The ideal interval for laparoscopic suturing simulator training is not linked to performance improvement. However, shorter training intervals may enhance skill acquisition in surgical trainees.

Area of Science:

Medical Education
Surgical Simulation
Skills Acquisition

Background:

Proficiency-based training is crucial for surgical skills.
Optimizing training schedules enhances learning efficiency.

Purpose of the Study:

To determine the optimal interval between training sessions for laparoscopic suturing.
To analyze the relationship between training intervals and performance in a simulator curriculum.

Main Methods:

Analysis of data from 3 randomized controlled trials (n=66) in laparoscopic suturing.
Correlation of performance changes with intertraining intervals in a Fundamentals of Laparoscopic Surgery curriculum.

Main Results:

Participant performance significantly improved post-training (530 +/- 58s to 81 +/- 14s).

No correlation found between intertraining interval and performance change (r = .05, P = .30).

Shorter intervals correlated with shorter training duration (r = .35, P = .005).

Conclusions:

Intertraining interval does not impact performance change in simulator training.
Shorter intervals may be associated with improved skill acquisition.
Further research is needed to validate these findings.
