IGAS is the Inspectorate-General for Health Activities (Inspeção-Geral das Atividades em Saúde or IGAS), the government body that inspects and audits public and private health services, investigates complaints and can recommend sanctions or changes. After reported failures in emergency care, IGAS can open inquiries, publish findings and advise the Ministry or the SNS on corrective measures; residents and patients can also file complaints that IGAS may investigate.
