The objective was to analyze the perception of the Brazilian population on the medical health care, using data from the National Health Survey, 2013. Among those who have consulted with doctor in the 12 months prior to the survey, we analyzed 12 aspects related to health services and medical consultation, according to type of care (public/ private). By multivariate logistic regression, factors associated with dissatisfaction with the care received were investigated. For the dimensionality reduction of the assessed aspects, we used principal component analysis. The survey revealed that 74.2% of the adult Brazilian population consulted a doctor. Among the differences by type of care, stood out the way of getting an appointment, the type of doctor, the waiting time for service, and the reason for consultation. Median scores were concentrated in 80 (good), except for the waiting time between SUS users. Proportions of very good evaluation were, however, higher among users of the private sector. Despite the positive evaluation in both sectors, public and private, the configuration of the Federative Units in the plane formed by the two principal component axes followed a pattern of striking regional differences.
