Realizing the right to health in Brazil's Unified Health System through the lens of breast and cervical cancer.

BACKGROUND: Health is recognized as a fundamental right in Brazil's constitution. In the absence of a clearly defined benefit packages of healthcare services that are financed under the Unified Health System (Sistema Único de Saúde, SUS), courts have become important in adjudicating coverage decisions. Empirical assessments of equity and the right to health tend to focus on simple measures of access. However, these empirical perspectives belie the significant inequalities and rights violations that arise in the case of more complex health needs such as cancer. To shed light on these issues, this paper focuses on the care pathways for breast and cervical cancer and explores access and quality issues that arise at different points along the care pathway with implications for the realization of the right to health in Brazil. METHOD: A mixed method approach is used. The analysis is primarily based on a quantitative analysis of national representative administrative data principally from the cervical and breast cancer information systems and the hospital cancer registry. To gain more insights into the organization of cancer care, qualitative data was collected from the state of Bahia, through document analysis, direct observation, roundtable discussions with health workers (HWs), and structured interviews with health care administrators. RESULTS: The paper reveals that the volume of completed screening exams is well below the estimated need, and a tendency toward lower breast cancer screening rates in poorer states and for women in the lowest income brackets. Only 26% of breast cancer cases and 29% of cervical cancer cases are diagnosed at an early stage (stage 0 or I), thereby reducing the survival prospects of patients. Waiting times between confirmed diagnosis and treatment are long, despite new legislation that guarantees a maximum of 60 days. The waiting times are significantly longer for patients that follow the recommended patient pathways, and who are diagnosed outside the hospital. CONCLUSION: The study reveals that there are large variations between states and patients, where the poorest states and patients fare worse on key indicators. More broadly, the paper shows the importance of collecting data both on patient characteristics and health system performance and carry out detailed health system analysis for exposing, empirically, rights violations and for identifying how they can be addressed.

Expanding the primary health care workforce through contracting with nongovernmental entities: the cases of Bahia and Rio de Janeiro.

BACKGROUND: Brazil has experienced difficulties in attracting health professionals (especially doctors and nurses) to practice at the primary health care (PHC) level and in rural and remote areas. This study presents two case studies, each a current initiative in contracting for primary health services in Brazil: one for the state of Bahia and the other for the city of Rio de Janeiro. The two models differ considerably in context, needs, modalities, and outcomes. This article does not attempt to evaluate the initiatives but to identify their strengths and weaknesses. METHODS: Analysis was based on indicators produced by the Brazilian health care information systems, a review of literature and other documentation, and key informant interviews. RESULTS: In the case of Bahia, the state and municipalities decided to create a State Foundation, a new institutional public entity acting under private law that centralizes the hiring of health professionals in order to offer stable positions with career plans and mobility within the state. Results have been mixed as a lower than expected municipal involvement resulted in relatively high administrative costs and consequent default on municipal financial contributions. In the case of Rio de Janeiro, the municipality opted to contract not-for-profit Social Organizations as it made a push to expand access to primary health care in the city. The approach has been successful in expanding coverage, but evidence on cost and performance is weak. CONCLUSIONS: Both cases highlight that improvements in cost and performance data will be critical for meaningful comparative evaluation of delivery arrangements in primary care. Despite the different institutional and implementation arrangements of each model, which make comparison difficult, the analysis provides important lessons for contracting out health professionals for PHC within Brazil and elsewhere.

Integrated care delivery and health care seeking by chronically-ill patients - a case-control study of rural Henan province, China.

