Abstract

BACKGROUND: Sparse data exist on socioeconomic disparities among patients treated for aneurysmal subarachnoid hemorrhage (aSAH). The authors analyzed factors possibly influencing patient outcomes, including having a primary care physician (PCP) at admission, family/caregiver support, a foreign language barrier, primary payer status, and race. METHODS: Socioeconomic data were abstracted for patients treated endovascularly or microsurgically for aSAH at a single center (January 1, 2014-July 31, 2019). Binary logistic regression analyses were used to identify independent predictors of an unfavorable outcome (modified Rankin Scale [mRS] score >2) and for predictive modeling. RESULTS: Among 422 patients, the median (interquartile range) follow-up was 2 (1-23) months. Lack of caregiver support was the only socioeconomic factor associated with an unfavorable outcome at discharge. Independent predictors of mRS score >2 at last follow-up included baseline markers of disease severity (P ≤ 0.03), nonwhite race (OR, 1.69; P = 0.047), lack of caregiver support (OR, 5.55; P = 0.007), and lack of a PCP (OR, 1.96; P = 0.007). Adjusting for follow-up mediated the effects of race and PCP, although caregiver support remained significant and PCP was associated with a lower mortality risk independent of follow-up (OR, 0.51; P = 0.047). Predischarge socioeconomic factors, alongside disease severity, predicted a follow-up mRS score >2 with excellent discrimination (area under the receiver operating curve, 0.81; 95% CI, 0.77-0.86). CONCLUSIONS: At a large, urban, comprehensive stroke center, patients with PCPs, caregiver support, and white race had significantly better long-term outcomes after aSAH. These results reflect disparities in access to healthcare after aSAH for vulnerable populations with extensive lifetime needs.
