Purpose: Radiotherapy patient education materials fail to meet readability standards, impairing access for patients with low educational attainment, disabilities, or limited-English proficiency. Design professionals and physicians developed graphic narrative discussion guides, Communication of the Gynecologic Brachytherapy Experience (CoGBE), for cylinder, intracavitary, and interstitial high-dose rate (HDR) gynecologic brachytherapy. This study assesses perceived clinical benefits, usability, and anxiety-reduction of CoGBE.

Methods: An electronic survey was sent to members of the American Brachytherapy Society. Participants were assigned to assess one of the three modality-specific CoGBE guides using a modified Systems Usability Scale (mSUS), modified state-trait anxiety index (mSTAI), and Likert-type questions. Free response data was analyzed using modified grounded theory.

Results: Median mSUS score was 76.3 (interquartile range [IQR], 71.3-82.5) and there were no significant differences between guide types. Median mSTAI was 40 (IQR, 40-43.3) for all guides collectively. The cylinder guide had a significantly higher median mSTAI than the intracavitary and interstitial guides (41.6 vs 40.0 and 40.0; p=0.04) suggesting the cylinder guide may have less impact on reducing anxiety. 72.7% rated CoGBE as “quite” or “extremely” helpful compared to a text-only pamphlet. When compared to their current education practices, 77.3% reported patients would understand “more” or “a lot more” after initial consultation and 81.8% reported CoGBE would be at least moderately helpful in making initial consultations more memorable for patients. Lastly, 79.5% reported at least a moderate likelihood of using CoGBE. Qualitative analysis themes included personalization, relatability, and graphic narrative (positive domains); generalizability and character affect (negative domains).

Conclusion: Clinicians rate CoGBE as usable with potential to reduce patient anxiety, especially with more invasive treatment modalities including intracavitary or interstitial HDR. The CoGBE guides (including multilingual versions) have global applicability, in low resource settings with high cervical cancer burdens and patient populations that may benefit from the graphic narrative format.
