Abstract
BACKGROUND Moyamoya is a chronic occlusive cerebrovascular disease of unknown etiology causing neovascularization of the lenticulostriate collaterals at the base of the brain. Although revascularization surgery is the most effective treatment for moyamoya, there is still no consensus on the best surgical treatment modality as different studies provide different outcomes. OBJECTIVE In this large case series, we compare the outcomes of direct (DR) and indirect revascularisation (IR) and compare our results to the literature in order to reflect on the best revascularization modality for moyamoya. METHODS We conducted a multicenter retrospective study in accordance with the Strengthening the Reporting of Observational studies in Epidemiology guidelines of moyamoya affected hemispheres treated with DR and IR surgeries across 13 academic institutions predominantly in North America. All patients who underwent surgical revascularization of their moyamoya-affected hemispheres were included in the study. The primary outcome of the study was the rate of symptomatic strokes. RESULTS The rates of symptomatic strokes across 515 disease-affected hemispheres were comparable between the two cohorts (11.6% in the DR cohort vs 9.6% in the IR cohort, OR 1.238 (95% CI 0.651 to 2.354), p=0.514). The rate of total perioperative strokes was slightly higher in the DR cohort (6.1% for DR vs 2.0% for IR, OR 3.129 (95% CI 0.991 to 9.875), p=0.052). The rate of total follow-up strokes was slightly higher in the IR cohort (8.1% vs 6.6%, OR 0.799 (95% CI 0.374 to 1.709) p=0.563). CONCLUSION Since both modalities showed comparable rates of overall total strokes, both modalities of revascularization can be performed depending on the patient's risk assessment.

Abstract
INTRODUCTION There is sufficient scientific literature that demonstrates favorable outcomes using the minimally invasive technique of middle meningeal artery embolization (MMAE) for the treatment of chronic subdural hematomas (cSDH). The authors evaluate the outcomes of 35 consecutive patients treated with MMAE, both with and without adjuvant surgical drainage (ASD), in an attempt to identify variables that may affect the outcome of patients treated with MMAE for cSDH. METHODS A multivariate retrospective analysis was performed on patients who received MMAE for cSDH, including age, size of cSDH, ASD, presence of unilateral or bilateral collections, and use of anticoagulants. RESULTS Twenty patients underwent MMAE with planned ASD, while 15 patients had MMAE only; these groups had an average cSDH size reduction (measured at its greatest width) of 74% and 69% of cSDH, respectively. Of the 15 patients who were initially treated only with MMAE, three (20%) required a rescue craniotomy. Twenty patients (57%) who had initially presented while receiving oral anticoagulants had an average of 71% size reduction with ASD compared to 74% reduction in those without ASD. Patients not using anticoagulants had an 84% and 78% average reduction in size, respectively. Twelve patients presented with bilateral cSDH; patients who received ASD had an average size reduction of 58%; those without ASD had 63%. Patients with unilateral cSDH had 85% and 83% reduction in size, respectively. CONCLUSION Middle meningeal artery embolization, with or without ASD, can be a useful alternative or adjunct to standard surgical treatment for cSDH. Our study found that only three of 35 patients (9%) treated with this method required any further surgical intervention. No patient who received ASD had a recurrence of their cSDH. Further investigation, including prospective randomized studies, would be useful to better identify which patients can benefit and variables that impact the outcome of patients undergoing MMAE.

Abstract
BACKGROUND AND PURPOSE Flow diversion has established as standard treatment for intracranial aneurysms, the Surpass Streamline is the only FDA-approved braided cobalt/chromium alloy implant with 72-96 wires. We aimed to determine the safety and efficacy of the Surpass in a post-marketing large United States cohort. MATERIALS AND METHODS This is a retrospective multicenter study of consecutive patients treated with the Surpass for intracranial aneurysms between 2018 and 2021. Baseline demographics, comorbidities, and aneurysm characteristics were collected. Efficacy endpoint included aneurysm occlusion on radiographic follow-up. Safety endpoints were major ipsilateral ischemic stroke or treatment-related death. RESULTS A total of 277 patients with 314 aneurysms were included. Median age was 60 years, 202 (73%) patients were females. Hypertension was the most common comorbidity in 156 (56%) patients. The most common location of the aneurysms was the anterior circulation in 89% (279/314). Mean aneurysm dome width was 5.77 ± 4.75 mm, neck width was 4.22 ± 3.83 mm, and dome/neck ratio was 1.63 ± 1.26. Small-sized aneurysms were 185 (59%). Single device was used in 94% of the patients, mean number of devices per patient was 1.06. At final follow-up, complete obliteration rate was 81% (194/239). Major stroke and death were encountered in 7 (3%) and 6 (2%) cases, respectively. CONCLUSION This is the largest cohort study using a 72-96 wire flow diverter. The Surpass Streamline demonstrated a favorable safety and efficacy profile, making it a valuable option for treating not only large but also wide-necked small and medium-sized intracranial aneurysms.

Abstract
Background and purpose Previous studies suggest that mechanisms and outcomes in patients with COVID‐19‐associated stroke differ from those in patients with non‐COVID‐19‐associated strokes, but there is limited comparative evidence focusing on these populations. The aim of this study, therefore, was to determine if a significant association exists between COVID‐19 status with revascularization and functional outcomes following thrombectomy for large vessel occlusion (LVO), after adjustment for potential confounding factors. Methods A cross‐sectional, international multicenter retrospective study was conducted in consecutively admitted COVID‐19 patients with concomitant acute LVO, compared to a control group without COVID‐19. Data collected included age, gender, comorbidities, clinical characteristics, details of the involved vessels, procedural technique, and various outcomes. A multivariable‐adjusted analysis was conducted. Results In this cohort of 697 patients with acute LVO, 302 had COVID‐19 while 395 patients did not. There was a significant difference (p < 0.001) in the mean age (in years) and gender of patients, with younger patients and more males in the COVID‐19 group. In terms of favorable revascularization (modified Thrombolysis in Cerebral Infarction [mTICI] grade 3), COVID‐19 was associated with lower odds of complete revascularization (odds ratio 0.33, 95% confidence interval [CI] 0.23–0.48; p < 0.001), which persisted on multivariable modeling with adjustment for other predictors (adjusted odds ratio 0.30, 95% CI 0.12–0.77; p = 0.012). Moreover, endovascular complications, in‐hospital mortality, and length of hospital stay were significantly higher among COVID‐19 patients (p < 0.001). Conclusion COVID‐19 was an independent predictor of incomplete revascularization and poor functional outcome in patients with stroke due to LVO. Furthermore, COVID‐19 patients with LVO were more often younger and had higher morbidity/mortality rates.

