Awareness, treatment, control of hypertension and utilization of health care services following screening in the North-central region of Burkina Faso

Introduction: in Africa, a non-urban area is affected by hypertension. But in Burkina Faso, no study on factors associated with awareness, treatment and control of hypertension has not yet been published. The objectives of this report are to: (i) identify the factors associated with awareness, treatment, and control of hypertension in the adult population of Kaya health and demographic surveillance system (Kaya HDSS) and (ii) estimate health care services utilization by participant newly screened as hypertensive. Methods: a screening survey for hypertension was conducted on 1481 adults in Kaya HDSS in late 2012. Hypertensive individuals provided information relating to "awareness", "treatment" and "control" of their hypertension. After approximately two months, unaware hypertensive individuals were interviewed to know whether they had sought treatment. Results: during the screening survey, 123 individuals (9.4%) were identified as having hypertension. Among them, 33 (26.8%, 95% CI: 18.9-34.8) were aware of their condition, 25 (75.8%, 95% CI: 60.3-91.2) of them were receiving medication. Among those receiving treatment, 15 (60.0%, 95% CI: 39.4-80.6) had their blood pressure controlled. Semi-urban residence, presence of chronic diseases and physical inactivity were significantly associated with awareness of hypertension. Seventy two of the 90 participants who were classified as unaware were interviewed two months later. Out of them, 37 individuals had consulted a health worker and 28 received a diagnosis of hypertension. Conclusion: awareness was low but treatment and control of those who knew they were hypertensive were relatively high. These results could be used to improve management of hypertension in Burkina Faso

Gaps and opportunities for the integrated delivery of mother-child care, postpartum family planning and nutrition services in Burkina Faso, Côte d'Ivoire and Niger

# Background Maternal and infant deaths can be prevented through integrated service delivery during pregnancy, postpartum, and early childhood. Our study analyses the gaps and opportunities associated with integrating maternal, newborn, and child health (MNCH) services with postpartum family planning (PPFP) and nutrition services at different points of contact in health facilities in a preintervention context in west Africa. # Methods We conducted a qualitative study from June to July 2018 in Burkina Faso, Côte d'Ivoire and Niger. The points of contact studied at the health facility level were the prenatal care, postpartum care and immunisation/growth monitoring services. Individual in-depth interviews were used to collect data from key informants (providers, community health workers and mother-child health programme managers). To measure the degree of service integration, we used the dimensions and indicators included in the Integra Initiative framework concerning four aspects of integration: physical (the availability of multiple services in the health facility), temporal (the availability of care more than one day per week), provider level, and functional (the receipt of integrated services by the client). # Results The findings of this study show that the integrated delivery of MNCH, PPFP, and nutrition services is configured in similar ways in Burkina Faso, Côte d'Ivoire and Niger and is insufficient at all points of contact. Physical integration is high. However, the study found important gaps in temporal, functional and provider-level integration. The main barriers to integrated service delivery are the shortage of providers, the lack of training in integrated service delivery, and insufficient service organisation. However, the availability of multiple services throughout the week, the multiple points of contact between the mother-child pair and the health system, and the multiple skills of providers represent opportunities for functional integration through the establishment of a formal referral system between the different care units with follow-up and feedback among service providers. # Conclusions The provision of training and the development of a well-organised referral system in different health facilities, taking into account the specific characteristics of each health facility (urban/rural, primary health facility/district hospital), can improve the delivery of integrated MNCH, PPFP, and nutrition care to the mother-child pair

Assessment of missed opportunities for vaccination (MOV) in Burkina Faso using the World Health Organization's revised MOV strategy: Findings and strategic considerations to improve routine childhood immunization coverage.

