The Value Proposition of Coordinated Population Cohorts Across Africa.

Building longitudinal population cohorts in Africa for coordinated research and surveillance can influence the setting of national health priorities, lead to the introduction of appropriate interventions, and provide evidence for targeted treatment, leading to better health across the continent. However, compared to cohorts from the global north, longitudinal continental African population cohorts remain scarce, are relatively small in size, and lack data complexity. As infections and noncommunicable diseases disproportionately affect Africa's approximately 1.4 billion inhabitants, African cohorts present a unique opportunity for research and surveillance. High genetic diversity in African populations and multiomic research studies, together with detailed phenotyping and clinical profiling, will be a treasure trove for discovery. The outcomes, including novel drug targets, biological pathways for disease, and gene-environment interactions, will boost precision medicine approaches, not only in Africa but across the globe.

Medical abortion in Ghana: A non-randomized, non-inferiority study of access through pharmacies compared with clinics.

OBJECTIVES: To compare self-reported clinical outcomes following medical abortion with mifepristone and misoprostol sourced from either a pharmacy or health clinic. STUDY DESIGN: We conducted a prospective, non-randomized, non-inferiority cohort study across four regions in Ghana, from high-volume pharmacies and health clinics. Participants seeking medical abortion (less than nine weeks' gestation) who met usual medical abortion eligibility criteria were recruited. Data collection included baseline surveys, follow-up phone interviews, and self-reported assessments of medical abortion outcomes. The study aimed to enroll 2000 medical abortion users (1000 from each source). RESULTS: Complete outcome data was available and analyzed from 1958 participants (of 2208 enrolled), with the adjusted risk difference of need for additional treatment to complete the abortion indicating non-inferiority of the pharmacy group compared to the clinic group [-2.3% (95% CI -5.3% to 0.7%)]. Both groups reported low rates of additional treatment (4.9%) and adhered similarly to the abortion regimen. Secondary outcomes showed no significant differences, with moderate acceptability in both groups (65.4% pharmacy, 52.3% facility). Adverse outcomes were rare: one ectopic pregnancy, one blood transfusion and no deaths or other major complications were reported. CONCLUSIONS: Accessing medical abortion pills directly from pharmacies without prior consultation from a provider demonstrated non-inferior self-reported clinical outcomes compared to seeking care from health clinics. The findings align with the growing global evidence supporting the safety and effectiveness of medical abortion self-care. IMPLICATIONS: This study contributes data which support future registration of over-the-counter use of medical abortion drugs up to nine weeks' gestation. Such measures could expand options for safe abortion care, especially in regions where unsafe abortion poses a substantial maternal health risk. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03727308).

Contraceptive use and method mix dynamics in Sub-saharan Africa: time trends and the influence of the HIV pandemic.

BACKGROUND: Contraceptive use dynamics continue to be of priority in sub-Saharan Africa because of persistently high levels of fertility. This paper focuses on the use of barrier versus non-barrier contraceptive use in sub-Saharan Africa hypothesizing that the HIV pandemic in the region would be responsible for increases in the use of barrier methods over time. METHODS: This paper uses Demographic and Heath Survey (DHS) data from 32 countries to conduct extensive analysis of trends in contraceptive use and method mix that refers to the distribution of contraceptive methods use among the sexually active population. The paper examines how contraceptive method mix dynamics have changed over time and whether the trends differ by marital status and gender using cross-tabulations. It furthers examines the determinants of method choice using logistic regressions. RESULTS: The findings indicate that the use of barrier methods, most markedly for unmarried women and men, rose substantially between the late 1980s and late 2000s in the region in tandem with trends in HIV prevalence. The results further show marked differences in method mix by gender with men being more likely to report barrier method use than women. CONCLUSIONS: The findings indicate shifting preferences in contraceptive choice. The time trend analyses highlight the importance of expanding the focus of contraceptive use studies beyond women in this context as the study finds differing trends for men.