Abstract
BACKGROUND The mechanisms and outcomes in coronavirus disease (COVID-19)-associated stroke are unique from those of non-COVID-19 stroke. OBJECTIVE To describe the efficacy and outcomes of acute revascularization of large vessel occlusion (LVO) in the setting of COVID-19 in an international cohort. METHODS We conducted an international multicenter retrospective study of consecutively admitted patients with COVID-19 with concomitant acute LVO across 50 comprehensive stroke centers. Our control group constituted historical controls of patients presenting with LVO and receiving a mechanical thrombectomy between January 2018 and December 2020. RESULTS The total cohort was 575 patients with acute LVO; 194 patients had COVID-19 while 381 patients did not. Patients in the COVID-19 group were younger (62.5 vs 71.2; P < .001) and lacked vascular risk factors (49, 25.3% vs 54, 14.2%; P = .001). Modified thrombolysis in cerebral infarction 3 revascularization was less common in the COVID-19 group (74, 39.2% vs 252, 67.2%; P < .001). Poor functional outcome at discharge (defined as modified Ranklin Scale 3-6) was more common in the COVID-19 group (150, 79.8% vs 132, 66.7%; P = .004). COVID-19 was independently associated with a lower likelihood of achieving modified thrombolysis in cerebral infarction 3 (odds ratio [OR]: 0.4, 95% CI: 0.2-0.7; P < .001) and unfavorable outcomes (OR: 2.5, 95% CI: 1.4-4.5; P = .002). CONCLUSION COVID-19 was an independent predictor of incomplete revascularization and poor outcomes in patients with stroke due to LVO. Patients with COVID-19 with LVO were younger, had fewer cerebrovascular risk factors, and suffered from higher morbidity/mortality rates.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic is an ongoing public health emergency. While most cases end in asymptomatic or minor illness, there is growing evidence that some COVID-19 infections result in nonconventional dire consequences. We sought to describe the characteristics of patients with intracranial hemorrhage who were infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Also, with the existing literature, we raise the idea of a possible association between SARS-CoV-2 infection and intracranial hemorrhage and propose possible pathophysiological mechanisms connecting the two. Methods We retrospectively collected and analyzed intracranial hemorrhage cases who were also positive for SARS-CoV-2 from 4 tertiary-care cerebrovascular centers. Results We identified a total of 19 patients consisting of 11 males (58%) and 8 females (42%). Mean age was 52.2, with 95% younger than 75 years of age. With respect to COVID-19 illness, 50% had mild-to-moderate disease, 21% had severe disease, and 20% had critical disease requiring intubation. Of the 19 cases, 12 patients had intraparenchymal hemorrhage (63%), 6 had subarachnoid hemorrhage (32%), and 1 patient had a subdural hematoma (5%). A total of 43% had an intracerebral hemorrhage score of 0–2 and 57% a score of 3–6. Modified Rankin Scale cores at discharge were 0–2 in 23% and 3–6 in 77%. The mortality rate was 59%. Conclusions Our series sheds light on a distinct pattern of intracerebral hemorrhage in COVID-19–positive cases compared with typical non–COVID-19 cases, namely the severity of hemorrhage, high mortality rate, and the young age of patients. Further research is warranted to delineate a potential association between SARS-CoV-2 infection and intracranial hemorrhage.

Abstract
BACKGROUND AND PURPOSE Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is associated with hypercoagulability. We sought to evaluate the demographic and clinical characteristics of cerebral venous thrombosis among patients hospitalized for coronavirus disease 2019 (COVID-19) at 6 tertiary care centers in the New York City metropolitan area. MATERIALS AND METHODS We conducted a retrospective multicenter cohort study of 13,500 consecutive patients with COVID-19 who were hospitalized between March 1 and May 30, 2020. RESULTS Of 13,500 patients with COVID-19, twelve had imaging-proved cerebral venous thrombosis with an incidence of 8.8 per 10,000 during 3 months, which is considerably higher than the reported incidence of cerebral venous thrombosis in the general population of 5 per million annually. There was a male preponderance (8 men, 4 women) and an average age of 49 years (95% CI, 36-62 years; range, 17-95 years). Only 1 patient (8%) had a history of thromboembolic disease. Neurologic symptoms secondary to cerebral venous thrombosis occurred within 24 hours of the onset of the respiratory and constitutional symptoms in 58% of cases, and 75% had venous infarction, hemorrhage, or both on brain imaging. Management consisted of anticoagulation, endovascular thrombectomy, and surgical hematoma evacuation. The mortality rate was 25%. CONCLUSIONS Early evidence suggests a higher-than-expected frequency of cerebral venous thrombosis among patients hospitalized for COVID-19. Cerebral venous thrombosis should be included in the differential diagnosis of neurologic syndromes associated with SARS-CoV-2 infection.

Abstract
BACKGROUND The coronavirus disease 2019 is associated with neurological manifestations including stroke. OBJECTIVES We present a case series of coronavirus disease 2019 patients from two institutions with acute cerebrovascular pathologies. In addition, we present a pooled analysis of published data on large vessel occlusion in the setting of coronavirus disease 2019 and a concise summary of the pathophysiology of acute cerebrovascular disease in the setting of coronavirus disease 2019. METHODS A retrospective study across two institutions was conducted between 20 March 2020 and 20 May 2020, for patients developing acute cerebrovascular disease and diagnosed with coronavirus disease 2019. We performed a literature review using the PubMed search engine. RESULTS The total sample size was 22 patients. The mean age was 59.5 years, and 12 patients were female. The cerebrovascular pathologies were 17 cases of acute ischemic stroke, 3 cases of aneurysm rupture, and 2 cases of sinus thrombosis. Of the stroke and sinus thrombosis patients, the mean National Institute of Health Stroke Scale was 13.8 ± 8.0, and 16 (84.2%) patients underwent a mechanical thrombectomy procedure. A favorable thrombolysis in cerebral infarction score was achieved in all patients. Of the 16 patients that underwent a mechanical thrombectomy, the mortality incidence was five (31.3%). Of all patients (22), three (13.6%) patients developed hemorrhagic conversion requiring decompressive surgery. Eleven (50%) patients had a poor functional status (modified Rankin Score 3-6) at discharge, and the total mortality incidence was eight (36.4%). CONCLUSIONS Despite timely intervention and favorable reperfusion, the mortality rate in coronavirus disease 2019 patients with large vessel occlusion was high in our series and in the pooled analysis. Notable features were younger age group, involvement of both the arterial and venous vasculature, multivessel involvement, and complicated procedures due to the clot consistency and burden.

