Coût de la prise en charge des pathologies cardio-vasculaires au Burkina Faso.

INTRODUCTION: The management of cardiovascular pathologies has a high cost for users. PURPOSE OF THE RESEARCH: It is therefore important to assess the costs of hospitalization to gain a better understanding of its impact on care. RESULTS: This was a case series-type, descriptive, observational study with prospective data collection. RESULTS: A total of 103 patients were included, with a mean age of 51 years and extremes ranging from 14 to 86 years. The average length of stay was 7.1 days. Heart failure was the most frequent pathology (61.7%). The average monthly income per patient was 101,360 CFA francs. The average total direct cost during hospitalization was 114,015 CFAF. The average direct cost of drugs and consumables was 60,553.77 CFAF. The average direct cost of paraclinical examinations was 34,360.29 CFAF. Hospitalization costs averaged 16,747.47 CFAF. Total direct costs during hospitalization were 11,737,060 CFAF, dominated by drugs and medical consumables (53.14%), followed by complementary examinations (29.86%) and non-medical expenses (17%). During the study, 13.59% of patients were discharged against medical advice. Expenses were covered by the parents in 71.84% of cases. CONCLUSIONS: The average direct cost of hospitalization is well above the purchasing power of the majority of patients.

Évaluation de l'offre de soins en situation d'urgence basée sur la mise en place des postes de santé avancés dans la ville de Djibo, Burkina Faso, avril 2022.

INTRODUCTION: The town of Djibo in Burkina Faso has been facing a security and humanitarian crisis since 2015. The internally displaced populations who have taken refuge there have several needs, including health care. The establishment of advanced health posts is part of the health-nutrition service delivery strategy adopted to address these needs. We evaluated the contribution of these advanced health posts in terms of availability, access to care, and beneficiary satisfaction. METHODOLOGY: We conducted a mixed descriptive and analytical cross-sectional study from May 1, 2021 to January 30, 2022 on the host population, internally displaced people, health workers, and selected health facilities in Djibo. It involved 422 people for the quantitative component. The quantitative data, including those from 2016 to 2020, were analyzed using Epi Info software, version 7.2.3.1, and completed by a qualitative component. RESULTS: Of the nine peripheral structures studied, seven were advanced health posts offering basic care such as prenatal and postnatal consultations, infant monitoring, and vaccination. Nutritional interventions were inadequate in some of these advanced health posts. Geographic access was satisfactory, but financial access was not. CONCLUSION: The strategy made it possible to meet basic health care needs in this crisis context, but financial access must be improved.

[Complications of female genital mutilation: epidemiology and management of cases at Ouahigouya regional teaching hospital, Burkina Faso]. / Complications des mutilations génitales féminines : épidémiologie et prise en charge des cas au Centre hospitalier universitaire (CHU) régional de Ouahigouya, Burkina Faso.

Background: Female genital mutilation is still common in Burkina Faso, despite decades of struggle against its practice. The northern region of this country has one of the highest prevalence of this practice at the national level with 76% of women mutilated. The objective of our study was to describe the health complications of female genital mutilation treated in the referral hospital in this region. Patients and methods: This was a descriptive cross-sectional study with retrospective data collection over a 13-year period, from September 15, 2009 to September 14, 2022. Patients admitted for genital or loco-regional complications related to genital mutilation were included. Mutilated parturients without infibulation, victims of vulvar tears or who had undergone episiotomy were not included. Results: We recorded 204 patients, representing 3,1% of consultants, and an annual frequency of 15.7 cases. The ages of the victims ranged from 15 months to 31 years. The 15-20 age group was the most represented (49.3%). Victims were more likely to come from urban than rural areas. The main reasons for consultation were vulvar stricture, dyspareunia, impossibility of sexual intercourse, and dysuria. These were medium- and long-term complications of the mutilation. These complications were related to infibulation in 81.8% of cases and to type II mutilation in 18.2%. Surgery accounted for 89.9% of treatments, with drug treatments alone accounting for 10.1%. Deinfibulation was the most common surgical procedure. No clitoral reconstruction was performed. The outcome was favourable in all cases. Conclusion: There are many local and regional complications of genital mutilation, but fortunately their treatment has a good anatomical prognosis. However, psychological complications remain to be evaluated and managed in our context. The management of these complications should be an opportunity to raise awareness among the patients' family circles to abandon the practice.

Form and functioning: contextualising the start of the global financing facility policy processes in Burkina Faso.

