Reducing Hypertension in a Poststroke Black and Hispanic Home Care Population: Results of a Pragmatic Randomized Controlled Trial

The short and long-term efficacy of nurse-led interventions for improving blood pressure control in people with hypertension in primary care settings: a systematic review and meta-analysis

BACKGROUND

Previous systematic reviews suggest that nurse-led interventions improve short-term blood pressure (BP) control for people with hypertension. However, the long-term effects, adverse events, and appropriate target BP level are unclear. This study aimed to evaluate the long-term efficacy and safety of nurse-led interventions.

METHODS

We conducted a systematic review and meta-analysis. We searched the Cochrane Central Register of Controlled Trials, PubMed, and CINAHL, as well as three Japanese article databases, as relevant randomized controlled trials from the oldest possible to March 2021. This search was conducted on 17 April 2021. We did an update search on 17 October 2023. We included studies on adults aged 18 years or older with hypertension. The treatments of interest were community-based nurse-led BP control interventions in addition to primary physician-provided care as usual. The comparator was usual care only. Primary outcomes were long-term achievement of BP control goals and serious adverse events (range: 27 weeks to 3 years). Secondary outcomes were short-term achievement of BP control goals and serious adverse events (range: 4 to 26 weeks), change of systolic and diastolic BP from baseline, medication adherence, incidence of hypertensive complications, and total mortality.

RESULTS

We included 35 studies. Nurse-led interventions improved long-term BP control (RR 1.10, 95%CI 1.03 to 1.18). However, no significant differences were found in the short-term effects of nurse-led intervention compared to usual care about BP targets. Little information on serious adverse events was available. There was no difference in mortality at both terms between the two groups. Establishing the appropriate target BP from the extant trials was impossible.

CONCLUSIONS

Nurse-led interventions may be more effective than usual care for achieving BP control at long-term follow-up. It is important to continue lifestyle modification for people with hypertension. We must pay attention to adverse events, and more studies examining appropriate BP targets are needed. Nurse-led care represents an important complement to primary physician-led usual care.

Disparities in Race and Ethnicity Reporting and Representation for Clinical Trials in Stroke: 2010 to 2020

BACKGROUND

Racial and ethnic minority groups are at a higher stroke risk and have poor poststroke outcomes. The aim of this study was to assess the frequency of race reporting and proportions of race and ethnicity representation in stroke-related clinical trials.

METHODS AND RESULTS

This is a descriptive study of stroke-related clinical trials completed between January 1, 2010 and December 31, 2020, and registered on ClinicalTrials.gov. Trials conducted in the United States, related to stroke and enrolling participants ≥18 years, were considered eligible. Trials were reviewed for availability of published results, data on race and ethnicity distribution, and trial characteristics. Overall, 60.1% of published trials reported race or ethnicity of participants, with a 2.6-fold increase in reporting between 2010 and 2020. White patients represented 65.0% of the participants, followed by 24.8% Black, 2.4% Asian or Pacific Islander, and <1% Native American and multiracial participants; 9.0% were of Hispanic ethnicity. These trends remained consistent throughout the study period, except in 2018, when a higher proportion of Black participants (53.1%) was enrolled compared with White participants (35.8%). Trials with the National Institutes of Health/federal funding had higher enrollment of Black (28.1%) and Hispanic (13.8%) participants compared with other funding sources. Behavioral intervention trials had the most diverse enrollment with equal enrollment of Black and White participants (41.1%) and 14.5% Hispanic participants.

CONCLUSIONS

Despite the increase in race and ethnicity reporting between 2010 and 2020, the representation of racial and ethnic minority groups remains low in stroke trials. Funding initiatives may influence diversity efforts in trial enrollment.

Interventions and contextual factors to improve retention in care for patients with hypertension in primary care: Hermeneutic systematic review

BACKGROUND

Regular engagement over time in hypertension care, or retention, is a crucial but understudied step in optimizing patient outcomes. This systematic review leverages a hermeneutic methodology to identify, evaluate, and quantify the effects of interventions and contextual factors for improving retention for patients with hypertension.

METHODS

We searched for articles that were published between 2000 and 2022 from multiple electronic databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and WHO International Trials Registry. We followed the latest version of the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline to report the findings for this review. We also synthesized the findings using a hermeneutic methodology for systematic reviews, which used an iterative process to review, integrate, analyze, and interpret evidence.

