Step 23 Implementation for Assessment Credentialing

The use of virtual reality simulators for screening resident applicants, resident assessment, and physician credentialing should likely be reserved until after predictive validity and learning curves have been reliably established, since then and only then accurate projections as to a subject's performance can be made.

The stakes are otherwise too high in these situations to rely on less rigorous methods of validity and a lack of the establishment of a learning curve. The use of simulators for assessment and credentialing is destined to play an important role in medical education; however, it may take the better part of a decade before this becomes a reality.

Medical students had a 67% correct diagnosis rate of malignant versus nonmalignant cases compared with 56% for urology residents. Residents felt the content (force feedback) lacked realism and concurrent validity was not demonstrated, as residents were able to correctly identify malignancy on the Merck trainer (gold standard) 96% of the time.

Percutaneous access is a skill set that requires excellent visual-spatial awareness and experience.