BACKGROUND: Burkina Faso joined the Global Financing Facility for Women, Children and Adolescents (GFF) in 2017 to address persistent gaps in funding for reproductive, maternal, newborn, child, and adolescent health and nutrition (RMNCAH-N). Few empirical papers deal with how global funding mechanisms, and specifically GFF, support resource mobilisation for health nationally. OBJECTIVE: This study describes the policy processes of developing the GFF planning documents (the Investment Case and Project Appraisal Document) in Burkina Faso. METHODS: We conducted an exploratory qualitative policy analysis. Data collection included document review (N = 74) and in-depth semi-structured interviews (N = 23). Data were analysed based on the components of the health policy triangle. RESULTS: There was strong national political support to RMNCAH-N interventions, and the process of drawing up the investment case (IC) and the project appraisal document was inclusive and multi-sectoral. Despite high-level policy commitments, subsequent implementation of the World Bank project, including the GFF contribution, was perceived by respondents as challenging, even after the project restructuring process occurred. These challenges were due to ongoing policy fragmentation for RMNCAH-N, navigation of differing procedures and perspectives between stakeholders in the setting up of the work, overcoming misunderstandings about the nature of the GFF, and weak institutional anchoring of the IC. Insecurity and political instability also contributed to observed delays and difficulties in implementing the commitments agreed upon. To tackle these issues, transformational and distributive leaderships should be promoted and made effective. CONCLUSIONS: Few studies have examined national policy processes linked to the GFF or other global health initiatives. This kind of research is needed to better understand the range of challenges in aligning donor and national priorities encountered across diverse health systems contexts. This study may stimulate others to ensure that the GFF and other global health initiatives respond to local needs and policy environments for better implementation.

Main findings: There was a high level of political commitment to the Global Financing Facility in Burkina Faso, but its implementation has been hindered by policy fragmentation, competing interests, weak institutional anchoring, and misunderstandings.Added knowledge: This study documents the initiation of a global health initiative, specifically the Global Financing Facility, including the development and implementation of its planning documents, namely the Investment Case and Project Appraisal Document.Global health impact for policy and action: An understanding of the factors that facilitated or impeded the policy processes of developing and implementing the Global Financing Facility can inform the design and implementation of future initiatives.

Mobilizing stakeholders for implant removals in Burkina Faso using landscape assessment data.

BACKGROUND: Successful efforts to encourage uptake of subdermal contraceptive implants, with a lifespan of three to five years, necessitate planning to ensure that quality removal services are available when desired. In Burkina Faso, implant use has tripled over the past 8 years and now comprises almost half of the contraceptive method mix. Population Monitoring for Action (PMA) surveys identified barriers to obtaining quality removal when desired, particularly when the implant is not palpable, or providers lack needed skills or supplies. The Expanding Family Planning Choices (EFPC) project supported ministries of health in four countries with evaluation and strengthening of implant removal services. METHODS: An implant removal landscape assessment was conducted at 24 health facilities in three regions of Burkina Faso with high implant use that included provider observations of implant removal, interviews with providers and health facility managers, and facility readiness surveys. The project used landscape data to mobilize stakeholders through a series of participatory workshops to develop a collaborative roadmap and commit to actions supporting quality implant removals. RESULTS: Landscape findings revealed key gaps in provision of quality removal services, including high levels of provider confidence for implant insertion and removal (82% and 71%, respectively), low competence performing simple and difficult removals (19.2% and 11.1%, respectively), inadequate supplies and equipment (no facilities had all necessary materials for removal), lack of difficult removal management systems, and a lack of standard data collection tools for removal. Exposure to the data convinced stakeholders to focus on removals rather than expanding insertion services. While not all roadmap commitments were achieved, the process led to critical investments in quality implant removals. CONCLUSION: Landscape data revealed that facilities lack needed supplies and equipment, and providers lack skills needed to perform quality implant removals, limiting client reproductive choice. Disseminating this data enabled stakeholders to identify and commit to evidence-based priority actions. Stakeholders have since capitalized on program learnings and the roadmap, including following MOH guidance for implant removal supplies and health provider training. Our experience in Burkina Faso offers a replicable model of how data can direct collective action to improve quality of contraceptive implant removals.

Pulmonary function assessment among conventional and organic cotton farmers exposed to pesticides in the Central-West region of Burkina Faso.

