trained on antibiotic prescribing, and 43% felt confident in choosing the correct antibiotic for specific infections. Only 2% felt prepared interpreting antibiograms, 3% were trained to de-escalate to narrow-spectrum antibiotics, 6% knew how to transition from IV antibiotics to oral antibiotics, 12% knew of dosing and duration, and 14% understood the spectrum of activity of antibiotics. Forty-seven percent of respondents think hand hygiene is unimportant. Conclusions Medical students in Zambia expressed a good level of knowledge, but low levels of training and confidence regarding antimicrobial prescribing practices and resistance. Our study highlights training gaps and possible areas of intervention in the medical school curriculum.
Remote sensing (RS), satellite imaging (SI), and geospatial analysis have established themselves as extremely useful and very diverse domains for research associated with space, spatio-temporal components, and geography. We evaluated in this review the existing evidence on the application of those geospatial techniques, tools, and methods in the coronavirus pandemic. We reviewed and retrieved nine research studies that directly used geospatial techniques, remote sensing, or satellite imaging as part of their research analysis. Articles included studies from Europe, Somalia, the USA, Indonesia, Iran, Ecuador, China, and India. Two papers used only satellite imaging data, three papers used remote sensing, three papers used a combination of both satellite imaging and remote sensing. One paper mentioned the use of spatiotemporal data. Many studies used reports from healthcare facilities and geospatial agencies to collect the type of data. The aim of this review was to show the use of remote sensing, satellite imaging, and geospatial data in defining features and relationships that are related to the spread and mortality rate of COVID-19 around the world. This review should ensure that these innovations and technologies are instantly available to assist decision-making and robust scientific research that will improve the population health diseases outcomes around the globe.
Background Antimicrobial resistance (AMR) is widely acknowledged as a global health problem, yet its extent is not well evaluated, especially in low-middle income countries. It is challenging to promote policies without focusing on healthcare systems at a local level, therefore a baseline assessment of the AMR occurrence is a priority. This study aimed to look at published papers relating to the availability of AMR data in Zambia as a means of establishing an overview of the situation, to help inform future decisions. Methods PubMed, Cochrane Libraries, Medical Journal of Zambia and African Journals Online databases were searched from inception to April 2021 for articles published in English in accordance with the PRISMA guidelines. Retrieval and screening of article was done using a structured search protocol with strict inclusion/exclusion criteria. Results A total of 716 articles were retrieved, of which 25 articles met inclusion criteria for final analysis. AMR data was not available for six of the ten provinces of Zambia. Twenty-one different isolates from the human health, animal health and environmental health sectors were tested against 36 antimicrobial agents, across 13 classes of antibiotics. All the studies showed a degree of resistance to more than one class of antimicrobials. Majority of the studies focused on antibiotics, with only three studies (12%) highlighting antiretroviral resistance. Antitubercular drugs were addressed in only five studies (20%). No studies focused on antifungals. The most common organisms tested, across all three sectors, were Staphylococcus aureus, with a diverse range of resistance patterns found; followed by Escherichia coli with a high resistance rate found to cephalosporins (24–100%) and fluoroquinolones (20–100%). Conclusions This review highlights three important findings. Firstly, AMR is understudied in Zambia. Secondly, the level of resistance to commonly prescribed antibiotics is significant across the human, animal, and environmental sectors. Thirdly, this review suggests that improved standardization of antimicrobial susceptibility testing in Zambia could help to better delineate AMR patterns, allow comparisons across different locations and tracking of AMR evolution over time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
