Technique was found to be only 20% reliable.  Can be safely stated that this procedure, which is standard at so many hospitals, is without value.

A recent study of misidentification in the neonatal intensive care unit (NICU) over a 1-year period found "not a single day was free of risk for patient misidentification"
