The role of home blood pressure telemonitoring in managing hypertensive populations

Current situation of telemedicine research for cardiovascular risk in Japan

Hypertension continues to be a principal risk factor for the occurrence of cardiovascular disorders, stroke, and kidney diseases. Although more than 40 million subjects suffer from hypertension in Japan, its optimal control is achieved only a subpopulation of patients, highlighting the need for novel approaches to manage this disorder. Toward the better control of blood pressure, the Japanese Society of Hypertension has developed the Future Plan, in which the application of the state-of-art information and communication technology, including web-based resources, artificial intelligence, and big data analysis, is considered as one of the promising solutions. In fact, the rapid advance of digital health technologies, as well as ongoing coronavirus disease 2019 pandemic, has triggered the structural changes in the healthcare system globally, increasing demand for the remote delivery of the medical services. Nonetheless, it is not entirely clear what evidence exists that support the widespread use of telemedicine in Japan. Here, we summarize the current status of telemedicine research, particularly in the field of hypertension and other cardiovascular risk factors. We note that there have been very few interventional studies in Japan that clearly showed the superiority or noninferiority of telemedicine over standard care, and that the methods of online consultation considerably varied among studies. Clearly, more evidence is necessary for wide implementation of telemedicine in hypertensive patients in Japan, and also those with other cardiovascular risk factors.

Differentiated effects and determinants of home blood pressure telemonitoring: lessons from a three-year cohort in Anhui Jieshou, China

BACKGROUND

Home blood pressure telemonitoring (HBPT) is witnessing rapid diffusion worldwide. Contemporary studies documented mainly short-term (6-12 month) effects of HBPT with little data about its uptake.

OBJECTIVE

This study aims to explore 3-year use and determinants of HBPT and its interactions with systolic and diastolic blood pressure (SBP/DBP) and blood pressure (BP) control rate.

METHODS

The study used HBPT records from a 3-year cohort of 5658 hypertensive patients in Anhui Jieshou, China and data from a structured household survey of a random sample (n=3005) from the cohort. The data analysis comprised: calculation and presentation, in time-line trajectories, rates of monthly active HBPT and mean SBP/DBP for overall and subgroups of patients with varied start-month SBP/DBP; and multivariable linear, logistics and percentile regression analysis using SBP/DBP, BP control rate and yearly times of HBPT as the dependent variable respectively.

RESULTS

HBPT followed mixed changes in mean monthly SBP/DBP for varied patient groups. The magnitude of changes ranged from -43 to +39 mmHg for SBP and -27 to +15 mmHg for DBP. The monthly rates of active HBPT all manifested a rapid and then slower and slower decline. When controlled for commonly researched confounders, times of HBPT in the last year were found with decreasing correlation coefficients for SBP/DBP (being decreased from 0.10 to -0.35 and from 0.11 to -0.35 respectively) and for BP control rate (from 0.53 to -0.62).

CONCLUSIONS

HBPT had major and "target-converging" effects on SBP/DBP. The magnitude of changes was much greater than have commonly reported. BP, variation in BP and time were the most important determinants of HBPT uptake; while age, education, duration of hypertension, family history and diagnosis of hypertension complications were also linked to the uptake but at apparently weaker strength. There is a clear need for differentiated thinking over application and assessment of HBPT and for identifying and correcting/leveraging potential outdated/new opportunities or beliefs.

Comparative effect of eHealth interventions on hypertension management-related outcomes: A network meta-analysis

BACKGROUND

Increasingly, health professionals and patients have begun to be involved in eHealth interventions to assist in the self-management of hypertension. Therefore, this study was aimed at comparing the effect of different types of eHealth interventions (phone calls, blood pressure telemonitoring, emails, web-site, smartphone-app, short message service (SMS) and more than two eHealth interventions) on reducing systolic and diastolic blood pressure, increasing adherence to medication treatment, improving physical activity compliance, controlling blood pressure, and improving quality of life (QoL).

