RESUMO
BACKGROUND: Tuberculosis (TB) is a leading cause of death among children living with HIV (CLHIV). Isoniazid preventive therapy (IPT) reduces the incidence of TB by 70% and mortality by 50% among CLHIV. However, in most developing countries including Tanzania, the uptake of IPT is suboptimal, below the 90% WHO-global uptake target. We assessed the factors associated with IPT uptake among CLHIV in Mwanza region, Tanzania. METHODS: This was a multicenter facility-based cross-sectional study among CLHIV aged 1 to 10 years in seven districts of Mwanza region, Tanzania from 1st November 2021 to 20th January 2022. Data were collected using a structured interview-administered questionnaire including information on children and caregivers' demographics, caregivers' health related information and children's clinical information. Our outcome variable was uptake of IPT, defined as initiation on IPT either during the time of the study or within past three years before this study We conducted modified Poisson regression to assess the association between IPT uptake and selected exposures in Stata version 15.0. RESULTS: A total of 415 CLHIV were enrolled, the median age of the children was 7 years (Interquartile range: 5-8). The uptake of IPT was 91% (n = 377). The majority of children's caregivers were HIV positive (86%, n = 387) and were aware about IPT (63.6%, n = 264). Factors associated with IPT uptake included; having an employed caregiver [Adjusted Prevalence Ratio (aPR): 1.06 95% Confidence Interval (CI): 1.00-1.13] and attending the ART clinic every month [aPR: 1.00; 95% CI: 0.87-1.00] . CONCLUSIONS: The uptake of IPT uptake among CLHIV in Mwanza, Tanzania exceeds the global WHO-target of ≥ 90%. Monthly ART clinic visits could be essential in promoting IPT uptake among CLHIV.

Currently, highly active antiretroviral therapy is unable to cure HIV/AIDS because of HIV latency. This study aimed at documenting medicinal plants used in the management of HIV/AIDS in Eastern Uganda so as to identify phytochemicals with HIV latency reversing potential. An ethnobotanical survey was conducted across eight districts in Eastern Uganda. Traditional medicine practitioners were interviewed using semi-structured questionnaires. Qualitative and quantitative phytochemical tests were respectively, performed to determine the presence and quantity of phytochemicals in frequently mentioned plant species. Data were analysed and presented using descriptive statistics and Informant Consensus Factor (ICF). Twenty-one plant species from fourteen plant families were reported to be used in the management of HIV/AIDS. Six plant species with the highest frequency of mention were: Zanthoxylum chalybeum, Gymnosporia senegalensis, Warbugia ugandensis, Leonatis nepetifolia, Croton macrostachyus and Rhoicissus tridentata. Qualitative phytochemical analysis of all the six most frequently mentioned plant species revealed the presence of flavonoids, tannins, terpenoids, alkaloids and phenolics. Quantitative analysis revealed the highest content of flavonoids in L. nepetifolia (20.4 mg/g of dry extract) while the lowest content was determined in C. macrostachyus (7.1 mg/g of dry extract). On the other hand, the highest content of tannins was observed in L. nepetifolia. (199.9 mg/g of dry extract) while the lowest content was found in R. tridentata. (42.6 mg/g of dry extract). Medicinal plants used by traditional medicine practitioners in Eastern Uganda to manage HIV/AIDS are rich in phytochemicals including flavonoids and tannins. Further studies to evaluate the HIV-1 latency reversing ability of these phytochemicals are recommended to discover novel molecules against HIV/AIDS.
RESUMO
BACKGROUND: Diabetes affects 75% of people in low-income countries, where conventional drugs like metformin are available, but newer drugs like alpha-glucosidase inhibitors are not accessible to most Southern African patients. AIM: To evaluate the α-glucosidase and α-amylase inhibitory activities of fractionated aqueous extracts of Kigelia africana fruit (KAFE) and their phytochemical fingerprints using gas chromatography-mass spectrometry (GC-MS). MATERIALS AND METHODS: We studied K. africana fruit fractions' inhibitory effects on alpha-glucosidase and alpha-amylase using bioassay-guided fractionation, and analyzed their phytochemical profiles with GC-MS. KEY FINDINGS: Both the aqueous extract and ethyl acetate fraction of the aqueous extract exhibited a low dose-dependent inhibition of alpha-amylase activity (p < 0.0001). At a concentration of 500 µg/mL, the aqueous extract caused an alpha-glucosidase inhibition of 64.10 ± 2.7%, with an estimated IC50 of 193.7 µg/mL, while the ethyl acetate fraction had an inhibition of 89.82 ± 0.8% and an estimated IC50 of 10.41 µg/mL. The subfraction G, which had the highest alpha-glucosidase inhibitory activity at 85.10 ± 0.7%, had significantly lower activity than the ethyl acetate fraction. The most bioactive fraction was found to contain 11"(2-cyclopenten-1-yl) undecanoic acid, ( +)- and cyclopentane undecanoic acid as well as the indole alkaloids Akuammilan-17-ol-10-methoxy, N-nitroso-2-methyl-oxazolidine and epoxide Oxirane2.2â³ -(1.4-butanediyl) bis-. CONCLUSION: The K. africana fruit fraction demonstrated significant alpha-glucosidase inhibitory activity, while its alpha-amylase inhibitory activity was limited. This study suggests a potential natural alpha-glucosidase inhibitor and phytocompounds that could serve as leads for developing antidiabetic agents.

