Participant verification: Prevention of co‑enrolment in clinical trials in South Africa
Abstract
Aim. To report the development and feasibility of a digital, fingerprint-based participant identification method to prevent co-enrolment at multiple clinical trial sites.
Methods. The Medical Research Council (MRC) HIV Prevention Research Unit (HPRU) developed the Biometric Co-enrolment Prevention System (BCEPS), which uses fingerprint-based biometric technology to identify participants. A trial website was used to determine the robustness and usability of the system. After successful testing, the BCEPS was piloted in July 2010 across 7 HPRU clinical research sites. The BCEPS was pre-loaded with study names and clinical trial sites, with new participant information loaded at first visit to a trial site.
Results. We successfully implemented the BCEPS at the 7 HPRU sites. Using the BCEPS, we performed real-time ‘flagging’ of women who were already enrolled in another study as they entered a trial at an HPRU site and, where necessary, excluded them from participation on site.
Conclusion. This system has promise in reducing co-enrolment in clinical trials and represents a valuable tool for future implementation by all groups conducting trials. The MRC is currently co-ordinating this effort with clinical trial sites nationally.
