Monitoring financial healthcare protection in Brazil: evolution, inequalities, and associated factors

Objectives

Although catastrophic health spending is the main measure for assessing financial healthcare protection, it varies considerably in methodological and empirical terms, which hinders comparison between studies. The aim of this study was to measure the prevalence of catastrophic health spending in Brazil in 2003, 2009, and 2018, its associated factors, and disparities in prevalence distribution according to socioeconomic status.

Study design

This was a time series study.

Methods

Data from the Household Budget Surveys were used. Prevalence of catastrophic health spending was measured as a percentage of the budget and ability to pay, considering thresholds of 10, 25, and 40%. It was determined whether household, family, and household head characteristics influence the likelihood of incurring catastrophic health spending. Households were stratified by income deciles, consumption, and wealth score.

Results

There was an increase in prevalence of catastrophic health spending between 2003 and 2009 in Brazil and a slight reduction in 2018. The wealth score showed more pronounced distributional effects between the poor and the rich, with the former being the most affected by catastrophic health spending. Consumption showed greater percentage variations in the prevalence of catastrophic health spending. The prevalence of catastrophic health spending was positively associated with the presence of older adults, age and female household head, rural area, receipt of government benefits, and some degree of food insecurity.

Conclusions

The poorest families are most affected by catastrophic health spending in Brazil, requiring more effective and equitable policies to mitigate financial risk.
