Health expenditures in Latin America and the Caribbean

Does Education Mitigate the Effect of Population Aging on Health Expenditure? A Panel Data Study of Latin American Countries

Objective: To examine whether the effect of population aging on healthcare expenditures as a share of Gross Domestic Product (GDP) is attenuated in more educated countries. Method: The analysis is based on a dataset of 22 Latin American countries between 1995 and 2013. We estimate panel data models with country and time fixed effects, and control for potential nonlinear effects of population aging on health expenditure. Results: We find population aging increases health expenditure as a share of GDP in economies characterized by low levels of education, but this effect is mitigated in economies with higher levels of education. Results are driven by private health expenditures. Discussion: Results suggest population aging and education have a stronger influence on healthcare expenditures in less developed countries. This finding is important in a context in which the rapid growth of the aging population is likely to lead to significant costs in terms of health expenditures, but less so in more educated societies.

Dermatoses of the Caribbean: Burden of skin disease and associated socioeconomic status in the Caribbean

Introduction

Dermatologic disease represents a significant burden worldwide, but the regional effect of skin disease in the Caribbean and how it relates to socioeconomic status remain unknown.

Objective

This study aims to measure the burden of skin disease in the Caribbean from epidemiologic and socioeconomic standpoints.

Methods

We selected Global Burden of Disease Study data sets to analyze disability-adjusted life-years (DALYs) and the annual rate of change of dermatoses between 1990 and 2017 in 18 Caribbean countries and the United States. The principal country-level economic factor used was gross domestic product per capita from the World Bank.

Results

Countries with lower gross domestic product per capita had higher DALYs for dermatology-related infectious diseases, urticaria, asthma, and atopic dermatitis. Countries with higher gross domestic product per capita had higher DALYs of cutaneous neoplasms, contact dermatitis, psoriasis, and pruritus. Several Caribbean countries were among the top worldwide for annual increase in DALYs for melanoma, nonmelanoma skin cancers, bacterial skin disease, and total skin and subcutaneous diseases.

Conclusion

Despite promising ongoing interventions in skin disease, better support is needed in both resource-rich and -poor areas of the Caribbean. DALYs can serve as a purposeful measure for directing resources and care to improve the burden of skin disease in the Caribbean.

Primary care in Caribbean Small Island Developing States

Caribbean Small Island Developing States (SIDS) made good process on improving the health of their populations; but concerns exist when it comes to meeting changing health needs. Due to remoteness and limited resources it is difficult to respond to high rates of non-communicable diseases (NCDs). Furthermore, little is known about how primary care (PC) is organised and how this responds to current health issues. This study focused on gaining insights in the organisation of PC of Caribbean SIDS based on currently available literature. This literature review was an explorative multiple case study, where structure of PC and health status of 16 Caribbean SIDS were reviewed using available scientific and grey literature between the years 1997 and 2014. Thirty documents were used to analyse 20 indicators for the dimensions “Structure of Primary Care” and “Health Status”. Results were mapped in order to identify if there is a possible relation between structures of PC to the health of the populations. When reviewing the structure of PC, the majority of information was available for “Economic conditions of PC” (78%) and the least information was available for “Governance of PC” (40%). With regards to health status, all islands show improvements on “Life expectancy at birth” since 2007. In contrast, on average, the mortality due to NCDs did not improve. Saint Lucia performs best on “Structure of PC”. The British Virgin Islands have the best health status. When both dimensions were analysed, Saint Lucia performs best. There is still little known on the responsiveness of PC of Caribbean SIDS to NCDs. There is a need for elaborate research on: (1) If and how the functioning of these health systems relate to the health status; (2) What islands can learn from an analysis over time and what they can learn from cross-island analysis; and (3) Filling the gaps of knowledge which currently exist within this field of research.

Comparison of the effects of public and private health expenditures on the health status: a panel data analysis in eastern mediterranean countries

BACKGROUND

Health expenditures are divided in two parts of public and private health expenditures. Public health expenditures contain social security spending, taxing to private and public sectors, and foreign resources like loans and subventions. On the other hand, private health expenditures contain out of pocket expenditures and private insurances. Each of these has different effects on the health status. The present study aims to compare the effects of these expenditures on health in Eastern Mediterranean Region (EMR).

