Closing the Gap: Digital Innovations to Address Hypertension Disparities.

Significant inequities persist in hypertension detection and control, with minoritized populations disproportionately experiencing organ damage and premature death due to uncontrolled hypertension. Remote blood pressure monitoring combined with telehealth visits (RBPM) is proving to be an effective strategy for controlling hypertension. Yet there are challenges related to technology adoption, patient engagement and social determinants of health (SDoH), contributing to disparities in patient outcomes. This review summarizes the evidence to date for RBPM, focusing on the potential to advance health equity in blood pressure control and the existing levers for largescale implementation. Several studies demonstrate the promise of RBPM programs to address health disparities through: (1) the use of cellular-enabled blood pressure machines that do not require internet access or smart devices to connect readings into the medical record; (2) emphasis on home blood pressure monitoring to illuminate the daily factors that influence blood pressure control, thereby increasing patient empowerment; (3) adoption of standardized algorithms for hypertension management; and (4) integration of services to address SDoH. Multidisciplinary, non-physician care teams that include nurses, pharmacists, and community health workers are integral to this model. However, most studies have not embraced all aspects of RBPM, and implementation is challenging as current payment models do not support the digital components of RBPM or a diverse workforce of hypertension providers. To address hypertension disparities, RBPM programs need to integrate digital technology that is accessible to all users as well as multidisciplinary care teams that attend to the medical and social needs of populations experiencing health inequities.

Behavioral Factors Related to Participation in Remote Blood Pressure Monitoring Among Adults With Hypertension: Cross-Sectional Study.

Remote blood pressure (BP) monitoring (RBPM) or BP telemonitoring is beneficial in hypertension management. People with hypertension involved in telemonitoring of BP often have better BP control than those in usual care. However, most reports on RBPM are from intervention studies. This study aimed to assess participant characteristics and technology health behaviors associated with RBPM participation in a wider population with hypertension. This study will help us understand the predictors of RBPM participation and consider how to increase it. This was a quantitative, cross-sectional survey study of people with hypertension in the United States. The inclusion criteria included people aged ≥18 years with a hypertension diagnosis or who self-reported they have hypertension, had a prescription of at least one hypertension medication, understood the English language, and were willing to participate. The survey included demographics, technology health behaviors, and RBPM participation questions. The survey was self-administered on the Qualtrics platform and followed the CHERRIES (Checklist for Reporting Results of Internet E-Surveys) checklist. The primary dependent variable was participation in RBPM. In total, 507 people with hypertension participated in the survey. The mean age for all respondents was 60 (SD 14.7) years. The respondents were mostly female (306/507, 60.4%), non-Hispanic (483/507, 95.3%), and White (429/507, 84.6%). A little over half of the respondents reported having had hypertension for 5 years or more (287/507, 56.6%). About one-third of participants were aware of RBPM (165/507, 32.5%), and 11.8% (60/507) were enrolled in RBPM. The mean age of those engaging in RBPM and non-RBPM was 46.2 (SD 14.7) and 62 (SD 13.7) years, respectively. The most common reasons for not participating in RBPM were because their health provider did not ask the participant to participate (247/447, 55.3%) and their lack of awareness of RBPM (190/447, 42.5%). Most respondents in the RBPM group measure their BP at home (55/60, 91.7%), and 61.7% (37/60) engage in daily BP measurement, compared with 62.6% (280/447) and 25.1% (112/447), respectively, among the non-RBPM group. A greater number of those in the RBPM group reported tracking their BP measurements with mobile health (mHealth; 37/60, 61.7%) than those in the non-RBPM group (70/447, 15.6%). The electronic health records or patient portal was the most common channel of RBPM communication between the respondents and their health care providers. The significant predictors of participation in RBPM were RBPM awareness (adjusted odds ratio [AOR] 34.65, 95% CI 11.35-150.31; P<.001) and sharing health information electronically with a health provider (AOR 4.90, 95% CI 1.39-21.64; P=.01) among all participants. However, the significant predictor of participation in RBPM among participants who were aware of RBPM was sharing health information electronically with a health provider (AOR 6.99, 95% CI 1.62-47.44; P=.007). Participation in RBPM is likely to increase with increased awareness, health providers' recommendations, and tailoring RBPM services to patients' preferred electronic communication channels.