BACKGROUND: Respiratory diseases have been associated with the exposure of populations to some environmental pollutants such as pesticides. To assess effects of pesticides on farmers' respiratory health, this study aimed to evaluate the pulmonary function of cotton farmers exposed to synthetic and natural pesticides in the Central-West region of Burkina Faso. METHODS: A cross-sectional study was conducted from June to July 2022 among 281 conventional and 189 organic cotton farmers. After collecting information on pesticide use conditions, pulmonary function tests (PFTs) were performed on each farmer according to the American Thoracic Society/European Respiratory Society guidelines, in order to assess chronic respiratory effects among cotton producers. Binary logistic regression was used to assess factors associated with the occurrence of ventilatory changes. RESULTS: Both conventional and organic cotton farmers reported similar chronic respiratory symptoms in different proportions. The main reported were rhinitis (54.45% conventional vs. 34.92% organic), chest pains (41.28% conventional vs. 23.81% organic), cough (33.45% conventional, 24.34% organic), breathlessness (31.67% conventional, 4.23% organic) (p<0.05). 16.18% and 27.50% of conventional male and female cotton farmers, respectively, had a restrictive defect. Among organic cotton farmers, 15.85% and 18.69%, respectively, of males and females had a restrictive defect. Furthermore, a significant increase in the predicted average percentage of FEV1/FVC ratio was observed among organic cotton farmers after salbutamol's use (p = 0.039). The type of cultivated cotton was not associated with ventilatory changes neither in the univariate analysis, nor in the multivariate analysis. Other factors such as farmers' age, BMI and insecticides use frequency per year were also important. Farmers who used insecticides more than 6 times per season had an increased risk of developing an obstructive defect (OR = 1.603; 95%CI: 0.484-5.309) compared to those who used them 6 times or less. CONCLUSION: Chronic respiratory signs and ventilatory impairments were found among conventional and, to our knowledge, for the first time among organic cotton producers. However, these health effects were more prevalent among conventional cotton farmers than organic ones.

Cost-Effectiveness of Test-and-Treat Strategies to Reduce the Antibiotic Prescription Rate for Acute Febrile Illness in Primary Healthcare Clinics in Africa.

BACKGROUND: Inappropriate antibiotic use increases selective pressure, contributing to antimicrobial resistance. Point-of-care rapid diagnostic tests (RDTs) would be instrumental to better target antibiotic prescriptions, but widespread implementation of diagnostics for improved management of febrile illnesses is limited. OBJECTIVE: Our study aims to contribute to evidence-based guidance to inform policymakers on investment decisions regarding interventions that foster more appropriate antibiotic prescriptions, as well as to address the evidence gap on the potential clinical and economic impact of RDTs on antibiotic prescription. METHODS: A country-based cost-effectiveness model was developed for Burkina Faso, Ghana and Uganda. The decision tree model simulated seven test strategies for patients with febrile illness to assess the effect of different RDT combinations on antibiotic prescription rate (APR), costs and clinical outcomes. The incremental cost-effectiveness ratio (ICER) was expressed as the incremental cost per percentage point (ppt) reduction in APR. RESULTS: For Burkina Faso and Uganda, testing all patients with a malaria RDT was dominant compared to standard-of-care (SoC) (which included malaria testing). Expanding the test panel with a C-reactive protein (CRP) test resulted in an ICER of $ 0.03 and $ 0.08 per ppt reduction in APR for Burkina Faso and Uganda, respectively. For Ghana, the pairwise comparison with SoC-including malaria and complete blood count testing-indicates that both testing with malaria RDT only and malaria RDT + CRP are dominant. CONCLUSION: The use of RDTs for patients with febrile illness could effectively reduce APR at minimal additional costs, provided diagnostic algorithms are adhered to. Complementing SoC with CRP testing may increase clinicians' confidence in prescribing decisions and is a favourable strategy.

Reconciling devolution with health financing and public financial management: challenges and policy options for the health sector.

