RESUMO
CONTEXT: Self-measured blood pressure monitoring (SMBP) with clinical support is effective at reducing blood pressure for people with hypertension. Although strengths and challenges around SMBP are well-documented, few studies describe the complexities of real-world implementation of SMBP with clinical support in the Federally Qualified Health Center (FQHC) setting. PROGRAM: Between 2019 and 2023, the Ohio Department of Health funded the Ohio Association of Community Health Centers to manage a multiyear quality improvement (QI) project with 21 FQHCs. The project aimed to improve the identification and management of patients with hypertension, diabetes, and prediabetes. This study focuses on the activities implemented to provide SMBP support to patients with hypertension. IMPLEMENTATION: FQHCs implemented clinical SMBP support using multiple roles, approaches, and resources. FQHCs established a process to identify patients eligible for SMBP support, provide blood pressure monitors, train patients on SMBP, track blood pressure readings, follow up with patients, and connect patients to resources. EVALUATION: External evaluators interviewed 13 staff members within seven FQHCs from the QI project. Interviewed FQHCs were located across Ohio and represented urban, rural, suburban, and Appalachian areas. Clinical activities to support SMBP, facilitators, and barriers were identified with thematic analysis. The National Association of Community Health Centers SMBP Implementation Toolkit was used as a framework to assess SMBP activities. Facilitators included team-based care, health information technology capacity, funding for blood pressure monitors and staff time, leadership and staff support, and external support. Barriers included technology challenges, staffing shortages, low patient engagement, sustainability, and the COVID-19 pandemic. DISCUSSION: This study demonstrates how FQHCs can use a variety of staff, processes, and resources to implement clinical SMBP support across a range of geographic regions. To facilitate this, FQHCs and patients may need more comprehensive insurance coverage of blood pressure monitors, reimbursement for staff time, and technology support.

Unlabelled: 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.

Central blood pressure confers cardiovascular risk prediction ability, but whether the association between central systolic blood pressure (cSBP) and cardiovascular endpoints is independent of peripheral systolic blood pressure (pSBP) remains controversial. This systematic review and meta-analysis aim to investigate the associations between cSBP and cardiovascular endpoints in models including and excluding pSBP, respectively. Observational studies assessing the risk of composite cardiovascular endpoints with baseline cSBP were searched in PubMed, Embase, Scopus, Web of Science, and Cochrane Library to May 31, 2022. Risk of bias was assessed by the Newcastle-Ottawa Quality Assessment Scale, and random-effects models were used to pool estimates. Finally, 48 200 participants from 19 studies with a mean age of 59.0 ± 6.9 years were included. Per 10 mmHg increase of cSBP was associated with higher risk of composite cardiovascular outcomes (risk ratio [RR]: 1.14 [95%CI 1.08-1.19]) and cardiovascular death (RR: 1.18 [95%CI 1.08-1.30]), and the associations still existed after adjusting for pSBP (RR: 1.13 [95%CI 1.05-1.21] for composite cardiovascular endpoints; RR: 1.25 [95%CI 1.09-1.43] for cardiovascular death). In pSBP-unadjusted studies, increased cSBP was also associated with higher risk of all-cause mortality and stroke, but not in the pSBP-adjusted studies. Both cSBP and pSBP were similarly significantly associated with composite cardiovascular endpoints in models containing them separately and simultaneously. cSBP was significantly associated with cardiovascular events, independently of pSBP. Central or peripheral SBP could supplement cardiovascular risk assessment besides each other.

