Clinical Implementation of Self-Measured Blood Pressure Monitoring, 2015-2016

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.

A Case Series Study Assessing an Equity-Focused Implementation of Self-Monitoring Blood Pressure Programs Using Telehealth

CONTEXT

Self-monitoring blood pressure (SMBP) programs are an evidence-based hypertension management intervention facilitated through telehealth. SMBP programs can provide a continuum of care beyond a clinical setting by facilitating hypertension management at home; however, equitable access to SMBP is a concern.

OBJECTIVES

To evaluate the implementation of telehealth SMBP programs using an equity lens in 5 federally qualified health centers (FQHCs) in Massachusetts (MA).

DESIGN

A prospective case series study.

SETTING

Five FQHCs.

PARTICIPANTS

The MA Department of Public Health (MDPH) selected 5 FQHCs to implement SMBP programs using telehealth. FQHCs were selected if their patient population experiences inequities due to social determinants of health and has higher rates of cardiovascular disease. Each of the 5 FQHCs reported data on patients enrolled in their SMBP programs totaling 241 patients examined in this study.

INTERVENTION

SMBP programs implemented through telehealth.

MAIN OUTCOME MEASURE

Systolic blood pressure and diastolic blood pressure.

RESULTS

Approximately 53.5% of SMBP participants experienced a decrease in blood pressure. The average blood pressure decreased from 146/87 to 136/81 mm Hg. Among all patients across the 5 FQHCs, the average blood pressure decreased by 10.06/5.34 mm Hg (P < .001). Blood pressure improved in all racial, ethnic, and language subgroups.

CONCLUSIONS

Five MA FQHCs successfully implemented equitable telehealth SMBP programs. SMBP participants enrolled in the programs demonstrated notable improvements in their blood pressure at the conclusion of the program. A flexible, pragmatic study design that was adjusted to meet unique patient needs; engaging nonphysician team members, particularly community health workers; adapting health information technology; and partnerships with community-based organizations were critical facilitators to program success.

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.

Implementation Strategies to Improve Blood Pressure Control in the United States: A Scientific Statement From the American Heart Association and American Medical Association

Hypertension is one of the most important risk factors that contribute to incident cardiovascular events. A multitude of US and international hypertension guidelines, scientific statements, and policy statements have recommended evidence-based approaches for hypertension management and improved blood pressure (BP) control. These recommendations are based largely on high-quality observational and randomized controlled trial data. However, recent published data demonstrate troubling temporal trends with declining BP control in the United States after decades of steady improvements. Therefore, there is a widening disconnect between what hypertension experts recommend and actual BP control in practice. This scientific statement provides information on the implementation strategies to optimize hypertension management and to improve BP control among adults in the United States. Key approaches include antiracism efforts, accurate BP measurement and increased use of self-measured BP monitoring, team-based care, implementation of policies and programs to facilitate lifestyle change, standardized treatment protocols using team-based care, improvement of medication acceptance and adherence, continuous quality improvement, financial strategies, and large-scale dissemination and implementation. Closing the gap between scientific evidence, expert recommendations, and achieving BP control, particularly among disproportionately affected populations, is urgently needed to improve cardiovascular health.

Development of a Hypertension Electronic Phenotype for Chronic Disease Surveillance in Electronic Health Records: Key Analytic Decisions and Their Effects

INTRODUCTION

Modernizing chronic disease surveillance with electronic health record (EHR) data may provide better data to improve hypertension prevention and control, but no consensus exists for an EHR-based surveillance definition for hypertension. The Multi-State EHR-Based Network for Disease Surveillance (MENDS) pilot surveillance system was used to develop and test an electronic phenotype for hypertension.

METHODS

We used MENDS data from 1,671,279 patients in Louisiana to examine the effect of different analytic decisions on estimates of hypertension prevalence. Decisions included 1) whether to restrict surveillance to patients with recent blood pressure measurements, 2) varying the number and recency of encounters to define the population at risk of hypertension, 3) how to define hypertension (diagnosis codes, antihypertensive medication, blood pressure measurements, or combinations of these), and 4) how to handle multiple blood pressure measurements on the same day. Results were compared with independent estimates of hypertension prevalence in Louisiana from the Behavioral Risk Factor Surveillance System (BRFSS).