The interplay between devolution, health financing and public financial management processes in health-or the lack of coherence between them-can have profound implications for a country's progress towards universal health coverage. This paper explores this relationship in seven Asian and African countries (Burkina Faso, Kenya, Mozambique, Nigeria, Uganda, Indonesia and the Philippines), highlighting challenges and suggesting policy solutions. First, subnational governments rely heavily on transfers from central governments, and most are not required to allocate a minimum share of their budget to health. Central governments channelling more funds to subnational governments through conditional grants is a promising way to increase public financing for health. Second, devolution makes it difficult to pool funding across populations by fragmenting them geographically. Greater fiscal equalisation through improved revenue sharing arrangements and, where applicable, using budgetary funds to subsidise the poor in government-financed health insurance schemes could bridge the gap. Third, weak budget planning across levels could be improved by aligning budget structures, building subnational budgeting capacity and strengthening coordination across levels. Fourth, delays in central transfers and complicated procedures for approvals and disbursements stymie expenditure management at subnational levels. Simplifying processes and enhancing visibility over funding flows, including through digitalised information systems, promise to improve expenditure management and oversight in health. Fifth, subnational governments purchase services primarily through line-item budgets. Shifting to practices that link financial allocations with population health needs and facility performance, combined with reforms to grant commensurate autonomy to facilities, has the potential to enable more strategic purchasing.

Cost-effectiveness of a radio intervention to stimulate early childhood development: protocol for an economic evaluation of the SUNRISE trial in Burkina Faso.

INTRODUCTION: Approximately 250 million children under 5 years of age are at risk of poor development in low-income and middle-income countries. However, existing early childhood development (ECD) interventions can be expensive, labour intensive and challenging to deliver at scale. Mass media may offer an alternative approach to ECD intervention. This protocol describes the planned economic evaluation of a cluster-randomised controlled trial of a radio campaign promoting responsive caregiving and opportunities for early learning during the first 3 years of life in rural Burkina Faso (SUNRISE trial). METHODS AND ANALYSIS: The economic evaluation of the SUNRISE trial will be conducted as a within-trial analysis from the provider's perspective. Incremental costs and health outcomes of the radio campaign will be compared with standard broadcasting (ie, 'do nothing' comparator). All costs associated with creating and broadcasting the radio campaign during intervention start-up and implementation will be captured. The cost per child under 3 years old reached by the intervention will be calculated. Incremental cost-effectiveness ratios will be calculated for the trial's primary outcome (ie, incremental cost per SD of cognitive gain). A cost-consequence analysis will also be presented, whereby all relevant costs and outcomes are tabulated. Finally, an analysis will be conducted to assess the equity impact of the intervention. ETHICS AND DISSEMINATION: The SUNRISE trial has ethical approval from the ethics committees of the Ministry of Health, Burkina Faso, University College London and the London School of Hygiene and Tropical Medicine. The results of the economic evaluation will be disseminated in a peer-reviewed journal and presented at a relevant international conference. TRIAL REGISTRATION NUMBER: The SUNRISE trial was registered with ClinicalTrials.gov on 19 April 2019 (identifier: NCT05335395).

The Cost and Cost-Effectiveness of an Integrated Wasting Prevention and Screening Intervention Package in Burkina Faso and Mali.

BACKGROUND: Little is known about costs and cost effectiveness of interventions that integrate wasting prevention into screening for child wasting. OBJECTIVES: This study's objective was to estimate the cost and cost-effectiveness of an intervention that integrated behavior change communication (BCC) and small-quantity lipid-based nutrient supplements (SQ-LNS) into platforms for wasting screening in Burkina Faso (a facility-based platform, where BCC was enhanced compared with standard care) and Mali (a community-based platform, with standard BCC). METHODS: Activity-based costing was used to estimate the cost per child-contact for the intervention and the comparison group, which did not receive the intervention. Costs were ascertained from accounting records, interviews, surveys, and observations. The number of child-contacts was calculated using population size estimates and average attendance rates for each service. Costs per disability-adjusted life year (DALY) averted were estimated using a Markov model populated with data from the parent trials on impact of wasting incidence and treatment coverage. RESULTS: In the intervention group in Burkina Faso, the cost per child-contact of facility-based screening was $0.85 of enhanced BCC was $4.28, and of SQ-LNS was $8.86. In Mali, the cost per child-contact of community-based screening was $0.57, standard BCC was $0.72, and SQ-LNS was $4.14. Although no SQ-LNS costs were incurred in the comparison groups (hence lower total costs), costs per child-contact for screening and BCC were higher because coverage of these services was lower. The intervention package cost $1073 per DALY averted in Burkina Faso and $747 in Mali. CONCLUSIONS: Integration of wasting prevention into screening for child wasting led to higher total costs but lower unit costs than standard screening due to increased coverage. Greater cost-effectiveness could be achieved if BCC were strengthened and led to improved caregiver health and nutrition practices and if screening triggered appropriate use of services and higher treatment coverage.

