Promoting the use of evidence in health policy-making in the economic commission of the West African States Region: Exploring the perception of policy-makers on the necessity of an evidence-based policy-making guidance.

Background: The West African Health Organization (WAHO) is promoting the use of evidence in policy-making within West Africa. The need for increased understanding of the complexities of the evidence-to-policy process among policy-makers in West Africa necessitates the development of evidence-based policy-making (EBPM) guidance. The purpose of this study was to interact with policy-makers from West African countries to identify the necessity of EBPM guidance for the subregion. Methods: A cross-sectional qualitative study design was used to elicit the views/opinions of senior health policy-makers from across the 15 West African countries on why an EBPM Guidance is necessary for the subregion. The policy-makers were engaged during WAHO-organized regional evidence-to-policy meetings on the improvement of maternal and child health outcomes held in Senegal in 2019. Face-to-face, one-on-one interactions, interviews, and deliberations during the meeting plenary sessions were held with the policy-makers, who participated in the regional meeting. Results: Up to 23 policy-makers representing 15 West African countries participated in the study. Policy-makers who took part in the study supported the development of an EBPM Guidance to facilitate evidence-to-policy process. Among the identified reasons why an EBPM Guidance for West Africa is a necessity were to understand: (i) how to deal with barriers and facilitators that influence evidence to policy process; (ii) how to acquire, access, adapt, and apply available research evidence in policy-making; (iii) how to deal with contextual issues and broad range of evidence; and (iv) how to engage parliamentarians and policy legislators to promote policy development. Conclusion: An EBPM is a valuable tool that can provide health sector policy-makers the needed guide on the evidence-to-policy process. Studies that will evaluate the impact of EBPM guidance on the policy-making process in low- and middle-income countries are advocated.

Résumé Contexte: L'Organisation Ouest Africaine de la Santé (OOAS) encourage l'utilisation de données probantes dans l'élaboration des politiques en Afrique de l'Ouest. La compréhension de la complexité du processus des données probantes aux politiques auprès les décideurs d'Afrique de l'Ouest nécessite l'élaboration d'un guide d'orientation sur l'élaboration de politiques fondées sur des données probantes. L'objectif de cette étude était d'interagir avec les décideurs politiques des pays d'Afrique de l'Ouest afin d'identifier la nécessité d'un guide d'orientation en matière de politiques fondées sur les données probantes pour la sous-région. Méthodes: Une étude qualitative transversale a été utilisée pour obtenir les points de vue/opinions des responsables de la politique de santé des 15 pays d'Afrique de l'Ouest sur les raisons pour lesquelles un guide d'orientation est nécessaire pour la sous-région. Les décideurs ont été sollicités lors des réunions régionales sur l'amélioration des résultats en matière de santé maternelle et infantile organisées par l'OOAS, qui se sont tenues au Sénégal en 2019. Des interactions individuelles en face à face, des entretiens et des délibérations pendant les sessions plénières de la réunion ont été organisés avec les décideurs politiques, qui ont participé à la réunion régionale. Résultats: Au total 23 décideurs politiques représentant 15 pays d'Afrique de l'Ouest ont participé à l'étude. Les décideurs qui ont pris part à l'étude ont soutenu le développement d'un guide d'orientation pour faciliter le processus de mise en relation des données probantes et des politiques. Parmi les besoins identifiés pour un guide d'orientation pour l'Afrique de l'Ouest, il y avait la nécessité de comprendre : (i) comment traiter les obstacles et les facilitateurs qui influencent le processus de mise en pratique des données probantes dans les politiques ; (ii) comment acquérir, accéder, adapter et appliquer les données de recherche disponibles dans l'élaboration des politiques ; (iii) comment traiter les questions contextuelles et le large éventail de données probantes ; et (iv) comment engager les parlementaires et les législateurs politiques à promouvoir le développement des politiques. Conclusion: Un guide d'orientation est un outil précieux qui peut fournir aux décideurs du secteur de la santé les orientations nécessaires sur le processus de mise en relation des données probantes et des politiques. Des études qui évalueront l'impact de ce guide sur le processus d'élaboration des politiques dans les pays à revenu faible et intermédiaire sont préconisées.

The first year of the COVID-19 pandemic in the ECOWAS region.

