Virtual-reality-enhanced mannequin to train emergency physicians to examine dizzy patients using the HINTS method

Area of Science:

• Emergency Medicine
• Medical Simulation
• Neurology

Background:

• Acute vertigo is a common emergency department complaint requiring skilled assessment.
• The HINTS protocol aids in differentiating stroke from other vertigo causes but requires adequate training.
• Lack of training hinders the routine application of the HINTS protocol in emergency settings.

Purpose of the Study:

• To evaluate the effectiveness of a mannequin-based virtual reality simulator (MBVRS) for training emergency physicians in the HINTS protocol.
• To assess the impact of simulation-based training on diagnostic performance for acute vertigo.

Main Methods:

• A monocenter, prospective, randomized cohort study involving 34 emergency physicians.
• Participants were divided into a control group (theoretical lesson) and a test group (theoretical lesson plus MBVRS training).
• Diagnostic performance was evaluated using the simulator at 1 and 6 months post-training.

Main Results:

• The test group demonstrated significantly higher diagnostic performance for the HINTS method compared to the control group at 1 month (89% sensitivity vs. 45%, 100% specificity vs. 86%).
• This performance advantage was sustained at the 6-month follow-up.
• p < .001, Fisher's exact test.

Conclusions:

• MBVRS is an effective educational tool for mastering the HINTS protocol in emergency medicine.
• Simulation-based training provides a lasting improvement in diagnostic skills for acute vertigo management.
• MBVRS training enhances emergency physician competency in applying the HINTS protocol effectively.