Costs of integrating hepatitis B screening and antiviral prophylaxis into routine antenatal care in Burkina Faso: Treat all versus targeted strategies.

OBJECTIVE: Economic feasibility of eliminating mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in highly endemic African countries remains uncertain. Prevention of MTCT (PMTCT) involves screening pregnant women for hepatitis B surface antigen (HBsAg), identifying those with high viral loads or hepatitis B e antigen (HBeAg), and administering tenofovir prophylaxis to high-risk women. We estimated the costs of integrating PMTCT services into antenatal care in Burkina Faso, based on four different strategies to select women for tenofovir prophylaxis: (1) HBV DNA (≥200 000 IU/mL), (2) HBeAg, (3) hepatitis B core-related antigen rapid diagnostic test (HBcrAg-RDT) and (4) all HBsAg-positive women. METHODS: Using a micro-costing approach, we estimated the incremental economic cost of integrating each strategy into routine antenatal care in 2024, compared to neonatal vaccination alone. Sensitivity analyses explored variations in prevalence, service coverage, test and tenofovir prices. RESULTS: HBcrAg-RDT strategy was the least expensive, with a total economic cost of US$3959689, compared to HBV DNA (US$6128875), HBeAg (US$4135233), and treat-all (US$4141206). The cost per pregnant woman receiving tenofovir prophylaxis varied from US$61.88 (Treat-all) to US$1071.05 (HBV DNA). The Treat-All strategy had the lowest marginal cost due to a higher number of women on tenofovir (66928) compared to HBV DNA (5722), HBeAg (10020), and HBcrAg-RDT (7234). In sensitivity analyses, the treat-all strategy became less expensive when the tenofovir price decreased. CONCLUSION: HBcrAg-RDT minimizes resource use and costs, representing 0.61% of Burkina Faso's 2022 health budget. This study highlights the potential economic feasibility of these strategies and provides valuable resources for conducting cost-effectiveness analyses.

Characterizing provider bias in contraceptive care in Tanzania and Burkina Faso: A mixed-methods study.

Provider bias based on age, marital status, and parity may be a barrier to quality contraceptive care. However, the extent to which bias leads to disparities in care quality is not well understood. In this mixed-methods study, we used four different data sources from the same facilities to assess the extent of bias and how much it affects contraceptive care. First, we surveyed providers in Tanzania and Burkina Faso (N = 295) to assess provider attitudes about young, unmarried, and nulliparous clients. Second, mystery clients anonymously visited providers for contraceptive care and we randomly assigned the reported age, marital status, and parity of each visit (N = 306). We used data from these visits to investigate contraceptive care disparities across 3 domains: information provision and counseling quality, contraceptive method provision, and perceived treatment. Third, we complemented mystery client data with client exit surveys (N = 31,023) and client in-depth interviews (N = 36). In surveys, providers reported biased attitudes against young, unmarried, and nulliparous clients seeking contraceptives. Similarly, we found disparities according to these characteristics in the reporting of contraceptive care quality; however, we found that each characteristic affected a different quality of care domain. Among mystery clients we found age-related disparities in the provision of methods; 16/17-year-old clients were 18 and 11 percentage points less likely to perceive they could take a contraceptive method relative to 24-year-old clients in Tanzania and Burkina Faso, respectively. Unmarried mystery clients perceived worse treatment from providers compared to married clients. Nulliparous mystery clients reported lower quality contraceptive counseling than their parous counterparts. These results suggest that clients of different characteristics likely experience bias across different elements of care. Improving care quality and reducing disparities will require attention to which elements of care are deficient for different types of clients.

Market assessment of fortified parboiled rice in Burkina Faso.

Micronutrient deficiency remains a daunting issue in many parts of the world. Effective interventions are needed to deal with the problem, which should consider production and consumption traditions and trends to improve their success. Parboil rice is a growing staple in Burkina Faso, where micronutrient deficiency remains high. This paper assesses the market feasibility of fortified rice through parboiling using a limited-water soaking method. Our findings suggest that consumers are willing to pay a premium for fortified rice versus conventional parboiled rice after they are informed about the importance of the problem and the potential benefits of fortified rice. A stylized cost analysis also reveals that the cost of producing fortified rice using a limited-water soaking method could exceed the premiums consumers are willing to pay, and therefore that public intervention may be needed to improve the odds of adoption by consumers. The findings have implication beyond Burkina Faso, and could guide market development in other regions where production and consumption of parboiled rice is well established.