Background: Hypertension, a key modifiable risk factor for cardiovascular disease, is more prevalent among Black and low-income individuals. To address this health disparity, leveraging safety-net emergency departments for scalable mobile health (mHealth) interventions, specifically using text messaging for self-measured blood pressure (SMBP) monitoring, presents a promising strategy. This study investigates patterns of engagement, associated factors, and the impact of engagement on lowering blood pressure (BP) in an underserved population. Objective: We aimed to identify patterns of engagement with prompted SMBP monitoring with feedback, factors associated with engagement, and the association of engagement with lowered BP. Methods: This is a secondary analysis of data from Reach Out, an mHealth, factorial trial among 488 hypertensive patients recruited from a safety-net emergency department in Flint, Michigan. Reach Out participants were randomized to weekly or daily text message prompts to measure their BP and text in their responses. Engagement was defined as a BP response to the prompt. The k-means clustering algorithm and visualization were used to determine the pattern of SMBP engagement by SMBP prompt frequency-weekly or daily. BP was remotely measured at 12 months. For each prompt frequency group, logistic regression models were used to assess the univariate association of demographics, access to care, and comorbidities with high engagement. We then used linear mixed-effects models to explore the association between engagement and systolic BP at 12 months, estimated using average marginal effects. Results: For both SMBP prompt groups, the optimal number of engagement clusters was 2, which we defined as high and low engagement. Of the 241 weekly participants, 189 (78.4%) were low (response rate: mean 20%, SD 23.4) engagers, and 52 (21.6%) were high (response rate: mean 86%, SD 14.7) engagers. Of the 247 daily participants, 221 (89.5%) were low engagers (response rate: mean 9%, SD 12.2), and 26 (10.5%) were high (response rate: mean 67%, SD 8.7) engagers. Among weekly participants, those who were older (>65 years of age), attended some college (vs no college), married or lived with someone, had Medicare (vs Medicaid), were under the care of a primary care doctor, and took antihypertensive medication in the last 6 months had higher odds of high engagement. Participants who lacked transportation to appointments had lower odds of high engagement. In both prompt frequency groups, participants who were high engagers had a greater decline in BP compared to low engagers. Conclusions: Participants randomized to weekly SMBP monitoring prompts responded more frequently overall and were more likely to be classed as high engagers compared to participants who received daily prompts. High engagement was associated with a larger decrease in BP. New strategies to encourage engagement are needed for participants with lower access to care.

Knowledge of the status of real-world home blood pressure (BP) measurements is crucial for establishing policies promoting hypertension treatment through home BP monitoring. However, only a few studies have investigated the status of home BP measurements in real-world settings. This study investigated the practice of Korean patients in measuring BP at home. This study recruited participants aged ≥20 years who were taking antihypertensives and conducted a questionnaire-based survey on home BP measurements. Of 701 participants recruited between August 2018 and April 2020, 673 were included in the analysis. Of these, 359 (53.3%) possessed home BP measurement devices. The devices used by 184 (51.3%) participants were validated, 110 (30.6%) were nonvalidated, and 65 (18.1%) had an unknown validation status. Only 18 patients (5.0%) with home BP devices were aware of the validation tests for home BP measurement devices. Of the 673 participants, 278 (41.3%) measured BP at home (77.4% of the patients owned home BP measurement devices). Among them, at least 74 (26.6%) performed proper measurements (at least once a month, at least twice a day or twice at a time, after at least 1 minute of rest, with at least a 1-min interval between each measurement, and 30 min after drinking coffee, exercising, or smoking). In conclusion, our community-based survey in the nonpresentive Korean population revealed a low rate of home BP measurement, a high rate of using nonvalidated devices, and a high rate of inappropriate measurements, suggesting that more efforts toward patient education regarding home BP measurements are needed.

BACKGROUND: A limited number of studies investigated the association between blood pressure variability (BPV) and cognitive impairment in patients with hypertension. This study aimed to identify the longitudinal association between BPV and cognitive decline and the role of blood pressure (BP) control in this association. METHODS AND RESULTS: Participants with hypertension from the HRS (Health and Retirement Study), the ELSA (English Longitudinal Study of Ageing), and the CHARLS (China Health and Retirement Longitudinal Study) were included. Variation independent of the mean (VIM) was adopted to measure BPV. Cognitive function was measured by standard questionnaires, and a standardized Z score was calculated. Linear mixed-model and restricted cubic splines were adopted to explore the association between BPV and cognitive decline. The study included 4853, 1616, and 1432 eligible patients with hypertension from the HRS, ELSA, and CHARLS, respectively. After adjusting for covariates, per-SD increment of VIM of BP was significantly associated with global cognitive function decline in Z scores in both systolic BP (pooled ß, -0.045 [95% CI, -0.065 to -0.029]) and diastolic BP (pooled ß, -0.022 [95% CI, -0.040 to -0.004]) among hypertensive patients. Similar inverse associations were observed in patients with hypertension taking antihypertensive drugs and in patients with hypertension with well-controlled BP. CONCLUSIONS: High BPV was independently associated with a faster cognitive decline among patients with hypertension, even those with antihypertensive medications or well-controlled BP. Further studies are needed to confirm our results and determine whether reducing BPV can prevent or delay cognitive decline.

