PurposeTo compare aneurysmal subarachnoid hemorrhage (aSAH) outcomes between high- and low-volume referral centers with dedicated neurosciences critical care units (NCCUs) and shared neurosurgical, endovascular, and neurocritical care practitioners.Materials And MethodsProspectively collected data of aSAH patients admitted to 2 institutional NCCUs were reviewed. NCCU A is a 22-bed unit staffed 24/7 with overnight in-house NCCU fellow and resident coverage. NCCU B is a 14-bed unit with home call by NCCU attending/fellow and in-house residents.ResultsA total of 161 aSAH patients (27%) were admitted to NCCU B compared with 447 at NCCU A (73%). Among factors that independently impacted hospital mortality, there were no differences in baseline characteristics: mean age (A: 53.5 ± 14.1 years, B: 53.1 ± 13.6 years), poor grade Hunt and Hess (A: 28.2%, B: 26.7%), presence of multiple medical comorbidities (A: 28%, B: 31.1%), and associated cocaine use (A: 11.6%, B: 14.3%). There was no significant difference in hospital mortality (A: 17.9%, B: 18%), poor functional outcome (A: 30%, B: 25.4%), aneurysm rerupture (A: 2.8%, B: 2.4%), or delayed cerebral ischemia (A: 14.1%, B: 16.1%).ConclusionsThe noninferior outcomes at the lower SAH volume center suggests that provider expertise, not patient volume, is critical to providing high-quality specialized care.Copyright © 2015 Elsevier Inc.
