Heterogeneous impact of the "Seguro Popular" program on the utilization of obstetrical services in Mexico, 2001-2006: a multinomial probit model with a discrete endogenous variable

Equity in out-of-pocket health expenditure: Evidence from a health insurance program reform in Mexico

Background

The fragmentation of health systems in low- and middle-income countries (LMICs) deepens health inequities and shifts the economic burden of health care to families via out-of-pocket spending (OOPHE). This problem has been addressed by introducing public health insurance programs for poor people; however, there is a lack of knowledge about how equitable these programs are. We aimed to analyse the long-term effects of the Seguro Popular (SP) voluntary health insurance program, recently phased out and replaced by the Health Institute for Welfare (Instituto de Salud para el Bienestar (INSABI)), on OOPHE equity in the poor Mexican population.

Methods

We conducted a pooled cross-sectional analysis using eleven waves of the National Household Income and Expenditure Survey (2002-2020). We identified the effect of SP by selecting households without social security (with SP or without health insurance (n = 169 766)) and matched them by propensity score to reduce bias in the decision to enrol in SP. We estimated horizontal and vertical equity metrics and assessed their evolution across subpopulations.

Results

The program's entry years (2003-2010) show a positive redistributive effect associated with a focalised stage of the program, while oversaturation could have diluted these effects during 2010-2014, with adverse results in terms of vertical equity and re-ranking among insured families. SP is more horizontally inequitable than for those uninsured. Within SP, the redistributive effect could improve up to 13% if all families with similar expenditures were spending equal OOPHE and horizontal equity was eliminated. Regarding vertical equity, SP outperforms the insured population with middle-range coverage some years after the implementation, but this progress disappears.

Conclusions

To achieve universal health coverage, health authorities need to create and execute financial protection mechanisms that effectively address structural inequalities. This involves implementing a more comprehensive risk-pooling mechanism that makes social insurance sustainable in the long-run by increasing the social-economic influx of resources. It is essential to monitor oversaturation and financial sustainability to achieve optimal results. The replacement of the SP with INSABI highlights the complexity of maintaining a social insurance program where the ideology of different governments can influence the program structure, regulation, financing, and even its existence.

Effective access to health care in Mexico

Objectives

This paper assesses the impact of effective access on out-of-pocket health payments and catastrophic health expenditure. Effective access cannot be attained unless both health services and financial risk protection are accessible, affordable, and acceptable. Therefore, it represents a key determinant in the transition from fragmented health systems to universal coverage that many low- and middle-income countries face.

Methods

We use a definition of effective access as the utilization of health insurance when available. We conducted a cross-sectional analysis using the 2018 Mexican National Health Survey (ENSANUT) at the household level. The analysis is performed in two stages. The first stage is a multinomial analysis that captures the factor associated with choosing effective access against the alternative of paying privately. The second stage consists of an impact analysis regarding the decision of not choosing effective access in terms of out-of-pocket (OOP) health payments and catastrophic health expenditures (CHE). The analysis corrects for both the decision to buy insurance and the decision to pay for health care.

Results

We found that, on average, not choosing effective access increases OOP health payments by around 2300 pesos annually. Medicine payments are the most common factor in this increase. Nevertheless, outpatient and medicines health care are the main drivers of the increase in OOP health payments in all insurance beneficiaries. Not having effective access increases the probability of CHE health expenditures by 2.7 p.p. for the case of Social Security Insurance and 4.0 p.p. for Social Government insurance. Household enrolled in Prospera program for the poor are more likely to choose effective access while having household heads with more education and assets value does the opposite. Diabetes illnesses are associated with a higher probability of effective access.

Conclusion

Improving effective access is a middle step that cannot be disregarded when seeking universal coverage because OOP health payments and catastrophic outcomes are direct consequences. Public insurance in general, has around 50% effective access which remains a challenge in terms of health services utilization and health public policy design, calling for the need of better coordination across insurance types and pooling mechanisms to increase sustainability of needed health services.

A systematic review of the literature on the impact of the Seguro Popular

BACKGROUND

The Seguro Popular (SP) was launched in 2004 to increase access to healthcare and reduce catastrophic expenditures among the Mexican population. To document the evidence on its effectiveness, we conducted a systematic review of impact evaluations of the SP.

METHODS

We included papers using rigorous quasi-experimental designs to assess the effectiveness of the SP. We evaluated the quality of each study and presented the statistical significance of the effects by outcome category.

RESULTS

We identified 26 papers that met the inclusion criteria. Sixteen studies that evaluated the impact of SP on financial protection found consistent and statistically significant positive effects in 55% of the 65 outcomes analyzed. Nine studies evaluating utilization of health services for the general and infant populations found effectiveness on 40% of 30 outcomes analyzed. Concerning screening services for hypertension, diabetes, and cervical and prostate cancer, we found three studies evaluating 14 outcomes and finding significant effects on 50% of them. Studies looking at the impact of SP on diabetes, hypertension, and general health care and treatment evaluated 19 outcomes and found effects on 21% of them. One study assessed five diabetes monitoring services and found positive effects on four of them. The only study on morbidity and mortality found positive results on three of the four outcomes of interest.

CONCLUSION

We found mixed evidence on the impact of SP on financial protection, healthcare utilization, morbidity and mortality. In the 26 studies included in this review, researchers found positive effects in roughly half of the outcomes and null results on the rest.

The effects of trade-induced worker displacement on health and mortality in Mexico

Recent research in the U.S. links trade-induced job displacement to deaths of despair. Should we expect the same mortality response in developing countries? This paper analyzes the effect of a trade-induced negative shock to manufacturing employment on leading causes of mortality in Mexico between 1998 and 2013. I exploit cross-municipality variation in trade exposure based on differences in industry specialization before China's accession to the WTO in 2001 to identify labor-demand shocks that are concentrated in manufacturing. I find trade-induced job loss increased mortality from diabetes, raised obesity rates, reduced physical activity, and lowered access to health insurance. These deaths were offset by declines in mortality from ischemic heart disease and chronic pulmonary disease. These findings highlight that negative employment shocks have heterogeneous impacts on mortality in developing countries, where falling incomes lead to less access to health care and nutritious food, but also reduce alcohol and tobacco use.

