Implementing Home Blood Pressure Monitoring into Clinical Practice

Hypertension management in chronic kidney disease: A guide for NPs

ABSTRACT

This article offers a guide for NPs for managing hypertension (HTN) in adults in the setting of chronic kidney disease (CKD). It outlines evidence-based strategies, including lifestyle modifications, pharmacologic interventions, and patient education measures, that can be used in patients with CKD to optimize BP control. Special considerations, such as comorbid mental health conditions and individualized treatment plans, are also addressed. NPs play a pivotal role in improving outcomes by fostering patient engagement and adherence. By embracing this holistic approach, NPs are poised to enhance the quality of care and well-being of patients with CKD and HTN.

Implementation barriers and facilitators of remote monitoring, remote consultation and digital care platforms through the eyes of healthcare professionals: a review of reviews

OBJECTIVES

Digital transformation in healthcare is a necessity considering the steady increase in healthcare costs, the growing ageing population and rising number of people living with chronic diseases. The implementation of digital health technologies in patient care is a potential solution to these issues, however, some challenges remain. In order to navigate such complexities, the perceptions of healthcare professionals (HCPs) must be considered. The objective of this umbrella review is to identify key barriers and facilitators involved in digital health technology implementation, from the perspective of HCPs.

DESIGN

Systematic umbrella review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

DATA SOURCES

Embase.com, PubMed and Web of Science Core Collection were searched for existing reviews dated up to 17 June 2022. Search terms included digital health technology, combined with terms related to implementation, and variations in terms encompassing HCP, such as physician, doctor and the medical discipline.

ELIGIBILITY CRITERIA

Quantitative and qualitative reviews evaluating digital technologies that included patient interaction were considered eligible. Three reviewers independently synthesised and assessed eligible reviews and conducted a critical appraisal.

DATA EXTRACTION AND SYNTHESIS

Regarding the data collection, two reviewers independently synthesised and interpreted data on barriers and facilitators.

RESULTS

Thirty-three reviews met the inclusion criteria. Barriers and facilitators were categorised into four levels: (1) the organisation, (2) the HCP, (3) the patient and (4) technical aspects. The main barriers and facilitators identified were (lack of) training (n=22/33), (un)familiarity with technology (n=17/33), (loss of) communication (n=13/33) and security and confidentiality issues (n=17/33). Barriers of key importance included increased workload (n=16/33), the technology undermining aspects of professional identity (n=11/33), HCP uncertainty about patients' aptitude with the technology (n=9/33), and technical issues (n=12/33).

CONCLUSIONS

The implementation strategy should address the key barriers highlighted by HCPs, for instance, by providing adequate training to familiarise HCPs with the technology, adapting the technology to the patient preferences and addressing technical issues. Barriers on both HCP and patient levels can be overcome by investigating the needs of the end-users. As we shift from traditional face-to-face care models towards new modes of care delivery, further research is needed to better understand the role of digital technology in the HCP-patient relationship.

Facilitators and barriers to home blood pressure monitoring among pregnant women in Ghana: a mixed-methods analysis of patient perspectives

BACKGROUND

The benefit of home blood pressure monitoring during pregnancy and in low-resource settings is incompletely understood. The objective of this study was to explore the experiences, barriers, and facilitators of home blood pressure monitoring among pregnant women in Ghana.

METHODS

This concurrent triangulation mixed-methods study was conducted at an urban tertiary hospital in Ghana. Participants were recruited from adult pregnant women presenting for routine antenatal care. Upon enrollment, participants' demographics and history were collected. At the next study visit, participants received audiovisual and hands-on training on using an automatic blood pressure monitor; they then monitored and logged their blood pressure daily at home for 2-4 weeks. At the final study visit, verbally administered surveys and semi-structured interviews assessed participant's experiences. Quantitative data were analyzed using R version 4.2.2, and frequencies and descriptive statistics were calculated. Qualitative data were imported into DeDoose 9.0.78 for thematic analysis.

RESULTS

Of 235 enrolled participants, 194 completed surveys; of those, 33 completed in-depth interviews. Participants' mean age was 31.6 (SD 5.3) years, 32.1% had not previously given birth, and 31.1% had less than a senior high school education. On a 4-point Likert scale, the majority reported they "definitely" were able to remember (n = 134, 69.1%), could find the time (n = 124, 63.9%), had the energy (n = 157, 80.9%), could use the blood pressure monitor without problems (n = 155, 79.9%), and had family approval (n = 182, 96.3%) while engaging in home blood pressure monitoring. 95.88% (n = 186) believed that pregnant women in Ghana should monitor their blood pressure at home. Qualitative thematic analysis demonstrated that most participants liked home blood pressure monitoring because of increased knowledge of their health during pregnancy. While most participants found measuring their blood pressure at home doable, many faced challenges. Participants' experiences with five key factors influenced how easy or difficult their experience was: 1) Time, stress, and daily responsibilities; 2) Perceived importance of BP in pregnancy; 3) Role of family; 4) Capability of performing monitoring; 5) Convenience of monitoring.