Community treatment of hypertension in sub-Saharan Africa is hampered by gaps at several stages of the care cascade. We compared blood pressure (BP) levels (systolic, diastolic and pulse pressures) in four groups of participants by hypertension and treatment status. We conducted a nationally representative survey of adults 35 years and older using a multistage sampling strategy based on the 2013 Gambia Population and Housing Census. The BP measurements were taken in triplicate 5 min apart, and the average of the last two measurements was used for analysis. Systolic and diastolic BP levels and pulse pressure were compared by hypertension status using mean and 95% confidence intervals (CI). 53.1% of the sample were normotensive with mean systolic BP (SBP) of 119.2 mmHg (95% CI, 118.7-119.6) and diastolic BP (DBP) of 78.1 mmHg (77.8-78.3). Among individuals with hypertension, mean SBP was 148.7 mmHg (147.7-149.7) among those unaware of their hypertension, 152.2 mmHg (151.0-153.5) among treated individuals and was highest in untreated individuals at 159.3 mmHg (157.3-161.2). The findings were similar for DBP levels, being 93.9 mmHg (93.4-94.4) among the unaware, 95.1 mmHg (94.4-95.8) among the treated and highest at 99.1 mmHg (98.1-100.2) in untreated participants. SBP and DBP were higher in men, and SBP was as expected higher in those aged ≥55 years. BP level was similar in urban and rural areas. Our data shows high BP levels among participants with hypertension including those receiving treatment. Efforts to reduce the health burden of hypertension will require inputs at all levels of the care cascade.

Time in target range (TTR) and blood pressure variability (BPV) of systolic blood pressure (SBP) are independent risk factors for major adverse cardiovascular events (MACE) and all-cause mortality in hypertensive patients. However, the association of the combination of low TTR and high BPV of SBP with the risk of MACE and all-cause mortality is unclear. This study sought to investigate the combined effect of the TTR and BPV on the risk of MACE and all-cause mortality in patients with hypertension. A total of 11 496 hypertensive patients from the Kailuan cohort study were included in our study. All participants were divided into four groups according to their TTR and BPV levels. Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) and 95% confidence interval (CI) for incident MACE and all-cause mortality. During a median follow-up of 5.64 years, 839 MACEs (included 99 cases of myocardial infarction, 591 cases of stroke, and 191 cases of heart failure) and 621 deaths occurred. Compared with the high-TTR and low-BPV group, the HRs (95% CI) of MACE and all-cause mortality were 1.309 (1.025-1.671) and 1.842 (1.373-2.473) for the high-TTR and high-BPV group, 1.692 (1.347-2.125) and 1.731 (1.298-2.309) for the low-TTR & low-BPV group, 2.132 (1.728-2.629) and 2.247 (1.722-2.932) for the low-TTR & high-BPV group. Our study suggests that the combination of low TTR and high BPV of SBP was associated with a higher risk of MACE and all-cause mortality in patients with hypertension.

BACKGROUND: Atrial fibrillation (AF) is often asymptomatic and undiagnosed. As AF and hypertension often coexist, opportunistic AF detection during routine automated blood pressure (BP) measurement appears to be an attractive screening method. METHODS: A systematic literature search was conducted to identify studies assessing the diagnostic test accuracy of office, home, or 24-hour ambulatory BP measuring devices with AF detection algorithms versus reference electrocardiography. Analyses were performed per participant (AF status based on several BP readings; most office/home devices) or per reading (AF status based on individual readings; all ambulatory devices). A meta-analysis stratified by device type (office/home/ambulatory) was conducted to calculate pooled measures of diagnostic accuracy. Sensitivity/meta-regression analyses were also performed. RESULTS: Among 3096 records initially retrieved, 23 diagnostic test accuracy studies were included. Data derived from 11â 093 individuals (weighted age 69 years, males 56%, hypertensives 79%, diabetics 24%, and AF prevalence 17%) indicated a pooled sensitivity 0.97 (95% CI, 0.92-0.99), specificity 0.93 (95% CI, 0.90-0.95), and accuracy 0.93 (95% CI, 0.89-0.95), with generally consistent results using office, home, or ambulatory BP devices (slightly lower specificity with the latter). The positive and negative predictive values were 0.70 (95% CI, 0.60-0.80) and 0.99 (95% CI, 0.98-1.00), respectively. Sensitivity analyses indicated lower specificity in studies implementing reading versus participant analyses. Most studies presented a low risk of bias and minor applicability concerns. CONCLUSIONS: There is considerable and consistent evidence suggesting high diagnostic accuracy of AF detection algorithms implemented in automated BP monitors during routine BP measurements in and out of the office. AF diagnosis requires verification (electrocardiography) before treatment is administered.

