RESUMO

INTRODUCTION: Antimicrobial resistance (AMR) is a global concern. Currently, the greatest mortality due to AMR is in Africa. A key driver continues to be high levels of dispensing of antibiotics without a prescription. AREAS COVERED: A need to document current rates of dispensing, their rationale and potential ways forward including antimicrobial stewardship programmes (ASPs). A narrative review was undertaken. The highest rates of antibiotic purchasing were in Eritrea (up to 89.2% of antibiotics dispensed), Ethiopia (up to 87.9%), Nigeria (up to 86.5%), Tanzania (up to 92.3%) and Zambia (up to 100% of pharmacies dispensing antibiotics without a prescription). However, considerable variation was seen with no dispensing in a minority of countries and situations. Key drivers of self-purchasing included high co-payment levels for physician consultations and antibiotic costs, travel costs, convenience of pharmacies, patient requests, limited knowledge of antibiotics and AMR and weak enforcement. ASPs have been introduced in some African countries along with quality targets to reduce inappropriate dispensing, centering on educating pharmacists and patients. EXPERT OPINION: ASP activities need accelerating among community pharmacies alongside quality targets, with greater monitoring of pharmacists' activities to reduce inappropriate dispensing. Such activities, alongside educating patients and healthcare professionals, should enhance appropriate dispensing of antibiotics and reduce AMR.

RESUMO

OBJECTIVES: The understanding of antimicrobial utilization patterns is pertinent to successful implementation of the National Action Plans on Antimicrobial Resistance (AMR). There is, however, limited information on antibiotics utilization in Nigeria. This study was undertaken to build on existing information and provide direction for appropriate interventions including Antibiotics Stewardship Programs (ASP). METHOD: A Point Prevalence Study (PPS) was conducted in two public urban health facilities in Lagos, Nigeria using a design adapted from the European Center for Disease Prevention and Control (ECDC) and Global-PPS surveys. RESULTS: The prevalence of antibiotics use was 80.6% administered mostly parenterally (83.1% of total prescriptions) with concerns with extended surgical antibiotics prophylaxis. The mostly used antibiotics in the secondary hospital were parenteral metronidazole (32.4%), ceftriaxone (27.5%), and amoxicillin + clavulanate (8.2%) while the mostly used in the tertiary hospital were ceftriaxone (25.3%), parenteral metronidazole (19.1%), and amoxicillin + clavulanate (9.3%). There was an appreciable lack of specific functional capacities, policies, and processes to promote appropriate antimicrobial use in both hospitals. CONCLUSIONS: There is high rate of antibiotics utilization in these facilities with lack of institutional frameworks and processes for ensuring appropriate antibiotic use. The study provides the information needed to improve future antimicrobial use in hospitals and reduce AMR.

RESUMO

BACKGROUND: There has been an appreciable increase in the number of people in Africa with metabolic syndrome and Type 2 diabetes (T2DM) in recent years as a result of a number of factors. Factors include lifestyle changes, urbanisation, and the growing consumption of processed foods coupled with increasing levels of obesity. Currently there are 19 million adults in Africa with diabetes, mainly T2DM (95%), estimated to grow to 47 million people by 2045 unless controlled. This has a considerable impact on morbidity, mortality and costs in the region. There are a number of issues to address to reduce the impact of T2DM including improving detection rates and current access to services alongside addressing issues of adherence to prescribed medicines. There are also high rates of co-morbidities with infectious diseases such as HIV and tuberculosis in patients in Africa with T2DM that require attention. OBJECTIVE: Document ongoing activities across Africa to improve the care of patients with T2DM especially around issues of identification, access, and adherence to changing lifestyles and prescribed medicines. In addition, discussing potential ways forward to improve the care of patients with T2DM based on ongoing activities and experiences including addressing key issues associated with co-morbidities with infectious diseases. OUR APPROACH: Contextualise the findings from a wide range of publications including internet based publications of national approaches coupled with input from senior level government, academic and other professionals from across Africa to provide future guidance. ONGOING ACTIVITIES: A number of African countries are actively instigating programmes to improve the care of patients with T2DM starting with improved diagnosis. This recognises the growing burden of non-communicable diseases across Africa, which has been neglected in the past. Planned activities include programmes to improve detection rates and address key issues with diet and lifestyle changes, alongside improving monitoring of care and activities to enhance adherence to prescribed medicines. In addition, addressing potential complexities involving diabetes patients with infectious disease co-morbidities. It is too early to fully assess the impact of such activities. CONCLUSION: There are a number of ongoing activities across Africa to improve the management of patients with diabetes including co-morbidities. However, more needs to be done considering the high and growing burden of T2DM in Africa. Ongoing research will help further benefit resource allocation and subsequent care.

