Summary
A validated shave biopsy checklist improves procedural competency assessment in medical education. This tool demonstrates high reliability and accuracy, supporting its use for objective mastery standards.
Area of Science:
- Medical Education
- Surgical Skills Assessment
- Dermatology Procedures
Background:
- Current residency training lacks reliable methods for assessing procedural competency.
- Existing assessment tools for procedures show poor reliability and have not been validated.
Purpose of the Study:
- To validate a shave biopsy checklist for assessing procedural competency in medical education.
- To evaluate the content validity, interrater reliability, and accuracy of the shave biopsy checklist.
Main Methods:
- A mixed-methods study involving family medicine and dermatology faculty at two academic centers.
- Validation involved scoring simulated procedures using the checklist, with assessments of content validity, interrater reliability, and accuracy.
- Iterative refinement of the checklist based on initial focus group feedback and subsequent testing.
Main Results:
- Initial focus groups indicated 16 of 18 items met interrater reliability thresholds, with overall checklist reliability at 74%.
- Content validity index improved from insufficient to 0.76 after item refinement, surpassing the required threshold.
- Final testing demonstrated high interrater reliability (91%) and accuracy (84.9%), with 14 of 16 items exceeding 90% reliability.
Conclusions:
- The validated shave biopsy checklist exhibits strong content validity, interrater reliability, and accuracy.
- This checklist serves as an objective standard for mastery in medical education.
- The tool is suitable for formative assessment of procedural competency in shave biopsies.
