SIGA SNS

Sistema Integrado de Gestão do Acesso — integrated system for managing access to care
The government system that holds SNS waiting lists: your doctor enters a specialist referral or the need for surgery into it, and the guaranteed maximum waiting times (TMRG) are counted from that entry. It is also how you are transferred to another provider if yours can't see you in time.
Where you come across it. A referral to a specialist; being put on the waiting list for surgery.
The clock does not start until the referral is registered in SIGA SNS. If you have heard nothing after the appointment, ask at reception whether the referral has been entered and on what date.
