Key clinical point: Although rates of principal psoriasis hospitalizations have decreased among patients with psoriasis in the last 2 decades in the United States, hospitalization for non-psoriatic reasons has increased, which may be attributed to increased comorbidity burden driving admissions because of comorbidities.
Major finding: Between 1998 and 2018, the incidence of hospitalizations with either principal or secondary diagnosis of psoriasis increased from 17.9 to 52.0 per 100,000 persons, the proportion of patients with psoriasis hospitalized with psoriasis as principal diagnosis reduced from 4.1% to 1.0%, and those with Charlson Comorbidity Index score of 3 or higher increased from 13.9% to 30.9% (all adjusted P-trend < .0001).
Study details: This was a 21-year longitudinal trend analysis of the National Inpatient Sample database between 1998 and 2018 including adults with a principal or secondary diagnosis of psoriasis.
Disclosures: The study did not receive any funding. The authors declared no conflict of interests.
