What this trial studies

This project aims to establish a national registry for patients suffering from chronic pruritus (itch) in Switzerland. Participants will undergo comprehensive assessments including patient-reported outcomes, physician evaluations, blood tests, and imaging techniques at specified intervals. The registry will facilitate a better understanding of patient needs, treatment outcomes, and safety issues related to chronic pruritus. Additionally, it will enable standardized comparisons of various pruritic conditions and enhance awareness among healthcare providers and authorities.

Who should consider this trial

Good fit: Ideal candidates for this registry are individuals aged 14 and older with a diagnosis of chronic pruritus and a minimum itch severity score.

Not a fit: Patients with conditions that prevent them from participating in the registry or those who refuse to complete necessary assessments may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could significantly improve the management and treatment of chronic pruritus, leading to better patient outcomes.

How similar studies have performed: While this approach is novel in Switzerland, similar registries have shown success in other countries, indicating potential for impactful outcomes.