Comparative Analysis of Color Models for improved rPPG Signals in Remote Blood Pressure Measurement

Abstract The quality of remote photoplethysmography (rPPG) signals presents a significant challenge in contactless optical blood pressure measurement. Feature and morphologybased approaches heavily rely on subtle changes in signal characteristics, but rPPG signals are highly susceptible to noise and interference. This study aims to evaluate rPPG signal quality by assessing correlation with a reference PPG and signal-to-noise ratio (SNR) across various color models and rPPG methods. Analyses are performed under different measurement conditions, accounting for common sources of signal artifacts.

Remote blood pressure monitoring in women at risk of or with hypertensive disorders of pregnancy: A systematic review and meta-analysis.

Remote blood pressure monitoring refers to an organized framework that either allows clinicians to review home-based blood pressure readings and institute management, or provide participants with clear instructions for contacting care teams when blood pressure readings are out of prespecified targets. With widespread uptake of telemonitoring and mobile health in recent years, such models of care have been increasingly described in the literature. This study aimed to review remote blood pressure monitoring in pregnant and postpartum women who are at high-risk for or have an established diagnosis of hypertensive disorders of pregnancy, and its effect on maternal and fetal outcomes, healthcare utilization and psychosocial outcomes. PubMed, Medline, Embase, Cochrane Library, Web of Science and CINAHL databases were searched electronically in June 2024 to their inception. Included studies compared remote blood pressure monitoring with standard care. Remote blood pressure monitoring was pre-defined as any framework for measuring blood pressure remotely in pregnancy, with organized review by clinicians. Published full-text and study abstracts describing randomized controlled trials and observational studies were included. The study population was pregnant women at high-risk for developing pre-eclampsia or postpartum (<6 weeks) women with an established diagnosis of a hypertensive disorder of pregnancy. Remote blood pressure monitoring undertaken in the antenatal and postnatal periods were analyzed separately. This systematic review was conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement. Screening of records and data extraction were independently performed. Data were extracted and analyzed using Review Manager software (version 5.4; Cochrane Collaboration, Copenhagen, Denmark). Risk of bias and quality assessment was performed independently using the Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I) assessment tool and the Cochrane Risk of Bias 2 (RoB2) tool. A total of 18 studies with 28 094 patients were included. Antenatal remote blood pressure monitoring reduces antenatal outpatient visits, antenatal hospital admissions for any cause, and antenatal hospital admissions specifically for hypertension. Importantly, there was no increase in adverse maternal and fetal outcomes, including the likelihood of cesarean section deliveries or induction of labor due to hypertension, composite maternal outcome, growth restriction, neonatal intensive care unit admissions, gestational age at delivery and the composite fetal outcome. Psychosocial outcomes were also not significantly different between the remote blood pressure monitoring and usual care groups. Postpartum remote blood pressure monitoring in women with an established hypertensive disorder of pregnancy led to greater compliance with blood pressure follow-up within 10 days, with no increase in unscheduled hypertension-related presentations, postpartum readmissions or outpatient antihypertensive prescription. Utilizing a model of remote blood pressure monitoring which incorporates organized review and management by clinicians, may reduce antenatal outpatient visits and admissions, without increasing adverse fetal and maternal outcomes, in pregnant women who require frequent monitoring of their blood pressure. In postpartum women with a hypertensive disorder of pregnancy, remote blood pressure monitoring can improve guideline recommended follow-up within 10 days. However, the meta-analysis was hampered by study heterogeneity and a paucity of high-quality evidence. Further randomized controlled trials are needed to confirm the findings of this review and provide recommendations.

