Video-enhanced informed consent improves patient comprehension in reverse total shoulder arthroplasty: a randomized controlled trial

Background Informed consent for reverse total shoulder arthroplasty (rTSA) requires thorough patient understanding, yet only 29% of patients adequately comprehend preoperative information. This study evaluated whether preoperative educational videos enhance patient comprehension compared to standard verbal explanations alone and assessed impact on consultation time and demographic variations. Methods This prospective randomized controlled trial included 60 patients undergoing rTSA, assigned 1:1 to video education or control groups. The video group viewed a 2-minute explanatory video before informed consent discussion; the control group received only verbal discussion. Afterwards, all participants completed a 7-question test on procedural knowledge, benefits, and risks. Results The video education group achieved significantly higher scores (5.70/7) compared to controls (4.67/7) (p=0.002). Significant improvements were observed across all subgroups, Vulnerable subgroups including older (p=0.02), lower-educated (p=0.007) participants and non-native speakers (p=0.04) also demonstrated benefit. Conclusion An explanatory video before informed consent discussion significantly improved procedural comprehension compared to standard discussion alone. Vulnerable subgroups, older participants, non-native speakers, and those with lower educational attainment showed particular benefit. These findings support integrating video education into standard preoperative rTSA protocols.
