Study Overview
=================
Brief Summary
-----------------
Real-CHOICE - designed as a prospective, longitudinal, observational, non-interventional study - will investigate the attitude of patients and physicians towards IV (intravenous) iron therapy in general and IIM (iron isomaltoside 1000) treatment particularly before and after IIM treatment in iron deficient patients with or without anemia in the real-world clinical setting after commercial availability of this product in Switzerland.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Attitude of patients towards IV iron treatment evaluated with questionnaire. | Rate of patients with stability or positive change in attitude. Questionnaire comprises the following questions: I am hesitant to be treated with IV iron. I would consider IV iron treatment due to the physician ́s choice. I would consider IV iron treatment due to its safety compared to other iron treatment options. I would consider IV iron treatment due to its efficacy compared to other iron treatment options. | Change from baseline taking into account baseline (BL) and follow-up (FU) answers. Follow-up at the latest 12 weeks after observed dosing and before a potential subsequent dosing (if available based on clinical routine follow-up). |
