Understanding the implementation and sustainability needs of evidence-based programs for racial and ethnic minoritized older adults in under-resourced communities with limited aging services.

BACKGROUND: Evidence-based programs (EBPs) for older adults effectively improve health outcomes. However, there is a limited understanding of the unique needs of service providers as they consider adopting, implementing, and maintaining programs for older minority adults in low-income communities with limited aging services. METHODS: We conducted semi-structured interviews with key informants of community-based organizations (CBOs) to understand implementation and sustainability needs of CBOs within four racial and ethnically diverse Los Angeles County geographic areas. We performed thematic analysis of interview transcripts. RESULTS: Interviews were conducted with representatives from 25 senior-serving agencies providing aging-related EBPs. CBO representatives reported implementing EBPs in 8 domains: Falls Prevention (68%), Mental Health (64%), Caregiver Health (48%), Chronic Disease Management (48%), Diabetes Management (36%), Arthritis Management (28%), Physical Activity (24%), and Multiple Conditions Management (8%). Themes are presented using the six domains of the Bass and Judge framework for factors impacting successful and sustained EBP implementation. CBOs in low-income and diverse communities described unique challenges with tailoring interventions based on local community context (literacy, language), cultural context, and locally available resources (technology, safe community spaces, transportation) and faced resource-intensive administrative burdens through staff turnover, data collection, sustainable funding, and networking. CONCLUSIONS: Serving racial and ethnic communities has unique challenges that require tailored approaches and additional resources to ensure equitable access to EBPs for all communities. We describe suggestions for enhancing the effective adoption of EBPs among service agencies in under-resourced and diverse aging communities serving populations with aging-related health disparities.

Community-based organization perspectives on participating in state-wide community canvassing program aimed to reduce COVID-19 vaccine disparities in California.

BACKGROUND: Inequities in COVID-19 vaccine accessibility and reliable COVID-related information disproportionately affected marginalized racial and ethnic communities in the U.S. The Get Out the Vaccine (GOTVax) program, an innovative statewide government-funded COVID-19 vaccine canvassing program in California, aimed to reduce structural barriers to COVID-19 vaccination in high-risk communities with low vaccination rates. GOTVax consisted of a community-academic-government partnership with 34 local trusted community-based organizations' (CBOs) to conduct COVID-19 vaccine outreach, education, and vaccine registration. The purpose of this qualitative evaluation study was to explore the barriers and facilitators of using local CBOs to deploy a geographically, racially, and ethnically diverse state-wide COVID-19 vaccine outreach program. METHODS: Semi-structured online interviews were conducted with participating GOTVax CBO leaders from November 2021 to January 2022. Transcripts were analyzed using reflexive thematic analysis. RESULTS: Thirty-one of 34 CBOs participated (91% response rate). Identified themes encompassed both facilitators and barriers to program participation. Key facilitators included leveraging trust through recognized entities; promoting empathetic, tailored outreach; and flexibility of milestone-based CBO funding contracts for rapid program implementation. Barriers included navigating community sociopolitical, geographic, and cultural factors; managing canvassers' safety; desiring metrics for self-evaluation of outreach success; mitigating canvassing technology challenges; and concerns of program infrastructure initially limiting outreach. CBOs problem-solved barriers with academic and government partners. CONCLUSIONS: Between May and December 2021, the GOTVax program reached over 2 million California residents and registered over 60,000 residents for COVID-19 vaccination. Public health campaigns may improve benefits from leveraging the expertise of community-trusted CBOs and universities by providing flexible infrastructure and funding, allowing CBOs to seamlessly tailor outreach most applicable to local minoritized communities.

Geospatial analysis of access to dermatology care in Los Angeles County: a cross sectional study.

Geographic maldistribution of dermatologists contributes to disparities in access to dermatologic care. We aimed to investigate the geographic distribution of, and differences in wait times for medical dermatology services in Los Angeles County (LAC). We placed phone calls to 251 dermatology practices in LAC to ask for a new patient appointment for a changing mole. We found West LAC (Service Planning Area [SPA] 5) had the highest number of dermatologists and South LAC (SPA 6) had the lowest (26.1 versus 0 per 100,000 residents, P=0.01). Service Planning Area 6 has a higher non-White, uninsured, and impoverished population than SPA 5. Dermatology appointment wait times and Medicaid acceptance varied between SPAs but was not statistically significant (P=0.37 and P=0.20, respectively). Medicaid-accepting practices had a significantly longer mean wait time for an appointment than practices that did not accept Medicaid (26.1 versus 15.1 days, P=0.003). Regions with predominantly non-White, Spanish-speaking, and medically underinsured residents were found to be disproportionately lacking in dermatologists across LAC, which may contribute to impaired access to dermatology services in LAC.