Objective: to analyse the pandemic after one year in terms of the evolution of morbidity and mortality and factors that may contribute to this evolution. Design: This is a secondary analysis of data gathered to respond to the COVID-19 pandemic. The number of cases, incidence rate, cumulative incidence rate, number of deaths, case fatality rate and their trends were analysed during the first year of the pandemic. Testing and other public health measures were also described according to the information available. Settings: The 15 States members of the Economic Community of West African States (ECOWAS) were considered. Results: As of 31st March 2021, the ECOWAS region reported 429,760 COVID-19 cases and 5,620 deaths. In the first year, 1,110.75 persons were infected per million, while 1.31% of the confirmed patients died. The ECOWAS region represents 30% of the African population. One year after the start of COVID-19 in ECOWAS, this region reported 10% of the cases and 10% of the deaths in the continent. Cumulatively, the region has had two major epidemic waves; however, countries show different patterns. The case fatality rate presented a fast growth in the first months and then decreased to a plateau. Conclusion: We learn that the context of COVID-19 is specific to each country. This analysis shows the importance of better understanding each country's response. During this first year of the pandemic, the problem of variants of concern and the vaccination were not posed. Funding: The study was funded by the International Development Research Centre (IDRC) under CATALYSE project.

Coexistence and management of COVID-19 pandemic with other epidemics in West Africa: lessons learnt and policy implications.

Since the beginning of the COVID-19 pandemic in West Africa, the region has faced a coexistence of epidemics raising questions about the management of the coexistence between COVID-19 and other epidemic prone diseases. We undertook a cross-sectional study covering the period from February to August 2020 in which an extensive desk review was completed and questionnaire was submitted to National Public Health Institutes. In addition, we conducted online interviews with 10 West African countries to discuss in-depth the strategies and challenges in managing the coexistence of epidemics. Eight epidemics coexisted with COVID-19 in West Africa. These epidemics were yellow fever and measles in five countries; meningitis in 4 countries; vaccine derived poliomyelitis and dengue fever in two countries; Lassa fever, Crimean Congo Hemorrhagic fever and hepatitis E virus in one country. COVID-19 pandemic has brought both positive and negative effects to the management of other epidemics. The management of coexistence was similar in most ECOWAS countries with different incident management systems set up to manage separate outbreaks. The experience in managing the coexistence of epidemics led ECOWAS Regional Center for Surveillance and Disease Control to recommend to member states that they should reinforce regular disease surveillance for seasonal outbreaks and country specific epidemiological diseases profile while not forgetting other emerging and remerging infectious diseases.

Operationalizing the ECOWAS regional one health coordination mechanism (2016-2019): Scoping review on progress, challenges and way forward.

Based on recommendations from two consultative meetings held in Dakar, Senegal (2016) and Abuja, Nigeria (2017) the Economic Community of West African States (ECOWAS) implemented a Regional One Health Coordination Mechanism (R-OHCM). This study analyzed the process, challenges and gaps in operationalizing the R-OHCM in West Africa. We utilized a scoping review to assess five dimensions of the operation of an R-OHCM based on political commitment, institutional structure, management and coordination capacity, joint planning and implementation, as well as technical and financial resources. Information was gathered through a desk review, interview of key informants, and the viewpoints of relevant stakeholders from ECOWAS region during a regional One Health technical meeting in Lomé, Togo in October 2019. It was found that political commitment at regional meetings and the countries adoption of regional frameworks were key strengths of the R-OHCM, although there are continued challenges with commitment, sustainability, and variability of awareness about One Health approach. ECOWAS formulated regional strategic documents and operationalized the One Health secretariat for strengthening coordination. The R-OHCM has technical working groups however, there is need for engagement of more specialized workforce and a harmonized reporting structure. Furthermore, inadequate focus on operational research, and weak national OHCM are identified as main gaps. Finally, the support of technical and financial partners will help to address the lack of funding which limits the implementation of the R-OHCM. West Africa has demonstrated profound effort in adopting the One Health approach at regional level but is presently deterred by challenges such as limited skilled One Health workforce, especially in the animal and environmental health sectors, and access to quality of One Health surveillance.

COVID-19 in West Africa: regional resource mobilisation and allocation in the first year of the pandemic.