METHODS

In this study, infant mortality rate was considered as an indicator of health status. We estimated the model using the panel data of EMR countries between 1995 and 2010. First, we used Pesaran CD test followed by Pesaran's CADF unit root test. After the confirmation of having unit root, we used Westerlund panel cointegration test and found that the model was cointegrated and then after using Hausman and Breusch-Pagan tests, we estimated the model using the random effects.

RESULTS

The results showed that the public health expenditures had a strong negative relationship with infant mortality rate. However, a positive relationship was found between the private health expenditures and infant mortality rate (IMR). The relationship for public health expenditures was significant, but for private health expenditures was not.

CONCLUSION

The study findings showed that the public health expenditures in the EMR countries improved health outcome, while the private health expenditures did not have any significant relationship with health status, so often increasing the public health expenditures leads to reduce IMR. But this relationship was not significant because of contradictory effects for poor and wealthy peoples.

Oral cleft prevention program (OCPP)

Background

Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted.

Methods/design

This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P), on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P) randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg) to that of a historical control group.

The study has been approved by IRBs (ethics committees) of all involved sites. Results will be disseminated through publications and presentations at scientific meetings.

Discussion

The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study provides an opportunity for huge savings in not only money but the overall quality of life. This may help establish more specific clinical guidelines for oral cleft prevention so that the intervention can be better tailored for at-risk women.

Different neurological conditions between urban and rural samples from central Colombia

OBJECTIVES

Despite availability of neuroepidemiological data, urban-rural differences on neurological diseases have almost never been considered. Our goal is to identify differences in the frequency of neurological conditions between a rural and an urban sample from central Colombia.

METHODS

We compared frequencies of neurological encounters of an urban sample from Bogotá (N=2932), to our rural sample from Tunja (N=2664), collected both circa to 2000. The classification of neurological conditions used is based on the 9th revision of the International Classification of Diseases, clinical modification. A clustered sampling was used. Information collection was performed in a format designed for this purpose and already used in Colombia.

RESULTS

Highly significant statistical differences (p<0.0001) were found for cerebrovascular diseases, seizure disorder, headache, Parkinson's disease and other movement disorders, and, inflammatory (infectious) conditions. Neurodevelopmental disorders (p=0.0029), dizziness and balance problems (p=0.0018), and neuropathies (p=0.0007), also showed statistically significant differences.

CONCLUSIONS

Our study showed significant differences on all categories and diagnostics between the samples. Cerebrovascular disease the most frequent reason of neurological consultation in the rural sample could be confounded by sociodemographic (aging of the population, urbanization process), or the concomitant presence of medical (chronic pulmonary) and/or environmental (air pollution) conditions.

Public versus private treatment of chronic diseases in seniors: Argentina, Brazil, Chile and Uruguay

This article measures differences in the likelihood of treatment of chronic diseases in elders across types of coverage (private, public and social security) in four major Latin American cities: Buenos Aires (Argentina), Sao Paulo (Brazil), Santiago (Chile) and Montevideo (Uruguay). We used a logistic regression to estimate the odds ratio for treatment of chronic diseases carried by individuals with public, private and social security coverage. The data were from the Survey on health, well-being and aging in Latin America and the Caribbean (SABE) conducted in 1999 and 2000. We find a strong association between possession of public coverage only and treatment failure of chronic diseases in elders in Argentina. We find no significant association for Brazil, Chile and Uruguay. In Buenos Aires, access to private or social security coverage is a necessity for elders because the public sector fails to provide proper treatment. In the remaining cities, private or social security coverage provides similar coverage for chronic diseases in elders compared with the public sector. For this group of countries, the main difference between the former and the latter seems to be in terms of 'luxurious' characteristics, such as the quality of the facilities and waiting times.

Universal health coverage and litigation in Latin America

PURPOSE

Over the last five years many middle-income Latin American countries have seen a steep increase in the number of cases litigating access to curative services. The purpose of this paper is to explore this complex phenomenon and outline some of its roots and impacts.

