Wearable Technology to Reduce Risk of DVT and Increase Patient Compliance (SBIR2)
Study Overview
Detailed Description
DVT is the most feared complication of total joint replacement (TJR), with more than 300,000 total hip and 700,000 total knee replacements performed annually in the U.S. Current recommendations for postoperative DVT prophylaxis after TJR include anti-coagulant medications and/or intermittent pneumatic compression (IPC) of the lower limb for a minimum of 10-14 days. Most current IPC devices are non-mobile, making early postoperative mobility, which is especially important in TJR patients, cumbersome and time-consuming. Upon hospital discharge, most patients go home on pharmacologic DVT prophylaxis. Even when at-home external compression therapy is prescribed (IPC or compression stockings), data suggests compliance rates as low as 10-50%.
Recovery Force (RF) has produced the next generation of mechanical DVT prophylaxis, with a mobile device absent of tubes and pumps, stays in place during ambulation, is lightweight and comfortable for continuous wear, and is designed to improve compliance with recommended use. The hypothesis for Phase II is that IPC using the RF1400 will result in improved compliance, support early mobility and result in significantly higher functional mobility after TJR as compared to standard of care.
The research team will conduct a randomized comparative study of DVT prophylaxis using either standard IPC (Group 1) or the RF1400 (Group 2) in 300 patients after TJR surgery. Dr. Karen Giuliano of the University of Massachusetts Amherst will serve as the overall PI for efforts associated with the study sites. This study will include an inpatient phase and an outpatient phase with patients at two clinical sites: Tufts Medical Center and Indiana University School of Medicine, with each site enrolling 150 patients (75 control/75 experimental).
The overall goal of Phase II is to demonstrate that compliance with perscribed use, comfort, and ease-of-use is significantly higher with the RF1400 than with DVT prophylaxis using either standard IPC (in-hospital) or standard-of-care (at-home) in preparation for full commercialization in the TJR market during Phase III. The DVT therapy market is expected to hit $3.8B by 2021, and the US accounts for over 50% of the global market. With the current risk of bleeding from anticoagulant DVT prophylaxis at 5.6%, the commercial impact of this research is that improved patient compliance with the RF1400 DVT prophylaxis will improve postoperative mobility and provide an effective alternative to anticoagulation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Standard of Care
Participants will receive DVT prophylaxis using standard intermittent pneumatic compression during postoperative care after total joint replacement.
|
|
Experimental: Recovery Force MAC
Participants will receive DVT prophylaxis using the RF Health MAC during postoperative care after total joint replacement.
|
The RF Health MAC is a novel device that is applied to the lower legs of patients that provides intermittent active compressions to the calf muscles which results in increased blood flow in the veins, moving blood towards the direction of the heart and reducing the risk of clot formation.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Compliance to prescribed use
Time Frame: 18 months
|
Compare patient compliance (measured as percent of time used per 24-hour period) between the standard of care sequential compression device and the Recovery Force Mobility and Compression (MAC) system in a group of total joint replacement patients.
|
18 months
|
Patient-reported comfort
Time Frame: 18 months
|
Compare patient-reported comfort (using the comfort rating scale, score 1-10 where higher score=greater comfort) between the standard of care sequential compression device and the Recovery Force Mobility and Compression (MAC) system in a group of total joint replacement patients.
|
18 months
|
Patient-reported ease-of-use
Time Frame: 18 months
|
Compare patient-reported ease-of-use (using the System Usability Scale, with a range of 0-21, where higher score =higher ease of use) between the standard of care sequential compression device and the Recovery Force Mobility and Compression (MAC) system in a group of total joint replacement patients.
