Abstract
This study aims to assess the efficacy of a radiation therapy (RT) education video for patients referred for treatment. The investigators produced a 23-min guide to radiation therapy DVD, combining didactic material and patient narratives. Patients (n = 32) had not yet received their initial consultation. Baseline awareness about cancer and treatment was assessed by surveys including the rapid estimate of adult literacy in medicine. Knowledge about RT was assessed before and after viewing the video with a separate 21 question survey. Differences in benefit for sociodemographic subgroups including age, gender, ethnicity, income, education, and health literacy level were explored. Baseline assessments identified 78 % of patients regardless of sociodemographic status had “little” to “no” basic knowledge of RT. The mean number of correct responses in the 21 question survey assessing how RT works improved from 9.8 to 11.1 after watching the video (p < 0.0001; 95 % CI: 1.3–3.0), a statistically significant benefit that was present among all sociodemographic subgroups, but more prominent among those with a greater than high school education (p = 0.002). Patient satisfaction with the video was high. Knowledge among cancer patients regarding RT is poor, regardless of sociodemographic factors. This pilot study demonstrates the utility of a brief video to universally improve patient awareness about RT. While patients may ultimately learn about RT during their course of treatment, we advocate for any tools that can improve patient knowledge at the time of initial consultation as this is typically the time they are asked to acknowledge informed consent for treatment.
