Video-assisted informed consent shortens the physician's consent discussion by 72 to 81%
University Hospital Würzburg compared video-assisted and conventional surgical informed consent. With video, the median physician discussion time before cholecystectomy fell from 8.1 to 1.5 minutes (−81%) and before colon resection from 11.9 to 3.3 minutes (−72%). Patient comprehension and satisfaction were high in both groups.

Studiendesign
Two procedures, two methods, one stopwatch
Video-assisted informed consent was compared with conventional physician-led informed consent according to the hospital's standard. Allocation was by study period – all patients in a period received the same method, and the periods alternated.
- 1Individual video
- 2Video at your own pace
- 3Supplementary discussion

Was die Studie gemessen hat
72 to 81% less physician discussion time
The time saving was the study's primary endpoint. It measured the time the physician spends on informed consent – in the video group, the supplementary discussion after the video. Before cholecystectomy, it fell by 6.6 minutes (−81%), before colon resection by 8.6 minutes (−72%; p < 0.0001 in each case).
A clear time advantage remains even with video creation
Most physicians needed one to three minutes to compile an individual video. Adding two minutes for this, physician time with video is still 57% (cholecystectomy) and 55% (colon resection) shorter.
Comprehension and satisfaction high – in both groups
Patients rated their comprehension and satisfaction before and after the operation very highly in both groups; the differences between the groups were not statistically significant. Pain scores after the operation were also low in both groups.

Physicians rate the method positively
After the study ended, 14 participating physicians who had performed both methods rated video-assisted informed consent.