METHODS

A systematic search in MEDLINE (via PubMed), EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science databases was conducted to identify experimental studies addressing the effect of eHealth interventions on the self-management of hypertension. Comparative evaluation of the eHealth interventions effect were performed by conducting a standard pairwise meta-analysis and a network meta-analysis for direct and indirect comparisons between eHealth interventions and control/non-intervention.

RESULTS

Fifty-one studies were included in the analysis showing a moderate effect size for more than two types of eHealth interventions (-0.46; 95%CI: -0.64, -0.27, p < 0.001 and -0.29; 95%CI: -0.46, -0.13, p < 0.001), phone calls (-0.37; 95%CI: -0.57, -0.17, p < 0.001 and -0.29; 95%CI: -0.52, -0.07, p = 0.011) and smartphone-app (-0.26; 95%CI: -0.50, -0.01, p = 0.040 and -0.40; 95%CI: -0.70, -0.10, p = 0.010) on reducing both systolic and diastolic blood pressure, respectively. Additionally, i) smartphone-app improved medication adherence by 45%; ii) more than two types of eHealth interventions and emails improved physical activity compliance by 18% and 57% respectively; ii) more than two types of eHealth interventions, phone calls, blood pressure telemonitoring, website and SMS improved blood pressure control between 16% and 30%; and iv) blood pressure telemonitoring showed a week effect on QoL CONCLUSIONS: Our study reported eHealth to be a suitable intervention for the self-management of hypertension. Considering our results and the population's accessibility to eHealth devices, eHealth could be a useful and largely scalable tool for the self-management of hypertension.

Optimizing mother-baby wellness during the 2019 coronavirus disease pandemic: A case for telemedicine

Background:

The 2019 coronavirus disease pandemic poses unique challenges to healthcare delivery. To limit the exposure of providers and patients to severe acute respiratory syndrome coronavirus 2, the Centers for Disease Control and Prevention encourages providers to use telehealth platforms whenever possible. Given the maternal mortality crisis in the United States and the compounding 2019 coronavirus disease public health emergency, continued access to quality preconception, prenatal, intrapartum, and postpartum care are essential to the health and well-being of mother and baby.

Objective:

This commentary explores unique opportunities to optimize virtual obstetric care for low-risk and high-risk mothers at each stage of pregnancy.

Methods:

In this review paper, we present evidence-based literature and tools from first-hand experience implementing telemedicine in obstetric care clinics during the pandemic.

Results:

Using the best evidence-based practices with telemedicine, health care providers can deliver care in the safest, most respectful, and appropriate way possible while providing the critical support necessary in pregnancy. In reviewing the literature, several studies endorse the implementation of specific tools outlined in this article, to facilitate the implementation of telemedicine. From a quality improvement standpoint, evidence-based telemedicine provides a solution for overburdened healthcare systems, greater confidentiality for obstetric services, and a personalized avenue for health care providers to meet maternal health needs in the pandemic.

Conclusion:

During the COVID-19 pandemic, continued access to quality prenatal, intrapartum, and postpartum care are essential to the health and well-being of mother and baby.

Cardiovascular Disease and Coronavirus Disease 2019: Epidemiology, Management, and Prevention

Purpose of Review

Coronavirus disease 2019 (COVID-19) has become a global pandemic associated with significant morbidity and mortality. This review summarizes findings up to date on the relationship between cardiovascular disease (CVD) and COVID-19.

Recent Findings

Preexisting CVD is a common condition among patients with COVID-19 and is associated with increased disease severity and mortality. Conversely, COVID-19 has various clinical manifestations on cardiovascular system, including thrombotic events and cardiac dysfunction. The pandemic has impacted healthcare utilization among patients with CVD, which may have led to potential delay in access to the healthcare system during acute events not directly COVID-19-related.

Summary

While COVID-19 vaccine is being developed and distributed, controlling CVD risk factors and adherence to recommendations of existing immunization (e.g., influenza vaccine) are key in protecting the health of individuals with CVD during the COVID-19 pandemic. Further research is needed to understand the epidemiological and pathophysiological basis for the interaction between CVD and COVID-19.

