Case and Use Scenario Study to Gain Knowledge on the User Needs for a Medical Device for Hemophilia a Monitoring

This observational study consists of two parts.

In part one, case scenario focus groups with hemophilia A patients and healthcare providers (HCPs) will be held. This parts aims to identify potential use scenarios of a point of care (POC) in vitro medical for patients with hemophilia A. The main questions it aims to answer are:

* How is coagulation lab testing for patients with hemophilia A currently organized?
* What is the interest and what are desired alternatives of a POC in-vitro diagnostic medical device for patients with hemophilia A?

Part two of the study consists of a use scenario study in which patients with hemophilia A and HCPs will evaluate two types of non-functional mock-ups of a POC in vitro medical device. The main goal of this part is to evaluate the usability of the current prototypes of the POC device.
