An analysis of three national health insurance proposals in Sub-Saharan Africa

The financing and/or provision of health insurance by government has a theoretical basis: it stems from market failure in the private health insurance market; and, from externalities in the consumption of health care by the poor. Government health insurance, or national health insurance (NHI) may be analysed by using five criteria: who are the beneficiaries?; efficiency effects; the equity of financing; the level of administrative costs; and, political acceptability. In the last five years, Ghana, Zimbabwe and Nigeria have each considered proposals for NHI. However, each proposal shows design flaws, when analysed in the light of the five criteria above. This article first considers types of health insurance in Sub-Saharan Africa, and why NHI, with cost recovery as an essential component, might be desirable. A following section present an outline of the NHI proposals in Ghana, Zimbabwe and Nigeria and points out the design flaws. A final section builds upon the theoretically-good aspects of the three proposals, and considers some alternate approaches to NHI that these three countries and other countries in the Sub-Sahara might want to consider.     

HIV self-testing in adolescents living in Sub-Saharan Africa

Less than 20% of African adolescents aged 10–19 years are aware of their HIV status, whereas HIV screening remains the gateway to care and while AIDS has become the leading cause of death among adolescents in Sub-Saharan Africa. According to the UNAIDS target, scalable HIV testing strategies specific to various age groups, populations, and geographical areas must be implemented to end the AIDS epidemic by 2030. Many African countries have implemented policies supporting HIV self-testing (HIVST). Evidence of practicability and efficiency of HIVST in Sub-Saharan Africa settings has been reported, including HIVST data among adolescents. Adapted strategies of HIVST are urgently needed to promote HIV testing among adolescents living in sub-Saharan Africa.     

Measles control in Sub-Saharan Africa: South Africa as a case study

Background

Due to intensified measles immunization efforts, measles mortality has decreased substantially worldwide, particularly in Sub-Saharan Africa (SSA). The World Health Organization (WHO) estimated a 92% decrease in measles-related deaths in the WHO AFRO region for the period 2000–2008. Recently, the AFRO region established a measles pre-elimination goal and experts have suggested engaging in a measles eradication campaign at the global level. However, recent large-scale outbreaks in many Sub-Saharan African countries present a challenge to measles control efforts. This paper examines measles immunization and the impact of measles supplemental immunization activities (SIAs) on routine immunization coverage in South Africa (SA).

Methods

We reported on immunization coverage trends in SA for the period 2001–2010 at the province and district levels. The data included routine immunization for 1st and 2nd doses of measles vaccine (MCV1, MCV2), SIAs, 1st dose of Bacille Calmette-Guérin vaccine, 1st and 3rd doses of oral polio vaccine (OPV1, OPV3), 3rd dose of Diphtheria–Tetanus–Pertussis–Haemophilus-influenzae-B vaccine (DTP-Hib3), and the number of under-one-year-olds having completed a primary course of immunization (Imm1). A regression model looked at the SIA impact on routine coverage.

Results

Over the past decade, MCV1 and MCV2 coverage have increased nationally from 68% and 57% in 2001 to 95% and 83% in 2010, respectively. SIA coverage has remained at high levels, around 90%, over the same period. Substantial heterogeneity in MCV1 and MCV2 coverage is present across SA districts, with differences in coverage of 56% (MCV1) and 51% (MCV2) in 2010. In any given year, occurrence of SIAs was associated with a decrease in routine immunization coverage of MCV1, MCV2, OPV1, OPV3, DTP-Hib3, and Imm1, at the district level.

Conclusions

The heterogeneity in measles vaccination coverage across SA districts challenges the goal of measles elimination in SA and SSA. The reduction in routine immunization coverage associated with the occurrence of SIAs raises the legitimate concern that SIAs may negatively impact health systems’ functioning.     