Impact of health system strengthening interventions on child survival in sub-Saharan Africa: a systematic review protocol.

BACKGROUND: Strengthening healthcare systems is a practical approach to enhance healthcare delivery and services. Although there has been a rise in the number of health systems strengthening (HSS) interventions in sub-Saharan Africa (SSA), there is limited evidence on the causal effect of these activities on child survival. Furthermore, the findings reported so far have been varied, and how they relate to each other remains unclear. This systematic review study aims to assess all available evidence to understand the impact of HSS activities on child survival in SSA. METHODS: We developed a search strategy to retrieve all relevant studies from electronic databases such as PubMed/MEDLINE, Web of Science, and African Journals Online. We will use a combination of search terms such as "under-five mortality," "child mortality," "infant mortality," "neonatal mortality," "child survival," and "health systems strengthening." The review will include studies that establish a causal relationship between HSS interventions and child survival. This will include studies with designs such as randomized controlled trials and quasi-experimental and methods like difference-in-difference. Two reviewers will independently screen all citations, abstracts, and full-text data and a third reviewer will act as a tiebreaker in case of disagreements. The primary outcome of interest is the impact of HSS activities on under-five survival. We will evaluate the quality of each study using the Bradford Hill criteria for causation. DISCUSSION: Our systematic review will identify and evaluate all relevant evidence that establishes a causal relationship between HSS activities and the survival of children under five years in SSA. The review's findings regarding the impact of HSS activities on child survival could be of significant interest to the donor community and policy actors in the region. We also anticipate that the review's conclusions could serve as a valuable guide for the development of future health system interventions and strategies in SSA.

Identifying deprived "slum" neighbourhoods in the Greater Accra Metropolitan Area of Ghana using census and remote sensing data.

Background: Identifying urban deprived areas, including slums, can facilitate more targeted planning and development policies in cities to reduce socio-economic and health inequities, but methods to identify them are often ad-hoc, resource intensive, and cannot keep pace with rapidly urbanizing communities. Objectives: We apply a spatial modelling approach to identify census enumeration areas (EAs) in the Greater Accra Metropolitan Area (GAMA) of Ghana with a high probability of being a deprived area using publicly available census and remote sensing data. Methods: We obtained United Nations (UN) supported field mapping data that identified deprived "slum" areas in Accra's urban core, data on housing and population conditions from the most recent census, and remotely sensed data on environmental conditions in the GAMA. We first fitted a Bayesian logistic regression model on the data in Accra's urban core (n=2,414 EAs) that estimated the relationship between housing, population, and environmental predictors and being a deprived area according to the UN's deprived area assessment. Using these relationships, we predicted the probability of being a deprived area for each of the 4,615 urban EAs in GAMA. Results: 899 (19%) of the 4,615 urban EAs in GAMA, with an estimated 745,714 residents (22% of its urban population), had a high predicted probability (≥80%) of being a deprived area. These deprived EAs were dispersed across GAMA and relatively heterogeneous in their housing and environmental conditions, but shared some common features including a higher population density, lower elevation and vegetation abundance, and less access to indoor piped water and sanitation. Conclusion: Our approach using ubiquitously available administrative and satellite data can be used to identify deprived neighbourhoods where interventions are warranted to improve living conditions, and track progress in achieving the Sustainable Development Goals aiming to reduce the population living in unsafe or vulnerable human settlements.

Impact of community health interventions on maternal and child health indicators in the upper east region of Ghana.