Public health insurance and ethnic disparities in maternal health care: the case of vulnerable Mexican women over the last 25 years

This article examines the coverage in the continuum of antenatal-postnatal care for vulnerable women in Mexico according to indigenous status and assesses the influence of public health insurance strategies on the evolution of coverage over the last 25 years. We studied a total of 19 613 567 Mexican women, aged 12-54 years at last birth, based on a pooled cross-sectional analysis of data from the 1997, 2009, 2014 and 2018 waves of the National Survey of Demographic Dynamics. After describing sociodemographic characteristics and maternal-health coverage by indigenous status, we constructed a pooled fixed-effects and interaction multivariable regression model to assess the influence of the Seguro Popular programme on continuum of care. We estimated adjusted continuum of care coverage between 1994 and 2018 according to Seguro Popular affiliation and indigenous status. Prior to the Seguro Popular programme, crude coverage in the continuum of care for non-indigenous women stood at 14.5% [95% confidence interval (CI): 13.2-15.8%] or 11 percentage points higher than for indigenous women. During the last period of the programme, it rose to 46.5% [95% CI: 45.6-47.5%] and 34.1% [95% CI: 30.7-37.4%], respectively. Our regression analysis corroborated findings that, on average, indigenous women faced lower odds of benefiting from continuum of care [adjusted odds ratio (aOR) = 0.48, 95% CI: 0.40-0.57] than did their non-indigenous counterparts. It also revealed that coverage for indigenous women without Seguro Popular affiliation was 26.7% [95% CI: 23.3-30.1%] or 12 percentage points lower than for those with Seguro Popular affiliation (38.6%, 95% CI: 35.7-41.4%). Our regression results confirmed that the latter benefited from higher odds of continuum of care (aOR = 1.67, 95% CI: 1.36-2.26). Gaps between those of indigenous and non-indigenous status have persisted, but the Seguro Popular clearly contributed to reducing the coverage gaps between these two groups of women. Strategies yielding better outcomes are required to improve the structural conditions of indigenous populations.

Integrated community-based HIV and non-communicable disease care within microfinance groups in Kenya: study protocol for the Harambee cluster randomised trial

INTRODUCTION

In Kenya, distance to health facilities, inefficient vertical care delivery and limited financial means are barriers to retention in HIV care. Furthermore, the increasing burden of non-communicable diseases (NCDs) among people living with HIV complicates chronic disease treatment and strains traditional care delivery models. Potential strategies for improving HIV/NCD treatment outcomes are differentiated care, community-based care and microfinance (MF).

METHODS AND ANALYSIS

We will use a cluster randomised trial to evaluate integrated community-based (ICB) care incorporated into MF groups in medium and high HIV prevalence areas in western Kenya. We will conduct baseline assessments with n=900 HIV positive members of 40 existing MF groups. Group clusters will be randomised to receive either (1) ICB or (2) standard of care (SOC). The ICB intervention will include: (1) clinical care visits during MF group meetings inclusive of medical consultations, NCD management, distribution of antiretroviral therapy (ART) and NCD medications, and point-of-care laboratory testing; (2) peer support for ART adherence and (3) facility referrals as needed. MF groups randomised to SOC will receive regularly scheduled care at a health facility. Findings from the two trial arms will be compared with follow-up data from n=300 matched controls. The primary outcome will be VS at 18 months. Secondary outcomes will be retention in care, absolute mean change in systolic blood pressure and absolute mean change in HbA1c level at 18 months. We will use mediation analysis to evaluate mechanisms through which MF and ICB care impact outcomes and analyse incremental cost-effectiveness of the intervention in terms of cost per HIV suppressed person-time, cost per patient retained in care and cost per disability-adjusted life-year saved.

ETHICS AND DISSEMINATION

The Moi University Institutional Research and Ethics Committee approved this study (IREC#0003054). We will share data via the Brown University Digital Repository and disseminate findings via publication.

The effects of public health insurance in labor markets with informal jobs: Evidence from Mexico

This paper studies the labor market effects of the most significant public health insurance expansion in the Americas: Mexico's Seguro Popular (SP). To identify its impact, I exploit the staggered rollout of SP across municipalities. I find that SP increases labor supply by reducing the likelihood of informal workers exiting the labor market. This reduction is driven by women, who experience a 15% decrease in the probability of transitioning from informal employment to inactivity. I also find that this reduction is concentrated among female secondary earners residing in households with dependents. These findings suggest that SP may operate through a novel channel, namely that health insurance enables caregivers to continue working by reducing health shocks among dependents.

Publicly provided healthcare and migration

Publicly provided healthcare has received growing attention. Debates have been fuelled by evidence on improved health and reduced poverty, and concerns over adverse labour market effects; concerns that are, to date, only supported by mixed empirical findings. This article examines whether publicly provided healthcare influences the decision to migrate. The spatial and temporal variation in the expansion of a non-contributory health insurance programme in Mexico, combined with the panel dimension and the timing of household survey data allows causal identification of the effect of increased coverage on migration. Difference-in-differences estimates reveal that accessing healthcare for free raises internal migration. The effect on international migration, costlier by nature, is statistically insignificant. Potential mechanisms include better health, the alleviation of financial constraints and a greater propensity to work. Results point to the relevance of including household members who have migrated in assessing the impacts of social health policies. They suggest that publicly provided healthcare could have multiplier effects on economic development and welfare by enabling labour force detachment of working-age members in affiliated households.

Is it worth outsourcing essential public health services in China?-Evidence from Beilin District of Xi'an

BACKGROUND

Essential public health services (EPHS) is general welfare public health interventions led by the Chinese government and provided by the primary medical institutions to all residents. In Beilin District, Xi'an, EPHS producers can be divided into outsourced institutions and public institutions.

OBJECTIVE

Can outsourcing EPHS reduce costs and improve efficiency and quality? There is still no definite answer to this question. This paper compares the performance of outsourced institutions and public institutions in terms of efficiency and quality, explains the reasons for this phenomenon.

METHODS

This paper uses a theoretical and two-stage DEA model Based on a "triple subject" research framework.

RESULTS

The results show that the difference between public institutions and outsourced institutions is mainly reflected in service quality. When the quality is not measured, outsourced institutions' production efficiency is higher than that of public institutions. When there are quality measurements, the production efficiency of outsourced institutions is lower than that of public institutions.

CONCLUSIONS

Outsourced institutions perform worse than public institutions. The reason is that a bilateral monopolistic market structure has formed between local governments and outsourced institutions. This situation makes it difficult for the government to replace poor quality outsourced institutions under the constraints of a limited budget.

Tackling maternal mortality by improving technical efficiency in the production of primary health services: longitudinal evidence from the Mexican case

Ensuring regular and timely access to efficient and quality health services reduces the risk of maternal mortality. Specifically, improving technical efficiency (TE) can result in improved health outcomes. To date, no studies in Mexico have explored the connection of TE with either the production of maternal health services at the primary-care level or the maternal-mortality ratio (MMR) in populations without social security coverage. The present study combined data envelopment analysis (DEA), longitudinal data and selection bias correction methods with the purpose of obtaining original evidence on the impact of TE on the MMR during the period 2008-2015. The results revealed that MMR fell 0.36% (P < 0.01) for every percentage point increase in TE at the jurisdictional level or elasticity TE-MMR. This effect proved lower in highly marginalized jurisdictions and disappeared entirely in those with low- or medium-marginalization levels. Our findings also highlighted the relevance of certain social and economic aspects in the attainment of TE by jurisdictions. This clearly demonstrates the need for comprehensive, cross-cutting policies capable of modifying the structural conditions that generate vulnerability in specific population groups. In other words, achieving an effective and sustainable reduction in the MMR requires, inter alia, that the Mexican government review and update two essential elements: the criteria behind resource allocation and distribution, and the control mechanisms currently in place for executing and ensuring accountability in these two functions.