The world continues to battle the ongoing COVID-19 pandemic. Whereas many countries are currently experiencing the second wave of the outbreak; Africa, despite being the last continent to be affected by the virus, has not experienced as much devastation as other continents. For example, West Africa, with a population of 367 million people, had confirmed 412 178 cases of COVID-19 with 5363 deaths as of 14 March 2021; compared with the USA which had recorded almost 30 million cases and 530 000 deaths, despite having a slightly smaller population (328 million). Several postulations have been made in an attempt to explain this phenomenon. One hypothesis is that African countries have leveraged on experiences from past epidemics to build resilience and response strategies which may be contributing to protecting the continent's health systems from being overwhelmed. This practice paper from the West African Health Organization presents experience and data from the field on how countries in the region mobilised support to address the pandemic in the first year, leveraging on systems, infrastructure, capacities developed and experiences from the 2014 Ebola virus disease outbreak.

COVID-19 pandemic waves: how prepared is West Africa for managing a high COVID-19 caseload? Urgent actions needed.

The ECOWAS Region and the world have learnt a lot in the last year and a half concerning the pandemic. As the pandemic continues to evolve, the region needs to put together all these lessons in other to better protect its people, rebuild its economy and strengthen the regional health security for better regional prosperity. We reviewed the response mounted by the region from January 2020 to July 2021 and the existing body of knowledge. We recommend that the region quickly increase the COVID-19 immunization coverage, sustain the enhance genomic surveillance, improve testing and the strengthen point of entry surveillance.

Strengthening Applied Epidemiology in West Africa: Progress, Gaps, and Advancing a Regional Strategy to Improve Health Security.

The ability to prevent, promptly detect, and appropriately respond to a public health threat is essential for health security. Field epidemiology training has helped increase the quality and quantity of the public health workforce to strengthen disease surveillance, outbreak preparedness and response, and general public health capacity. We conducted a desk review on the status of the Field Epidemiology and Laboratory Training Program model in 16 countries in West Africa. We also developed a questionnaire and shared it with West African Health Organization (WAHO) member states to document their experiences and the status of training in their countries. WAHO organized a regional 3-day consultative meeting with major stakeholders in the region to examine progress, gaps, and challenges, and outline a roadmap to strengthen the Field Epidemiology and Laboratory Training Program. Stakeholders shared their experiences, engaged in discussions to identify strengths and gaps, and made plans on a way forward. Member states are at different levels of implementing field epidemiology and laboratory training programs in their countries, and, therefore, major gaps remain in the number and distribution of trained epidemiologists throughout West Africa. Member states implement different variants of the program and in some instances the same cadre of health workers are trained in different but comparable programs with different funding streams. Two member states had not begun implementing the training program. Developing regional centers of excellence was recommended in the long term while collaboration among member states to train the required number of epidemiologists to fill the acute needs could be helpful in the short and medium term. Curriculum harmonization and expansion, deployment and use of trained epidemiologists, accreditation of training institutions, and generation of indigenous funding streams are recommended to improve the Field Epidemiology and Laboratory Training Program in West Africa.

How does the West African Health Organisation (WAHO) contribute to the evidence based decision-making and practice during COVID-19 pandemic in ECOWAS region?

The COVID-19 pandemic required policy makers to make urgent decisions to limit the spread of the disease. International and regional health bodies and research institutions have a role in supporting decision makers and health actors in providing accurate and timely research evidence and guidance in decision making and practice. In ECOWAS region, the West African Health Organisation (WAHO) has experience in promoting evidence use decision making and practice as part of its role as Health Policy and Research Organisation. Promoting the use of evidence to influence policy and practice is possible through various approaches including training, the development of guides and policy briefs, the synthesis and sharing of evidence, and the organisation of meetings to share experiences. In the context of the COVID-19 pandemic, WAHO has deployed several approaches to bring the use of evidence to decision-makers and stakeholders to influence policy and practice. To improve practices, WAHO has organized regional training workshops on laboratory diagnostic, surveillance and simulation exercises of outbreak response for key actors, as well as webinars on different aspects of COVID-19 pandemic surveillance, coordination and management. In addition, a synthesis of the most recent evidence and epidemiologic models were developed to enlighten decision makers in selecting and implementation response interventions.

Promoting the use of evidence in health policymaking in the ECOWAS region: the development and contextualization of an evidence-based policymaking guidance.

