Concurrent validity of objective assessment by finger tracking for open surgical suturing training - 26/09/24

Background |
The aim of this study is to evaluate whether the parameters ‘time’ and ‘distance’, measured by SurgTrac, correlate with the assessment of the same skills by blinded experts.
Methods |
Basic open suturing tasks were executed by medical students. SurgTrac software measured objective parameters by tracking fingers. The executed tasks were recorded by a tablet and additionally assessed by a blinded expert with a Competency Assessment Tool-form (CAT-form). A Pearson's correlation was used to investigate the correlation between the parameters and the outcomes of the expert assessment.
Results |
A strong correlation between the measured parameters of SurgTrac and the expert-assessment was found for knot tying by hand (r = −0.703) and vertical mattress suture (r = −0.644) and a moderate correlation for transcutaneous suture (r = −0.555) and intracutaneous suture (r = −0.451).
Conclusion |
The use of finger tracking by SurgTrac showed a good concurrent validity for the basic open suturing tasks knot tying by hand, transcutaneous suture and vertical mattress suture.

• | Currently, there are limited methods for training basic open suturing skills. |
• | Tracking of fingers is a feasible method to assess basic open suturing tasks. |
• | During tracking objective parameters can be measured, such as time and distance. |
• | Objective assessment correlates moderately to strongly with expert assessment. |
• | Concurrent validity was found for three basic open suturing tasks. |
