From income inequality to social inequity: impact on health levels in an international efficiency comparison panel

Abstract

Background Health equity, although addressed in several publications dealing with health efficiency analysis, is not easily translated into the operationalization of variables, mainly due to technical difficulties. Some studies provide evidence that it does not influence health outcomes; others demonstrate that its effect is an indirect one, with the hegemony of material living conditions over its social connotation. The aim of this article is to evaluate the role of health equity in determining health outcomes, in an international comparative analysis of the effectiveness and efficiency of health systems. Method Fixed Effects Model Panel and Data Envelopment Analysis, a dynamic and network model, in addition to comparative analysis between methods and health impacts. The effect variables considered in the study were life expectancy at birth and infant mortality, in 2010 and 2015, according to the sociocultural regions of the selected countries. Inequity was assessed both economically and socially. The following dimensions were considered: physical and financial resources, health production (access, coverage and prevention) and intersectoral variables: demographic, socioeconomic, governance and health risks. Results Both methods demonstrated that countries with higher inequity levels (regarding income, education and health dimensions), associated or not with poverty, are the least efficient, not reaching the potential for effective health outcomes. The outcome life expectancy at birth exhibited, in the final model, the following variables: social inequity and per capita health expenditure. The outcome infant mortality comprehended the level of education variable, in association with the following healthcare variabels: care seeking due to diarrhea in children under five, births attended by skilled health professionals and the reduction in the incidence of HIV. Conclusion The dissociation between the distribution of health outcomes and the overall level of health of the population characterizes a devastating political choice for society, as it is associated with high levels of segregation, disrespect and violence from within. Countries should prioritize health equity, adding value to its resources, since health inequties affect society altogether, generating mistrust and reduced social cohesion.

Efficiency Analysis in Brazil’s Sao Paulo State Local Unified Health System (SUS): From Gender-Ethnicity-Power Inequities to the Dissolution of Health Effectiveness

“…This is a more structural variable than simple income differences [ 4 ], such as Theil’s indexes tested, overall and work-related income. It is noteworthy that intersectional equity did not achieve the same importance in our previous analysis of efficiency at the global level [ 31 ], which allows us to assume that the local level is the ideal locus for these differences to gain visibility.…”

“…We are interested in a link between socioeconomic inequality and objective well-being conditions between communities. [10] draw parallels between socioeconomic inequity and health outcomes, measured as infant mortality and life expectancy at birth. This analysis was conducted at the country aggregation level, and connected “health production (access, coverage and prevention) and intersectoral variables: demographic, socioeconomic, governance and health risks”.…”
