What this Trial Is About
The main aims of this study are to understand why adults with Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) chose a certain treatment, why they changed to HyQvia from another therapy, how satisfied they are with HyQvia and their previous treatment, how their work productivity and activity is impacted and learn about their CIDP signs and symptoms. Other aims are to collect information on any medical problems or side effects during the treatment with HyQvia, learn how effective treatment of CIDP with HyQvia is and understand details on the use of HyQvia in standard clinical routine as well on the need for healthcare intervention (such as emergency room visits or hospital visits or stays). During the study, data will be collected from medical records already available, interviews with participants at study start and study completion and via questionnaires completed by participants. Participants will be treated as per the doctor's or the clinic's routine.
