Invitations, Incentives, and Conditions: A Randomized Evaluation of Demand-Side Interventions for Health Screenings
(Elsevier, 2022-03) de Walque, Damien; Chukwuma, Adanna
This randomized controlled trial investigates the impact of four demand-side interventions on health screening for diabetes and hypertension among Armenian adults. The interventions are 1) personalized invitations from a physician, 2) personalized invitations with information about peer screening behavior, 3) personalized invitations with a labeled but unconditional financial incentive, and 4) personal invitations with a conditional financial incentive. Compared with the control group, interventions 1 to 3 led to a significant increase in the screening rate of about 15 percentage points for diabetes and hypertension. The highest impact was measured for intervention 4 leading to a 31.2 percentage point increase in both screenings.
Provider Payment Reforms for Improved Primary Health Care in Romania
(World Bank, Washington, DC, 2021-08) Chukwuma, Adanna; Chen, Dorothee; Gong, Estelle
Romania faces high levels of amenable mortality reflecting, in part, the relatively low utilization rates of high-quality primary health care (PHC), particularly for non-communicable disease (NCD) prevention and treatment. Provider payment mechanisms do not reward the high-quality care provision and may incentivize bypassing of PHC for hospitals, exacerbating challenges presented by physical, financial, and social barriers to accessing essential care. This paper assesses provider payment mechanisms at the PHC level, by examining their design features and implementation arrangements, and exploring their implications for PHC performance in terms of access and quality of care. The authors conclude with policy recommendations to address the constraints identified. To increase the supply of preventative care and case management, the authors recommend that volume thresholds for fee-for-service payments reflect both the number of enrollees and physicians in a practice; laboratory tests required for case management be reduced in scope and their costs be reimbursed; and the law on health care reform be amended to enable the introduction of new payment mechanisms, such as performance-based payments. To expand the scope of PHC and strengthen care coordination with hospitals, periodic reviews by physician commissions should aim to expand the scope of PHC care in line with provisions in other European Union (EU) countries for ambulatory-care sensitive conditions; capitation payments should be adjusted for gender and historical service use to reduce incentive for over-referrals; and payment mechanisms that reward coordination of care, including bundled payments, should be introduced. To establish an enabling environment for provider payment reforms, health information systems should be strengthened by unifying diagnosis coding, establishing quality standards, and ensuring referral module functionality; payment reforms should be informed by extensive consultations with providers at all service delivery levels; and PHC spending should be increased to support higher reimbursement levels for providers and match expenditure levels in high-performing EU health systems.
Armed Conflict and Maternal Health Care Utilization: Evidence from the Boko Haram Insurgency in Nigeria
(Elsevier, 2019-04) Chukwuma, Adanna
Retention in maternal health care is essential to decreasing preventable mortality. By reducing access to care, armed conflicts such as the Boko Haram Insurgency (BHI), contribute to the high maternal mortality rates in Nigeria. While there is a rich literature describing the mechanisms through which conflict affects health care access, studies that estimate the impact of conflict on maternal health care use are sparse and report mixed findings. In this study, we examine the impact of the BHI on maternal care access in Nigeria. We spatially match 52,675 birth records from the Nigeria Demographic and Health Survey (NDHS) with attack locations in the Armed Conflict Location and Event Dataset (ACLED). We define BH conflict area as NDHS clusters with at least five attacks within 3000, 5000 and 10,000 m of BH activity during the study period and employ difference-in-differences methods to examine the effect of the BHI on antenatal care visits, delivery at the health center and delivery by a skilled professional. We find that the BHI reduced the probability of any antenatal care visits, delivery at a health center, and delivery by a skilled health professional. The negative effects of the BHI on maternal health care access extended beyond the Northeastern region, that is the current focus of humanitarian programs. Systematic efforts to identify and address the mechanisms underlying reductions in maternal health care use due to the BHI, and to target the affected populations, are essential to improving maternal health in Nigeria.
Estimating the impact of trained midwives and upgraded health facilities on institutional delivery rates in Nigeria using a quasi-experimental study design
(BMJ Publishing Group Ltd, 2022-05-24) Grépin, Karen Ann; Chukwuma, Adanna; Holmlund, Marcus; Vera-Hernandez, Marcos; Wang, Qiao; Rosa-Dias, Pedro
Studies have shown that demand-side interventions, such as conditional cash transfers and vouchers, can increase the proportion of women giving birth in a health facility in low-income and middle-income countries, but there is limited evidence of the effectiveness of supply-side interventions. We evaluated the impact of the Subsidy Reinvestment and Empowerment Program Maternal and Child Health Project (SURE-PMCH) on rates of institutional delivery and antenatal care. The authors used a differences-in-differences study design that compared changes in rates of institutional delivery and antenatal care in areas that had received additional support through the SURE-PMCH program relative to areas that did not. Data on outcomes were obtained from the 2013 Nigerian Demographic and Health Survey. The authors found that the program significantly increased the proportion of women giving birth in a health facility by approximately 7 percentage points (p=0.069) or approximately 10 percent relative to the baseline after 9 months of implementation. The program, however, did not significantly increase the use of antenatal care. The findings of this study suggest there could be important improvements in institutional delivery rates through greater investment in supply-side interventions.

