Abstract
Background
There is limited time within the clinical workflow of most pediatric surgeons to obtain a comprehensive, well informed consent. This study evaluates whether ad-lib access to an online video on the consent dialogue enhances the consent process for inguinal hernia repair (IHR) in children.
Methods
The study was approved by the state ethics board. A 6-min video of a consent speech on IHR was produced and uploaded to a nonpublic online channel, explaining the condition, procedure, complications, and postoperative expectations. A total of 50 families were randomized to conventional, face-to-face consenting in clinic either with (intervention) or without (control) access to the online video. During their child’s IHR, the parents were asked to complete the State–Trait-Anxiety-Inventory (STAI), a modified Friedlander questionnaire on assessing knowledge sufficient to provide informed consent, and a validated satisfaction survey. Scores of the intervention and control group were statistically compared.
Results
The intervention group demonstrated significantly decreased anxiety measured with the STAI (p = 0,026) and increased knowledge (p = 0,016) compared to controls. There was no difference in satisfaction (p = 0,557).
Conclusion
Preoperatively providing access to an online consent video regarding IHR reduces anxiety and enhances knowledge without altering satisfaction level. Adjunct online videos are a useful tool to enhance the consent process.
