Hi I'm looking for advice how volunteers who attend the screening visit but decide not to consent (before being seen by the Physician) should be handled? Should they still go through the consent process and indicate on the ICF they do not wish to take part in the trial or would they be allowed to leave the site? Also are they still eligible to receive the screening compensation?

If allowed to leave, should their attendance be documented anywhere? Screening/Enrollment Log etc?

Another question is for volunteers who are obviously not within inclusion/exclusion criteria, for example clearly not within the protocol required age range but did not disclose the information at the recruitment stage.
Are they entitled to screening compensation? Should they still be consented and subsequently screen failed?
