April 19, 2019 – A short video describing the potential benefits and risks of lung cancer screening with low-dose CT, as well as an information pamphlet, allowed patients to better know and reduce conflicts over the opportunity to submit to this badysis. , according to a randomized controlled trial published online in the newspaper Annals of the American Thoracic Society.
In "The Impact of an Information Film on Lung Cancer Screening on Informed Decision-Making: A Randomized Trial," Sam M. Janes, MBBS, Ph.D. and his Co-authors present a study of 229 participants from a London hospital who met one of three criteria used to select patients likely to benefit from screening. One of the criteria was the recommendation of the American Task Force on Prevention Services on a smoking history of 30 or more pack years in patients who quit smoking less than 15 years ago.
The authors note that studies show that less than 2% of the 7.6 million former US smokers eligible for screening actually undergo CT, while it has been shown to reduce lung cancer mortality by 20%. %.
The most significant potential damage from screening comes from the detection of nodules, or small mbades of tissue, which are generally benign, but cause anxiety and may require additional investigations or biopsies to determine whether they are cancerous or no.
Dr. Janes, lead author and director of the respiratory research department at University College London and director of London's Lung Cancer Board, said the goal of the video was to produce a tool to facilitate the conversation between patients and their doctors and shared decision-making – a requirement for reimbursement of Medicare and Medicaid in the United States
"We used feedback from other eligible patients for lung cancer screening to create an understandable film for people from different educational backgrounds and presenting information in a clear, simple and palatable manner." , he added.
The researchers used a questionnaire to measure participants' knowledge before and after reading the 10-page booklet or reading the booklet and viewing the five-and-a-half-minute video. Researchers also measured the level of conflict experienced by participants in deciding whether or not to screen.
At registration, participants answered correctly 5 out of 10 questions on average. After reading the booklet, participants in this part of the study answered seven questions correctly. After reading the booklet and viewing the video, members of this branch of the study responded correctly to eight questions.
Those who read the brochure and watched the video were more likely to correctly answer two questions than those who read the pamphlet only. The first question related to the fact that whether a lung nodule found on the CT scan is cancerous or not does not mean that there is a high risk of cancer. The second question was that the amount of radiation produced by a single scan is about the equivalent of the background radiation of a year.
Members of both groups were equally likely to be examined, with more than three in four choosing to be examined. However, those who viewed the video and read the booklet were more certain of their decision whether or not to scan. On a scale of zero to nine, their level of certainty was 8.5, compared to 8.2 for those who read only the book.
The limitations of the study include the fact that all participants were enrolled in a larger lung cancer study and that half of them would have seen the information booklet before participating in the study reported in AnnalsATS.
"There is an urgent and unmet need to provide information to people considering lung cancer screening, but to be done in a non-intimidating, user-friendly and simple way," said Mamta Ruparel, MBBS, PhD, lead author from the study and researcher at the Lungs for Living Research Center of University College London. "This study demonstrates that an information film can improve shared decision-making, while reducing conflicting feelings that patients may have to undergo the procedure without reducing participation in low-dose CT screening.
