Evaluating an AI-Based Augmented Reality System for Hand Hygiene Training in Healthcare and University Settings

What this Trial Is About

Researchers are evaluating an edge artificial intelligence AI-based augmented reality AR training and assessment system designed to improve hand hygiene knowledge and practice in healthcare and educational settings. This multi-centre, mixed-methods cluster randomised controlled trial involves around 480 participants, including undergraduate students in health-related fields and healthcare professionals or supporting staff from hospitals. The study aims to compare this new AI-based AR system with an existing educational program that uses hand scanner feedback and instructional videos to see if the new method is not less effective. Participants will be randomly assigned to one of two groups. One group receives the AI-based AR training, which offers real-time, personalized feedback on handwashing performance using computer vision. The other group receives feedback from a fluorescent hand scanner and watches a standard seven-step handwashing video. Both groups perform a baseline handwash with fluorescent powder, followed by training, then a second handwash. The study includes a qualitative component where a subset of participants shares their experiences and perceptions of the training through interviews. Participants will provide consent and complete questionnaires assessing their hand hygiene knowledge and practice before and after training. Handwashing is assessed objectively by measuring fluorescent residue using a scanner and by expert evaluation of recorded videos. Researchers will measure improvement in the amount of fluorescent residue left on hands as the primary outcome, along with knowledge scores, proper handwashing steps, and user satisfaction. Data will be anonymized and securely stored, with a low risk of allergic reactions from the fluorescent powder. Participation lasts through the pre- and post-training assessments within one study visit.