Abstract 4138494: Remote Blood Pressure Monitoring and Intervention as a better and cost-effective method of Hypertension control compared to Usual care: A Systematic Review

Introduction/Background: Hypertension is a leading cause of morbidity and mortality. Despite treatment recommendations and encouragement of lifestyle changes, the actual rate of blood pressure control is still not at par. Remote intervention methods have been shown to achieve better rates of blood pressure control utilising lesser resources and lower healthcare costs. We conducted a systematic review by qualitatively evaluating the potential impact of remote monitoring and interventions compared to usual care in controlling Hypertension. Research Question: Are remote monitoring techniques and interventions better than usual in-person blood pressure checks for hypertension control? Methods: We did a comprehensive literature search of Pubmed/MEDLINE, Google scholar, Cochrane central Library, PLOS ONE, ScienceDirect and Clinicaltrials.gov to identify eligible randomised control trials and clinical trials published between July 2013 and May 2025. A Risk of Bias assessment was conducted using Cochrane Risk of Bias tools such as ROB-2 for randomised control trials and ROBINS-1 for cohort studies. This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: Of the 5,185 records analysed, 10 randomised control trials, 1 cohort study and 1 implementation study satisfied our inclusion criteria. Compared to usual care, remote monitoring methods showed significant difference in systolic blood pressure control at 6-12 months in 9 out of 12 studies, while 3 studies did not show any significant difference. Quality of life, physical health, mental health and drug compliance have also shown a significant positive difference in patients. Remote self monitoring interventions were found to be more cost-effective than usual care. They also reduced the load of patients seeking appointments for hypertension control thereby improving the quality of patient care. Conclusion: The management of clinical hypertension is a challenging entity. Conventional methods of regular in-office blood pressure checks are both tedious and resource consuming. Using remote monitoring methods have shown to significantly improve blood pressure control compared to routine methods. It also eliminates white-coat hypertension during follow-up blood pressure checks which leads to more appropriate interventions. Remote monitoring and intervention for hypertension control is time-effective, cost-effective and improves quality of life.

Abstract 4147618: Modality of Research Engagement Among Postpartum Women with Hypertension and High Health-Related Social Needs

Introduction: People of color and non-English speakers are underrepresented in research and disproportionately affected by health-related social needs (HRSNs). Research engagement can be particularly challenging after pregnancy as postpartum care attendance is low. We describe our experience with remote recruitment modalities in a such a population. Methods: The study population included all patients affected by hypertension during a pregnancy who delivered at a large safety-net hospital 1/2022-6/2023. These patients also engaged in 6 weeks of remote blood pressure monitoring postpartum. Patients were contacted between 6 weeks and 12 months post-delivery to complete an online survey regarding HRSNs and provide consent to link survey data to clinical data. The recruitment protocol included initial outreach via the electronic medical record (EMR) patient portal, if available, or else a hard copy letter via mail, followed by a series of text messages then phone calls. All communication was conducted in the patient’s primary language (English, Spanish, or Haitian Creole). Results: We recruited 148 (9.4%) of 1571 patients contacted. Respondents were 51% Black, 39% Latina, 26% White. Table illustrates the comparable rate of recruitment across languages, dominance of EMR as mode of engagement and an illustration of the high rate of complex HRSN among our participants. The most effective recruitment method was EMR communication (57% of total recruitment) followed by text messages (28%). Our Haitian Creole-speaking respondents had the highest rates of HRSN - possibly representing the Haitian migrant crisis affecting Boston in this time period - as well as the highest rate of engaging via EMR messaging. Other domains of HRSN were high among all language groups including trouble affording medication (11-23%) and heating/electric access (21-34%). Conclusions: A diverse postpartum population with a high prevalence of HRSNs is hard to engage in research. Despite presumed digital barriers, EMR and secure text were effective and secure methods of online survey recruitment. Future studies seeking to understand the intersection of health outcomes and HRSNs should consider adding recruitment with EMR to common texting strategies.

Wearable cuffless blood pressure monitoring devices: a commentary.