BACKGROUND: This paper reports on results of a health system strengthening implementation research initiative conducted the Upper East Region of northern Ghana. Transformative interventions to accelerate and strengthen the health delivery were implemented that included empowering community leaders and members to actively participate in health delivery, strengthening the referral systems through the provision of community transport systems, providing basic medical equipment to community clinics, and improving the skills of critical health staff through training. METHODS: A mixed method design was used to evaluate the impact of the interventions. A quantitative evaluation employed a flexible research design to test the effects of various component activities of the project. To assess impact, a pre-versus-post randomized cluster survey design was used. Qualitative research was conducted with focus group data and individual in depth interviews to gauge the views of various stakeholders associated with the implementation process. RESULTS: After intervention, significant improvements in key maternal and child health indicators such as antenatal and postnatal care coverage were observed and increases in the proportion of deliveries occurring in health facilities and assisted by skilled health personnel relative to pre-intervention conditions. There was also increased uptake of oral rehydration salts (ORS) for treatment of childhood diarrhoea, as well as marked reductions in the incidence of upper respiratory infections (URI). CONCLUSIONS: A pre-and post-evaluation of impact suggests that the programme had a strong positive impact on the functioning of primary health care. Findings are consistent with the proposition that the coverage and content of the Ghana Community-based Health Planning and Services programme was improved by program interventions and induced discernable changes in key indicators of health system performance.

How different incentives influence reported motivation and perceptions of performance in Ghanaian community-based health planning and services zones.

BACKGROUND: Maternal mortality is still a burden worldwide, and Ghana's maternal and child mortalities are still high. Incentive schemes have been effective in improving health workers' performance thereby reducing maternal and child deaths. The efficiency of public health services in most developing countries has been linked to the provision of incentives. Thus, financial packages for Community Health Volunteers (CHVs) serve as enablers for them to be focused and committed to their work. However, the poor performance of CHVs is still a challenge in health service delivery in many developing countries. Although the reasons for these persistent problems are understood, we need to find out how to implement what works in the face of political will and financial constraints. This study assesses how different incentives influence reported motivation and perceptions of performance in Community-based Health Planning and Services Program (CHPS) zones in the Upper East region. METHODS: A quasi-experimental study design with post-intervention measurement was used. Performance-based interventions were implemented for 1 year in the Upper East region. The different interventions were rolled out in 55 of 120 CHPS zones. The 55 CHPS zones were randomly assigned to four groups: three groups of 14 CHPS zones with the last group containing 13 CHPS zones. Several alternative types of financial and non-financial incentives as well as their sustainability were explored. The financial incentive was a small monthly performance-based Stipend. The non-financial incentives were: Community recognition; paying for National Health Insurance Scheme (NHIS) premiums and fees for CHV, one spouse, and up to two children below 18 years, and; quarterly performance-based Awards for best-performing CHVs. The four groups represent the four different incentive schemes. We conducted 31 In-depth interviews (IDIs) and 31 Focus Group Discussions (FGDs) with health professionals and community members. RESULTS: Community members and the CHVs wanted the stipend as the first incentive but requested that it be increased from the current level. The Community Health Officers (CHOs) prioritized the Awards over the Stipend because they felt it was too small to generate the required motivation in the CHVs. The second incentive was the National Health Insurance Scheme (NHIS) registration. Community recognition was also considered by health professionals as effective in motiving CHVs and work support inputs and CHVs training helped in improving output. The various incentives have helped increase health education and facilitated the work of the volunteers leading to increased outputs: Household visits and Antenatal Care and Postnatal Care coverage improved. The incentives have also influenced the initiative of volunteers. Work support inputs were also regarded as motivators by CHVs, but the challenges with the incentives included the size of the stipend and delays in disbursement. CONCLUSION: Incentives are effective in motivating CHVs to improve their performance, thereby improving access to and use of health services by community members. The Stipend, NHIS, Community recognition and Awards, and the work support inputs all appeared to be effective in improving CHVs' performance and outcomes. Therefore, if health professionals implement these financial and non-financial incentives, it could bring a positive impact on health service delivery and use. Also, building the capacities of CHVs and providing them with the necessary inputs could improve output.

"The trip actually opened our eyes to things that we were supposed to do and we were not doing": developing primary health care system leadership in a low-income country with peer exchanges.