RESULTS

From 4686 screened titles and abstracts, 18 unique studies from 9 countries were identified, including 10 (56%) randomized controlled trials (RCTs), 3 (17%) cluster RCTs, and 5 (28%) non-RCT studies. The number of participants ranged from 76 to 1562. The overall mean age range was 41-67 years, and the proportion of female participants ranged from 0% to 100%. Most (n = 17, 94%) studies used non-physician personnel to implement the proposed interventions. Fourteen studies (78%) implemented multilevel combinations of interventions. Education and training, team-based care, consultation, and Short Message Service reminders were the most common interventions tested.

CONCLUSIONS

This review presents the most comprehensive findings on retention in hypertension care to date and fills the gaps in the literature, including the effectiveness of interventions, their components, and contextual factors. Adaptation of and implementing HIV care models, such differentiated service delivery, may be more effective and merit further study.

Transitional care of older ethnic minority patients: An integrative review

AIMS

To critically synthesize the empirical literature on practice in transitional care and how to meet the care needs of older ethnic minority populations who discharged from hospital to community.

DESIGN

An integrative literature review integrating empirical studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

DATA SOURCES

PubMed, Web of Science, PsycINFO, EBSCO (including CINAHL and MEDLINE) and Scopus were searched for papers published between 2012 and September 2022.

REVIEW METHODS

Full-text papers were screened against inclusion and exclusion criteria subsequent to screening titles and abstracts. All included papers were evaluated for methodological quality using the Critical Appraisal Skills Programme Checklists. After extracting findings, themes were created by critically examining and synthesizing of findings.

RESULTS

The search yielded a total of 1180 studies, 1153 after removing duplicates and 27 papers meeting the inclusion criteria and exclusion criteria were included in the review. The main findings were categorized into four themes: (i) intervention-related outcomes; (ii) unmet needs of older minority people; (iii) transitional care-related characteristics of older minority people and (iv) challenges for healthcare providers. Findings indicated that the transitional care experience of ethnic minority older populations differed from natives to some extent which revealed unmet needs addressing how to provide culturally appropriate transitional care for this population.

CONCLUSION

This review gave insight into facilitators in the transitional care of ethnic minority older adults. Future transitional care interventions should incorporate needs of ethnic minority population.

IMPACT

This review highlighted the defined gaps between existing transitional care programmes and transitional care needs of older ethnic minority. Increasing follow-up completion, evidence defining deeply of ethnic phenomenon in the transitional care process, developing interventions that meet transitional care needs and increasing healthcare providers' cultural competency were featured headlines. No Patient or Public Contribution.

Use of Community-Engaged Research Approaches in Clinical Interventions for Neurologic Disorders in the United States: A Scoping Review and Future Directions for Improving Health Equity Research

BACKGROUND AND OBJECTIVES

Evidence suggests a significant prevalence of race and ethnic disparities in the United States among people with neurologic conditions including stroke, Alzheimer disease and related dementia (ADRD), Parkinson disease (PD), epilepsy, spinal cord injury (SCI), and traumatic brain injury (TBI). Recent neurologic research has begun the paradigm shift from observational health disparities research to intervention research in an effort to narrow the disparities gap. There is an evidence base that suggests that community engagement is a necessary component of health equity. While the increase in disparities focused neurologic interventions is encouraging, it remains unclear whether and how community-engaged practices are integrated into intervention design and implementation. The purpose of this scoping review was to identify and synthesize intervention studies that have actively engaged with the community in the design and implementation of interventions to reduce disparities in neurologic conditions and to describe the common community engagement processes used.

METHODS

Two databases, PubMed and CINAHL, were searched to identify eligible empirical studies within the United States whose focus was on neurologic interventions addressing disparities and using community engagement practices.

RESULTS

We identified 392 disparity-focused interventions in stroke, ADRD, PD, epilepsy, SCI, and TBI, of which 53 studies incorporated community engagement practices: 32 stroke studies, 15 ADRD, 2 epilepsy studies, 2 PD studies, 1 SCI study, and 1 TBI study. Most of the interventions were designed as randomized controlled trials and were programmatic in nature. The interventions used a variety of community engagement practices: community partners (42%), culturally tailored materials and mobile health (40%), community health workers (32%), faith-based organizations and local businesses (28%), focus groups/health need assessments (25%), community advisory boards (19%), personnel recruited from the community/champions (19%), and caregiver/social support (15%).

