Home blood pressure–guided antihypertensive therapy in chronic kidney disease: more data are needed

In the era of newly introduced hypertension guidelines recommending lower blood pressure (BP) targets for drug-treated hypertensives, the necessity for optimized management of hypertension becomes even more urgent. The concept of home BP–guided antihypertensive therapy is for long suggested as a simple and feasible approach to improve BP control rates and optimize the management of hypertension. Home BP–guided antihypertensive therapy is particularly applicable to hypertensives with chronic kidney disease (CKD) for several reasons including the following: (1) difficult-to-control BP and high BP variability in the CKD setting; (2) poor accuracy of office BP in determining hypertension control status and detecting “white-coat” and “masked” hypertension; (3) poor value of routine office BP recordings in predicting the longitudinal progression of target-organ damage; and (4) superiority of home BP over office BP recordings in prognosticating the risk of incident end-stage renal disease or death. The concept of home BP–guided antihypertensive therapy is even more relevant for those on hemodialysis, given the high intradialytic and interdialytic BP variability and poor value of conventional peridialytic BP recordings in estimating the actual BP load recorded outside of dialysis with the use of home or ambulatory BP monitoring. Randomized trials comparing home BP–guided antihypertensive therapy versus usual care are warranted to prove the feasibility and effectiveness of this therapeutic approach and convince clinicians for using home BP monitoring as the standard of care when managing hypertension, particularly in people with CKD or end-stage renal disease.     

Determinants of Self-Measured Pulse Rate Profile in Medicated Hypertensives: The Jichi Morning Surge–1 (JMS-1) Study

Background. Recently, it was reported that high pulse rate (PR), which was measured using by self-measured blood pressure (BP) monitoring at home, was associated with cardiovascular risk. However, the predictor of high PR at home in treated hypertensives is unknown. In this study, we studied the predictor of high PR and evaluated pulse rate variability (PRV). Methods. In the JMS-1 study, 611 hypertensive outpatients were recruited. Self-measured BP monitoring was conducted consecutively twice in the morning and evening for three days. PR analysis was conducted using the average of these two measurements for three days (six readings in total). We defined home PR as the mean of these six readings. Home PRV was defined as the standard deviation of these six readings. Results. Multivariate linear regression analysis demonstrated that current smoking (β = 0.12, p = 0.002), diabetes (β = 0.16, p < 0.001), lack of angiotensin-converting enzyme (ACE) inhibitor use (β = 0.10, p = 0.008), decreased brain-type natriuretic peptide (BNP; β = 0.17, p < 0.001), and elevated home diastolic blood pressure (β = 0.14, p = 0.009) were determinants of high PR. Determinants of decreased home PRV were female gender (β = 0.10, p < 0.03) and increased hemoglobin A1c (HbA1c; β = 0.15, p < 0.001). When we divided the patients into four groups according to home PR and its variability, hypertensives whose home PR was high and variability was low were found to have high HbA1c (ANOVA, p > 0.05). Conclusions. Smoking habit, diabetes, lack of ACE inhibitor use, and low BNP value were determinants of home PR, and female gender and higher HbA1c were significantly associated with its low variability. Home PR and its variability may be useful for detecting high-risk hypertensive patients, particularly with autonomic neuropathy.     

Comparison of day‐to‐day blood pressure variability in hypertensive patients with type 2 diabetes mellitus to those without diabetes: Asia BP@Home Study

Blood pressure variability (BPV) has been shown to be independently associated with cardiovascular (CV) mortality and morbidity. Patients with type 2 diabetes mellitus (T2DM) have also been shown to have increased BPV. We aimed to compare BPV in hypertensive patients with diabetes with those without diabetes. A total of 1443 hypertensive patients measured their blood pressure (BP) twice in the morning and twice before bed at home for a week. Demographic data, history of T2DM, and anti‐hypertensive use were captured. Clinic BP was measured twice in the clinic. Control of BP was defined as clinic systolic BP (SBP) <140 mm Hg and home SBP < 135 mm Hg. BPV was based on home SBP measurements. A total of 362(25.1%) hypertensives had diabetes and 47.4% were male. Mean age was 62.3 ± 12.1 years. There was no difference in the mean clinic SBP in both groups (139.9 mm Hg vs 138.4 mm Hg P = .188). However, the mean morning home SBP was significantly higher and control rate lower in hypertensives with diabetes than those without (132.3 ± 15 mm Hg vs 129.7 ± 14.4 mm Hg P = .005, 39.4% vs 47.6% P = .007), respectively. Masked uncontrolled morning hypertension was higher in those with diabetes versus those without (12.8% vs 8.4%, respectively). There was no statistically significant difference in BPV between those with and without diabetes. In summary, clinic SBP was similar in hypertensives with or without diabetes. However, control of BP based on both clinic and home SBP thresholds was poorer in hypertensives with diabetes compared to those without. Masked uncontrolled morning hypertension was higher in those with diabetes than those without. There was no difference in BPV between the two groups.     