BACKGROUND: It is unknown whether maintaining normal blood pressure (BP) from middle to older age is associated with improved health outcomes. METHODS: We estimated the proportion of Atherosclerosis Risk in Communities study participants who maintained normal BP from 1987 to 1989 (visit 1) through 1996 to 1998 and 2011 to 2013 (over 4 and 5 visits, respectively). Normal BP was defined as systolic BP <120 mmâ Hg and diastolic BP <80 mmâ Hg, without antihypertensive medication. We estimated the risk of cardiovascular disease, dementia, and poor physical functioning after visit 5. In exploratory analyses, we examined participant characteristics associated with maintaining normal BP. RESULTS: Among 2699 participants with normal BP at baseline (mean age 51.3 years), 47.1% and 15.0% maintained normal BP through visits 4 and 5, respectively. The hazard ratios comparing participants who maintained normal BP through visit 4 but not visit 5 and through visit 5 versus those who did not maintain normal BP through visit 4 were 0.80 (95% CI, 0.63-1.03) and 0.60 (95% CI, 0.42-0.86), respectively, for cardiovascular disease, and 0.85 (95% CI, 0.71-1.01) and 0.69 (95% CI, 0.54-0.90), respectively, for poor physical functioning. Maintaining normal BP through visit 5 was more common among participants with normal body mass index versus obesity at visit 1, those with normal body mass index at visits 1 and 5, and those with overweight at visit 1 and overweight or normal body mass index at visit 5, compared with those with obesity at visits 1 and 5. CONCLUSIONS: Maintaining normal BP was associated with a lower risk of cardiovascular disease and poor physical functioning.

BACKGROUND: Hypertensive disorders of pregnancy (HDP), including gestational hypertension, preeclampsia, and eclampsia, are risk factors for cardiovascular (CV) disease. Guidelines recommend that women with HDP be screened for the development of hypertension (HTN) within 6-12 months postpartum. However, the extent to which this early blood pressure (BP) screening is being performed and the impact on detection of CV risk factors is unknown. METHODS: Women with HDP and without pre-existing hypertension (HTN) who had at least 6 months of clinical follow-up were categorized by postpartum BP screening status: early BP screen (6-12 months after delivery) or late BP screen (≥12 months after delivery). Multivariable logistic regression identified factors associated with early screening. Multivariable Cox proportional hazards modeling examined the association between early screening and detection of incident CV risk factors: HTN, prediabetes, diabetes mellitus type 2, or hyperlipidemia. RESULTS: Among 4194 women with HDP, 1172 (28%) received early BP screening. Older age, pre-existing hyperlipidemia, diabetes, sickle cell disease, hypothyroidism, gestational diabetes, and delivery during or after 2014 were independently associated with early BP screening, whereas Hispanic ethnicity was associated with late BP screening. Early BP screening was most commonly performed at a primary care visit. After a median follow-up of 3.7 years, 1012 (24%) women had at least 1 new risk factor detected. Even after adjustment for baseline risk, women receiving early BP screening had a significantly higher rate of incident CV risk factor detection than women receiving late BP screening (56% vs 28%; adj. HR 2.70, 95%CI: 2.33-3.23, P < .001). CONCLUSIONS: Early postpartum BP screening was performed in a minority of women with HDP, but was associated with greater detection of CV risk factors. More intensive postpartum CV screening and targeted interventions are needed to optimize CV health in this high-risk population of women with HDP.

