Abstract
PURPOSE: To assess whether a multimedia-assisted preoperative informed consent procedure has an effect on patients' knowledge concerning cataract surgery, satisfaction with the informed consent process, and reduction in anxiety levels. SETTING: Hietzing Hospital, Vienna, Austria. DESIGN: Prospective randomized controlled clinical trial. METHODS:Patients participated in an informed consent procedure for age-related cataract surgery that included thestandard approach only (reading the information brochure and having a standardized face-to-face discussion) or supplemented with a computer-animated video. The main outcome was information retention assessed by a questionnaire. Further outcome measures used were the State-Trait Anxiety Inventory, the Visual Function-14 score, and an assessment of satisfaction. RESULTS: The study included 123 patients (64 in standard-only group; 59 in computer-animated video group). Both groups scored well on the questionnaire; however, patients who watched the video performed better (82% retention versus 72%) (P = .002). Scores tended to decrease with increasing age (r = -0.25, P = .005); however, this decrease was smaller in the group that watched the video. Both groups had elevated anxiety levels (means in video group: anxiety concerning the current situation [S-anxiety] = 63.8 ± 9.6 [SD], general tendency toward anxiety [T-anxiety] = 65.5 ± 7.9; means in control group: S-anxiety = 61.9 ± 10.3, T-anxiety = 66.2 ± 7.8). CONCLUSIONS: A high level of information retention was achieved using an informed consent procedure consisting of an information brochure and a standardized face-to-face discussion. A further increase in information retention was achieved, even with increasing patient age, by adding a multimedia presentation.