Chapter 4 reports the analysis results, including the potentialadditional fiscal space and health gains. Finally, chapter 5 presents the conclusionsbased on the findings.
Reforming the Basic Benefits Package in Armenia: Modeling Insights from the Health Interventions Prioritization Tool
(World Bank, Washington, DC, 2021-03-26) Fraser, Nicole; Chukwuma, Adanna; Koshkakaryan, Marianna; Yengibaryan, Lusine; Hou, Xiaohui; Wilkinson, Tommy
Armenia is an upper-middle-income (UMI) country in the South Caucasus region. The Coronavirus (COVID-19) pandemic and a regional crisis have resulted in the real economy's contraction following rapid growth in the past five years. Improving access to high-quality health care is essential for responding to non-communicable diseases (NCDs) and preventing mortality from infectious diseases in Armenia. Armenia is faced with the challenge of achieving Universal Health Coverage (UHC) when funding for health services faces downward pressures due to a donor funding transition, the Coronavirus (COVID-19) pandemic, and regional conflict. This report is part of the World Bank’s technical support toward universal health coverage in Armenia, which includes advisory services and analytics aimed at supporting the government’s efforts to expand access to high-quality health care. The report draws on the Health Interventions prioritization tool to optimize allocations across essential health services in the basic benefits package and estimate the potential impact of these allocations on population health.
Invitations, Incentives, and Conditions: A Randomized Evaluation of Demand-Side Interventions for Health Screenings in Armenia
(World Bank, Washington, DC, 2020-07) De Walque, Damien; Chukwuma, Adanna; Ayivi-Guedehoussou, Nono; Koshkakaryan, Marianna
The study is a randomized controlled trial that investigates the impact of four demand-side interventions on health screening for diabetes and hypertension among Armenian adults ages 35-68 who had not been tested in the last 12 months. The interventions are personal invitations from a physician (intervention group 1), personal invitations with information about peer screening behavior (intervention group 2), a labeled but unconditional cash transfer in the form of a pharmacy voucher (intervention group 3), and a conditional cash transfer in the form of a pharmacy voucher (intervention group 4). Compared with the control group in which only 3.5 percent of participants went for both screenings during the study period, interventions 1 to 3 led to a significant increase in the screening rate of about 15 percentage points among participants. The highest intervention impact was measured among recipients in intervention group 4, whose uptake of screening on both tests increased by 31.2 percentage points. The levels of cost-effectiveness of intervention groups 1, 2, and 4 are similar while for intervention group 3 it is about twice more expensive per additional person screened.
FinHealth Armenia: Reforming Public Financial Management to Improve Health Service Delivery
(World Bank, Washington, DC, 2020-11-02) Gurazada, Srinivas; Chukwuma, Adanna; Jain, Manoj; Tsaturyan, Saro; Khcheyan, Makich
This report aims to assess public financial management (PFM) bottlenecks in health service delivery and identify recommendations for the Ministry of Health (MOH) and its partners in Armenia. This PFM assessment identifies health sector–specific bottlenecks and recommends actions that the MOH and regional (Marz) health authorities can take. Governments have a central role to play in moving countries toward universal health coverage. In low- and middle-income countries, making progress toward universal health coverage involves financing mechanisms that allow for coverage for the formal sector, the poor and the informal sector, to improve the coverage of quality health services. PFM systems, the way public budgets are formed, executed, and monitored interact with health system functions to influence service delivery outcomes. This study builds on a body of research that links improved service delivery outcomes in the health sector to systems for fiscal sustainability, operational efficiency, fiscal transparency, and accountability. The evidence supports the proposition that governance matters for the effective use of public resources in health service delivery.
More Money for Health: Resource Mobilization for Universal Health Coverage in Armenia
(World Bank, Washington, DC, 2021-12-20) Maduko, Franklin; Chukwuma, Adanna; Minasyan, Gevorg; Manookian, Armineh; Saldarriaga Noel, Miguel Angel; Tandon, Ajay
Armenia has made significant gains in population health, but faces challenges in ensuring health care access, due to financial barriers. As mortality caused by infectious diseases has fallen over the past two decades, the prevalence of noncommunicable diseases (NCDs) has increased. The NCD burden can be reduced via public health measures, such as tobacco control exposure, and access to high-quality health care. However, financial barriers to access are a significant challenge.