RESULTS

Applying varying criteria resulted in hypertension prevalence estimates ranging from 19.7% to 59.3%. A hypertension surveillance strategy that includes a population with at least 1 clinical encounter with measured blood pressure in the previous 2 years and identifies hypertension using all available data (≥1 diagnosis code, ≥1 antihypertensive medication, and ≥2 elevated blood pressure values ≥140/90 mm Hg on separate days) generated estimates in line with population-based survey data. This definition estimated the crude 2019 hypertension prevalence in the state of Louisiana as 43.4% (age-adjusted, 41.0%), comparable with the crude BRFSS estimate of 39.7% (age adjusted, 37.1%).

CONCLUSION

Applying different criteria to define hypertension using EHR data has a large effect on hypertension prevalence estimates. The proposed electronic phenotype generates hypertension prevalence estimates that align with independent estimates from BRFSS.

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

PURPOSE OF REVIEW

To evaluate how self-measured blood pressure (SMBP) monitoring interventions impact hypertension equity.

RECENT FINDINGS

While a growing number of studies have recruited participants from safety-net settings, racial/ethnic minority groups, rural areas, or lower socio-economic backgrounds, few have reported on clinical outcomes with many choosing to evaluate only patient-reported outcomes (e.g., satisfaction, engagement). The studies with clinical outcomes demonstrate that SMBP monitoring (a) can be successfully adopted by historically excluded patient populations and safety-net settings and (b) improves outcomes when paired with clinical support. There are few studies that explicitly evaluate how SMBP monitoring impacts hypertension disparities and among rural, low-income, and some racial/ethnic minority populations. Researchers need to design SMBP monitoring studies that include disparity reduction outcomes and recruit from broader populations that experience worse hypertension outcomes. In addition to assessing effectiveness, studies must also evaluate how to mitigate multi-level barriers to real-world implementation of SMBP monitoring programs.

Review of Long-Term Blood Pressure Control After Intracerebral Hemorrhage: Challenges and Opportunities

Blood pressure (BP) is the most important modifiable risk factor for intracerebral hemorrhage (ICH). Elevated BP is associated with an increased risk of ICH, worse outcome after ICH, and in survivors, higher risks of recurrent ICH, ischemic stroke, myocardial infarction, and cognitive impairment/dementia. As intensive BP control probably improves the chances of recovery from acute ICH, the early use of intravenous or oral medications to achieve a systolic BP goal of <140 mm Hg within the first few hours of presentation is reasonable for being applied in most patients. In the long-term, oral antihypertensive drugs should be titrated as soon as possible to achieve a goal BP <130/80 mm Hg and again in all ICH patients regardless of age, location, or presumed mechanism of ICH. The degree of sustained BP reduction, rather than the choice of BP-lowering agent(s), is the most important factor for optimizing risk reduction, with varying combinations of thiazide-type diuretics, long-acting calcium channel blockers, ACE (angiotensin-converting enzyme) inhibitors or angiotensin receptor blockers, being the mainstay of therapy. As most patients will require multiple BP-lowering agents, and physician inertia and poor adherence are major barriers to effective BP control, single-pill combination therapy should be considered as the choice of management where available. Increased population and clinician awareness, and innovations to solving patient, provider, and social factors, have much to offer for improving BP control after ICH and more broadly across high-risk groups. It is critical that all physicians, especially those managing ICH patients, emphasize the importance of BP control in their practice.

Clinical Practice Changes in Monitoring Hypertension Early in the COVID-19 Pandemic

BACKGROUND

Clinical practices can use telemedicine and other strategies (e.g., self-measured blood pressure [SMBP]) for remote monitoring of hypertension to promote control while decreasing risk of exposure to SARS-CoV-2, the virus that causes COVID-19.

METHODS

The DocStyles survey collected data from primary care providers (PCPs), obstetricians-gynecologists (OB/GYNs), and nurse practitioners/physician assistants (NP/PAs) in fall 2020 (n = 1,502). We investigated clinical practice changes for monitoring hypertension that were implemented early in the COVID-19 pandemic and examined differences by clinician and practice characteristics (P < 0.05).