The prevalence of isolated systolic hypertension (ISH) has doubled between 2002-2005 and 2014 among the oldest-old population in China. However, the prevalence and characteristics of ISH among the oldest-old population in southwestern China remain less known. This study aimed to investigate the prevalence of ISH among the oldest-old population in Chengdu and identify associated factors to provide valuable information for disease etiology and prevention. We recruited 1,312 participants aged over 80 years by using a stratified cluster sampling method between September 2015 and June 2016, from three districts (Jinjiang, Qingyang, and Longquanyi) of Chengdu, the largest city of southwest China. A structured questionnaire, anthropometric data, and blood pressure were collected according to the standard method. Blood pressure was measured three times by using a standardized mercury sphygmomanometer after a 10-minute seated rest. Of 1312 participants, 53.0% (n = 695) had ISH. The prevalence of ISH in men and women was 54.7% and 51.3%, respectively, with no significant sex difference (P = .222). The prevalence of ISH increased with advanced age in men (P for trend = 0.029), 52.5% for the 80-84 years group, 55.2% for the 85-89 years group, and 70.4% for the 90-98 years group, respectively. Multivariable logistic regression analyses found that drinking (OR = 1.85, 95%CI = 1.26-2.71), being overweight (OR = 1.88, 95%CI = 1.19-2.96), and having a higher heart rate (OR = 0.66, 95%CI = 0.51-0.86) were associated with ISH. Stratified by sex, these three factors remained significant in men. Our work highlights that the burden of ISH is substantial among the oldest-old population in southwestern China.

Postexercise blood pressure (BP) may be a better predictor of cardiovascular risk than office BP, but there is a lack of data supporting this claim. We hypothesized that postexercise BP may be an important prognostic marker. Our aim was to evaluate the association of postexercise BP with major adverse cardiovascular events (MACE) and all-cause mortality. A total of 2581 participants (median age, 46 years; 55.9% women) from the Coronary Artery Risk Development in Young Adults study at year 20 (2005-2006) who underwent a graded exercise treadmill test using a modified Balke graded protocol were included. Postexercise BP was measured at baseline. Cox models were used to estimate the associations of postexercise BP with MACE and all-cause mortality. Participants were followed up until December 31, 2021. In the entire population, postexercise systolic BP showed no significant association with MACE or all-cause mortality, while postexercise diastolic BP was associated with MACE (hazard ratios [HR], 1.27 [95% CI, 1.06-1.52], per 10 mmHg increase) and all-cause mortality (HR, 1.26 [95% CI, 1.05-1.51], per 10 mmHg increase). In the normal BP group, postexercise systolic BP was not significantly associated with MACE or all-cause mortality, and postexercise diastolic BP was strongly associated with MACE (HR, 1.57 [95% CI, 1.18-2.09], per 10 mmHg increase). In this population-based cohort study, postexercise diastolic BP was significantly associated with the risk of MACE and all-cause mortality. Among individuals with normal BP, postexercise diastolic BP could identify those at a higher risk of cardiovascular events.

This study evaluated an oscillometric device (OD), Microlife WatchBP Office AFIB, and a hybrid manual auscultatory device (AD), Greenlight 300TM, to determine a suitable blood pressure (BP) measurement device for the Korea National Health and Nutrition Examination Survey in a mercury-free context. Adhering to the 2018 Universal Standard's suggested consensus, the study involved 800 subjects (mean age 51.2 ± 17.5 years; 44.3% male), who underwent triplicate BP measurements following 5 min of rest in a randomized order (OD-first: 398 participants; AD-first: 402 participants). BP difference was calculated as OD value minus AD value, with results stratified by measurement sequence. The overall BP difference and tolerable error probability were -1.1 ± 6.5/-2.6 ± 4.9 mmHg and 89.2%/92.5% for systolic/diastolic BP (SBP/DBP), respectively. Lin's concordance correlation coefficient was 0.907/0.844 for SBP/DBP (OD-first/AD-first: 0.925/0.892 for SBP, 0.842/0.845 for DBP). The overall agreement for hypertension (BP ≥ 140 and/or 90 mmHg) was 0.71 (p < 0.0001), and the OD underestimated the overall hypertension prevalence by 5.1%. Analysis of the AD-first data revealed a lower level of agreement compared to the OD-first data; however, the observed blood pressure difference adhered to Criterion 1 of the 2018 Universal Standard. Microlife met the Criterion 1 of 2018 Universal Standard but underestimated the prevalence of hypertension. The BP discrepancy increased with higher BP levels, male sex, and smaller AC. With increasing age, the discrepancy decreased for SBP and increased for DBP.