Albizia coriaria (Fabaceae) crude extracts are key ingredients of several licensed and unlicensed herbal products in East Africa. However, there is limited and often contradicting information regarding its toxicity. We therefore evaluated the acute and subacute toxicity of the ethanolic stem bark extract of A. coriaria in mature healthy Wistar albino rats following Lorke's method and OECD guidelines 407. The LD50 of the ethanolic stem bark extract of A. coriaria was 2000 mg/kg. The acute toxicity signs observed included piloerection, hyperventilation, lethargy, and loss of righting reflex. There was a significant increase in aspartate aminotransferase, alkaline phosphatase, red blood cells and haemoglobin in rats after 28 days at the dose of 500 mg/kg. Histological analyses revealed multifocal random parenchymal necrosis and scattered periportal mononuclear inflammatory cells infiltration in the liver, interstitial nephritis in the kidney and multifocal lymphoid accumulation in the peribronchiolar and perivascular lung tissue at 500 mg/kg. The ethanolic stem bark of A. coriaria was therefore moderately toxic to the rats when administered in a single high oral dose within 24 h. The extract caused a dose dependent toxicity with significant damage to the kidney, liver and lung tissues at a dose of 500 mg/kg after 28 days. Herbal medicines containing A. coriaria extracts should be consumed cautiously due to likelihood of toxicity particularly at higher doses greater than 500 mg/kg.
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.