Hypertension is a growing public challenge as a leading risk factor for cardiovascular disease and all-cause mortality. Reducing overall cardiovascular risk through early screening, initiation of treatment and ongoing monitoring remains a priority in the comprehensive management of hypertension and its complications. Community nurses are ideally positioned to play a crucial role in the early detection of hypertension and providing support for its management. Wearable cuffless devices have the potential for continuous remote blood pressure monitoring. However, there is not enough literature on the validity and usability of wearable cuffless blood pressure devices to justify their use in clinical practice. This commentary critically appraises a systematic review designed to assess the validity, features and clinical usability of wearable cuffless devices, and expands on its findings and their relevance to community nursing and future research.

Selected approaches to the study of social efficiency in the organization of medical care with the use of remote technologies

Introduction. Sociological surveys are a reliable source of information about the quality of medical care provided. Assessing the subjective opinions of all participants in the treatment and preventive process about the organization of medical care allows for timely adjustments to the volume and quality of medical services provided. The study of subjective assessments of medical personnel about the quality of medical care provided determines its effectiveness and requires additional research. The purpose of the study is to study the opinions of medical workers, assess the influence of possible factors on the responses of respondents, in connection with the inclusion of remote blood pressure monitoring in their functional responsibilities. Materials and methods. Study was conducted on the basis of two city clinics of St. Petersburg No. 19 and 91. The materials were data from a sociological survey of medical workers who took part in organizing the provision of medical care using remote blood pressure monitoring to patients of the cardiology follow-up group in the period from 2018 to 2022. Results. An analysis was carried out of the influence of some factors on the respondents’ answers in connection with the inclusion of remote blood pressure monitoring in their functional responsibilities. Conclusion. Data processing showed that, in general, this led to an increase in the satisfaction of medical workers with various aspects of professional activity related to communication processes in the team – improved mutual understanding with colleagues and management and a decrease in the number of conflicts with patients. Regarding factors of labor organization and remuneration, significant resources were noted to determine directions for their solution.

A Pilot Project to Implement a Pharmacist-Managed Remote Blood Pressure Monitoring Service

Background: Clinicians often hesitate to adjust antihypertensive medications based solely on clinic blood pressure (BP) readings. Limitations to obtaining home readings include access to sphygmomanometers and ability to provide accurate, reliable readings upon follow-up. Objective: This study examined whether an online platform linked to remote BP monitoring improved BP management and facilitated effective clinical interventions by pharmacists. Methods: Thirty patients with uncontrolled hypertension were enrolled and provided a remote BP monitor for home use. BP data downloaded to an online platform were monitored by two clinic pharmacists. Daily BP checks were requested (up to twice daily), and pharmacists called patients approximately weekly for 6 months. Through approved protocols, pharmacists individualized interventions to improve patient care. Descriptive statistics were used for demographic and clinical data. Results: The average systolic BP reduction was 39 mmHg (IQR = 17-52.5) for the 21 patients included in analysis. A target BP &lt;140/&lt;90 was achieved by 67%, and 76% had improved BP control. Patients utilized the cuff 2-4 times (n = 10) or &gt;5 times weekly (n = 11). Through 261 patient contact attempts, the pharmacists requested more BP checks (n = 62), changed medications (n = 57), or provided non-pharmacologic counseling (n = 24) most often. Medication changes commonly included dose increases (n = 35) and additional agents (n = 17) for BP control. Spironolactone (n = 5) and thiazide diuretics (n = 5) were the most added medications. Conclusions: Most patients were willing to check their BP when provided with devices. The majority achieved a clinically significant decrease in home BP readings, demonstrating that pharmacist-driven home-monitoring programs can improve the optimization of hypertension regimens.