OBJECTIVE: This study examined the impact of an Integrated Care Delivery intervention on health care seeking and outcomes for chronically-ill patients in Henan province, China. METHODS: A case-control study was carried out in six health care organizations from two counties in Henan province, China. 371 patients aged 50 years or over with hypertension or diabetes who visited either community health centers or hospitals in the Intervention or Control Counties were systematically selected and surveyed on health care seeking behavior, quality of care, and pathway of care for their major chronic condition. Bivariate analyses were performed to compare quality and value of care indicators between patients from the Intervention and Control Counties. Multivariate analyses were used to confirm these associations after controlling for patients' demographic and health characteristics. RESULTS: Patients in both the Intervention and Control Counties chose their current health care providers primarily out of concern for quality of care (provider expertise and adequate medical equipment) and patient-centered care. Compared with the patients from the Control County, those from the Intervention County performed significantly better on almost all the quality and value of care indicators even after controlling for patients' demographic and health characteristics. Significant associations between types of health care facilities and quality as well as value of care were also observed. CONCLUSION: The study showed that the Integrated Care Delivery Model was critical in guiding patients' health care seeking behavior and associated with improved accessibility, continuity, coordination and comprehensiveness of care, as well as reducing health inequities and mitigating disparities for older patients with chronic conditions.

Community health centers and primary care access and quality for chronically-ill patients - a case-comparison study of urban Guangdong Province, China.

OBJECTIVE: Reform of the health care system in urban areas of China has prompted concerns about the utilization of Community Health Centers (CHC). This study examined which of the dominant primary care delivery models, i.e., the public CHC model, the 'gate-keeper' CHC model, or the hospital-owned CHC models, was most effective in enhancing access to and quality of care for patients with chronic illness. METHODS: The case-comparison design was used to study nine health care organizations in Guangzhou, Dongguan, and Shenzhen cities within Guangdong province, China. 560 patients aged 50 or over with hypertension or diabetes who visited either CHCs or hospitals in these three cities were surveyed by using face-to-face interviews. Bivariate analyses were performed to compare quality and value of care indicators among subjects from the three cities. Multivariate analyses were used to assess the association between type of primary care delivery and quality as well as value of chronic care after controlling for patients' demographic and health status characteristics. RESULTS: Patients from all three cities chose their current health care providers primarily out of concern for quality of care (both provider expertise and adequate medical equipment), patient-centered care, and insurance plan requirement. Compared with patients from Guangzhou, those from Dongguan performed significantly better on most quality and value of care indicators. Most of these indicators remained significantly better even after controlling for patients' demographic and health status characteristics. The Shenzhen model (hospital-owned and -managed CHC) was generally effective in enhancing accessibility and continuity. However, coordination suffered due to seemingly duplicating primary care outpatients at the hospital setting. Significant associations between types of health care facilities and quality of care were also observed such that patients from CHCs were more likely to be satisfied with traveling time and follow-up care by their providers. CONCLUSION: The study suggested that the Dongguan model (based on insurance mandate and using family practice physicians as 'gate-keepers') seemed to work best in terms of improving access and quality for patients with chronic conditions. The study suggested adequately funded and well-organized primary care system can play a gatekeeping role and has the potential to provide a reasonable level of care to patients.

The impact of community-based health insurance on utilization and out-of-pocket expenditures in Lao People's Democratic Republic.

Community-based health insurance in Lao People's Democratic Republic targets the informal workforce. Estimates of the program's impact on utilization and out-of-pocket expenditures (OOPs) were obtained using a case-comparison study of 3000 households (14 804 individuals) in urban and semi-urban areas. We used propensity score matching to control for bias on observables and to account for heterogeneity. We check the sensitivity of the results using a weighted regression combined with propensity score matching, which leads to doubly robust treatment effect estimates. The results are robust across the two approaches and show that the insured have significantly higher utilization, lower OOPs and lower incidence of catastrophic expenditures, and are less likely to employ coping mechanisms. However, coverage of the scheme is extremely low, indicating negligible population level impact. Furthermore, the results show that the scheme provides greater protection to the better off than to the poor: the poor are less likely to enrol, and among the poor who are enrolled, there has been no significant impact on utilization of outpatient services, total OOPs or catastrophic expenditures. We discuss the policy implications in the context of the international debate regarding the prospects for the role of community-based health insurance in national financing strategies.

Evasion of "mandatory" social health insurance for the formal sector: evidence from Lao PDR.

