Modeling surgical expertise for motor skill acquisition

Area of Science:

• Medical Education
• Surgical Skills Training
• Minimally Invasive Surgery

Background:

• Developing efficient surgical hand skills is crucial for procedures like inguinal hernia repair.
• Traditional training methods may not fully optimize the acquisition of complex surgical techniques.
• Innovative teaching strategies are needed to enhance surgical proficiency.

Purpose of the Study:

• To evaluate the impact of expert cognitive modeling, auditory elaboration, and split-screen video analysis on surgical residents' performance.
• To assess the effect of these techniques on hand movements during inguinal hernia repair using the McVay technique.
• To determine the efficacy of a novel teaching approach for surgical skill acquisition.

Main Methods:

• A pretest-posttest control group design was employed with six surgical residents.
• Residents performed an inguinal hernia repair using the McVay technique on cadavers.
• The experimental group received expert cognitive modeling, auditory elaboration, and split-screen analysis post-pretest.

Main Results:

• The experimental group demonstrated significant improvements in surgical instrument control and manipulation.
• Shorter operation times were observed in the group that received the enhanced training.
• More purposeful and precise surgical movements were exhibited by the experimental group.

Conclusions:

• The combined teaching intervention, including cognitive modeling and auditory elaboration, effectively enhanced learning of the McVay technique.
• Mindfulness learning principles appear to be beneficial for mastering surgical procedures.
• This approach shows promise for improving surgical education and patient outcomes.
