Abstract
BACKGROUND People with stroke or transient ischaemic attack (TIA) are at increased risk of future stroke and other cardiovascular events. Stroke services need to be configured to maximise the adoption of evidence-based strategies for secondary stroke prevention. Smoking-related interventions were examined in a separate review so were not considered in this review. This is an update of our 2014 review. OBJECTIVES To assess the effects of stroke service interventions for implementing secondary stroke prevention strategies on modifiable risk factor control, including patient adherence to prescribed medications, and the occurrence of secondary cardiovascular events. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (April 2017), the Cochrane Effective Practice and Organisation of Care Group Trials Register (April 2017), CENTRAL (the Cochrane Library 2017, issue 3), MEDLINE (1950 to April 2017), Embase (1981 to April 2017) and 10 additional databases including clinical trials registers. We located further studies by searching reference lists of articles and contacting authors of included studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated the effects of organisational or educational and behavioural interventions (compared with usual care) on modifiable risk factor control for secondary stroke prevention. DATA COLLECTION AND ANALYSIS Four review authors selected studies for inclusion and independently extracted data. The quality of the evidence as 'high', 'moderate', 'low' or 'very low' according to the GRADE approach (GRADEpro GDT).Three review authors assessed the risk of bias for the included studies. We sought missing data from trialists.The results are presented in 'Summary of findings' tables. MAIN RESULTS The updated review included 16 new studies involving 25,819 participants, resulting in a total of 42 studies including 33,840 participants. We used the Cochrane risk of bias tool and assessed three studies at high risk of bias; the remainder were considered to have a low risk of bias. We included 26 studies that predominantly evaluated organisational interventions and 16 that evaluated educational and behavioural interventions for participants. We pooled results where appropriate, although some clinical and methodological heterogeneity was present.Educational and behavioural interventions showed no clear differences on any of the review outcomes, which include mean systolic and diastolic blood pressure, mean body mass index, achievement of HbA1c target, lipid profile, mean HbA1c level, medication adherence, or recurrent cardiovascular events. There was moderate-quality evidence that organisational interventions resulted in improved blood pressure control, in particular an improvement in achieving target blood pressure (odds ratio (OR) 1.44, 95% confidence interval (CI) 1.09 to1.90; 13 studies; 23,631 participants). However, there were no significant changes in mean systolic blood pressure (mean difference (MD), -1.58 mmHg 95% CI -4.66 to 1.51; 16 studies; 17,490 participants) and mean diastolic blood pressure (MD -0.91 mmHg 95% CI -2.75 to 0.93; 14 studies; 17,178 participants). There were no significant changes in the remaining review outcomes. AUTHORS' CONCLUSIONS We found that organisational interventions may be associated with an improvement in achieving blood pressure target but we did not find any clear evidence that these interventions improve other modifiable risk factors (lipid profile, HbA1c, medication adherence) or reduce the incidence of recurrent cardiovascular events. Interventions, including patient education alone, did not lead to improvements in modifiable risk factor control or the prevention of recurrent cardiovascular events.

Abstract
BACKGROUND AND OBJECTIVES Patients with coronary artery disease (CAD) are at high risk of recurrent adverse cardiac events. Such risk can be diminished through a guideline-recommend optimal medical therapy (OMT), defined as adherence to appropriate antiplatelet therapy, lipid-lowering agents, beta-blockers and angio.tensin-converting enzyme inhibitors, blood pressure < 140/90 mm Hg ( < 130/80 mm Hg in diabetics and renal disease patients), low-density lipoprotein (LDL) < 2 mmol/L, smoking cessation and aerobic physical activity, and hemoglobin (Hb) A1c < 7%. Unfortunately, preliminary data suggest a wide gap between recommended and actual practices. The study aims to estimate the rate of achieving of OMT in CAD patients in Qassim Province. DESIGN AND SETTINGS This observational study enrolled 207 consecutive CAD patients seen in cardiology clinic in Prince Sultan Cardiac Center in Qassim between January 2012 and May 2012. METHODS Eligible participants were over the age of 18, with CAD documented by either noninvasive testing or by coronary angiogram. We collected the demographic, medications, laboratory, and clinical data through in-person interviews, medical records, and an electronic patient database. RESULTS OMT was achieved in only 10.4% of CAD patients. The rate of achievement of target systolic blood pressure was 76.5%, target diastolic blood pressure 88%, target LDL 68%, adherence to medications 91%. Diabetes was common (64% of all patients), and only 24% of these patients achieved the target HbA1c. CONCLUSION The poor achievement of optimal medical therapy in CAD patients contributes to prevent.able mortality, morbidity, and health care costs. The observed shortcomings warrant investment in strategies to achieve OMT in these high-risk patients.