Cost recovery in the health-care sector in Sub-Saharan Africa

Cost recovery, or the pricing of health-care services in government-run health-care facilities, continues to be a politically delicate subject in Sub-Saharan Africa. Nevertheless, ministries of health are now beginning to understand that the selective pricing of healthcare services can be a powerful tool for achieving the efficiency and equity goals that their governments have set, and for increasing ministry financial resources that can be used to improve the quality of care offered. This article provides a blue-print for these nascent cost-recovery efforts. After a consideration of the rationale for cost recovery within a theoretical context, a set of pricing principles for the whole public health sector is presented and a prototypical systemic price schedule is derived from the principles. Constraints to effective and equitable cost recovery are then discussed, and topics for further empirical research are suggested.     

Estimating the welfare gains from anti-retroviral therapy in Sub-Saharan Africa

Since the start of the century, many countries in Sub-Saharan Africa have experienced large gains in life expectancy and average consumption levels. Around the same time, an unprecedented international effort has taken place to combat HIV/AIDS mortality with the expansion of anti-retroviral therapy (ART) across many of the hardest hit countries. In this paper, I estimate the impact of ART on average welfare over time in 42 countries using the equivalent consumption approach. I decompose the change in welfare to isolate the relative contribution of ART-driven improvements in life expectancy and consumption. The results indicate that ART has accounted for around 12% of total welfare growth in SSA between 2000 and 2017. In those countries most affected by HIV/AIDS, this figure rises to around 40%. Moreover, the estimates suggest that welfare in some of the worst-hit countries would have declined over time without the ART expansion.     

Migration of Nurses from Sub-Saharan Africa: A Review of Issues and Challenges

Objective. To assess the impact of out-migration of nurses on the health systems in sub-Saharan Africa (SSA).
Setting. The countries of SSA.
Design and Methods. Review of secondary sources: existing publications and country documents on the health workforce; documents prepared for the Joint Learning Initiative Global Human Resources for Health report, the World Health Organization (AFRO) synthesis on migration, and the International Council of Nurses series on the global nursing situation. Analysis of associated data.
Principal Findings. The state of nursing practice in SSA appears to have been impacted negatively by migration. Available (though inadequate) quantitative data on stocks and flows, qualitative information on migration issues and trends, and on the main strategies being employed in both source and recipient countries indicate that the problem is likely to grow over the next 5–10 years.
Conclusions. Multiple actions are needed at various policy levels in both source and receiving countries to moderate negative effects of nurse emigration in developing countries in Africa; however, critically, source countries must establish more effective policies and strategies.     

Political determinants of progress in the MDGs in Sub-Saharan Africa

Sub-Saharan Africa (SSA) lagged furthest behind in achieving targets for the millennium development goals (MDG). We investigate the hypothesis that its slow progress is influenced by political factors. Longitudinal data on three health MDG indicators: under-five mortality, maternal mortality and HIV prevalence rates were collated from 1990 to 2012 in 48 countries. Countries were grouped into geo-political and eco-political groups. Groupings were based on conflict trends in geographical regions and the International Monetary Fund’s classification of SSA countries based on gross national income and development assistance respectively. Cumulative progress in each group was derived and main effects tested using ANOVA. Correlation analysis was conducted between political variables – POLITY 2, fragile state index (FSI), voter turnout rates, civil liberty scores (CLS) and the health variables. Our results suggest a significant main effect of eco-political and geo-political groups on some of the health variables. Political conflict as measured by FSI and political participation as measured by CLS were stronger predictors of slow progress in reducing under-five mortality rates and maternal mortality ratios. Our findings highlight the need for further research on political determinants of mortality in SSA. Cohesive effort should focus on strengthening countries’ political, economic and social capacities in order to achieve sustainable goals beyond 2015.     

HIV/AIDS and the construction of Sub-Saharan Africa: heuristic lessons from the social sciences for policy

There is no doubt that Sub-Saharan African countries face major problems due to the HIV/AIDS pandemic that has ravaged the region. Yet the Eurocentric construction of the region as the source of the virus not only creates negative stereotypes in social science disciplines like geography, but also glosses over the potential of social science disciplines to provide knowledge and influence policy about HIV/AIDS. This oppositional construction of the region has unfortunately contributed to a glossing over of many aspects of Sub-Saharan Africa's people, their environment, culture, history, politics, economics, gender relations, and the region's global status that would provide important input for policy aimed at curbing the devastating spread of HIV in the region. This paper argues that once we recognize that HIV is a global virus with trans-cultural implications, social science disciplines, such as geography, can reveal certain attributes about the region and its HIV/AIDS pandemic that can be used in policy formulation to combat the spread of the virus.     

