Objective Structured Clinical Examination technical skill stations correlate more closely with postgraduate year...

Area of Science:

• Medical Education
• Surgical Training Assessment

Background:

• The validity of Objective Structured Clinical Examinations (OSCE) relies on their ability to differentiate trainee competency levels.
• The optimal OSCE station composition for maximizing assessment validity remains undetermined.
• Evaluating clinical skills of medical students and residents is a key application of OSCE.

Purpose of the Study:

• To investigate the relative correlation between different OSCE station types and the postgraduate year (PGY) level of surgical residents.
• To determine which OSCE station types are more effective in distinguishing between varying levels of resident training.

Main Methods:

• A 12-station OSCE was administered to surgical residents across all PGY levels at a university program.
• Individual station scores and the total examination score were correlated with PGY level.
• Statistical analysis was performed to compare the correlation coefficients of different station types.

Main Results:

• The overall correlation between total OSCE score and PGY level was strong (R = 0.681).
• Technical skill stations showed a significantly higher correlation with PGY level (0.679) compared to clinical skill stations (0.203).
• The difference in correlation between technical and clinical skill stations was statistically significant (P < 0.05).

Conclusions:

• Technical skill evaluation in OSCEs is more sensitive for distinguishing the training levels of surgical residents.
• OSCE station design should prioritize technical skill assessment to enhance validity in surgical education.
• These findings can inform the development of more effective OSCE formats for surgical residency programs.
