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

BackgroundRecurrent strokes are preventable through awareness and control of risk factors such as hypertension, and through lifestyle changes such as healthier diets, greater physical activity, and smoking cessation. However, vascular risk factor control is frequently poor among stroke survivors, particularly among socio-economically disadvantaged blacks, Latinos and other people of color. The Chronic Care Model (CCM) is an effective framework for multi-component interventions aimed at improving care processes and outcomes for individuals with chronic disease. In addition, community health workers (CHWs) have played an integral role in reducing health disparities; however, their effectiveness in reducing vascular risk among stroke survivors remains unknown. Our objectives are to develop, test, and assess the economic value of a CCM-based intervention using an Advanced Practice Clinician (APC)-CHW team to improve risk factor control after stroke in an under-resourced, racially/ethnically diverse population.Methods/designIn this single-blind randomized controlled trial, 516 adults (≥40 years) with an ischemic stroke, transient ischemic attack or intracerebral hemorrhage within the prior 90 days are being enrolled at five sites within the Los Angeles County safety-net setting and randomized 1:1 to intervention vs usual care. Participants are excluded if they do not speak English, Spanish, Cantonese, Mandarin, or Korean or if they are unable to consent. The intervention includes a minimum of three clinic visits in the healthcare setting, three home visits, and Chronic Disease Self-Management Program group workshops in community venues. The primary outcome is blood pressure (BP) control (systolic BP <130 mmHg) at 1 year. Secondary outcomes include: (1) mean change in systolic BP; (2) control of other vascular risk factors including lipids and hemoglobin A1c, (3) inflammation (C reactive protein [CRP]), (4) medication adherence, (5) lifestyle factors (smoking, diet, and physical activity), (6) estimated relative reduction in risk for recurrent stroke or myocardial infarction (MI), and (7) cost-effectiveness of the intervention versus usual care.DiscussionIf this multi-component interdisciplinary intervention is shown to be effective in improving risk factor control after stroke, it may serve as a model that can be used internationally to reduce race/ethnic and socioeconomic disparities in stroke in resource-constrained settings.Trial registrationClinicalTrials.gov Identifier NCT01763203.

Background and Purpose: Self-management programs may improve quality of life and self-efficacy for stroke survivors, but participation is low. In a randomized controlled trial of a complex, multidisciplinary, team-based secondary stroke prevention intervention, we offered participants Chronic Disease Self-Management Program (CDSMP) workshops in addition to clinic visits and home visits. To enhance participation, workshops were facilitated by community health workers who were culturally and linguistically concordant with most participants and scheduled CDSMP sessions at convenient venues and times. Over time, we implemented additional strategies such as free transportation and financial incentives. In this study, we aimed to determine factors associated with CDSMP participation and attendance. Methods: From 2014 to 2018, 18 CDSMP workshop series were offered to 241 English and Spanish-speaking individuals (age ≥40 years) with recent stroke or transient ischemic attack. Zero-inflated Poisson regression was used to identify factors associated with participation and attendance (ie, number of sessions attended) in CDSMP. Missing values were imputed using multiple imputation methods. Results: Nearly one-third (29%) of intervention subjects participated in CDSMP. Moderate disability and more clinic/home visits were associated with participation. Participants with higher numbers of clinic and home visits (incidence rate ratio [IRR], 1.06 [95% CI, 1.01–1.12]), severe (IRR, 2.34 [95% CI, 1.65–3.31]), and moderately severe disability (IRR, 1.55 [95% CI, 1.07–2.23]), and who enrolled later in the study (IRR, 1.12 [95% CI, 1.08–1.16]) attended more sessions. Individuals with higher chaos scores attended fewer sessions (IRR, 0.97 [95% CI, 0.95–0.99]). Conclusions: Less than one-third of subjects enrolled in the SUCCEED (Secondary Stroke Prevention by Uniting Community and Chronic Care Model Teams Early to End Disparities) intervention participated in CDSMP; however, participation improved as transportation and financial barriers were addressed. Strategies to address social determinants of health contributing to chaos and engage individuals in healthcare may facilitate attendance. REGISTRATION: URL: https://www.clinicaltrials.gov .

