Background: Previous studies have not evaluated the impact of illness severity and postrupture procedures in the cost of care for intracranial aneurysms. We hypothesize that the severity of aneurysm rupture and the aggressiveness of postrupture interventions play a role in cost. Methods: The Value Driven Outcomes database was used to assess direct patient cost during the treatment of ruptured intracranial aneurysm with clipping, coiling, and Pipeline flow diverters. Results: One hundred ninety-eight patients (mean age 52.8 ± 14.1 years; 40.0% male) underwent craniotomy (64.6%), coiling (26.7%), or flow diversion (8.6%). Coiling was 1.4× more expensive than clipping (p =.005) and flow diversion was 1.7× more expensive than clipping (p <.001). More severe illness as measured by American Society of Anesthesia, Hunt/Hess, and Fisher scales incurred higher costs than less severe illness (p <.05). Use of a lumbar drain protocol to reduce subarachnoid hemorrhage and use of an external ventricular drain to manage intracranial pressure were associated with reduced (p =.05) and increased (p <.001) total costs, respectively. Patients with severe vasospasm (p <.005), those that received shunts (p <.001), and those who had complications (p <.001) had higher costs. Multivariate analysis showed that procedure type, length of stay, number of angiograms, vasospasm severity, disposition, and year of treatment were independent predictors of cost. Conclusions: These results show for the first time that disease and vasospasm severity and intensity of treatment directly impact the cost of care for patients with aneurysms in the USA. Strategies to alter these variables may prove important for cost reduction. [ABSTRACT FROM AUTHOR]

Health care costs comprise a substantial portion of total national expenditure. Although interest in cost-effectiveness analysis in neurosurgery has increased, there has been little cross-comparison of neurosurgical procedures. The aim of this study was to compare costs across elective neurosurgical procedures to understand whether drivers of cost differ. The Value Driven Outcomes database was used to evaluate treatment costs for resection of vestibular schwannoma, intracranial meningioma, gliomas, and pituitary adenoma; anterior cervical discectomy and fusion and lumbar spinal fusion; and aneurysm treatment. A total of 1997 patients (mean age 54.6 ± 14.5 years; 45.2% male) were evaluated. The mean length of stay (LOS) was 4.0 ± 4.4 days. For cases involving hardware implantation, including spine fusion or aneurysm treatment, supplies and implants (49.1%) accounted for the largest fraction of costs followed by facility costs (37.9%). For cases that did not involve hardware, including tumor cases, facility costs (63.9%) were the largest fraction, followed by supplies and implants (16.2%). Aneurysm treatment and lumbar fusion were 1.5–3 times more costly than cranial tumor resection and anterior cervical discectomy and fusion per patient. Multivariate linear regression demonstrated that LOS (β = 0.7, P = 0.0001) and patient treatment type (β = 0.2, P = 0.0001) had the greatest effect on costs. LOS correlated with cost differently depending on case type; its effect was largest for patients with meningioma and smallest for patients with vestibular schwannoma. Costs across time increased similarly for all case types. Costs for neurosurgical procedures vary widely depending on treatment type and correlated directly with LOS. Strategies to reduce cost may require different approaches depending on procedure type. [ABSTRACT FROM AUTHOR]