DISCUSSION

Our scoping review reports that the proportion of neurologic intervention studies incorporating community engagement practices is limited and that the practices used within those studies are varied. The major practices used included collaboration with community partners and utilization of culturally tailored materials. We also found inconsistent reporting and dissemination of results from studies that implemented community engagement measures in their interventions. Future directions include involving the community in research early and continuously, building curricula that address challenges to community engagement, prioritizing the inclusion of community engagement reporting in peer-reviewed journals, and prioritizing and incentivizing research of subpopulations that experience disparities in neurologic conditions.

Self-reported gaps in care coordination and preventable adverse outcomes among older adults receiving home health care

BACKGROUND

Older adults see multiple outpatient providers and increasingly use home health care (HHC) services. Previous studies attempting to draw inferences about the association between HHC use and patient outcomes have been mixed. Whether HHC is associated with care coordination and how both influence outcomes are unknown. In addition, prior studies have not taken the patient perspective into account. We examined the association between receiving HHC and self-reported gaps in care coordination and separately, preventable adverse outcomes.

METHODS

The analysis for this cross-sectional study was conducted between October 2021 and June 2022, using data on 4296 Medicare beneficiaries from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who completed a survey on care coordination from 2017 to 2018. The associations between the receipt of HHC and two outcomes (a gap in care coordination, and separately, a preventable adverse event) were examined with Poisson models with robust standard errors. Potential confounders were accounted for through propensity score-based inverse probability weighting.

RESULTS

Among 4296 participants, 430 (10%) received HHC and they were older and had more comorbidities and ambulatory visits than those without HHC. HHC was not associated with differences in self-reported gaps in care coordination (33.3% HHC vs. 32.5% no-HHC, p = 0.70). HHC recipients reported more preventable drug-drug interactions (9.1% vs. 4.0%, p < 0.001) but not more preventable ED visits or hospital admissions. In IPW-adjusted models, HHC was not associated with gaps in care coordination (p = 0.60) but was associated with double the risk of a preventable adverse outcome (aRR 2.06; CI: 1.37, 3.10, p < 0.001).

CONCLUSIONS

HHC recipients were significantly more likely (than those without HHC) to report a potentially preventable adverse event (particularly a drug-drug interaction), suggesting an opportunity to improve patient safety by leveraging the observations of older adults receiving HHC.

Secondary Stroke Risk Reduction in Black Adults: a Systematic Review

OBJECTIVE

To address the fact that Black adults (BAs) experience significantly greater stroke burden than the general population, we conducted a systematic literature review which described evidence-based interventions targeting secondary stroke risk reduction in BAs.

DATA SOURCE

Publications were selected from PubMed, Ovid, Cochrane, and Web of Science databases. We included peer-reviewed, longitudinal, English-language studies performed in the USA which reported results for BAs separately and had adult participants who had experienced stroke-related events.

RESULTS

Six of the 7 studies employed behavioral interventions which promoted education on stroke risk factors, problem-solving skills, and healthy-coping strategies. These studies demonstrated improvements in one or more biologic outcomes including cholesterol control and systolic blood pressure.

CONCLUSIONS

Existing interventions on secondary stroke risk reduction approaches are effective in reducing secondary stroke risk among BAs, especially in individuals with poorly controlled blood pressure at baseline. However, additional research is needed because the current approaches may limit generalizability.

Comparative Effectiveness of Behavioral Interventions for Cardiovascular Risk Reduction in Latinos: A Systematic Review

BACKGROUND

Latinos, the fastest growing ethnic minority group in the United States, are at a high risk for cardiovascular disease (CVD). However, little is known about effective strategies to reduce CVD risk in this population.

OBJECTIVE

The aim of this study was to systematically review and synthesize evidence from randomized controlled trials that examined the effectiveness of behavioral interventions to reduce CVD risk in Latinos living in the United States.

METHODS

Four electronic databases were searched for relevant peer-reviewed English- and Spanish-language articles published between January 1, 2000, and December 31, 2019. Four reviewers independently completed article screening, data abstraction, and quality appraisal. At least 2 reviewers completed data abstraction and quality appraisal for each article, and a third reviewer was assigned to settle disagreements. Data on study characteristics and outcomes were abstracted.

RESULTS

We retrieved 1939 articles. After applying inclusion/exclusion criteria, 17 articles were included. Most interventions were led by community health workers (n = 10); 2 family-based interventions were identified. None of the included studies was nurse led. Behavioral factors were assessed across all included studies, whereas only 4 studies reported on psychosocial outcomes. Improvements were observed in dietary habits and psychosocial outcomes. Findings for physical activity and biological outcomes were mixed. We identified no differences in outcomes based on intervention modalities used or the role of those who led the interventions.