BACKGROUND: In the last decade, almost every low- or middle-income country in the world has expressed support for universal health coverage (UHC). While at the beginning of the UHC movement, country strategies focused on increasing access to the formal sector as the first step of UHC, there is now consensus that countries should cover the entire population, with particular attention to covering the poor. However, it is often assumed that mandatory schemes will automatically cover their target populations, and consequently little is known about why firms comply or do not comply with enrolment requirements. Using the experience of Lao PDR, where the enrolment rate in the mandatory social security scheme is low and the capacity for regulation is weak, we conducted this study to better understand the determinants of enrolment of private sector firms in mandatory social security. METHODS: We used a cross-sectional case-comparison design, surveying 130 firms. We applied a structured questionnaire to explore determinants of enrolment, specifically looking at firm characteristics (e.g., industry category, ownership); sociodemographic characteristics of company heads; firms' risk perceptions; details of employment contracts; employee benefits; and exposure to social security. Closed ended questions were analysed quantitatively, while content analysis was applied to open-ended questions. Logistic regression was used to examine the determinants of enrolment. RESULTS: Smaller privately owned firms in the services industry were the least likely to enrol in social security, while firms in the trade industry were more likely to enrol than firms in manufacturing, construction, or services. The main reason for not enrolling was that firms offered a better package of benefits to their employees, although further investigation of company benefits showed that this was not the case in practice. Additional reasons for non-compliance were lack of knowledge and poor quality of care at government hospitals. CONCLUSIONS: The study contributes to the dialogue on how best to increase coverage in the formal sector, which is an important element of achieving UHC. It also provides much needed information about the motivation of private sector firms to comply with mandatory schemes.

Are health shocks different? Evidence from a multishock survey in Laos.

Using primary data from Laos, we compare a broad range of different types of shocks in terms of their incidence, distribution between the poor and the better off, idiosyncrasy, costs, coping responses, and self-reported impacts on well-being. Health shocks are more common than most other shocks, more concentrated among the poor, more idiosyncratic, more costly, trigger more coping strategies, and highly likely to lead to a cut in consumption. Household members experiencing a health shock lost, on average, 0.6 point on a five-point health scale; the wealthier are better able to limit the health impacts of a health shock.

Human resource challenges in health systems: evidence from ten African countries.

Sub-Saharan Africa has fewer medical workers per capita than any region of the world, and that shortage has been highlighted consistently as a critical constraint to improving health outcomes in the region. This paper draws on newly available, systematic, comparable data from ten countries in the region to explore the dimensions of this shortage. We find wide variation in human resources performance metrics, both within and across countries. Many facilities are barely staffed, and effective staffing levels fall further when adjusted for health worker absences. However, caseloads-while also varying widely within and across countries-are also low in many settings, suggesting that even within countries, deployment rather than shortages, together with barriers to demand, may be the principal challenges. Beyond raw numbers, we observe significant proportions of health workers with very low levels of clinical knowledge on standard maternal and child health conditions. This work demonstrates that countries may need to invest broadly in health workforce deployment, improvements in capacity and performance of the health workforce, and on addressing demand constraints, rather than focusing narrowly on increases in staffing numbers.

Changes in pregnancy and childbirth practices in remote areas in Lao PDR within two generations of women: implications for maternity services.

This paper sheds light on the inter-generational changes in pregnancy and childbirth practices in remote areas of Lao PDR over a period of 30 years. The study consisted of focus group discussions with pregnant women aged 14-30, mothers and fathers of small children, and older women aged 40+ in six rural communities in two districts. Childbirth practices were gradually evolving and changing - most dramatically illustrated by the transition from forest-based to home-based delivery, and a few health facility-based deliveries when complications occurred. Today's generation of women aged 40+ did not recommend all the practices of their mothers, but saw the need to adapt due to the social and medical risks they had experienced, especially high rates of neonatal death. Their daughters are doing the same. The increase in home-based deliveries should be regarded as significant progress in this setting in rural Laos. Understanding how young women interpret their options and incorporating that knowledge and the experience of successful local outreach programmes into health system policy and practice for maternity care, e.g. by strengthening the skills of community-based health workers, could contribute to improving maternal and neonatal survival and reducing health inequalities.