There are serious concerns with rising antimicrobial resistance (AMR) across countries increasing morbidity, mortality and costs. These concerns have resulted in a plethora of initiatives globally and nationally including national action plans (NAPs) to reduce AMR. Africa is no exception, especially with the highest rates of AMR globally. Key activities in NAPs include gaining a greater understanding of current antimicrobial utilization patterns through point prevalence surveys (PPS) and subsequently instigating antimicrobial stewardship programs (ASPs). Consequently, there is a need to comprehensively document current utilization patterns among hospitals across Africa coupled with ASP studies. In total, 33 PPS studies ranging from single up to 18 hospitals were documented from a narrative review with typically over 50% of in-patients prescribed antimicrobials, up to 97.6% in Nigeria. The penicillins, ceftriaxone and metronidazole, were the most prescribed antibiotics. Appreciable extended prescribing of antibiotics up to 6 days or more post-operatively was seen across Africa to prevent surgical site infections. At least 19 ASPs have been instigated across Africa in recent years to improve future prescribing utilizing a range of prescribing indicators. The various findings resulted in a range of suggested activities that key stakeholders, including governments and healthcare professionals, should undertake in the short, medium and long term to improve future antimicrobial prescribing and reduce AMR across Africa.
RESUMO
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.
RESUMO
BACKGROUND: In Namibia, overuse of medically important antibiotics in animals is common and is a considerable driver of antimicrobial resistance. The study aims to analyze policies, resistance patterns, and consumption of these antibiotics used in animals in Namibia. RESEARCH DESIGN AND METHODS: A scoping review and retrospective descriptive analysis of policies, resistance patterns, and use of these antibiotics in Namibia was conducted, and assessed against the Access, Watch and Reserve (AWaRe) antimicrobial use guidance. RESULTS: Of the forty-five antibiotic products registered for use in animals, 77.8% are Access antibiotics, 68.9% are broad-spectrum and 60% are over-the-counter antibiotics - mainly tetracyclines, penicillins and sulfonamides. There is misalignment of antibiotic use policies for animals and humans and currently no guideline for antibiotic use in animals. Most medically important antibiotics are indicated for control of gastrointestinal (77.7%), musculoskeletal (71.1%), and respiratory (46.7%) infections, and for growth promotion (4.4%). There is high resistance to AWaRe Access antibiotics- sulfonamides (19.5-100%), tetracyclines (56-100%), and penicillin (13.5-100%). CONCLUSION: Whilst Namibia banned the use of antibiotics in farming, current policy frameworks are inconsistent across sectors, and promote overuse of broad-spectrum important antibiotics in animals. A multi-sectoral one health approach is required to harmonize antibiotic use policies and reduce resistance.

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.

BACKGROUND: Tobacco smoking is a considerable barrier to reducing morbidity and mortality associated with non-communicable diseases (NCDs). However, few studies in sub-Saharan Africa have explored access to smoking cessation programs including smoking cessation pharmacotherapy (SCP). This needs to be addressed given the growing burden of NCDs across sub-Saharan Africa including Namibia. METHODS: Multi-facility cross-sectional survey among physicians in both public and private sectors in Namibia. RESULTS: Of the 106 physicians recruited, 69% practiced in public health facilities and 92% were nonsmokers. Sixty-seven percent offer smoking cessation services, with 64% of these offering SCP. This was mainly nicotine replacement therapy (53%) and bupropion SR (41%). Overall, all physicians had a low knowledge score of SCP (<50%). The mean knowledge score though was 77% lower among physicians in public versus private sectors (OR = 0.23, 95%CI: 0.14-0.35, p < 0.001). Principal barriers to prescribing SCP were inadequate knowledge and/or lack of smoking cessation guidelines. This is not surprising with SCP medicines not currently listed within the public medicine list in Namibia. CONCLUSION: Despite good attitudes toward SCP, there are concerns with physicians' knowledge and practices especially in the public sector. There is an urgent need to address this and integrate services to reduce NCDs in Namibia.