Central blood pressure for the management of hypertension: Is it a practical clinical tool in current practice?

Since noninvasive central blood pressure (BP) measuring devices are readily available, central BP has gained growing attention regarding its clinical application in the management of hypertension. The disagreement between central and peripheral BP has long been recognized. Some previous studies showed that noninvasive central BP may be better than the conventional brachial BP in association with target organ damages and long‐term cardiovascular outcomes. Recent studies further suggest that the central BP strategy for confirming a diagnosis of hypertension may be more cost‐effective than the conventional strategy, and guidance of hypertension management with central BP may result in less use of medications to achieve BP control. Despite the use of central BP being promising, more randomized controlled studies comparing central BP‐guided therapeutic strategies with conventional care for cardiovascular events reduction are required because noninvasive central and brachial BP measures are conveniently available. In this brief review, the rationale supporting the utility of central BP in clinical practice and relating challenges are summarized.     

Balance performance, aging and falling: a comparative study based on a Turkish sample

The effects of aging and gender on balance performance (BP) among ambulatory adults were investigated in the current work. If there was a relation between the BP and a history of falling, this was also detected. Two hundred and forty ambulatory subjects were divided into two groups depending on their age: (1) 125 middle-aged subjects (50–64 years); (2) 115 elderly subjects (65–75). The functional reach (FR) test, the timed up and go (TUG) test, the sit to stand (STS) test and the step test (ST) were used to evaluate the BP. The fall rate (1–2 in the last year) was 8% for the middle-aged group and was 13.9% for the elderly group. Middle-aged adults had better scores on all tests in comparison to the elderly people. There have been differences found between genders regarding the BP in both groups, except the FR scores in the middle-aged group. The FR distance of the faller subjects was rather low in comparison to non-faller elderly subjects. However, there were no significant differences between the faller and non-faller subjects in both groups regarding other tests’ scores. The results of this study indicate that aging affects the BP year by year. The information in this paper can provide normative data to be used as a comparison to clinically obtained information.     

Is the blood pressure the same in both arms?

It is generally believed that there are blood pressure differences between the right and left arms, but most of the validation studies have used nonsimultaneous measurements. It is important to know whether there is a difference, as methodological comparisons are often made using a different technique on each arm. We have measured the blood pressure simultaneously in both arms in 91 patients, using two observers and two cuffs to provide eight measurements in a fully balanced design. The mean difference in blood pressure between the arms (left/right) was -1.3 (SE 0.4)/1.1 (SE 0.3) mmHg. Mean differences of the same magnitude were found between the two observers, and between the cuffs. Thus, no systematic difference of any consequence was found, although individual patients had mean between-arm differences in blood pressure of up to 10 mmHg. These results suggest that no significant bias is introduced in methodological comparisons that use both arms.     

Case management and risk of nursing home admission for older adults in home care: results of the AgeD in HOme Care Study

OBJECTIVES: To explore the relationship between a case management approach and the risk of institutionalization in a large European population of frail, old people in home care. DESIGN: Retrospective cohort study. SETTING: Eleven European countries. PARTICIPANTS: Three thousand two hundred ninety-two older adults receiving home care (mean age 82.3+/-7.3). MEASUREMENTS: Data on nursing home admission were collected every 6 months for 1 year. RESULTS: One thousand one hundred eighty-four (36%) persons received a home care program based on case management, and 2,108 (64%) received a traditional care approach (no case manager). During the 1-year follow-up, 81 of 1,184 clients (6.8%) in the case management group and 274 of 2,108 (13%) in the traditional care group were admitted to a nursing home (P<.001). After adjusting for potential confounders, the risk of nursing home admission was significantly lower for participants in the case management group than for those in a traditional care model (adjusted odds ratio=0.56, 95% confidence interval=0.43-0.63). CONCLUSION: Home care services based on a case management approach reduce risk of institutionalization and likely lower costs.     

