Racial disparities in post-stroke functional outcomes in young patients with ischemic stroke.

BACKGROUND AND PURPOSE: Recent studies show rising incidence of stroke in the young, for which risk factors are not well characterized. There is evidence of increased risk in certain racial and ethnic groups. We assessed racial differences in risk factors, stroke etiology, and outcomes among young stroke patients. METHODS: Using data from our inpatient registry for ischemic stroke, we reviewed patients aged 18-50 who were admitted 01/2013 to 04/2018. Race/ethnicity were characterized as non-Hispanic White (NHW), non-Hispanic Black (NHB), Hispanic (HIS). For univariate comparisons Chi-square and Kruskal-Wallis tests were performed as appropriate. Multivariable logistic regression was used to assess impact of race on day seven modified Rankin score (mRS). RESULTS: Among 810 patients with race and outcome data who were admitted in the study period, median age was 43, 57.1% were male, and 36.5% NHW, 43.2% NHB, 20.2% HIS. History of hypertension (HTN), type II diabetes (DM II), smoking, heart failure (CHF), prior stroke, and end-stage renal disease varied significantly by race. Compared to NHW, NHB had higher odds of HTN (OR 2.28, 1.65-3.15), CHF (OR 2.17, 1.06-4.46), and DM II 1.92 (1.25-2.94) while HIS had higher odds of DM II (OR 2.52, 1.55-4.10) and lower odds of smoking (OR 0.56, 0.35-0.90). Arrival NIHSS was higher in NHB, but etiology and rates of tpA treatment and thrombectomy did not vary by race. Compared to NHW patients, NHB (OR 0.50 CI (0.31-0.78)) and HIS (OR 0.37 CI (0.21-0.67)) were less likely to have good functional outcome (mRS <2) at day 7 in adjusted analyses. CONCLUSIONS: In this study, there was a higher prevalence of several modifiable risk factors in NHB and HIS young stroke patients and early functional outcome was worse in these groups. Our study suggests a need for targeted prevention efforts for younger populations at highest risk for stroke.

Inequities in Telemedicine Use Among Patients With Stroke and Cerebrovascular Diseases: A Tricenter Cross-sectional Study.

Background and Objectives: In response to the COVID-19 pandemic, outpatient stroke care delivery was rapidly transformed to outpatient evaluation through video (VTM) and telephone (TPH) telemedicine (TM) visits around the world. We sought to evaluate the sociodemographic differences in outpatient TM use among stroke patients. Methods: We conducted a retrospective chart review of outpatients evaluated at 3 tertiary stroke centers in the early period of the pandemic, 3/16/2020 through 7/31/2020. We compared the use of TM by patient characteristics including age, sex, race/ethnicity, insurance status, stroke type, patient type, and site. The association between TM use and patient characteristics was measured using the relative risk (RR) from a modified Poisson regression, and site-specific effects were controlled using a multilevel analysis. Results: A total of 2,024 visits were included from UTHealth (n = 878), MedStar Health (n = 269), and Columbia (n = 877). The median age was 64 [IQR 52-74] years, and 53% were female. Approximately half of the patients had private insurance, 36% had Medicare, and 15% had Medicaid. Two-thirds of the visits were established patients. TM accounted for 90% of total visits, and the use of TM over office visits was primarily associated with site, not patient characteristics. TM utilization was associated with Asian and other/unknown race. Among TM users, older age, Black race, Hispanic ethnicity, and Medicaid insurance were associated with lower VTM use. Black (aRR 0.88, 95% CI 0.86-0.91, p < 0.001) and Hispanic patients (aRR 0.92, 95% CI 0.87-0.98, p = 0.005) had approximately 10% lower VTM use, while Asian patients (aRR 0.98, 95% CI 0.89-1.07, p = 0.59) had similar VTM use compared with White patients. Patients with Medicaid were less likely to use VTM compared with those with private insurance (aRR 0.86, 95% CI 0.81-0.91, p < 0.001). Discussion: In our diverse cohort across 3 centers, we found differences in TM visit type by race and insurance early during the COVID-19 pandemic. These findings suggest disparities in VTM access across different stroke populations. As VTM remains an integral part of outpatient neurology practice, steps to ensure equitable access are essential.

Caregiver Burden and Associated Factors Among Informal Caregivers of Stroke Survivors.

BACKGROUND: Informal caregiving of stroke survivors often begins with intensity compared with the linear caregiving trajectories in progressive conditions. Informal caregivers of stroke survivors are often inadequately prepared for their caregiving role, which can have detrimental effects on their well-being. A greater depth of understanding about caregiving burden is needed to identify caregivers in most need of intervention. The purpose of this study was to examine caregiver burden and associated factors among a cohort of informal caregivers of stroke survivors. METHODS: A cross-sectional study of 88 informal caregivers of stroke survivors was completed. Caregiver burden was determined with the Zarit Burden Interview, caregiver depressive symptoms were measured with the Patient Health Questionnaire-9, and stroke survivor functional disability was assessed with the Barthel Index. Ordinal logistic regression was used to identify independent factors associated with caregiver burden. RESULTS: Forty-three informal caregivers (49%) reported minimal or no caregiver burden, 30 (34%) reported mild to moderate caregiver burden, and 15 (17%) reported moderate to severe caregiver burden. Stroke survivor functional disability was associated with informal caregiver burden (P = .0387). The odds of having mild to moderate caregiver burden were 3.7 times higher for informal caregivers of stroke survivors with moderate to severe functional disability than for caregivers of stroke survivors with no functional disability. The presence of caregiver depressive symptoms was highly correlated with caregiver burden (P < .001). CONCLUSION: Caregivers of stroke survivors with functional disabilities and caregivers experiencing depressive symptoms may have severer caregiver burden. Trials of interventions aimed at decreasing informal caregiver burden should consider the potential impact of stroke survivors' functional disability and the presence of depressive symptoms.
