BACKGROUND - OBJECTIVES - METHODS - RESULTS - CONCLUSIONS; Several patient-reported outcome measures (PROMs) have been developed for research to assess the multiple dimensions of chronic pruritus (CP). The acceptability and perceived benefits of their use in clinical practice remain unknown.; To assess the acceptability and perceived benefits of validated PROMs from the perspective of patients and physicians in dermatological offices and clinics.; Patients with CP due to atopic dermatitis, psoriasis, chronic prurigo or chronic urticaria were recruited at 10 dermatological offices and two dermatological clinics in Germany. Patients completed a set of validated PROMs on pruritus intensity (numerical rating scale, NRS), symptom control (itch-controlled days, ItchCD), quality of life (Dermatology Life Quality Index, DLQI; 5-pruritus life quality, 5PLQ) and general health status (EuroQol, EQ-VAS). Acceptability (relevance, difficulty of completion, length) and benefits (usefulness, feasibility) of these tools were assessed on a NRS (0-10) by patients and physicians, respectively. Data were analysed descriptively. Linear regression was used to study potential associations between age, sex, occupation, office versus clinic, change of therapy and physician-reported benefits.; N = 523 patients (46% male, average age: 53.5 years) participated. Acceptability of PROMs by patients was high, indicated by low difficulty (Md = 0, IQR = 0-1 for all PROMs) and high relevance (Md = 8, IQR = 4-10 for all PROMs). Also, most patients (89-95%) rated length of the questionnaires as 'exactly right'. Physicians rated the NRS as the most beneficial instrument (feasibility: Md = 8, IQR = 6-10; usefulness: Md = 9, IQR = 7-10). Hierarchical linear regression revealed that only recruitment site (dermatological office vs. clinic) was significantly associated with usefulness and feasibility (higher ratings for clinical context; βs = 0.149-0.258, ps <0.05; except feasibility for EQ5d, β = ns).; PROMs are welcomed by patients, while physicians consider instruments measuring pruritus intensity and impairment of quality of life as beneficial for the clinical routine. Widespread implementation of PROMs in daily clinical work is needed to improve care.
