Trial Summary

What is the purpose of this trial?

This trial tests a mobile health program called OPTIMA-BP that helps older African American adults manage their high blood pressure. The program uses smartphones and text messages to remind patients to take their medications and follow healthy habits. The goal is to improve blood pressure control and overall health in this high-risk group.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it requires that you are already prescribed at least two antihypertensive medications, including a diuretic or calcium channel blocker.

What data supports the effectiveness of the OPTIMA-BP Intervention treatment for high blood pressure?

Research shows that home blood pressure telemonitoring, which is a key component of the OPTIMA-BP Intervention, helps people better control their blood pressure and feel more satisfied with their care. This approach uses technology to track blood pressure at home and has been linked to improved blood pressure management. ^{1 2 3 4 5}

Is the Technology Intervention for High Blood Pressure safe for humans?

Home blood pressure telemonitoring, a component of the intervention, is generally safe and associated with improved blood pressure control and patient satisfaction. However, more research is needed to fully understand its long-term safety and effectiveness. ^{1 3 6 7 8}

How is the OPTIMA-BP Intervention treatment for high blood pressure different from other treatments?

The OPTIMA-BP Intervention is unique because it uses technology to monitor blood pressure at home and involves telemonitoring, which allows healthcare professionals to remotely track and adjust treatment. This approach can improve patient compliance and blood pressure control by providing real-time feedback and support, unlike traditional methods that rely solely on in-person doctor visits. ^{4 5 9 10 11}

Eligibility Criteria

This trial is for African American individuals over 50 with high blood pressure (BP≥130/80 but <160/90 mmHg), taking at least two BP medications including a diuretic or calcium channel blocker, and who own a smartphone. It's not for those who've had major cardiovascular events in the past year, have cognitive impairments, use other medication apps, show high BP variability, or have severe kidney disease.

Inclusion Criteria

Self-identify as African American

My blood pressure is between 130/80 and 160/90 mmHg.

Exclusion Criteria

I have chronic kidney disease or am on dialysis.

I am able to understand and consent to my treatment.

I had a major heart event or surgery in the last year.

Interventions

• OPTIMA-BP Intervention (Behavioral Intervention)

Trial Overview The OPTIMA-BP trial tests an intervention using mobile health technologies to improve medication adherence and manage high blood pressure among older African Americans. The study aims to see if this tech-based support can help control BP better and reduce health disparities.

Participant Groups

Group I: Intervention: OPTIMA-BP Implementation Experimental Treatment 1 Intervention

Participants randomized to OPTIMA-BP intervention for 6 months then observed for a 6 month follow up period

Group II: Waitlist: OPTIMA-BP implementation Active Control 1 Intervention

Participants randomized to waitlist for 6 months, then offered the OPTIMA-BP intervention for 6 months.

Clinical usefulness and cost effectiveness of home blood pressure telemonitoring: meta-analysis of randomized controlled studies. Omboni, S., Gazzola, T., Carabelli, G., et al.[2023]

A study involving 236 hypertensive patients found that antihypertensive treatment guided by telemonitoring of home blood pressure was as effective as traditional office-based monitoring in reducing systolic daytime blood pressure over 6 months.

Both groups experienced significant decreases in blood pressure, with the telemonitoring group showing a reduction of -11.9 mmHg compared to -9.6 mmHg in the control group, indicating that home monitoring can be a viable alternative for managing hypertension.

Home-based blood pressure telemonitoring has been shown to effectively reduce blood pressure levels and improve patient satisfaction, making it a valuable tool for managing hypertension.

Further research is necessary to evaluate the cost-effectiveness and long-term clinical outcomes of home-based blood pressure monitoring, especially when combined with behavioral modifications and medication management.

The role of home blood pressure telemonitoring in managing hypertensive populations. Zullig, LL., Melnyk, SD., Goldstein, K., et al.[2023]

A study involving 232 patients with mild-to-moderate hypertension showed that home blood pressure monitoring (HBPM) significantly reduced therapeutic inertia (TI) compared to standard care, with TI rates dropping from 50% in the control group to 25.23% in the intervention group by the final visit.

The intervention was effective in managing hypertension, as evidenced by a mean number needed to intervene (NI) of 4.3, indicating that for every 4.3 patients monitored at home, one less experienced therapeutic inertia.

Patients showed a significant increase in their knowledge of blood pressure and comfort with technology after using a Bluetooth-enabled BP monitor and receiving weekly telehealth counseling from pharmacists during a 6-week study involving 12 participants.

The study suggests that integrating Bluetooth BP monitors with pharmacist interventions can enhance blood pressure control and improve patient outcomes, as evidenced by positive patient feedback and improved lifestyle modifications.

Ambulatory blood pressure monitoring (ABPM) studies can accurately measure blood pressure changes over 24 hours in patients with cardiovascular risk, providing valuable data for assessing the safety of chronic medications.

These studies help in developing quantitative safety models to predict cardiovascular risk, which can aid in dose selection and identifying patients who may experience significant blood pressure responses.

Home blood pressure monitoring (HBPM) is an effective self-monitoring tool for managing hypertension, leading to better blood pressure control and helping to identify conditions like white-coat hypertension, as supported by a growing body of evidence.

New HBPM technology features a longer inflatable cuff that improves accuracy by allowing for better placement on the arm, addressing the common issue of inaccurate readings in traditional monitors.

The program combining electronic home blood pressure monitoring and pharmacist-provided medication therapy management led to significant reductions in both systolic and diastolic blood pressure in 50 renal transplant recipients over one year, indicating improved blood pressure control (p < 0.05).

The involvement of a dedicated pharmacist in the renal transplant clinic helped identify and resolve medication-related issues in 46% of cases, enhancing medication adherence and overall patient care.
