FARD (RaDiCo Cohort) (RaDiCo-FARD)

Study Overview
=================
Brief Summary
-----------------
The goal of this observational study is to conduct a prospective assessment of the individual Burden of 9 rare skin diseases to assess disability in the broadest sense of the term (psychological, social, economic and physical) for patients and/or families. Two types of indicators will be used to reach this objective : an individual burden score calculated based on a burden questionnaire created specifically, approved and designed to understand the tendency to changes in care and lifestyles. The burden questionnaire should be used by patients and/or their family themselves in self-assessment. a descriptive analysis of all resources (medical and non-medical) used by the family unit to manage the disease.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Individual burden score for each selected rare disease | Before 16 years old, we will focus on the burden of families. After 16 years old, the patient's parent will continue to answer to the family Burden questionnaire and the patient will start to answer to the adult's Burden questionnaire. | Through study completion, an average of 5 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Description of calculated scores based on widely used survey completed by patients |  | Through study completion, an average of 5 years | 
| Description of calculated scores based on widely used survey completed by parents |  | Through study completion, an average of 5 years | 
| Description of variations of quality-of-life scores. |  | Through study completion, an average of 5 years | 
| Validation of the clinical severity score for disease which have none at the beginning of the study and description of clinical severity score. |  | Through study completion, an average of 5 years | 
| Descriptive analysis of the socio-economic Burden. |  | Through study completion, an average of 5 years | 
| Descriptive analysis of the Individual Health Care Cost. |  | Through study completion, an average of 5 years | 
| Search for association between individual burden score and clinical severity of the disease. |  | Through study completion, an average of 5 years |
