What Do We Know About Clinical Trials?

September 01, 2004

I've recently reviewed many articles on subject recruitment, retention, and attrition in clinical trials. I have found the same three basic research methods: surveys (by telephone and in person), interviews, and focus groups. The information gathered from the three methods include demographics, willingness to participate, problems experienced in clinical trials, motivations for volunteering, health behaviors, social support, benefit expectations, and understanding of the research project. But such strategies collect only the most superficial data, so we don't know nearly as much about the clinical trial experience as we need to know.