Brain death determination: the imperative for policy and legal initiatives in Sub-Saharan Africa

The concept of brain death (BD), defined as irreversible loss of function of the brain including the brainstem, is accepted in the medical literature and in legislative policy worldwide. However, in most of Sub-Saharan Africa (SSA) there are no legal guidelines regarding BD. Hypothetical scenarios based on our collective experience are presented which underscore the consequences of the absence of BD policies in resource-limited countries (RLCs). Barriers to the development of BD laws exist in an RLC such as Kenya. Cultural, ethnic, and religious diversity creates a complex perspective about death challenging the development of uniform guidelines for BD. The history of the medical legal process in the USA provides a potential way forward. Uniform guidelines for legislation at the state level included special consideration for ethnic or religious preferences in specific states. In SSA, medical and social consensus on the definition of BD is a prerequisite for the development BD legislation. Legislative policy will (1) limit prolonged and futile interventions; (2) mitigate the suffering of families; (3) standardise clinical practice; and (4) facilitate better allocation of scarce critical care resources in RLCs. There is a clear-cut need for these policies, and previous successful policies can serve to guide these efforts.     

Prevalence and Factors Associated with the Triple Burden of Malnutrition among Mother-Child Pairs in Sub-Saharan Africa

Despite concerns about the coexistence of overnutrition, undernutrition and micronutrient deficiencies, which is compositely referred to as the triple burden of malnutrition (TBM), little is known about the phenomenon in sub-Saharan Africa (SSA). We, therefore, aimed to examine the prevalence and investigate the factors associated with TBM in SSA. This study uses cross-sectional survey data collected through the Demographic and Health Surveys (DHS) Program from 2010 to 2019. Data from 32 countries in SSA were used for the analysis. The prevalence of TBM were presented in tables and maps using percentages. The predictors of TBM were examined by fitting a negative log-log regression to the data. The results were then presented using adjusted odds ratios (aORs) at 95% Confidence Intervals (CIs). Out of the 169,394 children, 734 (1%) suffered from TBM. The highest proportion of children with TBM in the four geographic regions in SSA was found in western Africa (0.75%) and the lowest in central Africa (0.21%). Children aged 1 [aOR = 1.283; 95% CI = 1.215–1.355] and those aged 2 [aOR = 1.133; 95% CI = 1.067–1.204] were more likely to experience TBM compared to those aged 0. TBM was less likely to occur among female children compared to males [aOR = 0.859; 95% CI = 0.824–0.896]. Children whose perceived size at birth was average [aOR = 1.133; 95% CI = 1.076–1.193] and smaller than average [aOR = 1.278; 95% CI = 1.204–1.356] were more likely to suffer from TBM compared to those who were larger than average at birth. Children born to mothers with primary [aOR = 0.922; 95% CI = 0.865–0.984] and secondary [aOR = 0.829; 95% CI = 0.777–0.885] education were less likely to suffer from TBM compared to those born to mothers with no formal education. Children born to mothers who attended antenatal care (ANC) had lower odds of experiencing TBM compared to those born to mothers who did not attend ANC [aOR = 0.969; 95% CI = 0.887–0.998]. Children born to mothers who use clean household cooking fuel were less likely to experience TBM compared to children born to mothers who use unclean household cooking fuel [aOR = 0.724; 95% CI = 0.612–0.857]. Essentially, higher maternal education, ANC attendance and use of clean cooking fuel were protective factors against TBM, whereas higher child age, low size at birth and being a male child increased the risk of TBM. Given the regional variations in the prevalence and risk of TBM, region-specific interventions must be initiated to ensure the likelihood of those interventions being successful at reducing the risk of TBM. Countries in Western Africa in particular would have to strengthen their current policies and programmes on malnutrition to enhance their attainment of the SDGs.     