Fishing for health: Neighborhood variation in fish intake, fish quality and association with stroke risk among older adults in the Cardiovascular Health Study.

BACKGROUND AND AIMS: Fish consumption has been associated with better health outcomes. Dietary patterns may vary substantially by neighborhood of residence. However, it is unclear if the benefits of a healthy diet are equivalent in different communities. This study examines associations of fish consumption with stroke incidence and stroke risk factors, and whether these differ by neighborhood socioeconomic status (NSES). METHODS AND RESULTS: We studied 4007 participants in the Cardiovascular Health Study who were 65 years or older and recruited between 1989 and 1990 from 4 US communities. Outcomes included fish consumption type (bakes/broiled vs. fried) and frequency, stroke incidence, and stroke risk factors. Multilevel regressions models were used to estimate fish consumption associations with clinical outcomes. Lower NSES was associated with higher consumption of fried fish (aOR = 1.47, 95% CI: 1.10-1.98) and lower consumption of non-fried fish (0.64, 0.47-0.86). Frequent fried fish (11.9 vs. 9.2 person-years for at least once weekly vs. less than once a month, respectively) and less frequent non-fried fish (17.7 vs. 9.6 person-years for less than once a month vs. at least once weekly, respectively) were independently associated with an increased risk of stroke (p-values < 0.05). However, among those with similar levels of healthy fish consumption, residents with low NSES had less benefit on stroke risk reduction, compared with high NSES. CONCLUSION: Fish consumption type and frequency both impact stroke risk. Benefits of healthy fish consumption differ by neighborhood socioeconomic status.

Community-based organizations' perspectives on improving health and social service integration.

BACKGROUND: Collaborations between health systems and community-based organizations (CBOs) are increasingly common mechanisms to address the unmet health-related social needs of high-risk populations. However, there is limited evidence on how to develop, manage, and sustain these partnerships, and implementation rarely incorporates perspectives of community social service organizations. To address these gaps, we elicited CBOs' perspectives on service delivery for clients, the impact of the Whole Person Care-Los Angeles (WPC-LA) initiative to integrate health and social care, and their suggestions for improving health system partnerships. METHODS: Using stakeholder engaged principles and a qualitative Rapid Assessment Process, we conducted brief surveys and in-depth semi-structured interviews with 65 key informants from 36 CBOs working with WPC-LA. RESULTS: Major themes identified by CBOs included: 1) the importance of a holistic, client-centered, continuously engaged approach that is reliant on regional partnerships; 2) benefits of WPC-LA expanding capacity and networks; 3) concerns about communication and redundancy hindering WPC-LA; and 4) a need for more equitable partnerships incorporating their approaches. CONCLUSIONS: CBOs value opportunities for integration with health systems, bring critical expertise to these partnerships, and seek to strengthen cross-sector collaborations. Early, equitable, and inclusive participation in the development and implementation of these partnerships may enhance their effectiveness, but requires policy that prioritizes and incentivizes sustainable and mutually beneficial partnerships.

Enhancing existing medical school curricula with an innovative healthcare disparities curriculum.