Abstract
CONTEXT Uncontrolled hypertension remains a widely prevalent cardiovascular risk factor in the U.S. team-based care, established by adding new staff or changing the roles of existing staff such as nurses and pharmacists to work with a primary care provider and the patient. Team-based care has the potential to improve the quality of hypertension management. The goal of this Community Guide systematic review was to examine the effectiveness of team-based care in improving blood pressure (BP) outcomes. EVIDENCE ACQUISITION An existing systematic review (search period, January 1980-July 2003) assessing team-based care for BP control was supplemented with a Community Guide update (January 2003-May 2012). For the Community Guide update, two reviewers independently abstracted data and assessed quality of eligible studies. EVIDENCE SYNTHESIS Twenty-eight studies in the prior review (1980-2003) and an additional 52 studies from the Community Guide update (2003-2012) qualified for inclusion. Results from both bodies of evidence suggest that team-based care is effective in improving BP outcomes. From the update, the proportion of patients with controlled BP improved (median increase=12 percentage points); systolic BP decreased (median reduction=5.4 mmHg); and diastolic BP also decreased (median reduction=1.8 mmHg). CONCLUSIONS Team-based care increased the proportion of people with controlled BP and reduced both systolic and diastolic BP, especially when pharmacists and nurses were part of the team. Findings are applicable to a range of U.S. settings and population groups. Implementation of this multidisciplinary approach will require health system-level organizational changes and could be an important element of the medical home.

Overall the studies were of reasonable quality, but one study was considered at high risk of bias. Fifteen studies evaluated predominantly organisational interventions and 11 studies evaluated educational and behavioural interventions for patients. Results were pooled where appropriate, although some clinical and methodological heterogeneity was present. The estimated effects of organisational interventions were compatible with improvements and no differences in the modifiable risk factors mean systolic blood pressure (mean difference (MD) -2.57 mmHg; 95% confidence interval (CI) -5.46 to 0.31), mean diastolic blood pressure (MD -0.90 mmHg; 95% CI -2.49 to 0.68), blood pressure target achievement (OR 1.24; 95% CI 0.94 to 1.64) and mean body mass index (MD -0.68 kg/m(2); 95% CI -1.46 to 0.11). There were no significant effects of organisational interventions on lipid profile, HbA1c, medication adherence or recurrent cardiovascular events. Educational and behavioural interventions were not generally associated with clear differences in any of the review outcomes, with only two exceptions. AUTHORS' CONCLUSIONS Pooled results indicated that educational interventions were not associated with clear differences in any of the review outcomes. The estimated effects of organisational interventions were compatible with improvements and no differences in several modifiable risk factors. We identified a large number of ongoing studies, suggesting that research in this area is increasing. The use of standardised outcome measures would facilitate the synthesis of future research findings.

Abstract
Low-socioeconomic-status (SES) Latinos are disproportionately represented among the 78 million obese Americans. Tailored behavioral weight-loss interventions show promise, but there is limited adaptation to lower-SES Latino immigrants. This study provides guidance for tailoring obesity-reduction strategies for this population by evaluating food security, educational community resource utilization, education level, depression, sex, and length of US residence as predictors of diet and physical activity. The cross-sectional study used baseline data collected in July 2009 through September 2010 for a weight-loss trial among lower-SES obese (body mass index 30 to 55) Latino immigrants who were enrolled at a community health clinic (n=207). Physical activity was measured using 7-day pedometer recording. Dietary intake was measured using an interviewer-administered food frequency questionnaire. Factors assessed by questionnaire included education community resource use (nutrition and physical activity classes), education level, US residence (years), food security, and depressive symptoms. Data were analyzed using multivariate-adjusted linear regression models. More than one third of participants were sedentary (<5,000 steps/day), and 41% had low fruit and vegetable intake (<5 servings/day). In multivariate-adjusted models, educational community resource use, male sex, less education, fewer depressive symptoms, and shorter US residence time were associated with more physical activity (all, P ≤ 0.05). Educational community resource use was positively associated with fruit and vegetable intake (P=0.05). Male sex was associated with more sweet-beverage intake (P=0.02) and fast-food intake (P=0.04). Fewer depressive symptoms were associated with lower sweet-beverage intake (P=0.05). In conclusion, obesity-reduction strategies among low-SES Latino immigrants might effectively emphasize educational community resource use and interventions tailored for psychosocial and sociodemographic characteristics.

