Privalle A, et al. - In this investigation, researchers compared biopsy utilization between dermatologists (MDs), dermatology advanced practice professionals (APPs), primary care physicians (PCPs), and other non-dermatology clinicians. During the study period, reports of pathology, requisition forms, and clinical notes of skin biopsies submitted to the institution were reviewed. Skin biopsies for inflammatory conditions, cosmetic or functional purposes, and re-excisions were excluded. The number needed to biopsy (NNB) was calculated as the number of biopsied lesions divided by histologically proven skin cancers. The NNB by clinician type was 2.82 for dermatology MDs, 4.69 for dermatology APPs, 4.55 for non-dermatology PCPs, and 6.55 for other non-dermatology clinicians. Investigators found that dermatology physicians had the lowest NNB of all clinician groups. PCPs had similar performance to dermatology APPs.
