Psychiatric comorbidities on an inpatient dermatology consultation service: A cross‐sectional analysis

Abstract

AbstractDespite the high prevalence of psychiatric illness in hospitalised dermatology patients, characterisation of psychiatric comorbidities on an inpatient dermatology consultation service in the United States has yet to be performed. To fill this gap in knowledge, we investigated the prevalence of and factors associated with psychiatric illness on the inpatient dermatology consultation service at the University of Southern California. Of the 429 patients seen by the dermatology consultation service between June 2021 to July 2022, 147 (34%) had psychiatric illness (defined as having at least 1 psychiatric diagnosis). Increasing age was associated with a decreased likelihood of psychiatric illness, while housing instability, chronic dermatologic disease, drug reaction, and pruritus without rash were associated with an increased likelihood of psychiatric illness. The high prevalence of psychiatric illness observed in hospitalised dermatology patients emphasises the importance of collaboration between consultant dermatologists and mental health specialists, particularly when specific sociodemographic or disease factors are present.
