Is primary health care worth it in the long run? Evidence from Brazil.

This paper assesses whether Brazilian primary health care is worth it in the long-run by estimating the accumulated costs and benefits of its flagship, the Family Health Strategy program (ESF). We employ an alternative strategy centered on years of exposure to the program to incorporate its dynamics. We also account for the program's heterogeneity with respect to the remuneration of ESF health teams and the intensity of coverage across Brazilian municipalities, measure by the number of people assisted by each ESF team, on average. To address heterogeneity in professional earnings, this paper employs, for the first time, a dataset containing the remuneration of professionals allocated to all ESF teams nationwide. The benefits are measured by the avoided deaths and hospitalizations due to causes sensitive to primary care. Results suggest that the net monetary benefit of the program is positive on average, with an optimum time of exposure of approximately 16 years. Significant heterogeneities in cost-benefit results were found since costs outweigh benefits in localities where the coverage is low intensive. On the other hand, the benefits outweigh the costs by 22.5% on average in municipalities with high intensive coverage.

The Brazilian Family Health Strategy and adult health: Evidence from individual and local data for metropolitan areas.

Previous studies have found that the expansion of primary health care in Brazil following the country-wide family health strategy (ESF), one of the largest primary care programs in the world, has improved health outcomes. However, these studies have relied either on aggregate data or on limited individual data, with no fine-grained information available concerning household participation in the ESF or local supply of ESF services, which represent crucial aspects for analytical and policy purposes. This study analyzes the relationship between the ESF and health outcomes for the adult population in metropolitan areas in Brazil. We investigate this relationship through two linked dimensions of the ESF: the program's local supply of health teams and ESF household registration. In contrast with previous studies focusing on comparisons between certain definitions of "treated" versus "nontreated" populations, our results indicate that the local density of health teams is important to the observed effects of the ESF on adult health. We also find evidence consistent with the presence of positive primary health care spillovers to people not registered with the ESF. However, current ESF coverage levels in metropolitan areas have limited ability to address prevailing health inequalities. Our analysis suggests that the local intensity of ESF coverage should be a key consideration for evaluations and policy efforts related to future ESF expansion.

Assessment of the association between the Brazilian family health strategy and adult mortality.

This study aimed to analyse a wide range of related health problems that respond favourably to efficient primary care treatment among adults. We evaluate the direct impact of the Family Health Strategy (ESF) in Brazil on mortality of adults aged 25-64 years related to conditions for which access to effective primary care can reduce the likelihood of more severe outcomes. Additionally, we discuss heterogeneous effects associated with different intensities of the programme. To address these issues, we estimated a model with variation at the municipal level of the ESF expansion, including municipal-fixed effects, municipal specific trends and year-fixed effects. Our results show that a higher intensity of ESF is associated with reduced mortality by all conditions sensitive to primary care and for some diseases, especially after some years: avoidable conditions, asthma, heart failure, cerebrovascular diseases and gastrointestinal ulcer, infectious gastroenteritis and complications, diseases of the lower airways, hypertension and diabetes. As a public policy view, these results help understand how a nationwide primary care strategy can help mitigate mortality and emphasize the role of having sufficient health teams to attend to the population.

Primary care coverage and individual health: evidence from a likelihood model using biomarkers in Brazil.

BACKGROUND: Although the use of biomarkers to assess health outcomes has recently gained momentum, literature is still scarce for low- to middle-income countries. This paper explores the relationship between primary care coverage and individual health in Brazil using a dataset of blood-based biomarkers collected by the Brazilian National Health Survey. Both survey data and laboratory results were crossed with coverage data from the Family Health Strategy (ESF) program, the most important primary care program in Brazil; the coverage measures aim to capture both direct (household) and indirect (spill-over) effects. METHODS: The empirical strategy used a probit model to estimate the relationship between ESF program coverage and the likelihood of abnormal biomarker levels while controlling for a rich set of individual and household characteristics based on data from the national survey. RESULTS: Household ESF coverage was associated with a lower likelihood of abnormal results for biomarkers related to anemia (marginal effect between - 2.16 and - 2.18 percentage points), kidney failure (between - 1.01 and - 1.19 p.p.), and arterial hypertension (between - 1.48 and - 1.64 p.p). The likelihood of abnormal levels of white blood cells and thrombocytes was negatively related to primary care coverage (marginal effect between - 1.8 and - 2 p.p.). The spillover effects were relevant for kidney failure and arterial hypertension, depending on the regional level. Although not sensitive to household coverage, diabetes mellitus was negatively associated with the state supply of primary care, and abnormal cholesterol levels did not present any relationship with ESF program coverage. CONCLUSIONS: The presence of spillover effects of ESF program coverage regarding these conditions reveals that the strengthening of primary care by increasing the household registration and the regional density of ESF teams is an efficient strategy to address important comorbidities.

Consumo de serviços médicos e marco regulatório no mercado de seguro de saúde brasileiro / Consumption of medical services and the regulatory framework in the Brazilian market for health insurance

O objetivo deste artigo é investigar se a Lei no 9.656/1998, que estabeleceu um novo marco regulatório do mercado brasileiro de seguro privado de saúde, afetou o comportamento dos portadores de seguros/planos privados de saúde em relação ao consumo de bens de saúde. Em termos mais específicos, investigamos se houve aumento do consumo de bens médicos, o que poderia sugerir intensificação do comportamento de risco moral, uma vez que a lei estabeleceu garantias mínimas aos segurados. A literatura sobre o tema apresenta evidências de sólida conexão entre risco moral e consumo de serviços médicos por segurados de saúde. Sob a hipótese de que a aprovação da nova lei representa um evento exógeno, o uso do estimador de diferenças-em-diferenças (DD) permite investigar se houve mudança de comportamento dos segurados em relação ao consumo de serviços médicos. Para esta finalidade, foram utilizadas as Pesquisas Nacionais por Amostra de Domicílios (PNADs) de 1998 e 2003, que contêm informações suplementares de saúde. Dois resultados principais são evidenciados: por um lado, verifica-se que os segurados consomem uma quantidade maior de bens médicos que os não segurados nos intervalos de tempo investigados, em conformidade com a literatura; por outro, a nova legislação teve efeito nulo sobre o consumo de serviços médicos
