Trial sites (centres) must be added to the system before adding a patient or randomising, completing forms, updating a code list, or creating investigator accounts. Sites must also have their status set to either Authorised to recruit patients or Recruiting patients before patients can be added. The site number may be used in some trials to create a patient identifier of the form
SS is the site number and
NNN is a sequential number (either within or across sites).
Administrators can add sites by clicking on the Contacts link in the left-hand sidebar, followed by the New site link.
Note that sites may not be deleted once they are referenced by another record in the database (e.g. when a patient form has been completed for a patient at that site).
The contacts help contains some more information on managing contacts.
