Treatment at safety-net hospitals is associated with delays in coil embolization in patients with subarachnoid hemorrhage
World neurosurgery, 2018•Elsevier
Background Successful endovascular management of aneurysmal subarachnoid
hemorrhage (aSAH) requires timely access to substantial resources. Prior studies suggest
an association between time to treatment and patient outcome. Patients treated at safety-net
hospitals are thought to be particularly vulnerable to disparities in access to interventions
that require substantial technologic resources. We hypothesized that patients with aSAH

Background
Successful endovascular management of aneurysmal subarachnoid hemorrhage (aSAH) requires timely access to substantial resources. Prior studies suggest an association between time to treatment and patient outcome. Patients treated at safety-net hospitals are thought to be particularly vulnerable to disparities in access to interventions that require substantial technologic resources. We hypothesized that patients with aSAH treated at safety-net hospitals are at greater risk for delayed access to endovascular treatment.
Methods
Adults undergoing endovascular coiling procedures between 2002 and 2011 in the Nationwide Inpatient Sample were included. Hospitals in the quartile with the highest proportion of Medicaid or uninsured patients were defined as safety-net hospitals. A multivariate model including patient-level and hospital-level factors was constructed to permit analysis of delays in endovascular treatment (defined as time to treatment >3 days).
Results
Analysis included 7109 discharges of patients with aSAH undergoing endovascular coil embolization procedures from 2002 to 2011. Median time to coil embolization in all patients was 1 day; 10.1% of patients waited >3 days until treatment. In multivariate analysis, patients treated at safety-net hospitals were more likely to have a prolonged time to coil embolization (odds ratio = 1.32, P < 0.01) compared with patients treated at low-burden hospitals.
Conclusions
After controlling for patient and hospital factors, individuals with aSAH treated at safety-net hospitals from 2002 to 2011 were more likely to have a delay to endovascular coil embolization than individuals treated at non–safety-net hospitals. This disparity could affect patient outcomes.