BACKGROUND: Health care systems in low and middle-income countries are decentralizing and devolving power to the periphery. Transferring power without systematic processes to develop and nurture leaders at the district compromises the effectiveness and sustainability of the decentralized health system. To address this problem, we developed an approach to leadership learning by observation and experience that improved the organization and performance of the health care system in a district in Ghana. METHODOLOGY: Using two rounds of a longitudinal qualitative study, the study explores the determinants of implementing the Community-Based Health Planning and Services (CHPS) initiative in a district in Ghana. Insights were gained concerning the leadership regimes of two leaders who administered health services in a common geographic area at different points in time with remarkably contrasting outcomes. Insights of health workers who participated in both periods were elicited to clarify interview contexts. Ten focus group discussions (FGDs) and five expert interviews were conducted for each round of the study. The study was informed by a systems appraisal approach that utilized a thematic analytical framework. RESULTS: Providing district leaders with a practical observational experience had a significant influence on health care delivery in all aspects of health care provision at the district level. Exposing participants to models of best practices facilitated the replication of processes that improved the conduct of service delivery and CHPS implementation. Upon reflection, district leaders attributed performance constraints to their lack of understanding of practical ways of responding to complex district health system development needs. Observation from community members, volunteers, and health workers who witnessed the system development period corroborated narratives that leaders had expressed. CONCLUSION: Effective leadership is optimally developed with participatory learning that provides leaders with direct access to fully functioning systems. Learning by observation can be structured and used to quicken the spread of managerial excellence.

Postpartum contraceptive initiation and use: Evidence from Accra, Ghana.

BACKGROUND: Postpartum contraceptive use reduces unintended pregnancies and results in better health outcomes for children and women. However, there is a dearth of knowledge on postpartum contraceptive use in Ghana, particularly among women in low-income urban settings. To shed light on strategies that might enhance access to postpartum family planning services in low-income urban settings, we examined contraceptive use among postpartum women in Accra, Ghana, at 1, 3, 6, and 12 months following the birth and the methods used. The predictors of modern contraceptive use in the 12-month postpartum period were also examined. METHODS: Data come from a cross-sectional survey conducted in 2018 among 624 women aged 16-44 years who reported giving birth in the past 13-31 months prior to the interview. We generated descriptive statistics to examine the prevalence of contraceptive use among postpartum women at 1, 3, 6, and 12 months after birth. We further estimated a binary logistic regression to examine the predictors of modern contraceptive use at 12 months postpartum. RESULTS: Forty percent of postpartum women never used any contraceptive method during 1 year after birth and of those who used a method, 40% relied on traditional methods. Moreover, 29% of women started using a method the immediate 1 month post-birth. Results further show that postpartum modern contraceptive uptake was positively associated with higher education, having more live births, and being currently in a union. CONCLUSIONS: Findings highlight that there may be opportunities to improve the quality of counseling during antenatal and postnatal care visits by clients to ensure fully informed choices regarding postpartum contraception. Community outreach by health providers/promoters or similar models should be promoted in low-income population settings to educate postpartum women on modern contraceptive use. Women who plan to use traditional methods should be provided with information on the consistent and correct use of these methods.

Covert Contraceptive Use amongst the urban poor in Accra, Ghana: experiences of health providers.

BACKGROUND: An estimated one-third of women in Ghana use contraceptives without the knowledge of their partners, a phenomenon known as Covert Contraceptive Use (CCU). Most research on CCU to date has focused on individual women to the neglect of the role of health system. This study explores CCU in urban poor communities of Accra, Ghana, from the experiences and perspectives of health providers. METHODS: Qualitative in-depth interviews were conducted with health care providers in both the public and private sectors at multiple levels, from the community clinic to the tertiary hospital, to gain insights into the strategies women use and the ways in which the health system supports the practice of CCU. RESULTS: Five major thematic areas emerged: use of easily concealed-methods, discrete-access-and-information-keeping, time-of-day, non-verbal-communication and use of relationships. The study further revealed that fear, mistrust, shyness, myths, and misperceptions regarding contraceptives explain CCU among women in the communities that the providers serve. CONCLUSION: Importantly, disclosure of methods used by providers without women's consent could potentially lead to violent outcomes for both women and the providers. Our results highlight the pivotal role that providers play in confidentially supporting women's choices regarding the use of contraceptives.

