An educational video to increase clinical trials enrollment among lung cancer patients

J Thorac Oncol. 2008 Jan;3(1):23-9. doi: 10.1097/JTO.0b013e31815e8bb2.

Abstract

Introduction: Only 3 to 5% of new adult cancer patients participate in clinical trials nationwide. The lack of knowledge and awareness about clinical trials is a significant barrier to clinical trials participation. A randomized trial was conducted to test the effect of an educational video on positively changing patients' knowledge and attitudes regarding clinical trials and thereby increasing enrollment rates.

Methods: Lung cancer patients were randomized to viewing either an 18-minute video about clinical trials before first clinic appointment or to standard care. Participants completed a baseline and 2-week postintervention survey to assess their knowledge and attitudes toward trials participation. Fisher's exact test tests, t tests, and regression were used to compare patient characteristics and outcomes between arms.

Results: Of 145 subjects randomized, 126 (63/arm) satisfied all inclusion criteria and were included in the analysis. A linear regression showed that the video intervention was significantly associated with patients' self-assessed likelihood to enroll score measured at 2-week follow-up (p = 0.019). Although statistically insignificant, enrollment rates were found to be higher in the intervention arm for therapeutic trials alone (17.5% versus 11.1%) and for therapeutic and nontherapeutic trials combined (25.4% versus 15.9%).

Conclusions: The brief educational video seems to be effective in positively changing lung cancer patients' attitudes about participation in clinical trials. Higher enrollment rates were also observed in the intervention group but the differences did not reach statistical significance. These findings suggest a potential impact of the educational video on clinical trial enrollment; however, larger studies are needed to confirm these findings.