Global epidemiology, health burden and effective interventions for elevated blood pressure and hypertension

High blood pressure is one of the most important risk factors for ischaemic heart disease, stroke, other cardiovascular diseases, chronic kidney disease and dementia. Mean blood pressure and the prevalence of raised blood pressure have declined substantially in high-income regions since at least the 1970s. By contrast, blood pressure has risen in East, South and Southeast Asia, Oceania and sub-Saharan Africa. Given these trends, the prevalence of hypertension is now higher in low-income and middle-income countries than in high-income countries. In 2015, an estimated 8.5 million deaths were attributable to systolic blood pressure >115 mmHg, 88% of which were in low-income and middle-income countries. Measures such as increasing the availability and affordability of fresh fruits and vegetables, lowering the sodium content of packaged and prepared food and staples such as bread, and improving the availability of dietary salt substitutes can help lower blood pressure in the entire population. The use and effectiveness of hypertension treatment vary substantially across countries. Factors influencing this variation include a country's financial resources, the extent of health insurance and health facilities, how frequently people interact with physicians and non-physician health personnel, whether a clear and widely adopted clinical guideline exists and the availability of medicines. Scaling up treatment coverage and improving its community effectiveness can substantially reduce the health burden of hypertension.

Human Errors in Automated Office Blood Pressure Measurement: Still Room for Improvement

In this review of the literature and commentary, we examine the literature on automated blood pressure (BP) measurements in the office and clinic. Our purpose is to revisit issues as to the pros and cons of automated BP measurement published in Hypertension in June 2020 and to identify areas needing additional research. Despite initial reservations about automated BP, it is here to stay. A number of experts suggest that human error will be reduced when we move from the more complex skills required by aneroid sphygmomanometer measurement to the fewer skills and steps required by automated BP measurement. Our review indicates there is still need for reduction in errors in automated BP assessment, for example, retraining programs and monitoring of assessment procedures. We need more research on the following questions: (1) which classes of health care providers are least likely to measure BP accurately, usually by ignoring necessary steps; (2) how accurate is BP assessment by affiliated health care providers for example the dental office, the optometrist; and (3) why do some dedicated and well-informed health care professionals fail to follow simple directions for automated BP measurement? We offer additional solutions for improving automated BP assessment in the office and clinic.

Telehealth: improving maternity services by modern technology

Hypertension is considered one of the most common medical disorders causing complexities in pregnancy. It could be a newly developed pregnancy-induced hypertension (PIH) or a pre-existing hypertension developing into superimposed pre-eclamptic toxaemia. PIH affects approximately 10% of pregnancies and can have a serious impact on both maternal and fetal well-being; hence requires frequent monitoring and timely intervention. National Institute for Health and Care Excellence (NICE) guidelines recommends once or twice weekly monitoring of blood pressure for such patients. The required frequent monitoring comes with certain implications for patients and healthcare services. An average patient with PIH would need to see her healthcare provider once or twice a week until delivery and 6 weeks thereafter. This certainly increases pressure on limited National Health Service (NHS) resources. Home-based monitoring using Telehealth technology can represent a potential solution for achieving good-quality care for the patient without increasing the workload for healthcare providers. We used 'Florence', a text-based technology platform to support home monitoring. We tested its acceptability, feasibility and safety to replace face-to-face appointments for blood pressure monitoring in selected patients with PIH. We implemented our project in three progressive phases using a plan, do, study, act methodology. Florence, telehealth technology was used for blood pressure monitoring instead of face-to-face appointments, and the effect of this innovative technology on the services and the patient experience was studied and necessary modifications were made before progression into the next phase. We recruited 75 patients over 12 months through the progressive phases and replaced around 800 face-to-face appointments by remotely supervised monitoring sessions with Florence successfully, with improved care and patient satisfaction. We also achieved better compliance with the NICE guidelines for blood pressure monitoring in PIH. Our project concluded that Telehealth can be a potential solution for improving care in maternity services, with lesser burden on NHS resources.