RESULTS

Overall, 369 (24.6%) of clinicians reported their clinical practices made no changes in monitoring hypertension early in the pandemic, 884 (58.9%) advised patients to monitor blood pressure at home or a pharmacy, 699 (46.5%) implemented or increased use of telemedicine for blood pressure monitoring visits, and 545 (36.3%) reduced the frequency of office visits for blood pressure monitoring. Compared with NP/PAs, PCPs were more likely to advise SMBP monitoring (adjusted prevalence ratios [aPR] 1.28, 95% confidence intervals [CI] 1.11-1.47), implement or increase use of telemedicine (aPR 1.23, 95% CI 1.04-1.46), and reduce the frequency of office visits (aPR 1.37, 95% CI 1.11-1.70) for blood pressure monitoring, and less likely to report making no practice changes (aPR 0.63, 95% CI 0.51-0.77).

CONCLUSIONS

We noted variation in clinical practice changes by clinician type and practice characteristics. Clinical practices may need additional support and resources to fully maximize telemedicine and other strategies for remote monitoring of hypertension during pandemics and other emergencies that can disrupt routine health care.

Blood Pressure Control Among Non-Hispanic Black Adults Is Lower Than Non-Hispanic White Adults Despite Similar Treatment With Antihypertensive Medication: NHANES 2013-2018

BACKGROUND

Controlled blood pressure can prevent or reduce adverse health outcomes. Social and structural determinants may contribute to the disparity that despite equivalent proportions on antihypertensive medication, non-Hispanic Black (Black) adults have lower blood pressure control and more cardiovascular events than non-Hispanic White (White) adults.

METHODS

Data from 2013 to 2018 National Health and Nutrition Examination Survey were pooled to assess control among Black and White adults by antihypertensive medication use and selected characteristics using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) Blood Pressure Guideline definition (systolic blood pressure <130 mm Hg and diastolic blood pressure <80 mm Hg) among 4,739 adults.

RESULTS

Among those treated with antihypertensive medication, an estimated 34.9% of Black and 45.0% of White adults had controlled blood pressure. Control was lower for Black and White adults among most subgroups of age, sex, education, insurance status, usual source of care, and poverty-income ratio. Black adults had higher use of diuretics (28.5%-Black adults vs. 23.5%-White adults) and calcium channel blockers (24.2%-Black adults vs. 14.7%-White adults) compared with White adults. Control among Black adults was lower than White adults across all medication classes including diuretics (36.1%-Black adults vs. 47.3%-White adults), calcium channel blockers (30.2%-Black adults vs. 40.1%-White adults), and number of medication classes used.

CONCLUSIONS

Suboptimal blood pressure control rates and disparities warrant increased efforts to improve control, which could include addressing social and structural determinants along with emphasizing implementation of the 2017 ACC/AHA Blood Pressure Guideline into clinical practice.

How Do We Jump-Start Self-measured Blood Pressure Monitoring in the United States? Addressing Barriers Beyond the Published Literature

Hypertension is highly prevalent in the United States, and many persons with hypertension do not have controlled blood pressure. Self-measured blood pressure monitoring (SMBP), when combined with clinical support, is an evidence-based strategy for lowering blood pressure and improving control in persons with hypertension. For years, there has been support for widespread implementation of SMBP by national organizations and the federal government, and SMBP was highlighted as a primary intervention in the 2020 Surgeon General's Call to Action to Control Hypertension, yet optimal SMBP use remains low. There are well-known patient and clinician barriers to optimal SMBP documented in the literature. We explore additional high-level barriers that have been encountered, as broad policy and systems-level changes have been attempted, and offer potential solutions. Collective efforts could modernize data transfer and processing, improve broadband access, expand device coverage and increase affordability, integrate SMBP into routine care and reimbursement practices, and strengthen patient engagement, trust, and access.

Physician perceived barriers and facilitators for self-measured blood pressure monitoring- a qualitative study

INTRODUCTION

Improving hypertension management is a national priority that can decrease morbidity and mortality. Evidence-based hypertension management guidelines advocate self-measured BP (SMBP), but widespread implementation of SMBP is lacking. The purpose of this study was to describe the perspective of primary care physicians (PCPs) on SMBP to identify the barriers and facilitators for implementing SMBP.