Assessment of Culicidae collection methods for xenomonitoring lymphatic filariasis in malaria co-infection context in Burkina Faso.

BACKGROUND: Entomological surveillance of lymphatic filariasis and malaria infections play an important role in the decision-making of national programs to control, or eliminate these both diseases. In areas where both diseases prevalence is low, a large number of mosquitoes need to be sampled to determine vectors infection rate. To do this, efficient mosquito collection methods must be used. This study is part in this framework, to assess appropriate mosquito collection methods for lymphatic filariasis xenomonitoring in a coexistence context with malaria in Burkina Faso. METHODOLOGY/PRINCIPAL FINDINGS: Mosquito collections were performed between August and September 2018 in four villages (Koulpissi, Seiga, and Péribgan, Saptan), distributed in East and South-West health regions of Burkina Faso. Different collection methods were used: Human Landing Catches (HLC) executed indoor and outdoor, Window Exit-Trap, Double Net Trap (DNT) and Pyrethrum Spray Catches (PSC). Molecular analyses were performed to identify Anopheles gambiae s.l. sibling species and to detect Wuchereria bancrofti and Plasmodium falciparum infection in Anopheles mosquitoes. A total of 3 322 mosquitoes were collected among this, Anopheles gambiae s.l. was the vector caught in largest proportion (63.82%). An. gambiae s.l. sibling species molecular characterization showed that An. gambiae was the dominant specie in all villages. The Human Landing Catches (indoor and outdoor) collected the highest proportion of mosquitoes (between 61.5% and 82.79%). For the sampling vectors infected to W. bancrofti or P. falciparum, PSC, HLC and Window Exit-Trap were found the most effective collection methods. CONCLUSIONS/SIGNIFICANCE: This study revealed that HLC indoor and outdoor remained the most effective collection method. Likewise, the results showed the probability to use Window Exit-Trap and PSC collection methods to sample Anopheles infected.

Effects of the COVID-19 Pandemic on ART Initiation and Access to HIV Viral Load Monitoring in Adults Living With HIV in West Africa: A Regression Discontinuity Analysis.

OBJECTIVES: Efforts to control the COVID-19 pandemic have potentially compromised the availability and/or quality of HIV services. We aimed to assess the pandemic's impact on antiretroviral therapy (ART) initiation and HIV viral load (VL) monitoring in 3 West African countries. METHODS: We used routinely collected data from 5 clinics contributing to the International epidemiologic Database to Evaluate AIDS collaboration in Burkina Faso, Côte d'Ivoire, and Nigeria. We included ART-naïve adults living with HIV initiating ART from January 1, 2018. We conducted regression discontinuity analysis to estimate changes in the number of ART initiations and VL measures per week, before and during the pandemic period in each country. RESULTS: In clinics in Burkina Faso and Côte d'Ivoire, ART initiations per week remained constant throughout the studied periods (-0.24 points (p) of ART initiations/week 95% CI: -5.5 to 5.9, -0.9 p, 95% CI: -8.5 to 8.6, respectively), whereas in Nigeria's clinic, they decreased significantly (-6.3 p, 95% CI: -10.8 to -1.7) after the beginning of the pandemic. The volume of VL tests performed decreased significantly in all 3 countries (-17.0 p, 95% CI: -25.3 to -8.6 in Burkina Faso, -118.4 p, 95% CI: -171.1 to -65.8 in Côte d'Ivoire and -169.1 p, 95% CI: -282.6 to -55.6 in Nigeria). CONCLUSIONS: HIV clinics in two out of three countries in West Africa demonstrated resilience as they successfully maintained access to ART for ALWH despite the challenges imposed by the pandemic. However, VL monitoring was severely disrupted and did not return to prepandemic levels approximately 1 year after the beginning of the pandemic. Continued monitoring of the HIV care continuum in the postpandemic period is essential to mitigate potential enduring effects on ALWH's virological and clinical outcomes.

Quantitative assessment of food safety interventions for Campylobacter spp. and Salmonella spp. along the chicken meat supply chain in Burkina Faso and Ethiopia.

