Background The forest fires that ravaged parts of Indonesia in 2015 were the most severely polluting of this century but little is known about their effects on health care utilization of the affected population. We estimate their short-term impact on visit rates to primary and hospital care with particular focus on visits for specific smoke-related...

The Indonesian national health insurance agency BPJS Kesehatan, the largest single-payer system in the world, is among the first to combine capitation-based payments with performance-based financing. The Kapitasi Berbasis Komitmen (KBK) scheme for puskesmas (community health centres) was implemented in province capitals between August 2015 and May...

Background In the Netherlands in 2020, COVID-19 deaths were more concentrated among individuals with a lower income. At the same time, COVID-19 was a new cause that also displaced some deaths from other causes, potentially reducing income-related inequality in non-COVID deaths. Our aim is to estimate the impact of the COVID-19 pandemic on the incom...

Measuring performance in healthcare remains a challenge. The use of health outcomes rather than structure and process indicators is considered as the way forward, but outcome-based results risk being biased by selection. Accounting for such selection bias is more difficult in settings with small-sized providers and low chances of resident health im...

(Abstracted from JAMA Network Open 2021;4(11):e2132124) While the contribution of socioeconomic status to disparities in neonatal death and stillbirth has received considerable attention, several key aspects remain understudied. These include the specificity of the association between household income and perinatal outcomes and the contribution of...

Since 2004 the South African government has rolled out free antiretroviral therapy (ART) at public health care facilities nationwide. No prior studies have estimated the impact of the ART rollout on health and survival using a longitudinal household survey with national coverage. We match household member deaths and self-assessed health from a larg...

Introduction Pakistan is a country with high maternal and infant mortality. Several large foreign funded projects were targeted at improving maternal, neonatal and child health. The Norway-Pakistan Partnership Initiative (NPPI) was one of these projects. This study aims to evaluate whether NPPI was successful in improving access and use of skilled...

Importance The association between household income and perinatal health outcomes has been understudied. Examining disparities in perinatal mortality within strata of gestational age and before and after adjusting for birth weight centile can reveal how the income gradient is associated with gestational age, birth weight, and perinatal mortality....

Significance From 1990 to 2018, the Black–White American life expectancy gap fell 48.9% and mortality inequality decreased, although progress stalled after 2012 as life expectancy plateaued. Had improvements continued at the 1990 to 2012 rate, the racial gap in life expectancy would have closed by 2036. Despite decreasing mortality inequality, inco...

Background: In low- and middle-income countries with a high tuberculosis burden, a large fraction of people who are tested for TB do not return to the health facility to collect their test results and initiate treatment, thus putting themselves at increased risk of adverse outcomes. Methods: Our prospective study aimed to identify predictors of ret...

Trends in socioeconomic-related health inequalities is a particularly pertinent topic in South Africa where years of systematic discrimination under apartheid bequeathed a legacy of inequalities in health outcomes. We use three nationally representative datasets to examine trends in income- and race-related inequalities in life expectancy (LE) and...

Some of Adam Wagstsaff’s colleagues and research collaborators submitted short reflections about the different ways Adam made a difference through his amazing research output to health equity and health systems as well as a leader and mentor. The Guest Editors of this Special Issue selected a set of six essays related to dimensions of Adam’s contri...

Background Since the Global Burden of Disease study (GBD) has become more comprehensive, data for hundreds of causes of disease burden, measured using Disability Adjusted Life Years (DALYs), have become increasingly available for almost every part of the world. However, undergoing any systematic comparative analysis of the trends can be challenging...

The Indonesian government has made some ambitious steps to achieve Universal Health Coverage through the newly formed National Health Insurance [Jaminan Kesehatan Nasional (JKN)], establishing a single-payer insurance agency and prospective provider payment mechanism. This study aims to assess the benefit incidence of healthcare funding in the JKN...

Background: Persons with dementia need much care, but what care is used and how the burden of financing is divided between persons with dementia, caregivers, and public programs may differ between countries. Objective: The objective of this study was to compare how health care use and out-of-pocket (OOP) spending associated with dementia differ...

We analyse the trends in inequality in mortality across poverty groups at different ages over the period 1996–2016 in the Netherlands. In addition, we examine whether these trends are related to unequal changes in avoidable mortality, separated by preventable and treatable causes of death. We find that while inequalities in mortality have decreased...

Although there is a large gap between Black and White American life expectancies, the gap fell 48.9%between 1990 and 2018, mainly due to mortality declines among Black Americans. We examine age-specific mortality trends and racial gaps in life expectancy in high- and low-income US areas and with reference to six European countries. Inequalities in...

Does austerity in health care affect health and healthcare outcomes? We examine the intended and unintended effects of the Italian austerity policy Piano di Rientro aimed at containing the cost of the healthcare sector. Using an instrumental variable strategy that exploits the temporal and geographical variation induced by the policy rollout, we fi...