METHODS

We collected data from PCPs from a large health system using semi-structured interviews based on the Theoretical Domains Framework (TDF). Responses were recorded, transcribed, and qualitatively analyzed into three overarching TDF domains based on the Behavior Change Wheel (BCW): 1) Motivation 2) Opportunity and 3) Capabilities. The sample size was based on theme saturation.

RESULTS

All 17 participating PCPs believed that SMBP is a useful, but underutilized tool. Although individual practices varied, most physicians felt that the increased data points from SMBP allowed for better hypertension management. Most felt that overcoming existing barriers would be difficult, but identified several facilitators: physician support of SMBP, the possibility of having other trained health professionals to assist with SMBP and patient education; improving patient engagement and empowerment with SMBP, and the interest of the health system in using technology to improve hypertension management.

CONCLUSION

PCPs believe that SMBP can improve hypertension management. There are numerous barriers and facilitators for implementing SMBP. Successful implementation in clinical practice will require implementation strategies targeted at increasing patient acceptability and reducing physician workload. This may need a radical change in the current methods of managing hypertension.

Are Community Health Center Patients Interested in Self-Measured Blood Pressure Monitoring (SMBP) - And Can They Do It?

Introduction

Self-measured blood pressure monitoring (SMBP) helps diagnose and manage hypertension from outside the clinic, which has implications for patient empowerment and outcomes, continuity of care, and resilience in care communities catering to vulnerable populations.

Methods

We instituted a protocol for SMBP among hypertensive patients at 9 community health centers in 3 states and administered questionnaires to patients before and after the protocol was instituted to assess knowledge and engagement with disease management, beliefs and attitudes towards, and experience doing SMBP. Questionnaires included 16 items designed to evaluate patient perceptions and beliefs about SMBP. These included a series of questions using a 5-point Likert scale, binary questions related to their perceived ability to comply with specific SMBP guidelines and open-ended questions to obtain descriptions of experiences with SMBP.

Results

The pre-questionnaire was completed by 478 patients and the post-questionnaire was completed by 372. Seventy-seven percent of respondents knew their ideal blood pressure and their engagement with blood pressure management increased significantly (p=0.0024) after completing the protocol. Additionally, 85% of respondents said that they had a positive experience doing SMBP. Open-ended responses revealed insight regarding why patients chose to do SMBP and factors patients appreciated about SMBP.

Discussion

When trained properly and supported, community health center patients are capable of and motivated to perform accurate SMBP. Our study provides evidence that health center patients can follow detailed SMBP protocols and monitor their own blood pressure from the safety of their homes, which is critical to their care continuum, particularly in days of a pandemic.

Knowledge, perception and practice of health professionals regarding blood pressure measurement methods: a scoping review

OBJECTIVE

Guideline-concordant performance of accurate blood pressure measurement (BPM), whether the modality is home (HBPM), ambulatory (ABPM), automated (AOBP) or office (OBPM), is dependent on proper technique. Knowledge, perception and practice of health professionals for BPM is crucial and has been partly studied, but a thorough review has never been reported. A scoping review of global studies was conducted to synthesize published data on this topic.

METHODS

An Arksey and O'Malley methodological framework was used. Keywords were identified and extraction was completed to April 2019 using CINAHL and MEDLINE. Studies were classified as positive for knowledge, perception and practice if the majority (>50%) of reported responses were favourable, and negative otherwise. If specific results were not reported, the author's conclusions were used to classified.

RESULTS

Seventy-two studies were identified: 25 HBPM, 14 ABPM, two AOBP, 40 OBPM. For knowledge, the percentage of negative studies were higher for HBPM (40%) and OBPM (68%) and lower for ABPM (14%) regarding BPM techniques. For perception, the number of negative studies were lower for HBPM (20%) and ABPM (7%) regarding usefulness of BPM methods in hypertension management. For practice, the number of negative studies were higher for HBPM (48%), ABPM (71%), OBPM (73%) and AOBP (50%) regarding implementation of hypertension guidelines.

CONCLUSION

The results of this scoping review demonstrate adequate perception of BPM but suboptimal knowledge and practice. Education is still needed to improve knowledge and practice. Future efforts should focus on improving what we know and what we do when measuring BP.

