Improved cardiac auscultation competency interweaving visual, auditory, and tactile stimuli: a preliminary study

Area of Science:

• Medical Education
• Cardiology
• Simulation-Based Learning

Background:

• Cardiac auscultation is a fundamental clinical skill.
• Deterioration in cardiac auscultation skills is a global concern.
• Traditional teaching methods may not be sufficient for optimal skill acquisition.

Purpose of the Study:

• To evaluate the effectiveness of multisensory stimuli in teaching cardiac auscultation.
• To compare multisensory learning with traditional methods in first-year medical students.
• To assess the impact on diagnostic accuracy and knowledge acquisition.

Main Methods:

• Pilot randomized controlled trial with 32 first-year medical students.
• Intervention group used multisensory stimuli; control group used traditional methods.
• Post-assessment measured diagnostic accuracy and knowledge acquisition of cardiac sounds.

Main Results:

• Multisensory group showed significantly higher diagnostic accuracy (100% vs. 60%).
• Knowledge acquisition was substantially better in the multisensory group (80% vs. 50%).
• Statistical significance achieved for both outcomes (p<0.042 and p<0.031).

Conclusions:

• Multisensory stimuli significantly enhance cardiac auscultation competency.
• This method is a cost-effective, viable alternative to expensive simulators.
• Holds promise for global application in improving patient care.
