Abstract

Background:

The perennial challenge to cancer clinical trials is accrual. To date, the focus to improve accruals rested on addressing patient knowledge, attitudes and beliefs rooted in patient reluctance to be experimented on, financial and practical barriers and issues of mistrust. We undertook this study to describe the impact of an educational intervention to democratize recruitment and improve understanding of and information about cancer clinical trials.

Methods:

We implemented a time series intervention (INT) identifying cancer patients at treatment decision points at 3 participating Cancer Centers, educating consented breast, liver and lung cancer patients about clinical trials in general and providing clinical trial match lists to oncologists and patients prior to treatment decision-making. We defined a treatment decision point as a new, recurrent or progressing cancer. We surveyed patients and their oncologists pre- and post-intervention about their knowledge, attitudes and beliefs (KABs) of clinical trials. We compared pre & post KABs using Chi Sq and Fisher’s Exact T tests.

Results:

Of 523 consented patients at treatment decision points, 514 completed pre & 368, post-INT surveys; 60% were non-white with no racial ethnic difference in response rates (70% BIPOC v 79% White; p = 0.07). Following an educational intervention, there was no significant change in positive attitude towards clinical trials (CT): 71% pre-intervention vs 77% post-intervention; p = 0.55,…