The Future of the Home Care Workforce: Training and Supporting Aides as Members of Home‐Based Care Teams

Home health, home care, and personal care aides provide most of the paid hands‐on care delivered to seriously ill, functionally impaired individuals in their homes, assisted living, and other noninstitutional settings. This workforce delivers personal care, assistance with activities of daily living, and emotional support to their patients. They are often the eyes and ears of the health system, observing subtle changes in condition that can provide important information for clinical decision making and therapeutic intervention. Despite this fact, the growing number of team‐based home care initiatives have failed to incorporate this workforce into their programs. Barriers to inclusion of aides into teams include a basic lack of value and understanding on the part of clinical team members and society in general of the complex tasks that these caregivers perform, inadequate investments in training and education of this workforce to develop their knowledge and competencies, and variation in state delegation laws that limit the scope of practice and consequently the ability of aides to work effectively in teams and to advance in their careers. Building on the few programs that have successfully included aides as key members of home care teams, federal and state policymakers, educators, and health systems and providers should standardize competency‐based training requirements, expand nurse delegation consistently across states, and support evaluation, dissemination, and replication of successful programs.

Unobserved automated office BP is similar to other clinic BP measurements: A prospective randomized study

Results of the SPRINT study have been disputed, based on the assumption that unattended BP measurements do not correlate with usual BP measurements. In this study, the authors investigated the correlation of unattended SPRINT‐like measurements with other conventional measurements. All BP measurements were taken with the patient seated in a comfortable chair with the legs uncrossed and not speaking during the procedure. For the purpose of this study, sixty‐five patients, mostly male (93%), were recruited from our hypertension clinic and all were on antihypertensive medication (av 3.0 ± 1.1). Patients were at high cardiovascular risk with high rates of comorbidities, av age 68 ± 12 years, 49% with diabetes, 34% with mild CKD (CKD 1‐3, average eGFR 55.0 ± 13 mL/min/1.73 m²), and 20% with history of stable coronary artery disease. All BP measurements were similar with no statistically significant difference (one‐way ANOVA, P = 0.621). Compared to unattended SPRINT BP values (139.77 ± 19.22/75.42 ± 11.72 mm Hg), the clinic BP measurements were numerically slightly higher but with a NS P value (P = 0.163). Similarly, unattended BP measurements were similar to values taken by the clinic physician. In a smaller cohort of 11 patients, the authors compared unobserved vs observed SPRINT‐like BP measurements, and in 13 patients, the authors compared unobserved SPRINT‐like BP measurements to average home BP measurements (Table 3). There were no significant differences between any of the subgroups (one‐way ANOVA, P = 0.816 for systolic and P = 0.803 for diastolic). The authors conclude that unattended BP measurements taken (the SPRINT way) are similar to other conventional office blood pressure measurements.     

Terminal home care in the Netherlands: An overview

Beginning in the late 1980s, after a long period of declining interest in home care for the terminally ill, several projects and experiments were initiated in the Netherlands. This article describes this trend and provides background information on the Dutch health services, a definition of terminal home care, and statistical information about the different types of home care in the Netherlands. Findings from 3 recent studies of these projects and experiments are presented along with the guidelines for providing good terminal home care formulated by the Dutch Health Council in 1991.     

艾滋病自检的研究进展

艾滋病自检的形式包括自助采样送检和自测两种。虽然艾滋病自检的提出已有20多年的历史,但自检本身仍存在很大争议,一方面,艾滋病自检有利于保护检测者隐私,赋予人们自我管理感染艾滋病风险的权利,使得它在人群中有一定的需求;另一方面,自检又存在缺乏准确性、专业咨询和支持等问题,使得管理部门对放开自检心存顾虑。目前世界范围内,艾滋病自检基本处于研究阶段。中国对艾滋病自检研究很少,有必要加强相关研究,正确引导自检,扬长避短,使其为扩大艾滋病检测面服务。     

Effect of an in-home occupational and physical therapy intervention on reducing mortality in functionally vulnerable older people: preliminary findings

OBJECTIVES: To evaluate the effect of a multicomponent intervention on mortality and the role of control-oriented strategy use as the change mechanism. DESIGN: Two-group randomized design with survivorship followed for 14 months. Participants were randomized to intervention or a no-treatment control group. SETTING: Urban, community-living older people. PARTICIPANTS: Three hundred nineteen people aged 70 and older with functional difficulties. INTERVENTION: Occupational therapy and physical therapy sessions involving home modifications, problem solving, and training in energy conservation, safe performance, balance, muscle strength, and fall recovery techniques. MEASUREMENTS: Survival time was number of days between baseline interview and date of death or final interview if date unknown. Control-oriented strategy use was measured using eight items. RESULTS: Intervention participants exhibited a 1% rate of mortality, compared with a 10% rate for no-treatment control participants (P=.003, 95% confidence interval=2.4-15.04%). At baseline, those who subsequently died had more days hospitalized and lower control-oriented strategy use 6 months before study enrollment than survivors. No intervention participants with previous days hospitalized (n=31) died, whereas 21% of control group counterparts did (n=35; P=.001). Although intervention participants with low and high baseline control strategy use had lower mortality risk than control participants, mortality risk was lower for intervention participants with low strategy use at baseline (P=.007). CONCLUSION: An occupational and physical therapy intervention to ameliorate functional difficulties may reduce mortality risk in community-dwelling older people overall and benefit those most compromised. Instruction in control-oriented strategies may account for the intervention's protective effects on survivorship.     