DESIGN/METHODOLOGY/APPROACH

The authors use an interdisciplinary approach based on a literature review and workshops convened to discuss the issue.

FINDINGS

A range of reasons can explain this increased legal activity. These include: a renewed judicial approach to the enforcement of the right to health; a more demanding public interest; an increased prevalence of non communicable diseases; and limited capacity for fair benefit package.

ORIGINALITY/VALUE

The findings in this paper argue for the need to incorporate a rights-based approach to health policy as a foundation of societal efforts to achieve universal health coverage in Latin America.

Finding affordable health workforce targets in low-income nations

To raise the awareness of a global crisis in human resources for health care, the World Health Organization has suggested a minimum target for all countries: 2.3 health professionals per 1,000 people. Many countries cannot afford to meet the target; in fact, funding the proposed number of health workers would require some countries to devote 50 percent of their gross domestic product to health. We offer an alternative solution that would allow governments to set targets that are realistic and achievable within their financial constraints.

Application of neurodevelopmental screening to a sample of South American infants: the Bayley Infant Neurodevelopmental Screener (BINS)

OBJECTIVE

To evaluate the utility of the Bayley Infant Neurodevelopmental Screener (BINS), standardized in the US, for South American infants, 3-24 months of age.

METHODS

Thirty-five physicians administered the BINS to 2471 South American infants recruited during routine well-child visits, 578 (23%) from Brazil and 1893 (77%) from six other South American countries. The BINS was translated into Spanish and Portuguese and participating physicians were trained to administer the BINS. Physician inter-rater agreement with training tapes was 84.4%; test-retest reliability for age item sets ranged from 0.80 to 0.93 (Pearson's r). Infants were classified into being at low, moderate, or high risk for developmental delay or neurological impairment based on their total BINS score. The sample was stratified by infant's age, sex and language (Spanish and Portuguese). The BINS scores were compared to the scores of the US infant sample used to standardize the BINS.

RESULTS

Female infants performed higher than male at 16-20 months and 21-24 months; male infant scores were more variable at 5-6 months. Scores on only two items were significantly different between Spanish and Portuguese speaking participants. South American scores were typically significantly higher than the US sample, and a lower proportion of infants were classified as being at high risk in the South American sample than in the US standardization sample.

CONCLUSION

Overall, the results of this study indicate that the BINS is feasible and appropriate for neurodevelopmental screening in South America. Further studies are needed to confirm the BINS utility in South America, including its use with a clinical sample.

Equity and accessibility in health? Out-of-pocket expenditures on health care in middle income countries: evidence from Mexico

This study analyzes the results of a cross-sectional survey which set out to determine the costs to patients of searching for and receiving health care in public and private institutions. The information analyzed was obtained from the study population of the Mexican National Health Survey. The dependent variable was the out-of-pocket users' costs and the independent variables were the insurance conditions, type of institution and income. The empirical findings suggest that there is a need for a more detailed analysis of user costs in middle income countries in general, where the health system is based on social security, public assistance and private institutions. This study shows that the out of pocket costs faced by users are inequitable and fall disproportionately upon socially and economically marginalized populations.

Evidences on weaknesses and strengths from health financing after decentralization: lessons from Latin American countries

OBJECTIVE

The main objective was to identify trends and evidence on health financing after health care decentralization.

STUDY DESIGN

Evaluative research with a before-after design integrating qualitative and quantitative analysis. Taking into account feasibility, political and technical criteria, three Latin American countries were selected as study populations: Mexico, Nicaragua and Peru.

DATA SOURCES

The methodology had two main phases. In the first phase, the study referred to secondary sources of data and documents to obtain information about the following variables: type of decentralization implemented, source of finance, funds of financing, providers, final use of resources and mechanisms for resource allocation. In the second phase, the study referred to primary data collected in a survey of key personnel from the health sectors of each country.

FINDINGS

The trends and evidence reported in all five financing indicators may identify major weaknesses and strengths in health financing.

