Assessment of prescribing practices at the primary healthcare facilities in Botswana with an emphasis on antibiotics: Findings and implications.

BACKGROUND AND AIMS: Inappropriate drug prescribing has increased especially in developing countries where systems for monitoring medicine use are not well developed. This increases the rate of antimicrobial resistance. The study aim was to assess the prescribing patterns among urban primary health facilities in Botswana to provide future guidance including developing future quality indicators. METHODS: Retrospective data from patients' records between January and December 2013 in 19 clinics were collected in a cross-sectional study. The WHO/International Network for Rational Use of Drugs indicators were used to assess prescribing patterns in the study clinics. RESULTS: Average number of drugs per prescription was 2.8; 78.6% of the prescribed antibiotics were by International Non-proprietary Name and 96.1% complied with the Botswana Essential Drugs List. Overall rate of antibiotic prescribing was high (42.7%) with 14.7%, 5.9% and 1.3% of prescriptions having two, three and four antibiotics, respectively. Systemic antibiotics (JO1C) accounted for 45.4% of prescribed antibiotics of which amoxicillin accounted for 28.4% and metronidazole 14.4% of all antibiotic prescriptions. There was low use of co-amoxiclav (0.3% of all antibiotic prescriptions). Third generation cephalosporins and macrolides accounted for 9.8% and 6.2% of antibiotic prescriptions respectively, with no prescribing of fluoroquinolones. The majority of indications (87%) for antibiotic prescriptions were according to ICD classification. CONCLUSIONS: While most indications for antibiotic prescriptions were based on signs and symptoms according to ICD, antibiotic prescribing rates were high with some conditions not requiring antibiotics because they are viral infections. There is a need to further improve prescribing practices through induction and training of in-service prescribers. An effective management tool for monitoring antibiotic prescribing practices at Primary Health Care facilities should be designed and implemented, including developing robust quality indicators.

Tackling antimicrobial resistance across sub-Saharan Africa: current challenges and implications for the future.

INTRODUCTION: Antimicrobial resistance (AMR) is a concern as this increases morbidity, mortality, and costs, with sub-Saharan Africa having the highest rates globally. Concerns with rising AMR have resulted in international, Pan-African, and country activities including the development of national action plans (NAPs). However, there is variable implementation across Africa with key challenges persisting. AREAS COVERED: Consequently, there is an urgent need to document current NAP activities and challenges across sub-Saharan Africa to provide future guidance. This builds on a narrative review of the literature. EXPERT OPINION: All surveyed sub-Saharan African countries have developed their NAPs; however, there is variable implementation. Countries including Botswana and Namibia are yet to officially launch their NAPs with Eswatini only recently launching its NAP. Cameroon is further ahead with its NAP than these countries; though there are concerns with implementation. South Africa appears to have made the greatest strides with implementing its NAP including regular monitoring of activities and instigation of antimicrobial stewardship programs. Key challenges remain across Africa. These include available personnel, expertise, capacity, and resources to undertake agreed NAP activities including active surveillance, lack of focal points to drive NAPs, and competing demands and priorities including among donors. These challenges are being addressed, with further co-ordinated efforts needed to reduce AMR.

Coronavirus Disease 2019 (COVID-19) Pandemic across Africa: Current Status of Vaccinations and Implications for the Future.

The introduction of effective vaccines in December 2020 marked a significant step forward in the global response to COVID-19. Given concerns with access, acceptability, and hesitancy across Africa, there is a need to describe the current status of vaccine uptake in the continent. An exploratory study was undertaken to investigate these aspects, current challenges, and lessons learnt across Africa to provide future direction. Senior personnel across 14 African countries completed a self-administered questionnaire, with a descriptive analysis of the data. Vaccine roll-out commenced in March 2021 in most countries. COVID-19 vaccination coverage varied from low in Cameroon and Tanzania and up to 39.85% full coverage in Botswana at the end of 2021; that is, all doses advocated by initial protocols versus the total population, with rates increasing to 58.4% in Botswana by the end of June 2022. The greatest increase in people being fully vaccinated was observed in Uganda (20.4% increase), Botswana (18.5% increase), and Zambia (17.9% increase). Most vaccines were obtained through WHO-COVAX agreements. Initially, vaccination was prioritised for healthcare workers (HCWs), the elderly, adults with co-morbidities, and other at-risk groups, with countries now commencing vaccination among children and administering booster doses. Challenges included irregular supply and considerable hesitancy arising from misinformation fuelled by social media activities. Overall, there was fair to reasonable access to vaccination across countries, enhanced by government initiatives. Vaccine hesitancy must be addressed with context-specific interventions, including proactive programmes among HCWs, medical journalists, and the public.

Antimicrobial utilization research and activities in Botswana, the past, present and the future.

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.

Point prevalence study of antimicrobial use among hospitals across Botswana; findings and implications.

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.

Ongoing initiatives to improve the use of antibiotics in Botswana: University of Botswana symposium meeting report.

BACKGROUND AND OBJECTIVE: There are ongoing initiatives in Botswana to enhance appropriate antibiotic use. The objective of this meeting was to discuss ongoing initiatives in Botswana since February 2016 to improve antibiotic use. Subsequently, use the findings to refine national and local action plans. METHOD: Presentation and review of ongoing initiatives. RESULTS: There was a high rate of antibiotic prescribing among ambulatory care patients in the public sector (42.7%) as well as for patients with upper respiratory tract infections in the private sector (72.9%). Prophylactic antibiotics were given to 73.3% of surgical patients to reduce surgical site infections (SSIs) in a leading tertiary hospital in Botswana; however, SSIs at 9% of patients can be reduced further with better timing of antibiotic prophylaxis. To date, 711 patients have been enrolled into the national point prevalence study. Highlighted concerns included limited ordering and use of sensitivity tests despite functional laboratories, as well as concerns with missed doses of antibiotics across most hospitals. CONCLUSION: A number of issues and concerns regarding antibiotic use were highlighted. Activities are ongoing across sectors to address identified concerns.
