A randomised control trial to evaluate a novel 3D animation for patient education on Menière's disease

Background: Menière’s disease (MD) is a disorder of the inner ear impacting hearing and balance. Traditionally, text-based and two-dimensional diagrammatic resources are used for patient education. In this study, we investigated if a novel 3D animation would improve patient understanding of MD.

Methods: A randomized single-blinded study conducted at Sydney Adventist Hospital (Tertiary Teaching Hospital) involving 40 participants without a formal prior diagnosis and no prior knowledge of MD. Participants were randomized into two groups, with control group (n = 20) educated traditionally utilising two-dimensional images and a verbal explanation of MD and intervention group educated traditionally with the addition of the 3D animation (n =20). Main outcomes measured were self-reported perceived understanding of inner ear anatomy, symptomatology, pathophysiology and treatment of MD. Objectively, this understanding was quantified through the use of a quiz. Additionally, ten otolaryngologists were interviewed to evaluate the utility of the 3D animation and provide feedback regarding utility and improvement.

Results: There was a significant higher mean difference across aforementioned domains with 3D animation group. In addition, 100% of otolaryngologists reported the animation to be useful in explaining anatomy and disease process with MD patients.

Conclusions: The use of 3D animation significantly improves participants understanding of complex disease processes such as MD. It is engaging for patients and useful for clinicians.