Background Since the Global Burden of Disease study (GBD) has become more comprehensive, data for hundreds of causes of disease burden, measured using Disability Adjusted Life Years (DALYs), have become increasingly available for almost every part of the world. However, undergoing any systematic comparative analysis of the trends can be challenging...

We study horizontal inequity in home care use in the Netherlands, where a social insurance scheme aims to allocate long‐term care according to care needs. Whether the system reaches its goal depends not only on whether eligible individuals have equal access to care but also on whether entitlements for care reflect needs, irrespective of socioeconom...

Encouraging and helping elderly to postpone a nursing home admission appears to be a win-win that keeps long-term care spending in check and is in line with the target population’s preferences, but there is little evidence about its effects. We study the causal impact of nursing home admission eligibility using Dutch administrative data and exploit...

Regulators may be hesitant to permit price competition in healthcare markets because of its potential to damage quality. We assess whether this fear is well founded by examining a reform that permitted Dutch health insurers to freely negotiate prices with hospitals. Unlike previous research on hospital competition that has relied on quality indicat...

The Netherlands is one of the few countries that offer generous universal public coverage of long‐term care (LTC). Does this ensure that the Dutch elderly with similar care needs receive similar LTC, irrespective of their income? In contrast with previous studies of inequity in care use that relied on a statistically derived variable of needs, our...

Unexpected negative health shocks of a parent may reduce adult children's labour supply via informal caregiving and stress-induced mental health problems. We link administrative data on labour market outcomes, hospitalisations and family relations for the full Dutch working age population for the years 1999-2008 to evaluate the effect of an unexpec...

The Great Recession in Europe sparked concerns that the crisis would lead to increased income related health inequalities (IRHI). Did this come to pass, and what role, if any, did government transfers play in the evolution of these inequalities? Motivated by these questions, this paper seeks to (i) study the evolution of IRHI during the crisis, and...

In 2008, the Rural Health Project (Health XI) was initiated in 40 Chinese counties to pilot interventions aimed at improving local health systems. Performance targets were pre‐specified (results‐based), and project counties were allowed to tailor their interventions (bottom‐up) in recognition of the substantial regional variations. Using household...

In spite of the enormous economic progress and development witnessed in Indonesia in the last few decades, still more than 30% of Indonesian children under the age of five suffer from stunting, or low height for age. This concern is exacerbated by the fact that stunting remains more concentrated among the poorer households, leading to further inter...

Background TB persists despite being relatively easy to detect and cure because the journey from the onset of symptoms to cure involves a series of steps, with patients being lost to follow-up at each stage and delays occurring among patients not lost to follow-up. One cause of drop-off and delay occurs when patients delay or avoid returning to cli...

There have been steep falls in rates of child stunting in much of Sub-Saharan Africa (SSA). Using Demographic and Health Survey data, we document significant reductions in stunting in seven SSA countries in the period 2005-2014. For each country, we distinguish potential determinants that move in a direction consistent with having contributed to th...

Background The frequent occurrence of medicine stockouts represents a significant obstacle to tuberculosis control in South Africa. Stockouts can lead to treatment alterations or interruptions, which can impact treatment outcomes. This study investigates the determinants and effects of TB drug stockouts and whether poorer districts are disproportio...

Informal caregiving is a potentially attractive alternative to formal care but may entail health costs for the caregiver. We examine the mental and physical health impact of providing informal care and disentangle the caregiving effect – the effect of caring for someone in need – from the family effect – the effect of caring about someone in need....

Evidence on households’ ability to smooth consumption over health shocks is mostly obtained from environments where there is little or no formal insurance of either medical expenses or sickness-related earnings losses. To establish whether households remain economically vulnerable to illness after the introduction of universal health coverage (UHC)...

Objective: Informal care, the provision of unpaid care to dependent friends or family members, is often associated with physical and mental health effects. As some individuals are more likely to provide caregiving tasks than others, estimating the causal impact of caregiving is difficult. This systematic literature review provides an overview of a...

Traditionally, threshold levels of cost‐effectiveness have been derived from willingness‐to‐pay studies, indicating the consumption value of health (v‐thresholds). However, it has been argued that v‐thresholds need to be supplemented by so‐called k‐thresholds, which are based on the marginal returns to health care. The objective of this research is...

In spite of the wide disparities in wealth and in objective health measures like mortality, observed inequality by wealth in self-reported health appears to be nearly nonexistent in low- to middle-income settings. To determine the extent to which this is driven by reporting tendencies, we use anchoring vignettes to test and correct for reporting he...

