Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Advancing the understanding of the relationship between patient physical activity levels, infusion and occurrence of bleeding episodes (BEs) | 6 months retrospectively (after the informed consent form (ICF) is signed) through 6 months | After the informed consent form is signed, retrospective data on physical activity levels, infusion and occurrence of BEs will be collected. The retrospective period will be the 6 months prior to signing the ICF. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Activity measurement | Baseline through 6 months | Including: calories burned, steps taken, distance traveled, and active minutes |
| Infusion schedule for participants on prophylaxis | Baseline through 6 months | — |
| Infusion amount (either ADVATE (Hemophilia A), or RIXUBIS (Hemophilia B) | Baseline through 6 months | — |
| Types of current physical activities of participants | Baseline through 6 months | — |
| Patient-reported outcome: Hemophilia Activities List (HAL) questionnaire - for adult patients | Baseline and 6 months | The HAL measures activities involving the upper extremities, basic activities involving the lower extremities and complex activities involving the lower extremities as well as an overall physical activity score for adults. |
| Patient-reported outcome: pediatric Hemophilia Activities List (pedHAL) questionnaire - for pediatric patients | Baseline and 6 months | The PedHAL measures activities involving the upper extremities, basic activities involving the lower extremities and complex activities involving the lower extremities as well as an overall physical activity score for participants 13-17 years of age: |
| Occurrence of bleeding episodes (BEs) | 6 months retrospectively (after the informed consent form (ICF) is signed) through 6 months | After the informed consent form is signed, retrospective data on physical activity levels, infusion and occurrence of BEs will be collected. The retrospective period will be the 6 months prior to signing the ICF. |