Evidence and Recommendations on the Use of Telemedicine for the Management of Arterial Hypertension: An International Expert Position Paper

Telemedicine allows the remote exchange of medical data between patients and healthcare professionals. It is used to increase patients' access to care and provide effective healthcare services at a distance. During the recent coronavirus disease 2019 (COVID-19) pandemic, telemedicine has thrived and emerged worldwide as an indispensable resource to improve the management of isolated patients due to lockdown or shielding, including those with hypertension. The best proposed healthcare model for telemedicine in hypertension management should include remote monitoring and transmission of vital signs (notably blood pressure) and medication adherence plus education on lifestyle and risk factors, with video consultation as an option. The use of mixed automated feedback services with supervision of a multidisciplinary clinical team (physician, nurse, or pharmacist) is the ideal approach. The indications include screening for suspected hypertension, management of older adults, medically underserved people, high-risk hypertensive patients, patients with multiple diseases, and those isolated due to pandemics or national emergencies.

ECONOMIC JUSTIFICATION OF THE APPLICATION OF THE AUTOMATIC REMOTE BLOOD PRESSURE MONITORING

Introduction. Among the priorities of the strategic development of the health care system there is the telemedicine technologies implementation. Material and methods. The project was developed in the Penza State University. For the economic justification of the remote BP monitoring, the project technological scheme has been prepared, the market capacity has been assessed and competition has been analyzed, the business model and financial model of the project have been developed, and risks have been evaluated. Results. The project is deployed at the base and with the participation of the budget medical institution. The patient is provided with a tonometer with built-in GSM or blutooth module. After the patient’s BP has been measured, the data in an encrypted format is transmitted to the remote monitoring center and stored in the cloud base. For each patient, the doctor sets target and individual thresholds for blood pressure. Intermediate monitoring of BP is carried out by paramedical personnel who, in case of deviations from reference values, notify the attending physician. The patient receives feedback in the form of SMS-messages to his mobile phone: time for BP measuring, taking drugs and recommendations for the therapy correction. Payment is carried out according to the approved Mandatory Medical Insurance Fund tariff. Conclusion. The introduction of remote blood pressure monitoring will reduce the cost of providing medical care by reducing the number of hypertension complications, open up prospects for research and development of medical professionals. Fundamentally new conditions will arise for the study of chronopharmacology of antihypertensive drugs in patients with hypertension.

Young African American women’s participation in an m-Health study in cardiovascular risk reduction: Feasibility, benefits, and barriers

Background:

Young black women have an increased risk of cardiovascular disease, and thus identifying innovative prevention strategies is essential. A potential preventive strategy is mobile health; however, few studies have tested this strategy in young black women.

Aim:

The purpose of this study was to assess the feasibility of a mobile health intervention through a digital application to reduce cardiovascular disease risk factors in young black women, and identify benefits and barriers to participation.

Methods:

Forty black women aged 25–45 years completed four sessions of cardiovascular disease risk reduction education and a six-month smartphone cardiovascular disease risk reduction monitoring and coaching intervention, targeting heart-healthy behavior modifications. At follow-up, women responded to a semi-qualitative online survey assessing the user-friendliness and perceived helpfulness of the intervention.

Results:

Of 40 women, 38 completed the follow-up survey. Sixty per cent of participants reported that the applications were easy or very easy to maintain, 90% reported that the application was easy or very easy to use. Over 60% observed that their family’s nutrition improved “a lot” or “a medium amount,” and many participants noted positive changes in their children’s diets. Only 8% of participants cited time or cost required to prepare healthy foods as barriers to implementing dietary changes.

Conclusions:

The m-Health intervention was feasible as a means of cardiovascular disease risk reduction for young black women. In addition, we found that targeting women provided indirect benefits for other family members, especially children. Most of the participants did not encounter systemic barriers to participation, suggesting that mobile health interventions can be effective tools to improve health behaviors in vulnerable populations.