BACKGROUND: Despite the remarkable achievements of the Expanded Programme on Immunization (EPI) in Burkina Faso, numerous challenges remain, including missed opportunities for vaccination (MOV) which occur when people visit a health facility with at least one vaccine due according to the national immunization schedule, are free of contraindications, and leave without receiving all due vaccine doses. In 2016, we used the revised World Health Organization's (WHO) MOV strategy to assess the extent of and reasons for MOV in Burkina Faso. METHODS: We purposively selected 27 primary health facilities (PHFs) from the eight health districts with the highest absolute numbers of children who missed the first dose of measles-rubella (MR1) in 2015. We conducted exit interviews with caregivers of children aged 0-23 months, and requested health workers to complete a self-administered knowledge, attitudes and practices (KAP) questionnaire. RESULTS: A total of 489 caregivers were interviewed, of which 411 were eligible for inclusion in our analysis. Medical consultation (35%) and vaccination (24.5%) were the most frequent reasons for visiting PHFs. Among the 73% of children eligible for vaccination, 76% of vaccination opportunities were missed. Among eligible children, the percentage with MOV was significantly higher in those aged ≥12 months and also in those attending for a reason other than vaccination. A total of 248 health workers completed the KAP questionnaire. Of these, 70% (n = 168/239) considered their knowledge on immunization to be insufficient or outdated; 83% failed to correctly identify valid contraindications to vaccination. CONCLUSION: Addressing MOV offers the potential for substantial increases in vaccine coverage and equity, and ultimately reducing the burden of vaccine-preventable diseases (VPDs). This will require the implementation of a series of interventions aimed at improving community knowledge and practices, raising health workers' awareness, and fostering the integration of immunization with other health services

CoNIC Challenge: Pushing the Frontiers of Nuclear Detection, Segmentation, Classification and Counting

Nuclear detection, segmentation and morphometric profiling are essential in helping us further understand the relationship between histology and patient outcome. To drive innovation in this area, we setup a community-wide challenge using the largest available dataset of its kind to assess nuclear segmentation and cellular composition. Our challenge, named CoNIC, stimulated the development of reproducible algorithms for cellular recognition with real-time result inspection on public leaderboards. We conducted an extensive post-challenge analysis based on the top-performing models using 1,658 whole-slide images of colon tissue. With around 700 million detected nuclei per model, associated features were used for dysplasia grading and survival analysis, where we demonstrated that the challenge's improvement over the previous state-of-the-art led to significant boosts in downstream performance. Our findings also suggest that eosinophils and neutrophils play an important role in the tumour microevironment. We release challenge models and WSI-level results to foster the development of further methods for biomarker discovery

Impact of fee subsidy policy on perinatal health in a low-resource setting: A quasi-experimental study.

BACKGROUND:A national subsidy policy was introduced in 2007 in Burkina Faso to improve financial accessibility to facility-based delivery. In this article, we estimated the effects of reducing user fees on institutional delivery and neonatal mortality, immediately and three years after the introduction of the policy. METHODS:The study was based on a quasi-experimental design. We used data obtained from the 2010 Demographic and Health Survey, including survival information for 32,102 live-born infants born to 12,474 women. We used a multilevel Poisson regression model with robust variances to control for secular trends in outcomes between the period before the introduction of the policy (1 January, 2007) and the period after. In sensitivity analyses, we used two different models according to the different definitions of the period "before" and the period "after". RESULTS:Immediately following its introduction, the subsidy policy was associated with increases in institutional deliveries by 4% (RR = 1.04, 95% CI: 0.98-1.10) in urban areas and by 12% (RR = 1.12, 95% CI: 1.04-1.20) in rural areas. The results showed similar patterns in sensitivity analyses. This effect was particularly marked among rural clusters with low institutional delivery rates at baseline (RR = 1.44, 95% CI: 1.33-1.55). It was persistent for 42 months after the introduction of the policy but these increases were not statistically significant. At 42 months, the delivery rates had increased by 26% in rural areas (RR = 1.26; 95% CI: 0.86-1.86) and 13% (RR = 1.13; 95% CI: 0.88-1.46) in urban areas. There was no evidence of a significant decrease in neonatal mortality rates. CONCLUSION:The delivery subsidy implemented in Burkina Faso is associated with short-term increases in health facility deliveries. This policy has been particularly beneficial for rural households

Product quality as a lever to change farming practices to meet society’s expectations

