Clinical Trial Summary

This is a study in 3 phases that will assess the feasibility and utility of handheld home ultrasound (HHUS) in a patient's home to assess whether a painful episode in the elbow, knee or ankle is a bleed or not.

Description:

This is a study in 3 phases that will assess the feasibility and utility of handheld home ultrasound (HHUS) in a patient's home to assess whether a painful episode in the elbow, knee or ankle is a bleed or not.

Phase 1 will assess whether 10 subjects with severe hemophilia A can be trained to use HHUS in clinic to identify basic joint structures of the elbow, knee and ankle. It will then assess whether these subjects can identify these structures at home and transmit the images life via tele-ultrasound.

Phase 2 will assess whether the determination of "bleed" vs. "non-bleed" made at home via HHUS can be confirmed/validated with a standard high resolution ultrasound machine in clinic.

Phase 3 will then utilize HHUS during the EmiMSKUS study over 3 years to more objectively identify patient reported bleeding during the study.

Inclusion Criteria:

• Severe hemophilia A

• Male

• Over 18 years of age

• Able to read, write and understand English

• Willing to come to the center for an 8 hour training session

• Lives in proximity of the HTC and is willing to come in for acute joint episodes in phase 2

Related Conditions & MeSH terms

• Hemarthrosis
• Hemophilia A
• Joint Bleed

Intervention

Device:
• handheld ultrasound: Philips Lumify integrated tele-ultrasound powered by Reacts collaborative platform
Patients receive training by the physical therapist to operate a handheld ultrasound (HHUS) including proper probe placement. Subjects will be tested on their knowledge at the HTC to demonstrate proficiency, and will then repeat the testing at home via tele-ultrasound.