Self-Measured Blood Pressure Monitoring at Home: A Joint Policy Statement From the American Heart Association and American Medical Association

The diagnosis and management of hypertension, a common cardiovascular risk factor among the general population, have been based primarily on the measurement of blood pressure (BP) in the office. BP may differ considerably when measured in the office and when measured outside of the office setting, and higher out-of-office BP is associated with increased cardiovascular risk independent of office BP. Self-measured BP monitoring, the measurement of BP by an individual outside of the office at home, is a validated approach for out-of-office BP measurement. Several national and international hypertension guidelines endorse self-measured BP monitoring. Indications include the diagnosis of white-coat hypertension and masked hypertension and the identification of white-coat effect and masked uncontrolled hypertension. Other indications include confirming the diagnosis of resistant hypertension and detecting morning hypertension. Validated self-measured BP monitoring devices that use the oscillometric method are preferred, and a standardized BP measurement and monitoring protocol should be followed. Evidence from meta-analyses of randomized trials indicates that self-measured BP monitoring is associated with a reduction in BP and improved BP control, and the benefits of self-measured BP monitoring are greatest when done along with cointerventions. The addition of self-measured BP monitoring to office BP monitoring is cost-effective compared with office BP monitoring alone or usual care among individuals with high office BP. The use of self-measured BP monitoring is commonly reported by both individuals and providers. Therefore, self-measured BP monitoring has high potential for improving the diagnosis and management of hypertension in the United States. Randomized controlled trials examining the impact of self-measured BP monitoring on cardiovascular outcomes are needed. To adequately address barriers to the implementation of self-measured BP monitoring, financial investment is needed in the following areas: improving education and training of individuals and providers, building health information technology capacity, incorporating self-measured BP readings into clinical performance measures, supporting cointerventions, and enhancing reimbursement.

Home Blood Pressure Monitoring in Cases of Clinical Uncertainty to Differentiate Appropriate Inaction From Therapeutic Inertia

PURPOSE

Conventional clinic blood pressure (BP) measurements are routinely used for hypertension management and physician performance measures. We aimed to check home BP measurements after elevated conventional clinic BP measurements for which physicians did not intensify treatment, to differentiate therapeutic inertia from appropriate inaction.

METHODS

We conducted a pre and post study of home BP monitoring for patients with uncontrolled hypertension as determined by conventional clinic BP measurements for which physicians did not intensify hypertension management. Physicians were notified of average home BP 2-4 weeks after the initial clinic visit. Outcome measures were the proportion of patients with controlled hypertension using average home BP measurements, changes in hypertension management by physicians, changes in physicians' hypertension metrics, and factors associated with home-clinic BP differences.

RESULTS

Of 90 recruited patients who had elevated conventional clinic BP recordings, 65.6% had average home BP measurements that were <140/90 mm Hg. Physicians changed treatment plans for 61% of patients with average home BP readings of ≥140/90 mm Hg, whereas decisions to not change treatment for the remaining patients were based on contextual factors. Substituting average home BP for conventional clinic BP for 4% of patients from 2 physicians' hypertension registries improved the physicians' hypertension control rates by 3% to 5%. Greater body mass index and increased number of BP medications were associated with home BP measurement ≥140/90 mm Hg. Clinic BP levels did not estimate normal home BP levels.

CONCLUSIONS

Documented home BP in cases of clinical uncertainty helped differentiate therapeutic inertia from appropriate inaction and improved physicians' hypertension metrics.

Changes in community pharmacists' knowledge, attitudes, and practice regarding the management of hypertension before and after educational interventions

Objective: To clarify changes in community pharmacists' knowledge, attitudes, and practice regarding the management of hypertension before and after attending educational interventions based on their self-report on a questionnaire survey.Method: We conducted questionnaire surveys regarding the management of hypertension with a sample of community pharmacists before and after educational interventions.Results: The proportions of pharmacists who knew the 2014 Japanese Society of Hypertension Guidelines, guidelines for home blood pressure measurement, reference values for hypertension based on clinic-measured blood pressure, and reference values for hypertension based on home-measured blood pressure after the educational interventions (59.3%, 41.4%, 75.1%, and 70.8% respectively) were significantly higher relative to those recorded before interventions (31.6%, 13.7%, 47.7%, and 25.4% respectively).Conclusions: These findings suggest that in-house training might increase the knowledge of community pharmacists regarding hypertension management.