Achieving universal health coverage through voluntary insurance: what can we learn from the experience of Lao PDR?

BACKGROUND: The Government of Lao Peoples' Democratic Republic (Lao PDR) has embarked on a path to achieve universal health coverage (UHC) through implementation of four risk-protection schemes. One of these schemes is community-based health insurance (CBHI) - a voluntary scheme that targets roughly half the population. However, after 12 years of implementation, coverage through CBHI remains very low. Increasing coverage of the scheme would require expansion to households in both villages where CBHI is currently operating, and new geographic areas. In this study we explore the prospects of both types of expansion by examining household and district level data. METHODS: Using a household survey based on a case-comparison design of 3000 households, we examine the determinants of enrolment at the household level in areas where the scheme is currently operating. We model the determinants of enrolment using a probit model and predicted probabilities. Findings from focus group discussions are used to explain the quantitative findings. To examine the prospects for geographic scale-up, we use secondary data to compare characteristics of districts with and without insurance, using a combination of univariate and multivariate analyses. The multivariate analysis is a probit model, which models the factors associated with roll-out of CBHI to the districts. RESULTS: The household findings show that enrolment is concentrated among the better off and that adverse selection is present in the scheme. The district level findings show that to date, the scheme has been implemented in the most affluent areas, in closest proximity to the district hospitals, and in areas where quality of care is relatively good. CONCLUSIONS: The household-level findings indicate that the scheme suffers from poor risk-pooling, which threatens financial sustainability. The district-level findings call into question whether or not the Government of Laos can successfully expand to more remote, less affluent districts, with lower population density. We discuss the policy implications of the findings and specifically address whether CBHI can serve as a foundation for a national scheme, while exploring alternative approaches to reaching the informal sector in Laos and other countries attempting to achieve UHC.

Coping with uncertainty during healthcare-seeking in Lao PDR.

BACKGROUND: Uncertainty is regarded as a central dimension in the experience of illness and in the processes of alleviating it. Few studies from resource-poor settings have investigated this and how it interacts with other factors. This study aims to shed light on how healthcare-seeking develops in the context of multiple medical alternatives and to understand what bearing uncertainty has on this process. METHODS: The study was conducted in six purposively selected rural communities in Lao PDR. In each community, two focus group discussions were held: first with mothers and then with fathers of children younger than five years old. Eleven in-depth interviews with caregivers of severely sick children were conducted. Subsequently, traditional healers, drug vendors, community health workers, nurses and medical doctors were recruited for interviews or group discussions. The data were transcribed and key themes and similarities were identified. Additional readings were conducted to better understand the interactions of factors during which uncertainty was identified as one of several factors mentioned during interviews and focus group discussions. RESULTS: Care-seekers expressed a strong preference for initially seeking local providers. Subsequently, multiple providers were consulted to increase the chances of recovery. This resulted in patients leaving the health facilities before recovery and in ending the recommended treatment regime prematurely. These healthcare-seeking decisions reflect the social significance of being a responsible caregiver and of showing respect for household norms. In general, healthcare-seeking was shrouded in uncertainty when it came to selecting the right provider, the likelihood of finding the real cause of the illness, spending savings on treatments and ultimately the likelihood of recovery. CONCLUSIONS: Care-seekers' initial strong preference for local providers irrespective of the providers' legitimacy indicates the need for a robust primary healthcare system. Care-seekers' subsequent consultations must be understood in the light of their uncertainty regarding the skills of the available providers. The social connotations of seeking healthcare including the vulnerability of poor households in public health facilities were taken into account to only a limited extent by health workers. Health workers should have greater awareness of the social and cultural aspects of seeking care.

Human resources for health in southeast Asia: shortages, distributional challenges, and international trade in health services.

