Using interactive videodisc to test advanced airway management skills.

Area of Science:

• Medical Education
• Simulation-based Learning
• Emergency Medicine Training

Background:

• Advanced airway management is a critical skill in emergency medicine.
• Traditional teaching methods may not fully address the psychomotor demands of these procedures.
• Interactive videodisc (IVD) technology offers a novel approach to skills acquisition.

Purpose of the Study:

• To compare the effectiveness of the Actronics Interactive Learning System (IVD) versus traditional lecture/demonstration for teaching advanced airway management psychomotor skills.
• To evaluate the impact on endotracheal (ET) intubation and esophageal obturator airway (EOA) insertion proficiency.

Main Methods:

• A nonrandomized, nonequivalent comparison group design was employed.
• 86 American Heart Association (AHA) advanced cardiac life support (ACLS) students were divided into IVD (n=41) and traditional (n=45) groups.
• Performance was assessed by the number of attempts for successful ET intubation and EOA insertion.

Main Results:

• No significant difference in ET intubation success rates between IVD and traditional methods.
• IVD method showed a significant positive treatment effect for initial EOA insertion certification (p=0.004).
• This effect was not observed for recertification or ET intubation, and students desired instructor availability.

Conclusions:

• Interactive videodisc technology plays a valuable role in teaching complex advanced airway management skills.
• IVD may be particularly beneficial for initial learning of specific airway devices like the EOA.
• Further research could explore optimal integration of IVD with human instruction.