RESUMO

BACKGROUND: Currently about 19 million people in Africa are known to be living with diabetes, mainly Type 2 diabetes (T2DM) (95%), estimated to grow to 47 million people by 2045. However, there are concerns with early diagnosis of patients with Type 1 diabetes (T1DM) as often patients present late with complications. There are also challenges with access and affordability of insulin, monitoring equipment and test strips with typically high patient co-payments, which can be catastrophic for families. These challenges negatively impact on the quality of care of patients with T1DM increasing morbidity and mortality. There are also issues of patient education and psychosocial support adversely affecting patients' quality of life. These challenges need to be debated and potential future activities discussed to improve the future care of patients with T1DM across Africa. METHODOLOGY: Documentation of the current situation across Africa for patients with T1DM including the epidemiology, economics, and available treatments within public healthcare systems as well as ongoing activities to improve their future care. Subsequently, provide guidance to all key stakeholder groups going forward utilizing input from senior-level government, academic and other professionals from across Africa. RESULTS: Whilst prevalence rates for T1DM are considerably lower than T2DM, there are concerns with late diagnosis as well as the routine provision of insulin and monitoring equipment across Africa. High patient co-payments exacerbate the situation. However, there are ongoing developments to address the multiple challenges including the instigation of universal health care and partnerships with non-governmental organizations, patient organizations, and pharmaceutical companies. Their impact though remains to be seen. In the meantime, a range of activities has been documented for all key stakeholder groups to improve future care. CONCLUSION: There are concerns with the management of patients with T1DM across Africa. A number of activities has been suggested to address this and will be monitored.

RESUMO

Introduction: Antibiotics are indispensable to maintaining human health; however, their overuse has resulted in resistant organisms, increasing morbidity, mortality and costs. Increasing antimicrobial resistance (AMR) is a major public health threat, resulting in multiple campaigns across countries to improve appropriate antimicrobial use. This includes addressing the overuse of antimicrobials for self-limiting infections, such as upper respiratory tract infections (URTIs), particularly in lower- and middle-income countries (LMICs) where there is the greatest inappropriate use and where antibiotic utilization has increased the most in recent years. Consequently, there is a need to document current practices and successful initiatives in LMICs to improve future antimicrobial use.Methodology: Documentation of current epidemiology and management of URTIs, particularly in LMICs, as well as campaigns to improve future antimicrobial use and their influence where known.Results: Much concern remains regarding the prescribing and dispensing of antibiotics for URTIs among LMICs. This includes considerable self-purchasing, up to 100% of pharmacies in some LMICs. However, multiple activities are now ongoing to improve future use. These incorporate educational initiatives among all key stakeholder groups, as well as legislation and other activities to reduce self-purchasing as part of National Action Plans (NAPs). Further activities are still needed however. These include increased physician and pharmacist education, starting in medical and pharmacy schools; greater monitoring of prescribing and dispensing practices, including the development of pertinent quality indicators; and targeted patient information and health education campaigns. It is recognized that such activities are more challenging in LMICs given more limited resources and a lack of healthcare professionals.Conclusion: Initiatives will grow across LMICs to reduce inappropriate prescribing and dispensing of antimicrobials for URTIs as part of NAPs and other activities, and these will be monitored.

RESUMO

A number of activities are ongoing to reduce AMR in Botswana by improving antimicrobial utilization across all sectors. However, there is a need to share experiences. With the objective of sharing these, the second one day symposium was held in the University of Botswana in October 2018 involving both private and public hospitals. In Lenmed Bokamoso hospital, ESKAPE organisms were associated with 50-90% of clinical infections; however, there was no correlation between healthcare associated infections (HAIs) and admission swab positivity with ESKAPE or ESBL isolates. Hang times, the time between a prescription and IV administration, were also discussed. At Nyangabwe Hospital, the prevalence of HAIs was 13.54%, 48.9% were laboratory confirmed of which 8.5% were blood stream infections (BSIs). The prevalence of different bacteria causing neonatal BSIs was also investigated. At Princess Marina Hospital, positive cultures were seen in 22.4% of blood cultures with contaminants comprising the majority. Several activities are ongoing in Botswana across sectors as a result of the findings and will be periodically reported to further improve antibiotic utilization.

