Video-Assisted Versus Conventional Surgical Informed Consent in Visceral Surgery-A Cluster Quasi-Randomized Clinical Trial.
Trial report in World journal of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundComprehensive informed consent is a core surgical responsibility but is increasingly challenged by rising patient volumes and limited personnel resources. Digital solutions in healthcare offer opportunities to optimize patient education. Video-assisted informed consent may reduce time expenditure without compromising informational quality. The objective was to compare video-assisted with conventional informed consent regarding duration, patient understanding, patient, and physician satisfaction.
methodsIn this prospective, cluster quasi-randomized clinical trial at the University Hospital Wuerzburg, Germany (September 2023-March 2025), 153 of 330 screened patients scheduled for elective cholecystectomy or colon resection were enrolled. The intervention group received a video developed by medudoc education GmbH, while the control group received physician-led informed consent according to the hospital's standard. Consultation duration was recorded using a stopwatch. Patients completed questionnaires on satisfaction and understanding immediately after consent and postoperatively, physicians rated satisfaction at study completion. The primary outcome was time reduction for the physician consultation time. Secondary outcomes included patient understanding, patient satisfaction, physician satisfaction, and postoperative pain.
resultsOf 153 participants, 84 (55%) received video-assisted and 69 (45%) conventional consent. Median physician consultation time was significantly reduced with video assistance for cholecystectomy (1.5 vs. 8.1 min) and colon resection (3.3 vs. 11.9 min). Patient understanding, satisfaction, and postoperative pain outcomes were high in both groups. Physician satisfaction with the video-assisted process was consistently high.
conclusionsVideo-assisted surgical informed consent serves as a valuable adjunct in preoperative patient education and represents a promising approach to digital innovation in clinical practice.