Impact of the 'Seguro Médico Siglo XXI' medical insurance programme on neonatal and infant mortality in Mexico, 2006-14: an ecological approach to estimation

The 'Seguro Médico Siglo XXI' (SMSXXI), a universal coverage medical insurance programme for children under 5 years of age, started in 2006 to help avoid catastrophic health expenditures in poor families without social security in Mexico. The study used information from the National Health Information System for the 2006-14 period. An ecological approach was followed with a panel of the 2457 municipalities of Mexico as the units of analysis. The outcome variables were the municipality-level neonatal mortality and infant mortality rates in population without access to social security. The programme variable was the coverage of the SMSXXI programme at the municipality level, expressed as a proportion. Demographic and economic variables defined at the municipality level were included as covariates. Impact was estimated by fitting a fixed-effects negative binomial regression model. Results reveal that the SMSXXI significantly reduced both infant and neonatSal mortality in the target population, although in a non-linear fashion, with minimum mortality levels found around the 70% coverage range. The effect is mostly given by the transition from the first quintile to the fourth quintile of coverage (<13% vs 70.5-93.7% coverage), and it is attenuated significantly at coverage levels very close to or at 100%. The observed risk reduction amounted to an estimated total of 11 358 infant deaths being avoided due to the SMSXXI during the 2006-14 period, of which 48% were neonatal. In conclusion, we found a significant impact of the SMSXXI programme on both infant mortality and neonatal mortality. An attenuation of the effect of the insurance on mortality rates at levels close to 100% coverage may reflect the saturation of health units in detriment of the quality of care.

Improving the effective maternal-child health care coverage through synergies between supply and demand-side interventions: evidence from Mexico

Background

Over the last two decades, the Mexican government has released several efforts to achieve universal health coverage (UHC), based on the principles of fairness and social protection, to reduce the inequities in utilization, access, and quality of care existing in the health system. Two of the most important social public policies that have targeted the population without access to social security include the 1997 conditional cash transfers (CCT) program known as Prospera (formerly Oportunidades or Progresa) and the Seguro Popular de Salud (SPS by its Spanish initials), launched in 2003. These two programs, so far, have survived changes in the federal administrations being the most longstanding social programs targeting poor (or unprotected) populations ever in the history of modern Mexico. We tested the existence of positive synergies between demand-side (or CCT-Prospera) and supply-side (or Seguro Popular de Salud, SPS) social programs in the achievement of effective coverage (EC) of maternal-child health interventions in Mexico.

Methods

We performed a retrospective-cohort analysis to 6413 women aged 12-49 years who participated in a probabilistic survey conducted in 2012. We calculated EC as the product of three indexes: need, utilization and quality of health care. Correlates of EC were identified estimating a logistic regression model. We also presented adjusted EC by specific women groups.

Results

EC among beneficiaries of both programs was similar to estimates in Social Security affiliates (54%). For those not affiliated to any of the programs or those who received benefits for only one of them, the EC was 47.6% and 45.5% respectively. Adjusted estimates of EC suggest that overall, having both programs (Prospera + SPS) has a positive effect on maternal and child care coverage, which makes the observed differences in EC not statistically significant between those affiliated to both programs in comparison with the observed in the population with social security.

Conclusions

Results support positive synergies between Prospera and SPS in the reduction of the gaps in EC. The most vulnerable population groups need to be reached by the combination of these programs so that public health efforts translate into greater EC of maternal health services and better maternal-child outcomes.

Out-Of-Pocket Expenditures on Dental Care for Schoolchildren Aged 6 to 12 Years: A Cross-Sectional Estimate in a Less-Developed Country Setting

Aim: The objective of this study was to estimate the Out-Of-Pocket Expenditures (OOPEs) incurred by households on dental care, as well as to analyze the sociodemographic, economic, and oral health factors associated with such expenditures. Method: A cross-sectional study was conducted among 763 schoolchildren in Mexico. A questionnaire was distributed to parents to determine the variables related to OOPEs on dental care. The amounts were updated in 2017 in Mexican pesos and later converted to 2017 international dollars (purchasing power parities-PPP US $). Multivariate models were created: a linear regression model (which modeled the amount of OOPEs), and a logistic regression model (which modeled the likelihood of incurring OOPEs). Results: The OOPEs on dental care for the 763 schoolchildren were PPP US $53,578, averaging a PPP of US $70.2 ± 123.7 per child. Disbursements for treatment were the principal item within the OOPEs. The factors associated with OOPEs were the child's age, number of dental visits, previous dental pain, main reason for dental visit, educational level of mother, type of health insurance, household car ownership, and socioeconomic position. Conclusions: The average cost of dental care was PPP US $70.2 ± 123.7. Our study shows that households with higher school-aged children exhibiting the highest report of dental morbidity-as well as those without insurance-face the highest OOPEs. An array of variables were associated with higher expenditures. In general, higher-income households spent more on dental care. However, the present study did not estimate unmet needs across the socioeconomic gradient, and thus, future research is needed to fully ascertain disease burden.

Government expenditure on health and maternal mortality in México: A spatial-econometric analysis

OBJECTIVE

To assess the relationship between government expenditure on maternal health (GE) and maternal mortality (MM) in Mexican poor population between 2000 and 2015 in the 2457 Mexican municipalities.

METHODS

Using administrative data, we performed the analysis in three stages: First, we tested the presence of selection bias in MM. Next, we assessed the presence of spatial dependence in the incidence and severity of MM. Finally, we estimated a spatial error model considering the correction of estimates for the spatial dependence and selection bias assessed before.

RESULTS

MM and GE were not randomly distributed throughout the Mexican territory; the most socially vulnerable municipalities exhibited the highest levels of MM severity but the lowest levels of GE and available human and physical resources for maternal health; the incidence of MM was independent of GE; elasticity of GE-severity in MM was -4% (P < 0.01).

CONCLUSIONS

Resource allocation for maternal health must move towards a more comprehensive vision, and efforts to achieve an effective delivery of universal health services must improve, particularly regarding the most vulnerable municipalities.