Assessment of Blood Pressure: Techniques and Implications From Clinical Trials

Hypertension is a global health problem and without adequate diagnosis and treatment is a risk factor for morbidity and mortality. Proper assessment of blood pressure is key to diagnosis and management of hypertension. Different methods of measurement are available for use and varying techniques are applied to patient care. Understanding the proper methods of blood pressure measurement both in and out of the physician's office is crucial for providing appropriate care to an individual patient. In addition, understanding the techniques used in research, on which current guidelines are based, is critical for proper application to daily practice. In this article, we review the types of blood pressure measurement techniques, discuss the benefits and limitations to each, explore future technological advances in measurement devices, and provide insight into research techniques, which ultimately guide our practice.

Implementation and barriers to uptake of interactive voice response technology aimed to improve blood pressure control at a large academic medical center

OBJECTIVES

Blood pressure control among patients with hypertension is a widely recognized quality metric, but many large health systems fail to reach targets set by the Healthcare Effectiveness Data and Information Set. We developed an interactive voice response (IVR) system called the "Mobile You Blood Pressure Program" at a large academic medical center and linked it to the health system's electronic health record (EHR). The goal of the program was to capture home blood pressure readings in the EHR and to alert ambulatory care clinical pharmacists automatically of readings below or above clinical thresholds through direct messaging in the EHR. The goal of this report is to describe implementation of IVR, initial patient participation rates, and pharmacist-identified barriers to patient enrollment.

SETTING

Ambulatory care clinical pharmacist specialists' practice in 14 clinics in family medicine and internal medicine at Michigan Medicine, an academic health system serving more than 24,000 patients with a diagnosis of hypertension.

PRACTICE DESCRIPTION

This study describes implementation and initial patient enrollment in IVR linked to the EHR for home blood pressure monitoring.

EVALUATION

We tracked the number of hypertensive patients enrolled and IVR call completion rates between September 2017 and February 2018. We also assessed pharmacist-identified barriers to patient enrollment during 2 separate 2-week intervals in January and February 2018.

RESULTS

Between September 1, 2017, and February 28, 2018, a total of 71 patients were enrolled from 14 clinics. Patients were scheduled for 1-3 IVR calls per week focusing on medication adherence and blood pressure control. A total of 936 IVR phone calls were made, with 488 (52%) calls completed. Access to a validated home blood pressure monitor was the largest pharmacist-identified barrier to patient enrollment.

CONCLUSIONS

The IVR Mobile You Blood Pressure Program represents a new application of digital technology within our health system. Pharmacist-identified barriers to patient participation included access to a validated home blood pressure monitor.

Feasibility of Telemonitoring Blood Pressure in Patients With Kidney Disease (Oxford Heart and Renal Protection Study-1): Observational Study

Background

Blood pressure (BP) is a key modifiable risk factor for patients with chronic kidney disease (CKD), with current guidelines recommending strict control to reduce the risk of progression of both CKD and cardiovascular disease. Trials involving BP lowering require multiple visits to achieve target BP, which increases the costs of such trials, and in routine care, BP measured in the clinic may not accurately reflect the usual BP.

Objective

We sought to assess whether a telemonitoring system for BP (using a Bluetooth-enabled BP machine that could transmit BP measurements to a tablet device installed with a bespoke app to guide the measurement of BP and collect questionnaire data) was acceptable to patients with CKD and whether patients would provide sufficient BP readings to assess variability and guide treatment.

Methods

A total of 25 participants with CKD were trained to use the telemonitoring equipment and asked to record BP daily for 30 days, attend a study visit, and then record BP on alternate days for the next 60 days. They were also offered a wrist-worn applanation tonometry device (BPro) which measures BP every 15 minutes over a 24-hour period. Participants were given questionnaires at the 1- and 3-month time points; the questionnaires were derived from the System Usability Scale and Technology Acceptance Model. All eligible participants completed the study.