Rural and small-scale chicken farming is a major source of income in most African countries, and chicken meat is an important source of nutrients. However, chicken meat can be contaminated with Campylobacter spp. and Salmonella spp., pathogens with a high reported burden of foodborne illnesses. Therefore, it is essential to control these pathogens in chicken meat. Quantitative microbial risk assessments (QMRA) can aid the development of effective food safety control measures and are currently lacking in chicken meat supply chains in the African context. In this study, we developed stochastic QMRA models for Salmonella spp. and Campylobacter spp. in the chicken meat supply chain in Burkina Faso and Ethiopia employing the modular process risk model in @Risk software. The study scope covered chicken farming, transport, slaughtering, consumer handling, and consumption. Effectiveness of candidate interventions was assessed against baseline models' outputs, which showed that the mean annual Campylobacter spp. risk estimates were 6482 cases of illness per 100,000 persons and 164 disability adjusted life years (DALYs) per 100,000 persons in Burkina Faso, and 12,145 cases and 272 DALYs per 100,000 persons in Ethiopia. For Salmonella spp., mean annual estimates were 2713 cases and 1212 DALYs per 100,000 persons in Burkina Faso, and 4745 cases and 432 DALYs per 100,000 persons in Ethiopia. Combining interventions (improved hand washing plus designated kitchen utensils plus improved cooking) resulted in 75 % risk reduction in Burkina Faso at restaurants and 93 to 94 % in Ethiopia at homes for both Salmonella spp. and Campylobacter spp. For Burkina Faso, adding good hygienic slaughter practices at the market to these combined interventions led to over 91 % microbial risk reduction. Interventions that involved multiple food safety actions in a particular step of the supply chain or combining different interventions from different steps of the supply chain resulted in more risk reduction than individual action interventions. Overall, this study demonstrates how diverse and scanty food supply chain information can be applied in QMRA to provide estimates that can be used to stimulate risk-based food safety action in African countries.

Chapitre 4. Subventions discriminatoires de soins medicaux à l'épreuve du principe éthique de la justice : cas d'un service d'orl au burkina faso.

INTRODUCTION: A legal exception to the principle of equal health rights, discriminatory subsidies often pose an ethical dilemma in the field of application. AIM: To analyze discriminatory subsidies for healthcare in the light of the ethical principle of justice and to propose alternatives to any inherent legal and ethical conflicts. METHOD: This was a qualitative, descriptive and analytical study based on semi-structured interviews with caregivers. RESULTS: Participants felt that the application of discriminatory subsidies has a negative impact on substantial distributive justice. The infringements of the award conditions were exclusively for the benefit of the patients concerned. Their impact was considered positive on distributive justice and negative on formal justice. DISCUSSION: Discriminatory care subsidies generally stem from a legal requirement whose application should not be ambiguous. It is apparent that the infringements of the conditions for attribution were in favour of substantial distributive justice. This opposition is a potential source of decision-making difficulties for caregivers who often choose to violate conditions for the benefit of their indigent patients. There are therefore violations of ethically understandable standards, which must be admitted. This could be done through the provision of exceptions for the application of standards for ”noble causes” and conscientious objection clauses in health policy texts. CONCLUSION: The legitimacy of health policy norms is essential for their effective application, hence the interest of taking distributive justice into account in the genesis of formal norms.

The public health impact and cost-effectiveness of the R21/Matrix-M malaria vaccine: a mathematical modelling study.

BACKGROUND: The R21/Matrix-M vaccine has demonstrated high efficacy against Plasmodium falciparum clinical malaria in children in sub-Saharan Africa. Using trial data, we aimed to estimate the public health impact and cost-effectiveness of vaccine introduction across sub-Saharan Africa. METHODS: We fitted a semi-mechanistic model of the relationship between anti-circumsporozoite protein antibody titres and vaccine efficacy to data from 3 years of follow-up in the phase 2b trial of R21/Matrix-M in Nanoro, Burkina Faso. We validated the model by comparing predicted vaccine efficacy to that observed over 12-18 months in the phase 3 trial. Integrating this framework within a mathematical transmission model, we estimated the cases, malaria deaths, and disability-adjusted life-years (DALYs) averted and cost-effectiveness over a 15-year time horizon across a range of transmission settings in sub-Saharan Africa. Cost-effectiveness was estimated incorporating the cost of vaccine introduction (dose, consumables, and delivery) relative to existing interventions at baseline. We report estimates at a median of 20% parasite prevalence in children aged 2-10 years (PfPR2-10) and ranges from 3% to 65% PfPR2-10. FINDINGS: Anti-circumsporozoite protein antibody titres were found to satisfy the criteria for a surrogate of protection for vaccine efficacy against clinical malaria. Age-based implementation of a four-dose regimen of R21/Matrix-M vaccine was estimated to avert 181 825 (range 38 815-333 491) clinical cases per 100 000 fully vaccinated children in perennial settings and 202 017 (29 868-405 702) clinical cases per 100 000 fully vaccinated children in seasonal settings. Similar estimates were obtained for seasonal or hybrid implementation. Under an assumed vaccine dose price of US$3, the incremental cost per clinical case averted was $7 (range 4-48) in perennial settings and $6 (3-63) in seasonal settings and the incremental cost per DALY averted was $34 (29-139) in perennial settings and $30 (22-172) in seasonal settings, with lower cost-effectiveness ratios in settings with higher PfPR2-10. INTERPRETATION: Introduction of the R21/Matrix-M malaria vaccine could have a substantial public health benefit across sub-Saharan Africa.