Abstract P114: Reducing Racial Disparities in Hypertension Control using Multicomponent, Equity-Centered Approach

Background: Black Americans have the highest prevalence of hypertension among all racial or ethnic groups in the United States and are five times more likely to die from hypertension compared to non-Hispanic whites. Perceived discrimination in healthcare, clinician and institutional bias, and socioeconomic and environmental inequities contribute to uncontrolled hypertension in this population. Multilevel, multicomponent interventions have effectively improved blood pressure control among Black Americans but remain inadequately implemented in the clinical setting. An integrated nursing/public health quality improvement study was designed to address this gap between evidence and integration into clinical practice. Methods: Using a one group pre/posttest design, we examined the effect of a 12-week intervention on blood pressure among Black Americans with uncontrolled hypertension aged 18 and older in the primary care setting. Intervention components included remote blood pressure monitoring, weekly phone coaching with culturally congruent care, medication intensification, and a standardized hypertension protocol. Results: The average age of the participants (n=35) was 64 years, and two thirds (n=23) were female (66%). The mean difference in both systolic and diastolic blood pressure decreased significantly (23 mmHg and 11mmHg, t-test –9.736 and –5.502, p-value &lt;.001). At 12 weeks, 87% of participants had achieved blood pressure control. The intervention also significantly improved medication adherence and hypertension knowledge (p-value &lt;.001). Conclusion: A multicomponent, culturally congruent quality improvement intervention significantly improved blood pressure among Black Americans. Implications: Scaled up implementation of multicomponent, equity-centered, culturally congruent approaches are needed to reduce racial disparities in hypertension control.

Assessment of the social effectiveness of providing medical care to patients with a cardiological profile using the method of remote monitoring of blood pressure

BACKGROUND: Assessing social efficiency currently plays a key role in improving the organization of medical care to citizens. Satisfaction with medical care provided is an indicator of the availability of medical care and the effectiveness of healthcare in general. AIM: To assess the social effectiveness of medical care using the method of remote monitoring of blood pressure in cardiac patients based on the results of remote monitoring. MATERIALS AND METHODS: The study materials included data from an anonymous sociological survey of 200 patients who were under dispensary observation and had a history of periods of deterioration in the functional state of the cardiological profile. The questionnaire offered to patients contained six establishing questions, each of which was distributed on a scale balanced from extreme positive to extreme negative assessment. RESULTS AND DISCUSSION: Before conducting remote monitoring, the level of awareness of patients about their own health status, preventive measures, and the use of devices for remote transmission of blood pressure data from the patient to the doctor was investigated. Subsequently, to increase patient awareness, additional information materials on the procedure for interaction be-tween patients and medical workers, as well as about risk factors for the development of cardiovascular diseases and complications from them. The sociological survey was conducted to summarize the results of remote monitoring of patients’ blood pressure and was aimed at studying patients’ opinions on changes in the organization of medical care provided in outpatient settings. CONCLUSION: The data obtained showed that, in general, the degree of achievement of social results after remote blood pressure monitoring increased by 61.0%. Undoubtedly, such an increase in patient satisfaction was achieved as a result of the redistribution of responsibilities between doctors and nurses, as well as a result of well-established participatory interaction between medical workers and patients in terms of remote monitoring of dispensary groups of cardiac patients, instruction in the method of measuring blood pressure and monitoring it indicators in electronic form.

Remote blood pressure management for postpartum hypertension: a cost-effectiveness analysis

