Swiss Itch Registry (SWITCHR) - A Prospective Registry to Collect Data of Patients With Chronic Pruritus

What this Trial Is About

This research aims to create a national registry for patients with chronic pruritus (CP), which is a persistent itch lasting more than 6 weeks and linked to various skin and non-skin conditions. Chronic pruritus significantly affects quality of life and carries a high socio-economic burden. The registry will help improve medical care, enable standardized comparisons of different pruritic conditions nationally and internationally, and raise awareness among healthcare providers and authorities in Switzerland. Participants in this observational study will have various data collected at defined times, including patient-reported outcomes, physician assessments, blood tests, and 3D photodocumentation. Additional tests like skin biopsies, neurophysiological evaluations, and radiological imaging may be performed if needed. The study focuses on gathering clinical, biological, and image-based data to understand patient needs, disease mechanisms, treatment results, and safety aspects. During the study, participants will be monitored up to 60 months with assessments involving questionnaires measuring quality of life, itch severity, sleep disturbances, anxiety, and skin condition severity. Researchers will also use imaging and sensory testing to track changes over time. The long-term data will support retrospective analyses, with ongoing evaluation of treatment outcomes and patient health status throughout the study period.
