What is it? Why is it important?
Participant recruitment must be diligently documented starting with:
- Pre-Screening: a list generated by Site-INVs and based on patient chart reviews, listing potential study participants to be approached for the study
- Screening Log: a list of all participants screened for study eligibility
- Enrolment Log: a list of recruited participants fulfilling inclusion criteria with none of the exclusion criteria
- Identification Log: a list that matches participant study ID with personal details (name, date of birth)
Screening and Enrolment log can be in a combined document.
What do I need to do?
Document participant recruitment on an ongoing basis.
The date of participant consent is recorded in:
- SD (e.g. participant medical record, study worksheets, etc.)
- The study specific CRF (pCRF) and electronically in the database (eCRF)
The consent date is the official study starting point for participants as:
- They become officially recorded as study participants
- Study relevant procedures can be implemented
- Participant compliance becomes essential
- Collected data is recorded
- Safety documentation and reporting becomes mandatory
- The study becomes liable regarding insurance claims
For more information refer to Documents in this Study Guide.
Maintain ongoing surveillance regarding recruitment progress. Potential countermeasures might become necessary in the event that:
- Recruitment is slower than expected
- Number of eligible patients is low
- Participant drop-out is high