CONCLUSIONS

Among pregnant women in urban Ghana, home blood pressure monitoring was perceived as positive, important, and doable; however, challenges must be addressed.

Home Blood Pressure Monitoring and Its Association With Blood Pressure Control Among Hypertensive Patients With High Cardiovascular Risk in China

Objective

Home blood pressure monitoring (HBPM) is viewed as a facilitating factor in the initial diagnosis and long-term management of treated hypertension. However, evidence remains scarce about the effectiveness of HBPM use in the real world. This study aimed to examine the associations of HBPM use with blood pressure (BP) control and medication adherence.

Methods

This prospective cohort study included hypertensive patients with high cardiovascular risk who were aged ≥50 years. At baseline, information about types of BP monitor, frequency of HBPM, perception of anti-hypertensive treatment, and measured office BP were collected. During the 1-year follow-up (visits at 1, 2, 3, 6, and 12 months), information on medication adherence was collected at each visit. The 2 major outcomes were BP control at baseline and medication adherence during the 1-year follow-up. A log-binomial regression model was used to examine the association between frequency of HBPM and outcomes, stratified by the perceptions of anti-hypertensive treatment.

Results

A total of 5,363 hypertensive patients were included in the analysis. The age was (64.6 ± 7.2) years, and 41.2% (2,208) were female. Of the total patients, 85.9% (4,606) had a home BP monitor and 47.8% (2,564) had an incorrect perception of anti-hypertensive treatment. Overall, 24.2% (1,299) of patients monitored their BP daily, 37.6% (2,015) weekly, 17.3% (926) monthly, and 20.9% (1,123) less than monthly. At baseline, the systolic BP and diastolic BP were (146.6 ± 10.8) mmHg and (81.9 ± 10.6) mmHg, respectively, and 28.5% (1,527) of patients had their BP controlled. Regardless of whether the patients had correct or incorrect perceptions of anti-hypertensive treatment, there is no significant association between HBPM frequency and BP control at baseline. During the 1-year follow-up, 23.9% (1,280) of patients had non-adherence to medications at least once. In patients with an incorrect perception of anti-hypertensive treatment, those monitoring BP most frequently (daily) had the highest non-adherence rate (29.9%, 175/585). Compared with those monitoring their BP less than monthly, patients who monitored their BP daily were more likely not to adhere to anti-hypertensive medications (adjusted relative risk = 1.38, 95% confidence interval: 1.11-1.72, P = 0.004).

Conclusions

HBPM performance among hypertensive patients in China is, in general, sub-optimal. No association was observed between using HBPM alone and hypertension control, indicating that the effects of HBPM could be conditional. Patients' misconceptions about anti-hypertensive treatment may impair the role of BP monitoring in achieving medication adherence. Fully incorporating the correct perception of hypertension into the management of hypertensive patients is needed.

The Standardization of Home Blood Pressure Monitoring in Primary Care: A Quality Improvement Project

Current guidelines recommend the use of home blood pressure monitoring (HBPM) to screen for and manage hypertension. In this study, a quality improvement project was designed to standardize the use of HBPM in a primary care setting and demonstrate improved blood pressure outcomes. Initial systolic and diastolic values were compared to averages from patient logs. Patient and provider feedback was collected. Only 40% of patients enrolled presented to follow-up with actionable HBPM data. Patients encountered logistical challenges in obtaining and presenting HBPM data. Interprofessional collaboration and improved information technology systems would improve outcomes. This will require increased policy and insurer support to make this possible in small settings.

Automated Messaging Program to Facilitate Systematic Home Blood Pressure Monitoring: Qualitative Analysis of Provider Interviews

BACKGROUND

Hypertension is a leading cause of cardiovascular and kidney disease in the United States, yet blood pressure (BP) control at a population level is poor and worsening. Systematic home BP monitoring (HBPM) programs can lower BP, but programs supporting HBPM are not routinely used. The MyBP program deploys automated bidirectional text messaging for HBPM and disease self-management support.

OBJECTIVE

We aim to produce a qualitative analysis of input from providers and staff regarding implementation of an innovative HBPM program in primary care practices.

METHODS

Semistructured interviews (average length 31 minutes) were conducted with physicians (n=11), nurses, and medical assistants (n=6) from primary care settings. The interview assessed multiple constructs in the Consolidated Framework for Implementation Research domains of intervention characteristics, outer setting, inner setting, and characteristics of individuals. Interviews were transcribed verbatim and analyzed using inductive coding to organize meaningful excerpts and identify salient themes, followed by mapping to the updated Consolidated Framework for Implementation Research constructs.

RESULTS

Health care providers reported that MyBP has good ease of use and was likely to engage patients in managing their high BP. They also felt that it would directly support systematic BP monitoring and habit formation in the convenience of the patient's home. This could increase health literacy and generate concrete feedback to raise the day-to-day salience of BP control. Providers expressed concern that the cost of BP devices remains an encumbrance. Some patients were felt to have overriding social or emotional barriers, or lack the needed technical skills to interact with the program, use good measurement technique, and input readings accurately. With respect to effects on their medical practice, providers felt MyBP would improve the accuracy and frequency of HBPM data, and thereby improve diagnosis and treatment management. The program may positively affect the patient-provider relationship by increasing rapport and bidirectional accountability. Providers appreciated receiving aggregated HBPM data to increase their own efficiency but also expressed concern about timely routing of incoming HBPM reports, lack of true integration with the electronic health record, and the need for a dedicated and trained staff member.

