SUS
Referral
Emergency

SUS (Brazil’s National Health System) orders that a citizen’s care must be performed according to a hierarchy of units (from basic level to high complexity) and the patient’s referral and reverse referral between them must be at the premises of the health care service that the citizen needs.

This means that the first care must be performed in the health care service of their area or the area where they currently are, such as an AMA (Outpatient Medical Care) or a regional emergency room.
