dents in 5 of 6 vignettes. For all vignettes with a higher risk 31-GEP test result, there was a statistically significant increase in SLNBx recommendations.Impact of 31-GEP Test Results on Decision to Recommend X-Ray or Ultrasound A lower risk 31-GEP test result led to a statistically significant decrease in recommended imaging with x-ray or ultrasound in 5 of 6 vignettes. For all vignettes, a higher risk 31-GEP test result led to a statistically significant increase in the proportion who would recommend x-ray or ultrasound imaging.Impact of 31-GEP Test Results on the Decision to Recommend CT, MRI, or PET Scan A lower risk 31-GEP test result led to a statistically significant decrease in recommended imaging with CT, MRI, or PET scans in 5 of 6 vignettes. For all vignettes with a higher risk 31-GEP test result, there was a statistically significant increase in CT, MRI, or PET scan recommendations.Impact of 31-GEP Test Results on Recommended Follow-up Interval A lower risk 31-GEP result led to a statistically significant increase in the number of respondents who would recommend a longer follow-up interval in 4 of 6 vignettes. Similarly, a higher risk result was associated with a statistically significant increase in the proportion who would recommend shorter follow-up interval for all vignettes.
DISCUSSION
In order to be clinically useful, a new technology or test must impact management.Previous studies have demonstrated the impact and clinical utility of a 31-GEP assay on management decisions made by dermatologists and residents.11,12 The present study produced similar results in another group, dermatology PA/NPs, who may have less experience in pigmented lesion assessment and thus may gain even greater benefit from this adjunctive technology.