CONCLUSIONS

In this qualitative analysis, health care providers perceived strong relative advantages of using MyBP to support patients. The identified barriers suggest the need for corrective implementation strategies to support providers in adopting the program into routine primary care practice, such as integration into the workflow and provider education.

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.

Prognostic value of home blood pressure monitoring in patients under antihypertensive treatment

The prognostic value of home blood pressure monitoring (HBPM) has been investigated in several studies in the general population, demonstrating its independent association with cardiovascular events. However, in the case of treated hypertensive subjects, evidence is controversial. Our purpose was to evaluate the prognostic value of HBPM in this population. Medicated hypertensive patients who performed a 4-day HBPM (Omron® HEM-705CP-II) between 2008 and 2015 were followed up for a median of 5.9 years, registering the occurrence of a composite primary outcome of fatal and non-fatal cardiovascular events. Cox regression models were used to analyze the prognostic value of HBPM, considering 4-day measurements, discarding the first day, and analyzing morning, afternoon and evening periods separately. We included 1582 patients in the analysis (33.4% men, median age 70.8 years, on an average of 2.1 antihypertensive drugs). During follow-up, 273 events occurred. HBPM was significantly associated with cardiovascular events in all five scenarios in the unadjusted models. When adjusting for office BP and other cardiovascular risk factors, the association remained marginally significant for the 4-day period, discarding first-day measurements HBPM (HR 1.04 [95% CI 1-1.1] and 1.04 [95% CI 1-1.1], respectively) and statistically significant for all separate periods of measurement: HR 1.32 (95% CI 1.01-1.72); 1.33 (95% CI 1.02-1.72); and 1.30 (95% CI 1.01-1.67), for morning, afternoon and evening, respectively. When analyzing separately fatal and non-fatal events, statistical significance was held for the former only. In conclusion, HBPM is an independent predictor of cardiovascular events in hypertensives under treatment.

Validation of the AViTA BPM636 upper arm blood pressure monitor in adults and pregnant women according to the ANSI/AAMI/ISO 81060-2:2013

OBJECTIVE

To evaluate the accuracy of the AViTA oscillometric upper arm home blood pressure (BP) monitor in adult and pregnant populations according to the American National Standards Institute/Association for the Advancement of Medical Instrumentation/ International Organization for Standardization (ANSI/AAMI/ISO) Universal Standard (ISO 81060-2:2013).

METHODS

BP measurements on the upper arm were performed on 85 adult subjects and 46 pregnant subjects. The AViTA BPM636 and a standard mercury reference sphygmomanometer were applied and followed the same arm sequential BP measurement method. The universal cuff of the test device was used for arm circumference of 22-42 cm.

RESULTS

For validation criterion 1, the mean ± SD of the differences between the test device and reference BP readings was 1.1 ± 5.49/2.9 ± 5.17 mmHg (systolic/diastolic) for adults; and -2.2 ± 5.93/1.5 ± 4.92 mmHg (systolic/diastolic) for pregnant women. For criterion 2, the SD of the averaged BP differences between the test device and reference BP per adult subject was 4.45/4.20 mmHg (systolic/diastolic) and per pregnant women was 4.66/3.96.

CONCLUSION

The AViTA BPM636 had passed the criteria of the ANSI/AAMI/ISO 81060-2:2013 protocol and can be recommended for home BP measurements in adults and pregnant populations.

An Opportunity to Better Address Hypertension in Women: Self-Measured Blood Pressure Monitoring

More than 56 million women in the United States have hypertension, including almost one in five women of reproductive age. The prevalence of hypertensive disorders of pregnancy is on the rise, putting more women at risk for adverse pregnancy-related outcomes and atherosclerotic cardiovascular disease later in life. Hypertension can be better detected and controlled in women throughout their life course by supporting self-measured blood pressure monitoring. In this study, we present some potential strategies for strengthening our nation's ability to address hypertension in women focusing on pregnancy-related considerations for self-measured blood pressure monitoring.

