Abstract: Objective To investigate the prevalence and proportion of geriatric dermatoses of dermatology department. Methods The clinical data of inpatients in the Department of Dermatology of the First Affiliated Hospital of Anhui Medical University from 2017 to 2019 was retrospectively analyzed. Results There were 1598 elderly dermatological inpatients (≥60 years old), accounting for 29.34% of the total dermatological inpatients during the same period, and the ratio of male to female was 1.41∶1. The skin diseases of the elderly inpatients were divided into 18 categories and 48 kinds, among which the top 3 diseases were allergic skin diseases (n=473, 29.60%), viral skin diseases (n=448, 28.04%) and immune bullous diseases (n=228, 14.27%). The inpatients aged 60-69 years old mainly suffered from allergic skin diseases, followed by viral skin diseases; The inpatients aged 70-79 and 80-89 years old mainly suffered from viral skin diseases, followed by allergic skin diseases; The inpatients aged 90 years and over mainly suffered from autoimmune bullous disease, followed by allergic skin disease. Hierarchical analysis showed that the top six skin diseases leading to hospitalization in the elderly were herpes zoster (28.04%), eczema (12.70%), drug eruption (9.64%), bullous pemphigoid (9.51%), psoriasis (7.38%) and urticaria (4.46%). Among them, eczema and psoriasis were more common in male patients, while herpes zoster, drug eruption and urticaria were more common in female patients. In addition, there were significant differences in the prevalence rates of above skin diseases between elderly patients and pre-aged patients (45-59 years old). Conclusions Elderly dermatological inpatients account for nearly 1/3 of the total number of dermatological inpatients during the same period, and there are significant differences in the distribution of skin diseases among different genders and different ages.
