As long as the physician communicates to you why a patient was excluded, you can fill out the screening log entry without the physical CSF. The physician could let you know this retroactively via email (as long as no protected health information is included) or in person. The most important part is recording why a patient was excluded, not having the original form, as we will not be keeping the paper CSF forms for excluded patients. (The CSF functions as a “worksheet” for screening purposes. It will only be kept on file as a case report form for patients who are enrolled, in order to document their eligibility.)