Abstract
OBJECTIVEThromboembolic complications continue to be encountered with Pipeline embolization devices (PEDs) despite routine clopidogrel/aspirin antiplatelet therapy. This study examined the safety and efficacy of prasugrel in the management of clopidogrel-resistant patients treated for cerebral aneurysms.METHODSFour hundred thirty-seven consecutive patients were identified between January 2011 and May 2016. Patients allergic, or having less than 30% platelet inhibition, to a daily 75-mg dose of clopidogrel received 10 mg of prasugrel daily (n = 20) or 90 mg of ticagrelor twice daily (n = 2). The mean (± SD) follow-up duration was 15.8 ± 12.4 months. The primary outcome was the modified Rankin Scale (mRS) score registered before discharge and at each follow-up visit. To control confounding, multivariable mixed-effects logistic regression and propensity score conditioning were used.RESULTSTwenty-six (5.9%) of 437 patients presented with a subarachnoid hemorrhage (SAH). The mean patient age was 56.3 years, and 62 were women (14.2%). One of the 7 patients lost to follow-up received prasugrel. One patient was allergic to clopidogrel and prasugrel simultaneously. All patients receiving prasugrel or ticagrelor (n = 22) had an mRS score ≤ 2 on their latest follow-up visit (mean score 0.67 ± 1.15). In a multivariate analysis, clopidogrel did not affect the mRS score on last follow-up (p = 0.14). Multivariable logistic regression showed that clopidogrel was not associated with an increased long-term recurrence rate (OR 0.17, 95% CI 0.01-2.70, p = 0.21), an increased thromboembolic complication rate (OR 0.46, 95% CI 0.12-1.67, p = 0.24), or an increased hemorrhagic event rate (OR 0.39, 95% CI 0.91-1.64, p = 0.20). None of the patients receiving prasugrel or ticagrelor died or suffered a long-term recurrence or a hemorrhagic event; only 1 patient suffered from mild aphasia subsequent to a thromboembolic event. Three patients taking clopidogrel died during the study: 2 from acute SAH and 1 from intraparenchymal hemorrhage. Clopidogrel was not associated with an increased mortality rate (OR 2.18, 95% CI 0.11-43.27, p = 0.61). The same associations were present in propensity score-adjusted models.CONCLUSIONSIn a cohort of patients treated with PEDs, prasugrel (10 mg/day) was a safe alternative to clopidogrel-resistant or clopidogrel-allergic patients, or nonresponders.

Abstract
BACKGROUND The association between long work hours and outcomes among attending surgeons remains an issue of debate. OBJECTIVE To investigate whether operating emergently the night before an elective case was associated with inferior outcomes among attending neurosurgeons. METHODS We executed a cohort study with unruptured cerebral aneurysm patients, who underwent endovascular coiling or surgical clipping from 2009 to 2013 and were registered in the Statewide Planning and Research Cooperative System database. We investigated the association of treatment by surgeons performing emergency procedures the night before with outcomes of elective cerebral aneurysm treatment using an instrumental variable analysis. RESULTS Overall, 4700 patients underwent treatment for unruptured cerebral aneurysms. There was no difference in inpatient mortality (adjusted difference, -0.7%; 95% confidence interval [CI], -1.4% to 0.02%), discharge to a facility (adjusted difference, -0.1%; 95% CI, -1.2% to 1.2%), or length of stay (adjusted difference, -0.58; 95% CI, -1.66 to 0.50) between patients undergoing elective cerebral aneurysm treatment by surgeons who performed emergency procedures the night before, and those who did not. CONCLUSION Using a comprehensive patient cohort in New York State for elective treatment of unruptured cerebral aneurysms, we did not identify an association of treatment by surgeons performing emergency procedures the night before, with mortality, discharge to a facility, or length of stay. Our study had 80% power to detect differences in mortality (our primary outcome), as small as 4.1%. The results of the present study do not support the argument for regulation of attending work hours.

Abstract
Seizure control is a critical component of care in many neurosurgical conditions. The development of seizures in patients without a previously identified seizure disorder occurs in a significant proportion of traumatic brain injury, subarachnoid hemorrhage, and brain tumor patients. In this literature review and synthesis, we will discuss the incidence of seizures in selected conditions, indications and evidence for the initiation of antiepileptic drugs (AEDs), suggested duration of usage for AEDs, and current AED guidelines by the American Academy of Neurology (AAN), Congress of Neurological Surgeons (CNS), American Academy of Neurological Surgeons (AANS) and international committees.

Abstract
BACKGROUND Multiple external ventricular drain (EVD) simulators have been created, yet their cost, bulky size, and nonreusable components limit their accessibility to residency programs. OBJECTIVE To create and validate an animated EVD simulator that is accessible on a mobile device. METHODS We developed a mobile-based EVD simulator that is compatible with iOS (Apple Inc., Cupertino, California) and Android-based devices (Google, Mountain View, California) and can be downloaded from the Apple App and Google Play Store. Our simulator consists of a learn mode, which teaches users the procedure, and a test mode, which assesses users' procedural knowledge. Twenty-eight participants, who were divided into expert and novice categories, completed the simulator in test mode and answered a postmodule survey. This was graded using a 5-point Likert scale, with 5 representing the highest score. Using the survey results, we assessed the module's face and content validity, whereas construct validity was evaluated by comparing the expert and novice test scores. RESULTS Participants rated individual survey questions pertaining to face and content validity a median score of 4 out of 5. When comparing test scores, generated by the participants completing the test mode, the experts scored higher than the novices (mean, 71.5; 95% confidence interval, 69.2 to 73.8 vs mean, 48; 95% confidence interval, 44.2 to 51.6; P < .001). CONCLUSION We created a mobile-based EVD simulator that is inexpensive, reusable, and accessible. Our results demonstrate that this simulator is face, content, and construct valid.

Abstract
Abstract
BACKGROUND
Pipeline embolization device (PED; Medtronic, Dublin, Ireland) utilization is not limited to the treatment of giant wide-necked aneurysms. It has been expanded to handle small blisters, fusiforms, and dissecting intracranial aneurysms.
OBJECTIVE
To report the use of the PED in various off-label distal cerebral circulation (DCC) arteries with a follow-up to assess clinical outcomes.
METHODS
Between 2011 and 2016, of 437 consecutive patients, 23 patients with aneurysms located in DCCs were treated with PED. Data on patient presentation, aneurysm characteristics, procedural outcomes, postoperative course, and aneurysm occlusion were gathered. To control confounding, we used multivariable logistic regression and propensity score conditioning.
RESULTS
A total of 437 patients (mean age 52.12 years; 62 women [14.2%]) underwent treatment with PED in our institution. Twenty-three of 437 (5.2%) received a pipeline in a distal artery: 11/23 middle cerebral artery, 6/23 posterior cerebral artery, 3/23 anterior cerebral artery (A1/A2, pericallosal artery), and 3/23 posterior inferior cerebellar artery. Twenty percent of the aneurysms were treated in the past, 10% had previously ruptured, and 5.9% ruptured at presentation to our hospital. The mean aneurysm size was 9.0 ± 6 mm. The mean follow-up was 12 mo (SD = 12.5). In multivariable logistic regression, no associations were found between PED deployment in DCCs and aneurysm occlusion or thromboembolic complications. PED use in DCC was associated with a good clinical outcome. Twenty-two people of 23 (95%) had a good clinical outcome in the latest follow-up.
CONCLUSION
Treatment of DCC aneurysms with PED is technically challenging mainly because of the small caliber and tortuosity of the parent arteries. The results of this study further support the safety of flow diverters in the treatment of various distal aneurysms.