BACKGROUND: Multiple measures introduced early to restrict COVID-19 have dramatically impacted the teaching of medical and pharmacy students, exacerbated by the lack of infrastructure and experience with e-learning at the start of the pandemic. In addition, the costs and reliability of the Internet across Africa pose challenges alongside undertaking clinical teaching and practical programmes. Consequently, there is a need to understand the many challenges and how these were addressed, given increasingly complex patients, to provide future direction. METHOD: An exploratory study was conducted among senior-level medical and pharmacy educators across Africa, addressing four key questions, including the challenges resulting from the pandemic and how these were dealt with. RESULTS: Staff and student members faced multiple challenges initially, including adapting to online learning. In addition, concerns with the lack of equipment (especially among disadvantaged students), the costs of Internet bundles, and how to conduct practicals and clinical teaching. Multiple activities were undertaken to address these challenges. These included training sessions, developing innovative approaches to teaching, and seeking ways to reduce Internet costs. Robust approaches to practicals, clinical teaching, and assessments have been developed. CONCLUSIONS: Appreciable difficulties to teaching arising from the pandemic are being addressed across Africa. Research is ongoing to improve education and assessments.
RESUMO
BACKGROUND: Resilient pharmaceutical systems and supply chains are critical in the control of COVID-19, a pandemic that has mostly devastated public health systems and livelihoods in resource-limited countries in sub-Saharan Africa. OBJECTIVE: To evaluate the impact of COVID-19 on pharmaceutical systems and supply chain in a resource-limited setting. METHODS: A descriptive qualitative survey using a phenomenological approach was conducted among key informants in the public and private pharmaceutical sectors of Namibia. Data were collected on the perceived impact of COVID-19 pandemic on the supply chain, as well as access and availability of essential medicines among the distributors and points of care in the private and public sectors. Qualitative themes of the impact were analyzed using Tesch's approach. RESULTS: Of the 21 key-informants, 57.1% were female and 85% were from the private versus the public pharmaceutical sector. Overall, key informants reported a negative impact on access and availability of essential medicines, particularly sanitation and hygiene products, and antimicrobials. Most medicine outlets, experienced longer lead times, attributed to reduced inter-country transportation of goods and services and limited in-country capacity and capabilities to manufacture. The main thematic challenges included bureaucratic bottlenecks and lack of emergency readiness of the medicine's logistics supply chain in Namibia. CONCLUSION: COVID-19 pandemic aggravated the inequitable access to essential medicines in the public and private sectors of Namibia. Governments in resource-limited countries need to strengthen in-country Private-Public Partnerships as well as regional treaties for Universal Health Coverage in context of the COVID-19 pandemic.
RESUMO
Antimicrobial resistance (AMR) is a high priority across countries as it increases morbidity, mortality and costs. Concerns with AMR have resulted in multiple initiatives internationally, nationally and regionally to enhance appropriate antibiotic utilization across sectors to reduce AMR, with the overuse of antibiotics exacerbated by the COVID-19 pandemic. Effectively tackling AMR is crucial for all countries. Principally a narrative review of ongoing activities across sectors was undertaken to improve antimicrobial use and address issues with vaccines including COVID-19. Point prevalence surveys have been successful in hospitals to identify areas for quality improvement programs, principally centering on antimicrobial stewardship programs. These include reducing prolonged antibiotic use to prevent surgical site infections. Multiple activities centering on education have been successful in reducing inappropriate prescribing and dispensing of antimicrobials in ambulatory care for essentially viral infections such as acute respiratory infections. It is imperative to develop new quality indicators for ambulatory care given current concerns, and instigate programs with clear public health messaging to reduce misinformation, essential for pandemics. Regular access to effective treatments is needed to reduce resistance to treatments for HIV, malaria and tuberculosis. Key stakeholder groups can instigate multiple initiatives to reduce AMR. These need to be followed up.
RESUMO
Aim: Global expenditure on medicines is rising up to 6% per year driven by increasing prevalence of non-communicable diseases (NCDs) and new premium priced medicines for cancer, orphan diseases and other complex areas. This is difficult to sustain without reforms. Methods: Extensive narrative review of published papers and contextualizing the findings to provide future guidance. Results: New models are being introduced to improve the managed entry of new medicines including managed entry agreements, fair pricing approaches and monitoring prescribing against agreed guidance. Multiple measures have also successfully been introduced to improve the prescribing of established medicines. This includes encouraging greater prescribing of generics and biosimilars versus originators and patented medicines in a class to conserve resources without compromising care. In addition, reducing inappropriate antibiotic utilization. Typically, multiple measures are the most effective. Conclusion: Multiple measures will be needed to attain and retain universal healthcare.

