Effectiveness of a CD-ROM multimedia tutorial in transferring cognitive knowledge essential for laparoscopic skill...

Area of Science:

• Surgical Education
• Medical Informatics
• Distance Learning

Background:

• Computer-assisted instruction (CAI) offers potential benefits for surgical education, including enhanced efficiency, effectiveness, standardization, and accessibility.
• This study evaluates knowledge acquisition in laparoscopic skills using a standardized tutorial delivered through CD-ROM compared to a live instructor.

Purpose of the Study:

• To compare the effectiveness of a standardized laparoscopic surgical skill tutorial delivered via CD-ROM versus a live instructor.
• To assess knowledge gains in different surgical groups using computer-assisted instruction.

Main Methods:

• A standardized tutorial was developed and converted into a multimedia CD-ROM format.
• Experienced US surgeons (n=52) received live instruction, while experienced US surgeons (n=27), US surgical residents (n=59), and Greek surgeons (n=63) used the CD-ROM tutorial.
• A 51-item knowledge test was administered pre- and post-tutorial.

Main Results:

• A significant increase in knowledge scores (P <0.01) was observed across all groups after tutorial instruction.
• The magnitude of knowledge gain was similar across all groups, with no significant differences among US-trained groups post-instruction.

Conclusions:

• The CD-ROM tutorial effectively facilitates the transfer of cognitive information essential for laparoscopic skill development.
• Distance learning modalities utilizing this tutorial program appear to be a feasible option for surgical education.
