Funding and financial sustainability of pharmacovigilance: suggested models for funding pharmacovigilance in resource-limited African countries.

Background: An important factor hindering the growth of pharmacovigilance (PV) in resource-limited settings is the lack of adequate funds to establish a functional National Pharmacovigilance System. Consequently, the crucial function of monitoring and ensuring the availability of safe medicines in these settings cannot be guaranteed considering the peculiarities of diseases and medicines used. Objectives: The objective of this paper is to provide an overview as to the availability of potential sources of funds, which could be explored to ensure Medicine Safety and to proffer a potential framework likely to ensure sustainable funding of PV in Africa. Methods/processes: The process of developing this framework entailed a review of PV financing in some developed economies, a landscape study of funding of PV in some African countries, an in-depth understanding of the PV system and the organisational structure and nexus between the regulatory agencies and National Pharmacovigilance Centre. Critical points for consideration included the sources of funds, revenue pool, the disbursement of funds, budgeting and expenditure profile and the legal framework. Consultative meetings, webinars and interviews with experts were carried out. Results: The findings showed that most of the PV systems were mainly integrated into the regulatory agencies regarding operational and fiscal governance with few facilities being independent of the regulatory agencies. The main source of funding was from the government with significant donor funding which is ad hoc and non-sustainable. Several potential sources were identified but yet to be exploited. There were no legal provisions for PV financing. A framework likely to ensure sustainable PV financing is suggested to capture all available sources of funding, mine the potential sources providing a sizeable pool of revenue to address its activities and enabling legal framework which will engender autonomy. Furthermore, it will address the nexus between the regulatory agencies and the PV outfits, thus enabling appropriate share of resources and blockage of diversions. Conclusion: In all, addressing the various elements identified in this study and providing the legal provisions which guarantees some degree of autonomy will provide a sustainable mechanism for PV funding in the resource-limited setting of Africa.

Funding models for pharmacovigilance in resource-limited African countries An important factor hindering the growth of pharmacovigilance (PV) in resource-limited settings following their entry into the WHO Programme of International Drug Monitoring is the lack of adequate funds to establish a functional National Pharmacovigilance System. This article provides an overview of various potential sources of funds in these settings and how they can be harnessed to fund PV. We undertook a review of PV financing in developed settings and carried out a landscape study of funding of PV in some African countries, as well as having an in-depth understanding of the PV system and the organisational structure. The nexus between the regulatory agencies and National Pharmacovigilance Centre was noted. We took into account the sources of funds, revenue pool, the disbursement of funds, budgeting and expenditure profile and the legal framework for the different African countries. We also identified the prevalent and potential sources of funds for PV. Consultative meetings, webinars and interviews with experts in PV were carried out as well. We discovered that most of the PV facilities were mainly integrated into the regulatory agencies regarding operational and fiscal governance with few facilities being independent of the regulatory agencies. The main source of funding was from the government with significant donor funding which is ad hoc and non-sustainable. Several potential sources were identified but yet to be exploited. There were no legal provisions for PV financing. We have now proposed funding models that may lead to increased revenue for PV in these countries as well as suggesting that a legal framework be provided to guarantee sustainability and address the nexus between the regulatory agencies and the PV outfits to ensure an appropriate share of resources and blocking diversions.

A qualitative assessment of stakeholder perspectives on barriers and facilitators to emergency care delays in Northern Tanzania through the Three Delays.