BACKGROUND: Sub-Saharan Africa, a region faced with a double challenge of infectious and non-communicable diseases requires strengthening of hospital pharmacy practice to improve treatment outcomes and patient safety. OBJECTIVES: The objectives of this study were to assess the current state of pharmacy practice in hospitals in Namibia and to identify opportunities for expanding pharmacists' role in addressing public health challenges and improving medicines use outcomes. METHODS: A survey utilized FIP's self-assessment tool to evaluate current hospital pharmacy practice in Namibia against best practices articulated in the Basel Statements. The study was conducted among hospital pharmacists across Namibia. Quantitative and qualitative data were analysed using descriptive statistics and thematic analysis. KEY FINDINGS: The study was conducted in 24 hospital pharmacies across Namibia, the majority of which were public facilities (67%). Overall, current hospital pharmacy practice activities are focused on medicine procurement, preparation and distribution. The main barriers to optimal hospital pharmacy services are associated with limited human resources and collaboration across healthcare providers, as well as policy gaps. CONCLUSIONS: There is a strong desire among hospital pharmacists to expand their contributions to improving medicines outcomes and solving public health problems. Namibia's pharmacy educational system is a strength and should be utilized to continue advancing hospital pharmacy practice and medicines use. Therapeutics committees are usually part of each hospital's structure and can be very effective for hospital-based policy change. The opportunity exists to optimize pharmacists' contributions by utilizing the local therapeutics committees in combination with the educational system to advance hospital pharmacy practice in Namibia.

SETTING: In Namibia, the burden of mental illnesses is estimated at 25.6% and is expected to double by 2025. Few studies in sub-Saharan Africa estimate the consumption rates of psychotropic medicines as a proxy of irrational use. AIM: The consumption rate of psychotropic medicines at a referral hospital was determined. METHODS: A hospital-based retrospective medicine utilization analysis of Facility Electronic Stock Card (FESC) psychotropic medication was conducted at Intermediate Hospital Katutura over a 7 year period, 2011-2017. Data on consumption and expenditure on psychotropic medicines were abstracted from FESC and analysed using descriptive statistics in SPSS v22. The main outcomes were consumption rates, daily Defined Dose, (DDD) and/or expenditure. RESULTS: Of the 580 351,4 DDD of psychotropic medicines consumed, 84% were anti-psychotics, 9.2% anti-depressants and 6.8% anxiolytics. Anti-psychotics (48.8%) and anxiolytics (47.9%) had the highest consumption by cost relative to anti-depressants (3.3%). The most consumed antidepressants were imipramine (62%) by DDD and fluoxetine (55.8%) by cost. The most consumed anti-psychotics were chlorpromazine (74.6%) by DDD and haloperidol (68.4%) by cost respectively. Diazepam (79.4%) and hydroxyzine (94.2%) were most consumed sedative-hypnotics by DDD and cost respectively. CONCLUSION: The consumption of new psychotropics contributes to higher costs. There is need for cost-effectiveness analysis of new versus conventional psychotropics to optimize treatment, outcomes and costs.

