About this study

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.

Read the detailed 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • handheld ultrasound: Philips Lumify integrated tele-ultrasound powered by Reacts collaborative platformDevice

    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.

  3. Outcome 1.3: Participating subjects can perform what they learned during their training at the HTC in outcome 1.1 and outcome 1.2 at home and transmit images to the HTC.

    Number of participating subjects who can perform what they learned during their training at the HTC in outcome 1.1 and outcome 1.2 at home and transmit images to the HTC on post-training test.

    Measured: 3 months

  4. Outcome 2.1: Subjects will be able to attain and transmit images of their joint spaces to the HTC via telemedicine utilizing the HHUS technology they learned in phase 1 and React App.

    Number of subjects who will be able to attain and transmit images of their joint spaces to the HTC via telemedicine utilizing the HHUS technology they learned in phase 1 and React App.

    Measured: 6 months

  5. Outcome 2.2: Accuracy of the assignment of "bleed" vs. "non-bleed" will be determined on the stationary GE LS8 Logiq Pro in the HTC.

    Percentage accuracy of the assignment of "bleed" vs. "non-bleed" will be determined on the stationary GE LS8 Logiq Pro in the HTC.

    Measured: 6 months

  6. Outcome 3.1: To establish how accurate patient reported bleeding is compared to HHUS utilizing tele-ultrasound.

    Percentage accuracy of patient reported bleeding is compared to HHUS utilizing tele-ultrasound.

    Measured: 3 years

  7. Outcome 3.2: To establish more accurate bleeding data for the EmiMSKUS study.
