Aging significantly impacts surgical skills, with younger surgeons outperforming older ones in simulator tasks. Visuo-haptic simulation can help assess and maintain surgical abilities in older professionals.

Area of Science:

  • Surgical Education
  • Gerontology
  • Human Factors Engineering

Background:

  • Aging can diminish manual dexterity crucial for surgery.
  • Objective assessment of age-related surgical skill decline is lacking.
  • Surgical simulation offers a standardized training and evaluation method.

Purpose of the Study:

  • To evaluate the effect of age on basic surgical task performance.
  • To assess the utility of visuo-haptic simulation in studying age-related surgical skill changes.

Main Methods:

  • 39 participants (20 young, 19 older adults) performed three surgical tasks on a visuo-haptic simulator.
  • Tasks included: incision, needle threading, and suturing.
  • Performance metrics (errors, trajectory, time) were analyzed between age groups and across practice repetitions.

Main Results:

  • Younger participants demonstrated superior performance across all tasks compared to older adults.
  • Older surgeons showed less improvement with practice than younger surgeons.
  • Specific deficits observed in older adults included reduced tissue cutting, increased dexterity errors, and slower suturing.

Conclusions:

  • Age significantly impairs performance in fundamental surgical skills.
  • Visuo-haptic simulation effectively evaluates age-related surgical skill differences.
  • Periodic simulation-based training may help older surgeons maintain proficiency and counteract skill degradation.