A randomized trial of a multicomponent home intervention to reduce functional difficulties in older adults

OBJECTIVES: To test the efficacy of a multicomponent intervention to reduce functional difficulties, fear of falling, and home hazards and enhance self-efficacy and adaptive coping in older adults with chronic conditions. DESIGN: A prospective, two-group, randomized trial. Participants were randomized to a treatment group or no-treatment group. SETTING: Urban community-living older people. PARTICIPANTS: Three hundred nineteen community-living adults aged 70 and older who reported difficulty with one or more activities of daily living. INTERVENTION: Occupational and physical therapy sessions involving home modifications and training in their use; instruction in strategies of problem-solving, energy conservation, safe performance, and fall recovery techniques; and balance and muscle strength training. MEASUREMENTS: Outcome measures included self-rated functional difficulties with ambulation, instrumental activities of daily living, activities of daily living, fear of falling, confidence performing daily tasks, and use of adaptive strategies. Observations of home hazards were also conducted. RESULTS: At 6 months, intervention participants had less difficulty than controls with instrumental activities of daily living (P=.04, 95% confidence interval (CI)=-0.28-0.00) and activities of daily living (P=.03, 95% CI=-0.24 to -0.01), with largest reductions in bathing (P=.02, 95% CI=-0.52 to -0.06) and toileting (P=.049, 95% CI=-0.35-0.00). They also had greater self-efficacy (P=.03, 95% CI=0.02-0.27), less fear of falling (P=.001, 95% CI=0.26-0.96), fewer home hazards (P=.05, 95% CI=-3.06-0.00), and greater use of adaptive strategies (P=.009, 95% CI=0.03-0.22). Benefits were sustained at 12 months for most outcomes. CONCLUSION: A multicomponent intervention targeting modifiable environmental and behavioral factors results in life quality improvements in community-dwelling older people who had functional difficulties, with most benefits retained over a year.     

Office blood pressure measurement: A comprehensive review

The conventional auscultatory methods for measuring blood pressure have been used to screen, diagnose, and manage hypertension since long. However, these have been found to be prone to errors especially the white coat phenomena which cause falsely high blood pressure readings. The Mercury sphygmomanometer and the Aneroid variety are no longer recommended by WHO for varying reasons. The Oscillometric devices are now recommended with preference for the Automated Office Blood Pressure measurement device which was found to have readings nearest to the Awake Ambulatory Blood Pressure readings. The downside for this device is the cost barrier. The alternative is to use the simple oscillometric device, which is much cheaper, with the rest and isolation criteria of the SPRINT study. This too may be difficult due to space constraints and the post‐clinic blood measurement is a new concept worth further exploration.     

Factors enabling home death of the elderly in an institution specializing in home medical care: Analysis of apprehension of the bereaved family

Aim:   To determine the factors enabling home death despite caregiver apprehension about home medical care.
Methods:   This study was an anonymous mailed survey of bereaved family members (the caregiver) of patients who died in a home medical care setting provided by an institution specializing in home medical care in Japan (home death rate, ∼80%). We analyzed the relationships between caregiver apprehension about home medical care, overall satisfaction with home medical care and the place of death.
Results:   Higher caregiver apprehension about home medical care and lower overall satisfaction with home medical care were significantly associated with dying in a hospital. In addition, the home death group with apprehension about home medical care significantly rated higher overall satisfaction with home medical care than the hospital death group. Meanwhile, there was no difference in the overall satisfaction with home medical care between those with or without apprehension about home medical care in the home death group. Factors influencing overall satisfaction with home medical care in the home death group with apprehension about home medical care were: (i) being free from pain or symptoms (partial regression coefficient: 0.83); and (ii) fulfilled medical care service system (partial regression coefficient: 0.40).
Conclusion:   These results suggest that caregiver satisfaction with home medical care is an essential factor to enable home death of the patient despite the caregiver apprehension about home medical care.