Session 45 - Theatre 1International audienceProduct quality has long been the focus of taste improvement in livestock products. Today, new approaches induced by stakeholders aim to introduce new practices into specifications that meet society’s expectations. These changes may emerge at different levels of scale and initiative (private operators, groups of players or entire sector). Based on examples, we show how the evolution of specifications or new approaches meet expectations of society and how practices are being modified. The PDO-PGI labels increase the exigence about environmental issues and local feed use by animals. In milk sector, the cheese production now involves improving the sustainability of farming practices. A commercial approach with the BBC brand aims at modifying the animals’ diet to improve the nutritional aspect, mainly by increasing grass for ruminants, or using linseed for other animals. For poultry, the ‘European Chicken Commitment’ aims to improve welfare of conventional chicken production. This initiative focuses on several farming practices to improve animal welfare, and many operators have agreed to evolve them by 2026. In the rabbit sector, cooperatives and the largest French rabbit slaughterhouse has developed a new system for raising rabbits in large pens on the ground(‘Lapin et Bien’ brand). The aim was to take better account of animal welfare, and opposition with cage farming. In the beef sector, a new demand for red, tender and marbled meat is born especially in restaurants and butchers. To date, this type of meat is mainly imported. A wholesale butcher company has developed an integrated local chain with cattle farmers to adapt breeds, and practices to improve sustainability. These approaches are evaluated with criteria to asses sustainable livestock farming for tomorrow (feed-food competition, climate change mitigation, nutritionalintake and animal welfare). In addition to the co-construction of the technical system between the stakeholders, the approach is also based on shared governance, and a better price for the farmers

Out-of-pocket payments in the context of a free maternal health care policy in Burkina Faso: a national cross-sectional survey

Abstract Background In April 2016, Burkina Faso introduced a free health care policy for women. Instead of reimbursing health facilities, as many sub-Saharan countries do, the government paid them prospectively for covered services to avoid reimbursement delays, which are cited as a reason for the persistence of out-of-pocket (OOP) payments. This study aimed to (i) estimate the direct expenditures of deliveries and covered obstetric care, (ii) determine the OOP payments, and (iii) identify the patient and health facility characteristics associated with OOP payments. Methods A national cross-sectional study was conducted in September and October 2016 in 395 randomly selected health facilities. A structured questionnaire was administered to women (n = 593) who had delivered or received obstetric care on the day of the survey. The direct health expenditures included fees for consultations, prescriptions, paraclinical examinations, hospitalization and ambulance transport. A two-part model with robust variances was performed to identify the factors associated with OOP payments. Results A total of 587 women were included in the analysis. The median direct health expenses were US$5.38 [interquartile range (IQR):4.35–6.65], US$24.72 [IQR:16.57–46.09] and US$136.39 [IQR: 108.36–161.42] for normal delivery, dystocia and cesarean section, respectively. Nearly one-third (29.6$0.08 to US$98.67, with a median of US$1.77 [IQR:0.83–7.08]). Overall, 17.5% (n = 103) of the women had purchased drugs at private pharmacies, and 11.4% (n = 67) had purchased cleaning products for a room or equipment. OOP payments were more frequent with age, for emergency obstetric care and among women who work. The women’s health region of origin was also significantly associated with OOP payments. For those who made OOP payments, the amounts paid decreased with age but were higher in urban areas, in hospitals, and among the most educated women. The amounts paid were lower among students and were associated with health region. Conclusion The policy is effective for financial protection. However, improvements in the management and supply system of health facilities’ pharmacies could further reduce OOP payments in the context of the free health care policy in Burkina Faso

Presence of three dengue serotypes in Ouagadougou (Burkina Faso): research and public health implications

Abstract Background: The significant malaria burden in Africa has often eclipsed other febrile illnesses. Burkina Faso's first dengue epidemic occurred in 1925 and the most recent in 2013. Yet there is still very little known about dengue prevalence, its vector proliferation, and its poverty and equity impacts. Methods: An exploratory cross-sectional survey was performed from December 2013 to January 2014. Six primary healthcare centers in Ouagadougou were selected based on previously reported presence of Flavivirus. All patients consulting with fever or having had fever within the previous week and with a negative rapid diagnostic test (RDT) for malaria were invited to participate. Sociodemographic data, healthcare use and expenses, mobility, health-related status, and vector control practices were captured using a questionnaire. Blood samples of every eligible subject were obtained through finger pricks during the survey for dengue RDT using SD BIOLINE Dengue Duo (NS1Ag and IgG/IgM)® and to obtain blood spots for reverse transcription polymerase chain reaction (RT-PCR) analysis. In a sample of randomly selected yards and those of patients, potential Aedes breeding sites were found and described. Larvae were collected and brought to the laboratory to monitor the emergence of adults and identify the species
