Chronic Pruritus in Geriatric Patients: Prevalence, Associated Factors, and Itch-related Quality of Life.

Abstract

Chronic pruritus is a common condition that significantly impacts quality of life. However, data on chronic pruritus in geriatric populations remain limited. A prospective observational study was conducted at the Centre for Geriatrics in Southern Saxony-Anhalt (ZASSA), involving 201 geriatric patients (mean age 83.5±5.1 years). Chronic pruritus was found in 23.4% of patients, persisting for an average of 8 years with moderate to severe intensity (mean=6.36 on a 0 to 10 numeric scale). It commonly affected the legs (48.9%) and arms (44.7%) and was linked to depressive symptoms and daily medication use. Chronic pruritus significantly impaired physical functioning, particularly in moderate activities and stair climbing, and increased pain levels. ItchyQoL scores highlighted adverse effects on symptoms, functioning, feelings, and self-perception. Overall, chronic pruritus is prevalent among geriatric patients and substantially reduces quality of life. Addressing both dermatological and psychological factors is essential for effective management and improving quality of life in this population.
