Verified Clinical Trials (VCT) presented a poster at the ASCP meeting in Phoenix May 2019, detailing travel habits and distances specifically in CNS clinical trials. Bottom line: In many instances, research subjects travel large distances to become duplicate subjects in CNS clinical trials. A research subject database is needed to prevent duplicate subjects and many other preventable protocol violations.
Characteristics of duplicate subjects in CNS clinical trials and psychiatry trials were reviewed. Without a tool like Verified Clinical Trials, it is impossible to proactively detect and prevent duplicate subjects or over enrollment in clinical trials. A research subjects database registry promotes safety and improved data quality and is the standard of good clinical trial practice.