Recognizing the importance of close follow-up after hypertensive disorders of pregnancy, many centers have initiated programs to support postpartum remote blood pressure management. This study aimed to evaluate the cost-effectiveness of remote blood pressure management to determine the scalability of these programmatic interventions. This was a cost-effectiveness analysis of using remote blood pressure management vs usual care to manage postpartum hypertension. The modeled remote blood pressure management included provision of a home blood pressure monitor, guidance on warning symptoms, instructions on blood pressure self-monitoring twice daily, and clinical staff to manage population-level blood pressures as appropriate. Usual care was defined as guidance on warning symptoms and recommendations for 1 outpatient visit for blood pressure monitoring within a week after discharge. This study designed a Markov model that ran over fourteen 1-day cycles to reflect the initial 2 weeks after delivery when most emergency department visits and readmissions occur and remote blood pressure management is clinically anticipated to be most impactful. Parameter values for the base-case scenario were derived from both internal data and literature review. Quality-adjusted life-years were calculated over the first year after delivery and reflected the short-term morbidities associated with hypertensive disorders of pregnancy that, for most birthing people, resolve by 2 weeks after delivery. Sensitivity analyses were performed to assess the strength and validity of the model. The primary outcome was the incremental cost-effectiveness ratio, which was defined as the cost needed to gain 1 quality-adjusted life-year. The secondary outcome was incremental cost per readmission averted. Analyses were performed from a societal perspective. In the base-case scenario, remote blood pressure management was the dominant strategy (ie, cost less, higher quality-adjusted life-years). In univariate sensitivity analyses, the most cost-effective strategy shifted to usual care when the cost of readmission fell below $2987.92 and the rate of reported severe range blood pressure with a response in remote blood pressure management was <1%. Assuming a willingness to pay of $100,000 per quality-adjusted life-year, using remote blood pressure management was cost-effective in 99.28% of simulations in a Monte Carlo analysis. Using readmissions averted as a secondary effectiveness outcome, the incremental cost per readmission averted was $145.00. Remote blood pressure management for postpartum hypertension is cost saving and has better outcomes than usual care. Our data can be used to inform future dissemination of and support funding for remote blood pressure management programs.

Implementation of an interprofessional model for the management of postpartum hypertension.

Postpartum hypertension (PPHTN) poses increased risks, including of stroke. Timely assessment and management by clinicians is imperative but challenging. Team-based care involving pharmacists has shown promise in improving blood pressure control, yet its application in PPHTN management remains unexplored. The objective of this study was to determine the impact and feasibility of an interprofessional model for PPHTN management. This initiative implemented a novel interprofessional model at a safety-net hospital to address previous workflow limitations. Ambulatory care pharmacists collaborated with an obstetric nurse (OBRN) and a maternal fetal medicine specialist to manage high-risk patients with PPHTN utilizing electronic consults (e-consults). Data collection and symptom assessment were completed by an OBRN via telemedicine appointments. Pharmacists employed a collaborative practice agreement based on a preestablished algorithm to initiate medications. Data on patient demographics, consult volume, prescriptions, and pharmacist comfort were collected during the first quarter of full integration. Pharmacists completed 55 e-consults and generated 54 prescriptions. The average time spent per chart review was 12.5 minutes, and the average time to completion of e-consults was 54 minutes. Forty-five unique patients received care, who were primarily non-English-speaking and non-Hispanic Black patients. Pharmacists reported moderate to high comfort levels in managing PPHTN based on the algorithm and provided feedback leading to workflow adjustments. Integration of pharmacists into PPHTN care enables prompt medication initiation and titration. This innovative model, involving remote blood pressure monitoring, telemedicine visits with an OBRN, and e-consults completed by pharmacists, ensures delivery of timely and equitable care and improved access across a diverse population.

Impact of Remote Blood Pressure Monitoring Device Connectivity on Engagement Among Pregnant Individuals Enrolled in the Delfina Care Platform: Observational Study.

User engagement with remote blood pressure monitoring during pregnancy is critical to optimize the associated benefits of blood pressure control and early detection of hypertensive disorders of pregnancy. In our study population of pregnant individuals, we found that connected blood pressure cuffs, which automatically sync measures to a monitoring platform or health record, increase engagement (2.13 [95% CI 1.36-3.35] times more measures per day) with remote blood pressure monitoring compared to unconnected cuffs that require manual entry of measures.

Implementation of a Cell-Enabled Remote Blood Pressure Monitoring Program During the Postpartum Period at a Safety-Net Hospital.