Welfare effects of health insurance in Mexico: The case of Seguro Popular de Salud

This study contributes with original empirical evidence on the distributional and welfare effects of one of the most important health policies implemented by the Mexican government in the last decade, the Seguro Popular de Salud (SPS). We analyze the effect of SPS on households' welfare using a decomposable index that considers insured and uninsured households' response to out-of-pocket (OOP) payments using both social welfare weights and inequality aversion. The disaggregation of the welfare index allows us to explore the heterogeneity of the SPS impact on households' welfare. We applied propensity score matching to reduce the self-selection bias of being SPS insured. Overall results suggest non-conclusive results of the impact of SPS on households' welfare. When we disaggregated the welfare index by different sub-population groups, our results suggest that households' beneficiaries of SPS with older adults or living in larger cities are better protected against OOP health care payments than their uninsured counterparts. However, no effect was found among SPS-insured households living in rural and smaller cities, which is a result that could be attributed to limited access to health resources in these regions. Scaling up health insurance coverage is a necessary but not sufficient condition to ensure the protection of SPS coverage against financial risks among the poor.

Health Insurance and the Aging: Evidence From the Seguro Popular Program in Mexico

Aimed at covering the large fraction of workers in the informal sector without access to a social security program, the Mexican public health insurance program Seguro Popular began in 2002 and now reaches more than 50 million individuals. We estimate impacts of Seguro Popular for the population aged 50 and older on a set of indicators related to health care including utilization, diagnostic/preventive tests, and treatment conditional on being ill. Using the longitudinal Mexican Health and Aging Study over the period 2001-2012, we conduct before and after difference-in-difference matching impact estimators. Our results suggest large and important effects of the Program on utilization and diagnostic tests. We find overall smaller effects on the probability of being in treatment for individuals with chronic diseases, but these effects are concentrated in rural areas with relatively more health services versus rural areas with lower levels of health services. These results suggest that, to the extent that health services become more available in rural areas lacking services, effects of health insurance may increase.

Public expenditure and healthcare utilization: the case of reproductive health care in India

An important reason for public intervention in health in developing countries is to address the issue of accessibility. However, numerous studies have found inconclusive evidence of the effect of public expenditure on health outcomes. Here, I revisit the debate by examining the effect of public expenditure on the use of health services, which is an important link between expenditure and outcomes. I use data from two recent waves of the National Family Health Survey of India to study the role of public expenditure on the use of healthcare services during pregnancy and childbirth. India has high state-level variations in the use of prenatal care and delivery by skilled personnel as well as levels of public expenditure. I exploit the variation in public expenditure to identify its effect on the use of healthcare services, controlling for other confounding factors. The results show a significant effect of public expenditure at the state level on the use of both prenatal and delivery care at the individual level. Also, there is no evidence of public expenditure crowding out private expenditure. Further, there is strong evidence that public expenditure reaches the desired targets. The results highlight the positive implications of raising public expenditure for healthcare use of pregnancy and childbirth services in the Indian context.

Use of performance metrics for the measurement of universal coverage for maternal care in Mexico

This study provides evidence for those working in the maternal health metrics and health system performance fields, as well as those interested in achieving universal and effective health care coverage. Based on the perspective of continuity of health care and applying quasi-experimental methods to analyse the cross-sectional 2009 National Demographic Dynamics Survey (n = 14 414 women), we estimated the middle-term effects of Mexico's new public health insurance scheme, Seguro Popular de Salud (SPS) (vs women without health insurance) on seven indicators related to maternal health care (according to official guidelines): (a) access to skilled antenatal care (ANC); (b) timely ANC; (c) frequent ANC; (d) adequate content of ANC; (e) institutional delivery; (f) postnatal consultation and (g) access to standardized comprehensive antenatal and postnatal care (or the intersection of the seven process indicators). Our results show that 94% of all pregnancies were attended by trained health personnel. However, comprehensive access to ANC declines steeply in both groups as we move along the maternal healthcare continuum. The percentage of institutional deliveries providing timely, frequent and adequate content of ANC reached 70% among SPS women (vs 64.7% in the uninsured), and only 57.4% of SPS-affiliated women received standardized comprehensive care (vs 53.7% in the uninsured group). In Mexico, access to comprehensive antenatal and postnatal care as defined by Mexican guidelines (in accordance to WHO recommendations) is far from optimal. Even though a positive influence of SPS on maternal care was documented, important challenges still remain. Our results identified key bottlenecks of the maternal healthcare continuum that should be addressed by policy makers through a combination of supply side interventions and interventions directed to social determinants of access to health care.

Contraceptive knowledge and use among women living in the poorest areas of five Mesoamerican countries

OBJECTIVE

To identify factors associated with contraceptive use among women in need living in the poorest areas in five Mesoamerican countries: Guatemala, Honduras, Nicaragua, Panama and State of Chiapas (Mexico).

STUDY DESIGN

We analyzed baseline data of 7049 women of childbearing age (15-49 years old) collected for the Salud Mesoamérica Initiative. Data collection took place in the 20% poorest municipalities of each country (July, 2012-August, 2013).

RESULTS

Women in the poorest areas were very poorly informed about family planning methods. Concern about side effects was the main reason for nonuse. Contraceptive use was lower among the extremely poor (<$1.25 USD PPP per day) [odds ratio (OR): 0.75; confidence interval (CI): 0.59-0.96], those living more than 30 min away from a health facility (OR 0.71, CI: 0.58-0.86), and those of indigenous ethnicity (OR 0.50, CI: 0.39-0.64). Women who were insured and visited a health facility also had higher odds of using contraceptives than insured women who did not visit a health facility (OR 1.64, CI: 1.13-2.36).

CONCLUSIONS

Our study showed low use of contraceptives in poor areas in Mesoamerica. We found the urgent need to improve services for people of indigenous ethnicity, low education, extreme poverty, the uninsured, and adolescents. It is necessary to address missed opportunities and offer contraceptives to all women who visit health facilities. Governments should aim to increase the public's knowledge of long-acting reversible contraception and offer a wider range of methods to increase contraceptive use.

IMPLICATIONS

We show that unmet need for contraception is higher among the poorest and describe factors associated with low use. Our results call for increased investments in programs and policies targeting the poor to decrease their unmet need.

The Impact of Social Health Insurance on Diabetes and Hypertension Process Indicators among Older Adults in Mexico

OBJECTIVE

To examine the impact of Seguro Popular (Mexican social health insurance for the poor; SP) on diabetes and hypertension care, intermediate process indicators for older adults (>50 years): pharmacological treatment, blood glucose tests, the use of complementary and alternative medicine (CAM), and adherence to their nutrition and exercise program. (CAM was defined as products or practices that were not part of the medical standard of care.)

