mHealth Screening to Prevent Strokes (mSToPS)

November 8, 2022 updated by: Steven Steinhubl, Scripps Translational Science Institute

mHealth Screening to Prevent Strokes (mSToPS)

The purpose of this study is to investigate whether it is possible to identify a high-risk cohort suitable for screening for asymptomatic atrial fibrillation using claims data, and then engage those individuals in a mobile health technology-enabled home monitoring program in order to document previously undiagnosed atrial fibrillation, and provide clinical evidence of an outcomes benefit associated with this early detection.

Conditions

Detailed Description

The purpose of this study is to propose to study two different methods of intermittent rhythm monitoring in a cohort of individuals without prior history of atrial fibrillation, but determined to be at increased risk based on clinical risk factors, and compare the rate of atrial fibrillation detection through monitoring relative to routine care.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Immediate Monitoring

Individuals randomized to immediate monitoring will receive the ZIO XT patch sensor and wear it for the first and last 2 week period of the 4 month monitoring period of time 0 to 4 months.

Note: Approximately 250 consenting participants will also be invited to participate in a sub-study to wear an additional monitoring device (Amiigo wristband) continuously over the 4 month monitoring period.

Single-lead ECG monitoring via a wearable patch
Determines pulse rate using photoplethysmography.
Active Comparator: Delayed Monitoring

Individuals randomized to delayed monitoring will receive usual care for 4 months after which they will receive the ZIO XT patch sensor and wear it for the first and last 2 week period of study months 4 through 8.

Note: Approximately 250 consenting participants will also be invited to participate in a sub-study to wear an additional monitoring device (Amiigo wristband) daily for months 4 through 8.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of Newly Diagnosed AF in the Immediate vs Delayed Monitoring Group
Time Frame: End of 4 month monitoring period
Incidence of newly diagnosed AF as defined by at least 30 seconds of AF or atrial flutter at the end of the 4 month monitoring period compared to the delayed monitoring cohort (primary) and observational control (secondary)
End of 4 month monitoring period

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of Atrial Fibrillation in Both Monitoring Groups Versus the Matched Controls
Time Frame: 1 year
In the observational study, over 12 months of follow-up, we looked at the prevalence of AF in the actively monitored and delayed monitored cohorts.
