Video education can improve awareness of risks for patients undergoing endoscopic retrograde cholangiopancreatography: A randomized trial. Issue 12 (21st November 2019) - Xia, Tian
Abstract : Objective: We conducted a randomized trial aiming at improving patients' informed consent for undergoing endoscopic retrograde cholangiopancreatography (ERCP) in clinical care by comparing the efficacy of an additional educational video to written informed consent with that of written informed consent alone. Methods: This was a single‐center, randomized controlled trial. Consecutive patients undergoing ERCP were randomized to a video education or a control group. An educational video detailing ERCP procedure plus standard written informed consent was administered to the video education group, while the control group reviewed standard written informed consent only. The primary outcome was the patients' perception of the risk or possibility of ERCP complications. Their perception of the benefits of ERCP, alternative treatments and overall satisfaction with the process of informed consent were also compared. Results: In total 205 patients were included in the study (104 in the control group and 101 in the video education group). Patients' comprehension of ERCP‐related complications in the video education group was significantly increased ( P < 0.001), and these patients were more likely to correctly identify the incidence of such complications. Significantly more patients in the video education group were very satisfied with informed consent process (87.1% vs 76.0%, P = 0.040) and fewer patients needed additional explanations (31.7% vs 47.1%, P = 0.024). Conclusions: A supplementary educational video could greatly improve patient's understanding of ERCP procedure, in particular, its potential risks and complications, as well as their overall satisfaction with the process of informed consent (ClinicalTrials.gov no. NCT02810379).
