Background: Appropriate information about the benefits and risks of invasive procedures is crucial, but limited data is available in this field. The aim of this study was to evaluate the incremental value of a short video about coronary angiography compared with standard information, in terms of patient understanding, satisfaction and anxiety. Methods: This prospective multicenter study included patients admitted for scheduled coronary angiography, who were randomized to receive either standard information or video information by watching a three-dimensional educational video. After information was delivered, patients were asked to complete a dedicated 16-point information questionnaire, as well as satisfaction and anxiety scales. Results: From 21 September to 4 October 2015, 821 consecutive patients were randomized to receive either standard information (n = 415) or standard information with an added educational video (n = 406). The information score was higher in the video information group than in the standard group (11.8 +/- 2.8 vs 9.5 +/- 3.1; P \textless .001). This result was consistent across age and education level subgroups. Self-reported satisfaction was also higher in the video information group (8.4 +/- 1.9 vs. 7.7 +/- 2.3; P \textless .001), while anxiety level did not differ between groups. The variables associated with a higher information score were the use of the educational video, younger age, higher level of education, previous follow-up by a cardiologist, prior information about coronary angiography and previous coronary angiography. Conclusions: In comparison with standard information, viewing a dedicated educational video improved patients' understanding and satisfaction before scheduled coronary angiography. These results are in favor of widespread use of this incremental information tool. (C) 2018 Elsevier Inc. All rights reserved.
