Remote Blood Pressure Monitoring Reduces Recurrent Stroke Risk

    A novel post-acute stroke care initiative employing telehealth to monitor patients’ blood pressure at home is showing positive results among patients living in under-resourced communities.

    “Hypertension is the most important modifiable risk factor for a second or recurrent stroke,” says Imama A. Naqvi, MD, a neurologist in the Division of Stroke and Cerebrovascular Disease at NewYork-Presbyterian/Columbia University Irving Medical Center, who developed the initiative – Telehealth After Stroke Care (TASC). “We know that a small change to lower systolic blood pressure reduces recurrent stroke risk by more than 20 percent, yet blood pressure is poorly controlled among more than half of stroke survivors. We also know that Black adults have a higher prevalence of uncontrolled blood pressure. Additionally, Black and Hispanic populations have a higher risk of stroke, and the highest increase in stroke prevalence is expected to be among Hispanic males.”

    According to Dr. Naqvi, community programs can address disparities among Black and Hispanic patients regarding home blood pressure telemonitoring and nurse care management. However, in post-acute stroke care, home blood pressure monitoring with custom infographics and multidisciplinary telehealth visits that include pharmacists has not been studied integrated into healthcare systems that care for underserved urban communities.

    Since the COVID-19 pandemic, telemedicine has significantly expanded access to care, but there remain obvious disparities among vulnerable populations. Blood pressure telemonitoring has shown potential in decreasing blood pressure, and multidisciplinary team-based care has also demonstrated to be an effective approach in the general population.

    Dr. Naqvi, whose clinical expertise includes post-acute stroke care and research that is focused on secondary stroke prevention strategies and biomedical informatics approaches to mitigate inequities among diverse stroke populations, developed an innovative multidisciplinary team-based model, including nursing, pharmacy, and physicians – Telehealth After Stroke Care – integrated with home blood pressure monitoring and education in the form of patient-tailored visual information. “Our goal was to establish the feasibility of the intervention in empowering self-management by providing accessible integrated services, equipment, and educational materials,” says Dr. Naqvi, who collaborated with Mitchell S.V. Elkind, MD, MS, Chief of the Division of Neurology Clinical Outcomes Research and Population Sciences, and Olajide Williams, MD, MS, Chief of Staff of the Department of Neurology at NewYork-Presbyterian/Columbia. Dr. Naqvi served as lead author of the study, which was published online in the October 31, 2022, issue of Stroke.

    In the investigation, 50 patients were enrolled from NewYork-Presbyterian/Columbia’s Comprehensive Stroke Center in Northern Manhattan that serves a primarily under-resourced community. Some 44 percent of participants were Hispanic, and 32 percent were non-Hispanic Black. Women comprised 36 percent with a mean age of 64.3 years. Patients included were those who experienced an acute ischemic or hemorrhagic stroke and were diagnosed with hypertension before being discharged home after hospitalization.

    Mobile health tools such as wireless blood pressure devices that enable remote monitoring are here to stay, and we need to find ways to utilize telemedicine to improve care for all stroke survivors.

    Usual Care versus Telehealth After Stroke Care

    In the study, acute stroke patients with hypertension were randomized at discharge to a control group receiving usual care and to the study cohort receiving usual care with TASC. Patients in the control group had a video conference appointment with a primary care professional 1 to 2 weeks after hospital discharge and video conference appointments with a stroke specialist at 6 and 12 weeks after discharge.

    Patients assigned to the TASC intervention with usual care received:

    • A tablet and monitor to wirelessly transmit BP data to the electronic health record
    • Video visits with nursing and pharmacy support
    • Plain language blood pressure infographics in English and Spanish to explain readings

    Participants’ readings were sent to their electronic health record and, if needed, a nurse provided telephone support and could escalate the call to telepharmacists and physicians.

    Key findings from the study included:

    • The Telehealth After Stroke Care strategy saw a dramatic improvement in patient follow-up: 84 percent of patients in the TASC group completed the 12-week study, compared to 64 percent of patients in the usual care group.
    • 91 percent of patients in the enhanced telehealth group completed the video visit with primary care professionals and specialists, compared to 75 percent of patients in the usual care group.
    • Blood pressure control was better in the enhanced telehealth group at 76 percent, compared to 25 percent control in the control group.
    • Among Black study participants, blood pressure control improved from 40 percent of participants at enrollment to 100 percent at the study’s conclusion in the TASC group and improved only from 14 percent to 29 percent in the control group.

    Dr. Naqvi and NewYork-Presbyterian/Columbia neurological faculty presented the results of their feasibility study at the American Stroke Association International Stroke Conference in February 2022. “This new research will continue to strengthen our work and commitment to addressing health inequities by focusing on blood pressure through regular remote monitoring and partnering with our patients,” noted Willie Lawrence, MD, Chairman of the American Heart Association’s National Hypertension Control Initiative’s Oversight Committee.

    “Mobile health tools such as wireless blood pressure devices that enable remote monitoring are here to stay, and we need to find ways to utilize telemedicine to improve care for all stroke survivors,” adds Dr. Naqvi. “As physicians, we want to provide patients with equitable access to care and find the right post-stroke care interventions that engage patients and improve health outcomes.”