Background: Effective interventions to improve stroke preventative care in vulnerable populations have not been reported. Methods: We tested the impact of a chronic care model-based intervention program among 407 subjects with a recent stroke or transient ischemic attack at four Los Angeles County public hospitals. All subjects had a baseline systolic blood pressure (SBP) of at least 120 mm Hg and were randomized after baseline assessment in a 1:1 ratio to usual care or intervention, stratified by hospital and by English/Spanish language. The care management intervention was led by bilingual nurse practitioners or physician assistants, and it consisted of group clinics, self-management support, report cards, decision support, and coordination of ongoing care. Intention-to-treat analyses were conducted using repeated-measures mixed-effects models. The primary outcome was change in SBP. Secondary outcomes were other measures of SBP, low-density lipoprotein (LDL), ACC/AHA 10-year cardiovascular risk, adherence to antihypertensive and to antithrombotic medications, and physical activity. Results: Mean age was 57 years, 60% were male, 18% were African-American race, and 69% were Hispanic ethnicity. 48% had not graduated from high school. Baseline SBP was 150 mm Hg in the usual care arm and 149 mm Hg in the intervention arm. 12 month data were obtained in 333 participants (82%). There were substantial declines in SBP in both the usual care and intervention arms (Table). However, there were no significant differences between the two arms in either improvement of SBP from baseline or other measures of stroke risk factor control. Subgroup analyses did not reveal a differential impact of the intervention by race/ethnicity. Conclusion: Our care management intervention did not improve stroke risk factor control beyond what was attained in usual care. Further analyses are ongoing, and those findings will be used to guide modification of the intervention for future testing.

Background: Approximately 25 million people in the US are Limited English Proficient (LEP). LEP individuals are more likely to feel dissatisfied with the quality of healthcare when compared to the English proficient, but little is known about LEP stroke survivors. Objective: To evaluate differences in stroke literacy, self-efficacy, and perceptions of healthcare delivery in English and Spanish-speaking individuals enrolled in the Secondary stroke prevention by Uniting Community and Chronic care model teams Early to End Disparities (SUCCEED) trial. Methods: SUCCEED participants were given the option of receiving the intervention in English or Spanish. Baseline differences in stroke literacy (Schneider et al), self-efficacy (General Self-Efficacy Scale), and perceptions of care (Patient Assessment of Chronic Illness Care and Consumer Assessment of Healthcare Providers and Systems) were compared using T-test, Chi Square, and Fisher Exact in individuals who chose Spanish vs. English. Results: Of 487 participants, 207 preferred English and 280 chose Spanish. Despite feeling more worried about having a stroke (77 % vs. 67%), and feeling at risk of having a stroke (63% vs. 45%), Spanish-speakers were less likely to identify 3 stroke risk factors (19% vs. 33%, all p<0.05). Half of Spanish-speakers had difficulty understanding what was being told to them (50% vs. 30%), and less than half felt confident filling out medical forms (40% vs. 70%, both p<0.05). Spanish-speakers responded favorably about the ease of hospital admission or accessing medical care (80% vs. 55% and 72% vs. 53%), but responded negatively about providers spending enough time with them or explaining things in a way that was easy to understand (56% vs. 24% and 52% vs. 28%, all p<0.05). Spanish-speakers were more likely to feel that providers did not listen or respect what they had to say (52% vs. 22% and 44% vs. 17%, both p<0.05). Conclusion: Among stroke survivors, Spanish-speakers were more likely to have low stroke literacy, low self-efficacy, and a negative perception of healthcare delivery despite feeling that healthcare was accessible. Recognizing language barriers as a contributor to healthcare disparities, and tailoring interventions to address these barriers are crucial.
