Cereal Prices and Child Undernutrition in Ethiopia
(Taylor and Francis, 2021-07-06)This paper looks at how changing cereal prices affect child undernutrition in Ethiopia. It derives height for age (stunting) and weight for height (wasting) as indicators of child undernutrition from the two most recent years of the Livings Standards Measurement Survey and utilizes market prices for key cereals, teff, wheat, and maize at the enumeration area across all regions of the country. Using a panel data fixed effects model, the analysis finds that, contrary to previous studies, rising cereal prices are positively associated with improved child stunting rates for children between ages 6 months and 5 years. There is no evidence to suggest that cereal prices have a significantly greater impact on height for age for children that come from households who are net sellers of these crops. Cereal prices do not appear to be associated with wasting, which is a shorter-term negative health outcome. -

Looking into the performance-based financing black box: Evidence from an impact evaluation in the health sector in Cameroon
(Oxford University Press, 2021-07)Performance-based financing (PBF) is a complex health systems intervention aimed at improving the coverage and quality of care. Several studies have shown a positive impact of PBF on health service coverage, often coupled with improvements in quality, but relatively little is known about the mechanisms driving those results. This article presents results of a randomized impact evaluation in Cameroon designed to isolate the role of specific components of the PBF approach with four study groups: (i) PBF with explicit financial incentives linked to results, (ii) direct financing with additional resources available for health providers not linked to performance, (iii) enhanced supervision and monitoring without additional resources and (iv) a control group. Overall, results indicate that, when compared with the pure control group, PBF in Cameroon led to significant increases in utilization for several services (child and maternal vaccinations, use of modern family planning), but not for others like antenatal care visits and facility-based deliveries. In terms of quality, PBF increased the availability of inputs and equipment, qualified health workers, led to a reduction in formal and informal user fees but did not affect the content of care. However, for many positively impacted outcomes, the differences between the PBF group and the group receiving additional financing not linked to performance are not significant, suggesting that additional funding rather than the explicit incentives might be driving improvements. In contrast, the intervention group offering enhanced supervision, coaching and monitoring without additional funding did not experience significant impacts compared to the control group. -

Disrupted Service Delivery? The Impact of Conflict on Antenatal Care Quality in Kenya
(Frontiers Media, 2021-02-28)African countries facing conflict have higher levels of maternal mortality. Understanding the gaps in the utilization of high-quality maternal health care is essential to improving maternal survival in these states. Few studies have estimated the impact of conflict on the quality of health care. In this study, we estimated the impact of conflict on the quality of health care in Kenya, a country with multiple overlapping conflicts and significant disparities in maternal survival. Our study demonstrates the importance of designing maternal health policy based on the context-specific evidence on the mechanisms through which conflict affects health care. In Kenya, deterioration of equipment and infrastructure does not appear to be the main mechanism through which conflict has affected ANC quality. Further research should focus on better understanding the determinants of the gaps in process quality in conflict-affected settings, including provider motivation, competence, and incentives. -

Exploring Behavioral Competencies for Effective Medical Practice in Nigeria
(Sage Publications, 2020-12-01)Clinical performance varies due to academic, clinical, and behavioral factors. However, in many countries, selection of medical professionals tends to focus on exclusively academic ability and clinical acumen. Appropriate selection processes for medical professionals should consider behavioral factors, which may vary across contexts. This study was conducted to identify behavioral competencies considered relevant for effective medical practice in Nigeria, by medical students and doctors, and compared with other contexts. This study is one of the few to examine the perspectives of medical students and physicians on behavioral competencies for effective medical practice in an African country. We found differences in the perspectives of medical physicians and students, and in the prioritized competencies across countries. Our study illustrates the need for careful consideration in identifying subject matter experts and in generalizing competencies across contexts. Future research in this field in Nigeria should examine effective ways of testing for key behavioral competencies among medical students and for residency programs. Also, investigating the perspectives of medical faculty and administrators on important competencies, and exploring the generalizability of these competencies across cultures in Nigeria should be considered. -

Death Registration in Nigeria: A Systematic Literature Review of its Performance and Challenges
(Taylor and Francis, 2020-09-07)Death registration provides an opportunity for the legal documentation of death of persons. Documentation of deaths has several implications including its use in the recovery of inheritance and insurance benefits. It is also an important input for construction of life tables which are crucial for national planning. However, the registration of deaths is poor in several countries including Nigeria. This paper describes the performance of death registration in Nigeria and factors that may affect its performance. We conducted a systematic literature review of death registration completeness in Nigeria to identify, characterize issues as well as challenges associated with realizing completeness in death registration. Only 13.5% of deaths in Nigeria were registered in 2007 which regressed to 10% in 2017. There was no data reported for Nigeria in the World Health Organization database between 2008 and 2017. The country scored less than 0.1 (out of a maximum of 1) on the Vital Statistics Performance Index. There are multiple institutions with parallel constitutional and legal responsibilities for death registration in Nigeria including the National Population Commission, National Identity Management Commission and Local Government Authorities, which may be contributing to its overall poor performance. -

