Design outcomes

Primary

Measure	Time frame
The same questionnaire was used for both groups. The comprehension of informed consent, satisfaction, clarity of explanation, and attitude of the doctor will be evaluated on a 5-point Likert scale. The patients were also asked questions to evaluate their level of understanding and to score their understanding.	—

Secondary

Measure	Time frame
Patient background will be analyzed in terms of age, gender, educational background, time elapsed since tumor discovery, presence of a patient present when viewing the video, type of disease, surgical procedure, presence of symptoms, and ASA-PS. A questionnaire will be administered to physicians and nurses who provide explanations to patients to determine whether there was an improvement in patient understanding and satisfaction or a reduction in the burden on the medical staff when using the surgical explanation videos.	—
