Use of Self-Measured Blood Pressure Monitoring to Improve Hypertension Equity

Telemedicine Use and Hypertension Control in an Urban Community Health Center Cohort

BACKGROUND

Real-time or synchronous telemedicine can be a valuable adjunctive strategy for chronic disease management, but few studies have assessed its impact on hypertension control among safety-net populations.

OBJECTIVE

To evaluate whether telemedicine is associated with blood pressure (BP) control.

DESIGN

Retrospective cohort study. Mixed-effects logistic regression models clustered by the patient estimated associations between telemedicine and BP control after adjusting for patient factors and neighborhood context.

PARTICIPANTS

Patients seeking care at an urban, multisite community health center with hypertension and ≥1 BP measurement between 2020 and 2022 (3663 patient-year observations across 2086 unique patients).

MAIN MEASURES

The primary outcome was BP control defined as a binary variable. We used the Centers for Medicare & Medicaid Services' Controlling High Blood Pressure quality measure criteria of systolic blood pressure < 140 mmHg and diastolic blood pressure < 90 mmHg in the most recent recording in the measurement year.

KEY RESULTS

Among the 2086 patients with hypertension in our sample, there were 1257 (60.3%) Latinx and 425 (20.4%) Black patients. Over 90% lived in a neighborhood of high deprivation as categorized by the social deprivation index. Telemedicine visits, compared to none, were not associated with blood pressure control (1-2 telemedicine visits aOR, 1.05 [95% CI, 0.86-1.28]; ≥3 telemedicine visits aOR, 0.86 [95% CI, 0.68-1.09]). One in-person visit per year, compared to 2-3, was associated with lower odds of BP control (aOR, 0.72 [95% CI, 0.55-0.94]). Black patients, compared to Latinx patients, were less likely of having BP control (aOR, 0.64 [95% CI, 0.48-0.87]).

CONCLUSIONS

In this community health center cohort of patients with hypertension, telemedicine did not compromise blood pressure control. Persistent racial disparities in blood pressure control underscore the need for equity-centered strategies for hypertension management in safety-net primary care settings.

Federally qualified health center patients' experiences with remote patient monitoring as part of telehealth services for self-measured blood pressure monitoring

BACKGROUND

Remote patient monitoring (RPM) for hypertension management has become increasingly popular, demonstrating benefits for both clinics and patients. However, patient engagement in self-measured blood pressure (SMBP) monitoring remains low despite healthcare providers' efforts. This study aimed to assess adherence and acceptance of RPM for SMBP among Texas Federally Qualified Health Center patients.

METHODS

Participants enrolled in the SMBP monitoring program were recruited at three health centers. Data was collected from patient health records, and a questionnaire assessed hypertension self-management, technology acceptance, intentions, and attitudes toward SMBP. Thematic analysis was conducted for open-ended responses that followed each item, and multivariate linear regression assessed associations between psychosocial factors and SMBP use.

RESULTS

The sample (n = 47) was 64% female, 89% Hispanic/Latino, and 75% uninsured. Participants used RPM for SMBP an average of 46 days and 72 times within the first 120 days (~ 4 months). Age and behavioral intention were significantly positively associated with more days of SMBP use. Three themes emerged from open-ended data: perceived ease of learning and using mobile patient portal for SMBP, perceived benefits of using mobile patient portal for SMBP, and intentions to continue using the mobile patient portal for SMBP.

CONCLUSIONS

Participants found RPM for SMBP acceptable and easy to use. Use varied over time, with intention to use RPM for SMBP and older age linked to more days of use. RPM can enhance patient experience by providing additional information to the provider, prompting self-management discussions, and empowering patients to better control their BP.

Hypertension: A Continuing Public Healthcare Issue

Hypertension is a cardiovascular disease defined by an elevated systemic blood pressure. This devastating disease afflicts 30-40% of the adult population worldwide. The disease burden for hypertension is great, and it greatly increases the risk of cardiovascular morbidity and mortality. Unfortunately, there are a myriad of factors that result in an elevated blood pressure. These include genetic factors, a sedentary lifestyle, obesity, salt intake, aging, and stress. Although lifestyle modifications have had limited success, anti-hypertensive drugs have been moderately effective in lowering blood pressure. New approaches to control and treat hypertension include digital health tools and compounds that activate the angiotensin receptor type 2 (AT2), which can promote cardiovascular health. Nonetheless, research on hypertension and its management is vital for lessening the significant health and economic burden of this condition.

