Audiovisual Aids, The Effect of Audio-visual Aids on Bowel Cleanliness
Conditions
Brief summary
Effective communication in healthcare is critical for improving patient outcomes, particularly in enhancing health literacy and enabling informed decision-making. Traditional informed consent for colonoscopy often fails to clearly explain the procedure, risks, and preparation requirements, leading to inadequate bowel preparation, longer procedures, and missed lesions. Standard educational materials like videos and written instructions are often impersonal, lack cultural inclusivity, and fail to engage patients effectively. Emerging tools, such as the multilingual, visually enhanced Meine Behandlung video series from Visikon®, aim to improve patient comprehension and adherence. This study seeks to compare the effectiveness of these animated videos against traditional consent methods in enhancing patient understanding and adherence, particularly for complex procedures like colonoscopy, which is crucial for diagnosing and preventing colorectal cancer.
Interventions
BEHAVIORALAnimated Video Group 1
The animated video intervention provides a clear and engaging multimedia explanation of the colonoscopy procedure in multiple languages. It includes visual aids to help explain the process, preparation instructions, risks, and expected outcomes, aiming to improve patient comprehension and adherence.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bowel Preperation | 24 months | The objective of assessing the primary endpoint the patient's bowel cleanliness, will be measured during the routine colonoscopy, using the Boston Bowel Preperation Scale. The Boston Bowel Preparation Scale (BBPS) is a validated tool used to assess the cleanliness of the colon during a colonoscopy, Each of the three segments of the colon (right, transverse, and left) is assigned a score ranging from 0 to 3, with the following criteria: Total Score 0: The entire colon is unprepared, and no mucosa is visible. Total Score 1-3: Poor preparation, significant portions of the mucosa are not visible. Total Score 4-6: Fair preparation, with some portions of the mucosa visible but others obscured. Total Score 7-9: Good to excellent preparation, with most or all mucosa well visualized. Interpretation Scores of 0-3: Generally considered inadequate for proper assessment and diagnosis, likely requiring repeat preparation and examination. Scores of 4-6: Indicative of suboptimal preparation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Health Literacy & Communication Satisfaction | 24 months | The secondary outcome seeks to assess the patient's health literacy and general communication satisfaction. This will be done by assessing their answers to the Health Literacy Questionnaire. |