Sometimes women use contraceptives without the knowledge of their sexual partners. That is to say, they hide their contraceptive use. Many studies have explored why women hide their contraceptive use. Reasons include the desire of men to have absolute control of their women's bodies including their sexuality and fertility regulation. This occurs in cultures where women do not have as much power as men. In Ghana, as much as one-in-three women hide their contraceptive use from their partners. This study explores the ways in which health facilities assist women to hide their contraceptives use by talking to leaders of units responsible for providing contraceptives in the hospitals. First, people prefer contraceptives like injectables that are not visible on the bodies of those using them. Second, some hospitals have modified their space to provide ample privacy and security for women. Third, some women visit the facilities at odd hours, such as very early in the morning, very late at night and at other favorable times. Sometimes nurses arrange to meet women outside the facility. Lastly, nurses create avenues through various personal relationships. For example, leaving their contacts in market spaces and arranging meeting places with market queens.

"You Can't Look at an Orange and Draw a Banana": Using Research Evidence to Develop Relevant Health Policy in Ghana.

We examined factors that either enabled or inhibited the process of evidence-based decision making regarding health policy in Ghana. We conducted qualitative interviews with 2 major groups of stakeholders: health policy and systems research producers (research producers [RPs]) and policy makers (PMs). In-depth interviews were conducted with 12 RPs, who were representatives from 11 health policy and systems research institutions; and 12 PMs working in various national health-related agencies, ministries, and departments. We analyzed the data using the thematic analysis approach. Interview results showed 5 recurring themes in their discussion of enablers and inhibitors of the evidence-to-policy process: (1) the quality, relevance, and quantity of available research evidence; (2) how findings are communicated to PMs; (3) the strength of relationships between RPs and PMs; (4) available structures that promote evidence-based policy making; and (5) the political context in which research and policy making occurs. These findings point to some specific areas for further collaboration and communication among Ghanaian stakeholders to ensure that appropriate health policies are developed from an evidence base.

Health Policy and Systems Research Capacities in Ethiopia and Ghana: Findings From a Self-Assessment.

INTRODUCTION: Health systems are complex. Policies targeted at health system development may be informed by health policy and systems research (HPSR). This study assesses HPSR capacity to generate evidence and inform policy in Ethiopia and Ghana. METHODS: We used a mixed-methods approach including a self-administered survey at selected HPSR institutes and in-depth interviews of policy makers. RESULTS: Both countries have limited capacity to generate HPSR evidence, especially in terms of mobilizing adequate funding and retaining a critical number of competent researchers who understand complex policy processes, have the skills to influence policy, and know policy makers' demands for evidence. Common challenges are limited government research funding, rigidity in executing the research budget, and reliance on donor funding that might not respond to national health priorities. There are no large research programs in either country. The annual number of HPSR projects per research institute in Ethiopia (10 projects) was higher than in Ghana (2.5 projects), Ethiopia has a significantly smaller annual budget for health research. Policy makers in the 2 countries increasingly recognize the importance of evidence-informed policy making, but various challenges remain in building effective interactions with HPSR institutes. CONCLUSION: We propose 3 synergistic recommendations to strengthen HPSR capacity in Ethiopia and Ghana. First, strengthen researchers' capacity and enhance their opportunities to know policy actors; engage with the policy community; and identify and work with policy entrepreneurs, who have attributes, skills, and strategies to achieve a successful policy. Second, deliver policy-relevant research findings in a timely way and embed research into key health programs to guide effective implementation. Third, mobilize local and international funding to strengthen HPSR capacities as well as address challenges with recruiting and retaining a critical number of talented researchers. These recommendations may be applied to other low- and middle-income countries to strengthen HPSR capacities.