Opportunities for Improved HIV Prevention and Treatment through Budget Optimization in Eswatini
(PLoS, 2020-07-23)Eswatini achieved a 44% decrease in new HIV infections from 2014 to 2019 through substantial scale-up of testing and treatment. However, it still has one of the highest rates of HIV incidence in the world, with 14 infections per 1,000 adults 15–49 years estimated for 2017. The Government of Eswatini has called for an 85% reduction in new infections by 2023 over 2017 levels. To make further progress towards this target and to achieve maximum health gains, this study aims to model optimized investments of available HIV resources. -

External Validity and Policy Adaptation: From Impact Evaluation to Policy Design
(Published by Oxford University Press on behalf of the World Bank, 2020-07)With the growing number of impact evaluations worldwide, the question of how to apply this evidence in policy making processes has arguably become the main challenge for evidence-based policy making. How can policy makers predict whether a policy will have the same impact in their context as it did elsewhere, and how should this influence the policy’s design and implementation? This paper suggests that failures of external validity (both in transporting and scaling up policy) can be understood as arising from an interaction between a policy’s theory of change and a dimension of the context in which it is being implemented. The paper surveys existing approaches to analyzing external validity, and suggests that there has been more focus on the generalizability of impact evaluation results than on the applicability of evidence to specific contexts. To help fill this gap, the study develops a method of “mechanism mapping” that maps a policy’s theory of change against salient contextual assumptions to identify external validity problems and suggest appropriate policy adaptations. In deciding whether and how to adapt a policy, there is a fundamental informational trade-off between the strength of evidence on the policy from other contexts and the policy maker’s information about the local context. -

Quality of Clinical Assessment and Child Mortality: A Three-Country Cross-Sectional Study
(Oxford University Press, 2020-06)This analysis describes specific gaps in the quality of health care in Central Africa and assesses the association between quality of clinical care and mortality at age 2–59 months. Regionally representative facility and household surveys for the Democratic Republic of the Congo, Cameroon and Central African Republic were collected between 2012 and 2016. These data are novel in linking facilities with households in their catchment area. Compliance with diagnostic and danger sign protocols during sick-child visits was observed by trained assessors. We computed facility- and district-level compliance indicators for patients aged 2–59 months and used multivariate multi-level logistic regression models to estimate the association between clinical assessment quality and mortality at age 2–59 months in the catchment areas of the observed facilities. A total of 13 618 live births were analysed and 1818 sick-child visits were directly observed and used to rate 643 facilities. Eight percent of observed visits complied with 80% of basic diagnostic protocols, and 13% of visits fully adhered to select general danger sign protocols. A 10% greater compliance with diagnostic protocols was associated with a 14.1% (adjusted odds ratio (aOR) 95% CI: 0.025–0.244) reduction in the odds of mortality at age 2–59 months; a 10% greater compliance with select general danger sign protocols was associated with a 15.3% (aOR 95% CI: 0.058–0.237) reduction in the same odds. The results of this article suggest that compliance with recommended clinical protocols remains poor in many settings and improvements in mortality at age 2–59 months could be possible if compliance were improved. -

Responding to Aid Volatility: Government Spending on District Health Care in Zambia 2006-2017
(Taylor and Francis, 2020-02)A corruption event in 2009 led to changes in how donors supported the Zambian health system. Donor funding was withdrawn from the district basket mechanism, originally designed to pool donor and government financing for primary care. The withdrawal of these funds from the pooled financing mechanism raised questions from Government and donors regarding the impact on primary care financing during this period of aid volatility. Financial data were extracted from Government documents and adjusted for inflation. Budget and expenditure for the district level over the period 2006 to 2017 were disaggregated by programmatic area for analysis. Despite the withdrawal of donor funding from the district basket after 2009, funding for primary care allocated to the district level more than doubled from 2006 to 2017. However, human resources accounted for this increase. The operational grant, on the other hand, declined. -

Urbanization and Child Nutritional Outcomes
(Published by Oxford University Press on behalf of the World Bank, 2020-02)The implications of urbanization on child nutritional outcomes are investigated using satellite-based nighttime light intensity data as a marker of urbanization with data from two rounds of the Nigeria Demographic and Health Survey. Nighttime light introduces a gradient of urbanization permitting investigation of the implications of urbanization on child nutritional outcomes along an urbanization continuum. Nightlight is found to significantly predict child nutritional outcomes even after controlling for observable covariates known to influence child nutrition. In all specifications, improvements in child nutrition outcomes onset with relatively low levels of light emissions and continue rapidly as nightlight intensity increases before largely leveling off. These nonlinear relationships highlight the value of nightlight as a population agglomeration indicator relative to traditional binary rural-urban indicators. Consistent with other recent work, patterns of urbanization influence welfare outcomes. At least for Nigeria, a pattern that extends the benefits of urban agglomeration to larger shares of the population would speed improvements to child nutritional outcomes.