BACKGROUND: Effective healthcare disparities curricula seek to train physicians who are well equipped to address the health needs of an increasingly diverse society. Current literature on healthcare disparities curricula and implementation focuses on courses created independent of existing educational materials. Our aim was to develop and implement a novel resource-conserving healthcare disparities curriculum to enhance existing medical school lectures without the need for additional lectures. METHODS: This non-randomized intervention was conducted at the University of California Los Angeles. The curriculum was offered to all first-year medical students in the class of 2021 (n=188). With institutional approval, a new healthcare disparities curriculum was created based on the Society of General Internal Medicine's core learning objectives for effective healthcare disparities curricula (J General Internal Med 25:S160-163, 2010). Implementation of the curriculum made use of "teachable moments" within existing medical school lectures. Teachable moments were broad lecture topics identified by the research team as suitable for introducing relevant healthcare disparities content. The new lecture-enhancing healthcare disparities curriculum was delivered with the related lecture via integrated PDF documents uploaded to an online learning management system. Students were encouraged to complete pre- and post- course assessments to examine changes in disparities knowledge and self-rated confidence in addressing disparities. Matched χ2 tests were used for statistical analysis. RESULTS: Participating students (n=92) completed both pre- and post-course assessments and were retrospectively stratified, based on self-reported use of the new lecture enhancing curriculum, into the "high utilizer" group (use of materials "sometimes" or "very often," n=52) and the comparison "low utilizer" group (use of the materials "rarely" or "very rarely," n=40). Students who self-identified as underrepresented racial and ethnic minorities in medicine were more likely to utilize the material (41% of the high utilizers vs. 17% of the low utilizer group, p<.01). Post-course knowledge assessment scores and self-reported confidence in addressing healthcare disparities improved only in the high utilizer group. CONCLUSIONS: Integrating new guideline based curricula content simultaneously into pre-existing lectures by identifying and harnessing teachable moments may be an effective and resource-conserving strategy for enhancing healthcare disparities education among first year medical students.

Trends in Racial/Ethnic and Nativity Disparities in Cardiovascular Health Among Adults Without Prevalent Cardiovascular Disease in the United States, 1988 to 2014.

Background: Trends in cardiovascular disparities are poorly understood, even as diversity increases in the United States. Objective: To examine U.S. trends in racial/ethnic and nativity disparities in cardiovascular health. Design: Repeated cross-sectional study. Setting: NHANES (National Health and Nutrition Examination Survey), 1988 to 2014. Participants: Adults aged 25 years or older who did not report cardiovascular disease. Measurements: Racial/ethnic, nativity, and period differences in Life's Simple 7 (LS7) health factors and behaviors (blood pressure, cholesterol, hemoglobin A1c, body mass index, physical activity, diet, and smoking) and optimal composite scores for cardiovascular health (LS7 score ≥10). Results: Rates of optimal cardiovascular health remain below 40% among whites, 25% among Mexican Americans, and 15% among African Americans. Disparities in optimal cardiovascular health between whites and African Americans persisted but decreased over time. In 1988 to 1994, the percentage of African Americans with optimal LS7 scores was 22.8 percentage points (95% CI, 19.3 to 26.4 percentage points) lower than that of whites in persons aged 25 to 44 years and 8.0 percentage points (CI, 6.4 to 9.7 percentage points) lower in those aged 65 years or older. By 2011 to 2014, differences decreased to 10.6 percentage points (CI, 7.4 to 13.9 percentage points) and 3.8 percentage points (CI, 2.5 to 5.0 percentage points), respectively. Disparities in optimal LS7 scores between whites and Mexican Americans were smaller but also decreased. These decreases were due to reductions in optimal cardiovascular health among whites over all age groups and periods: Between 1988 to 1994 and 2011 to 2014, the percentage of whites with optimal cardiovascular health decreased 15.3 percentage points (CI, 11.1 to 19.4 percentage points) for those aged 25 to 44 years and 4.6 percentage points (CI, 2.7 to 6.5 percentage points) for those aged 65 years or older. Limitation: Only whites, African Americans, and Mexican Americans were studied. Conclusion: Cardiovascular health has declined in the United States, racial/ethnic and nativity disparities persist, and decreased disparities seem to be due to worsening cardiovascular health among whites rather than gains among African Americans and Mexican Americans. Multifaceted interventions are needed to address declining population health and persistent health disparities.

The Healthy Community Neighborhood Initiative: Rationale and Design.