RESUMO

Objective: There is an urgent need to undertake Point Prevalence Surveys (PPS) across Africa to document antimicrobial utilisation rates given high rates of infectious diseases and growing resistance rates. This is the case in Botswana along with high empiric use and extended prophylaxis to prevent surgical site infections (SSIs) Method: PPS was conducted among all hospital sectors in Botswana using forms based on Global and European PPS studies adapted for Botswana, including rates of HIV, TB, malaria, and malnutrition. Quantitative study to assess the capacity to promote appropriate antibiotic prescribing. Results: 711 patients were enrolled with high antimicrobial use (70.6%) reflecting an appreciable number transferred from other hospitals (42.9%), high HIV rates (40.04% among those with known HIV) and TB (25.4%), and high use of catheters. Most infections were community acquired (61.7%). Cefotaxime and metronidazole were the most prescribed in public hospitals with ceftriaxone the most prescribed antimicrobial in private hospitals. Concerns with missed antibiotic doses (1.96 per patient), high empiric use, extended use to prevent SSIs, high use of IV antibiotics, and variable infrastructures in hospitals to improve future antibiotic use. Conclusion: High antibiotic use reflects high rates of infectious diseases observed in Botswana. A number of concerns have been identified, which are being addressed.

RESUMO

Background: Healthcare-associated infections (HAIs) increase morbidity, mortality, length of hospital stay and costs, and should be prevented where possible. In addition, up to 71% of neonates are prone to bloodstream infections (BSI) during intensive care due to a variety of factors. Consequently, the objectives of this study were to estimate the burden of HAIs and possible risk factors in a tertiary hospital in Botswana as well as describe current trends in bacterial isolates from neonatal blood specimen and their antibiotic resistance patterns.Methods: Point Prevalence Survey (PPS) in all hospital wards and a retrospective cross-sectional review of neonatal blood culture and sensitivity test results, with data abstracted from the hospital laboratory database.Results: 13.54% (n = 47) of patients had HAIs, with 48.9% (n = 23) of them lab-confirmed. The highest prevalence of HAIs was in the adult intensive care unit (100% - n = 5), the nephrology unit (50% - n = 4), and the neonatal intensive care unit (41.9% - n = 13). One-fourth of HAIs were site unspecific, 19.1% (n = 9) had surgical site infections (SSIs), 17% (n = 8) ventilator-associated pneumonia/complications, and 10.6% (n = 5) were decubitus ulcer infections. There were concerns with overcrowding in some wards and the lack of aseptic practices and hygiene. These issues are now being addressed through a number of initiatives. Coagulase Negative Staphylococci (CoNS) was the commonest organism (31.97%) isolated followed by Enterococci spp. (18.03%) among neonates. Prescribing of third-generation cephalosporins is being monitored to reduce Enterococci, Pseudomonas and Acinetobacter spp. infections.Conclusions: There were concerns with the rate of HAIs and BSIs. A number of initiatives are now in place in the hospital to reduce these including promoting improved infection prevention and control (IPC) practices and use of antibiotics via focal persons of the multidisciplinary IPC committee. These will be followed up and reported on.

RESUMO

OBJECTIVES: The problem of antimicrobial resistance (AMR) has assumed pandemic dimensions especially among low-and middle-income countries such as Nigeria. Irrational use of currently available antimicrobial agents is a major contributory factor. There remains a paucity of documented information on the determinants of antibiotic prescribing among physicians in Nigeria to guide future strategies to reduce AMR. This study therefore aimed to investigate the patterns and determinants of antibiotic prescribing among doctors in a tertiary hospital in Nigeria as the first step to improve future antibiotic use in hospitals. METHODS: A cross-sectional survey of the determinants of antibiotic prescribing among doctors in the Lagos State University Teaching Hospital, Ikeja, was performed using a structured questionnaire. Information was obtained about the doctors and the factors determining their prescription of antibiotics. The results were summarized using descriptive statistics with Statistical Package for Social Science. RESULTS: Ninety-eight respondents were studied with a mean age of 36.24(9.01) years, a mean duration of practice of 10.68(9.25) years, and mainly males (64.3%). Ninety-seven percent prescribe antibiotics frequently, mostly based on clinical judgment and experience with rare laboratory supports. Factors of cost, drug availability, and information from pharmaceutical representatives influenced antibiotic prescribing. There were indications of nonexistence or nonfunctional institutional policies and guidelines regarding antimicrobial therapies. CONCLUSION: There is an urgent need to institute evidence-based institutional policies and guidelines for improving antimicrobial use among hospitals in Nigeria. This is already being followed up.