Post-apartheid South Africa has seen an unprecedented rise and fall of mortality in less than two decades as a result of the HIV/AIDS epidemic and the subsequent rollout of free antiretroviral therapy (ART). Since the incidence of both was not equal for rich and poor, it is likely to also have affected disparities in health and survival chances by...

Interventions aiming to simultaneously improve financial protection and quality of care may provide an important avenue towards universal health coverage. We estimate the effects of the introduction of the Kwara State Health Insurance program in Nigeria on not only the insured but also the uninsured. A subsidized voluntary low cost health insurance...

Inaccurate longevity expectations can result in suboptimal lifecycle planning with negative consequences for wellbeing in old age. We evaluate the accuracy of expectations by comparing the subjective probability of living to 75 reported in the Health and Retirement Study with survival to that age. Outcomes are positively correlated with the subject...

Health is well known to show a clear gradient by occupation. Although it may appear evident that occupation can affect health, there are multiple possible sources of selection that can generate a strong association, other than simply a causal effect of occupation on health. We link job characteristics to German panel data spanning 29 years to chara...

Although end-of-life medical spending is often viewed as a major component of aggregate medical expenditure, accurate measures of this type of medical spending are scarce. We used detailed health care data for the period 2009-11 from Denmark, England, France, Germany, Japan, the Netherlands, Taiwan, the United States, and the Canadian province of Q...

For many years, Pakistan has had a wide network of Basic Health Units spread across the country, but their utilization by the population in rural and peri-urban areas has remained low. As of 2004, in an attempt to improve the utilization and performance of these public primary healthcare facilities, the government has gradually started contracting-...

Informal care may substitute for formal long-term care that is often publicly funded or subsidized. The costs of informal caregiving are borne by the caregiver and may consist of worse health outcomes and, if the caregiver has not retired, worse labor market outcomes. We estimate the impact of providing informal care to one's partner on the caregiv...

Little is known about how health disparities by income change during times of economic crisis. We apply a decomposition method to unravel the contributions of income growth, income inequality and differential income mobility across socio-demographic groups to changes in health disparities by income in Spain using longitudinal data from the Survey o...

The Netherlands is among the top spenders on health in the OECD. We document the life-cycle profile, concentration and persistence of this expenditure using claims data covering both curative and long-term care expenses for the full Dutch population. Spending on health care is strongly concentrated: the 1 per cent of individuals with the highest le...

In countries with a public long-term care (LTC) insurance scheme administered by multiple non-competing insurers, these insurers typically lack incentives for purchasing cost-effective LTC because they are not at risk for LTC expenses. Plans to introduce these incentives by allowing competition among risk bearing LTC insurers are likely to jeopardi...

Around the world, and in spite of their higher life expectancy, women tend to report worse health than men until old age. Explanations for this gender gap in self-perceived health may be different in China than in other countries due to the traditional phenomenon of son preference. We examine several possible reasons for the gap using the Chinese S...

The use of long-term care (LTC) is changing rapidly. In the Netherlands, rates of institutional LTC use are falling, whereas homecare use is growing. Are these changes attributable to declining disability rates, or has LTC use given disability changed? And have institutionalization rates fallen regardless of disability level, or has LTC use become...

We estimate the impact on out-of-pocket (OOP) medical expenditure of a major reform in Thailand that greatly extended health insurance coverage to achieve universality while implementing supply-side measures intended to deliver cost-effective care from an increased, but modest, public health budget. Difference-in-differences comparison of groups to...

We examine economic vulnerability to illness when, as for informal sector workers in Thailand, there is universal coverage for health care but earnings losses are uninsured. Even with comprehensive health care entitlement, severe illness that strikes an initially healthy worker is found to raise out-of-pocket medical expenses by around two thirds a...

Biased longevity expectations will lead to suboptimal decisions regarding saving, retirement, annuitization and health, with consequences for wellbeing in old age. Systematic differences in the accuracy of longevity expectations may partly explain heterogeneity in economic behaviour by education and cognitive functioning. Analysis of eight waves of...

Several governments in low- and middle-income countries have adopted performance-based financing to increase health care use and improve the quality of health services. We evaluated the effects of performance-based financing in the central African nation of Burundi by exploiting the staggered rollout of this financing across provinces during 2006-1...

Africa's progress towards the health related Millennium Development Goals remains limited. This can be partly explained by inadequate performance of health care providers. It is therefore critical to incentivize this performance. Payment methods that reward performance related to quantity and quality, called performance based financing (PBF), have...

The introduction of the New Cooperative Medical Scheme (NCMS) in rural China has been the most rapid and dramatic extension of health insurance coverage in the developing world in this millennium. The literature to date has mainly used the uneven rollout of NCMS across counties as a way of identifying its effects on access to care and financial pro...

Objective: To evaluate the effect of vouchers for maternity care in public health-care facilities on the utilization of maternal health-care services in Cambodia. Methods: The study involved data from the 2010 Cambodian Demographic and Health Survey, which covered births between 2005 and 2010. The effect of voucher schemes, first implemented in...