OBJECTIVE: To describe the design and rationale of the Healthy Community Neighborhood Initiative (HCNI), a multi-component study to understand and document health risk and resources in a low-income and minority community. DESIGN: A community-partnered participatory research project. SETTING: A low-income, biethnic African American and Latino neighborhood in South Los Angeles. PARTICIPANTS: Adult community residents aged >18 years. MAIN OUTCOME MEASURES: Household survey and clinical data collection; neighborhood characteristics; neighborhood observations; and community resources asset mapping. RESULTS: We enrolled 206 participants (90% of those eligible), of whom 205 completed the household interview and examination, and 199 provided laboratory samples. Among enrollees, 82 (40%) were aged >50 years and participated in functional status measurement. We completed neighborhood observations on 93 street segments; an average of 2.2 (SD=1.6) study participants resided on each street segment observed. The community asset map identified 290 resources summarized in a Community Resource Guide given to all participants. CONCLUSIONS: The HCNI community-academic partnership has built a framework to assess and document the individual, social, and community factors that may influence clinical and social outcomes in a community at high-risk for preventable chronic disease. Our project suggests that a community collaborative can use culturally and scientifically sound strategies to identify community-centered health and social needs. Additional work is needed to understand strategies for developing and implementing interventions to mitigate these disparities.

Carotid artery stenosis: wide variability in reporting formats--a review of 127 Veterans Affairs medical centers.

PURPOSE: To determine whether radiology reports describe clinically significant carotid arterial stenosis in a consistent format that is actionable by ordering clinicians. MATERIALS AND METHODS: This study was HIPAA compliant. Informed consent was waived. Institutional review board approval was obtained for this retrospective chart review, which included radiology reports of carotid artery imaging for patients hospitalized with ischemic stroke at 127 Veterans Affairs medical centers in 2006-2007. "Clinically significant results" were defined as results with at least 50% stenosis or at least moderate stenosis, excluding complete occlusion. How often clinically significant results were reported as an exact percentage stenosis (such as 60%), range (such as 50%-69%), or category (such as moderate) was determined. Among results reported as a range, how often the range bracketed clinical thresholds of 50% and 70% (typically used to determine appropriateness of carotid arterial revascularization) was determined. RESULTS: Among 2675 patients, there were 6618 carotid imaging results, of which 1015 (15%) were considered clinically significant. Among 695 clinically significant results at ultrasonography (US), 348 (50%) were described as a range, and another 314 (45%) were reported as an exact percentage stenosis. Among the 348 clinically significant US results reported as a range, 259 (74%) bracketed the thresholds of 50% or 70%. For magnetic resonance angiographic results, 48% (106 of 221) qualitatively described clinically significant results as a category, 38% (84 of 221) as an exact percentage stenosis, and 14% (31 of 221) as a range. CONCLUSION: In this national health care system, the manner in which clinically significant carotid arterial stenosis was reported varied widely.

Injuries in adolescents with childhood-onset epilepsy compared with sibling controls.

OBJECTIVE: To compare the occurrence of injuries in adolescents with childhood-onset epilepsy and matched sibling controls. STUDY DESIGN: Retrospective case-control lifetime injury assessments were obtained from a community-based cohort of adolescents with childhood-onset epilepsy diagnosed 9 years earlier and their siblings. The children with epilepsy (n = 501; mean age, 15.3 years) included those with complicated (abnormal neurologic examination or IQ <80; n = 133) and uncomplicated (normal neurologic examination and IQ ≥80; n = 368) epilepsy. Children with uncomplicated epilepsy were matched to sibling controls (n = 210 pairs). The children reported whether or not they had ever (before and after epilepsy diagnosis) experienced injuries "serious enough to require medical attention" and if so, the type of treatment required. RESULTS: Almost one-half (49.1%) of the children with epilepsy experienced injury, of whom 8.9% required surgery/hospitalization and 17.1% had injury related to a seizure. Fewer children with uncomplicated epilepsy had seizure-related injuries versus those with complicated epilepsy (13.6% vs 27.4%; P ≤ .01). The proportion of children with epilepsy with any injury by type (not mutually exclusive) were: 25.2% with fractures (n = 126); 24.4% with head injuries (n = 122); 10.2% with other injuries (n = 51); 8.4% with dental injuries (n = 42); and 8% with burns/scalds (n = 40). A similar proportion of children with uncomplicated epilepsy experienced any injury (overall and by type) compared to matched sibling controls, with the exception that more children with uncomplicated epilepsy had head injuries (30.0% vs 19.5%; P < .02). CONCLUSION: With the exception of head injuries, we found no evidence of an increased risk of injury in a representative cohort of children with epilepsy compared with matched sibling controls. This finding may reflect the fact that the sample was not biased to more severe cases, or that safety precautions to prevent injury were widely used.