Postpartum hypertension is a risk factor for severe maternal morbidity; however, barriers exist for diagnosis and treatment. Remote blood pressure (BP) monitoring programs are an effective tool for monitoring BP and may mitigate maternal health disparities. We aimed to describe and evaluate engagement in a remote BP monitoring program on BP ascertainment during the first 6-weeks postpartum among a diverse patient population. A postpartum remote BP monitoring program, using cell-enabled technology and delivered in multiple languages, was implemented at a large safety-net hospital. Eligible patients are those with hypertensive disorders before or during pregnancy. We describe characteristics of patients enrolled from January 2021 to May 2022 and examine program engagement by patient characteristics. Linear regression models were used to calculate mean differences and 95% CIs between characteristics and engagement metrics. We describe the prevalence of patients with BP ≥140/or >90 mm Hg. Among 1033 patients, BP measures were taken an average of 15.2 days during the 6-weeks, with the last measurement around 1 month (mean: 30.9 days), and little variability across race or ethnicity. Younger maternal age (≤25 years) was associated with less frequent measures (mean difference, -4.3 days [95% CI: -6.1 to -2.4]), and grandmultiparity (≥4 births) was associated with shorter engagement (mean difference, -3.5 days [95% CI, -6.1 to -1.0]). Prevalence of patients with BP ≥140/or >90 mm Hg was 62.3%, with differences by race or ethnicity (Black: 72.9%; Hispanic: 52.4%; White: 56.0%). A cell-enabled postpartum remote BP monitoring program was successful in uniformly monitoring BP and capturing hypertension among a diverse, safety-net hospital population.

Cardiovascular Risk Factor Management After Hypertensive Disorders of Pregnancy.

Hypertensive disorders of pregnancy (HDP) are associated with significantly increased risk of developing future cardiovascular disease (CVD). Obstetricians play a crucial role in CVD prevention for postpartum women and birthing people with HDP because they are primarily responsible for immediate postpartum management and can assist with care transitions to other health care practitioners for long-term management of CVD risk factors. Standardized calculators can be used to evaluate long-term CVD risk, which can help guide intensity of treatment. Emerging technologies such as remote blood pressure monitoring demonstrate promise for improving outcomes among patients with HDP. After HDP, all patients should be advised of their increased CVD risk. A plan should be made to initiate lifestyle modifications and antihypertensive therapy to achieve optimal blood pressure control with a target of lower than 130/80 mm Hg, assess lipids within 2-3 years of delivery, and evaluate for development of type 2 diabetes. Other CVD risk factors such as nicotine use should similarly be identified and addressed. In this review, we summarize the essential components of managing CVD risk after a pregnancy complicated by HDP, including blood pressure monitoring, risk stratification tools, and evidence-based lifestyle recommendations.

Postpartum Ambulatory Blood Pressure Patterns Following New-Onset Hypertensive Disorders of Pregnancy

After a hypertensive disorder of pregnancy, hypertension can worsen in the postpartum period following hospital discharge. Risk factors for ongoing hypertension and associated outcomes have not been well characterized. To identify risk factors and characterize outcomes for individuals with ongoing hypertension and severe hypertension following hospital discharge post partum through a hospital system's remote blood pressure (BP) management program. This cohort study involved a population-based sample of individuals with a new-onset hypertensive disorder of pregnancy (preeclampsia or gestational hypertension) and no prepregnancy hypertension who delivered between September 2019 and June 2021. Participants were enrolled in a remote BP monitoring and management program at a postpartum unit at a referral hospital. Data analysis was performed from August 2021 to January 2023. Inpatient postpartum BP categories. The primary outcomes were readmission and emergency department visits within the first 6 weeks post partum. Logistic regression was used to model adjusted odds ratios (aORs) and 95% CIs. Of 2705 individuals in the cohort (mean [SD] age, 29.8 [5.7] years), 2214 (81.8%) had persistent hypertension post partum after hospital discharge, 382 (14.1%) developed severe hypertension after discharge, and 610 (22.6%) had antihypertensive medication initiated after discharge. Individuals with severe hypertension had increased odds of postpartum emergency department visits (aOR, 1.85; 95% CI, 1.17-2.92) and hospital readmissions (aOR, 6.75; 95% CI, 3.43-13.29) compared with individuals with BP normalization. When inpatient postpartum BP categories were compared with outpatient home BP trajectories to inform optimal thresholds for inpatient antihypertensive medication initiation, there was significant overlap between postdischarge BP trajectories among those with inpatient systolic BP greater than or equal to 140 to 149 mm Hg and/or diastolic BP greater than or equal to 90 to 99 mm Hg and those with systolic BP greater than or equal to 150 mm Hg and/or diastolic BP greater than or equal to 100 mm Hg. This cohort study found that more than 80% of individuals with hypertensive disorders of pregnancy had ongoing hypertension after hospital discharge, with approximately 14% developing severe hypertension. These data support the critical role of remote BP monitoring programs and highlight the need for improved tools for risk stratification and consideration of liberalization of thresholds for medication initiation post partum.