Using Health Systems and Policy Research to Achieve Universal Health Coverage in Ghana.

Ghana is positioned to become the first country in sub-Saharan Africa to implement universal health coverage based on nationwide expansion of geographic access through the Community-based Health Planning and Services initiative. This achievement is the outcome of 3 decades of implementation research that health authorities have used for guiding the development of its primary health care program. This implementation research process has comprised Ghana's official endorsement of the 1978 Alma Ata Declaration, leading to the institutionalization of evidence relevant to the strategic design of primary health care and national health insurance policies and services. Rather than relying solely upon the dissemination of project results, Ghana has embraced a continuous and systemic process of knowledge capture, curation, and utilization of evidence in expanding geographic access by a massive expansion in the number of community health service points that has taken decades. A multisectoral approach has been pursued that has involved the creation of systematic partnerships that included all levels of the political system, local development officials, community groups and social networks, multiple university-based disciplines, external development partners, and donors. However, efforts to achieve high levels of financial access through the roll-out of the National Health Insurance Scheme have proceeded at a less consistent pace and been fraught with many challenges. As a result, financial access has been less comprehensive than geographical access despite sequential reforms having been made to both programs. The legacy of activities and current research on primary health care and national health insurance are reviewed together with unaddressed priorities that merit attention in the future. Factors that have facilitated or impeded progress with research utilization are reviewed and implications for health systems strengthening in Ghana and elsewhere in Africa and globally are discussed.

Spatial heterogeneity in drinking water sources in the Greater Accra Metropolitan Area (GAMA), Ghana.

Universal access to safe drinking water is essential to population health and well-being, as recognized in the Sustainable Development Goals (SDG). To develop targeted policies which improve urban access to improved water and ensure equity, there is the need to understand the spatial heterogeneity in drinking water sources and the factors underlying these patterns. Using the Shannon Entropy Index and the Index of Concentration at the Extremes at the enumeration area level, we analyzed census data to examine the spatial heterogeneity in drinking water sources and neighborhood income in the Greater Accra Metropolitan Area (GAMA), the largest urban agglomeration in Ghana. GAMA has been a laboratory for studying urban growth, economic security, and other concomitant socio-environmental and demographic issues in the recent past. The current study adds to this literature by telling a different story about the spatial heterogeneity of GAMA's water landscape at the enumeration area level. The findings of the study reveal considerable geographical heterogeneity and inequality in drinking water sources not evidenced in previous studies. We conclude that heterogeneity is neither good nor bad in GAMA judging by the dominance of both piped water sources and sachet water (machine-sealed 500-ml plastic bag of drinking water). The lessons from this study can be used to inform the planning of appropriate localized solutions targeted at providing piped water sources in neighborhoods lacking these services and to monitor progress in achieving universal access to improved drinking water as recognized in the SDG 6 and improving population health and well-being.

The impact of a health systems strengthening initiative on child morbidity: The case of the Ghana Essential Health Interventions Program in rural northern Ghana.