DATA SOURCES/STUDY SETTING

Repeated cross-sectional surveys from Encuesta Nacional de Salud y Nutrición (Mexican Health and Nutrition Survey, ENSANUT), a nationally representative health and nutrition survey sampling N = 45,294 older adults in 2000, N = 45,241 older adults in 2005-2006, and N = 46,277 older adults in 2011-2012.

STUDY DESIGN

Fixed-effects instrumental variable (FE-IV) repeated cross-sectional at the individual level with municipality fixed-effects estimation was performed.

PRINCIPAL FINDINGS

We found a marginally significant effect of SP on the use of insulin and oral agents (40 percentage points). Contrary to that expected, no other significant differences were found for diabetes or hypertension treatment and care indicators.

CONCLUSIONS

Social health insurance for the poor improved some but not all health care process indicators among diabetic and hypertensive older people in Mexico.

Prevalence, Disparities, And Determinants Of Primary Cesarean Births Among First-Time Mothers In Mexico

Mexico has the second-highest prevalence of cesarean deliveries in the Americas, behind Brazil. Having had a previous cesarean delivery is highly predictive of having subsequent cesarean deliveries, yet evidence on the drivers of primary (that is, first-time) cesarean deliveries is sparse. Using 2014 Mexican birth certificate data and performing population-level analyses of data on 600,124 first-time mothers giving birth after at least thirty-seven weeks of gestation, we examined the prevalence and determinants of primary cesarean deliveries. We found a very high prevalence of cesarean deliveries among these women-48.7 percent-and wide variations across insurance coverage types. Enrollees in Seguro Popular, the public health insurance program introduced in 2003 for the previously uninsured and gradually rolled out nationally, had a cesarean rate of 40 percent, while women insured through the Social Security Institute for Civil Servants had a rate of 78 percent. The lower risk of primary cesarean deliveries among Seguro Popular enrollees persisted after adjustment for covariates. Rates of primary cesarean deliveries were particularly high in private birthing facilities for all first-time mothers. Reducing the rate of cesarean deliveries in Mexico will require interventions across types of insurance and birthing facilities and will also require targeted public health messaging.

Mexico's Seguro Popular Appears To Have Helped Reduce The Risk Of Preterm Delivery Among Women With Low Education

Beginning in 2001 Mexico established Seguro Popular, a health insurance scheme aimed at providing coverage to its large population of uninsured people. While recent studies have evaluated the health benefits of Seguro Popular, evidence on perinatal health outcomes is lacking. We conducted a population-based study using Mexican birth certificate data for 2010 to assess the relationship between enrollment in Seguro Popular and preterm delivery among first-time mothers with singleton births in Mexico. Seguro Popular enrollees with no formal education had a far greater reduction in risk of preterm delivery, while enrollees with any formal education experienced only slight reduction in risk, after maternal age, marital status, education level, mode of delivery, and trimester in which prenatal care was initiated were controlled for. Seguro Popular appears to facilitate access to health services among mothers with low levels of education, reducing their risk for preterm delivery. Providing broad-scale health insurance coverage may help improve perinatal health outcomes in this vulnerable population.

Health facility and skilled birth deliveries among poor women with Jamkesmas health insurance in Indonesia: a mixed-methods study

BACKGROUND

The growing momentum for quality and affordable health care for all has given rise to the recent global universal health coverage (UHC) movement. As part of Indonesia's strategy to achieve the goal of UHC, large investments have been made to increase health access for the poor, resulting in the implementation of various health insurance schemes targeted towards the poor and near-poor, including the Jamkesmas program. In the backdrop of Indonesia's aspiration to reach UHC is the high rate of maternal mortality that disproportionally affects poor women. The objective of this study was to evaluate the association of health facility and skilled birth deliveries among poor women with and without Jamkesmas and explore perceived barriers to health insurance membership and maternal health service utilization.

METHODS

We used a mixed-methods design. Utilizing data from the 2012 Indonesian Demographic and Health Survey (n = 45,607), secondary analysis using propensity score matching was performed on key outcomes of interest: health facility delivery (HFD) and skilled birth delivery (SBD). In-depth interviews (n = 51) were conducted in the provinces of Jakarta and Banten among poor women, midwives, and government representatives. Thematic framework analysis was performed on qualitative data to explore perceived barriers.

RESULTS

In 2012, 63.0% of women did not have health insurance; 19.1% had Jamkesmas. Poor women with Jamkesmas were 19% (OR = 1.19 [1.03-1.37]) more likely to have HFD and 17% (OR = 1.17 [1.01-1.35]) more likely to have SBD compared to poor women without insurance. Qualitative interviews highlighted key issues, including: lack of proper documentation for health insurance registration; the preference of pregnant women to deliver in their parents' village; the use of traditional birth attendants; distance to health facilities; shortage of qualified health providers; overcrowded health facilities; and lack of health facility accreditation.

CONCLUSIONS

Poor women with Jamkesmas membership had a modest increase in HFD and SBD. These findings are consistent with economic theory that health insurance coverage can reduce financial barriers to care and increase service uptake. However, factors such as socio-cultural beliefs, accessibility, and quality of care are important elements that need to be addressed as part of the national UHC agenda to improve maternal health services in Indonesia.

A Performance Analysis of Public Expenditure on Maternal Health in Mexico

We explore the relationship between public expenditure, coverage of adequate ANC (including timing, frequent and content), and the maternal mortality ratio--adjusted by coverage of adequate ANC--observed in Mexico in 2012 at the State level. Additionally, we examine the inequalities and concentration of public expenditure between populations with and without Social Security. Results suggest that in the 2003-2011 period, the public expenditure gap between women with and without Social Security decreased 74%, however, the distribution is less equitable among women without Social Security, across the States. Despite high levels of coverage on each dimension of ANC explored, coverage of adequate ANC was lower among Social Security than non-Social Security women. This variability results in differences up to 1.5 times in State-adjusted maternal mortality rate at the same level of expense and maternal mortality rate, respectively. The increase in the economic resources is only a necessary condition for achieving improved health outcomes. Providing adequate health services and achieving efficient, effective and transparent use of resources in health, are critical elements for health systems performance. The attainment of universal effective coverage of maternal health and reducing maternal mortality in Mexico, requires the adjustment of policy innovations including the rules of allocation and execution of health resources. Health policies should be designed on a more holistic view promoting a balance between accessibility, effective implementation and rigorous stewardship.

Financing Maternal Health and Family Planning: Are We on the Right Track? Evidence from the Reproductive Health Subaccounts in Mexico, 2003-2012

OBJECTIVE

To analyze whether the changes observed in the level and distribution of resources for maternal health and family planning (MHFP) programs from 2003 to 2012 were consistent with the financial goals of the related policies.