Abstract
Adult and childhood obesity and related adverse outcomes are most common among racial/ethnic minorities and socio-economically disadvantaged populations in the United States . Research approaches to obesity developed in mainstream populations and deploying new information technologies may exacerbate existing disparities in obesity. Current obesity management and prevention research priorities will not maximally impact this critical problem unless investigators explicitly focus on discovering innovative strategies for preventing and managing obesity in the disadvantaged populations that are most affected. On the basis of our research experience, four key research approaches are needed: (1) elucidating the underlying social forces that lead to disparities; (2) directly involving community members in the development of research questions and research methods; (3) developing flexible strategies that allow tailoring to multiple disadvantaged populations; and (4) building culturally and socio-economically tailored strategies specifically for populations most affected by obesity. Our experience with a community-based longitudinal cohort study and two health center-based clinical trials illustrate these principles as a contrast to traditional research priorities that can inadvertently worsen existing social inequities. If obesity research does not directly address healthcare and health-outcome disparities, it will contribute to their perpetuation.

Abstract
Background Obesity exerts an enormous health impact through its effect on coronary heart disease and its risk factors. Primary care-based and community-based intensive lifestyle counseling may effectively promote weight loss. There has been limited implementation and evaluation of these strategies, particularly the added benefit of community-based intervention, in low-income Latino populations. Design The Vivamos Activos Fair Oaks project is a randomized clinical trial designed to evaluate the clinical and cost-effectiveness of two obesity reduction lifestyle interventions: clinic-based intensive lifestyle counseling, either alone (n = 80) or combined with community health worker support (n = 80), in comparison to usual primary care (n = 40). Clinic-based counseling consists of 15 group and four individual lifestyle counseling sessions provided by health educators targeting behavior change in physical activity and dietary practices. Community health worker support includes seven home visits aimed at practical implementation of weight loss strategies within the person's home and neighborhood. The interventions use a framework based on Social Cognitive Theory, the Transtheoretical Model of behavior change, and techniques from previously tested lifestyle interventions. Application of the framework was culturally tailored based on past interventions in the same community and elsewhere, as well as a community needs and assets assessment. The interventions include a 12-month intensive phase followed by a 12-month maintenance phase. Participants are obese Spanish-speaking adults with at least one cardiovascular risk factor recruited from a community health center in a low-income neighborhood of San Mateo County, California. Follow-up assessments occur at 6, 12, and 24 months for the primary outcome of percent change in body mass index at 24 months. Secondary outcomes include specific cardiovascular risk factors, particularly blood pressure and fasting glucose levels. Discussion and Conclusions If successful, this study will provide evidence for broad implementation of obesity interventions in minority populations and guidance about the selection of strategies involving clinic-based case management and community-based community health worker support.

Abstract
BACKGROUND Case management (CM) is a systematic approach to supplement physician-centered efforts to prevent cardiovascular disease (CVD). Research is limited on its implementation and efficacy in low-income, ethnic minority populations. METHODS We conducted a randomized clinical trial to evaluate a nurse- and dietitian-led CM program for reducing major CVD risk factors in low-income, primarily ethnic minority patients in a county health care system, 63.0% of whom had type 2 diabetes mellitus. The primary outcome was the Framingham risk score (FRS). RESULTS A total of 419 patients at elevated risk of CVD events were randomized and followed up for a mean of 16 months (81.4% retention). The mean FRS was significantly lower for the CM vs usual care group at follow-up (7.80 [95% confidence interval, 7.21-8.38] vs 8.93 [8.36-9.49]; P = .001) after adjusting for baseline FRS. This is equivalent to 5 fewer heart disease events per 1000 individuals per year attributable to the intervention or to 200 individuals receiving the intervention to prevent 1 event per year. The pattern of group differences in the FRS was similar in subgroups defined a priori by sex and ethnicity. The main driver of these differences was lowering the mean (SD) systolic (-4.2 [18.5] vs 2.6 [22.7] mm Hg; P = .003) and diastolic (-6.0 [11.6] vs -3.0 [11.7] mm Hg; P = .02) blood pressures for the CM vs usual care group. CONCLUSION Nurse and dietitian CM targeting multifactor risk reduction can lead to modest improvements in CVD risk factors among high-risk patients in low-income, ethnic minority populations receiving care in county health clinics.

Abstract
OBJECTIVE A common form of validation study compares alternative methods for collecting data. The Bland-Altman plot pairs observations across methods and plots their mean values vs. their difference. This method provides only limited information, however, when the range of observed values is small relative to the number of observations. This brief report shows how adding a simple bar chart to a Bland-Altman plot adds essential additional information. STUDY DESIGN AND SETTING The methodological approach is illustrated using data from a randomized controlled clinical trial of patients in a U.S. county health system. RESULTS When the number of unique values is small, a Bland-Altman plot alone may provide inadequate information. Adding a bar chart yields new and essential information about agreement, bias, and heteroscedasticity. CONCLUSION Studies validating one data-collection method against another can be performed successfully even when the number of unique values is small.

