    P2.11-29 - Impact of an Information-Film to Promote Informed Decision-Making in Individuals Taking Part in a Lung Cancer Screening Demonstration Pilot (ID 12757)

    • Abstract

    Background
    

    Lung cancer screening by Low Dose CT (LDCT) is underway in the United States, where a shared decision-making process is mandated for insurer funding. The potential harms of screening are complex and difficult to communicate. Participants do not always read written materials and audio-visual aids have been shown to improve informed decision-making in other areas of medicine. There are limited studies on the use of decision aids in lung cancer screening.

    A five-minute information-film was made to explain the benefits and risks of lung cancer screening. Qualitative research informed the content and format to make it accessible for individuals of varying demographic and educational backgrounds. A sub-sample of participants (n=229) from a lung cancer screening pilot were randomised to watch the film and read a written information booklet (Group A) or read the booklet alone (Group B). Objective and subjective knowledge of the risks and benefits of screening were assessed before and after the intervention, and again after discussion with a heath care professional, when decisional conflict and satisfaction were also assessed.

    120 and 109 participants were randomised to groups A and B respectively. There was a statistically significant improvement in subjective and objective knowledge scores post-administration of the intervention in both groups (p<0.001). In a multivariate analysis adjusted for educational level and baseline knowledge score, post interventional scores were independently associated with film group (p=0.036). There were no group differences in decisional conflict or satisfaction, or in subsequent attendance for LDCT. Participants’ views on the acceptability of the film are presented in table 1.

    The information-film was well-accepted and increased knowledge scores more than a written booklet alone, without raising decisional conflict or reducing attendance for LDCT.
