Abstract
OBJECTIVE: Lung cancer screening (LCS) with low dose computed tomography can reduce lung cancer mortality. However, awareness and knowledge of LCS are low. We developed and tested a video to support informed decision-making about LCS for use in diverse populations, including adults with low educational attainment. METHODS: We conducted a prospective pre-post pilot study of adults eligible for LCS at three primary care clinics in the USA from 08/2022-07/2023. We developed a brief digital video, incorporating iterative modifications using participant feedback. We assessed knowledge of LCS before and after viewing the video and solicited open-ended feedback on video format and content. RESULTS: The study included 29 adults (median [range] age, 62 [50-77] years; 52 % male). In interviews, participants commented on informational content, effect of the video on screening behaviors and intent, video style and appearance, and video features. After viewing the video, participant knowledge scores increased from baseline of 43 % correct to 59 %, p < 0.001. Knowledge scores increased across all levels of educational attainment. CONCLUSIONS: A brief digital video about LCS, developed with feedback from end users, was motivating, clear, and effective in increasing knowledge across levels of educational attainment. INNOVATION: Using a patient-engaged, theoretically grounded development process, we developed a digital tool specifically to support lung cancer screening in diverse populations, including those with varied educational attainment.
