Does Objective Structured Clinical Examinations Score Reflect the Clinical Reasoning Ability of Medical Students?

Area of Science:

• Medical Education
• Clinical Reasoning Assessment

Background:

• Clinical reasoning is crucial for physician competence and medical school training.
• Objective Structured Clinical Examinations (OSCE) are standard for assessing medical student competency.
• The ability of OSCE to evaluate clinical reasoning remains unclear.

Purpose of the Study:

• To investigate if OSCE scores correlate with medical students' clinical reasoning abilities.
• To determine the effectiveness of OSCE in assessing clinical reasoning.

Main Methods:

• Sixty-five fourth-year medical students participated.
• Students completed a 4-case OSCE using standardized patients.
• Clinical reasoning was assessed by differential diagnoses and compatible/incompatible findings; scores were correlated with OSCE, diagnostic accuracy, and GPA.

Main Results:

• Clinical reasoning scores correlated with diagnostic accuracy and GPA (p=0.038, p=0.002).
• No significant correlation was found between clinical reasoning scores and OSCE scores (p=0.276).
• Total OSCE scores did not correlate significantly with clinical knowledge, reasoning, diagnostic accuracy, or GPA.

Conclusions:

• OSCE scores from patient encounters did not reflect students' clinical reasoning abilities.
• Current OSCE methods may be insufficient for evaluating clinical reasoning.
• Strengthening OSCE to assess clinical reasoning is recommended.