CONCLUSION

Existing evidence is mixed. Future research should assess the effectiveness of understudied treatment modalities (including nurse-led, mobile health, and family-based interventions) in reducing CVD risk in Latinos.

"Lessons Learned" Preventing Recurrent Ischemic Strokes through Secondary Prevention Programs: A Systematic Review

Recurrent ischemic strokes are a cause of significant healthcare burdens globally. Patients with uncontrolled vascular risk factors are more likely to develop recurrent ischemic strokes. This study aims to compile information gained from current secondary prevention programs. A pre-defined literature search strategy was applied to PubMed, SCOPUS, CINAHL, and Google Scholar databases, and studies from 1997 to 2020 were evaluated for quality, study aims, and outcomes. The search produced 1175 articles (1092 after duplicates were removed) and titles were screened; 55 titles were retained for the full-text analysis. Of the remaining studies, 31 were retained for assessment, five demonstrated long-term effectiveness, eight demonstrated short-term effectiveness, and 18 demonstrated no effectiveness. The successful studies utilized a variety of different techniques in the categories of physical fitness, education, and adherence to care plans to reduce the risk of recurrent strokes. The lessons we learned from the current prevention programs included (1) offer tailored care for underserved groups, (2) control blood pressure, (3) provide opportunities for medication dosage titration, (4) establish the care plan prior to discharge, (5) invest in supervised exercise programs, (6) remove barriers to accessing care in low resource settings, and (7) improve the transition of care.

Effect of Nurse Practitioner Interventions on Hospitalizations in the Community Transitions Intervention Trial

BACKGROUND

Despite improvements in hypertension treatment in the United States, Black and Hispanic individuals experience poor blood pressure control and have worse hypertension-related outcomes compared to Whites.

OBJECTIVE

The aim of the study was to determine the effect on hospitalization of supplementing usual home care (UHC) with two hypertension-focused transitional care interventions-one deploying nurse practitioners (NPs) and the other NPs plus health coaches.

METHODS

We examined post hoc the effect of two hypertension-focused NP interventions on hospitalizations in the Community Transitions Intervention trial-a three-arm, randomized controlled trial comparing the effectiveness of (a) UHC with (b) UHC plus a 30-day NP transitional care intervention or (c) UHC plus NP plus 60-day health coach intervention.

RESULTS

The study comprised 495 participants: mean age = 66 years; 57% female; 70% Black, non-Hispanic; 30% Hispanic. At the 3- and 12-month follow-up, all three groups showed a significant decrease in the average number of hospitalizations compared to baseline. The interventions were not significantly different from UHC.

CONCLUSION

The results of this post hoc analysis show that, during the study period, decreases in hospitalizations in the intervention groups were comparable to those in UHC, and deploying NPs provided no detectable value added. Future research should focus on testing ways to optimize UHC services.

Effect of a Coordinated Community and Chronic Care Model Team Intervention vs Usual Care on Systolic Blood Pressure in Patients With Stroke or Transient Ischemic Attack: The SUCCEED Randomized Clinical Trial

IMPORTANCE

Few stroke survivors meet recommended cardiovascular goals, particularly among racial/ethnic minority populations, such as Black or Hispanic individuals, or socioeconomically disadvantaged populations.

OBJECTIVE

To determine if a chronic care model-based, community health worker (CHW), advanced practice clinician (APC; including nurse practitioners or physician assistants), and physician team intervention improves risk factor control after stroke in a safety-net setting (ie, health care setting where all individuals receive care, regardless of health insurance status or ability to pay).

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial included participants recruited from 5 hospitals serving low-income populations in Los Angeles County, California, as part of the Secondary Stroke Prevention by Uniting Community and Chronic Care Model Teams Early to End Disparities (SUCCEED) clinical trial. Inclusion criteria were age 40 years or older; experience of ischemic or hemorrhagic stroke or transient ischemic attack (TIA) no more than 90 days prior; systolic blood pressure (BP) of 130 mm Hg or greater or 120 to 130 mm Hg with history of hypertension or using hypertensive medications; and English or Spanish language proficiency. The exclusion criterion was inability to consent. Among 887 individuals screened for eligibility, 542 individuals were eligible, and 487 individuals were enrolled and randomized, stratified by stroke type (ischemic or TIA vs hemorrhagic), language (English vs Spanish), and site to usual care vs intervention in a 1:1 fashion. The study was conducted from February 2014 to September 2018, and data were analyzed from October 2018 to November 2020.