Introduction: Emergency conditions cause a significant burden of death and disability, particularly in developing countries. Prehospital and Emergency Medical Services (EMS) are largely nonexistent throughout Tanzania and little is known about the community's barriers to accessing emergency care. The objective of this study was to better understand local community stakeholder perspectives on barriers, facilitators, and potential solutions surrounding emergency care in the Kilimanjaro region through the Three Delays Model framework. Methods: A qualitative assessment of local stakeholders was conducted through semi-structured focus group discussions (FGDs) from February to June 2021 with five separate groups: hospital administrators, emergency hospital workers, police personnel, fire brigade personnel, and community health workers. FGDs were conducted in Kiswahili, audio recorded, and translated to English verbatim. Two research analysts separately coded the first two FGDs using both inductive and deductive thematic analysis. A final codebook was then created to analyze the remaining FGDs. Results: A total of 24 participants were interviewed. Thematic analysis revealed that participants identified significant barriers within the Three Delays Model as well as identified an additional delay centered on community members and first aid provision. Perceived delays in the decision to seek care, the first delay, were financial constraints and the lack of community education on emergency conditions. Limited infrastructure and reduced transportation access were thought to contribute to the second delay. Potential barriers to receiving timely appropriate care, the third delay, included upfront payments required by hospitals and emergency department intake delays. Suggested solutions focused on increasing education and improving communication and infrastructure. Conclusion: The findings outline barriers to accessing emergency care from a stakeholder perspective. These themes can support recommendations for further strengthening of the prehospital and emergency care system. Due to logistical constraints, emergency care workers interviewed were all from one hospital and patients were not included.

Brief Report: Task-Shifting "Gold Standard" Clinical Assessment and Safety Planning for Suicide Risk Among People Living With HIV: A Feasibility and Fidelity Evaluation in Tanzania.

BACKGROUND: Suicide is a leading cause of death among people living with HIV (PLWH) worldwide, with suicide deaths occurring twice as frequently among PLWH than among the general public. In Tanzania, resources for mental health care are sorely lacking, with 55 psychiatrists and psychologists providing treatment for 60 million people. In light of this shortage, nonspecialists play a crucial role. The objective of this study was to assess feasibility of implementing task-shifted screening, assessment, and safety planning for suicide risk among PLWH. SETTING: Two adult HIV clinics in Kilimanjaro, Tanzania. METHODS: Registered professional nurses in the HIV clinics were trained to administer brief screening of suicidal ideation in the past month. Patients experiencing suicidal ideation were referred to bachelor's-level counselors for further assessment and safety planning, supervised by specialist providers who reviewed audio recordings for quality assurance. RESULTS: During 180 days of implementation, nurses screened patients attending 2745 HIV appointments. Sixty-one (2.2%) endorsed suicidal ideation and were linked to further assessment and safety planning. We cross-checked screening with clinic attendance logs on 7 random days and found high fidelity to screening (206 of 228 screened, 90%). Quality assurance ratings demonstrated key assessment pieces were consistently completed (mean = 9.3/10 possible), with "Good" to "Excellent" counseling skills (mean = 23.7/28) and "Good" to "Excellent" quality (mean = 17.1/20), including appropriate referral for higher levels of care. CONCLUSIONS: Brief screening can be implemented and paired with task-shifted counseling to facilitate high-quality assessment of suicide risk. This model shows excellent potential to extend mental health services for PLWH in low-resource settings.

How public health crises expose systemic, day-to-day health inequalities in low- and-middle income countries: an example from East Africa.

BACKGROUND: The current Coronavirus disease pandemic reveals political and structural inequities of the world's poorest people who have little or no access to health care and yet the largest burdens of poor health. This is in parallel to a more persistent but silent global health crisis, antimicrobial resistance (AMR). We explore the fundamental challenges of health care in humans and animals in relation to AMR in Tanzania. METHODS: We conducted 57 individual interviews and focus groups with providers and patients in high, middle and lower tier health care facilities and communities across three regions of Tanzania between April 2019 and February 2020. We covered topics from health infrastructure and prescribing practices to health communication and patient experiences. RESULTS: Three interconnected themes emerged about systemic issues impacting health. First, there are challenges around infrastructure and availability of vital resources such as healthcare staff and supplies. Second, health outcomes are predicated on patient and provider access to services as well as social determinants of health. Third, health communication is critical in defining trusted sources of information, and narratives of blame emerge around health outcomes with the onus of responsibility for action falling on individuals. CONCLUSION: Entanglements between infrastructure, access and communication exist while constraints in the health system lead to poor health outcomes even in 'normal' circumstances. These are likely to be relevant across the globe and highly topical for addressing pressing global health challenges. Redressing structural health inequities can better equip countries and their citizens to not only face pandemics but also day-to-day health challenges.

Performance Assessment of the Universal Vital Assessment Score vs Other Illness Severity Scores for Predicting Risk of In-Hospital Death Among Adult Febrile Inpatients in Northern Tanzania, 2016-2019.

