The Effectiveness of Small-Group Community-Based Information Sessions on Clinical Trial Recruitment for Secondary Prevention of Alzheimer's Disease

While recruiting for the Anti-Amyloid Treatment in Asymptomatic Disease (A4) Trial, investigators compared one-on-one with small-group recruitment sessions. Of the 127 potential participants, most chose small-group sessions. Researchers found that small-group sessions yielded a recruitment rate of 90 percent, while one-on-one sessions led to a 67 percent recruitment rate. In addition, small-group sessions contributed to significantly shorter median time for consent processes (20 versus 60 minutes) and reduced staff time spent on persons not recruited. The authors concluded that small-group education programs are an effective strategy for enhancing recruitment success and facilitating practical recruitment into clinical trials with high recruitment demands.