BACKGROUND: The Economic Commission of the West African States (ECOWAS), through her specialised health Institution, the West African Health Organization (WAHO) is supporting Members States to improve health outcomes in West Africa. There is a global recognition that evidence-based health policies are vital towards achieving continued improvement in health outcomes. The need to have a tool that will provide systematic guide on the use of evidence in policymaking necessitated the production of the evidence-based policy-making (EBPM) Guidance. METHODS: Google search was performed to identify existing guidance on EBPM. Lessons were drawn from the review of identified guidance documents. Consultation, interaction and interviews were held with policymakers from the 15 West African countries during WAHO organized regional meetings in Senegal, Nigeria, and Burkina Faso. The purpose was to elicit their views on the strategies to promote the use of evidence in policymaking to be included in the EBPM Guidance. A regional Guidance Validation Meeting for West African policymakers was thereafter convened by WAHO to review findings from review of existing guidance documents and validate the EBPM Guidance. RESULTS: Out of the 250 publications screened, six publications fulfilled the study inclusion criteria and were reviewed. Among the important issues highlighted include: what evidence informed decision-making is; different types of research methods, designs and approaches, and how to judge the quality of research. The identified main target end users of the EBPM Guidance are policy/decision makers in the West African sub-region, at local, sub-national, national and regional levels. Among the key recommendations included in the EBPM Guidance include: properly defining/refining policy problem; reviewing contextual issues; initiating policy priority setting; considering political acceptability of policy; commissioning research; use of rapid response services, use of policy advisory/technical/steering committees; and use of policy briefs and policy dialogue. CONCLUSION: The EBPM Guidance is one of the emerging tools that can enhance the understanding of evidence to policy process. The strategies to facilitate the use of evidence in policymaking outlined in the Guidance, can be adapted to local context, and incorporated validated approaches that can be used to promote evidence-to-policy-to-practice process in West Africa.

Policy dialogue to support maternal newborn child health evidence use in policymaking: The lessons learnt from the Nigeria research days first edition.

The use of evidence in decision-making and practice can be improved through diverse interventions, including policy dialogue. The Department of Family Health, Federal Ministry of Health of Nigeria initiated and organized the Nigeria Research Days (NRD), to serve as a platform for exchange between researchers and policymakers for improving maternal, new-born and child health. The study reports on the conceptualization, organization and lessons learned from the first edition. A cross-sectional study was designed to assess the effectiveness of a policy dialogue during the NRDs. Data were collected from the feasibility and workshop evaluation surveys. A descriptive analysis of data was performed. As a result, the Nigeria Research Days meets all the criteria for a successful policy dialogue. The participants positively rated the content and format of the meeting and made suggestions for improvement. They were willing to implement the recommendations of the final communiqué. The lessons learned from this first edition will be used to improve future editions.

Performance of the Public Health System During a Full-Scale Yellow Fever Simulation Exercise in Lagos State, Nigeria, in 2018: How Prepared Are We for the Next Outbreak?

Recurring outbreaks of infectious diseases have characterized the West African region in the past 4 decades. There is a moderate to high risk of yellow fever in countries in the region, and the disease has reemerged in Nigeria after 21 years. A full-scale simulation exercise of the outbreak of yellow fever was conducted to assess preparedness and response in the event of a full-scale outbreak. The exercise was a multi-agency exercise conducted in Lagos, and it involved health facilities, points of entry, state and national public health emergency operation centers, and laboratories. An evaluation of the exercise assessed the capability of the system to identify, respond to, and recover from the emergency using adapted WHO tools. The majority of participants, observers, and evaluators agreed that the exercise was well-structured and organized. Participants also strongly agreed that the exercise helped them to identify strengths and gaps in their understanding of the emergency response systems and plans. Overall, the exercise identified existing gaps in the current capabilities of several thematic areas involved in a yellow fever response. The evaluation presented an opportunity to assess the response capabilities of multisectoral collaborations in the national public health system. It also demonstrated the usefulness of the exercise in understanding public health officials' roles and responsibilities; enabling knowledge transfer among these individuals and organizations; and identifying specific public health systems-level strengths, weaknesses, and challenges.

Factors Leading to Pregnancies in Stimulated Intrauterine Insemination Cycles and the Use of Consecutive Ejaculations Within a Small Clinic Environment.

