Background
Brazil has a highly stratified population with large socioeconomic disparities, as evidenced by marked differentiation in health status and access to health services by the population. In addition, the fact that the universal national healthcare system and a liberalised private care model exist side by side leads to increasingly inequitable health outcomes.

Aims
This study aims to appraise the equity of access to the University Hospital in Brasilia, Brazil, in 2013.

Methods
This study was a quantitative analysis of hospital admissions data. The sample included all patients admitted over a six- month period in 2013. Patient data was crossed with socioeconomic data (income and private health insurance status). Frequency tabulations and chi-square calculations were used to describe the patient mix, observe trends and appraise equity of admissions.

Results
Analysis of the data showed that the number of patients from each neighbourhood relative to the neighbourhood population was equitable. However, when assessed on the basis of insurance status (i.e., deducting the population covered by private health insurance), a high level of inequity was detected (chi-square 71.828, df 3, p
