New Technology for Acne Evaluations Reliable

JAMA Dermatol; ePub 2017 Dec 20; Singer, et al

Agreement was found between acne evaluations performed in person and from self-photographs by using Network Oriented Research Assistant (NORA), according to a recent study. As a reliable telehealth technology for acne, NORA can be used as a teledermatology platform for dermatology research and can increase access to dermatologic care. This study enrolled consecutive patients with acne vulgaris from a single general dermatology practice in Los Angeles, CA, who were able to use NORA on an iPhone 6 to take self-photographs. Patients were enrolled from January 1 through March 31, 2016. Each individual underwent in-person and digital evaluation of his or her acne by the same dermatologist. A total of 69 patients (37 male [54%] and 32 female [46%]; mean [SD] age, 22.7 [7.7] years) enrolled. Researchers found:

  • The intraclass correlation coefficients of in-person and photograph-based acne evaluations indicated strong agreement.
  • The intraclass correlation coefficient for total lesion count was 0.81; for the Investigator’s Global Assessment, 0.75.
  • Inflammatory lesion count, noninflammatory lesion count, and cyst count had intraclass correlation coefficients of 0.72, 0.72, and 0.82, respectively.