Results

Mean participant age was 58 (SD 11) years, and mean estimated glomerular filtration rate was 36 (SD 13) mL/min/1.73m2. 13/25 (52%) participants provided >90% of the expected data and 18/25 (72%) provided >80% of the expected data. The usability of the telemonitoring system was rated highly, with mean scores of 84.9/100 (SE 2.8) after 30 days and 84.2/100 (SE 4.1) after 90 days. The coefficient of variation for the variability of systolic BP telemonitoring was 9.4% (95% CI 7.8-10.9) compared with 7.9% (95% CI 6.4-9.5) for the BPro device, P=.05 (and was 9.0% over 1 year in a recently completed trial with identical eligibility criteria), indicating that most variation in BP was short term.

Conclusions

Telemonitoring is acceptable for patients with CKD and provides sufficient data to inform titration of antihypertensive therapies in either a randomized trial setting (comparing BP among different targets) or routine clinical practice. Such methods could be employed in both scenarios and reduce costs currently associated with such activities.

Telephone Support and Telemonitoring for Low-Income Older Adults

The objective of the current pilot study was to determine whether nurse-led telephone counseling improves health behavior, self-care, and physiological indices for low-income older adults using a telemonitoring system. The control group (n = 15) was provided with weekly health education only, and the intervention group (n = 20) was given additional telephone support by nurses. At baseline and 8 weeks, data on health and self-care behaviors were collected using a self-reported questionnaire, and blood pressure and fasting blood glucose levels were assessed. Nurse-led telephone support had a medium effect on improving health behavior (Cohen's d = 0.58, 95% confidence interval [CI] [-0.10, 1.27]), reducing systolic blood pressure (Cohen's d = -0.61, 95% CI [-1.29, 0.08]), and improving self-care behavior for hypertension (Cohen's d = 1.16, 95% CI [0.05, 2.27]). Findings support that nurse-led telephone support may be effective for improvements in health behavior, systolic blood pressure, and hypertension self-care in disadvantaged older adults under remote monitoring. Further studies are needed to obtain a powered sample size and investigate the long-term effects of personalized elements surrounding telehealth in community-based settings.

Personalized Hypertension Management Using Patient-Generated Health Data Integrated With Electronic Health Records (EMPOWER-H): Six-Month Pre-Post Study

BACKGROUND

EMPOWER-H (Engaging and Motivating Patients Online With Enhanced Resources-Hypertension) is a personalized-care model facilitating engagement in hypertension self-management utilizing an interactive Web-based disease management system integrated with the electronic health record. The model is designed to support timely patient-provider interaction by incorporating decision support technology to individualize care and provide personalized feedback for patients with chronic disease. Central to this process were patient-generated health data, including blood pressure (BP), weight, and lifestyle behaviors, which were uploaded using a smartphone.

OBJECTIVE

The aim of this study was to evaluate the program among patients within primary care already under management for hypertension and with uncontrolled BP.

METHODS

Using a 6-month pre-post design, outcome measures included office-measured and home-monitored BP, office-measured weight, intervention contacts, diet, physical activity, smoking, knowledge, and health-related quality of life.

RESULTS

At 6 months, 55.9% of participants (N=149) achieved office BP goals (<140/90 mm Hg; P<.001) and 86.0% achieved clinically meaningful reduction in office BP (reduction in systolic BP [SBP] ≥5 mm Hg or diastolic BP [DBP] ≥3 mm Hg). At baseline, 25.2% of participants met home BP goals (<135/85 mm Hg), and this percentage significantly increased to 71.4% (P<.001) at 6 months. EMPOWER-H also significantly reduced both office and home SBP and DBP, decreased office-measured weight and consumption of high-salt and high-fat foods (all P<.005), and increased intake of fruit and vegetables, minutes of aerobic exercise, and hypertension knowledge (all P<.05). Patients with higher home BP upload frequencies had significantly higher odds of achieving home BP goals. Patients receiving more total intervention, behavioral, pharmaceutical contacts had significantly lower odds of achieving home BP goals but higher improvements in office BP (all P<.05).

CONCLUSIONS

EMPOWER-H significantly improved participants' office-measured and home-monitored BP, weight, and lifestyle behaviors, suggesting that technologically enabled BP home-monitoring, with structured use of patient-generated health data and a personalized care-plan facilitating patient engagement, can support effective clinical management. The experience gained in this study provides support for the feasibility and value of using carefully managed patient-generated health data in the day-to-day clinical management of patients with chronic conditions. A large-scale, real-world study to evaluate sustained effectiveness, cost-effectiveness, and scalability is warranted.

