A recent survey conducted by the Organisation for Economic Co-operation and Development (OECD) highlights a significant increase in Brazilian public satisfaction with the Unified Health System (SUS). Between 2022 and 2025, the approval rating rose from 34% to 45%, showcasing a nine-point increase that places Brazil above the Latin American average satisfaction rate of 40% for the same period. This upward trend indicates a growing trust in public health services among Brazilian citizens.

The study, titled 'Trust in Public Institutions in Latin America and the Caribbean,' outlines an 18-point rise in the perception of access and quality of public services in Brazil, which increased from 24% to 42%. This is notably higher than the Latin American average, which stands at 32%. Such statistics reflect a notable improvement in how Brazilians view not only the health system but also the broader quality of governance and public service delivery during this time.

OECD officials have praised the survey as a successful initiative to assess the complex relationship between trust and democratic public governance. The methodology involved a sample of 2,000 individuals nationwide, and it evaluated several important areas, including integrity, responsiveness, reliability, openness, and equity. The results contribute to an understanding of public sentiment in Brazil and underscore the importance of continuous improvement in health services and governance for maintaining and enhancing citizen trust.