Long-term Monitoring of Blood Pressure in Older Adults: A Focus on Self-Measured Blood Pressure Monitoring

Hypertension is among the most common chronic conditions in older adults. Effective treatment exists, yet many older adults do not achieve recommended control of their blood pressure (BP). Self-measured blood pressure (SMBP) monitoring, in which patients check their BP at home, is one underutilized tool for improving hypertension control. Older adults may face unique challenges in using SMBP monitoring and therefore require unique solutions. An individualized approach to guiding older adults to use SMBP monitoring is preferred.

Patient Experience in a Remote Patient Monitoring Program for Hypertension: A Qualitative Study

BACKGROUND

Remote patient monitoring (RPM), which includes out-of-office blood pressure (BP) measurement, coupled with interventions including telehealth and team-based care, is recommended for hypertension (HTN) management. We aimed to assess participant experience with RPM for HTN (RPM-HTN) to understand barriers and facilitators to implementing RPM-HTN in a primary care population where health disparities and social inequities are prevalent.

METHODS

This is a qualitative implementation study of participants' experiences with an RPM-HTN program for primary care patients with uncontrolled HTN at an academic health system. We recruited participants with high and low levels of engagement (≥16 or <16 days of transmitted BP readings per month). Semi-structured interviews were conducted, and descriptive statistics and rapid qualitative analysis were used to identify factors affecting the implementation of RPM-HTN, specifically adoption, acceptability, appropriateness, and feasibility.

RESULTS

Multiple themes emerged from interviews with 14 participants. A doctor's recommendation and wanting help with BP management were facilitators for engagement, while work conflicts and forgetfulness were barriers to engagement. Participants enjoyed the format and content of nurse and clinical pharmacist phone calls and forming a relationship with the team; expressed improved understanding of HTN and BP management; and appreciated the convenience of remote monitoring.

CONCLUSIONS

Participants found RPM-HTN acceptable and appropriate, highlighting the team-based and out-of-office approach to care. This study provides actionable targets to overcome feasibility barriers to implementation. In order to increase engagement, RPM policies and procedures should take into account barriers including the quantity of required BP measurements and mechanisms of telehealth communication.

Implementing Self-Measured Blood Pressure Monitoring With Clinical Support: A Qualitative Study of Federally Qualified Health Centers

CONTEXT

Self-measured blood pressure monitoring (SMBP) with clinical support is effective at reducing blood pressure for people with hypertension. Although strengths and challenges around SMBP are well-documented, few studies describe the complexities of real-world implementation of SMBP with clinical support in the Federally Qualified Health Center (FQHC) setting.

PROGRAM

Between 2019 and 2023, the Ohio Department of Health funded the Ohio Association of Community Health Centers to manage a multiyear quality improvement (QI) project with 21 FQHCs. The project aimed to improve the identification and management of patients with hypertension, diabetes, and prediabetes. This study focuses on the activities implemented to provide SMBP support to patients with hypertension.

IMPLEMENTATION

FQHCs implemented clinical SMBP support using multiple roles, approaches, and resources. FQHCs established a process to identify patients eligible for SMBP support, provide blood pressure monitors, train patients on SMBP, track blood pressure readings, follow up with patients, and connect patients to resources.

EVALUATION

External evaluators interviewed 13 staff members within seven FQHCs from the QI project. Interviewed FQHCs were located across Ohio and represented urban, rural, suburban, and Appalachian areas. Clinical activities to support SMBP, facilitators, and barriers were identified with thematic analysis. The National Association of Community Health Centers SMBP Implementation Toolkit was used as a framework to assess SMBP activities. Facilitators included team-based care, health information technology capacity, funding for blood pressure monitors and staff time, leadership and staff support, and external support. Barriers included technology challenges, staffing shortages, low patient engagement, sustainability, and the COVID-19 pandemic.

DISCUSSION

This study demonstrates how FQHCs can use a variety of staff, processes, and resources to implement clinical SMBP support across a range of geographic regions. To facilitate this, FQHCs and patients may need more comprehensive insurance coverage of blood pressure monitors, reimbursement for staff time, and technology support.

