TEC4Home Stroke - Feasibility of Home Telemonitoring Technology in Managing Hypertension Among Stroke/TIA Patients
Study Details
Study Description
Brief Summary
This study will test the feasibility of a home blood pressure telemonitoring (HBPTM) system in patients with minor stroke or TIA in the past year. The telemonitoring system will consist of a blood pressure machine and an online survey to submit blood pressure measurements. The investigators want to test whether patients can persistently use the telemonitoring system with ease and whether telephone instructions for blood pressure medications from the research nurse can be correctly understood. A secondary purpose of this study is to look at the effects of telemonitoring in blood pressure and stroke recurrence.

Detailed Description
The investigators propose a two-year pilot study (TEC4Home Stroke) to assess the feasibility of using home telemonitoring technology in managing hypertension among patients with minor stroke/TIA (NIH Stroke Scale Score <5) at the VGH Stroke Prevention Clinic (SPC). The Vancouver Stroke Program SPC receives 1200 referrals per year for assessment of patients with strokes or TIAs. Of the total number of patients referred to the SPC, 45% were deemed as hypertensive patients through any one of: (1) medical history of hypertension, (2) on antihypertensive medications or (3) having blood pressure measurements above 140/90 mm Hg during their assessment at the clinic.
This project, which includes baseline assessments of home supports and cognition, will assess the specific needs of the post-stroke population in determining feasibility of HBPTM and nurse-led hypertension treatment. Previous studies of aggressive hypertensive control regimens have shown that it takes approximately six months to consistently achieve target pressures (SPRINT, SPS3). Thus in this feasibility study, participants will be monitored for 6 months using home telemonitoring technology.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
TEC4Home Stroke Cohort All participants or caregiver involved will be instructed to measure BP per the TEC4Home BP Telemonitoring Protocol. Participants will measure their BP daily, 4x/day, for the first week. After the first week, all weekly BP measurements will be done 3 days/week with 4 measurements a day. All readings must be taken before administration of antihypertensive medications, twice in the morning, 5 minutes apart and twice in the evening, 5 minutes apart. The TEC4Home telemonitoring nurse will review the BP measurements and contact the participant on a weekly basis until the end of the 6-month monitoring period. The telemonitoring nurse will adjust the antihypertensive medication doses as per the TEC4Home Stroke - Hypertension Management Algorithm. |

- GP feedback on the Telehealth program [At the six-month (180 day) time point. We welcome feedback from the participant's GP during the 6 month study period.]
The participant's GP, if they have one, will be contacted with information regarding their patients' participation and the CHEP-guided management algorithm. The GP will receive a summary of the follow-up phone calls by the Telehealth nurse and notes from in-person follow-up study visits. We will ask GPs to inform us via fax or email after any patient follow-up visit and to additionally touch base if there are concerns about the current medication regimen or if changes are made. At the end of the study, GPs will receive an exit questionnaire regarding their experience in managing their patients during the telehealth program and inviting suggestions for future GP/community health engagement.