A coordinated PCP-Cardiologist Telemedicine Model (PCTM) in China's community hypertension care: study protocol for a randomized controlled trial

BACKGROUND

Hypertension is a major risk factor for cardiovascular disease, and its control rate has remained low worldwide. Studies have found that telemonitoring blood pressure (BP) helped control hypertension in randomized controlled trials. However, little is known about its effect in a structured primary care model in which primary care physicians (PCPs) are partnering with cardiology specialists in electronic healthcare data sharing and medical interventions. This study aims to identify the effects of a coordinated PCP-cardiologist model that applies telemedicine tools to facilitate community hypertension control in China.

METHODS/DESIGN

Patients with hypertension receiving care at four community healthcare centers that are academically affiliated to Shanghai Chest Hospital, Shanghai JiaoTong University are eligible if they have had uncontrolled BP in the previous 3 months and access to mobile Internet. Study subjects are randomly assigned to three interventional groups: (1) usual care; (2) home-based BP telemonitor with embedded Global System for Mobile Communications (GSM) module and unlimited data plan, an app to access personal healthcare record and receive personalized lifestyle coaching contents, and proficiency training of their use; or (3) this plus coordinated PCP-cardiologist care in which PCPs and cardiologists share data via a secure CareLinker website to determine interventional approaches. The primary outcome is mean change in systolic blood pressure over a 12-month period. Secondary outcomes are changes of diastolic blood pressure, HbA1C, blood lipids, and medication adherence measured by the eight-item Morisky Medication Adherence Scale.

DISCUSSION

This study will determine whether a coordinated PCP-Cardiologist Telemedicine Model that incorporates the latest telemedicine technologies will improve hypertension care. Success of the model would help streamline the present community healthcare processes and impact a greater number of patients with uncontrolled hypertension.

Telemedicine and M-Health in Hypertension Management: Technologies, Applications and Clinical Evidence

Electronic processes and communication technologies are more and more often employed to provide healthcare services to caregivers and their patients. Such solutions are currently referred as e-health, the most popular and widely distributed being those based on telemedicine and mobile health (m-health). A specific application of telemedicine for hypertension management is blood pressure telemonitoring (BPT), which allows remote data transmission of BP and additional information on patients' health status from their living site or from a community setting to the doctor's office or the hospital. Several randomized studies have documented a significant BP reduction with regular BPT compared to usual care, particularly in high risk hypertensive patients. Additional benefits are observed when BPT is offered under the supervision of a team of healthcare professionals, including a community pharmacist. BPT may also be provided in the context of m-health solutions, which commonly include wireless diagnostic and clinical decision support tools. M-health has the potential to promote patient's self-management, as a complement to the doctor's intervention, and encourage greater participation in medical decision making. Current statistics show that half of smartphone owners gather health information through their phone and 19 % use a health app. In case of hypertensive patients the most popular apps are those with tracking function, including BPT. Thus, e-health, and in particular BPT and m-health, are progressively gaining a key role in the management of hypertensive patients, having the potential to improve the quality of the delivered care and to more effectively prevent cardiovascular consequences of high BP.

The Use of Behavior Change Techniques and Theory in Technologies for Cardiovascular Disease Prevention and Treatment in Adults: A Comprehensive Review

This review examined the use of health behavior change techniques and theory in technology-enabled interventions targeting risk factors and indicators for cardiovascular disease (CVD) prevention and treatment. Articles targeting physical activity, weight loss, smoking cessation and management of hypertension, lipids and blood glucose were sourced from PubMed (November 2010-2015) and coded for use of 1) technology, 2) health behavior change techniques (using the CALO-RE taxonomy), and 3) health behavior theories. Of the 984 articles reviewed, 304 were relevant (240=intervention, 64=review). Twenty-two different technologies were used (M=1.45, SD=+/-0.719). The most frequently used behavior change techniques were self-monitoring and feedback on performance (M=5.4, SD=+/-2.9). Half (52%) of the intervention studies named a theory/model - most frequently Social Cognitive Theory, the Trans-theoretical Model, and the Theory of Planned Behavior/Reasoned Action. To optimize technology-enabled interventions targeting CVD risk factors, integrated behavior change theories that incorporate a variety of evidence-based health behavior change techniques are needed.