CONCLUSIONS

Weaknesses: a lack of human resources trained in health economics who can implement changes, a lack of financial resource independence between the local and central levels, the negative behavior of the main macro-economic variables, and the difficulty in developing new financing alternatives. Strengths: the sharing between the central level and local levels of responsibility for financing health services, the implementation of new organizational structures for the follow-up of financial changes at the local level, the development and implementation of new financial allocation mechanisms taking as a basis the efficiency and equity principles, new technique of a per-capita adjustment factor corrected at the local health needs, and the increase of financing contributions from households and local levels of government.

Child mental health in Latin America: present and future epidemiologic research

OBJECTIVE

This report reviews population studies of child and adolescent mental health carried out in Latin America over the past 15 years. Also considered is the issue of how to meet the needs of children and adolescents who may present mental health problems in Latin America, given that most of them live in poverty in economies that are underdeveloped, providing limited resources.

METHOD

Ten studies from six different countries were identified that employed some form of randomized sampling method and used standardized instruments for assessment. The authors present a summary of the main characteristics of these studies, highlighting methodological features that may account for differences in the rates obtained.

RESULTS

Overall, a similar pattern of prevalence and risk factors for mental health problems in children and adolescents in Latin American countries emerged. Moreover, rates of disorders in these children are similar to the 15 to 20% found in other countries. These findings are similar to those observed when adult mental health problems are considered. Prevention and treatment strategies are discussed and the peculiarities of the delivery of mental health services for children and adolescents are explored.

CONCLUSIONS

Future research needs to focus on understanding of resilience and formal and informal mental health delivery systems of care available in different Latin American countries. Such research has high potential for ameliorating the prevention and treatment of child and adolescent mental health problems in this region of the world.

Financing indicators for health care decentralization in Latin America: information and suggestions for health planning

This article presents the results from an evaluative longitudinal study with before-after design. The main objective was to determine the effects of health care decentralization on changes in health financing. Taking into account feasibility, political and technical criteria, three Latin American countries were selected as study populations: Mexico, Nicaragua and Peru. The methodology had two main phases. In the first phase, the study referred to secondary sources of data and documents to obtain information about the following variables: type of decentralization implemented, source of finance, funds of financing, providers, final use of resources and mechanisms for resource allocation. In the second phase, the study referred to primary data collected in a survey of key personnel from the health sectors of each country. Taking into account the changes implemented in the three countries, as well as the strengths and weaknesses of each country in financing and decentralization, a rule for decision-making is proposed that attempts to identify the main financial changes implemented in each country and the basic indicators that can be used in future years to direct the planning, assessment, adjustment and correction of health financing and decentralization.

Health financing changes in the context of health care decentralization: the case of three Latin American countries

OBJECTIVE

The results of an evaluative longitudinal study, which identified the effects of health care decentralization on health financing in Mexico, Nicaragua and Peru are presented in this article.

METHODS

The methodology had two main phases. In the first, secondary sources of data and documents were analyzed with the following variables: type of decentralization implemented, source of financing, funds for financing, providers, final use of resources, mechanisms for resource allocation. In the second phase, primary data were collected by a survey of key personnel in the health sector.

RESULTS

Results of the comparative analysis are presented, showing the changes implemented in the three countries, as well as the strengths and weaknesses of each country in matters of financing and decentralization.

CONCLUSIONS

The main financing changes implemented and quantitative trends with respect to the five financing indicators are presented as a methodological tool to implement corrections and adjustments in health financing.

Bucking the trend? Health care expenditures in low-income countries 1990-1995

Health care expenditures in low-income countries are analysed for the years 1990 and 1995 using four key indicators. Key findings include a substantial reduction in public spending per capita across low-income countries between 1990-95; a significant shift towards private expenditures, which appears increasingly to be substituting rather than supplementing public expenditures; a fall in total and public health spending in many countries despite growth in national income, contradicting the relationship found in other studies. Two possible explanations are put forward. First that the patterns found are a direct result of the structural adjustment policies adopted by many low-income countries, which aim to control and often cut public financing, whilst promoting private health expenditures. Secondly, that following the wave of privatization of state industries, many governments are finding problems adapting to their new role as a tax collector, and are thus not benefiting from economic growth to the extent that might be expected.