Importance: Severity scores are used to improve triage of hospitalized patients in high-income settings, but the scores may not translate well to low- and middle-income settings such as sub-Saharan Africa. Objective: To assess the performance of the Universal Vital Assessment (UVA) score, derived in 2017, compared with other illness severity scores for predicting in-hospital mortality among adults with febrile illness in northern Tanzania. Design, Setting, and Participants: This prognostic study used clinical data collected for the duration of hospitalization among patients with febrile illness admitted to Kilimanjaro Christian Medical Centre or Mawenzi Regional Referral Hospital in Moshi, Tanzania, from September 2016 through May 2019. All adult and pediatric patients with a history of fever within 72 hours or a tympanic temperature of 38.0 °C or higher at screening were eligible for enrollment. Of 3761 eligible participants, 1132 (30.1%) were enrolled in the parent study; of those, 597 adults 18 years or older were included in this analysis. Data were analyzed from December 2019 to September 2021. Exposures: Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), quick Sequential Organ Failure Assessment (qSOFA), Systemic Inflammatory Response Syndrome (SIRS) assessment, and UVA. Main Outcomes and Measures: The main outcome was in-hospital mortality during the same hospitalization as the participant's enrollment. Crude risk ratios and 95% CIs for in-hospital death were calculated using log-binomial risk regression for proposed score cutoffs for each of the illness severity scores. The area under the receiver operating characteristic curve (AUROC) for estimating the risk of in-hospital death was calculated for each score. Results: Among 597 participants, the median age was 43 years (IQR, 31-56 years); 300 participants (50.3%) were female, 198 (33.2%) were HIV-infected, and in-hospital death occurred in 55 (9.2%). By higher risk score strata for each score, compared with lower risk strata, risk ratios for in-hospital death were 3.7 (95% CI, 2.2-6.2) for a MEWS of 5 or higher; 2.7 (95% CI, 0.9-7.8) for a NEWS of 5 or 6; 9.6 (95% CI, 4.2-22.2) for a NEWS of 7 or higher; 4.8 (95% CI, 1.2-20.2) for a qSOFA score of 1; 15.4 (95% CI, 3.8-63.1) for a qSOFA score of 2 or higher; 2.5 (95% CI, 1.2-5.2) for a SIRS score of 2 or higher; 9.1 (95% CI, 2.7-30.3) for a UVA score of 2 to 4; and 30.6 (95% CI, 9.6-97.8) for a UVA score of 5 or higher. The AUROCs, using all ordinal values, were 0.85 (95% CI, 0.80-0.90) for the UVA score, 0.81 (95% CI, 0.75-0.87) for the NEWS, 0.75 (95% CI, 0.69-0.82) for the MEWS, 0.73 (95% CI, 0.67-0.79) for the qSOFA score, and 0.63 (95% CI, 0.56-0.71) for the SIRS score. The AUROC for the UVA score was significantly greater than that for all other scores (P < .05 for all comparisons) except for NEWS (P = .08). Conclusions and Relevance: This prognostic study found that the NEWS and the UVA score performed favorably compared with other illness severity scores in predicting in-hospital mortality among a hospitalized cohort of adults with febrile illness in northern Tanzania. Given its reliance on readily available clinical data, the UVA score may have utility in the triage and prognostication of patients admitted to the hospital with febrile illness in low- to middle-income settings such as sub-Saharan Africa.

"He Who Relies on His Brother's Property Dies Poor": The Complex Narratives of Livestock Care in Northern Tanzania.

