Clinical Trial Summary

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.

Intervention

Other:
• Case scenarios - questionnaire
Participants fill in a questionnaire on the current care of hemophilia A and envisioned use scenarios of a point-of-care diagnostic device for hemophilia A.
• Case scenarios - Focus groups
Participants partake in focus groups on the current care for hemophilia A, the envisioned use scenarios of point-of-care diagnostic device for hemophilia A and desired features of such a diagnostic device.
• Use scenarios - Usability test
Participants are asked to perform basic tasks with the mock-ups with minimal instructions, they will also be given a graphic of the user interface (GUI).
• Use scenarios - interview
The participants will be interviewed and asked for their opinions and experiences with the mock-ups.
