Physician selection:
Identification of the physicians via a sampling base consisting of: - The French Hematologists' Directory, - The list of accredited centers, - Internal Medicine departments, A random sample of 1 000 physicians will be extracted from the base. The database will be previously reduced in order to point physicians who manage ITP of adults. 4.4 Patient sample size ITP is a rare disease. In consequence, calculation of the number of subjects needed is based more on the feasibility of recruitment in an acceptable timeframe than on a hard assessment criterion. In view of the incidence and prevalence of ITP and our estimates, recruitment of 200 patients by 60 to 70 participating physicians (active centers) constitutes a feasible objective. However, given that it is highly probable that the patients treated with TPO-R agonists mainly receive care in reference or accredited centers, the participating physicians will be asked to include 3 to 8 patients at TPO-R |
| Database objective | |
| Main objective | Describing the profile of patients with chronic ITP treated with TPO-R agonists and the clinical course of their disease over 2 years |
| Inclusion criteria |
Each participating physician is to include in a cross-sectional registry the first patients who are managed for their ITP persistent or chronic. Each physician could fill information about 15 patients maximum.
Among the maximum of 15 patients included in the cross-sectional registry, each participating physician is to include in the cohort, in a consecutive manner, the first 3 to 8 patients with chronic ITP at TPO-R agonist treatment initiation in compliance with the inclusion criteria |

| Procedures | |
| Data collection method | Throughout the study, data acquisition will be implemented via an electronic CRF (e-CRF). In order to analyze the time course of the quality of life and satisfaction of patients with chronic ITP treated with a TPO-R agonist, a quality of life and satisfaction questionnaire will be supplied to the patients taking part in the study |
| Participant monitoring |
Yes |
| Details on monitoring of participants | In order to achieve the primary objective, the physicians will be asked to fill out the e-CRF at time points: M0, M3, M6, M12, M18 and M24 |