MATERIALS AND METHODS

A longitudinal descriptive analysis of the Mexican Reproductive Health Subaccounts 2003-2012 was performed by financing scheme and health function. Financing schemes included social security, government schemes, household out-of-pocket (OOP) payments, and private insurance plans. Functions were preventive care, including family planning, antenatal and puerperium health services, normal and cesarean deliveries, and treatment of complications. Changes in the financial imbalance indicators covered by MHFP policy were tracked: (a) public and OOP expenditures as percentages of total MHFP spending; (b) public expenditure per woman of reproductive age (WoRA, 15-49 years) by financing scheme; (c) public expenditure on treating complications as a percentage of preventive care; and (d) public expenditure on WoRA at state level. Statistical analyses of trends and distributions were performed.

RESULTS

Public expenditure on government schemes grew by approximately 300%, and the financial imbalance between populations covered by social security and government schemes decreased. The financial burden on households declined, particularly among households without social security. Expenditure on preventive care grew by 16%, narrowing the financing gap between treatment of complications and preventive care. Finally, public expenditure per WoRA for government schemes nearly doubled at the state level, although considerable disparities persist.

CONCLUSIONS

Changes in the level and distribution of MHFP funding from 2003 to 2012 were consistent with the relevant policy goals. However, improving efficiency requires further analysis to ascertain the impact of investments on health outcomes. This, in turn, will require better financial data systems as a precondition for improving the monitoring and accountability functions in Mexico.

Access to Medicines by Seguro Popular Beneficiaries: Pending Tasks towards Universal Health Coverage

OBJECTIVE

In the context of aiming to achieve universal health coverage in Mexico, this study compares access to prescribed medicines (ATPM) between Seguro Popular (SP) and non-SP affiliated outpatient health service users.

MATERIALS AND METHODS

ATPM by 6,123 users of outpatient services was analyzed using the National Health and Nutrition Survey 2012. Adjusted bi-probit models were performed incorporating instrumental variables.

RESULTS

17.3% of SP and 10.1% of the non-SP population lacked ATPM. Two-thirds of all outpatient SP and 18.5% of all outpatient non-SP received health services at Ministry of Health facilities, among whom, 64.6 and 53.6% of the SP and non-SP population respectively reported ATPM at these facilities. Lack of medicines in health units, chronic health problems (compared to acute conditions) and prescription ≥3 medicines were risk factors for non-ATPM. Adjusted models suggest that when using Ministry of Health services, the SP population has a higher probability of ATMP compared to the non-SP population.

CONCLUSION

Given the aspirations of achieving universal health coverage in Mexico, it is important to increase ATPM in Ministry of Health facilities thereby ensuring basic rights to health care are met.

Type of Insurance and Use of Preventive Health Services Among Older Adults in Mexico

OBJECTIVE

The main purpose of this article was to assess the differences between Seguro Popular (SP) and employer-based health insurance in the use of preventive services, including screening tests for diabetes, cholesterol, hypertension, cervical cancer, and prostate cancer among older adults at more than a decade of health care reform in Mexico.

METHOD

Logistic regression models were used with data from the Mexican Health and Nutrition Survey, 2012.

RESULTS

After adjusting for other factors influencing preventive service utilization, SP enrollees were more likely to use screening tests for diabetes, cholesterol, hypertension, and cervical cancer than the uninsured; however, those in employment-based and private insurances had higher odds of using preventive care for most of these services, except Pap smears.

DISCUSSION

Despite all the evidence that suggests that SP has increased access to health insurance for the poor, inequalities in health care access and utilization still exist in Mexico.

Government health insurance for people below poverty line in India: quasi-experimental evaluation of insurance and health outcomes

OBJECTIVES

To evaluate the effects of a government insurance program covering tertiary care for people below the poverty line in Karnataka, India, on out-of-pocket expenditures, hospital use, and mortality.

DESIGN

Geographic regression discontinuity study.

SETTING

572 villages in Karnataka, India.

PARTICIPANTS

31,476 households (22,796 below poverty line and 8680 above poverty line) in 300 villages where the scheme was implemented and 28,633 households (21,767 below poverty line and 6866 above poverty line) in 272 neighboring matched villages ineligible for the scheme.

INTERVENTION

A government insurance program (Vajpayee Arogyashree scheme) that provided free tertiary care to households below the poverty line in about half of villages in Karnataka from February 2010 to August 2012.

MAIN OUTCOME MEASURE

Out-of-pocket expenditures, hospital use, and mortality.

RESULTS

Among households below the poverty line, the mortality rate from conditions potentially responsive to services covered by the scheme (mostly cardiac conditions and cancer) was 0.32% in households eligible for the scheme compared with 0.90% among ineligible households just south of the eligibility border (difference of 0.58 percentage points, 95% confidence interval 0.40 to 0.75; P<0.001). We found no difference in mortality rates for households above the poverty line (households above the poverty line were not eligible for the scheme), with a mortality rate from conditions covered by the scheme of 0.56% in eligible villages compared with 0.55% in ineligible villages (difference of 0.01 percentage points, -0.03 to 0.03; P=0.95). Eligible households had significantly reduced out-of-pocket health expenditures for admissions to hospitals with tertiary care facilities likely to be covered by the scheme (64% reduction, 35% to 97%; P<0.001). There was no significant increase in use of covered services, although the point estimate of a 44.2% increase approached significance (-5.1% to 90.5%; P=0.059). Both reductions in out-of-pocket expenditures and potential increases in use might have contributed to the observed reductions in mortality.

CONCLUSIONS

Insuring poor households for efficacious but costly and underused health services significantly improves population health in India.

Primary health care utilization by the mexican indigenous population: the role of the Seguro popular in socially inequitable contexts

OBJECTIVE

To analyze the relationship between primary health care utilization and extended health insurance coverage under the Seguro Popular (SP) among Mexican indigenous people.

METHODOLOGY

A cross-sectional analysis was conducted using data from the Mexican National Nutrition Survey 2012 (n = 194,758). Quasi-experimental matching methods and nonlinear regression probit models were used to estimate the influence of SP on primary health care utilization.

RESULTS

25% of the Mexican population reported having no health insurance coverage, while 59% of indigenous versus 35% of non-indigenous reported having SP coverage. Health problems were reported by 13.9% of indigenous vs. 10.5% of non-indigenous; of these, 52.8% and 57.7% respectively, received primary health care (p<0.05). Economic barriers were the most frequent reasons for not using primary health care services. The probability of utilizing primary health care services was 11.5 percentage points higher (p<0.01) for indigenous SP affiliates in comparison with non-indigenous, in similar socioeconomic conditions.

CONCLUSION

Socioeconomic conditions, not ethnicity per-se, determine whether people utilize primary health care services. Therefore, SP can be conceived as a public policy strategy which acts as a social buffer by enhancing health care utilization regardless of ethnicity. Further analysis is required to explore the potential gaps as a result of SP coverage among socially vulnerable groups.