BACKGROUND: Improving child and maternal health remains a core objective of global health priorities, extending from the millennium development goal (MDG) era to the current focus on the Sustainable Development Goals (SGDs). This paper analyses the childhood morbidity effects of the Ghana Essential Heath Interventions Program (GEHIP), a community-based health systems strengthening in rural northern Ghana. GEHIP was a five-year embedded implementation science plausibility trial that implemented a set of health systems strengthening strategies and tested the proposition that their combined effect at the district, subdistrict and community levels could foster effective community engagement and thereby improve maternal and child health outcomes. METHODS: A two stage random sample survey of reproductive-aged women residing in treatment and comparison districts at the GEHIP baseline and end line was used for Heckman Difference-in-differences (DiD) regression models for estimating the incremental effect of GEHIP exposure on three child morbidity conditions (diarrhea, fever and cough), as recalled by maternal respondents in the course of survey interviews. RESULTS: After controlling for child age and gender, maternal age, education, marital status, health insurance status, religion, ethnicity, occupation and household wealth index, regression results show that GEHIP had a statistically significant 45% reduction in fever (OR = 0.55, CI = 0.31-0.98) and 47% reduction in cough (OR = 0.53, CI = 0.30-0.94), over and above temporal reductions that prevailed in study districts. Although not significant, GEHIP also had 38% reduction in the incidence of diarrhea. CONCLUSION: Previous research has shown that GEHIP had a pronounced positive effect with a reduction in mortality. Our results show that household location in GEHIP districts also led to a significant reduction in morbidity due to cough and fever among under-five children. This association is a likely outcome of GEHIP's impact on the accessibility of primary health care services. Results lend further support to the growing body of evidence that strengthening health systems in rural Africa through the provision of community-based strategies enhances prospects for achieving the United Nations child health SDGs.

Partner support and women's contraceptive use: insight from urban poor communities in Accra, Ghana.

BACKGROUND: Despite the benefits associated with contraceptive use, there is a low prevalence of contraceptive use in sub-Saharan Africa and Ghana. Previous studies have partly and consistently attributed the low prevalence of contraceptive use to partner opposition. However, little is known about the influence of men in contraceptive related choices of their partners, particularly within the context of urban poverty. This study examines the influences of partners on women's contraceptive choices. METHODS: The study utilized a cross-sectional household survey data of 1578 currently married women and women in a union of reproductive ages 16-44 years. Women who were pregnant and those trying to be pregnant were excluded from the analysis. The dependent variables for the study were current use of any contraceptive method, types of contraceptive methods and types of modern contraceptive methods. The independent variable for the study was a woman's report of partner support in contraceptive related choices. A binary logistic regression model was used to examine the associations between partner support in contraceptive related choices and contraceptive use of women. RESULTS: The results of the study show that partner support of contraceptive related choices has a significant influence on contraceptive use of women. Women who indicated support from their partners were more likely to be current users of any contraceptive method, yet were less likely to use modern contraceptive methods. CONCLUSION: The study highlights the need to involve men in family planning programs and research, as well as educating them on the various contraceptive modern methods and the side effects.

Earth System's Gatekeeping of "One Health" Approach to Manage Climate-Sensitive Infectious Diseases.

Global response to climate-sensitive infectious diseases has been uncertain and slow. The understanding of the underlying vulnerabilities which forms part of changes created by forces within the Earth system has never before been critical until the coronavirus disease 2019, "COVID-19" pandemic with the initial developmental phase linked to weather elements and climate change. Hence, the heightened interest in climate-sensitive infectious diseases and GeoHealth, evident in the renewed calls for "One Health" approach to disease management. "One Health" explains the commonality of human and animal medicine, and links to the bio-geophysical environment, yet are at crossroads with how forces within the Earth system shape etiologies, incidences, and transmission dynamics of infectious diseases. Hence, the paper explores how these forces, which are multistage and driven by climate change impacts on ecosystems affect emerging infectious diseases, leading to the question "what drive the drivers of diseases?" Three questions that challenge broad theories of Earth system science on boundaries and connectivity emerged to guide study designs to further interrogating disease surveillance and health early warning systems. This is because, climate change (a) drives prevailing biological health hazards as part of forces within the Earth system, (b) shifts disease control services of ecosystems and functioning to effectively regulate disease incidence, and (c) modifies pathogen-species hosts relationships. Hence, the need to rethink pluralistic concepts of climate-sensitive diseases in their infection and management from a GeoHealth perspective, which "One Health" potentially conveys, and to also maintain ecosystem health.

Impact of Covid-19 on Maternal Health Seeking in Ghana.

