What is it? Why is it important?
Site feasibility (SF) indicates whether a potential study site is suitable to participate in a planned study.
SF checks include, but are not limited to an analysis of:
- Interest in study participation
- Sufficient time to invest in a study
- Not active in any competing studies
- Experience in conducting similar types of studies
- A SF check should address all aspects pertaining to the successful conduct of a study.
- Taking time to assess feasibility is an important investment because it avoids problems that potentially could have been prevented.
- Managing problems during study implementation and conduct will delay and most likely require additional resources and funding.
Some aspects may require more detailed investigations. An example would be the handling and storing of biological samples:
- Does the site have access to freezers at the required temperature (e.g. −80°C)?
- How are freezer access rights managed?
- How is freezer temperature monitored?
- Are there emergency procedures installed in the event of freezer failure?
- Are there adequate sample shipment procedures?
What do I need to do?
Depending on how you plan to set up your study, you need to:
- Define study relevant feasibility questions
- If applicable, add questions addressing issues from your past experiences or lessons learned from previous similar studies
- Leave space for the Site-INV to include questions, comments, and suggestions
Writing a feasibility questionnaire can be quite challenging because not all eventualities can be predicted. Some aspects may only become apparent during study conduct.
Explicit questions could be included in a feasibility questionnaire, such as, does the site have:
- Sufficient time and adequate resources?
- A sufficient number of participants potentially willing to participate in the study?
- Ability to adhere to required safety reporting procedures (e.g. 24-hour emergency cover)?
- Appropriate storage facilities for IMP/MD?
- Appropriate procedures for handling IMP (e.g. storage, processing, and shipment procedures)?
- A suitable QMS in place (e.g. SOPs, WIs, staff trainings, relevant processes for managing study tasks)?
- No competing studies to be conducted in parallel which would jeopardize the adequate amount of participants available for the study?
A site feasibility check can be done remotely or on-site. Nevertheless, a personal visit to the site is often advisable. Many study aspects are difficult to check remotely, such as required infrastructure and facilities.
It is always an advantage to establish a personal contact with an on-site study staff member. This makes it easier to evaluate the site, establish a robust communication line, and solve future problems.