Abstract
BACKGROUND Telemedicine rapidly connects patients, with acute ischemic stroke symptoms, with neurovascular specialists for assessment to reduce chemical thrombolysis delivery times. Management of AIS includes maintaining target systolic blood pressures (SBP). In this retrospective study, we assess the efficacy of the telestroke (TS) system at a primary stroke center and the prognostic value of SBP throughout the transportation process. METHODS Patients presenting with acute-onset neurological symptoms to the TS hospitals network, over a 5-year period, were assessed. Those with a confirmed diagnosis of AIS were included. We examined demographics, presenting-NIHSS, last SBP before transfer from the network hospital and continuous BP during transport, stroke risk factors, hospital-course, door-to-needle (DTN) time, treatments, and modified Rankin Scale(mRS). Multivariate analysis was conducted to evaluate the prognostic value of SBP on stroke outcome. RESULTS Of 2,928 patients identified, 1,353 were diagnosed with AIS. Mean age was 66.6 years (SD = 15.4), 47.6% female. Most cases affected the MCA(44.5%). Mean presenting-NIHSS was 8.67(SD = 8.38) and mean SBP was 148 mmHg(SD = 25.39). 73.2% treated using a standard protocol, 23.7% given IVrt-PA, and 6.8% received mechanical thrombectomy(MT). Mean DTN was 96 min(SD = 46; 27.3% <60 min). Age, presenting-NIHSS and pre-existing hypertension were associated with higher mortality and/or higher mRS. SBP was not associated with higher mortality and morbidity. CONCLUSIONS This study displays better clinical outcomes at latest follow-up when compared to current international TS studies. SBP during transportation to the hub hospital did not prove to be a useful prognostic metric. However, future studies should address the limitations of this study to confirm these findings.

Abstract
BACKGROUND We explored regional variation in 30-day ischemic stroke mortality and readmission rates and the extent to which regional differences in patients, hospitals, healthcare resources, and a quality of care composite care measure explain the observed variation. METHODS AND RESULTS This ecological analysis aggregated patient and hospital characteristics from the Get With The Guidelines-Stroke registry (2007-2011), healthcare resource data from the Dartmouth Atlas of Health Care (2006), and Medicare fee-for-service data on 30-day mortality and readmissions (2007-2011) to the hospital referral region (HRR) level. We used linear regression to estimate adjusted HRR-level 30-day outcomes, to identify HRR-level characteristics associated with 30-day outcomes, and to describe which characteristics explained variation in 30-day outcomes. The mean adjusted HRR-level 30-day mortality and readmission rates were 10.3% (SD=1.1%) and 13.1% (SD=1.1%), respectively; a modest, negative correlation (r=-0.17; P=0.003) was found between one another. Demographics explained more variation in readmissions than mortality (25% versus 6%), but after accounting for demographics, comorbidities accounted for more variation in mortality compared with readmission rates (17% versus 7%). The combination of hospital characteristics and healthcare resources explained 11% and 16% of the variance in mortality and readmission rates, beyond patient characteristics. Most of the regional variation in mortality (65%) and readmission (50%) rates remained unexplained. CONCLUSIONS Thirty-day mortality and readmission rates vary substantially across HRRs and exhibit an inverse relationship. While regional variation in 30-day outcomes were explained by patient and hospital factors differently, much of the regional variation in both outcomes remains unexplained.

Abstract
BACKGROUND An increasing number of elderly patients with dementia are undergoing surgical operations. Little is known about the differential impact of dementia on surgical outcomes. We investigated whether demented patients undergoing surgical operations have worse outcomes than their non-demented counterparts. METHODS We performed a cohort study of all patients undergoing a series of surgical operations who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2009 to 2013. We examined the association of dementia with inpatient case-fatality, discharge to a facility, and length of stay (LOS). Coarsened exact matching was used to balance comorbidities among the comparison groups, and mixed effect methods were used to control for clustering at the hospital level. RESULTS During the study period, 342,075 patients underwent surgical operations that met the inclusion criteria. Multivariable logistic regression models, after coarsened exact matching, demonstrated that demented patients were not associated with higher case-fatality (OR, 0.43; 95% CI, 0.13-1.36), but were associated with higher rates of discharge to a facility (OR, 1.71; 95% CI, 1.26-2.31) and longer LOS (Adjusted difference, 31%; 95% CI, 26%-36%). These persisted in pre-specified subgroups stratified on particular operations. CONCLUSIONS Using a comprehensive all-payer cohort of surgical patients in New York State we identified an association of dementia with increased rate of discharge to rehabilitation and longer LOS. No difference was identified in the case fatality of the two groups. Policy makers, payers, and physicians should take these findings into account when designing new policies, and when counseling patients.

Abstract
BACKGROUND The association of Magnet hospital status with improved surgical outcomes remains an issue of debate. OBJECTIVE To investigate whether hospitalization in a Magnet hospital is associated with improved outcomes for patients undergoing neurosurgical operations. METHODS A cohort study was executed using all patients undergoing neurosurgical operations in New York registered in the Statewide Planning and Research Cooperative System database from 2009 to 2013. We examined the association of Magnet status hospitalization after neurosurgical operations with inpatient case fatality and length of stay (LOS). We employed an instrumental variable analysis to simulate a randomized trial. RESULTS Overall, 190 787 patients underwent neurosurgical operations. Of these, 68 046 (35.7%) were hospitalized in Magnet hospitals, and 122 741 (64.3%) in non-Magnet institutions. Instrumental variable analysis demonstrated that hospitalization in Magnet hospitals was associated with decreased case fatality (adjusted difference, -0.8%; -95% confidence interval, -0.7% to -0.6%), and LOS (adjusted difference, -1.9; 95% confidence interval, -2.2 to -1.5) in comparison to non-Magnet hospitals. These associations were also observed in propensity score adjusted mixed effects models. These associations persisted in prespecified subgroups of patients undergoing spine surgery, craniotomy for tumor resection, or neurovascular interventions. CONCLUSION We identified an association of Magnet hospitals with lower case fatality, and shorter LOS in a comprehensive New York State patient cohort undergoing neurosurgical procedures.

Abstract
OBJECTIVES Neurologists have continually led the assessment and management of Acute Ischemic Stroke(AIS) by use of IV-rtPA, anti-platelet therapy, antihypertensives, and other pharmacologic agents. Since the advent of mechanical thrombectomy(MT) and its proven efficacy, neurovascular surgeons(NS) are playing an increasingly important role in the management and overall care of AIS. We assessed outcomes of AIS patients managed by NS, who have been traditionally managed by neurologists. PATIENTS AND METHODS Outcomes of AIS patients who presented to the telestroke system, over a 5-year period, were assessed. NIHSS and mRS stroke scales were used as outcome metrics. Multivariate analysis was conducted to compare outcomes of patients treated by neurovascular surgeons and those treated by neurologists. RESULTS 1353 AIS patients were identified. 21.6% received care from neurosurgeons and 78.4% received care from neurologists. Of the neurologist-managed group: 7.8% received MT and were followed by NS, 34% received IVrt-PA, average discharge NIHSS = 9.0 (SD = 8.42), latest follow-up mRS < 2 = 57.5% and mortality rate = 9.4%. Of the neurovascular surgeon-managed group: 7.4% patients received MT, 20% received IVrt-PA, average discharge NIHSS = 0.14(SD = 0.72), latest follow-up mRS ≤2 = 98.6% and mortality rate = 8.3%. There were no significant differences between groups in MT use (OR 1.22; CI95%, 0.971-2.09; p = 0.464), IVrt-PA administration (OR 0.98; CI95%, 0.70-1.38; p = 0.924), mortality rate (OR 1.21; 0.71-2.03; p = 0.483) and patients' latest mRS, p = 0.873. CONCLUSIONS AIS requires multidisciplinary management. Care provided by neurosurgeons has similar efficacy and patient outcomes as the care provided by neurologists. These findings support the role and ability of neurosurgeons to manage and care for these patients.

