A Randomized Controlled Trial Evaluating the Effect of an Educational Video on Patient Understanding of Midurethral Sling

Abstract

ObjectiveThe primary objective was to evaluate the use of a novel video for enhancing patient knowledge of midurethral sling compared with standard handout.MethodsParticipants scheduled for midurethral sling were randomized to 1 of 2 preoperative educational interventions, either video or standard handout. The primary outcome was change in knowledge measured via a 15-question questionnaire completed immediately before and after the intervention. Secondary outcomes were knowledge retention, urinary symptoms, decision satisfaction, and regret measured via validated questionnaires at 2 and 6 weeks postoperatively. Data are presented as median (interquartile range) and comparisons between intervention groups made using non-parametric statistics. A sample size of 16 per arm was calculated to detect a 20% effect size.ResultsThirty-eight participants, 19 per site, were randomized from August 2019 to October 2020 and 37 (97%) completed the primary outcome per protocol. Median age was 51 years (18 years), and there were no significant demographic differences between groups. Participants randomized to video demonstrated greater change in knowledge than those randomized to handout (+8.5 (3) vs +2.0 (4), P < 0.0001). Those randomized to video demonstrated improved 6 week postoperative urinary symptoms (Urogenital Distress Inventory-6, 0.0 [8.3] vs 14.6 [26.0]; P = 0.02; Incontinence Severity Index, 0.0 [2] vs 3.0 [4]; P = 0.005). There were no differences in satisfaction with decision (5.0 [0] video vs 5.0 [0.9] handout; P = 0.48) or decision regret (1.0 [0.5] video vs 1.0 [0.8] handout; P = 0.80) at 6 weeks postoperatively.ConclusionsA preoperative educational video improved knowledge and urinary symptoms after midurethral sling compared with a standard handout.