Associations of sleep disturbance symptoms with health-related quality of life in Parkinson's disease.

The authors examined associations of various sleep-disturbance symptoms with health-related quality of life (HRQOL) in 153 adults with Parkinson's disease (PD). PD patients reported more snoring, sleep inadequacy, daytime somnolence, and sleep-maintenance problems than the general population. Symptoms having the broadest and strongest unique associations with generic HRQOL (eight scales; two composites of SF-36) were daytime somnolence (five scales; one composite), sleep initiation (eight scales; two composites), and awakening short of breath or with headache (six scales; two composites). Associations of selected sleep-disturbance symptoms--some unanticipated--suggest that assessing specific symptoms is worthwhile in clinical care.

Exploring psychosocial pathways between neighbourhood characteristics and stroke in older adults: the cardiovascular health study.

OBJECTIVES: to investigate whether psychosocial pathways mediate the association between neighbourhood socioeconomic disadvantage and stroke. METHODS: prospective cohort study with a follow-up of 11.5 years. SETTING: the Cardiovascular Health Study, a longitudinal population-based cohort study of older adults ≥65 years. MEASUREMENTS: the primary outcome was adjudicated incident ischaemic stroke. Neighbourhood socioeconomic status (NSES) was measured using a composite of six census-tract variables. Psychosocial factors were assessed with standard measures for depression, social support and social networks. RESULTS: of the 3,834 white participants with no prior stroke, 548 had an incident ischaemic stroke over the 11.5-year follow-up. Among whites, the incident stroke hazard ratio (HR) associated with living in the lowest relative to highest NSES quartile was 1.32 (95% CI = 1.01-1.73), in models adjusted for individual SES. Additional adjustment for psychosocial factors had a minimal effect on hazard of incident stroke (HR = 1.31, CI = 1.00-1.71). Associations between NSES and stroke incidence were not found among African-Americans (n = 785) in either partially or fully adjusted models. CONCLUSIONS: psychosocial factors played a minimal role in mediating the effect of NSES on stroke incidence among white older adults.

Seizure recency and quality of life in adolescents with childhood-onset epilepsy.

Health-related quality of life (HRQOL) is associated with seizure recency among adults with epilepsy. In a prospective, community-based study of long-term outcomes of childhood-onset epilepsy, we evaluated whether worse HRQOL is associated with more recent seizures among children and adolescents with epilepsy. We used the Child Health Questionnaire (CHQ), a generic measure with child and parent-proxy versions, to measure HRQOL. Among 277 children with epilepsy (CWE) assessed 9 years after diagnosis, parent-proxy reported but not child self-reported HRQOL was significantly worse for those having seizures in the prior year than for those who were seizure free ≥1 year across the majority of scales. There were no differences between CWE in remission for 1-5 years and those seizure free ≥5 years for child and parent-proxy reported HRQOL with the exception of the parent Emotional Impact scale, suggesting that HRQOL differences related to seizure recency level off after the initial year of remission.

Predictors of acceptance of offered care management intervention services in a quality improvement trial for dementia.

OBJECTIVE: Care management approaches have been proven to improve outcomes for patients with dementia and their family caregivers (dyads). However, acceptance of services in these programs is incomplete, impacting effectiveness. Acceptance may be related to dyad as well as healthcare system characteristics, but knowledge about factors associated with program acceptance is lacking. This study investigates patient, caregiver, and healthcare system characteristics associated with acceptance of offered care management services. METHODS: This study analyzed data from the intervention arm of a cluster randomized controlled trial of a comprehensive dementia care management intervention. There were 408 patient-caregiver dyads enrolled in the study, of which 238 dyads were randomized to the intervention. Caregiver, patient, and health system factors associated with participation in offered care management services were assessed through bivariate and multivariate regression analyses. RESULTS: Out of the 238 dyads, 9 were ineligible for this analysis, leaving data of 229 dyads in this sample. Of these, 185 dyads accepted offered care management services, and 44 dyads did not. Multivariate analyses showed that higher likelihood of acceptance of care management services was uniquely associated with cohabitation of caregiver and patient (p < 0.001), lesser severity of dementia (p = 0.03), and higher patient comorbidity (p = 0.03); it also varied across healthcare organization sites. CONCLUSIONS: Understanding factors that influence care management participation could result in increased adoption of successful programs to improve quality of care. Using these factors to revise both program design as well as program promotion may also benefit external validity of future quality improvement research trials.