Risk Factors for Overweight and Obesity within the Home Environment of Preschool Children in Sub-Saharan Africa: A Systematic Review

Sub-Saharan Africa (SSA) is experiencing an increasing prevalence of young children being overweight and obese. Many feeding and physical activity-related behaviours are established at home during preschool years, yet the precise factors that contribute to preschool overweight and obesity have not been fully elucidated. This review aims to identify factors in the home environment associated with overweight and or obesity in preschool children in SSA. Ovid MEDLINE, EMBASE, CINAHL, Scopus, Web of Science, Africa Journals Online (AJOL) and the African Index Medicus databases were systematically searched for qualitative and quantitative studies published between 2000 and 2021. Eleven studies (ten quantitative, one qualitative) met the inclusion criteria. Overall, the results highlight the paucity of studies exploring factors in the home environment associated with overweight and obesity in preschool children in Sub-Saharan Africa. The home food environment and maternal BMI appear to be important factors associated with overweight and obesity in preschool children; however, the information for all other factors explored remains unclear due to the lack of evidence. For successful obesity prevention and treatment interventions to be developed, more research in this area is required to understand how different aspects of the home environment contribute to overweight and obesity in preschool Sub-Saharan African children.     

Community involvement in health development in post-apartheid South Africa

In this article, some challenges for the implementation of community involvement in health programmes in post-apartheid South Africa are examined. Viewed against the background of racial segregation and inequalities in the South African health system, effective community involvement in health development would be an extension of ongoing democratization in which previously marginalized people in the majority population group are given the opportunity to participate in decisions and programmes affecting their health. This situation calls for sensitivity with respect to the criteria for adopting given models of community involvement and the political correlates of particular health programmes. Also, considerable patience would be required until the belated efforts to produce adequate personnel support for community involvement begins to yield returns, and until the communities experience a level of economic development which can support community health programmes financially.     

Comparative performance of public and private sector delivery of BCG vaccination: Evidence from Sub-Saharan Africa

Background

The private sector is an important source of health care in the developing world. However, there is limited evidence on how private providers compare to public providers, particularly for preventive services such as immunizations. We used data from Sub-Saharan Africa (SSA) to assess public–private differences in Bacillus Calmette–Guérin (BCG) vaccine delivery.

Methods and findings

We used demographic and health surveys from 102,629 children aged 0–59 months from 29 countries across SSA to measure differences in BCG status for children born at private versus public health facilities (BCG is recommended at birth). We used a probit model to estimate public–private differences in BCG delivery, while controlling for key confounders. Next, we estimated how differences in BCG status evolved over time for children born at private versus public facilities. Finally, we estimated heterogeneity in public–private differences based on wealth and rural–urban residency. We found that children born at a private facility were 7.1 percentage points less likely to receive BCG vaccine in the same month as birth than children born at a public facility (95% CI 6.3–8.0; p < 0.001). Most of this difference was driven by for-profit private providers (as opposed to NGOs) where the BCG provision rate was 10.0 percentage points less than public providers (95% CI 9.0–11.2; p < 0.001) compared to only 2.4 percentage points for NGOs (95% CI 1.0–3. 8; p < 0.01). Moreover, children born at private for-profit facilities remained less likely to be vaccinated up to 59 months after birth. Finally, public–private differences were more pronounced for poorer children and children in rural areas.

Conclusions

The for-profit private sector performed substantially worse than the public sector in providing BCG vaccine to newborns, resulting in a longer duration of vulnerability to tuberculosis. This disparity was greater for poorer children and children in rural areas.     

Social capital and access to primary health care in developing countries: Evidence from Sub-Saharan Africa

We test for a causal role of social capital, as measured by self-reported trust, in determining access to basic health facilities in Sub-Saharan Africa. To skirt the reverse-causality problems between social capital and basic health, we rely on instrumental-variable (IV) estimates. A one standard-deviation increase in trust is predicted to lead to a 0.22 standard-deviation fall in doctor absenteeism, a 0.31 standard-deviation fall in waiting time and a 0.30 standard-deviation fall in bribes. As a robustness check, we also use a different database regarding a different health issue, access to clean water. We find that a one standard-deviation rise in trust leads to a 0.33 standard-deviation rise in access to clean water. The variety of public goods considered provides insights about the possible channels through which social capital is converted into health improvements.