A mixed methods evaluation of the effectiveness of an oral health training program for disability care workers in Burkina Faso.

BACKGROUND: While efforts to improve the oral health of vulnerable populations have received little attention in general, the situation of children with disabilities in low- income countries (LICs) remains especially challenging. The present study evaluated the effectiveness of an oral health training provided to disability care workers in Ouagadougou, Burkina Faso thereby contributing to closing the knowledge gap in disability research in relation to oral health in LICs. METHODS: This was a single-arm pre-post study following an embedded mixed methods design using the New World Kirkpatrick training effectiveness evaluation model. For the purposes of this study, three levels of the Kirkpatrick (KP) evaluation were considered: reaction, learning and behaviour. RESULTS: A total of 44 care workers from 6 disability centres participated in the study. Care worker post-training scores (Md = 17) were significantly higher compared to pre-training scores (Md = 13) [Wilcoxon signed-ranks test: Z= -5.53, p < .001, r = .59.] The median value for care worker confidence in applying training material in their everyday job was 7 out of 10 points (IQR = 3). At the 1-month training follow-up, 3 centres had implemented daily toothbrushing for people with disabilities. CONCLUSION: These findings suggest that tailored training led to an increase in care worker confidence and motivation to implement oral health activities, in knowledge about oral health and a partial implementation uptake of daily toothbrushing in disability centres. Further long-term evaluations with dental care provision in rural and urban settings are needed to lower the high oral disease burden of people with disabilities in Burkina Faso.

Nutritional quality of the traditionally cooked Zamnè, a wild legume and a delicacy in Burkina Faso: assessment of the process effectiveness and the properties of cooking alkalis.

Zamnè is a wild legume and a famine food that attracts interest for its health benefits and has become a delicacy in Burkina Faso. This study aimed to determine the nutritional quality of the traditionally cooked Zamnè, appreciate the effectiveness of the traditional cooking process, and compare the properties of the traditionally used cooking alkalis (i.e., potash or plant ash leachate and sodium bicarbonate). Yet, as shown, the traditional cooking of Zamnè is a very aggressive process that results in high disintegration of cell walls and membranes and leaching of most water-soluble constituents and nutrients (i.e., free amino acids, soluble nitrogen, sugars, soluble dietary fibers, and soluble phenolics). In addition, the extensive boiling and the cooking alkalis induced the sequestration of calcium, iron, magnesium, and zinc, significantly impairing their bioaccessibility. Despite the difference in the modus operandi of the cooking alkalis, there was no significant difference in the cooking outcomes. The traditionally cooked Zamnè presented high dietary protein (4.8 g), lipid (3.3 g), fiber (6.7-7.7 g), and metabolizable energy (63-65 kcal) contents (per 100 g fresh weight). Most antinutritional factors (i.e., non-protein nitrogen, tannins, and trypsin inhibitors) were eliminated. The proteins were relatively well preserved despite the aggressive alkaline processing. They demonstrated an appreciable digestibility (75%) and predicted PER (1.5) and a fairly balanced essential amino acid composition - which should completely meet the requirements for adults. The lipid content and composition were also well preserved and contained predominantly linoleic (C18:2n-6), oleic (C18:1c9), stearic (C18:0), and palmitic (C16:0) acids (33, 34, 10, and 15% total fatty acids, respectively). Overall, though extensive alkaline cooking seems a straightforward option to overcome the hard-to-cook problem of Zamnè, processing alternatives might be useful to reduce nutrient losses, improve the digestibility of the final product, and capture its full nutritional value.
