Brief Summary:
'The PACT trial' is randomized pilot trial to demonstrate the feasibility and potential effectiveness of a personal "fitness tracker" to improve adherence to an activity regimen following an initial acute DVT in children.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Post Thrombotic Syndrome Deep Vein Thrombosis | Device: Fitbit Behavioral: 30-minute education session | Not Applicable |
The feasibility of an innovative intervention of a validated fitness tracker, the Fitbit, to improve adherence to a 12-week activity regimen in a pilot randomized controlled trial (RCT) will be tested in 44 subjects with first, acute, proximal lower extremity deep vein thrombosis (DVT).
The primary outcomes will consist of a) feasibility indicators determined a priori (eligibility, consent, adherence, retention) and b) estimates of effect size associated with the prescribed activity regimen, by describing within-subject change in QoL and potential biomarkers of postthrombotic syndrome (PTS) pre and post intervention in each group.

| Arm | Intervention/treatment |
|---|---|
|
Experimental: Intervention
Participants randomized to the intervention arm will receive a Fitbit, formal 30-minute education session on post-thrombotic syndrome (PTS) and benefits of increased physical activity. An individualized activity prescription will be provided and participants will be asked to maintain the target level of activity for 12 weeks after determining their habitual activity in the first 4 weeks.
|
Device: Fitbit
The Fitbit will be utilized in the intervention arm to improve adherence to a 12-week activity regimen.
Other Name: Activity tracker Behavioral: 30-minute education session |
|
Active Comparator: Control
Participants randomized to the control arm will receive a formal 30-minute education session on post-thrombotic syndrome (PTS) and the benefits of increased physical activity. Their physical activity will be self-reported in an activity log and by the Gordin activity questionnaire over the 16-week intervention period.

Behavioral: 30-minute education session |
Primary Outcome Measures :
- Proportion of screened patients who meet eligibility criteria [ Time Frame: Within 9 months ]Feasibility criteria met when assessed to be ≥ 30%
- Proportion of eligible patients who provide consent [ Time Frame: Within 9 months ]Feasibility criteria met when assessed to be ≥ 30%
- Level of adherence in the FitBit arm [ Time Frame: Within 6 months of randomization ]Feasibility criteria met when assessed to be ≥ 60%
- Proportion of subjects who complete the trial post randomization [ Time Frame: Within 6 months of randomization ]Feasibility criteria met when assessed to be ≥ 80%
Secondary Outcome Measures :
- Change in PTS biomarkers pre and post intervention of increased physical activity as measured by markers of coagulation activation, inflammation and fibrinolysis [ Time Frame: Within 6 months of randomization ]Markers of coagulation activation as assessed by D-dimer, FVIII; inflammation as assessed by C-reactive protein and markers of fibrinolysis as assessed by PAI-1, in addition to global coagulation assays, namely thrombin generation and TEG-fibrinolysis
- Change in Quality of Life [ Time Frame: Within 6 months of randomization ]As assessed by PedsQL instrument
Other Outcome Measures:
- Change in physical activity scores [ Time Frame: Within 6 months of randomization ]As determined by Gordon Questionnaire
- Elastic Compression Stocking (ECS) use assessed by ECS logs [ Time Frame: Within 6 months of randomization ]ECS use will be assessed by ECS log/diary documenting dedicated (use for at least 6 days/week), moderate (use for 4-5 days/week) or poor use (<4 days/week)
