OBJECTIVESafety-net hospitals deliver care to a substantial share of vulnerable patient populations and are disproportionately impacted by hospital payment reform policies. Complex elective procedures performed at safety-net facilities are associated with worse outcomes and higher costs. The effects of hospital safety-net burden on highly specialized, emergent, and resource-intensive conditions are poorly understood. The authors examined the effects of hospital safety-net burden on outcomes and costs after emergent neurosurgical intervention for ruptured cerebral aneurysms.METHODSThe authors conducted a retrospective analysis of the Nationwide Inpatient Sample (NIS) from 2002 to 2011. Patients ≥ 18 years old who underwent emergent surgical clipping and endovascular coiling for aneurysmal subarachnoid hemorrhage (SAH) were included. Safety-net burden was defined as the proportion of Medicaid and uninsured patients treated at each hospital included in the NIS database. Hospitals that performed clipping and coiling were stratified as low-burden (LBH), medium-burden (MBH), and high-burden (HBH) hospitals.RESULTSA total of 34,647 patients with ruptured cerebral aneurysms underwent clipping and 23,687 underwent coiling. Compared to LBHs, HBHs were more likely to treat black, Hispanic, Medicaid, and uninsured patients (p < 0.001). HBHs were also more likely to be associated with teaching hospitals (p < 0.001). No significant differences were observed among the burden groups in the severity of subarachnoid hemorrhage. After adjusting for patient demographics and hospital characteristics, treatment at an HBH did not predict in-hospital mortality, poor outcome, length of stay, costs, or likelihood of a hospital-acquired condition.CONCLUSIONSDespite their financial burden, safety-net hospitals provide equitable care after surgical clipping and endovascular coiling for ruptured cerebral aneurysms and do not incur higher hospital costs. Safety-net hospitals may have the capacity to provide equitable surgical care for highly specialized emergent neurosurgical conditions.

Object Endovascular coiling and surgical clipping are viable treatment options of cerebral aneurysms. Outcome data of these treatments in children are limited. The objective of this study was to determine hospital mortality and complication rates associated with surgical clipping and coil embolization of cerebral aneurysms in children, and to evaluate the trend of hospitals' use of these treatments. Methods The authors identified a cohort of children admitted with the diagnoses of cerebral aneurysms and aneurysmal subarachnoid hemorrhage from the Kids' Inpatient Database for the years 1998 through 2009. Hospital-associated complications and in-hospital mortality were compared between the treatment groups and stratified by aneurysmal rupture status. A multivariate regression analysis was used to identify independent variables associated with in-hospital mortality. The Cochrane-Armitage test was used to assess the trend of hospital use of these operations. Results A total of 1120 children were included in this analysis; 200 (18%) underwent aneurysmal clipping and 920 (82%) underwent endovascular coiling. Overall in-hospital mortality was higher in the surgical clipping group compared with the coil embolization group (6.09% vs 1.65%, respectively; adjusted odds ratio [OR] 2.52, 95% CI 0.97–6.53, p = 0.05). The risk of postoperative stroke or hemorrhage was similar between the two treatment groups (p = 0.86). Pulmonary complications and systemic infection were higher in the surgical clipping population (p < 0.05). The rate of US hospitals' use of endovascular coiling has significantly increased over the years included in this study (p < 0.0001). Teaching hospitals were associated with a lower risk of death (OR 0.13, 95% CI 0.03–0.46; p = 0.001). Conclusions Although both treatments are valid, endovascular coiling was associated with fewer deaths and shorter hospital stays than clip placement. The trend of hospitals' use of coiling operations has increased in recent years.

