Portuguese Healthcare Regulation Authority (Entidade Reguladora da Saúde – ERS)

Who we are
The Portuguese Healthcare Regulation Authority (Entidade Reguladora da Saúde – ERS) is the independent public body responsible for regulating the activity of health care providers in Portugal.

Who we regulate
The scope of regulation includes all health care providers located in the mainland territory of Portugal, of public, private or social ownership, and regardless of its individual or collective nature. Currently ERS oversees close to 15,000 health care establishments. 

What we do
ERS aims at delivering independent assurance about:
  • the compliance with legal requirements for health care services and establishments,
  • the protection of health care service users rights, including access and freedom of choice,
  • the legality and transparency in the economic relations between providers, funders and users,
  • fair competition in health care markets.
How we do it
ERS carries out several regulation and supervision activities, including:
  • registering health care providers,
  • handling complaints from service users, 
  • carrying out inspections and audits to heath care providers ,
  • carrying out investigations of situations with significant adverse impact on the rights of patients or on the quality and safety of care,
  • conducting administrative offence procedures involving health care providers and applying the resulting sanctions,
  • producing studies, advice papers and recommendations.
How can we help you
If you believe that an health care provider violated your (or someone else’s) rights, you may file a complaint by:
  • asking the provider to write in the official Complaints Books, which must be made available by private and social health care providers,
  • submitting it in the Online Complaints Book that is available at www.ers.pt,
  • writing it and addressing it to ERS by postal mail or email.