"The System Doesn't Let Us in"-A Call for Inclusive COVID-19 Vaccine Outreach Rooted in Los Angeles Latinos' Experience of Pandemic Hardships and Inequities.

OBJECTIVE: Latino adults in Los Angeles have experienced disproportionate cases, deaths, and socioeconomic impacts from the COVID-19 pandemic. This qualitative study aimed to explore community perspectives on readiness for COVID-19 vaccination and to identify culturally tailored vaccine outreach strategies. METHODS: We conducted virtual focus groups with Los Angeles County Latino/a residents via Zoom between December 2020 to January 2021, as the first COVID-19 vaccines were receiving Emergency Use Authorization (EUA). Focus groups were facilitated in Spanish and English by bilingual members of the research team. Discussions were analyzed via Atlas.ti software using reflexive thematic analysis. RESULTS: Three focus groups (n = 15; four to six people each; two Spanish focus groups; one English) were conducted. Thematic findings centered on Latino COVID-19 vaccine equity: (1) Disproportionate infection risk due to essential worker status and socioeconomic burdens, misinformation, and familial or cultural tensions (2) Concerns for inequitable vaccine access due to immigration fears and limited healthcare access, and (3) A need for community-centered COVID-19 vaccine outreach and access. CONCLUSIONS: Our study on early Latino adult reactions to vaccine roll-out suggests the need for outreach strategies centering on validating community hardships, combating dis-/misinformation through trusted sources, and addressing socio-economic needs impacted by the pandemic.

Mechanisms for Community Health Worker Action on Patient-, Institutional-, and Community-Level Barriers to Primary Care in a Safety-Net Setting.

Medically and socially complex patients disproportionately face barriers to primary care, contributing to health inequities and higher health care costs. This study elicited perspectives on how community health workers (CHWs) act upon barriers to primary care in 5 patient (n = 25) and 3 CHW focus groups (n = 17). Participants described how CHWs acted on patient-level barriers through social support, empowerment, and linkages, and system-level barriers by enhancing care team awareness of patient circumstances, optimizing communication, and advocating for equitable treatment. Limitations existed for influencing entrenched community-level barriers. CHWs, focusing on patient preferences, motivators, and circumstances, intervened on multilevel barriers to primary care, including advocacy for equitable treatment. These mechanisms have implications for existing CHW conceptual models.

STOP COVID-19 CA: Community engagement to address the disparate impacts of the COVID-19 pandemic in California.

Objective: To describe the early activities and lessons of the Share, Trust, Organize, Partner COVID-19 California Alliance (STOP COVID-19 CA), the California awardee of the NIH-funded multi-state Community Engagement Alliance (CEAL) against COVID-19. The Alliance was established to ensure equity in Coronavirus-19 disease (COVID-19) research, clinical practice, and public health for communities most impacted by the COVID-19 pandemic. Study setting: The STOP COVID-19 CA Alliance network of 11 universities and affiliated partner community-based organizations (CBOs) across California. Study design: Mixed methods evaluation consisting of an analysis of activity (August 2020 to December 2021) detailed in reports submitted by community-academic teams and a survey (August 2021) of academic investigators and affiliated community-based organization (CBO) partners. Data collection: We summarized activities from the 11 community-academic teams' progress reports and described results from an online survey of academic investigators and CBO partners in the California Alliance. Principal findings: A review of progress reports (n = 256) showed that teams fielded surveys to 11,000 Californians, conducted 133 focus groups, partnered with 29 vaccine/therapeutics clinical trials, and led more than 300 town halls and vaccine events that reached Californians from communities disproportionately impacted by COVID-19. Survey responses from academic investigators and CBO partners emphasized the importance of learning from the successes and challenges of the California Alliance teams' COVID-19 initiatives. Both academic and CBO respondents highlighted the need for streamlined federal and institutional administrative policies, and fiscal practices to promote more effective and timely operations of teams in their efforts to address the numerous underlying health and social disparities that predispose their communities to higher rates of, and poor outcomes from, COVID-19. Conclusions: STOP COVID-19 CA represents a new and potentially sustainable statewide community engagement model for addressing health disparities in multiethnic/multicultural and geographically dispersed communities.