A multicenter prospective study of home blood pressure measurement (HBPM) during pregnancy in Japanese women

In the near future, hypertensive disorders of pregnancy (HDP) have been diagnosed by home blood pressure monitoring (HBPM) instead of clinic BP monitoring. A multicenter study of HBPM was performed in pregnant Japanese women in the non-high risk group for HDP. Participants were women (n = 218), uncomplicated pregnancy who self-measured and recorded their HBP daily. Twelve women developed HDP. HBP was appropriate (100 mmHg in systole and 63 mmHg in diastole), bottoming out at 17 to 21 weeks of gestation. It increased after 24 weeks of gestation and returned to non-pregnant levels by 4 weeks of postpartum. The upper limit of normal HBP was defined as the mean value +3 SD for systolic and mean +2 SD for diastolic with reference to the criteria for non-pregnant women. Using the polynomial equation, the hypertensive cut-off of systolic HBP was 125 mmHg at 15 weeks and 132 mmHg at 30 weeks of gestation, while it for diastolic HBP was 79 mmHg at 15 weeks and 81 mmHg at 30 weeks of gestation. Systolic HBP in women who developed HDP was higher after 24 weeks of gestation, and diastolic HBP was higher during most of the pregnancy compared to normal pregnancy. When the variability of individual HBP in women developed HDP compared to normal pregnant women was examined using the coefficient of variation (CV), the CV was lower in HDP before the onset of HDP. HBPM can be used not only for HDP determination, but also for early detection of HDP.

Impact of Home Telemonitoring and Management Support on Blood Pressure Control in Nondialysis CKD: A Systematic Review and Meta-Analysis

Background:

Hypertension is a major cause of cardiovascular disease, chronic kidney disease (CKD), and death. Several studies have demonstrated the efficacy of home blood pressure telemonitoring (HBPT) for blood pressure (BP) control and outcomes, but the effects of this intervention remain unclear in patients with CKD.

Objective:

To determine the impact of HBPT on cardiovascular–related and kidney disease–related outcomes in patients with CKD.

Design:

Systematic review and meta-analysis.

Setting:

All studies that met our criteria regardless of country of origin.

Participants:

Patients with chronic kidney disease included in studies using HBPT for BP assessment and control.

Measurements:

Descriptive and quantitative analysis of our primary and secondary outcomes.

Methods:

We searched MEDLINE, Embase, CINAHL Plus, PsycINFO, Cochrane CENTRAL, Web of Science, and gray literature from inception for observational and randomized controlled studies in nondialysis (ND) CKD using HBPT for BP control. We selected studies that used HBPT as intervention (with or without a control arm) for BP control in ND-CKD populations. The primary outcome was change in mean systolic BP (SBP) and mean diastolic BP (DBP).

Results:

We selected 7 studies from 1669 articles that were initially identified. Overall, pooled estimates in the mean difference (MD) for SBP and DBP were −8.8 mm Hg; 95% confidence interval (CI): −16.2 to −1.4; P = .02 and −2.4 mm Hg; 95% CI: −3.8 to −1.0; P < .001, respectively. For studies comparing intervention with usual care (UC), pooled estimate in MD for SBP was −8.0 mm Hg (P = .02) with no significant reduction for DBP (−2.6 mm Hg; P = .18). In studies without a UC arm, both SBP and DBP were not significantly reduced (P > .05). The pooled estimate in MD for estimated glomerular filtration rate showed a significant improvement (5.4 mL/min/1.73 m²; P < .001).

Limitations:

Heterogeneity and few available studies for inclusion limited our ability to identify a robust link between HBPT use and BP and kidney function improvement.

Conclusion:

Home blood pressure telemonitoring is associated with mild lowering of BP and moderately improved kidney function in patients with CKD. However, larger studies with improved designs and prolonged interventions are still needed to assess the effects of HBPT on patients’ outcomes.

Predicting Out-of-Office Blood Pressure in a Diverse US Population

BACKGROUND

The PRedicting Out-of-OFfice Blood Pressure (PROOF-BP) algorithm accurately predicted out-of-office blood pressure (BP) among adults with suspected high BP in the United Kingdom and Canada. We tested the accuracy of PROOF-BP in a diverse US population and evaluated a newly developed US-specific algorithm (PROOF-BP-US).

METHODS

Adults with ≥2 office BP readings and ≥10 awake BP readings on 24-hour ambulatory BP monitoring from 4 pooled US studies were included. We compared mean awake BP with predicted out-of-office BP using PROOF-BP and PROOF-BP-US. Our primary outcomes were hypertensive out-of-office systolic BP (SBP) ≥130 mm Hg and diastolic BP (DBP) ≥80 mm Hg.

RESULTS

We included 3,058 adults, mean (SD) age was 52.0 (11.9) years, 38% were male, and 54% were Black. The area under the receiver-operator characteristic (AUROC) curve (95% confidence interval) for hypertensive out-of-office SBP was 0.81 (0.79-0.82) and DBP was 0.76 (0.74-0.78) for PROOF-BP. For PROOF-BP-US, the AUROC curve for hypertensive out-of-office SBP was 0.82 (0.81-0.83) and for DBP was 0.81 (0.79-0.83). The optimal predicted out-of-office BP ranges for out-of-office BP measurement referral were 120-134/75-84 mm Hg for PROOF-BP and 125-134/75-84 mm Hg for PROOF-BP-US. The 2017 American College of Cardiology/American Heart Association BP guideline (referral range 130-159/80-99 mm Hg) would refer 93.1% of adults not taking antihypertensive medications with office BP ≥130/80 mm Hg in the National Health and Nutrition Examination Survey for out-of-office BP measurement, compared with 53.1% using PROOF-BP and 46.8% using PROOF-BP-US.