The Covid-19 pandemic is widely speculated to have disrupted the delivery of primary health care in low-income countries. Yet, there is little rigorous empirical research identifying this effect. This paper estimates the impact of Covid-19 on facility and skilled delivery and utilisation of antenatal care (ANC) services by comparing these outcomes for women who were pregnant/delivered before and during the Covid-19 period. The results show that Covid-19 led to 23% and 25% reductions, respectively, in the likelihood of facility delivery and four or more ANC visits during pregnancy. These findings highlight the need to build more resilient health systems in low-income settings.

Quantifying within-city inequalities in child mortality across neighbourhoods in Accra, Ghana: a Bayesian spatial analysis.

OBJECTIVE: Countries in sub-Saharan Africa suffer the highest rates of child mortality worldwide. Urban areas tend to have lower mortality than rural areas, but these comparisons likely mask large within-city inequalities. We aimed to estimate rates of under-five mortality (U5M) at the neighbourhood level for Ghana's Greater Accra Metropolitan Area (GAMA) and measure the extent of intraurban inequalities. METHODS: We accessed data on >700 000 women aged 25-49 years living in GAMA using the most recent Ghana census (2010). We summarised counts of child births and deaths by five-year age group of women and neighbourhood (n=406) and applied indirect demographic methods to convert the summaries to yearly probabilities of death before age five years. We fitted a Bayesian spatiotemporal model to the neighbourhood U5M probabilities to obtain estimates for the year 2010 and examined their correlations with indicators of neighbourhood living and socioeconomic conditions. RESULTS: U5M varied almost five-fold across neighbourhoods in GAMA in 2010, ranging from 28 (95% credible interval (CrI) 8 to 63) to 138 (95% CrI 111 to 167) deaths per 1000 live births. U5M was highest in neighbourhoods of the central urban core and industrial areas, with an average of 95 deaths per 1000 live births across these neighbourhoods. Peri-urban neighbourhoods performed better, on average, but rates varied more across neighbourhoods compared with neighbourhoods in the central urban areas. U5M was negatively correlated with multiple indicators of improved living and socioeconomic conditions among peri-urban neighbourhoods. Among urban neighbourhoods, correlations with these factors were weaker or, in some cases, reversed, including with median household consumption and women's schooling. CONCLUSION: Reducing child mortality in high-burden urban neighbourhoods in GAMA, where a substantial portion of the urban population resides, should be prioritised as part of continued efforts to meet the Sustainable Development Goal national target of less than 25 deaths per 1000 live births.

Social and demographic correlates of cardiovascular mortality in the Kassena-Nankana districts of Ghana: a verbal post-mortem analysis.

BACKGROUND: The burden of cardiovascular disease (CVD) in Ghana is rising, but details on its epidemiology are scarce. We sought to quantify mortality due to CVD in two districts in rural Ghana using verbal post-mortem (VPM) data. METHODS: We conducted a proportional sub-hazards analysis of 10 232 deaths in the Kassena-Nankana East and West districts from 2005 to 2012, to determine adult mortality attributed to CVD over time. We stratified results by age, gender and socio-economic status (SES), and compared CVD mortality among SES and gender strata over time. A competing risk model estimated the cumulative effect of eliminating CVD from the area. RESULTS: From 2005 to 2012, CVD mortality more than doubled overall, from 0.51 deaths for every 1000 person-years in 2005 to 1.08 per 1000 person-years in 2012. Mortality peaked in 2008 at 1.23 deaths per 1000 person-years. Increases were comparable in men (2.0) and women (2.3), but greater among the poorest residents (3.3) than the richest (1.3), and among persons aged 55-69 years (2.1) than those aged ≥70 years (1.8). By 2012, male and female CVD mortality was highest in middle-SES persons. We project that eliminating CVD would increase the number of individuals reaching age 73 years from 35% to 40%, adding 1.6 years of life expectancy. CONCLUSIONS: The burden of CVD on overall mortality in the Upper East Region is substantial and markedly increasing. CVD mortality has especially increased in lower-income persons and persons in middle age. Further initiatives for the surveillance and control of CVD in these vulnerable populations are needed.