Background: Endemic zoonoses have important impacts for livestock-dependent households in East Africa. In these communities, people's health and livelihoods are severely affected by livestock disease losses. Understanding how livestock keepers undertake remedial actions for livestock illness has the potential for widespread benefits such as improving health interventions. Yet, studies about livestock and human health behaviours in the global south tend to focus on individual health choices. In reality, health behaviours are complex, and not solely about individualised health experiences. Rather, they are mediated by a range of "upstream" factors (such as unequal provision of services), which are beyond the control of the individual. Methods: This paper presents qualitative research conducted from 2014 to 2019 for a study focused on the Social, Economic, and Environmental Drivers of Zoonoses in Tanzania (SEEDZ). Qualitative data were collected via focus group discussions, community meetings, informal interviews, formal in-depth interviews, observations and surveys that addressed issues of health, disease, zoonotic disease risks, and routes for treatment across 21 villages. Thematic analysis was carried out on in-depth interviews and focus group discussions. Conceptual analyses and observations were made through application of social science theories of health. Findings: Livestock keepers undertake a range of health seeking strategies loosely categorised around self and formal treatment. Two key themes emerged that are central to why people make the decisions they do: access to resources and trust in health care providers. These two issues affect individual sense of agency which impacts their ability to act to improve livestock health outcomes. We suggest that individual choice and agency in veterinary health seeking decisions are only beneficial if health systems can offer adequate care and health equity is addressed. Significance: This study demonstrates the value of in-depth qualitative research which reveals the nuance and complexity of people's decisions around livestock health. Most importantly, it explains why "better" knowledge does not always translate into "better" practise. The paper suggests that acknowledging and addressing these aspects of veterinary health seeking will lead to more effective provision.

Trends in fever case management for febrile inpatients in a low malaria incidence setting of Tanzania.

OBJECTIVES: In 2010, WHO published guidelines emphasising parasitological confirmation of malaria before treatment. We present data on changes in fever case management in a low malaria transmission setting of northern Tanzania after 2010. METHODS: We compared diagnoses, treatments and outcomes from two hospital-based prospective cohort studies, Cohort 1 (2011-2014) and Cohort 2 (2016-2019), that enrolled febrile children and adults. All participants underwent quality-assured malaria blood smear-microscopy. Participants who were malaria smear-microscopy negative but received a diagnosis of malaria or received an antimalarial were categorised as malaria over-diagnosis and over-treatment, respectively. RESULTS: We analysed data from 2098 participants. The median (IQR) age was 27 (3-43) years and 1047 (50.0%) were female. Malaria was detected in 23 (2.3%) participants in Cohort 1 and 42 (3.8%) in Cohort 2 (p = 0.059). Malaria over-diagnosis occurred in 334 (35.0%) participants in Cohort 1 and 190 (17.7%) in Cohort 2 (p < 0.001). Malaria over-treatment occurred in 528 (55.1%) participants in Cohort 1 and 196 (18.3%) in Cohort 2 (p < 0.001). There were 30 (3.1%) deaths in Cohort 1 and 60 (5.4%) in Cohort 2 (p = 0.007). All deaths occurred among smear-negative participants. CONCLUSION: We observed a substantial decline in malaria over-diagnosis and over-treatment among febrile inpatients in northern Tanzania between two time periods after 2010. Despite changes, some smear-negative participants were still diagnosed and treated for malaria. Our results highlight the need for continued monitoring of fever case management across different malaria epidemiological settings in sub-Saharan Africa.

Epidemiology and management of asthma and atopic dermatitis in Sub-Saharan Africa.

Sub-Saharan Africa (SSA) is currently undergoing a transformation process of unprecedented magnitude owing to economic development and urbanization. This process is paralleled by a dramatic increase in prevalence and incidence of noncommunicable diseases. In this article we analyze the current situation with regard to 1 group of the earliest noncommunicable diseases in a person's life, namely, allergies and asthma. This article provides an update on the epidemiology, availability, and access to management strategies by patients experiencing bronchial asthma or atopic dermatitis in SSA. Despite all of the progress, there is still a tremendous need to support education and training, transfer of resources, and cooperation with pharmaceutical and diagnostic companies to achieve adequate treatment and sustainability in SSA with regard to allergy, asthma, and eczema management.

Gut microbiome-mediated metabolism effects on immunity in rural and urban African populations.

The human gut microbiota is increasingly recognized as an important factor in modulating innate and adaptive immunity through release of ligands and metabolites that translocate into circulation. Urbanizing African populations harbor large intestinal diversity due to a range of lifestyles, providing the necessary variation to gauge immunomodulatory factors. Here, we uncover a gradient of intestinal microbial compositions from rural through urban Tanzanian, towards European samples, manifested both in relative abundance and genomic variation observed in stool metagenomics. The rural population shows increased Bacteroidetes, led by Prevotella copri, but also presence of fungi. Measured ex vivo cytokine responses were significantly associated with 34 immunomodulatory microbes, which have a larger impact on circulating metabolites than non-significant microbes. Pathway effects on cytokines, notably TNF-α and IFN-γ, differential metabolome analysis and enzyme copy number enrichment converge on histidine and arginine metabolism as potential immunomodulatory pathways mediated by Bifidobacterium longum and Akkermansia muciniphila.

