Successful recruitment and retention are determined by the patient’s understanding and acceptance of the study protocol. Therefore, we survey potential volunteers and ask whether they would meet the major inclusion and exclusion criteria of your protocol, and we ask them if they would participate in your trial in the context of a given treatment plan. Patient survey results provide you with valuable insights in the population’s general eligibility and willingness to participate in your trial. The data can be used to fine-tune your protocol and increase the quality of your enrollment plan.