BACKGROUND: The COVID-19 pandemic has already claimed considerable lives. There are major concerns in Africa due to existing high prevalence rates for both infectious and non-infectious diseases and limited resources in terms of personnel, beds and equipment. Alongside this, concerns that lockdown and other measures will have on prevention and management of other infectious diseases and non-communicable diseases (NCDs). NCDs are an increasing issue with rising morbidity and mortality rates. The World Health Organization (WHO) warns that a lack of nets and treatment could result in up to 18 million additional cases of malaria and up to 30,000 additional deaths in sub-Saharan Africa. OBJECTIVE: Document current prevalence and mortality rates from COVID-19 alongside economic and other measures to reduce its spread and impact across Africa. In addition, suggested ways forward among all key stakeholder groups. OUR APPROACH: Contextualise the findings from a wide range of publications including internet-based publications coupled with input from senior-level personnel. ONGOING ACTIVITIES: Prevalence and mortality rates are currently lower in Africa than among several Western countries and the USA. This could be due to a number of factors including early instigation of lockdown and border closures, the younger age of the population, lack of robust reporting systems and as yet unidentified genetic and other factors. Innovation is accelerating to address concerns with available equipment. There are ongoing steps to address the level of misinformation and its consequences including fines. There are also ongoing initiatives across Africa to start addressing the unintended consequences of COVID-19 activities including lockdown measures and their impact on NCDs including the likely rise in mental health disorders, exacerbated by increasing stigma associated with COVID-19. Strategies include extending prescription lengths, telemedicine and encouraging vaccination. However, these need to be accelerated to prevent increased morbidity and mortality. CONCLUSION: There are multiple activities across Africa to reduce the spread of COVID-19 and address misinformation, which can have catastrophic consequences, assisted by the WHO and others, which appear to be working in a number of countries. Research is ongoing to clarify the unintended consequences given ongoing concerns to guide future activities. Countries are learning from each other.
RESUMO
Namibia has previously relied on external training of pharmacists but began in-country training in 2011. In response to an identified need for postgraduate clinical pharmacy development and training in the country, a Master's degree was set up at the University of Namibia in 2016. The country has a considerable health burden of HIV and TB as well as a shortage of healthcare professionals. A UK clinical diploma model was adapted to meet the specific needs of the country and wider region, ensuring students could access the course over a sparsely populated, but large geographical spread, in addition to providing work-based learning, embedding research skills for future development, and focusing on the health needs of Namibia. The course uses online learning platforms and contact sessions to cover both knowledge and skill acquisition throughout the 3 years of the course. UK and US clinical pharmacists are utilised to provide specialist input, both remotely and within student workplaces, and further support has come from collaborations, including cross-site visits, with the UK-based pharmacy school whose diploma model was adapted. Challenges have included a shortage of clinical mentors, also compounding the students' difficulty in visualising their future roles, as well as lone practitioners finding it hard to attend all contact sessions. The initial dropout rates of earlier cohorts have since reduced with greater understanding of the programme, and enthusiasm for the course remains high. The aim for the Master's is to train students to become competent clinical pharmacists, thus having the knowledge and skills to mentor future cohorts of the course, as well as expanding the specialty within the country.

Background The World Health Organization estimates that over 50% medicines are prescribed inappropriately and the main driver of antimicrobial resistance globally. There have only been a limited number of studies evaluating prescribing patterns against national standard treatment guidelines (STGs) in sub-Saharan African countries including Namibia. This is important given the high prevalence of both infectious and non-infectious diseases in sub-Saharan Africa alongside limited resources. Objective Our aim was to assess prescribing practices and drivers of compliance to National guidelines among public health care facilities in Namibia to provide future guidance. Setting Three levels of public healthcare in Namibia. Method A mixed method approach including patient exit and prescriber interviews at three levels of health care in Namibia, i.e. hospital, health centre and clinic. Main outcome measures Medicine prescribing indicators, compliance to and attitudes towards National guidelines. Results Of the 1243 prescriptions analysed, 73% complied with the STGs and 69% had an antibiotic. Of the 3759 medicines (i.e. mean of 3.0 ± 1.1) prescribed, 64% were prescribed generically. The vast majority of prescribers were aware of, and had access to, the Namibian STGs (94.6%), with the majority reporting that the guidelines are easy to use and they regularly refer to them. The main drivers of compliance to guidelines were programmatic, that is access to up-to date objective guidelines, support systems for continued education on their use, and ease of referencing. Lack of systems to regulate noncompliance impacted on their use. Conclusion Whilst the findings were encouraging, ongoing concerns included limited prescribing of generic medicines and high use of antibiotics. A prescribing performance management system should be introduced to improve and monitor compliance to prescribing guidelines in public healthcare.

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.
