Clinical Trial Summary

This study will prospectively compare compliance rates between a novel FDA cleared wearable compression therapy with and without digital engagement for DVT prophylaxis in both hospital and home environments after total knee or hip arthroplasty.

Description:

This study is a single-arm, open-label, prospective, single-center study designed to evaluate compliance to CirvoTM therapy use with and without digital engagement. Historical questionnaire data with a different compression device will be compared to the same questionnaire used for the prospective cohort of up to 200 subjects. All patients prescribed compression therapy following total joint arthroscopy will be offered participation. Subjects will receive CirvoTM compression therapy according to the standard of care protocol at NYU during or after surgery and 18 hours per day for 14 days. 1. Baseline: Following consent, participants will provide demographic, medical history and information with respect to their elective orthopedic procedure and receive training on the CirvoTM device. Participants will be randomized to either digital engagement or no digital engagement groups. 2. Post procedure: After the procedure, CirvoTM device operation will be reviewed with the participant. 3. Discharge: Any adverse events occurring during hospitalization will be reviewed, data capture on the CirvoTM app will be confirmed. 4. 14- day visit: Participants will complete a patient satisfaction questionnaire, provide information with respect to any adverse events including specific details about DVT and readmission and return the devices. 5. 30-day phone call/visit: Participants will be contacted at 30 days to answer questions about DVT's and readmissions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in compliance using Cirvo compression therapy	A sample size of 100 subjects is powered at 90% to show a difference of 10% in compliance between the 2 digital engagement cohorts. For each subject, Compliance will be calculated for each participant during the course of therapy in terms of the number of hours of actual use/number of hours of prescribed use. The number of hours will be summarized as days of use for each group.; The means of each group will be presented. The primary endpoint is the difference in compliance between the group assigned to digital engagement versus no digital engagement with the Cirvo app. The mean difference will be compared to zero using the paired t-test	14 day visit (+7 days)
Secondary	Change in patient satisfaction using Cirvo compression therapy	A comparison between the satisfaction of CirvoTM therapy versus the historical data from comparator device use will be performed. Results of the usability questionnaire (Patient Satisfaction Intermittent Compression Devices Questionnaire) will be qualitatively summarized.	14 day visit (+7 days)
Secondary	Change in staff satisfaction using Cirvo compression therapy.	A comparison between the satisfaction of CirvoTM therapy versus the historical data from comparator device use will be performed. Results of the usability questionnaire will be qualitatively summarized. Staff Satisfaction Intermittent Compression Devices Questionnaire will be administered.	14 day visit (+7 days)
Secondary	Change in patients satisfaction using Cirvo compression therapy	A comparison between the satisfaction of CirvoTM therapy versus the historical data from comparator device use will be performed. Results of the usability questionnaire (Patient Satisfaction Intermittent Compression Devices Questionnaire) will be qualitatively summarized.	30 day visit
