Abstract
BACKGROUND Informal home care is prevalent among Mexican American stroke survivors, but data on the impact on caregivers are not available. The aim was to assess ethnic differences in informal stroke caregiving and caregiver outcomes at 90 days poststroke. METHODS Informal caregivers were recruited from the population-based Brain Attack Surveillance in Corpus Christi Project (2019-2023), conducted in a bi-ethnic community in Texas. Caregivers of community-dwelling stroke survivors who were not cognitively impaired and not employed by a formal caregiving agency were interviewed. Interviews included sociodemographics, dyad characteristics, Modified Caregiver Strain Index (range 0-26, higher more positive), Positive Aspects of Caregiving scale (range, 5-45, higher more), Patient Health Questionnaire-8 (range, 0-30, higher worse), and PROMIS (Patient-Reported Outcomes Measurement Information System)-10 physical (range, 16.2-67.7, higher better) and mental health (range, 21.2-67.6, higher better) summary scores. Stroke survivor data was from interviews and medical records. Propensity score methods were used to balance caregiver and patient factors among Mexican American and Non-Hispanic White caregivers by fitting a model with ethnicity of caregiver as the outcome and predictors being caregiver sociodemographics, patient-caregiver dyad characteristics, and patient sociodemographics and functional disability. Propensity scores were included as a covariate in regression models, considering the association between ethnicity and outcomes. RESULTS Mexican American caregivers were younger, more likely female, and more likely a child of the stroke survivor than Non-Hispanic White caregivers. Mexican American caregiver ethnicity was associated with less caregiver strain (β, -1.87 [95% CI, -3.51 to -0.22]) and depressive symptoms (β, -2.02 [95% CI, -3.41 to -0.64]) and more favorable mental health (β, 4.90 [95% CI, 2.49-7.31]) and positive aspects of caregiving (β, 3.29 [95% CI, 1.35-5.23]) but not associated with physical health. CONCLUSIONS Understanding the mechanisms behind more favorable caregiver outcomes in Mexican American people may aid in the design of culturally sensitive interventions to improve both caregiver and stroke survivor outcomes, potentially across all race and ethnic groups.

Abstract
BACKGROUND After stroke, Mexican American (MA) individuals have worse 90-day neurological, functional, cognitive, and quality of life outcomes and a higher prevalence of poststroke depression compared with non-Hispanic White (NHW) individuals. MA individuals receive more help through informal, unpaid caregiving than NHW individuals. We examined ethnic differences in needs identified by MA and NHW stroke caregivers. METHODS Caregivers were identified from the population-based BASIC study (Brain Attack Surveillance in Corpus Christi) in Nueces County, Texas from October 2019 to November 2021. Responses to the Caregiver Needs and Concerns Checklist were collected at 90-day poststroke to assess caregiver needs. Using the cross-sectional sample, prevalence scores and bivariate analyses were used to examine ethnic differences between Caregiver Needs and Concerns Checklist items. Linear regression was used to examine adjusted associations of ethnicity with the total average needs for each domain. Models were adjusted for patient and caregiver age and sex, caregiver education level, and employment status, patient insurance status, prestroke function, cognitive status, language, and functional outcome at 90 days, intensity and duration of caregiving, presence of other caregivers (paid/unpaid), and cohabitation of patient and caregiver. RESULTS A total of 287 were approached, and 186 stroke caregivers were included with a median age of 54.2 years and 80.1% being women caregivers: 74.3% MA and 25.7% NHW individuals. MA caregivers had significantly lower education ( CONCLUSIONS MA stroke caregivers have greater information needs compared with NHW caregivers and a greater number of needs overall. This information can help improve resources to help with poststroke recovery, improve caregiver well-being, and strengthen health equity.

Long-Term Psychological Distress Among Surrogate Decision Makers for Mexican American and Non-Hispanic White Patients With Severe Stroke. Neurology 2024; 102:e207960. [PMID: 38165320 PMCID: PMC10870740 DOI: 10.1212/wnl.0000000000207960] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 09/06/2023] [Indexed: 01/03/2024] Open
Abstract
BACKGROUND AND OBJECTIVES During acute hospitalizations, physicians often focus on the stroke patient and not family who may be traumatized by this sudden change to their loved one. We investigated long-term psychological distress among family surrogate decision makers for Mexican American (MA) and non-Hispanic White (NHW) severe stroke patients. Previous work in other diseases suggested worse psychological outcomes in MA than NHW caregivers. METHODS This was a population-based, prospective cohort study in Nueces County, TX. Stroke patient participants and their surrogate decision makers were enrolled soon after any stroke between April, 2016, and October, 2020, if surrogates had made decisions about life-sustaining treatments. Surrogates completed validated measures of posttraumatic stress, National Stressful Events Survey for Posttraumatic Stress Disorder Short Scale; anxiety, Generalized Anxiety Disorder-7; and depression, Patient Health Questionnaire-8 at discharge, 3, 6, and 12 months. Ethnic differences were assessed with multilevel linear mixed models, sequentially adjusted for prespecified patient and surrogate demographic, socioeconomic, and clinical covariates. RESULTS There were 301 family surrogates for 241 severe stroke patients. The mean follow-up was 315 days. High scores on measures of psychological distress ranged between 17% and 28% of surrogates. One or more high levels of the psychological outcomes were found in 17%-43% of surrogates; 2 or more were found in 12%-27%; and all 3 were found in 5%-16% of surrogates. All psychological outcomes were worse among MAs on unadjusted analyses. In fully adjusted models, posttraumatic stress remained worse among MAs (0.36, 95% CI 0.17-0.56); ethnic differences were attenuated and no longer significant in the final model for anxiety (0.59, 95% CI -0.55 to 1.74) and depression (0.97, 95% CI -0.25 to 2.19). The trajectory for depression did differ by ethnicity (interaction p = 0.03), with depression score improving more rapidly over time among NHWs than MAs. Advance care plans did not seem to confound any ethnic differences. DISCUSSION Psychological distress is common among family surrogate decision makers in the year after stroke and may be worse among MAs. Efforts are needed to support family members of all ethnic groups after severe stroke.