INTRODUCTION: Understanding and improving IUI pregnancy rates has enormous global appeal and application. This pilot study goes one step further by utilising consecutive ejaculates from men with oligozoospermia and comparing with normozoospermic male group. MATERIALS AND METHODS: A retrospective analysis was performed on 117 IUI-stimulated treatment cycles in a small fertility clinic in North Middlesex University Hospitals Trust, UK, within a NHS setting. Risks of OHSS and multiple births are carefully controlled. RESULTS: In our cohort, several factors are associated with positive IUI pregnancies and these were: age of the woman, inseminating with ≥5 total progressive motile sperm; having ≥50 % Grade A sperm progression and having ≥1 follicle achieved with a realistic hMG dosage, hCG trigger and IUI of 29.7 h (2.5-38.4 h), with an endometrial thickness of 10.7 mm (6.6-13.4 mm). Bifollicular presence in at least half the cases along with hMG protocols added usefully to the pregnancy outcomes. CONCLUSIONS: The pregnancy rates per cycle were 19 and 23 % in the consecutive ejaculates and non-consecutive ejaculate groups, respectively, P = 0.59. For the whole cohort, the pregnancy rate was 20.51 % per cycle and 33.8 % per women. This approach if validated with large RCT will have universally beneficial effects.

Incidence, aetiology and epidemiology of uterine fibroids.

Uterine fibroids are the most common benign tumour of the female genital tract. However, their true prevalence is probably under-estimated, as the incidence at histology is more than double the clinical incidence. Recent longitudinal studies have estimated that the lifetime risk of fibroids in a woman over the age of 45 years is more than 60%, with incidence higher in blacks than in whites. The cause of fibroids remains unclear and their biology poorly understood. No single candidate gene has been detected for commonly occurring uterine fibroids. However, the occurrence of rare uterine fibroid syndromes, such as multiple cutaneous and uterine leiomyomatosis, has been traced to the gene that codes for the mitochondrial enzyme, fumarate hydratase. Cytogenetic abnormalities, particularly deletions of chromosome 7, which are found in up to 50% of fibroid specimens, seem to be secondary rather than primary events, and investigations into the role of tumour suppressor genes have yielded conflicting results. The key regulators of fibroid growth are ovarian steroids, both oestrogen and progestogen, growth factors and angiogenesis, and the process of apoptosis. Black race, heredity, nulliparity, obesity, polycystic ovary syndrome, diabetes and hypertension are associated with increased risk of fibroids, and there is emerging evidence that familial predisposition to fibroids is associated with a distinct pattern of clinical and molecular features compared with fibroids in families without this prevalence.

Obstetric care of Jehovah's Witnesses: a 14-year observational study.

Over a 14-year period, the obstetric outcome of Jehovah's Witnesses in an inner city hospital was reviewed and the effect of refusal of blood on morbidity and mortality evaluated. Ninety women had 116 deliveries and of these, 24% were delivered by caesarean section, 10% had instrumental deliveries and 66% were normal vaginal deliveries. Postpartum haemorrhage of >1,000 mls occurred in 6% and postpartum anaemia was the commonest complication. The mean postdelivery haemoglobin (11.10 +/- 1.15 g/dl) was not significantly less from the mean predelivery haemoglobin level (11.81 +/- 1.62 g/dl) (P > 0.05, paired t test). The single maternal death occurred after caesarean hysterectomy, which when extrapolated, resulted in a 65-fold increased risk of maternal death compared to the national rate. The optimum management of pregnant women who decline transfusion is discussed.

Fibroids in pregnancy--common but poorly understood.

UNLABELLED: Uterine fibroids are the most common benign tumors in women, occurring in approximately 20% to 30% of women of reproductive age. They are therefore common in pregnancy. The true incidence of fibroids during pregnancy is, however, unknown, but reported rates vary from as low as 0.1% of all pregnancies to higher rates of 12.5%. It seems that pregnancy has little or no effect on the overall size of fibroids despite the occurrence of red degeneration in early pregnancy. Fibroids, however, affect pregnancy and delivery in several ways, with abdominal pain, miscarriage, malpresentation, and difficult delivery being the most frequent complications. The size, location, and number of fibroids and their relation to the placenta are critical factors. Ultrasound scanning plays a central role in diagnosing and monitoring fibroids during pregnancy and in determining the relative position of the fibroids to the placenta. It is equally useful for detecting heterogeneous echo patterns associated with the appearance of pain in pregnancy. Color flow Doppler scanning differentiates fibroids from myometrial thickening, which may be mistaken for fibroids. Few treatment options are available during pregnancy, but in carefully selected patients, myomectomy has been performed successfully without jeopardizing pregnancy outcome. A successful pregnancy and delivery is common with appropriate surveillance and supportive management. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians LEARNING OBJECTIVES: After completion of this article, the reader should be able to summarize the influence of pregnancy on fibroids, to explain the influence of fibroids on pregnancy, and to outline the management of fibroids during pregnancy.
