- Abstract
Purpose: To assess the effects of the American Academy of Ophthalmology's 2015 patient education video on patient information retention and anxiety preoperatively, on the day of surgery and postoperatively. Methods: This is a prospective, surgeon-blinded randomized controlled trial at the University of Chicago Medical Center. Ninety-one patients with a diagnosis of first-eye cataract were randomized into either a video or control group. Subjects in both groups received face-to-face discussion with the surgeon and an informational brochure at the preoperative evaluation. Participants in the video group then viewed a four-minute educational video at the preoperative evaluation and on the day of surgery. Both groups completed an information retention quiz and a state anxiety assessment at the preoperative visit, on the day of surgery, and on the postoperative week one visit. Subject understanding of cataract surgery was measured using a twelve-question multiple choice quiz. State anxiety was measured by State Trait Anxiety Inventory-Y1 survey score. Results: Participants in the video group did not score significantly higher on the information retention quiz compared with the control group at the preoperative evaluation (8.7 ± 2.4 vs 7.7 ± 2.5, P = 0.07), but did so on the day of surgery (11.2 ± 0.8 vs 8.4 ± 1.7, P < 0.001) and postoperative week 1 visit (10.8 ± 1.5 vs 9.0 ± 2.0, P < 0.001). Subjects in the video group were significantly less anxious on the day of surgery (26.4 ± 5.1 vs 41.1 ± 10.3, P < 0.001). Conclusions: Video supplementation to the traditional informed consent process demonstrated an improvement in patient understanding of cataract surgery at multiple timepoints and decreased anxiety on the day of surgery.