OBJECTIVEShunt-dependent hydrocephalus (SDHC) may arise after aneurysmal subarachnoid hemorrhage (aSAH) as CSF resorptive mechanisms are disrupted. Using propensity score analysis, the authors aimed to investigate which treatment modality, surgical clipping or endovascular treatment, is superior in reducing rates of SDHC after aSAH.METHODSThe authors’ multicenter SAH database, comprising 3 stroke centers affiliated with Kyoto University, Japan, was used to identify patients treated between January 2009 and July 2016. Univariate and multivariate analyses were performed to characterize risk factors for SDHC after aSAH. A propensity score model was generated for both treatment groups, incorporating relevant patient covariates to detect any superiority for prevention of SDHC after aSAH.RESULTSA total of 566 patients were enrolled in this study. SDHC developed in 127 patients (22%). On multivariate analysis, age older than 53 years, the presence of intraventricular hematoma, and surgical clipping as opposed to endovascular coiling were independently associated with SDHC after aSAH. After propensity score matching, 136 patients treated with surgical clipping and 136 with endovascular treatment were matched. Propensity score–matched cohorts exhibited a significantly lower incidence of SDHC after endovascular treatment than after surgical clipping (16% vs 30%, p = 0.009; OR 2.2, 95% CI 1.2–4.2). SDHC was independently associated with poor neurological outcomes (modified Rankin Scale score 3–6) at discharge (OR 4.3, 95% CI 2.6–7.3; p < 0.001).CONCLUSIONSSDHC after aSAH occurred significantly more frequently in patients who underwent surgical clipping. Strategies for treatment of ruptured aneurysms should be used to mitigate SDHC and minimize poor outcomes.

Abstract OBJECTIVE Endovascular coiling has been used increasingly as an alternative to neurosurgical clipping for treating subarachnoid hemorrhage secondary to aneurysm rupture. The aim of the present study was to provide a prospective, longitudinal investigation into cognitive function in patients with aneurysmal subarachnoid hemorrhage treated with either neurosurgical clipping or endovascular coiling. METHODS Twenty-three patients who were treated for aneurysmal subarachnoid hemorrhage at the National Hospital for Neurology and Neurosurgery in London, England, were recruited prospectively. Twelve patients who underwent surgical clipping were compared with a group of 11 patients who underwent endovascular coiling. All patients underwent a comprehensive, standardized neuropsychological assessment using the same battery of tests at the acute stage (within 2 wk after treatment). All patients who underwent coiling and 11 of the 12 patients who underwent clipping were reassessed at the post-acute long-term follow-up (6 mo) stage. RESULTS Group comparisons at the acute assessment revealed a significant difference favoring coiling patients on only one measure of verbal recall. However, there were no other significant differences between the groups at this stage. At the post-acute assessment, the clipped group performed better than the coiled group on measures of intellectual functioning (P &lt; 0.05), although no other differences were found on a range of cognitive tests. Intragroup comparisons between the acute and post-acute assessments found equivocal, significant improvements in measures of intellectual functioning, memory, executive functions, and speed of information processing in both groups of patients. CONCLUSION We argue that there are minimal differences in the long-term cognitive outcome between endovascular coiling and surgical clipping. In the acute phase after treatment, we suggest that coiled patients, having been spared neurosurgical intervention, may have a slightly better cognitive outcome than clipped patients. However, these differences level off and both groups of patients ultimately experience widespread improvement in cognitive functioning by the post-acute stage of recovery.

Abstract OBJECTIVE To assess the impact of vasospasm on costs, length of stay, and mortality among inpatients with aneurysmal subarachnoid hemorrhage. METHODS We combined hospital accounting and physician billing data for a consecutive cohort of 198 patients who underwent surgical clipping or endovascular coiling for subarachnoid hemorrhage repair. We considered patients with transcranial Doppler (TCD) velocity of 120 cm/s or greater in the middle cerebral artery to have TCD-defined vasospasm and patients with delayed ischemic neurological deficit to have symptomatic vasospasm. We compared outcomes of patients with TCD-defined vasospasm (n = 116) and those without (n = 73) and patients with symptomatic vasospasm (n = 62) and those without (n = 127), adjusting for demographic and clinical characteristics. RESULTS In adjusted analyses, the incremental cost attributable to TCD-defined vasospasm was 1.20 times higher (95% confidence interval, 1.06–1.36; P = .004) than for patients without TCD-defined vasospasm. Length of stay was an estimated 1.22 times longer for patients with TCD-defined vasospasm (95% CI, 1.07–1.39; P &lt; .01). For symptomatic vasospasm, adjusted costs were 1.27 times higher (95% CI, 1.12–1.43; P &lt; .001) and length of stay was an estimated 1.24 times longer (95% CI, 1.09–1.40; P &lt; .01) for patients with vasospasm than for those without. There was no significant relationship between either type of vasospasm and in-hospital mortality. CONCLUSION Patients with subarachnoid hemorrhage and TCD-defined or symptomatic vasospasm incur higher inpatient costs and longer hospital stays than those without vasospasm.

