Objectives: Survivors of intracerebral haemorrhage (ICH) are at high risk of incident depression, which is modified by social determinants of health (SDOH) and associated with worse functional outcomes. We sought to determine the role of prestroke SDOH in depression incidence after ICH to better characterise post-ICH outcomes.
Study design: We analysed data from a cohort study of ICH survivors without prestroke depression, presenting at Massachusetts General Hospital between 2006 and 2017. We collected information from electronic health records (EHR), follow-up interviews and CT/MRI. The relationship between social vulnerability, air quality and post-ICH depression incidence within 12 months of acute haemorrhage was investigated using logistic regression models that also included EHR and CT/MRI information as predictors.
Results: Participants were 576 survivors, median age of 72 (IQR=61-81), 317 (55%) self-reported as male and 482 (84%) as white. 204 (35%) were diagnosed with depression within 12 months of ICH. Hospital admission longer than 1 week (OR 1.80, 95% CI 1.08 to 3.00), cerebral amyloid angiopathy (CAA) burden (OR 1.45, 95% CI 1.25 to 1.68) and social vulnerability (OR 3.03, 95% CI 1.49 to 6.19) were associated with depression incidence post-ICH.
Conclusions: In addition to CAA burden and patient location 1-week post-ICH, social vulnerability was independently associated with depression among ICH survivors. Our findings suggest that social vulnerability influences ICH outcomes. Future studies should investigate how poststroke clinical care interventions can address SDOH effects to reduce incident depression and improve outcomes among ICH survivors.