In this paper, we address the issues of shortage and maldistribution of health personnel in southeast Asia in the context of the international trade in health services. Although there is no shortage of health workers in the region overall, when analysed separately, five low-income countries have some deficit. All countries in southeast Asia face problems of maldistribution of health workers, and rural areas are often understaffed. Despite a high capacity for medical and nursing training in both public and private facilities, there is weak coordination between production of health workers and capacity for employment. Regional experiences and policy responses to address these challenges can be used to inform future policy in the region and elsewhere. A distinctive feature of southeast Asia is its engagement in international trade in health services. Singapore and Malaysia import health workers to meet domestic demand and to provide services to international patients. Thailand attracts many foreign patients for health services. This situation has resulted in the so-called brain drain of highly specialised staff from public medical schools to the private hospitals. The Philippines and Indonesia are the main exporters of doctors and nurses in the region. Agreements about mutual recognition of professional qualifications for three groups of health workers under the Association of Southeast Asian Nations Framework Agreement on Services could result in increased movement within the region in the future. To ensure that vital human resources for health are available to meet the needs of the populations that they serve, migration management and retention strategies need to be integrated into ongoing efforts to strengthen health systems in southeast Asia. There is also a need for improved dialogue between the health and trade sectors on how to balance economic opportunities associated with trade in health services with domestic health needs and equity issues.

Building on community outreach for childhood vaccination to deliver maternal and child health services in Laos: a feasibility assessment.

Outreach services for vaccination present a useful vehicle to deliver maternal and child health (MCH) care to hard-to-reach women and children. In Laos, uptake of MCH services inversely correlates with distance from a health facility; hence, the concurrent delivery of MCH services during community vaccination outreach has been promoted. Here we assess factors affecting delivery of MCH services during vaccination outreach in six districts of three provinces. We conducted 58 in-depth interviews with representatives of district and provincial health offices, health centre staff and village health volunteers. Vaccination outreach sessions by health centre staff were observed in eight villages, and 12 focus group discussions were held with 120 mothers on their perceptions of these sessions. The regularity and frequency of outreach sessions and the number of integrated vaccination/MCH services varied widely between sites. Availability of external financial and technical support was the major determinant of optimal delivery of integrated services, with implications for future policy. To enable concurrent delivery of a range of MCH services during vaccination outreach, the number of these services should gradually be increased in tandem with additional financial and technical support. At the same time, ways need to be found to ensure remote villages are reached and coverage of children and women receiving services increased, to reduce inequity.

Shaping healthcare-seeking processes during fatal illness in resource-poor settings. A study in Lao PDR.

BACKGROUND: There are profound social meanings attached to bearing children that affect the experience of losing a child, which is akin to the loss of a mother in the household. The objective of this study is to comprehend the broader processes that shape household healthcare-seeking during fatal illness episodes or reproductive health emergencies in resource-poor communities. METHODS: The study was conducted in six purposively selected poor, rural communities in Lao PDR, located in two districts that represent communities with different access to health facilities and contain diverse ethnic groups. Households having experienced fatal cases were first identified in focus group discussions with community members, which lead to the identification of 26 deaths in eleven households through caregiver and spouse interviews. The interviews used an open-ended anthropological approach and followed a three-delay framework. Interpretive description was used in the data analysis. RESULTS: The healthcare-seeking behavior reported by caregivers revealed a broad range of providers, reflecting the mix of public, private, informal and traditional health services in Lao PDR. Most caregivers had experienced multiple constraints in healthcare-seeking prior to death. Decisions regarding care-seeking were characterized as social rather than individual actions. They were constrained by medical costs, low expectations of recovery and worries about normative expectations from healthcare workers on how patients and caregivers should behave at health facilities to qualify for treatment. Caregivers raised the difficulties in determining the severity of the state of the child/mother. Delays in reaching care related to lack of physical access and to risks associated with taking a sick family member out of the local community. Delays in receiving care were affected by the perceived low quality of care provided at the health facilities. CONCLUSIONS: Care-seeking is influenced by family- and community-based relations, which are integrated parts of people's everyday life. The medical and normative responses from health providers affect the behavior of care-seekers. An anthropological approach to capture the experience of caregivers in relation to deciding, seeking and reaching care reveals the complexity and socio-cultural context surrounding maternal and child mortality and has implications for how future mortality data should be developed and interpreted.

