Does Modification to the Approach to Contacting Potential Participants Improve Recruitment to Clinical Trials?
In this article, researchers explored two different approaches during a 6-month process of recruiting 212 individuals to an observational study. For the first 3 months, prospective participants received a phone call in which a member of the research team explained the study and invited them to participate. These participants received an information sheet by mail, and the study was re-addressed at the patient’s clinic appointment, at which the patient was formally invited to participate. In the second 3 months of recruitment, participants were invited to join the study by mail and they were first spoken to by a study investigator in the clinic, when they were formally invited to participate. Researchers found a significant improvement in recruitment rate among participants that had been in phone contact with researchers prior to clinic attendance, compared with participants who did not receive an initial phone call.