Using administrative databases to calculate Framingham scores within a large health care organization.

BACKGROUND AND PURPOSE: Framingham calculators are typically implemented in 1-on-1 settings to determine if a patient is at high risk for development of cardiovascular disease in the next 10 years. Because health care administrative datasets are including more clinical information, we explored how well administrative data-derived Framingham scores could identify persons who would have stroke develop in the next year. METHODS: Using a nested case-control design, we compared all 313 persons who had a first-time stroke at 5 Veterans Administration Medical Centers with a random sample of 25,361 persons who did not have a first-time stroke in 2008. We compared Framingham scores and risk using administrative data available at the end of 2007. RESULTS: Stroke patients had higher risk profile than controls: older age, higher systolic blood pressure and total cholesterol, more likely to have diabetes, cardiovascular disease, left ventricular hypertrophy, and more likely to use treatment for blood pressure (P<0.05). The mean Framingham generalized cardiovascular disease score (18.0 versus 14.5) as well as the mean Framingham stroke-specific score (13.2 versus 10.2) was higher for stroke cases than controls (both P<0.0001). The c-statistic for the generalized cardiovascular disease score was 0.68 (95% CI, 0.65-0.70) and for the stroke score was 0.64 (95% CI, 0.62-0.67). CONCLUSIONS: Persons who had a stroke develop in the next year had a worse Framingham risk profile, as determined by administrative data. Future studies should examine how to improve the stroke predictive tools and to identify the appropriate populations and uses for applying stroke risk predictive tools.

Neighborhood disadvantage and ischemic stroke: the Cardiovascular Health Study (CHS).

BACKGROUND AND PURPOSE: Neighborhood characteristics may influence the risk of stroke and contribute to socioeconomic disparities in stroke incidence. The objectives of this study were to examine the relationship between neighborhood socioeconomic status and incident ischemic stroke and examine potential mediators of these associations. METHODS: We analyzed data from 3834 whites and 785 blacks enrolled in the Cardiovascular Health Study, a multicenter, population-based, longitudinal study of adults ages≥65 years from 4 US counties. The primary outcome was adjudicated incident ischemic stroke. Neighborhood socioeconomic status was measured using a composite of 6 census tract variables. Race-stratified multilevel Cox proportional hazard models were constructed adjusted for sociodemographic, behavioral, and biological risk factors. RESULTS: Among whites, in models adjusted for sociodemographic characteristics, stroke hazard was significantly higher among residents of neighborhoods in the lowest compared with the highest neighborhood socioeconomic status quartile (hazard ratio, 1.32; 95% CI, 1.01-1.72) with greater attenuation of the hazard ratio after adjustment for biological risk factors (hazard ratio, 1.16; 0.88-1.52) than for behavioral risk factors (hazard ratio, 1.30; 0.99-1.70). Among blacks, we found no significant associations between neighborhood socioeconomic status and ischemic stroke. CONCLUSIONS: Higher risk of incident ischemic stroke was observed in the most disadvantaged neighborhoods among whites, but not among blacks. The relationship between neighborhood socioeconomic status and stroke among whites appears to be mediated more strongly by biological than behavioral risk factors.

Not Speaking the Same Language-Lower Portal Use for Limited English Proficient Patients in the Los Angeles Safety Net.

BACKGROUND: With the expansion of online patient portals linked to electronic health records in safety-net health care settings, we need more data on the use of these websites by patients with limited English proficiency (LEP) in order to guide their continued design, implementation, and evaluation as portals for the underserved. METHODS: Cross-sectional portal data for the Los Angeles County Department of Health Services, the second largest safety-net system in the nation. We examined differences in portal use across language (English vs. non-English/LEP), covering four years since implementation. RESULTS: Of 425,281 patients assigned to primary care as of March 2019, 55,190 (13%) unique portal enrollments were registered. Among 54,981 portal users, LEP users had lower adjusted odds of using an active portal function (e.g., medication refill) vs. English-speakers. CONCLUSIONS: Even among those registered to access portals, these websites are underused, particularly by LEP patients. All systems must facilitate use for these populations, especially for time-saving active functions, which can improve outcomes. Health systems must prioritize design/usability as a factor to counter LEP underuse.
