• Resumen

  • Objective To evaluate the prevalence of comorbid conditions among patients with alopecia areata (AA) seen at tertiary care hospitals in Boston, Massachusetts, during an 11-year period.

    Design Retrospective cross-sectional study.

    Setting Tertiary care hospitals in Boston, including Brigham and Women�s Hospital and Massachusetts General Hospital.

    Participants We identified 3568 individuals with AA seen in the Partners health care system in Boston between January 1, 2000, and January 1, 2011. We performed comprehensive searches of the Research Patient Data Repository using International Classification of Diseases, Ninth Revision code 704.01. We randomly selected 350 patients and manually reviewed their medical records to train and validate a novel artificial intelligence program. This program then used natural language processing to review free-text medical records and confirm a diagnosis of AA. To confirm the algorithm, we manually reviewed a subset of records and found 93.9% validity.

    Main Outcomes and Measures The prevalence of comorbid conditions was assessed.