CONCLUSIONS

PROOF-BP and PROOF-BP-US accurately predicted out-of-office hypertension in a diverse sample of US adults.

A count-based decision method for target blood pressure achievement in home blood pressure monitoring data interpretation for clinical practices

Home blood pressure (HBP) is useful to decide whether blood pressure (BP) is controlled. However, applying HBP to daily clinical practices is still challenging without easy access to the average HBP. Therefore, we developed a simple method to make a quick decision regarding the controlledness of HBP through high BP counts. We simulated 100 cases of HBP series for each combination of 3 numbers of BP readings (K = 16, 20, 24) and 4 levels of the standard deviations (SDs = 5, 10, 15, 20). A high BP was defined as an individual BP ≥ 135/85 mmHg, and an uncontrolled HBP was defined as a mean HBP ≥ 135/85 mmHg. Validation for the decision method was conducted using actual HBP data. The C-statistics and the accuracy of the high BP counts for the uncontrolled HBP were generally high (> 0.85) for all combinations of Ks and SDs and decreased as SDs increased but remained steady as Ks increased. In validation, the C-statistic of the high BP count-to-total BP reading (C/T) ratio was 0.985, and the C/T ratio ≥ 0.5 showed a sensitivity of 0.957, a specificity of 0.907, and an accuracy of 0.927. The count-based decision method can provide an accurate quick assessment of the controlledness of HBP.

Risk Prediction Model for Uncontrolled Hypertension in Chinese Community

Background

Uncontrolled hypertension rate was still high across China. This study develops and validates an index to help quantify the combination of socio-behavioral aspects to screen high-risk patients in uncontrolled hypertension in Chinese primary care.

Methods

A cross-sectional study included 1,039 of patients with hypertension in the Chinese community. We assessed independent risk factors of uncontrolled blood pressure (defined as having a blood pressure ≥140/90 mmHg, even with antihypertensive therapy) and develop a risk prediction model.

Results

Among the 1,039 patients (53.9% male, the average age was 61 ± 13 years), 452 (43.5%) were uncontrolled hypertensive. Multivariable analysis showed that worker (odds ratio, OR: 1.98, 95% CI: 1.46–2.69), no health insurance (OR: 3.47, 95% CI: 2.08–5.80), non-marital status (OR: 2.01, 95% CI: 1.35–3.27), and other socio-behavioral aspects were independent risk factors of uncontrolled hypertension, which were included the final prediction model (C-static: 0.781). With internal validation by the bootstrap method, the risk score showed good discriminating ability and predicting ability for the incidence of uncontrolled hypertension (C-static: 0.771).

Conclusions

This study showed that nearly half of the patients suffered from uncontrolled hypertension in the Chinese community. We established a prediction model with good predictability to help quantify the combination of socio-behavioral aspects and screen high-risk patients with uncontrolled hypertension.

White Coat Uncontrolled Hypertension in Teleconsultation: A New and Frequent Entity

Introduction

Cardiovascular risk seems not to be greater in patients with white coat uncontrolled hypertension (WUCH) than in patients with sustained blood pressure (BP) control. Therefore, its detection is important to avoid overtreatment. The COVID-19 pandemic determined a massive migration of hypertension consultations from the face-to-face modality to teleconsultations, and it is unknown whether WUCH exists in this context.

Aim

We aimed to evaluate the prevalence of WUCH through home BP monitoring (HBPM) in treated hypertensive patients evaluated by teleconsultation.

Methods

We included treated hypertensive patients that owned a digital BP monitor. During teleconsultation, patients were asked to perform two BP measurements and then a 7-day HBPM, using the same device. Patients were classified as having WUCH if BP was ≥ 140 and/or 90 mmHg in teleconsultation and < 135/85 mmHg on HBPM. The prevalence of WUCH and its 95% confidence interval were estimated. One-way ANOVA, the Chi-square test or Fisher’s exact test were used to compare the characteristics of these patients with the other groups.

Results

We included 341 patients (45.2% male, mean age 62.3 years). The prevalence of WUCH was 33.1% (95% CI 28.3–38.3%). Significant differences were found in terms of age, the number of antihypertensive drugs and the use of calcium channel blockers, all lower in the WUCH group as compared with the groups with elevated BP on HBPM.

Conclusion

WUCH exists in teleconsultation and is very frequent. It can be easily detected though HBPM, thus avoiding overmedication, and its potential impact on side-effects and health costs.

