If there is not a requirement to track how many people decline to participate (and why they declined), it can still be helpful for both integrating lessons learned for your future studies and for describing your process in a resulting manuscript. If you decide to track declinations, be sure to specify a process that is shared with each Research Study Team member who is recruiting and consenting. This process may include creating a document that is shared among Research Study Team members or crafting a process for members to track individually and combine records at the end of enrollment.
