What this trial studies
This interventional study compares multilingual, visually enhanced animated videos with standard consent methods to see if they improve understanding of the procedure, preparation steps, and adherence among adults scheduled for outpatient colonoscopies. Participants are 18 years or older, German-speaking, and able to participate; those with cognitive impairments or unwilling to participate are excluded. The evaluation focuses on patient comprehension and the quality of bowel preparation, aiming to reduce missed lesions and improve procedure efficiency. The study is led by Prof. Dr. Jörg Leuppi at Cantonal Hospital of Baselland in Liestal. This work builds on prior efforts to use visual tools to enhance health literacy and informed decision-making in gastrointestinal care.
Why it matters
Potential benefit: If successful, patients may achieve better understanding and adherence to prep instructions, potentially improving bowel cleanliness and procedure outcomes.
How similar studies have gone: Previous work with visual and multimedia aids in healthcare has shown improvements in comprehension and adherence, though results can vary by setting and population.