The role of telemedicine in hypertension management: focus on blood pressure telemonitoring

This review aims at updating and critically assessing the role of telemedicine, and in particular, of home blood pressure telemonitoring (HBPT), in the management of the hypertensive patient. Result from several randomized trials suggest that HBPT represents a promising tool for improving blood pressure (BP) control of hypertensive patients, in particular, those at high risk. Most studies documented a significant BP reduction with regular HBPT compared to usual care. HBPT interventions showed a very high degree of acceptance by patients, helped improving the patients' quality of life, and were associated with lower medical costs than standard care, even though such costs were offset by those of the technology, thus reducing the overall cost-effectiveness of HBPT. The high heterogeneity of the technologies, study designs, and type of patients in the various studies suggest that further well-designed, large cohort, prospective studies are needed to identify key elements of HBPT approach to be able to give impact on specific outcomes. Likely, patients who need a constant monitoring of multiple vital signs and a tight BP control, such as high risk patients with chronic diseases (ischemic heart disease or heart failure, diabetes, etc.), as well as non-adherent patients, may particularly benefit from HBPT. In general, HBPT can be an advantageous choice when a network among healthcare professionals (doctors, nurses, and pharmacists) is needed to improve the screening and management of hypertension and related comorbidities and to achieve an effective prevention of cardiovascular diseases in the community.

Impaired deformability of circulating erythrocytes obtained from nondiabetic hypertensive patients: investigation by a nickel mesh filtration technique

Introduction

Hypertension is associated with microcirculatory disturbance, and erythrocyte deformability is a major determinant of the microcirculation. However, impairment of erythrocyte deformability in hypertensive patients in relation to antihypertensive treatment is unclear. The present study aimed to investigate this impairment in hypertensive patients under treatment using a highly sensitive and quantitative nickel mesh filtration technique.

Methods

Deformability was evaluated by filterability, defined as the flow rate of a hematocrit-adjusted erythrocyte suspension relative to that of saline under a specific filtration pressure in a pressure-flow curve obtained by continuous filtration. Baseline characteristics of hypertensive patients (n = 101) and age-matched normotensive subjects (n = 14) were obtained from medical records, and diabetic patients were excluded.

Results

Erythrocyte deformability in the hypertensive group was significantly (p = 0.010) lower (87.8 ± 2.2 %) than that of the normotensive group (89.4 ± 1.7 %) and inversely proportional (r = −0.303, p = 0.002) to the mean blood pressure (BP) measured on blood sampling for the filtration study. Stepwise multiple regression analysis demonstrated that this impairment was mostly attributable to the mean BP (p = 0.001), whereas current smoking and episodes of stroke or coronary artery disease were not contributors.

Discussion

These findings indicate that erythrocyte deformability is impaired in the hypertensive patients, which depends on the current BP control rather than target organ damage.

The pharmacist and the management of arterial hypertension: the role of blood pressure monitoring and telemonitoring

Randomized controlled trials have documented that a team of health care professionals which includes a physician, a nurse and a community pharmacist may improve the benefit and adherence of anti-hypertensive therapy. If such a health care model relies on blood pressure telemonitoring, it can promote a stronger relationship between health care professionals and patients, and further improve BP control of hypertension. The major benefit of this collaborative approach is to center the patient's management in a tailored way, providing comprehensive and preventive care based on health information technologies. In this review, the authors summarize recent clinical studies that evaluate the role of the community pharmacist in BP measurements, and in hypertension screening and control. The authors also describe the advantages of using blood pressure telemonitoring in home and ambulatory settings to evaluate potential alternatives to primary care in hypertension management.