Boosting health insurance coverage in developing countries: do conditional cash transfer programmes matter in Mexico?

BACKGROUND

Achieving universal health insurance coverage is a goal for many developing countries. Even when universal health insurance programmes are in place, there are significant barriers to reaching the lowest socio-economic groups such as a lack of awareness of the programmes or knowledge of the benefits to participating in the insurance market. Conditional cash transfer (CCT) programmes can encourage participation through mandatory health education classes, increased contact with the health care system and cash payments to reduce costs of participating in the insurance market.

OBJECTIVE

To explore if participation in a CCT programme in Mexico, Oportunidades, is significantly associated with self-reported enrolment in a public health insurance programme.

METHODS

Cross-sectional data from 2007 collected on 29 595 Mexican households where the household head is aged between ages 15 and 60 were analysed. A logit model was used to estimate the association between Oportunidades participation and awareness of enrolment in a public health insurance programme.

RESULTS

Participation in the Oportunidades programme is associated with a 25% higher likelihood of being actively aware of enrolment in Seguro Popular, a public health insurance scheme for the lowest socio-economic groups.

CONCLUSIONS

Participation in the Oportunidades CCT programme is positively associated with awareness of enrolment in public health insurance. CCT programmes may be used to promote participation of the lowest socio-economic groups in universal public health insurance systems. This is crucial to achieving universal health insurance coverage in developing countries.

'Been there done that': disentangling option value effects from user heterogeneity when valuing natural resources with a use component

Endogeneity bias arises in contingent valuation studies when the error term in the willingness to pay (WTP) equation is correlated with explanatory variables because observable and unobservable characteristics of the respondents affect both their WTP and the value of those variables. We correct for the endogeneity of variables that capture previous experience with the resource valued, humpback whales, and with the geographic area of study. We consider several endogenous behavioral variables. Therefore, we apply a multivariate Probit approach to jointly model them with WTP. In this case, correcting for endogeneity increases econometric efficiency and substantially corrects the bias affecting the estimated coefficients of the experience variables, by isolating the decreasing effect on option value caused by having already experienced the resource. Stark differences are unveiled between the marginal effects on WTP of previous experience of the resource in an alternative location versus experience in the location studied, Newfoundland and Labrador (Canada).

Does progress towards universal health coverage improve population health?

Many commentators, including WHO, have advocated progress towards universal health coverage on the grounds that it leads to improvements in population health. In this report we review the most robust cross-country empirical evidence on the links between expansions in coverage and population health outcomes, with a focus on the health effects of extended risk pooling and prepayment as key indicators of progress towards universal coverage across health systems. The evidence suggests that broader health coverage generally leads to better access to necessary care and improved population health, particularly for poor people. However, the available evidence base is limited by data and methodological constraints, and further research is needed to understand better the ways in which the effectiveness of extended health coverage can be maximised, including the effects of factors such as the quality of institutions and governance.

Is RSBY India's platform to implementing universal hospital insurance?

Background & objectives:

In 2008, India's Labour Ministry launched a hospital insurance scheme called Rashtriya Swasthya Bima Yojana (RSBY) covering ‘Below Poverty Line’ (BPL) households. RSBY is implemented through insurance companies; premiums are subsidized by Union and States governments (75 : 25%). We examined RSBY's enrolment of BPL, costs vs. budgets and policy ramifications.

Methods:

Numbers of BPL are obtained by following criteria of two committees appointed for this task. District-specific premiums are weighted to obtain national average premiums. Using the BPL estimates and national premiums, we calculated overall expected costs of full roll-out of the RSBY per annum, and compared it to Union government budget allocations.

Results:

By March 31, 2011, RSBY enrolled about 27.8 per cent of the number of BPL households following the Tendulkar Committee estimates (37.6% following the Lakdawala Committee criteria). The average national weighted premium was 530 per household per year in 2011. The expected cost of premium to the union government of enrolling the entire BPL population in financial year (FY) 2010-11 would be 33.5 billion using Tendulkar count of BPL (or 24.6 billion following Lakdawala count), representing about 0.3 per cent (or 0.2%, respectively) of the total union budget. The RSBY budget allocation for FY 2010-11 was only about 0.037 per cent of the total union budget, sufficient to pay premiums of only 34 per cent of the BPL households enrolled by March 31, 2011.

Interpretation & conclusions:

RSBY could be the platform for universal health insurance when (i) the budget allocation will match the required funds for maintenance and expansion of the scheme; (ii) the scheme would ensure that beneficiaries’ rights are legally anchored; and (iii) RSBY would attract large numbers of premium-paying (non-BPL) households.

Moral hazard and selection among the poor: evidence from a randomized experiment

Not only does economic theory predict high-risk individuals to be more likely to purchase insurance, but insurance coverage is also thought to crowd out precautionary activities. In spite of stark theoretical predictions, there is conflicting empirical evidence on adverse selection, and evidence on ex ante moral hazard is very scarce. Using data from the Seguro Popular Experiment in Mexico, this paper documents patterns of selection on observables into health insurance as well as the existence of non-negligible ex ante moral hazard. More specifically, the findings indicate that (i) agents in poor self-assessed health prior to the intervention have, all else equal, a higher propensity to take up insurance; and (ii) insurance coverage reduces the demand for self-protection in the form of preventive care. Curiously, however, individuals do not sort based on objective measures of their health.

Analysis of changes in the association of income and the utilization of curative health services in Mexico between 2000 and 2006

BACKGROUND

A common characteristic of health systems in most developing countries is unequal access to health services. As a result, members of the poorest population groups often do not receive formal attention for health services, because they cannot afford it. In 2001 in Mexico, to address income-related differences in the use of health services, the government launched a major healthcare reform, which includes a health insurance program called Seguro Popular, aimed at improving healthcare access among poor, uninsured residents. This paper analyzes the before and after changes in the demand for curative ambulatory health services focusing on the association of income-related characteristics and the utilization of formal healthcare providers vs. no healthcare service utilization.

METHODS

By using two nationally representative health surveys (ENSA-2000 and ENSANUT-2006), we modeled an individual's decision when experiencing an illness to use services provided by the (1) Ministry of Health (MoH), (2) social security, (3) private entities, or (4) to not use formal services (no healthcare service utilization).

RESULTS

Poorer individuals were more likely in 2006 than in 2000 to respond to an illness by using formal healthcare providers. Trends in provider selection differed, however. The probability of using public services from the MoH increased among the poorest population, while the findings indicated an increase in utilization of private health services among members of low- and middle-income groups. No significant change was seen among formal workers -covered by social security services-, regardless of socioeconomic status.

