Kurze Zusammenfassung

The use of electronic media in informed consent giving has become increasingly important in recent years. Due to the easy access to information via electronical media, patients are primed in a heterogeneous manner concerning expectations and wishes regarding surgical interventions. Inherent to its nature elective interventions are critically questioned as there is time for information gathering and reflection.

In this study, the investigators set out to investigate the effect of an educational video as a supporting element in the process of informed consent giving for one the most frequently performed interventions in general surgery, namely inguinal hernia repair.

In a multi-center setup, eligible patients for primary inguinal hernia repair will be randomly assigned to 1 of 3 groups. The intervention video provides basic principles of endoscopic extraperitoneal hernia repair. The second video is similar in length and design and displays general aspects of day surgery in the two study centres. The third group's link will lead to the digital version of the informed consent. Primary outcomes will consist of 1) score in a multiple choice test assessing gain of knowledge regarding hernia repair, 2) difference in the State-Trait Anxiety Inventory (STAI) and 3) patient satisfaction questionnaire (ICF, Picker Institute, Germany) as assessed 1-2 days after the first consultation.

Etikette: Hernia video

Art: Active Comparator

Beschreibung: The video of the intervention group will provide a short (< 5 min) summary explaining the basic principles of endoscopic extraperitoneal hernia repair, its possible complications and the postoperative course. After carefully watching the video, participants should be able to correctly answer to a multiple-choice test consisting of 12 questions related to the aforementioned topics.

Etikette: Mock video

Art: Placebo Comparator

Beschreibung: This video is a general documentation of the "typical" day of surgery in the day clinic. The information is essentially limited to the pictorial representation of the individual wards which the patient will pass through during the operation (arrival at the clinic, admission, transport to the operating theatre, recovery room, discharge). The video explicitly does not transport any information that could be helpful for answering the quiz questions or for medical understanding of the operation itself.

Etikette: Control group

Art: Sham Comparator

Beschreibung: The link of the third group leads to a digital version of the information sheet, which has already been discussed with all patients during the informed consent discussion. The digital version of the informed consent form allows the patient to read the information again. The third group thus corresponds to the standard of care.
