The study is a multi-center, longitudinal, observational study to describe longitudinal trajectories of Clinician-Reported Outcomes (ClinROs) and Patient-Reported Outcomes (PROs) in patients with select dermatological conditions. This study will collect data using validated clinical instruments and patient-reported data on the disease course of alopecia areata (AA), atopic dermatitis (AD), hidradenitis suppurativa (HS), psoriasis (PsO), and vitiligo (VL), including symptom assessments and quality of life (QoL) measures from a patient perspective, to supplement routine clinical data collected from their healthcare providers. ClinRO data will be collected at baseline and routine follow-up visits for up to two years. PRO data will be collected directly from patients at baseline and at pre-specified follow-up time points (as defined in Tables 1 – 2e) for up to two years.
The objectives of this study are:
- To describe longitudinal changes in disease activity, symptom control and both physical and mental HrQoL based on both ClinROs and PROs
- To identify patient, disease and treatment factors associated with changes in PROs over time
- To describe the association between PROs, ClinROs and clinical outcomes