In patients with hypertension and pre-frailty or frailty, the influence of systolic (SBP) and diastolic blood pressure (DBP) time in target range (TTR) on clinical outcomes is unclear. Thus, we conducted a post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT). Classifying 4208 participants into frail and non-frail groups using a frailty index, the study calculated blood pressure time in target range (BP-TTR) for the first three months using the Rosendaal method. The primary endpoint included a composite of nonfatal myocardial infarction (MI), acute coronary syndromes, stroke, acute decompensated heart failure (ADHF), and cardiovascular death. Relationships between BP-TTR and outcomes were analyzed using Kaplan-Meier curves, Cox models, and restricted cubic spline curves, with subgroup analysis for further insights. In a median follow-up of 3.17 years, primary outcomes occurred in 6.7% of participants. Kaplan-Meier analysis showed that a lower systolic blood pressure time in target range (SBP-TTR) (0%-25%) correlated with an increased cumulative incidence of the primary outcome (p < .001), nonfatal MI (P = .021), stroke (P = .004), and cardiovascular death (P = .002). A higher SBP-TTR (75%-<100%) was linked to a reduced risk of these outcomes. The restricted cubic spline (RCS) curve revealed a linear association between SBP-TTR and the primary outcome (non-linear P = .704). Similar patterns were observed for diastolic blood pressure time in target range (DBP-TTR). Subgroup analysis showed that the protective effect of higher SBP-TTR was less pronounced at low DBP-TTR levels (P for interaction = .023). In conclusion, this study highlights the importance of maintaining BP within the target range to mitigate cardiovascular risks in this population.

BACKGROUND: Hypertensive disorders of pregnancy affect approximately 15% of pregnancies in the United States and are a leading cause of postpartum readmissions. Morbidity due to hypertension may be higher in the first several weeks postpartum. The ability to monitor blood pressure and intervene in the postpartum period is critical to reducing morbidity and mortality. LOCAL PROBLEM: At WellSpan Health, hypertensive disorders were increasing and a leading cause of severe maternal morbidity and readmission. INTERVENTIONS: A remote blood pressure monitoring app called BabyScripts™ myBloodPressure was implemented in September 2020. Prior to discharge postpartum, all patients with a diagnosis of a hypertensive disorder of pregnancy were given an automatic blood pressure cuff and instructions on how to monitor and track their blood pressure daily in the app. RESULTS: A total of 1,260 patients were enrolled in the BabyScripts™ myBloodPressure module between September 2020 and July 2022 across five maternity hospitals. Of those enrolled 74% ( n = 938) entered seven or more blood pressures, and of those who entered at least one blood pressure 9% ( n = 107) entered at least one critical range blood pressure ( ≥ 150 mmHg systolic and or ≥ 100 mmHg diastolic). CONCLUSION: Most women enrolled in the app were highly engaged and entered seven or more readings. Patients with critical blood pressures were identified; thus, the program has the potential to identify those at risk of severe complications. Barriers should be removed, and remote patient monitoring considered as a solution to improve postpartum assessment in patients with hypertensive disorders of pregnancy.

BACKGROUND: Hypertensive disorders of pregnancy are one of the leading causes of maternal morbidity and mortality worldwide. Management of these conditions can pose many clinical dilemmas and can be particularly challenging during the immediate postpartum period. Models for predicting and managing postpartum hypertension are necessary to help address this clinical challenge. OBJECTIVE: This study aimed to evaluate predictive models of blood pressure spikes in the postpartum period and to investigate clinical management strategies to optimize care. STUDY DESIGN: This was a retrospective cohort study of postpartum women who participated in remote blood pressure monitoring. A postpartum blood pressure spike was defined as a blood pressure measurement of ≥140/90 mm Hg while on an antihypertensive medication and a blood pressure measurement of ≥150/100 mm Hg if not on an antihypertensive medication. We identified 3 risk level patient clusters (low, medium, and high) when predicting patient risk for a blood pressure spike on postpartum days 3 to 7. The variables used in defining these clusters were peak systolic blood pressure before discharge, body mass index, patient systolic blood pressure per trimester, heart rate, gestational age, maternal age, chronic hypertension, and gestational hypertension. For each risk cluster, we focused on 2 treatments, namely (1) postpartum length of stay (<3 days or ≥3 days) and (2) discharge with or without blood pressure medications. We evaluated the effectiveness of the treatments in different subgroups of patients by estimating the conditional average treatment effect values in each cluster using a causal forest. Moreover, for all patients, we considered discharge with medication policies depending on different discharge blood pressure thresholds. We used a doubly robust policy evaluation method to compare the effectiveness of the policies. RESULTS: A total of 413 patients were included, and among those, 267 (64.6%) had a postpartum blood pressure spike. The treatments for patients at medium and high risk were considered beneficial. The 95% confidence intervals for constant marginal average treatment effect for antihypertensive use at discharge were -3.482 to 4.840 andâ¯-â¯5.539 to 4.315, respectively; and for a longer stay they were -5.544 to 3.866 and -7.200 to 4.302, respectively. For patients at low risk, the treatments were not critical in preventing a blood pressure spike with 95% confidence intervals for constant marginal average treatment effect of 1.074 to 15.784 and -2.913 to 9.021 for the different treatments. We considered the option to discharge patients with antihypertensive use at different blood pressure thresholds, namely (1) ≥130 mm Hg and/or ≥80 mm Hg, (2) ≥140 mm Hg and/or ≥90 mm Hg, (3) ≥150 mm Hg and/or ≥ 100 mm Hg, or (4) ≥160 mm Hg and/or ≥ 110 mm Hg. We found that policy (2) was the best option with P<.05. CONCLUSION: We identified 3 possible strategies to prevent outpatient blood pressure spikes during the postpartum period, namely (1) medium- and high-risk patients should be considered for a longer postpartum hospital stay or should participate in daily home monitoring, (2) medium- and high-risk patients should be prescribed antihypertensives at discharge, and (3) antihypertensive treatment should be prescribed if patients are discharged with a blood pressure of ≥140/90 mm Hg.