Self-Monitoring of Urinary Hormones in Combination with Telemedicine - a Timely Review and Opinion Piece in Medically Assisted Reproduction

Cycle monitoring via ultrasound and serum-based hormonal assays during medically assisted reproduction (MAR) can provide information on ovarian response and assist in optimizing treatment strategies in addition to reducing complications such as ovarian hyperstimulation syndrome (OHSS). Two surveys conducted in 2019 and 2020, including overall 24 fertility specialists from Europe, Asia and Latin America, confirmed that the majority of fertility practitioners routinely conduct hormone monitoring during MAR. However, blood tests may cause inconvenience to patients. The reported drawbacks of blood tests identified by the survey included the validity of results from different service providers, long waiting times and discomfort to patients due to travelling to clinics for tests and repeated venepunctures. Historically, urine-based assays were used by fertility specialists in clinics but were subsequently replaced by more practical and automated serum-based assays. A remote urine-based hormonal assay could be an alternative to current serum-based testing at clinics, reducing the inconvenience of blood tests and the frequency of appointments, waiting times and patient burden. Here we provide an overview of the current standard of care for cycle monitoring and review the literature to assess the correlation between urine-based hormonal assays and serum-based hormonal assays during MAR. In addition, in this review, we discuss the evidence supporting the introduction of remote urine-based hormonal monitoring as part of a novel digital health solution that includes remote ultrasound and tele-counselling to link clinics and patients at home.

Prognostic value of masked uncontrolled apparent resistant hypertension detected through home blood pressure monitoring

OBJECTIVE

Resistant hypertension carries a poor prognosis and current guidelines recommend the exclusion of the white-coat phenomenon for proper diagnosis. However, guidelines do not focus on patients treated with at least three drugs whose blood pressure (BP) is controlled at the office but elevated out of it. We aimed at determining whether this masked uncontrolled apparent resistant hypertension (MUCRH) detected through home blood pressure monitoring (HBPM) has prognostic value for fatal and nonfatal events in these hypertensive patients.

METHODS

Hypertensive patients treated with at least three drugs who performed a baseline HBPM between 2008 and 2015 were followed to register the occurrence of total mortality, cardiovascular mortality, and fatal and nonfatal cardiac and cerebrovascular events. MUCRH was defined as office blood pressure less than 140/90 mmHg and home BP at least 135 and/or 85 mmHg. Multivariable Cox proportional hazard models were adjusted to determine the independent prognostic value of MUCRH for the events of interest.

RESULTS

We included 470 patients, 35.5% male, mean age 71.9 years, and treated with 3.3 antihypertensive drugs on average. Among study population, 15.5% had MUCRH (33.3% when considering only patients with adequate BP control at the office). Median follow-up was 6.7 years. In multivariable models, MUCRH was an independent predictor for cardiovascular mortality and cerebrovascular events: hazard ratio 4.9 (95% CI 1.2-19.9, P = 0.03) and 5.1 (95% CI 1.5-16.9, P = 0.01), respectively.

CONCLUSION

MUCRH is not rare and is independently associated with cardiovascular morbidity and mortality. The systematic monitoring of intensively treated individuals through HBPM would be useful for the detection of patients at increased risk of events.

Adherence to Telemonitoring Therapy for Medicaid Patients With Hypertension: Case Study

Background

Almost 50% of the adults in the United States have hypertension. Although clinical trials indicate that home blood pressure monitoring can be effective in managing hypertension, the reported results might not materialize in practice because of patient adherence problems.

Objective

The aims of this study are to characterize the adherence of Medicaid patients with hypertension to daily telemonitoring, identify the impacts of adherence reminder calls, and investigate associations with blood pressure control.

Methods

This study targeted Medicaid patients with hypertension from the state of Texas. A total of 180 days of blood pressure and pulse data in 2016-2018 from a telemonitoring company were analyzed for mean transmission rate and mean blood pressure change. The first 30 days of data were excluded because of startup effects. The protocols required the patients to transmit readings by a specified time daily. Patients not transmitting their readings received an adherence reminder call to troubleshoot problems and encourage transmission. The patients were classified into adherent and nonadherent cohorts; adherent patients were those who transmitted data on at least 80% of the days.

Results

The mean patient age was 73.2 (SD 11.7) years. Of the 823 patients, 536 (65.1%) were women, and 660 (80.2%) were urban residents. The adherent cohort (475/823, 57.7%) had mean transmission rates of 74.9% before the adherence reminder call and 91.3% after the call, whereas the nonadherent cohort (348/823, 42.3%) had mean transmission rates of 39% and 58% before and after the call, respectively. From month 1 to month 5, the transmission rates dropped by 1.9% and 10.2% for the adherent and nonadherent cohorts, respectively. The systolic and diastolic blood pressure values improved by an average of 2.2 and 0.7 mm Hg (P<.001 and P=.004), respectively, for the adherent cohort during the study period, whereas only the systolic blood pressure value improved by an average of 1.6 mm Hg (P=.02) for the nonadherent cohort.

Conclusions

Although we found that patients can achieve high levels of adherence, many experience adherence problems. Although adherence reminder calls help, they may not be sufficient. Telemonitoring lowered blood pressure, as has been observed in clinical trials. Furthermore, blood pressure control was positively associated with adherence.

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.

Effectiveness of a family nurse-led programme on accuracy of blood pressure self-measurement: A randomised controlled trial

AIMS AND OBJECTIVES

To evaluate the effectiveness of a Family Nurse Practitioner (FNP)-led programme on the degree of adherence of current recommendations on home blood pressure self-measurement (HBPM) as compared to routine care and management.

BACKGROUND

HBPM plays an important role for monitoring hypertensive patients; however, patients' adherence to current guidelines is unsatisfactory. A nurse-led training programme in the community setting could be an effective strategy to achieve high level of patients' adherence to recommendations.