Abstract
INTRODUCTION We studied racial differences in post-stroke outcomes using a prospective, population-based cohort of stroke survivors as part of the Brain Attack Surveillance in Corpus Christi (BASIC) project. METHODS Neurologic (NIHSS, range of 0-42, higher scores are worse), functional (ADLs/IADLs, range 1-4, higher scores are worse), and cognitive (3MSE, range 0-100, higher scores are better) outcomes were measured 90 days after stroke. Cox proportional hazards and negative binomial linear regression models were used to examine the associations between race and 90-day all-cause mortality and NIHSS, respectively, whereas linear regression was used for ADLs/IADLs and 3MSE scores. Covariates included demographics, initial NIHSS, comorbidities, prior stroke history, tPA treatment status, pre-stroke disability, and pre-stroke cognition. The mortality model was also adjusted for DNR status. RESULTS At 90 days post-stroke, Black American individuals (BAs) (n = 122) had a median (IQR) NIHSS of 2 (1,6) compared to NIHSS of 1 (0,3) in non-Hispanic White American individuals (NHWs) (n = 795). BAs had a median (IQR) ADL/IADL score of 2.41 (1.50, 3.39) compared to 2.00 (1.27, 2.95) in NHWs. BAs scored a median of 84 (75, 92) on the 3MSE compared to NHWs' score of 91.5 (83, 96). Death occurred in 23 (8%) of BAs and 268 (15%) of NHWs within 90 days among those who participated in baseline. After adjustment for covariates, functional outcomes at 90 days were worse in BAs compared to NHWs, with 15.8% (95% CI=5.2, 26.4) greater limitations in ADLs/IADLs and 43.9% (95% CI=12.0, 84.9) greater severity of stroke symptoms. Cognition at 90 days was 6.5% (95% CI=2.4, 10.6) lower in BAs compared to NHWs. BAs had a 35.4% lower (95% CI=-9.8, 61.9) hazard rate of mortality than NHWs. CONCLUSIONS In this prospective, population-based community sample, BAs had worse neurologic, functional and cognitive outcomes at 90 days compared to NHWs. Future research should investigate how social determinants of health including structural racism, neighborhood factors and access to preventive and recovery services influences these racial disparities.

Abstract
BACKGROUND The aim of this study was to characterize change in sleep-disordered breathing severity in the year following stroke, overall, and by ethnicity, within the population-based Brain Attack Surveillance in Corpus Christi Project. METHODS First-ever ischemic strokes (n=414) were ascertained by active and passive surveillance and validated by stroke-trained physicians. Patients with stroke were invited to participate in portable sleep apnea testing (ApneaLink Plus) at baseline and 3, 6, and 12 months poststroke. Sleep-disordered breathing severity was assessed by the respiratory event index (apneas and hypopneas/hour of recording). The component obstructive apnea index and central apnea index were also assessed. Time and ethnicity effects on outcomes, as well as ethnic differences in time effects, were analyzed using generalized estimating equations with multivariable adjustment for confounding factors. RESULTS Mean age (n=414) was 63.9 years (SD=10.9); 68.4% were Mexican American. Baseline mean respiratory event index, obstructive apnea index, and central apnea index were 21.3 (SD=16.6), 8.6 (SD=11.5), and 1.5 (SD=3.2), respectively. There was no time effect on respiratory event index (P=0.35) but obstructive apnea index increased over time (P<0.01). Averaged over follow-up, respiratory event index and obstructive apnea index were significantly higher in Mexican American than non-Hispanic White persons. No ethnic difference in the time effect was found for either outcome. For central apnea index, there was an ethnicity-time interaction (P=0.01) such that central apnea index increased in non-Hispanic White but did not change in Mexican American persons. CONCLUSIONS Sleep-disordered breathing severity was significant and stable for most individuals in the year after stroke. These results do not confirm previous reports of diminishing sleep-disordered breathing severity over time after stroke and would support early assessment and treatment where indicated.
