Limited evidence exists on the effectiveness of education and training interventions on trial recruitment; a systematic review

Objective: To examine the effectiveness of education and training interventions on recruitment to randomised and non-randomised trials. Study Design and Setting: A systematic review of the effectiveness of education and training interventions for recruiters to trials. The review included randomised and non-randomised controlled trials of any type of education and training intervention for recruiters to trials, within any healthcare field. The primary outcome was recruitment rates, and secondary outcomes were: quality of informed consent, recruiter self-confidence, understanding/knowledge of trial information, numbers of potential trial participants approached, satisfaction with training, retention rates. Results: Of the 19 records reviewed at full text level, six met the inclusion criteria for our review. Due to heterogeneity of outcomes and methods between the included studies, meta-analysis was not possible for the primary outcome. Of the three studies that reported recruitment rates, one favoured the education and training intervention for increased recruitment; the remaining two found no differences between the groups. Of the reported secondary outcomes, quality of informed consent was improved, but no differences between groups in understanding/knowledge of trial information were found. Conclusion: There is limited evidence of effectiveness on the impact of education and training interventions on trial recruitment. Further work on developing a substantial evidence base around the effectiveness of education and training interventions for recruiters to trials is required.
