About this trial
This study will evaluate whether a digital-supported informed consent process improves patient understanding before advanced therapeutic endoscopy procedures.
Patients undergoing advanced therapeutic endoscopy are often asked to make decisions about procedures that may be complex and involve important risks, benefits, and alternatives. Standard informed consent is usually provided through discussion with the treating physician. However, this process can vary between clinicians and may be affected by time pressures in busy endoscopy units.
In this study, eligible adult patients scheduled for elective advanced therapeutic endoscopy will be randomly assigned to one of two consent pathways. One group will receive standard physician-led informed consent. The other group will receive a digital-supported consent pathway that includes a standardized procedure-specific educational video, an offline artificial intelligence-based question-answering tool, and final confirmation with the treating physician before the procedure.
The digital tool is designed to provide plain-language information about the procedure, including why it is being done, expected benefits, common and serious risks, alternatives, what to expect before and after the procedure, and the patient's right to ask questions or decline the procedure. The AI question-answering tool will use only investigator-approved educational content and will not provide individualized medical advice. Questions requiring patient-specific medical judgment will be directed back to the treating clinical team.
The main outcome of the study is patient comprehension of the consent information, measured after the assigned consent process and before the procedure. The study will also evaluate patient anxiety, satisfaction, confidence in decision-making, usability of the consent process, workflow outcomes, and consent-related safety or ethical concerns.

Treatments tested in this trial
Digital-Supported Informed Consent Pathway
BehavioralThe digital-supported informed consent pathway consists of a standardized procedure-specific educational video, an offline AI-based question-answering interface, and final physician confirmation. The video explains the nature of the procedure, indication, expected benefits, major and common risks, alternatives, what to expect before and after the procedure, and the patient's right to ask questions or decline. The AI tool provides plain-language responses based only on investigator-approved educational materials and redirects individualized or high-risk questions to the treating clinical team.
Standard Physician-Led Informed Consent
BehavioralThe standard physician-led informed consent process consists of usual pre-procedure counseling by the treating physician according to local clinical practice. The physician discusses the procedure, indication, expected benefits, risks, alternatives, and patient questions, and completes standard institutional procedural consent documentation before the advanced therapeutic endoscopy procedure.
Treatment groups
Trial outcomes
Primary outcomes
Patient Comprehension of Informed Consent Information
Patient comprehension will be assessed using a structured procedure-specific comprehension instrument after the assigned consent pathway. The instrument will assess understanding of the nature of the procedure, purpose or indication, risks, benefits, alternatives, right to ask questions or refuse, and expectations before and after the procedure.
Secondary outcomes
Pre-Procedural Anxiety
Participant-reported anxiety after completion of the assigned consent pathway, assessed using a study questionnaire or validated anxiety measure, as finalized in the study assessment plan.
Satisfaction With Consent Process
Participant-reported satisfaction with the assigned consent process, including perceived clarity and helpfulness of the information provided.
Decisional Confidence or Self-Efficacy
Participant-reported confidence in the decision to proceed with the procedure and perceived ability to make an informed decision after the consent process.
Usability and Acceptability of Consent Process
Participant-reported usability and acceptability of the assigned consent process. For participants in the digital-supported arm, this will include perceived usability and acceptability of the video and AI-based question-answering tool.
Other outcomes
Retention of Key Knowledge
Participant retention of key consent-related knowledge at short follow-up after the procedure.
Subgroup Differences in Comprehension and Consent Outcomes
Exploratory subgroup analyses by age, education, prior endoscopy experience, digital literacy, procedure type, and site.
Comparative Performance Across Study Settings
Exploratory comparison of intervention performance across North American and European participating sites.