Although it seems evident that occupation affects health, effect estimates are scarce. We use a job characteristics matrix linked to German longitudinal data spanning 26 years to characterise occupations by their physical and psychosocial burdens. Employing a dynamic model to control for factors that simultaneously affect health and selection into...

Health is distributed unequally by occupation. Workers on a lower rung of the occupational ladder report worse health, have a higher probability of disability and die earlier than workers higher up the occupational hierarchy. Using a theoretical framework that unveils some of the potential mechanisms underlying these disparities, three core insight...

Several studies have documented the now fairly stylized fact that health inequalities by income differ across the age distribution: in cross-sections the health gap between rich and poor tends to widen until about age 50 and then declines at higher ages. It has been suggested that selective mortality and institutionalization could be important fact...

In recent decades, China has experienced double-digit economic growth rates and rising inequality. This paper implements a new decomposition approach using the China Health and Nutrition Survey (1991-2006) to examine the extent to which changes in level and distribution of incomes and in income mobility are related to health disparities between ric...

An equitable distribution of healthcare use, distributed according to people's needs instead of ability to pay, is an important goal featuring on many health policy agendas worldwide. However, relatively little is known about the extent to which this principle is violated across socio-economic groups in Sub-Saharan Africa (SSA). We examine cross-co...

Public providers have no financial incentive to respect their legal obligation to exempt the poor from user fees. Health Equity Funds (HEFs) aim to make exemptions effective by giving NGOs responsibility for assessing eligibility and compensating providers for lost revenue. We use the geographic spread of HEFs over time in Cambodia to identify thei...

We use matching combined with difference-in-differences to identify the causal effects of sudden illness, represented by acute hospitalizations, on employment and income up to six years after the health shock using linked Dutch hospital and tax register data. An acute hospital admission lowers the employment probability by seven percentage points a...

Performance-based financing (PBF) has attracted considerable interest from governments and aid agencies in low-income countries as a means to increase productivity and quality of health-care providers. In Africa alone, more than 35 countries are in the process of introducing payment methods that reward performance. The Burundi Government has gradua...

We estimate the impact on health care utilization and out-of-pocket (OOP) expenditures of a major reform in Thailand that extended health insurance to one-quarter of the population to achieve universal coverage while keeping health spending below 4% of GDP. Identification is through comparison of changes in outcomes of groups to whom coverage was e...

When public long-term care (LTC) insurance is provided by insurers, they typically lack incentives for purchasing cost-effective LTC. Providing insurers with appropriate incentives for efficiency without jeopardizing access for high-risk individuals requires, among other things, an adequate system of risk adjustment. While risk adjustment is now wi...

International differences in long-term care (LTC) use are well documented, but not well understood. Using comparable data from two countries with universal public LTC insurance, the Netherlands and Germany, we examine how institutional differences relate to differences in the choice for informal and formal LTC. Although the overall LTC utilization...

While it seems evident that occupations affect health, effect estimates are scarce. We use a job characteristics matrix in order to characterize occupations by their physical and psychosocial burden in German panel data spanning 26 years. Employing a dynamic model to control for factors that simultaneously affect health and selection into occupatio...

We examine the relationship between income and health with the purpose of establishing the extent to which the distribution of health in a population contributes to income inequality and is itself a product of that inequality. The evidence supports a significant and substantial impact of ill-health on income mainly operating through employment, alt...

This paper investigates the relationship between occupation and health, and confirms that – also in the Netherlands in recent years – workers on a lower step of the occupational ladder on average report worse health, have a higher probability of disability and die earlier than workers in higher occupations. We sketch a theoretical framework to bett...

Explanations of growth in health expenditures have restricted attention to the mean. We explain change throughout the distribution of expenditures, providing insight into how expenditure growth and its explanation differ along the distribution. We analyse Dutch data on actual health expenditures linked to hospital discharge and mortality registers....

This study uses data from the 1994 National Population Health Survey and applies the methods developed by Wagstaff and van Doorslaer (1994, measuring inequalities in health in the presence of multiple-category morbidity indicators. Health Economics 3, 281–291) to measure the degree of income-related inequality in self-reported health in Canada by m...

We propose a method of measuring and decomposing inequity in health care utilisation that allows for heterogeneity in the use-need relationship. This makes explicit inequity that derives from unequal treatment response to variation in need, as well as that due to differential effects of non-need determinants. Under plausible conditions concerning h...

The introduction of the New Cooperative Medical Scheme in rural China is one of the largest health care reforms in the developing world since the millennium. The literature to date has mainly used the uneven rollout of NCMS across counties as a way of identifying its effects on access to care and financial protection. This study exploits the cross-...
