16604 A retrospective review of delay in diagnosis, severity of disease, and dermatology visits characterized by race in patients with hidradenitis suppurativa in a Midwestern population

Abstract

Hidradenitis suppurativa (HS) is an inflammatory skin condition that disproportionately affects African Americans. We searched the Medical College of Wisconsin and Froedtert Health i2b2 electronic data warehouse, including more than 1.3 million patients in Southeast Wisconsin, for patients with an HS diagnosis and ≥3 encounters for HS using ICD9 705.83 and ICD10 L73.2 codes. We randomly characterized 373 of 1190 identified patients by retrospective chart review, excluding patients without an encounter for HS treatment.
