Brief summary
The primary purpose of the study is to compare video assisted consent to standard verbal consent. We hypothesise that video assisted consent would help improve patient understanding and recall of the risks involved with their planned procedures, compared to standard verbal consent.
Interventions
Patients who came forward for either elective gastroscopy or colonoscopy were randomised to receive either standard verbal consent, or video assisted consent (intervention).
Two videos were created, professionally filmed and narrated by a nurse investigator. The videos were 3.5 minutes long and designed to cover all aspects of legal informed consent. Subtitles were included to highlight individual risks as they were mentioned.

Patients who came forward for either elective gastroscopy or colonoscopy were randomised to receive either standard verbal consent, or video assisted consent (intervention). Two videos were created, professionally filmed and narrated by a nurse investigator. The videos were 3.5 minutes long and designed to cover all aspects of legal informed consent. Subtitles were included to highlight individual risks as they were mentioned. The intervention was the demonstration of the video, played in the patient bed space and displayed on an A5-sized tablet with the use of earphones in order to minimise contamination bias with neighbouring patients. Patients who were scheduled for gastroscopy were shown the gastroscopy-specific video. Likewise for patients scheduled for colonoscopy. Patients who were scheduled to have both procedures were shown both videos. Following the video, patients had the opportunity for further discussion and to ask questions. Patients where then asked to sign a standard hospital consent form, and fill out the questionnaire.

Inclusion criteria
All consecutive patients aged 18 years or older scheduled for an outpatient gastroscopy, colonoscopy or both were considered for enrolment in the trial.
Exclusion criteria
Patients were excluded if they were having a procedure other than colonoscopy or gastroscopy such as Endoscopic Retrograde Cholangiopancreatography (ERCP) or a planned therapeutic intervention such as dilatation or variceal banding. Further exclusions included patients who would ordinarily require a third party to sign consent (due to age, intellectual disability, lack of capacity, those visually or hearing impaired) and patients with a language barrier such that an interpreter was required.
