Reasons for Hospitalization of Psoriasis Patients: A Report From the National Inpatient Sample

Abstract

Background We used a large United States population-based database to analyze the reasons for hospitalization of psoriasis patients. Methods International Classification of Diseases, 10th revision (ICD-10) code was used to identify hospitalizations in National Inpatient Sample (NIS) 2017 with a principal or secondary diagnosis of psoriasis. The reasons for hospitalization were divided into 19 categories based on their principal discharge ICD-10 diagnosis code. We also ranked the five most common specific reasons for hospitalization of psoriasis patients. Results There were over 35 million discharges included in the 2017 NIS database. A total of 165215 hospitalizations had either a principal or secondary ICD 10 code for psoriasis. Based on ICD-10 code categories, the top five reasons for hospitalization in patients with history of psoriasis were: Cardiovascular (CV) (26605, 16.10%), rheumatologic (19555, 11.84%), digestive (18465, 11.18%), infection (16395, 9.92%), and respiratory (14865, 9.00%). Sepsis was the most common principal diagnosis of psoriasis hospitalizations. Conclusion CV diseases were the most common ICD category, and sepsis was the most common principal diagnosis for psoriasis hospitalization. Management of medical co-morbidities is important in reducing rates of hospitalization of psoriasis patients.