Abstract
Direct oral anticoagulant (DOAC) use is growing as monotherapy and combined with platelet inhibitors. The safety of such combination therapy, especially in comparison to regimens including warfarin, in real world populations remains uncertain. We investigated hemorrhage associated with DOAC and antiplatelet combination therapy in a cohort of elderly coronary artery stent recipients. We employed Medicare data 2010-2013 for a 40% random sample of beneficiaries enrolled in inpatient, outpatient and prescription benefits. We used Cox proportional hazards models to examine the association of the combination anticoagulant (DOAC or warfarin) plus antiplatelets with major hemorrhage events (upper gastrointestinal or intracranial) in the 12 months following stent placement. We identified 70,900 stent recipients. 14.4% had atrial fibrillation (AF) diagnosis preoperatively. Among the 24.5 million observation days, exposure distribution was: 73.8% antiplatelets only, 4.7% antiplatelets plus warfarin, 0.6% antiplatelets plus DOAC, 2.2% warfarin only, 0.3% DOAC only and 18.4% no observed antiplatelets or anticoagulant. Overall, 8,029 patients (11.3%) experienced major hemorrhage. Among AF patients, compared to antiplatelets only, DOAC plus antiplatelets was associated with increased hemorrhage risk (HR, 1.94; 95%CI, 1.48-2.54); warfarin plus antiplatelets conferred comparable bleed risk (HR, 1.69; 95%CI, 1.47-1.94). In the non-AF group, compared to antiplatelets alone, combination DOAC plus antiplatelets (HR, 3.09; 95%CI, 2.15-4.46), and warfarin plus antiplatelets (HR, 2.21; 95%CI, 1.97-2.48) conferred greater bleed risk. Among elderly coronary artery stent recipients with AF, the two drug combinations, DOAC plus antiplatelets and warfarin plus antiplatelets, were associated with similarly increased risk of major hemorrhage compared to antiplatelets alone.

Abstract
PURPOSE The quality of physicians practicing in hospitals recognized for nursing excellence by the American Nurses Credentialing Center has not been studied before. We investigated whether Magnet hospital recognition is associated with higher quality of physicians performing neurosurgical procedures. MATERIALS AND METHODS We performed a cohort study of patients undergoing neurosurgical procedures from 2009-2013, who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database. Propensity score adjusted multivariable regression models were used to adjust for known confounders, with mixed effects methods to control for clustering at the facility level. An instrumental variable analysis was used to control for unmeasured confounding and simulate the effect of a randomized trial. RESULTS During the study period, 185,277 patients underwent neurosurgical procedures, and met the inclusion criteria. Of these, 66,607 (35.6%) were hospitalized in Magnet hospitals, and 118,670 (64.4%) in non-Magnet institutions. Instrumental variable analysis demonstrated that undergoing neurosurgical operations in Magnet hospitals was associated with a 13.6% higher chance of being treated by a physician with superior performance in terms of mortality (95% CI, 13.2% to 14.1%), and a 4.3% higher chance of being treated by a physician with superior performance in terms of length-of-stay (LOS) (95% CI, 3.8% to 4.7%) in comparison to non-Magnet institutions. The same associations were present in propensity score adjusted mixed effects models. CONCLUSIONS Using a comprehensive all-payer cohort of neurosurgical patients in New York State we identified an association of Magnet hospital recognition with superior physician performance.

Abstract
Background:
The use of flow diverters has stretched to address several sets of aneurysms such as giant, small blister, fusiform, distal IAs of the anterior and posterior circulation. Only very few studies considered addressing the rate and the characteristics of intra-pipeline stenosis(IPS).
Objective:
we aimed to appraise the prevalence, the predictors and outcomes of IPS and the consequent clinical implications.
Method:
We reviewed the charts of 537patients treated with pipeline for their IAs between 2011 and 2017. We consecutively gathered clinical and angiographic data related to IPS. Stenosis was interpreted by the operating neurointerventionist: mild<50%, moderate50-75% and severe>75%. To control confounding, we used multivariable logistic regression and propensity score conditioning.
Results:
Of 537patients, 31(15.6% were females) had an angiography perceived IPS. 8(25.8%) of our patients were >65yo. 23(74%) patients had their IPS detected at 6moths follow-up. The mean follow-up time to detect IPS was 7.2months(SD=6.33). 23(74.2%) and 8(25.8%) patients had their aneurysms located in the anterior & posterior circulation respectively. The average pipeline size was 3.8x19.4mm. Six patients had an IPS located, at the proximal (n=3) and distal end (n=3) of the pipeline, 25 patients had IPS somewhere along the body of the pipeline. 20/31 patients had mild IPS, 5/31 had moderate IPS and 6/31 had severe IPS. Regression of IPS was perceived in 9/31 patient. IPS progression was noted in one patient from 70% to 90%. 4(12%) patients had >90% IPS, all were symptomatic: 3 had a right hemispheric stroke and 1 patient precipitated an intra-cerebral hemorrhage. In multivariable analysis, patients of older age (>65yo) were less likely to develop IPS (OR0.96;CI95%,0.9-1;p=0.03). Those with a history of hypertension were more prone to develop IPS (OR3.3;CI95%,1.1-9.8;p=0.03). Per-procedural use of balloon angioplasty, aneurysm size and ruptured aneurysm were not independent predictors of IPS.
Conclusion:
Young patients <65yo and patients with hypertension are more prone to develop IPS. Balloon angioplasty does not predict IPS. IPS remains a benign development, most likely to regress than to progress into a clinically manifest stenosis.

Abstract
Background Public reporting is at the forefront of health care reform. Objective To investigate whether patient satisfaction as expressed in a public reporting platform correlates with objective outcomes for cranial neurosurgery patients. Methods We performed a cohort study involving patients undergoing cranial neurosurgery from 2009 to 2013 who were registered in the Statewide Planning and Research Cooperative System database. This cohort was merged with the corresponding data from the Centers for Medicare and Medicaid Services Hospital Compare website. The association of patient satisfaction metrics with outcomes was examined with the use of a propensity-adjusted regression model. Results Overall, 19 591 patients underwent cranial neurosurgery during the study. Using a propensity-adjusted multivariable regression analysis, we demonstrated that hospitals with a greater percentage of patient-assigned "high" scores had decreased mortality (OR, 0.60; 95% CI, 0.53-0.67), rate of discharge to rehabilitation (OR, 0.93; 95% CI, 0.88-0.98), length of stay (adjusted difference, -1.29; 95% CI, -1.46 to -1.13), and hospitalization charges (adjusted difference, -23%; 95% CI, -36% to -9%) after cranial neurosurgery. Similar associations were identified for hospitals with a higher percentage of patients, who would recommend these institutions to others. Conclusion In a Centers for Medicare and Medicaid Services Hospital Compare-Statewide Planning and Research Cooperative System merged dataset, we observed an association of higher performance in patient satisfaction measures with decreased mortality, rate of discharge to rehabilitation, hospitalization charges, and length of stay.