Child Health Outcome Inequalities in Low and Middle Income Countries.

Prior to the Sustainable Development Goals (SDG) era, considerable progress was made toward the Millennium Development Goals (MDGs) health indicators. Despite these achievements, many countries failed to meet the MDG target levels, between-country inequalities in health outcomes did not improve, and many countries making progress in average indicator levels did so while at the same time seeing increasing within-country inequalities. We build on the existing literature documenting levels and trends in health inequalities by expanding the number of data-points under focus, and we contribute to this literature by analyzing the extent to which inequalities in child health outcomes are related to socioeconomic inequalities, and to aggregate income growth. The objective of this paper is to examine long-run trends in average population levels and within-country inequalities for two child health outcomes-the under-five mortality rate (U5MR) and stunting-in 102 countries across 6 regions. We find that only about a third of countries in our sample managed to both reduce U5MR levels and inequalities, and only a quarter did so for stunting. The fact that inequality in service coverage seems to follow a more favorable trend than inequality in health outcomes suggests that policies aiming to reduce health inequities should not only foster more equitable service coverage but also focus on the social determinants of health. Moreover, there is no strong correlation between changes in health inequalities and income growth, suggesting that income generating development policies alone will typically not suffice to improve health outcomes and reduce health inequalities.

In Appreciation of Adam: Reflections from Friends and Colleagues.

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 contributions.The first contribution highlights his role early on in his career, prior to joining the World Bank, in defining and expanding an important field of research on equity in health ("Adam and Equity," by Eddy van Doorslaer and Owen O'Donnell). The second contribution focuses on Adam's early work on equity and health within the World Bank and his leadership on important initiatives that have had impact far beyond the World Bank ("Adam and Health Equity at the World Bank," by Davidson Gwatkin and Abdo Yazbeck). The next contribution focuses on Adam's deep dive into providing support, through research, for country-specific programs and reforms, with a special focus on some countries in East Asia ("Adam and Country Health System Research," by Magnus Lindelow, Caryn Bredenkamp, Winnie Yip, and Sarah Bales). The next contribution highlights Adam's many ways of contributing to the International Health Economics Association, from the impressive technical contributions to leadership and organizational reform ("Adam and iHEA," by Diane McIntyre). The next to last contribution focuses on Adam's long-term leadership in the research group at the World Bank and the long-lasting influence on integrating the research produced into World Bank operations and creating an environment that rewarded producing evidence for action ("Adam the Research Manager," by Deon Filmer and Damien de Walque). The last contribution pulls on the thread found in many of the earlier ones, mentorship with honesty, directness, caring, commitment, and equity ("Adam the Mentor," by Agnes Couffinhal, Caryn Bredenkamp, and Reem Hafez).

Analysis of clinical knowledge, absenteeism and availability of resources for maternal and child health: a cross-sectional quality of care study in 10 African countries.