Self-Measured Blood Pressure Monitoring During the COVID-19 Pandemic: Perspectives From Community Health Center Clinicians

ABSTRACT

The early period of the COVID-19 pandemic necessitated a rapid increase in out-of-office care. To capture the impact from COVID-19 on care for patients with hypertension, a questionnaire was disseminated to community health center clinicians. The extent, types, and causes of care delays and disruptions were assessed along with adaptations and innovations used to address them. Clinician attitudinal changes and perspectives on future hypertension care were also assessed. Of the 65 respondents, most (90.8%) reported their patients with hypertension experienced care delays or disruptions, including lack of follow-up, lack of blood pressure assessment, and missed medication refills or orders. To address care delays and disruptions for patients with hypertension, respondents indicated that their health center increased the use of telehealth or other technology, made home blood pressure devices available to patients, expanded outreach and care coordination, provided medication refills for longer periods of time, and used new care delivery options. The use of self-measured blood pressure monitoring (58.5%) and telehealth (43.1%) was identified as the top adaptations that should be sustained to increase access to and patient engagement with hypertension care; however, barriers to both remain. Policy and system level changes are needed to support value-based care models that include self-measured blood pressure and telehealth.

Linguistic Disparities in Diabetes Care Quality in California Community Health Centers Before and During the COVID-19 Pandemic

BACKGROUND

Disparities in diabetes care quality may have increased for patients with limited English language proficiency (LEP) compared to non-LEP patients during the COVID-19 pandemic. Changes in diabetes care quality for adult LEP and non-LEP patients of community health centers (CHCs) were examined from 2019 to 2020.

METHODS

Adults with Type 2 diabetes (n = 15 965) of 88 CHC sites in California and with 1+ visit/year in 2019 and 2020 from OCHIN electronic health record data were included. Multivariable regression models estimated the association of LEP status and changes in diabetes care quality from 2019 to 2020, controlling for patient sociodemographic and clinical characteristics. Interaction terms (LEP × 2020) were used to estimate differential over time changes in (1) blood pressure screening, (2) blood pressure control (<140/90 mm Hg), and (3) hemoglobin A1c control (HbA1c <8%) for LEP versus non-LEP patients.

RESULTS

LEP and non-LEP patients with diabetes had comparable blood pressure screening and control in 2019 and in 2020. LEP patients were less likely than non-LEP patients to have their HbA1c under control in 2019 (OR = 0.85, 95% CI = 0.77, 0.96, P = .006) and 2020 (OR = 0.83, 95% CI = 0.75, 0.92, P = .001). There were no differential changes in HbA1c control over time for LEP and non-LEP patients.

DISCUSSION

Although LEP patients were less likely than non-LEP patients to have their HbA1c under control, CHCs maintained quality of care equally for LEP and non-LEP patients with diabetes during the early pandemic period.

Eliminating hypertension disparities in U.S. non-Hispanic black adults: current and emerging interventions

PURPOSE OF REVIEW

Hypertension in non-Hispanic black (NHB) adults in the United States has an earlier onset, higher prevalence, and increased severity compared with other racial/ethnic populations. Uncontrolled hypertension is responsible for the increased burden of cardiovascular disease (CVD) morbidity and mortality and decreased longevity in NHB adults. Unfortunately, eliminating the persistent hypertension-associated disparities and the white/black mortality gap, worsened by the COVID-19 pandemic, has been challenging. Overcoming the social determinants of health (SDOH), implementing therapeutic lifestyle changes (TLC), and using intensive guideline-directed medical therapy are required. Moreover, novel approaches, including community-based interventions and self-measured blood pressure (SMBP) monitoring, may mitigate U.S. disparities in hypertension.

RECENT FINDINGS

In this review, we discuss recent data regarding the U.S. NHB adult disparate hypertension control and CVD morbidity and mortality. We note current approaches to address disparities, such as TLC, evidence-based pharmacotherapy, community-based interventions and SMBP. Finally, we explore future research and initiatives to seek hypertension-related health equity.

SUMMARY

In the final analysis, longstanding, unacceptable hypertension and CVD morbidity and mortality in U.S. NHB adults must be addressed. Appropriate TLC and evidence-based pharmacotherapy benefit all populations, especially NHB adults. Ultimately, novel community-based interventions and SMBP may help overcome the SDOH that cause hypertension disparities.

Innovative Remote Management Solutions for the Control of Hypertension

We stand at a critical juncture in the delivery of health care for hypertension. Blood pressure control rates have stagnated, and traditional health care is failing. Fortunately, hypertension is exceptionally well-suited to remote management, and innovative digital solutions are proliferating. Early strategies arose with the spread of digital medicine, long before the COVID-19 pandemic forced lasting changes to the way medicine is practiced. Highlighting one contemporary example, this review explores salient features of remote management hypertensive programs, including: an automated algorithm to guide clinical decisions, home (as opposed to office) blood pressure measurements, an interdisciplinary care team, and robust information technology and analytics. Dozens of emerging hypertension management solutions are contributing to a highly fragmented and competitive landscape. Beyond viability, profit and scalability are critical. We explore the challenges impeding large-scale acceptance of these programs and conclude with a hopeful look to the future when remote hypertension care will have dramatic impact on global cardiovascular health.