Abstract
OBJECTIVEFragmentation of care has been recognized as a major contributor to 30-day readmissions after surgical procedures. The authors investigated the association of evaluation in the hospital where the original procedure was performed with the rate of 30-day readmissions for patients presenting to the emergency department (ED) after craniotomy for primary brain tumor resection.METHODSA cohort study was conducted, involving patients who were evaluated in the ED within 30 days after discharge following a craniotomy for primary brain tumor resection between 2009 and 2013, and who were registered in the Statewide Planning and Research Cooperative System (SPARCS) database of New York State. A propensity score–adjusted model was used to control for confounding, whereas a mixed-effects model accounted for clustering at the hospital level.RESULTSOf the 610 patients presenting to the ED, 422 (69.2%) were evaluated in a hospital different from the one where the original procedure was performed (28.9% were readmitted), and 188 (30.8%) were evaluated at the original hospital (20.3% were readmitted). In a multivariable analysis, the authors demonstrated that being evaluated in the ED of the original hospital was associated with a decreased rate of 30-day readmission (OR 0.64, 95% CI 0.41–0.98). Similar associations were found in a mixed-effects logistic regression model (OR 0.63, 95% CI 0.40–0.96) and a propensity score–adjusted model (OR 0.64, 95% CI 0.41–0.98). This corresponds to one less readmission per 12 patients evaluated in the hospital where the original procedure was performed.CONCLUSIONSUsing a comprehensive all-payer cohort of patients in New York State who were evaluated in the ED after craniotomy for primary brain tumor resection, the authors identified an association of assessment in the hospital where the original procedure was performed with a lower rate of 30-day readmissions. This underscores the potential importance of continuity of care in readmission prevention for these patients.

Abstract
BACKGROUND The interpretation of the results of prior studies on the association of hospital teaching status with surgical outcomes is limited by selection bias. We investigated whether undergoing surgical operations in teaching hospitals is associated with improved outcomes. METHODS We performed a cohort study of all patients undergoing spine and cranial operations who were registered in the New York Statewide Planning and Research Cooperative System database from 2009 to 2013. We examined the association of teaching status (defined as academic affiliation for the primary analysis) with inpatient case fatality, discharge to a facility, and length of stay (LOS). An instrumental variable analysis was used to control for unmeasured confounding and to simulate the effect of a randomized trial. RESULTS During the study period, 186,483 patients underwent surgical operations that met the inclusion criteria. Instrumental variable analysis demonstrated that hospitalization in teaching hospitals was associated with higher rates of case fatality (adjusted difference, 25%; 95% confidence interval [CI], 4%-46%), discharge to a facility (adjusted difference, 5.7%; 95% CI, 4.5%-7.0%), and longer LOS (adjusted difference, 31.4%; 95% CI, 16.0%-46.1%) in comparison with nonteaching hospitals. The same associations were present in propensity score adjusted mixed effects models. These persisted in prespecified subgroups stratified on particular operations and for different definitions of teaching hospitals. CONCLUSIONS Using a comprehensive all-payer cohort of surgical patients in New York State, we identified an association of treatment in teaching hospitals with increased case fatality, rate of discharge to rehabilitation, and longer LOS. Further research into the factors contributing to superior outcomes in nonteaching institutions is warranted.

Abstract
Objective To determine physician characteristics associated with exnovation (scaling back on use) and de-adoption (abandoning use) of carotid revascularization.Design Retrospective longitudinal cohort study.Setting Medicare claims linked to the Doximity database provider registry, 2006-13.Participants 9158 physicians who performed carotid revascularization on Medicare patients between 2006 and 2013.Main outcome measures The primary outcomes were the number of carotid revascularization procedures for each physician per year at the end of the sample period, and the percentage change in the volume of carotid revascularization procedures.Results At baseline (2006-07), 9158 physicians performed carotid revascularization. By 2012-13 the use of revascularization in this cohort had declined by 37.7%, with two thirds attributable to scaling back (exnovation) rather than dropping the procedure entirely (de-adoption). Compared with physicians with fewer than 12 years of experience, those with more than 25 years of experience decreased use by an additional 23.0% (95% confidence interval -36.7% to -9.2%). The lowest rates of decline occurred in physicians specializing in vascular or thoracic surgery, for whom the procedures accounted for a large share of revenue. Physicians with high proportions of patients aged more than 80 years or with asymptomatic carotid stenosis were less likely to reduce their use of carotid revascularization.Conclusion Surgeons with more experience and the lowest share in carotid revascularization practice reduced their use of the procedure the most. These practice factors should be considered in quality improvement efforts when the evidence base evolves away from a specific treatment.

Abstract
Flow diversion with the Pipeline Embolization Device (PED) is reported as a safe and efficient treatment for patients with intracranial aneurysms; however, literature discussing the antiplatelet (APT) regimen used before and after the PED is limited. Our aim was to systematically review and summarize available data regarding the APT regimen and the platelet function test (PFT) that was used. We also sought to provide an overview of the aneurysm morphologies and adverse event rates associated with the PED use. This systematic review was conducted according to the PRISMA statement and eligible studies were identified through search of the PubMed and Cochrane databases. We reviewed 28 studies, involving 1556 patients that underwent aneurysm treatment with the PED. The preprocedural aspirin (ASA) 300- 325mg (2-14days) combined with clopidogrel 75mg (3 to >10days) were used as a treatment strategy in 61.7% of patients and ASA 81mg with clopidogrel 75mg for 5-10days for 27%. Patients who received low versus high dose pre-PED ASA, were at less risk for a hemorrhagic event (0.7% versus 3.3%, p=0.053); however no statistical significance was reached. There was also lack of relationship between patients that received low versus high preprocedural ASA in terms of thromboembolic events. Regarding postprocedural APT, ASA (>6months) and clopidogrel (3- 12 months) was the regimen of choice for 93% of patients. Most studies conducted at least one PFT, most common being the VerifyNow. The most frequently reported target P2Y12 Reaction unit (PRU) and Aspirin Reaction Unit (ARU) values were <230 and <550 respectively. There was no statistically demonstrable difference in regards to thrombotic events between centers that conducted at least one PFT and centers that did not test their patients with a PFT. The overall rates of symptomatic thrombotic episodes were 6.6% and hemorrhagic were 3%. The pre- and post-PED APT dose and duration varies across different institutions. More prospective studies are needed to compare the efficacy of different APT agents and reach conclusions regarding use of PFT and platelet reaction values in order to decrease hemorrhagic and thromboembolic complications associated with the PED.