BACKGROUND: Hypertension and diabetes mellitus (DM) are major causes of natural death in South Africa (SA). Underdiagnosis of these treatable diseases would hamper efforts to improve their management and hence reduce morbidity and mortality. OBJECTIVES: To assess the level of underdiagnosis of hypertension and DM in SA. METHODS: Data from adult participants (≥15 years) in the 2016 South African Demographic and Health Survey, which draws a nationally representative sample of the population, was used. Using these data, the prevalence of hypertension and DM was assessed at the time of the study using objective criteria (hypertension: systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg; DM: glycated haemoglobin (HbA1c) ≥6.5%), and disease prevalence based on participant recall of having ever received a diagnosis of hypertension or DM from a healthcare professional. The difference between the objectively measured prevalence of the diseases and the prevalence based on recall was used to assess the level of underdiagnosis. RESULTS: Of 10 336 adult participants who answered the question on the recall of a diagnosis, 8 092 had their blood pressure measured, and 6 740 had HbA1c assessed. The prevalence of hypertension based on recall was 18.9% (95% confidence interval (CI) 17.7 - 20.1), while the prevalence using blood pressure measurements was 37.1% (95% CI 35.3 - 38.9). Therefore, 49% of cases of hypertension are likely to be undiagnosed (~7.1 million people). The prevalence of DM based on recall was 4.5% (95% CI 3.9 - 5.1), and 11.4% (95% CI 10.4 - 12.4) based on HbA1c values. Therefore, 61% of cases of DM are likely to be undiagnosed (~2.7 million people). CONCLUSIONS: There is significant underdiagnosis of hypertension and DM in SA. The underdiagnosis of these two treatable conditions, which have high morbidity and mortality, has major population health implications.

BACKGROUND Hyperhomocysteinemia (HHcy) and metabolic syndrome (MS) are established cardiovascular risk factors of stroke and are frequently associated with hypertension. However, studies on the association between HHcy combined with MS and stroke risk in hypertensive patients were absent. MATERIAL AND METHODS In 14 059 selected participants with elevated blood pressure, we assessed the prevalence of the MS and stroke. We defined HHcy as plasma total homocysteine >15 µmol/L. MS was defined according to the Chinese Diabetes Society (CDS) criterion. Multivariable analysis was used to examine the association of HHcy or (and) MS with stroke risk in different models. RESULTS The prevalence rates of HHcy and MS were 49.96% and 42.21%, respectively. Patients with stroke had higher plasma total homocysteine levels and a higher prevalence of MS (P<0.001). Multivariable analyses indicated that HHcy and MS are independently associated with higher prevalence of stroke (adjusted-odds ratio (OR): 1.36, 95% CI 1.17 to 1.58, P<0.001; adjusted-OR: 1.68, 95% CI 1.44 to 1.96, P<0.001, respectively). Those with combined HHcy and MS had higher odds of stroke than those with isolated HHcy or MS (adjusted-OR: 1.78, 95% CI 1.47 to 2.15, P<0.001; adjusted-OR: 1.39, 95% CI 1.13 to 1.70, P=0.002, respectively). CONCLUSIONS HHcy combined with MS was associated with higher prevalence of stroke in Chinese adults with elevated blood pressure.
