Privalle A, et al. – Researchers analyzed pathology reports, requisition forms, and clinical notes of skin biopsies to compare biopsy use among dermatologist physicians, dermatology advanced practice professionals (APPs), primary care physicians (PCPs), and other nondermatology clinicians. The number needed to biopsy (NNB) by clinician type was 2.82, 4.69, 4.55, and 6.55 for dermatology physicians, APPs, nondermatology PCPs, and for other nondermatology clinicians, respectively. Between clinician groups for nonmelanoma skin cancer, the NNB was significant, but not for melanoma. Therefore, of all clinician groups, dermatology physicians had the lowest NNB. Moreover, PCPs performed similarly to dermatology APPs.