CONCLUSIONS

Overall, for 2006 the Mexican population appears less differentiated in using healthcare across economic groups than in 2000. This may be related, in part, to the implementation of Seguro Popular, which seems to be stimulating healthcare demand among the poorest and previously uninsured segment of the population. Still, public health authorities need to address the remaining income-related healthcare utilization differences, the differences in quality between public and private health services, and the general perception that MoH facilities offer inferior services.

Analysis of the distributional impact of out-of-pocket health payments: evidence from a public health insurance program for the poor in Mexico

Many governments have health programs focused on improving health among the poor and these have an impact on out-of-pocket health payments made by individuals. Therefore, one of the objectives of these programs is to reach the poorest and reduce their out-of-pocket expenditure. In this paper we propose the distributional poverty impact approach to measure the poverty impact of out-of-pocket health payments of different health financing policies. This approach is comparable to the impoverishment methodology proposed by Wagstaff and van Doorslaer (2003) that compares poverty indices before and after out-of-pocket health payments. In order to escape the specification of a particular poverty index, we use the marginal dominance approach that uses non-intersecting curves and can rank poverty reducing health financing policies. We present an empirical application of the out-of-pocket health payments for an innovative social financing policy implemented in Mexico named Seguro Popular. The paper finds evidence that Seguro Popular program has a better distributional poverty impact when families face illness when compared to other poverty reducing policies. The empirical dominance approach uses data from Mexico in 2006 and considers international poverty standards of $2 per person per day.

[Impact of "Seguro Popular" on catastrophic and out-of-pocket health expenditures in rural and urban Mexico, 2005-2008]

OBJECTIVE

To estimate the effect of "Seguro Popular" (SP) on the incidence of catastrophic health expenditure (CHE) and out-of-pocket (OOP) health expenditure in the medium term.

MATERIAL AND METHODS

We used the 'Encuesta de Evaluación del SP' --SP Survey Evaluation-- (2005-2008). We analyzed the SP effect on the rural cohort during two years of follow-up (2006 and 2008) and in the urban cohort during one year of follow-up (2008).

RESULTS

At the local level (regional clusters) we did not find an effect of the SP. At the household level we found a protective effect of SP on CHE and the OOP health payments in outpatient and hospitalization in rural areas; and a significant effect on the reduction of OOP health payments in outpatient services in urban zones.

CONCLUSIONS

SP seems to be an effective program to protect poor household against out-of-pocket health expenditures in the medium term.

Health insurance for the poor: impact on catastrophic and out-of-pocket health expenditures in Mexico

The goal of Seguro Popular (SP) in Mexico was to improve the financial protection of the uninsured population against excessive health expenditures. This paper estimates the impact of SP on catastrophic health expenditures (CHE), as well as out-of-pocket (OOP) health expenditures, from two different sources. First, we use the SP Impact Evaluation Survey (2005-2006), and compare the instrumental variables (IV) results with the experimental benchmark. Then, we use the same IV methods with the National Health and Nutrition Survey (ENSANUT 2006). We estimate naïve models, assuming exogeneity, and contrast them with IV models that take advantage of the specific SP implementation mechanisms for identification. The IV models estimated included two-stage least squares (2SLS), bivariate probit, and two-stage residual inclusion (2SRI) models. Instrumental variables estimates resulted in comparable estimates against the "gold standard." Instrumental variables estimates indicate a reduction of 54% in catastrophic expenditures at the national level. SP beneficiaries also had lower expenditures on outpatient and medicine expenditures. The selection-corrected protective effect is found not only in the limited experimental dataset, but also at the national level.

Diabetes treatment and control: the effect of public health insurance for the poor in Mexico

OBJECTIVE

To analyse the effect of enrolment in the public health insurance scheme known as Seguro Popular [People's Insurance] on access to health resources, treatment and blood glucose control among poor adults with diabetes in Mexico.

METHODS

We analysed cross-sectional data from the 2006 National Health and Nutrition Survey and compared health care access and biological health outcomes, specifically glycosylated haemoglobin (HbA1c) levels, among adults with diabetes who were enrolled in the Seguro Popular (treatment group) and those who had no health insurance (control group). Standard propensity score matching was used to create a highly comparable control group.

FINDINGS

Adults with diabetes who were enrolled in the Seguro Popular had significantly more access than comparable uninsured adults to some type of blood glucose control test (by a difference of 9.5 percentage points; 95% confidence interval, CI: 2.4-16.6) and to insulin injections (3.13 more per week; 95% CI: 0.04-6.22). Those with insurance were also significantly more likely to have appropriately-controlled blood glucose levels (HbA1c 12%) was found in a significantly smaller proportion of adults in the insured group than in the uninsured group (by a difference of 17.5 percentage points; 95% CI: 6.5-28.5).

CONCLUSION

The Seguro Popular appears to have improved access to health care and blood glucose control among poor adults with diabetes in Mexico, and it may have had a positive effect on the management of other chronic health conditions, but its long-term effects are yet to be demonstrated. Although the findings are most relevant to Mexico, they may also be applicable to other developing countries seeking to improve health-care coverage for the poor by expanding their public health insurance programmes.

Heterogeneous impact of the "Seguro Popular" program on the utilization of obstetrical services in Mexico, 2001-2006: a multinomial probit model with a discrete endogenous variable

OBJECTIVE

We evaluated the impact of Seguro Popular (SP), a program introduced in 2001 in Mexico primarily to finance health care for the poor. We focused on the effect of household enrollment in SP on pregnant women's access to obstetrical services, an important outcome measure of both maternal and infant health.

DATA

We relied upon data from the cross-sectional 2006 National Health and Nutrition Survey (ENSANUT) in Mexico. We analyzed the responses of 3890 women who delivered babies during 2001-2006 and whose households lacked employer-based health care coverage.

METHODS

We formulated a multinomial probit model that distinguished between three mutually exclusive sites for delivering a baby: a health unit specifically accredited by SP; a non-SP-accredited clinic run by the Department of Health (Secretaría de Salud, or SSA); and private obstetrical care. Our model accounted for the endogeneity of the household's binary decision to enroll in the SP program.

RESULTS

Women in households that participated in the SP program had a much stronger preference for having a baby in a SP-sponsored unit rather than paying out of pocket for a private delivery. At the same time, participation in SP was associated with a stronger preference for delivering in the private sector rather than at a state-run SSA clinic. On balance, the Seguro Popular program reduced pregnant women's attendance at an SSA clinic much more than it reduced the probability of delivering a baby in the private sector. The quantitative impact of the SP program varied with the woman's education and health, as well as the assets and location (rural vs. urban) of the household.

CONCLUSIONS

The SP program had a robust, significantly positive impact on access to obstetrical services. Our finding that women enrolled in SP switched from non-SP state-run facilities, rather than from out-of-pocket private services, is important for public policy and requires further exploration.