Performance characteristics and costs of serological tests for brucellosis in a pastoralist community of northern Tanzania.

The control of brucellosis across sub-Saharan Africa is hampered by the lack of standardized testing and the use of tests with poor performance. This study evaluated the performance and costs of serological assays for human brucellosis in a pastoralist community in northern Tanzania. Serum collected from 218 febrile hospital patients was used to evaluate the performance of seven index tests, selected based on international recommendation or current use. We evaluated the Rose Bengal test (RBT) using two protocols, four commercial agglutination tests and a competitive enzyme-linked immunosorbent assay (cELISA). The sensitivity, specificity, positive predictive value, negative predictive value, Youden's index, diagnostic accuracy, and per-sample cost of each index test were estimated. The diagnostic accuracy estimates ranged from 95.9 to 97.7% for the RBT, 55.0 to 72.0% for the commercial plate tests, and 89.4% for the cELISA. The per-sample cost range was $0.69-$0.79 for the RBT, $1.03-$1.14 for the commercial plate tests, and $2.51 for the cELISA. The widely used commercial plate tests performed poorly and cost more than the RBT. These findings provide evidence for the public health value of discontinuing the use of commercial agglutination tests for human brucellosis in Tanzania.

Barriers to implementing antimicrobial stewardship programs in three low- and middle-income country tertiary care settings: findings from a multi-site qualitative study.

BACKGROUND: Antimicrobial resistance has been named as one of the top ten threats to public health in the world. Hospital-based antimicrobial stewardship programs (ASPs) can help reduce antimicrobial resistance. The purpose of this study was to determine perceived barriers to the development and implementation of ASPs in tertiary care centers in three low- and middle-income countries (LMICs). METHODS: Interviews were conducted with 45 physicians at tertiary care hospitals in Sri Lanka (n = 22), Kenya (12), and Tanzania (11). Interviews assessed knowledge of antimicrobial resistance and ASPs, current antimicrobial prescribing practices, access to diagnostics that inform antimicrobial use, receptiveness to ASPs, and perceived barriers to implementing ASPs. Two independent reviewers coded the interviews using principles of applied thematic analysis, and comparisons of themes were made across the three sites. RESULTS: Barriers to improving antimicrobial prescribing included prohibitively expensive antimicrobials, limited antimicrobial availability, resistance to changing current practices regarding antimicrobial prescribing, and limited diagnostic capabilities. The most frequent of these barriers in all three locations was limited drug availability. Many physicians in all three sites had not heard of ASPs before the interviews. Improved education was a suggested component of ASPs at all three sites. The creation of guidelines was also recommended, without prompting, by interviewees at all three sites. Although most participants felt microbiological results were helpful in tailoring antibiotic courses, some expressed distrust of laboratory culture results. Biomarkers like erythrocyte sedimentation rate and c-reactive protein were not felt to be specific enough to guide antimicrobial therapy. Despite limited or no prior knowledge of ASPs, most interviewees were receptive to implementing protocols that would include documentation and consultation with ASPs regarding antimicrobial prescribing. CONCLUSIONS: Our study highlighted several important barriers to implementing ASPs that were shared between three tertiary care centers in LMICs. Improving drug availability, enhancing availability of and trust in microbiologic data, creating local guidelines, and providing education to physicians regarding antimicrobial prescribing are important steps that could be taken by ASPs in these facilities.

Classification and characterisation of livestock production systems in northern Tanzania.