INTERVENTIONS

Participants randomized to intervention were offered a multimodal coordinated care intervention, including hypothesized core components (ie, ≥3 APC clinic visits, ≥3 CHW home visits, and Chronic Disease Self-Management Program workshops), and additional telephone visits, protocol-driven risk factor management, culturally and linguistically tailored education materials, and self-management tools. Participants randomized to the control group received usual care, which varied by site but frequently included a free BP monitor, self-management tools, and linguistically tailored information materials.

MAIN OUTCOMES AND MEASURES

The primary outcome was change in systolic BP at 12 months. Secondary outcomes were non-high density lipoprotein cholesterol, hemoglobin A1c, and C-reactive protein (CRP) levels, body mass index, antithrombotic adherence, physical activity level, diet, and smoking status at 12 months. Potential mediators assessed included access to care, health and stroke literacy, self-efficacy, perceptions of care, and BP monitor use.

RESULTS

Among 487 participants included, the mean (SD) age was 57.1 (8.9) years; 317 (65.1%) were men, and 347 participants (71.3%) were Hispanic, 87 participants (18.3%) were Black, and 30 participants (6.3%) were Asian. A total of 246 participants were randomized to usual care, and 241 participants were randomized to the intervention. Mean (SD) systolic BP improved from 143 (17) mm Hg at baseline to 133 (20) mm Hg at 12 months in the intervention group and from 146 (19) mm Hg at baseline to 137 (22) mm Hg at 12 months in the usual care group, with no significant differences in the change between groups. Compared with the control group, participants in the intervention group had greater improvements in self-reported salt intake (difference, 15.4 [95% CI, 4.4 to 26.0]; P = .004) and serum CRP level (difference in log CRP, -0.4 [95% CI, -0.7 to -0.1] mg/dL; P = .003); there were no differences in other secondary outcomes. Although 216 participants (89.6%) in the intervention group received some of the 3 core components, only 35 participants (14.5%) received the intended full dose.

CONCLUSIONS AND RELEVANCE

This randomized clinical trial of a complex multilevel, multimodal intervention did not find vascular risk factor improvements beyond that of usual care; however, further studies may consider testing the SUCCEED intervention with modifications to enhance implementation and participant engagement.

Considerations in Addressing Social Determinants of Health to Reduce Racial/Ethnic Disparities in Stroke Outcomes in the United States

We write this article amid a global pandemic and a heightened awareness of the underlying structural racism in the United States, unmasked by the recent killing of George Floyd and multiple other unarmed Black Americans (Spring 2020). Our purpose is to highlight the role of social determinants of health (SDOH) on stroke disparities, to inspire dialogue, to encourage research to deepen our understanding of the mechanism by which SDOH impact stroke outcomes, and to develop strategies to address SDOH and reduce stroke racial/ethnic disparities. We begin by defining SDOH and health disparities in today's context; we then move to discussing SDOH and stroke, particularly secondary stroke prevention, and conclude with possible approaches to addressing SDOH and reducing stroke disparities. These approaches include (1) building on prior work; (2) enhancing our understanding of populations and subpopulations, including intersectionality, of people who experience stroke disparities; (3) prioritizing populations and points along the stroke care continuum when racial/ethnic disparities are most prominent; (4) understanding how SDOH impact stroke disparities in order to test SDOH interventions that contribute to the disparity; (5) partnering with communities; and (6) exploring technological innovations. By building on the prior work and expanding efforts to address SDOH, we believe that stroke disparities can be reduced.

Interventions Targeting Racial/Ethnic Disparities in Stroke Prevention and Treatment

Systemic racism is a public health crisis. Systemic racism and racial/ethnic injustice produce racial/ethnic disparities in health care and health. Substantial racial/ethnic disparities in stroke care and health exist and result predominantly from unequal treatment. This special report aims to summarize selected interventions to reduce racial/ethnic disparities in stroke prevention and treatment. It reviews the social determinants of health and the determinants of racial/ethnic disparities in care. It provides a focused summary of selected interventions aimed at reducing stroke risk factors, increasing awareness of stroke symptoms, and improving access to care for stroke because these interventions hold the promise of reducing racial/ethnic disparities in stroke death rates. It also discusses knowledge gaps and future directions.
