    IntroductionWe sought to analyze the rate of utilization of methods of cerebrospinal fluid diversion over time in a nationally representative cohort of patients admitted with aneurysmal subarachnoid hemorrhage (aSAH).MethodsThe Nationwide Inpatient Sample was queried for patients admitted with aSAH from 2006 to 2018. Patients who received external ventricular drainage (EVD), lumbar drainage, ventriculoperitoneal shunt (VPS), and cerebral angiography were then identified. A Cochrane-Armitage test was conducted to assess the linear trend of proportions of EVD, lumbar drains, VPS, and mean cerebral angiograms per admission. Four regression analyses were conducted to infer the association of baseline variables to EVD, lumbar drain, VPS, and mean number of cerebral angiographies.ResultsA total of 133,567 admissions were identified from 2006-2018 involving aSAH. Of these, 41.82% received EVD, 6.22% received lumbar drainage, 10.58% received VPS, and 75.03% had cerebral angiograms. There was an average upward trend of 1.57% in annual EVD utilization, downward trend of -0.28% in utilization of lumbar drainage, no changes in VPS utilization, and an upward trend of 0.04 angiograms per year (P < 0.001). There was a higher proportion of Black patients treated with EVD and VPS in both urban teaching hospitals and large hospitals.ConclusionsOur results show the temporal trends in utilization of temporary and permanent methods of cerebrospinal fluid diversion and catheter cerebral angiography among patients with aSAH in the United States. The underutilization of VPS following EVD and the differences in EVD and VPS utilization depending on race and hospital size deserve further exploration.Copyright © 2022 Elsevier Inc.