Household Food Insecurity,Dietary Diversity,and Stunting in Sub-Saharan Africa: A Systematic Review

Background: The significant public health problem in Sub-Saharan Africa of household food insecurity is an underlying cause of malnutrition in Sub-Saharan Africa. This study aims to systematically study the association between household food insecurity, dietary diversity, and stunting. Methods: This review was carried out based on the recommendations of PRISMA (2015). We searched the literature in six bibliographic databases: PubMed, EMBASE, Science Direct, Web of Science, Google Scholar, and Scopus. The research was based on studies conducted in Sub-Saharan Africa about household food insecurity, dietary diversity, and stunting and was published between 2009 and 2020. Results: Out of 2398 original articles identified, only 21 articles met the specific requirements of this review. Two-thirds of the articles selected showed that stunting was linked to household food insecurity and dietary diversity. Conclusions: This study found that household food insecurity and dietary diversity are significantly associated with stunting in Sub-Saharan Africa. This review recommends that in order to yield a sustainable fight against childhood malnutrition in Sub-Saharan Africa, reliable guidelines and strategies are needed to address these factors related to malnutrition.     

Acceptability of Vegetable Fortified Ugali in Sub-Saharan Africa

Corn flour-based porridge like dough, ugali, is the staple food of low-income population in sub-Saharan Africa. Lack of vitamin A, carotenoids, and dietary fibers brings about serious health issues to this population. In this study, vegetables including bok choy, broccoli, cabbage, carrot, Chinese onion stalk (C_onion), mushroom, are added during the cooking of ugali, as nutritional supplements. The freeze-dried powder of each vegetable was used for its long storage, stable nutrients, and similar particle size. Sub-Saharan African assessors were trained and sensory evaluated the six different vegetable fortified ugali with the plain, unfortified as the control on five attributes. The plain ugali was indistinguishable with the C_onion stalk fortified in color, with the carrot and C_onion stalk fortified in odor, with all vegetables (except broccoli and mushroom) fortified ugali in taste, with carrot and C_onion stalk fortified in granularity, and with cabbage, carrot, C_onion stalk fortified in viscosity. Preference ranking analysis showed that the C_onion stalk fortified ugali is even more favorably preferred than the plain, unfortified ugali, probably due to the umami components in C_onion that serve as the taste enhancer. This study indicates that Chinese onion stalk is a potential vegetable supplement to population in the sub-Saharan Africa.     

Birth intervals and injectable contraception in sub-Saharan Africa

OBJECTIVE: The interval between births is associated with child survival in the developing world. We aimed to investigate associations between use of depot-medroxyprogesterone acetate and other reversible contraception and short birth intervals in sub-Saharan Africa. METHODS: Data from successive Demographic and Health Surveys undertaken in nine African countries were analyzed. Logistic regression was used to explain changes in the proportion of short birth intervals in four countries with relatively high use of reversible contraception. FINDINGS: The overall odds ratio for the trend was 0.90 (95% CI 0.84 to 0.95) and this was unaffected by adjusting for the other variables. The odds of a short birth interval were reduced by exclusive breastfeeding (OR 0.67, 95% CI 0.58 to 0.78) and increased by use of injectable contraception (OR 1.23, 95% CI 1.11 to 1.38). CONCLUSION: The proportion of short birth intervals has changed little over the last decade in a context of very low use of the intrauterine device. Widespread adoption of injectable contraception is associated with greater odds of a short birth interval, thus not contributing favorable conditions for improved child health.     

Health system financing by social security.

The article reviews, through a historical perspective, the development world-wide in social security systems for financing health care, considers the various patterns of health care funded by such systems, and identifies a number of the strengths and alleged weaknesses of the health insurance concept especially in the developing world. Though a range of options exists for mobilizing additional resources to the health sector, the adoption of statutory health insurance stands out as the single most practical strategy for increasing expenditures in health systems--especially expenditures on organized patterns of delivering primary health care.