Remote Blood Pressure Monitoring With Social Support for Patients With Hypertension

Hypertension management has traditionally been based on office visits. Integrating remote monitoring into routine clinical practices and leveraging social support might improve blood pressure (BP) control. To evaluate the effectiveness of a bidirectional text monitoring program focused on BP control and medication adherence with and without social support in adults with hypertension. This randomized clinical trial included adults aged 18 to 75 treated at an academic family medicine practice in Philadelphia in 2018 and 2019. Patients had been seen at least twice in the prior 24 months and had at least 2 elevated BP measurements (>150/90 mm Hg or >140/90 mm Hg for patients aged 18-59 years or with diabetes or chronic kidney disease) during visits. All participants had a cell phone with text messaging, offered at least 1 support partner, and were taking maintenance medications to treat hypertension. Patients were randomized 2:2:1 to remote monitoring of BP and medication adherence (RM), remote monitoring of BP and medication adherence with feedback provided to a social support partner (SS), or usual care (UC). Data were analyzed on an intention-to-treat basis between October 14, 2019, and May 30, 2020, and were revisited from May 23 through June 2, 2023. The RM and SS groups received an automatic home BP monitor, 3 weekly texts requesting BP measurements, 1 weekly text inquiring about medication adherence, and a weekly text with feedback. In the SS arm, support partners received a weekly progress report. The UC group received UC through their primary care practice. Clinicians caring for the patients in the intervention groups received nudges via electronic health records to adjust medications when 3 of 10 reported BP measurements were elevated. Patients were followed up for 4 months. The primary outcome was systolic BP at 4 months measured during the final follow-up visit. Secondary outcomes included achievement of normotension and diastolic BP. In all, 246 patients (mean [SD] age, 50.9 [11.4] years; 175 females [71.1%]; 223 Black individuals [90.7%] and 13 White individuals [5.3%]) were included in the intention-to-treat analysis: 100 patients in the RM arm, 97 in the SS arm, and 49 in the UC arm. Compared with the UC arm, there was no significant difference in systolic or diastolic BP at the 4-month follow-up visit in the RM arm (systolic BP adjusted mean difference, -5.25 [95% CI, -10.65 to 0.15] mm Hg; diastolic BP adjusted mean difference, -1.94 [95% CI, -5.14 to 1.27] mm Hg) or the SS arm (systolic BP adjusted mean difference, -0.91 [95% CI, -6.37 to 4.55] mm Hg; diastolic BP adjusted mean difference, -0.63 [95% CI, -3.77 to 2.51] mm Hg). Of the 206 patients with a final BP measurement at 4 months, BP was controlled in 49% (41 of 84) of patients in the RM arm, 31% (27 of 87) of patients in the SS arm, and 40% (14 of 35) of patients in the UC arm; these rates did not differ significantly between the intervention arms and the UC group. In this randomized clinical trial, neither remote BP monitoring nor remote BP monitoring with social support improved BP control compared with UC in adults with hypertension. Additional efforts are needed to examine whether interventions directed at helping patients remember to take their BP medications can lead to improved BP control.
