Abstract TP103: Association Between Neighborhood-Level Disadvantage and Patient-Reported Mental Health Outcomes in Intracerebral Hemorrhage Survivors

Abstract

Introduction: The influence of social determinants of health (SDH) is well-documented across a range of medical conditions and health outcomes. Less clear is the impact of SDH on patient-reported outcomes, particularly mental health outcomes, in intracerebral hemorrhage (ICH). This study examines the association between the Area Deprivation Index (ADI), a measure of neighborhood-level disadvantage, and self-reported health outcomes in ICH survivors. Methods: This investigation is nested within the REDUCE clinical trial, an ongoing, randomized trial comparing standard-of-care to spironolactone-containing hypertension regimens in ICH survivors. Participants complete the PROMIS Global Health survey at baseline. Global Mental Health (GMH) and Global Physical Health (GPH) scores are standardized to t-scores (GMH 21.2-67.6; GPH 16.2-67.7) around a reference population mean (50 ± 10). ADI uses elements of income, education, employment, and housing quality to assign a composite score (1-100), with a higher score signifying greater disadvantage. Patients were grouped into tertiles based on ADI. GMH and GPH scores were analyzed against the reference mean via a one-sample t-test and across tertiles with a one-way ANOVA. Bivariable linear regression examined ADI as a continuous variable. Multivariable models adjusted for sex, age, race, ethnicity, ICH to baseline interval, and baseline mRS. Results: Fifty patients were included in the analysis. Those in the third, most disadvantaged, tertile had significantly lower GMH scores (39.5 ± 8.17) than the reference population (p<0.001), the first tertile (54.10 ± 10.20, p<0.001), and the second tertile (50.4 ± 8.90, p=0.003). In multivariable analysis, these differences remained significant (T3 vs. T1, B= -18.31, p<0.001; T3 vs. T2, B= -14.67, p<0.001). Further, ADI as a continuous variable was significantly associated with GMH scores in bivariable (B= -0.22, p<0.001) and multivariable analysis (B= -0.23, p=0.005). No significant relationship was found between ADI and GPH. Conclusions: Higher ADI is associated with worse patient-reported mental health outcomes after ICH. Neighborhood disadvantage, and its constituting factors, should be considered in reporting post-ICH patient care and outcomes.
