Item Deriving Place of Residence, Modified Rankin Scale, and EuroQol-5D Scores from the Medical Record for Stroke Survivors(Karger, 2021) Sucharew, Heidi; Kleindorfer, Dawn; Khoury, Jane C.; Alwell, Kathleen; Haverbusch, Mary; Stanton, Robert; Demel, Stacie; De Los Rios La Rosa, Felipe; Ferioli, Simona; Jasne, Adam; Mistry, Eva; Moomaw, Charles J.; Mackey, Jason; Slavin, Sabreena; Star, Michael; Walsh, Kyle; Woo, Daniel; Kissela, Brett M.; Neurology, School of MedicineIntroduction: We sought to determine the feasibility and validity of estimating post-stroke outcomes using information available in the electronic medical record (EMR) through comparison with outcomes obtained from telephone interviews. Methods: The Greater Cincinnati Northern Kentucky Stroke Study is a retrospective population-based epidemiology study that ascertains hospitalized strokes in the study region. As a sub-study, we identified all ischemic stroke patients who presented to a system of 4 hospitals during the study period 1/1/2015–12/31/2015 and were discharged alive. Enrolled subjects (or proxies for cognitively-disabled patients) were contacted by telephone at 3 and 6 months post-stroke to determine current place of residence and two functional outcomes—the modified Rankin Score (mRS) and the EuroQol (EQ-5D). Concurrently, the lead study coordinator, blinded to the telephone assessment outcomes, reviewed all available EMRs to estimate outcome status. Agreement between outcomes estimated from the EMR with “gold-standard” data obtained from telephone interviews was analyzed using the kappa statistic or interclass correlation (ICC), as appropriate. For each outcome, EMR-determined results were evaluated for added value beyond the information readily available from the stroke hospital stay. Results: Of 381 ischemic strokes identified, 294 (median [IQR] age 70 [60–79] years, 4% black, 52% female) were interviewed post-stroke. Agreement between EMR and telephone for 3-month residence was very good (kappa=0.84, 95% CI 0.74–0.94), good for mRS (weighted kappa=0.75, 95% CI 0.70–0.80), and good for EQ-5D (ICC=0.74, 95% CI 0.68–0.79). Similar results were observed at 6 months post stroke. At both 3 and 6 months post stroke, EMR-determined outcomes added value in predicting the gold standard telephone results beyond the information available from the stroke hospitalization; the added fraction of new information ranged from 0.25 to 0.59. Conclusions: Determining place of residence, mRS, and EQ-5D outcomes derived from information recorded in the EMR post-stroke, without patient contact, is feasible and has good agreement with data obtained from direct contact. However, we note that the level of agreement for mRS and EQ-5D was higher for proxy interviews and that the EMR often reflects health care providers’ judgments that tend to overestimate disability and underestimate quality of life.Item Racial Disparities in Stroke Recurrence: A Population-Based Study(Wolters Kluwer, 2022) Robinson, David Joseph; Stanton, Robert; Sucharew, Heidi; Alwell, Kathleen; Haverbusch, Mary; De Los Rios La Rosa, Felipe; Ferioli, Simona; Coleman, Elisheva; Jasne, Adam; Mackey, Jason; Star, Michael; Mistry, Eva A.; Demel, Stacie; Slavin, Sabreena; Walsh, Kyle; Woo, Daniel; Kissela, Brett; Kleindorfer, Dawn O.; Neurology, School of MedicineBackground and objective: There are significant racial disparities in stroke in the United States, with Black individuals having a higher risk of incident stroke even when adjusted for traditional stroke risk factors. It is unknown whether Black individuals are also at a higher risk of recurrent stroke. Methods: Over an 18-month period spanning 2014-2015, we ascertained index stroke cases within the Greater Cincinnati/Northern Kentucky population of 1.3 million. We then followed up all patients for 3 years and determined the risk of recurrence. Multivariable survival analysis was performed to determine the effect of Black race on recurrence. Results: There were 3,816 patients with index stroke/TIA events in our study period, and 476 patients had a recurrent event within 3 years. The Kaplan-Meier estimate of 3-year recurrence rate was 15.4%. Age-adjusted and sex-adjusted stroke recurrence rate was higher in Black individuals (HR 1.34, 95% CI 1.1-1.6; p = 0.003); however, when adjusted for traditional stroke risk factors including hypertension, diabetes, smoking status, age, and left ventricular hypertrophy, the association between Black race and recurrence was significantly attenuated and became nonsignificant (HR 1.1, 95% CI 0.9-1.36, p = 0.32). At younger ages, Black race was more strongly associated with recurrence, and this effect may not be fully attenuated by traditional stroke risk factors. Discussion: Recurrent stroke was more common among Black individuals, but the magnitude of the racial difference was substantially attenuated and became nonsignificant when adjusted for traditional stroke risk factors. Interventions targeting these risk factors could reduce disparities in stroke recurrence.
