The biggest challenge to the successful delivery of a clinical trial is recruitment.  Failure to identify appropriate individuals, to enroll them and to retain them throughout a study is not only costly, but may seriously compromise the study's power and overall scientific integrity.  This workshop is designed for all those involved in the design and conduct of clinical trials.  We will review the relevant literature relating to different recruitment methods and look at practical solutions to the problem of successful recruitment and retention.  The workshop will consist of a series of short, interactive lectures, interspersed with practical exercises.