Livestock keepers in sub-Saharan Africa face a range of pressures, including climate change, land loss, restrictive policies, and population increase. Widespread adaptation in response can lead to the emergence of new, non-traditional typologies of livestock production. We sought to characterise livestock production systems in two administrative regions in northern Tanzania, an area undergoing rapid social, economic, and environmental change. Questionnaire and spatial data were collected from 404 livestock-keeping households in 21 villages in Arusha and Manyara Regions in 2016. Multiple factor analysis and hierarchical cluster analysis were used to classify households into livestock production systems based on household-level characteristics. Adversity-based indicators of vulnerability, including reports of hunger, illness, and livestock, land and crop losses were compared between production systems. Three distinct clusters emerged through this process. The ethnic, environmental and livestock management characteristics of households in each cluster broadly mapped onto traditional definitions of 'pastoral', 'agro-pastoral' and 'smallholder' livestock production in the study area, suggesting that this quantitative classification system is complementary to more qualitative classification methods. Our approach allowed us to demonstrate a diversity in typologies of livestock production at small spatial scales, with almost half of study villages comprising more than one production system. We also found indicators of change within livestock production systems, most notably the adoption of crop agriculture in the majority of pastoral households. System-level heterogeneities in vulnerability were evident, with agro-pastoral households most likely to report hunger and pastoral households most likely to report illness in people and livestock, and livestock losses. We demonstrate that livestock production systems can provide context for assessing household vulnerability in northern Tanzania. Policy initiatives to improve household and community well-being should recognise the continuing diversity of traditional livestock production systems in northern Tanzania, including the diversity that can exist at small spatial scales.

"If You Have No Money, You Might Die": A Qualitative Study of Sociocultural and Health System Barriers to Care for Decedent Febrile Inpatients in Northern Tanzania.

Infectious diseases are a leading cause of mortality in low- and middle-income countries (LMICs) despite effective treatments. To study the sociocultural and health system barriers to care, we conducted a qualitative social autopsy study of patients who died from febrile illness in northern Tanzania. From December 2016 through July 2017, we conducted in-depth interviews in Arusha and Kilimanjaro regions with a purposive sample of 20 family members of patients who had died at two regional referral hospitals. Of the deceased patients included in this study, 14 (70%) were adults and 10 (50%) were female. Patients identified their religion as Catholic (12, 60%), Lutheran (six, 30%), and Muslim (two, 10%), and their ethnicity as Chagga (14, 70%) and Sambaa (two, 10%), among others. Family members reported both barriers to and facilitators of receiving health care. Barriers included a perceived lack of capacity of local health facilities, transportation barriers, and a lack of formal referrals to higher levels of care. Family members also reported the cost of health care as a barrier. However, one facilitator of care was access to financial resources via families' social networks-a phenomenon we refer to as social capital. Another facilitator of care was families' proactive engagement with the health system. Our results suggest that further investment in lower level health facilities may improve care-seeking and referral patterns and that future research into the role of social capital is needed to fully understand the effect of socioeconomic factors on healthcare utilization in LMICs.

Mentoring the Mentors: Implementation and Evaluation of Four Fogarty-Sponsored Mentoring Training Workshops in Low-and Middle-Income Countries.

A growing body of evidence highlights the importance of competent mentoring in academic research. We describe the development, implementation, and evaluation of four regional 2-day intensive workshops to train mid- and senior-level investigators conducting public health, clinical, and basic science research across multiple academic institutions in low- and middle-income countries (LMICs) on tools and techniques of effective mentoring. Sponsored by the Fogarty International Center, workshops included didactic presentations, interactive discussions, and small-group problem-based learning and were conducted in Lima, Peru; Mombasa, Kenya; Bangalore, India; and Johannesburg, South Africa, from 2013 to 2016. Mid- or senior-level faculty from multiple academic institutions within each region applied and were selected. Thirty faculty from 12 South America-based institutions, 29 faculty from eight East Africa-based institutions, 37 faculty from 14 South Asia-based institutions, and 36 faculty from 13 Africa-based institutions participated, with diverse representation across disciplines, gender, and academic rank. Discussions and evaluations revealed important comparisons and contrasts in the practice of mentoring, and specific barriers and facilitators to mentoring within each cultural and regional context. Specific regional issues related to hierarchy, the post-colonial legacy, and diversity arose as challenges to mentoring in different parts of the world. Common barriers included a lack of a culture of mentoring, time constraints, lack of formal training, and a lack of recognition for mentoring. These workshops provided valuable training, were among the first of their kind, were well-attended, rated highly, and provided concepts and a structure for the development and strengthening of formal mentoring programs across LMIC institutions.