IntroductionPrior studies of aneurysmal subarachnoid hemorrhage (SAH) have shown that treatment at teaching institutions and decreased time to surgery are factors that correlate with improved patient outcome. We aimed to individually evaluate the effect of teaching institution treatment on rates of surgical clipping or endovascular coiling.MethodsPatients with SAH treated by either aneurysm clipping or coiling between 2002 and 2010 in the Nationwide Inpatient Sample were analyzed. Time to aneurysm treatment was dichotomized to >3 days or ≤3 days and evaluated by multivariable logistic regression modeling, controlling for patient and hospital covariates. Identified predictors for prolonged time to procedure were compared between the clipping and coiling populations.ResultsBetween 2002 and 2010 there were 90 684 SAH admissions with subsequent clipping and coiling procedures. Treatment at teaching hospitals was associated with faster time to clipping (OR 0.60, 95% CI 0.44 to 0.80, p=0.001) but not coiling procedures (p=0.66). Likewise, older age (≥80 years) was associated with delays to clipping (p<0.05) but not coiling procedures (p>0.05). Patients with delayed time to treatment were associated with increased rates of moderate to severe neurological disability.ConclusionsOlder patients with SAH and those treated at non-teaching hospitals were more likely to have delays to aneurysm clipping procedures. These associations were unique to open surgery as age and hospital teaching status did not affect time to coiling procedures.

The Impact

OBJECTIVE More than 10 years have passed since the two best-known clinical trials of ruptured aneurysms (International Subarachnoid Aneurysm Trial [ISAT] and Barrow Ruptured Aneurysm Trial [BRAT]) indicated that endovascular coiling (EC) was superior to surgical clipping (SC). However, in recent years, the development of surgical techniques has greatly improved; thus, it is necessary to reanalyze the impact of the differences in treatment modalities on the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). METHODS The authors retrospectively reviewed all aSAH patients admitted to their institution between January 2015 and December 2020. The functional outcomes at discharge and 90 days after discharge were assessed using the modified Rankin Scale (mRS). In-hospital complications, hospital charges, and risk factors derived from multivariate logistic regression were analyzed in the SC and EC groups after 1:1 propensity score matching (PSM). The area under the receiver operating characteristic curve was used to calculate each independent predictor’s prediction ability between treatment groups. RESULTS A total of 844 aSAH patients were included. After PSM to control for sex, aneurysm location, Hunt and Hess grade, World Federation of Neurosurgical Societies (WFNS) grade, modified Fisher Scale grade, and current smoking and alcohol abuse status, 329 patients who underwent SC were compared with 329 patients who underwent EC. Patients who underwent SC had higher incidences of unfavorable discharge and 90-day outcomes (46.5% vs 33.1%, p < 0.001; and 19.6% vs 13.8%, p = 0.046, respectively), delayed cerebral ischemia (DCI) (31.3% vs 20.1%, p = 0.001), intracranial infection (20.1% vs 1.2%, p < 0.001), anemia (42.2% vs 17.6%, p < 0.001), hypoproteinemia (46.2% vs 21.6%, p < 0.001), and pneumonia (33.4% vs 24.9%, p = 0.016); but a lower incidence of urinary tract infection (1.2% vs 5.2%, p = 0.004) and lower median hospital charges ($12,285 [IQR $10,399–$15,569] vs $23,656 [IQR $18,816–$30,025], p < 0.001). A positive correlation between the number of in-hospital complications and total hospital charges was indicated in the SC (r = 0.498, p < 0.001) and EC (r = 0.411, p < 0.001) groups. The occurrence of pneumonia and DCI, WFNS grade IV or V, and age were common independent risk factors for unfavorable outcomes at discharge and 90 days after discharge in both treatment modalities. CONCLUSIONS EC shows advantages in discharge and 90-day outcomes, in-hospital complications, and the number of risk factors but increases the economic cost on patients during their hospital stay. Severe in-hospital complications such as pneumonia and DCI may have a long-lasting impact on the prognosis of patients.