OBJECTIVE: Assess the quality of healthcare across African countries based on health providers' clinical knowledge, their clinic attendance and drug availability, with a focus on seven conditions accounting for a large share of child and maternal mortality in sub-Saharan Africa: malaria, tuberculosis, diarrhoea, pneumonia, diabetes, neonatal asphyxia and postpartum haemorrhage. METHODS: With nationally representative, cross-sectional data from ten countries in sub-Saharan Africa, collected using clinical vignettes (to assess provider knowledge), unannounced visits (to assess provider absenteeism) and visual inspections of facilities (to assess availability of drugs and equipment), we assess whether health providers are available and have sufficient knowledge and means to diagnose and treat patients suffering from common conditions amenable to primary healthcare. We draw on data from 8061 primary and secondary care facilities in Kenya, Madagascar, Mozambique, Nigeria, Niger, Senegal, Sierra Leone, Tanzania, Togo and Uganda, and 22 746 health workers including doctors, clinical officers, nurses and community health workers. Facilities were selected using a multistage cluster-sampling design to ensure data were representative of rural and urban areas, private and public facilities, and of different facility types. These data were gathered under the Service Delivery Indicators programme. RESULTS: Across all conditions and countries, healthcare providers were able to correctly diagnose 64% (95% CI 62% to 65%) of the clinical vignette cases, and in 45% (95% CI 43% to 46%) of the cases, the treatment plan was aligned with the correct diagnosis. For diarrhoea and pneumonia, two common causes of under-5 deaths, 27% (95% CI 25% to 29%) of the providers correctly diagnosed and prescribed the appropriate treatment for both conditions. On average, 70% of health workers were present in the facilities to provide care during facility hours when those workers are scheduled to be on duty. Taken together, we estimate that the likelihood that a facility has at least one staff present with competency and key inputs required to provide child, neonatal and maternity care that meets minimum quality standards is 14%. On average, poor clinical knowledge is a greater constraint in care readiness than drug availability or health workers' absenteeism in the 10 countries. However, we document substantial heterogeneity across countries in the extent to which drug availability and absenteeism matter quantitatively. CONCLUSION: Our findings highlight the need to boost the knowledge of healthcare workers to achieve greater care readiness. Training programmes have shown mixed results, so systems may need to adopt a combination of competency-based preservice and in-service training for healthcare providers (with evaluation to ensure the effectiveness of the training), and hiring practices that ensure the most prepared workers enter the systems. We conclude that in settings where clinical knowledge is poor, improving drug availability or reducing health workers' absenteeism would only modestly increase the average care readiness that meets minimum quality standards.

Extending health insurance to the rural population: an impact evaluation of China's new cooperative medical scheme.

In 2003, China launched a heavily subsidized voluntary health insurance program for rural residents. We combine differences-in-differences with matching methods to obtain impact estimates, using data collected from program administrators, health facilities and households. The scheme has increased outpatient and inpatient utilization, and has reduced the cost of deliveries. But it has not reduced out-of-pocket expenses per outpatient visit or inpatient spell. Out-of-pocket payments overall have not been reduced. We find heterogeneity across income groups and implementing counties. The program has increased ownership of expensive equipment among central township health centers but has had no impact on cost per case.

China's health system and its reform: a review of recent studies.

This paper provides a survey of the recent empirical research on China's 'old' health system (i.e. prior to the spate of reforms beginning in 2003). It argues that this research has enhanced our understanding of the system prior to 2003, in some cases reinforcing conclusions (e.g. the demand-inducement associated with perverse incentives) while in other cases suggesting a slightly less clear storyline (e.g. the link between insurance and out-of-pocket spending). It also concludes that the research to date points to the importance of careful evaluation of the current reforms, and its potential to modify policies as the rollout proceeds. Finally, it argues that the research on the pre-2003 system suggests that while the recently announced further reforms are a step in the right direction, the hoped-for improvements in China's health system will far more likely occur if the reforms become less timid in certain key areas, namely provider payments and intergovernmental fiscal relations.

Can insurance increase financial risk? The curious case of health insurance in China.

We analyze the effect of insurance on the probability of an individual incurring 'high' annual health expenses using data from three household surveys. All come from China, a country where providers are paid fee-for-service according to a schedule that encourages the overprovision of high-tech care and who are only lightly regulated. We define annual spending as 'high' if it exceeds a threshold of local average income and as 'catastrophic' if it exceeds a threshold of the household's own per capita income. Our estimates allow for different thresholds and for the possible endogeneity of health insurance (we use instrumental variables and fixed effects). Our main results suggest that in all three surveys health insurance increases the risk of high and catastrophic spending. Further analysis suggests that this is due to insurance encouraging people to seek care when sick and to seek care from higher-level providers.