Abstract
BACKGROUND Centers of excellence focusing on quality improvement have demonstrated superior outcomes for a variety of surgical interventions. We investigated the presence of access disparities to hospitals recognized by the Magnet Recognition Program of the American Nurses Credentialing Center (ANCC) for patients undergoing neurosurgical operations. METHODS We performed a cohort study of all neurosurgery patients who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2009 to 2013. We examined the association of African-American race and lack of insurance with Magnet status hospitalization for neurosurgical procedures. A mixed effects propensity adjusted multivariable regression analysis was used to control for confounding. RESULTS During the study period, 190,535 neurosurgical patients met the inclusion criteria. Using a multivariable logistic regression, we demonstrate that African-Americans had lower admission rates to Magnet institutions (OR 0.62; 95% CI, 0.58-0.67). This persisted in a mixed effects logistic regression model (OR 0.77; 95% CI, 0.70-0.83) to adjust for clustering at the patient county level, and a propensity score adjusted logistic regression model (OR 0.75; 95% CI, 0.69-0.82). Additionally, lack of insurance was associated with lower admission rates to Magnet institutions (OR 0.71; 95% CI, 0.68-0.73), in a multivariable logistic regression model. This persisted in a mixed effects logistic regression model (OR 0.72; 95% CI, 0.69-0.74), and a propensity score adjusted logistic regression model (OR 0.72; 95% CI, 0.69-0.75). CONCLUSIONS Using a comprehensive all-payer cohort of neurosurgery patients in New York State we identified an association of African-American race and lack of insurance with lower rates of admission to Magnet hospitals.

Abstract
Access disparities to centers of excellence can have detrimental consequences for population health. We investigated the presence of racial disparities in the access of stroke patients to hospitals recognized by the Magnet Recognition Program of the American Nurses Credentialing Center (ANCC). We performed a cohort study of all ischemic stroke patients who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2009 to 2013. We examined the association of African-American race with Magnet status hospitalization after ischemic stroke. A mixed effects propensity adjusted multivariable regression analysis was used to control for confounding. During the study period, 176,557 patients presented with ischemic stroke, and met the inclusion criteria. Overall, 4,624 (13.7%) African-Americans, and 27,468 (19.2%) non African-Americans with ischemic stroke were admitted to Magnet hospitals. Using a multivariable logistic regression, we demonstrate that African-Americans were associated with lower admission rates to Magnet institutions (OR 0.70; 95% CI, 0.68-0.73) (Table 2). This persisted in a mixed effects logistic regression model (OR 0.75; 95% CI, 0.71-0.78) to adjust for clustering at the county level, and a propensity score adjusted logistic regression model (OR 0.87; 95% CI, 0.83-0.90). Using a comprehensive all-payer cohort of ischemic stroke patients in New York State we identified an association of African-American race with lower rates of admission to Magnet hospitals.

Abstract
BACKGROUND It is unclear whether publicly reported benchmarks correlate with quality of physicians and institutions. We investigated the association of patient satisfaction measures from a public reporting platform with performance of neurosurgeons in New York State. METHODS This cohort study comprised patients undergoing neurosurgical operations from 2009 to 2013 who were registered in the Statewide Planning and Research Cooperative System database. The cohort was merged with publicly available data from the Centers for Medicare and Medicaid Services Hospital Compare website. Propensity-adjusted regression analysis was used to investigate the association of patient satisfaction metrics with neurosurgeon quality, as measured by the neurosurgeon's individual rate of mortality and average length of stay. RESULTS During the study period, 166,365 patients underwent neurosurgical procedures. Using propensity-adjusted multivariable regression analysis, we demonstrated that undergoing neurosurgical operations in hospitals with a greater percentage of patient-assigned "high" scores was associated with higher chance of being treated by a physician with superior performance in terms of mortality (odds ratio 1.90, 95% confidence interval 1.86-1.95), and a higher chance of being treated by a physician with superior performance in terms of length of stay (odds ratio 1.24, 95% confidence interval 1.21-1.27). Similar associations were identified for hospitals with a higher percentage of patients who claimed they would recommend these institutions to others. CONCLUSIONS Merging a comprehensive all-payer cohort of neurosurgery patients in New York State with data from the Hospital Compare website, we observed an association of superior hospital-level patient satisfaction measures with objective performance of individual neurosurgeons in the corresponding hospitals.

Abstract
BACKGROUND It is not clear whether Magnet recognition by the American Nurses Credentialing Center (nursing excellence program) is associated with improved patient outcomes. We investigated whether hospitalization in a Magnet hospital is associated with improved outcomes for patients with ischemic stroke. METHODS AND RESULTS We performed a cohort study of patients with ischemic stroke from 2009 to 2013, who were registered in the New York Statewide Planning and Research Cooperative System database. Propensity-score-adjusted multivariable regression models were used to adjust for known confounders, with mixed effects methods to control for clustering at the facility level. An instrumental variable analysis was used to control for unmeasured confounding and simulate the effect of a randomized trial. During the study period, 176 557 patients were admitted for ischemic stroke, and met the inclusion criteria. Of these, 32 092 (18.2%) were hospitalized in Magnet hospitals, and 144 465 (81.8%) in non-Magnet institutions. Instrumental variable analysis demonstrated that hospitalization in Magnet hospitals was associated with lower case-fatality (adjusted difference, -23.9%; 95% CI, -29.0% to -18.7%), length of stay (adjusted difference, -0.4; 95% CI, -0.8 to -0.1), and rate of discharge to a facility (adjusted difference, -16.5%; 95% CI, -20.0% to -13.0%) in comparison to non-Magnet hospitals. The same associations were present in propensity-score-adjusted mixed effects models. CONCLUSIONS Using a comprehensive all-payer cohort of patients with ischemic stroke in New York State, we identified an association of treatment in Magnet hospitals with lower case-fatality, discharge to a facility, and length of stay. Further research into the factors contributing to the superiority of Magnet hospitals in stroke care is warranted.

Abstract
OBJECTIVE The accuracy of public reporting in health care, especially from private vendors, remains an issue of debate. The authors investigated the association of the publicly reported physician complication rates in an online platform with real-world adverse outcomes of the same physicians for patients undergoing posterior lumbar fusion. METHODS The authors performed a cohort study involving physicians performing posterior lumbar fusions between 2009 and 2013 who were registered in the Statewide Planning and Research Cooperative System database. This cohort was merged with publicly available data over the same time period from ProPublica, a private company. Mixed-effects multivariable regression models were used to investigate the association of publicly available complication rates with the rate of discharge to a rehabilitation facility, length of stay, mortality, and hospitalization charges for the same surgeons. RESULTS During the selected study period, there were 8,457 patients in New York State who underwent posterior lumbar fusion performed by the 56 surgeons represented in the ProPublica Surgeon Scorecard over the same time period. Using a mixed-effects multivariable regression model, the authors demonstrated that publicly reported physician-level complication rates were not associated with the rate of discharge to a rehabilitation facility (OR 0.97, 95% CI 0.72-1.31), length of stay (adjusted difference -0.1, 95% CI -0.5 to 0.2), mortality (OR 0.87, 95% CI 0.49-1.55), and hospitalization charges (adjusted difference $18,735, 95% CI -$59,177 to $96,647). Similarly, no association was observed when utilizing propensity score-adjusted models, and when restricting the cohort to a predefined subgroup of Medicare patients. CONCLUSIONS After merging a comprehensive all-payer posterior lumbar fusion cohort in New York State with data from the ProPublica Surgeon Scorecard over the same time period, the authors observed no association of publicly available physician complication rates with objective outcomes.