Abstract
Essential hypertension is the most common diagnosis in US primary care settings for middle-aged persons and seniors. Yet, data on hypertension screening, treatment, and control in such settings are limited. We analyzed National Ambulatory Medical Care Survey data to examine the rates of and factors associated with hypertension screening, treatment, and control during US office visits in 2003 and 2004. Blood pressure was measured in 56% (95% confidence limits: 52% to 59%) of all visits by patients > or =18 years of age and in 93% (95% confidence limits: 89% to 96%) of hypertensive patient visits. Among the latter, 62% (95% confidence limits: 55% to 69%) were treated. Diuretics were the most commonly prescribed antihypertensive agents (46%; 95% confidence limits: 41% to 50%), and combination therapy was reported in 58% (95% confidence limits: 54% to 63%) of treated visits. Only 39% (95% confidence limits: 34% to 43%) of treated visits were at recommended blood pressure goals. The odds of not being screened for hypertension were notably greater for visits with a provider other than a primary care physician or cardiologist (10.0; 95% confidence limits: 5.5 to 16.7) and for nonwell care visits (5.6; 95% confidence limits: 3.6 to 8.3). Greater odds of not being treated for hypertension were noted by geographic region (South versus Northeast: 2.6; 95% confidence limits: 1.2 to 5.6) and visit type (first time versus return visits; 1.6; 95% confidence limits: 1.1 to 2.4). The odds of not having blood pressure controlled were greater for patients with comorbidities (1.6; 95% confidence limits: 1.1 to 2.4). In conclusion, more intervention efforts are needed to further reduce the gaps and variations in routine practice in relation to evidence-based practice guidelines for hypertension screening, treatment, and control.

Abstract
METHODS Case-management (CM) can positively influence chronic disease care by facilitating guideline-concordant interventions that improve outcomes through intensive, individualized, longitudinal care. Implementation of CM, however, is difficult. We have identified lessons learned from a cardiovascular risk reduction CM program that may aid future CM implementation. INTRODUCTION Heart to Heart is both a clinical trial and program dissemination project implementing CM for persons at elevated risk of coronary heart disease (CHD) events in a multiethnic, low-income population in a county health system. Patients were randomized to CM plus usual primary care (N = 212) or primary care alone (N = 207). CM patients received face-to-face nurse and dietitian visits (mean of 14 hours) over 17 months. Visits emphasized behavior change, risk-factor monitoring, and guideline-based pharmacotherapy. A total of 341 patients (81%) were available for follow-up. This CM model is currently transitioning to a County-run program. RESULTS Findings demonstrated statistically significant reductions in mean Framingham Risk for CM versus usual primary care (1.56% absolute decrease in 10-year CHD risk, P = 0.007). Favorable changes were noted across most major CHD risk factors. Lessons learned are the need for the following: (1) Strategies for implementing CM in low-income, ethnically-diverse populations, (2) Methods for developing clinically more effective CM, and (3) Approaches to increase the efficiency of cardiovascular CM. CONCLUSIONS CM for cardiac risk factors faces notable implementation barriers, particularly in County health systems. Specific implementation solutions recommended may help confront these barriers and improve diffusion of this evidence-based and patient centered model of care.

Abstract
Case management (CM) is an important strategy for chronic disease care. By utilizing non-physician providers for conditions requiring ongoing care and follow-up, CM can facilitate guideline-concordant care, patient empowerment, and improvement in quality of life. We identify a series of critical factors required for successful CM implementation. Heart to Heart is a clinical trial evaluating CM for coronary heart disease (CHD) risk reduction in a multiethnic, low-income population. Patients at elevated cardiac risk were randomized to CM plus primary care (212 patients) or to primary care alone (207). Over a mean follow-up of 17 months, patients received face-to-face nurse and dietitian visits. Mean contact time was 14 hours provided at an estimated cost of $1250 per patient for the 341 (81%) patients completing follow-up. Visits emphasized behavior change, risk-factor monitoring, self-management skills, and guideline-based pharmacotherapy. A statistically significant reduction in mean Framingham risk probability occurred in CM plus primary care relative to primary care alone (1.6% decrease in 10-year CHD risk, p = 0.007). Favorable changes were noted across individual risk factors. Our findings suggest that successful CM implementation relies on choosing appropriate case managers and investing in training, integrating CM into existing care systems, delineating the scope and appropriate levels of clinical decision making, using information systems, and monitoring outcomes and costs. While our population, setting, and intervention model are unique, these insights are broadly relevant. If implemented with attention to critical factors, CM has great potential to improve the process and outcomes of chronic disease care.
