Summary
Standardized patients (SPs) accurately assess clinical competence. SP accuracy is good to very good, influenced by checklist design but consistent over time.
Area of Science:
- Medical Education
- Performance-Based Assessment
- Clinical Skills Evaluation
Background:
- Large-scale performance-based assessments utilize simulated patients (SPs) to evaluate medical professionals' clinical competence.
- SPs simulate clinical scenarios and record examinee performance using checklists.
Purpose of the Study:
- To evaluate the accuracy of SPs in recording checklist items during clinical competence assessments.
- To determine if checklist characteristics (length, type, clarity) affect SP accuracy.
- To assess the impact of examination timing (time of day, day within examination) on SP accuracy.
Main Methods:
- Analysis of checklist recordings made by SPs during large-scale performance-based assessments.
- Statistical evaluation of SP accuracy in relation to checklist features and examination timing.
Main Results:
- SPs demonstrated good to very good accuracy in recording checklist items.
- Checklist length, item type, and item clarity significantly influenced SP accuracy.
- SP accuracy remained consistent throughout a single day and across a 15-day examination period.
Conclusions:
- SPs are reliable tools for assessing clinical competence with good to very good accuracy.
- Checklist design is a critical factor in optimizing SP performance.
- SP accuracy is stable, unaffected by the duration or timing of the examination.