DESIGN

A multicentre randomised controlled trial was carried out from September 2016 to September 2017.

METHODS

In total, 170 patients were randomly allocated into the intervention group (n = 83) and the usual care (n = 87). All participants received usual care (written and verbal information on HBPM recommendations); subjects in the intervention group also received 1-hour training session on how to correctly self-measure BP. Clinical trial registration was done (ClinicalTrials.gov.: NCT04681703). The CONSORT checklist for randomised controlled trials was used in this study.

RESULTS

At baseline, the level of adherence to the recommendation was similar in the two groups (p < .05). After 1 month, the adherence significantly increased in the intervention group, where patients were more likely to measure BP at the same hour and from the same arm, in a quiet environment, with the back and uncovered arm supported and the legs uncrossed; recording BP more than once in each measurement session; keeping a diary of blood pressure measurements; use of the appropriate cuff and proper placement of the cuff; and resting for >5 min before performing the measurement (all p < .05).

CONCLUSIONS

The FNP-led programme is effective in improving patients' adherence to guidelines on the correct technique to self-measure BP at home.

RELEVANCE TO CLINICAL PRACTICE

This programme may be added to the existing interventions in the community setting or considered into specifically nurse-led hypertension management models.

Home blood-pressure measurement for the diagnosis and monitoring of arterial hypertension by French general practitioners: a cross-sectional survey in the Auvergne region

Background

Home blood-pressure measurement (HBPM) is recommended for the diagnosis of hypertension and monitoring of patients with hypertension. Since 2013, the French National Health Insurance Body (FNHIB) has promoted HBPM to general practitioners (GPs). The objective of the study was to evaluate the practice of HBPM by French GPs to diagnose and monitor hypertension, 3 years after the beginning of the FNHIB campaign.

Methods

We conducted a postal survey from 7 March to 31 May 2016. All of the 1040 GPs practising in the Auvergne region in France were invited to participate, using a self-reporting questionnaire. We obtained information on the characteristics of the GPs, and their practice regarding the use of HBPM. Use of HBPM was reported as “never, occasionally, regularly and systematically”. Frequency of HBMP use was analysed using multivariate ordered logistic regression model.

Results

A total of 569 (54.7%) GPs responded to the survey. They were 50.3 (± 11.5) years old, 241 (43.0%) were female, and 352 (62.7%) worked in urban areas. Among them, 530 (94.5%) reported the use of HBPM for diagnosis and 519 (92.5%) for monitoring hypertension. To diagnose hypertension, younger GPs (OR = 0.97; 95% CI: 0.95–0.98), GPs practising in a group (OR = 1.45; 95% CI: 1.00–2.10) and in an MHC (OR = 2.09; 95% CI: 1.15–3.78), as compared to GPs with individual practices, and Clinical Tutors, as compared to non-Clinical Tutors, (OR = 1.92; 95% CI: 1.33–2.79) reported more frequent use of HBPM. To manage hypertension, female GPs, as compared to male GPs, (OR=1.47; 95% CI: 1.04–2.06), younger GPs (OR = 0.98; 95% CI: 0.97–0.99), and Clinical Tutors (OR = 1.90; 95% CI: 1.31–2.75) reported more frequent use of HBPM.

Conclusions

Our survey reveals that 3 years after the introduction of the FNHIB incentives, the use of HBPM by participating GPs to diagnose and manage hypertension is well established. A larger survey of GPs from other regions would make it possible to verify whether our results can be extrapolated to France as a whole.

Assessing the routine-practice gap for home blood pressure monitoring among Chinese adults with hypertension

Background

Home blood pressure monitoring (HBPM) is recommended for diagnosis, treatment adjustment and management of most hypertension cases in hypertension guidelines from multiple countries. This study aimed to evaluate HBPM behaviour and explore the routine-practice gap in HBPM among Chinese adults with hypertension.

Methods

Data were collected from 20 communities across three cities and six townships in three provinces (Beijing, Shandong and Jiangsu) in China between October 2014 and November 2014. In total, 2272 patients with hypertension aged ≥35 years that were registered with a primary health station in their local communities were selected by simple random sampling.

Results

Among the 2272 participants, 45.3% owned a home blood pressure (BP) monitor. In addition, 27.5% (625/2272) engaged in HBPM weekly or more frequently. Healthcare providers’ advice was the strongest factor contributing to home BP monitor ownership and weekly HBPM behaviour, with odds ratios of 13.50 and 8.97, respectively. Approximately 4.4% of participants had achieved optimal HBPM regimens (duplicate measurements in the morning and evening for 7 days). Patients with uncontrolled office-measured BP were more likely to conduct HBPM regularly in the morning and evening, measure their BP two or three times in each session and maintain 7 consecutive days of HBPM than patients with controlled office BP (8.8% vs. 5.8%, P = 0.042; 14.3% vs. 8.1%, P = 0.002; and 19.9% vs. 12.4%, P = 0.005, respectively). Only 16.0% (165/1030) of participants actively reported their HBPM readings to doctors.