Prescription and non-prescription antibiotic dispensing practices in part I and part II pharmacies in Moshi Municipality, Kilimanjaro Region in Tanzania: A simulated clients approach.

Antibiotic dispensing without a prescription poses a threat to public health as it leads to excessive antibiotic consumption. Inappropriate antibiotic availability to the community has been documented to be amongst drivers of antimicrobial resistance emergence. Community pharmacies are a source of antibiotics in low and middle-income countries (LMICs). We aimed at assessing antibiotic dispensing practices by community pharmacy retailers in Moshi urban, Kilimanjaro, Tanzania and recommend interventions to improve practice. Using a Simulated Client (SC) Method, an observational cross-sectional survey of antibiotic dispensing practices was conducted from 10th June to 10th July 2017. Data analysis was done using Stata 13 (StataCorp, College Station, TX, USA). A total of 82 pharmacies were visited. Part I pharmacies were 26 (31.71%) and 56 (68.29%) were part II. Overall 92.3% (95% CI 77.8-97.6) of retailers dispensed antibiotics without prescriptions. The antibiotics most commonly dispensed without a prescription were ampiclox for cough (3 encounters) and azithromycin for painful urination (3 encounters). An oral third generation cephalosporin (cefixime) was dispensed once for painful urination without prescription by a part I pharmacy retailer. Out of 21, 15(71.43%) prescriptions with incomplete doses were accepted and had antibiotics dispensed. Out of 68, 4(5.9%) retailers gave instructions for medicine use voluntarily. None of the retailers voluntarily explained drug side-effects. In Moshi pharmacies, a high proportion of antibiotics are sold and dispensed without prescriptions. Instructions for medicine use are rarely given and none of the retailers explain side effects. These findings support the need for a legislative enforcement of prescription-only antibiotic dispensing rules and regulations. Initiation of clinician and community antibiotic stewardship and educational programs on proper antibiotic use to both pharmacists and public by the regulatory bodies are highly needed.

The African Esophageal Cancer Consortium: A Call to Action.

Esophageal cancer is the eighth most common cancer worldwide and the sixth most common cause of cancer-related death; however, worldwide incidence and mortality rates do not reflect the geographic variations in the occurrence of this disease. In recent years, increased attention has been focused on the high incidence of esophageal squamous cell carcinoma (ESCC) throughout the eastern corridor of Africa, extending from Ethiopia to South Africa. Nascent investigations are underway at a number of sites throughout the region in an effort to improve our understanding of the etiology behind the high incidence of ESCC in this region. In 2017, these sites established the African Esophageal Cancer Consortium. Here, we summarize the priorities of this newly established consortium: to implement coordinated multisite investigations into etiology and identify targets for primary prevention; to address the impact of the clinical burden of ESCC via capacity building and shared resources in treatment and palliative care; and to heighten awareness of ESCC among physicians, at-risk populations, policy makers, and funding agencies.

Perceived barriers by health care providers for screening and management of excessive alcohol use in an emergency department of a low-income country.

Annually, alcohol causes 3.3 million deaths; countless more alcohol-related injury patients are treated in emergency departments (EDs) worldwide. Studies show that alcohol-related injury patients reduce their at-risk alcohol-use behavior with a brief negotiational interview (BNI) in the ED. This project aims to identify potential perceived barriers to implementing a BNI in Tanzania. A knowledge, attitude, and practice questionnaire was piloted and administered to all emergency department health care practitioners, including physicians, advanced medical officers, and nurses. The questionnaire included the Perceived Alcohol Stigma (PAS) Scale. The survey was self-administered in English, the language of health care instruction, with a Swahili translation available if preferred. Data were analyzed with relative and absolute frequencies and Spearman's correlation. Thirty-four (100%) health care practitioners completed the survey. Our results found positive attitudes toward addressing alcohol misuse (88%), but very poor knowledge of recommended alcohol-use limits (24%). Participants were willing to discuss alcohol use (88%) and to screen (71%) for alcohol-use disorders. Most health care practitioners report significant stigma against those with alcohol-use disorders (39% discrimination, 53% devaluation, 71% either). Counseling patients about high-risk alcohol use was directly and positively associated with at-risk alcohol and counseling education and believing it was common to ask patients about tobacco and alcohol use; it was negatively associated with believing it was 'not my role' or that knowing about alcohol use 'won't make a difference'. Stigma was negatively and indirectly associated with counseling patients. In conclusion, in an ED in Tanzania, health care practitioners have positive attitudes toward addressing at-risk alcohol use, and endorsed having training in alcohol misuse in school. Unfortunately, participants did not demonstrate knowledge of recommended alcohol limit guidelines. Similarly, among practitioners, there is a significant discrimination and devaluation stigma against those who misuse alcohol. These factors must be addressed prior to a successful implementation of an alcohol harm reduction intervention.