Randomized trial protocol for remote monitoring for equity in advancing the control of hypertension in safety net systems (REACH-SNS) study

BACKGROUND

Self-measured blood pressure monitoring (SMBP) is essential to effective management of hypertension. This study aims to evaluate effectiveness and implementation of SMBP that leverages: cellular-enabled home BP monitors without a need for Wi-Fi or Bluetooth; simple communication modalities such as text messaging to support patient engagement; and integration into existing team-based workflows in safety-net clinics.

METHODS

This study will be conducted with patients in San Francisco who are treated within a network of safety-net clinics. English and Spanish-speaking patients with diagnosed hypertension will be eligible for the trial if they have recent BP readings ≥140/90 mmHg and do not have co-morbid conditions that make home BP monitoring more complex to manage. This study will implement a three-arm randomized controlled trial to compare varying levels of implementation support: 1) cellular-enabled BP monitors (with minimal implementation support), 2) cellular-enabled BP monitors with protocol-based implementation support (text reminders for patients; aggregated BP summaries sent to primary care providers), and 3) cellular-enabled BP monitors and pharmacist-led support (pharmacist coaching and independent medication adjustments).

RESULTS

For the main analysis, we will use mixed effects linear regression to compare the change in primary outcome of systolic BP. Secondary outcomes include BP control (<140/90 mmHg), medication intensification, patient-reported outcomes, and implementation processes (i.e., engagement with the intervention).

DISCUSSION

This study will design and test a digital health intervention for use in marginalized populations treated within safety net settings, evaluating both effectiveness and implementation to advance more equitable health outcomes.

Randomized Controlled Trial of Home Telemonitoring of Blood Pressure with an Adapted Tensiometer with SMS Capability

Despite being a public health problem, less than a third of hypertensive patients manage to control blood pressure (BP). In this paper, we conducted a two-arm randomized controlled trial to investigate the efficacy of an SMS-based home BP telemonitoring system compared to usual care in patients with uncontrolled hypertension from a primary care center. This study was conducted between April and August 2018. Participants in the intervention arm used a custom-designed telemonitoring device for two weeks and were followed up for two additional weeks; controls were followed for 4 weeks. The main objective of this study is to evaluate the impact on blood pressure of a telemonitoring system using a blood pressure monitor adapted to send data via SMS to health providers in primary care centers for 4 weeks. In this trial, 38 patients were included in the analysis (18 in each arm), 68% were women, and the mean age was 68.1 [SD: 10.8 years], with no differences between arms. Among the results we found was that There was no significant difference in the change in systolic BP values between the control and intervention arm (-7.2 [14.9] mmHg vs. -16.3 [16.7] mmHg; p = 0.09). However, we found a significant difference in the change of diastolic BP (-1.2 [6.4] mmHg vs. -7.2 [9.8] mmHg; for the control and intervention arms, respectively p = 0.03). With all this, we conclude that an SMS-based home BP telemonitoring system is effective in reducing diastolic BP by working in conjunction with primary care centers. Our findings represent one of the first interventions of this type in our environment, being an important alternative for the control of high blood pressure.

Unsung heroes in health education and promotion: How Community Health Workers contribute to hypertension management

Rural communities are noted as having poor health outcomes. Rural areas experience barriers to care primarily due to a lack of resources, including education, health insurance, transportation, and social support. Additionally, poor health outcomes are a consequence of poor health literacy skills. Community Health Workers (CHWs) are utilized as a resource to combat these issues. This study focused on a CHW led Self-Management Blood Pressure (SMBP) program offered through the University of Texas at Tyler Health Science Center. The goal of the program was to improve management of hypertension through awareness, education, navigation, advocacy, and resource assistance. The SMBP program included structured workshops and regular follow-up with participants including connections to community resources and social support. CHWs worked closely with physicians providing bi-directional feedback on referrals and engagement of communities through outreach events. Furthermore, CHWs aided to bridge cultural or linguistic gaps between service providers and community members. Data is provided indicating this CHW-led intervention played a significant role in improving hypertension through education of how to make lifestyle changes that impact overall health and quality of life. Participants gained knowledge encouraging them to create lifelong healthy habits, coping skills, stress management, self-care, and accountability. Through this innovative approach, participants thrived in the supportive and encouraging environment led by CHWs as well as improved their blood pressure management.