Conclusion

The HBPM strategies specified in hypertension guidelines are seldom achieved in actual practice in China. Only a small proportion of patients actively participate in using HBPM to enhance their hypertension care. HBPM may be improved by healthcare providers offering specific advice and training.

Understanding the Feasibility, Acceptability, and Efficacy of a Clinical Pharmacist-led Mobile Approach (BPTrack) to Hypertension Management: Mixed Methods Pilot Study

BACKGROUND

Hypertension is a prevalent and costly burden in the United States. Clinical pharmacists within care teams provide effective management of hypertension, as does home blood pressure monitoring; however, concerns about data quality and latency are widespread. One approach to close the gap between clinical pharmacist intervention and home blood pressure monitoring is the use of mobile health (mHealth) technology.

OBJECTIVE

We sought to investigate the feasibility, acceptability, and preliminary effectiveness of BPTrack, a clinical pharmacist-led intervention that incorporates patient- and clinician-facing apps to make electronically collected, patient-generated data available to providers in real time for hypertension management. The patient app also included customizable daily medication reminders and educational messages. Additionally, this study sought to understand barriers to adoption and areas for improvement identified by key stakeholders, so more widespread use of such interventions may be achieved.

METHODS

We conducted a mixed methods pilot study of BPTrack, to improve blood pressure control in patients with uncontrolled hypertension through a 12-week pre-post intervention. All patients were recruited from a primary care setting where they worked with a clinical pharmacist for hypertension management. Participants completed a baseline visit, then spent 12 weeks utilizing BPTrack before returning to the clinic for follow-up. Collected data from patient participants included surveys pre- and postintervention, clinical measures (for establishing effectiveness, with the primary outcome being a change in blood pressure and the secondary outcome being a change in medication adherence), utilization of the BPTrack app, interviews at follow-up, and chart review. We also conducted interviews with key stakeholders.

RESULTS

A total of 15 patient participants were included (13 remained through follow-up for an 86.7% retention rate) in a single group, pre-post assessment pilot study. Data supported the hypothesis that BPTrack was feasible and acceptable for use by patient and provider participants and was effective at reducing patient blood pressure. At the 12-week follow-up, patients exhibited significant reductions in both systolic blood pressure (baseline mean 137.3 mm Hg, SD 11.1 mm Hg; follow-up mean 131.0 mm Hg, SD 9.9 mm Hg; P=.02) and diastolic blood pressure (baseline mean 89.4 mm Hg, SD 7.7 mm Hg; follow-up mean 82.5 mm Hg, SD 8.2 mm Hg; P<.001). On average, patients uploaded at least one blood pressure measurement on 75% (SD 25%) of study days. No improvements in medication adherence were noted. Interview data revealed areas of improvement and refinement for the patient experience. Furthermore, stakeholders require integration into the electronic health record and a modified clinical workflow for BPTrack to be truly useful; however, both patients and stakeholders perceived benefits of BPTrack when used within the context of a clinical relationship.

CONCLUSIONS

Results demonstrate that a pharmacist-led mHealth intervention promoting home blood pressure monitoring and clinical pharmacist management of hypertension can be effective at reducing blood pressure in primary care patients with uncontrolled hypertension. Our data also support the feasibility and acceptability of these types of interventions for patients and providers.

Impact of Self-Monitoring of Blood Pressure on Processes of Hypertension Care and Long-Term Blood Pressure Control

Background Self-monitoring of blood pressure (SMBP) improves blood pressure (BP) outcomes at 12-months, but information is lacking on how SMBP affects hypertension care processes and longer-term BP outcomes. Methods and Results We pooled individual participant data from 4 randomized clinical trials of SMBP in the United Kingdom (combined n=2590) with varying intensities of support. Multivariable random effects regression was used to estimate the probability of antihypertensive intensification at 12 months for usual care versus SMBP. Using these data, we simulated 5-year BP control rates using a validated mathematical model. Trial participants were mostly older adults (mean age 66.6 years, SD 9.5), male (53.9%), and predominantly white (95.6%); mean baseline BP was 151.8/85.0 mm Hg. Compared with usual care, the likelihood of antihypertensive intensification increased with both SMBP with feedback to patient or provider alone (odds ratio 1.8, 95% CI 1.2-2.6) and with telemonitoring or self-management (3.3, 2.5-4.2). Over 5 years, we estimated 33.4% BP control (<140/90 mm Hg) with usual care (95% uncertainty interval 27.7%-39.4%). One year of SMBP with feedback to patient or provider alone achieved 33.9% (28.3%-40.3%) BP control and SMBP with telemonitoring or self-management 39.0% (33.1%-45.2%) over 5 years. If SMBP interventions and associated BP control processes were extended to 5 years, BP control increased to 52.4% (45.4%-59.8 %) and 72.1% (66.5%-77.6%), respectively. Conclusions One year of SMBP plus telemonitoring or self-management increases the likelihood of antihypertensive intensification and could improve BP control rates at 5 years; continuing SMBP for 5 years could further improve BP control.