Assessment of animal hosts of pathogenic Leptospira in northern Tanzania.

Leptospirosis is a zoonotic bacterial disease that affects more than one million people worldwide each year. Human infection is acquired through direct or indirect contact with the urine of an infected animal. A wide range of animals including rodents and livestock may shed Leptospira bacteria and act as a source of infection for people. In the Kilimanjaro Region of northern Tanzania, leptospirosis is an important cause of acute febrile illness, yet relatively little is known about animal hosts of Leptospira infection in this area. The roles of rodents and ruminant livestock in the epidemiology of leptospirosis were evaluated through two linked studies. A cross-sectional study of peri-domestic rodents performed in two districts with a high reported incidence of human leptospirosis found no evidence of Leptospira infection among rodent species trapped in and around randomly selected households. In contrast, pathogenic Leptospira infection was detected in 7.08% cattle (n = 452 [5.1-9.8%]), 1.20% goats (n = 167 [0.3-4.3%]) and 1.12% sheep (n = 89 [0.1-60.0%]) sampled in local slaughterhouses. Four Leptospira genotypes were detected in livestock. Two distinct clades of L. borgpetersenii were identified in cattle as well as a clade of novel secY sequences that showed only 95% identity to known Leptospira sequences. Identical L. kirschneri sequences were obtained from qPCR-positive kidney samples from cattle, sheep and goats. These results indicate that ruminant livestock are important hosts of Leptospira in northern Tanzania. Infected livestock may act as a source of Leptospira infection for people. Additional work is needed to understand the role of livestock in the maintenance and transmission of Leptospira infection in this region and to examine linkages between human and livestock infections.

Sociocultural and health system factors associated with mortality among febrile inpatients in Tanzania: a prospective social biopsy cohort study.

INTRODUCTION: Communicable diseases are the leading causes of death in Tanzania despite the existence of effective treatment tools. We aimed to assess the sociocultural and health system factors associated with mortality from febrile illness in northern Tanzania. METHODS: We interviewed febrile inpatients to determine prevalence of barriers in seeking or receiving care and grouped these barriers using the Three Delays model (delays at home, in transport and at healthcare facilities). We assessed 6-week mortality and, after matching on age, gender and severity of illness, measured the association between delays and mortality using conditional logistic regression. RESULTS: We enrolled 475 children, of whom 18 (3.8%) died, and 260 adults, of whom 34 (13.0%) died. For children, home delays were not associated with mortality. Among adults, a delay in care-seeking due to not recognising severe symptoms was associated with mortality (OR: 3.01; 95% CI 1.24 to 7.32). For transport delays, taking >1 hour to reach a facility increased odds of death in children (OR: 3.27; 95% CI 1.11 to 9.66) and adults (OR: 3.03; 95% CI 1.32 to 6.99). For health system delays, each additional facility visited was associated with mortality for children (OR: 1.59; 95% CI 1.06 to 2.38) and adults (OR: 2.00; 95% CI 1.17 to 3.41), as was spending >4 days between the first facility visit and reaching tertiary care (OR: 4.39; 95% CI 1.49 to 12.93). CONCLUSION: Our findings suggest that delays at home, in transport and in accessing tertiary care are risk factors for mortality from febrile illness in northern Tanzania. Interventions that may reduce mortality include community education regarding severe symptoms, expanding transportation infrastructure and streamlining referrals to tertiary care for the sickest patients.
