Background: Hypertension challenges arise in part from poor adherence due to inadequate patient education. VR offers immersive learning to improve hypertension knowledge.
Objective: To compare VR education with traditional verbal education to improve hypertension knowledge.
Methods: In this randomised trial, 182 patients with hypertension were assigned to receive either traditional physician-led education (n = 88) or VR education (n = 94) with equivalent content. The VR group experienced a 3D video using Oculus Quest 2 headsets. Knowledge was assessed post-intervention using a 29-item questionnaire. The primary outcome was the objective score. Subjective satisfaction and responder characteristics were secondary outcomes.
Results: Median objective scores were significantly higher for VR (14, IQR 3) versus traditional education (10, IQR 5), p < 0.001, indicating superior hypertension knowledge acquisition with VR. Subjective satisfaction was high in both groups. Participants were categorized into low (first quartile) and medium-high (second to fourth quartiles) responders based on their scores. Low responders had a significantly higher prevalence of older women than medium-high responders (57% vs. 40% female, p = 0.024; 68 vs. 65 years), p = 0.036).
Conclusions: VR outperforms traditional education. Tailoring to groups such as older women can optimise learning.