Abstract
Background:
Promoting intravenous tissue plasminogen activator (IV tPA) in treating eligible patients with acute ischemic stroke (AIS) is critical in reducing overall stroke burden. Effective telestroke networks are proven to facilitate higher rates of IV tPA use. Increasing data on stroke outcomes continues to emerge with expansion of telestroke services nationwide.
Objective:
To estimate the incidence of intracranial hemorrhage (ICH) in AIS patients treated with IV tPA via telestroke evaluation.
Methods:
In this study, data from a large telestroke network comprising 36 hospitals from 3 States and associated with a university-based health system and comprehensive stroke center was utilized. Data included total of 3198 acute telestroke evaluations performed within the network between January 2014 and June 2016. Distance of spoke hospitals from the hub ranged between 2.5 and 125 miles. All telestroke consultations were done using the remote presence robotic technology. 15% of all telestroke evaluations and 51% of post-IV tPA patients were transferred to the hub. CT imaging was used for identification and ICH as defined mainly in the NINDS trial was used for comparison.
Results:
Mean age of patients was 67 years (sd=16) and majority were women (n=1759, 55%). Average NIHSS score at presentation was 7. IV tPA was administered to 18% of all telestroke patients. Post IV tPA, any ICH (symptomatic or not) was noted in 8.7% of patients. Petechial hemorrhage was most frequently reported finding. Rate of any ICH in our telestroke population was relatively lower compared to the ECASS II (39%, p<0.001), ECASS III (27%, p<0.001), SITS-MOST (9.6%, p=0.63), ATLANTIS (11.4%, p=0.30), and higher than the NINDS (6.4%, p=0.29).
Conclusions:
Higher rate of IV tPA use and lower rate of hemorrhagic complication observed in this large study further supports and strengthens the role of telestroke technology and expertise in treatment of AIS.

Abstract
Background:
The impact of anesthesia technique on the outcomes of mechanical thrombectomy for acute ischemic stroke remains an issue of debate, and has not been studied in clinical trials. We investigated the association of general anesthesia with outcomes in patients undergoing mechanical thrombectomy for ischemic stroke.
Methods:
We performed a cohort study involving patients undergoing mechanical thrombectomy for ischemic stroke from 2009-2013, who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database. An instrumental variable (hospital rate of general anesthesia) analysis was used to simulate the effects of randomization and investigate the association of anesthesia technique with case-fatality and length of stay (LOS).
Results:
Of the 1,308 patients undergoing mechanical thrombectomy for acute ischemic stroke, 492 (37.6%) underwent general anesthesia, and 816 (62.4%) underwent conscious sedation. Employing an instrumental variable analysis, we identified that general anesthesia was associated with a 6.4% increased case-fatality (95% CI, 1.9% to 11.0%), and 8.4 days longer LOS (95% CI, 2.9 to 14.0) in comparison to conscious sedation. This corresponded to 15 patients needing to be treated with conscious sedation to prevent one death. Our results were robust in a sensitivity analysis utilizing mixed effects regression, and propensity score adjusted regression models.
Conclusions:
Using a comprehensive all-payer cohort of acute ischemic stroke patients undergoing mechanical thrombectomy in New York State, we identified an association of general anesthesia with increased case fatality and LOS. These considerations should be taken into account when standardizing acute stroke care.

Abstract
BACKGROUND Despite the increasing number of elderly patients undergoing neurosurgical interventions, there are limited resources for preoperative assessment of frailty in this population. We investigated the association between recent history of falls and surgical outcomes for these patients. METHODS We performed a prospective cohort study of all patients, 65 years and older, undergoing elective neurosurgical procedures from 2014-2015 in a tertiary referral medical center. We examined the association of sustaining a fall in the 6 months before the operation with discharge to a facility, readmissions, and complications in the first 30 days after discharge. In order to control for confounding, we used multivariable regression models and propensity score conditioning. Mixed-effects models were used to control for clustering at the surgeon level. RESULTS During the study period, 143 elderly patients underwent a neurosurgical procedure and met the inclusion criteria. Of these, 53.1% had a history of falls preoperatively. Mixed-effects multivariable logistic regression analysis demonstrated an association between preoperative falls and discharge to a facility (odds ratio [OR], 1.35; 95% confidence interval [CI], 1.23-1.47), 30-day readmissions (OR, 1.57; 95% CI, 1.36-1.78), and 30-day complications (OR, 1.13; 95% CI, 1.03-1.23). Similar associations were present in propensity score-adjusted models and models stratified by cranial and spinal procedures. CONCLUSIONS History of at least 1 fall in the 6 months before a neurosurgical operation was associated with increased risk of discharge to a facility, readmissions, and complications in the first 30 days after discharge. History of prior falls should be taken into account during the preoperative risk assessment of neurosurgical patients.

Abstract
BACKGROUND CONTEXT The value of continuity of care in preventing 30-day readmissions after surgical procedures remains an issue of debate. PURPOSE This study aimed to investigate the association of being evaluated in the emergency room (ER) of the hospital where the original procedure was performed with 30-day readmissions for spine surgery patients. STUDY DESIGN/SETTING This is a cohort study. PATIENT SAMPLE A total of 16,483 spine surgery patients were evaluated in the emergency department within 30-days postoperatively. OUTCOME MEASURES A 30-day post-discharge readmission was the outcome measure. METHODS We performed a cohort study involving patients who were evaluated in the ER within 30-days after discharge following spine surgery from 2009 to 2013, and were registered in the Statewide Planning and Research Cooperative System database. A propensity score adjusted model was used to control for confounding. RESULTS From our patients, 11,638 (70.6%) were seen in a hospital different from the one where the original procedure was performed (12.0% readmitted), and 4,845 (29.4%) were evaluated at the original hospital (10.9% readmitted). In a multivariable analysis, we demonstrated that being evaluated in the original hospital was associated with decreased rate of 30-day readmission (odds ratio [OR], 0.87; 95% confidence interval [CI], 0.77-0.97). We found similar associations in a propensity score adjusted model (OR, 0.87; 95% CI, 0.78-0.97). This corresponded to seven patients who needed to be evaluated in the hospital where the original procedure was performed to prevent one readmission. CONCLUSIONS Using a comprehensive all-payer cohort of patients in New York State, who were evaluated in the ER after spine surgery, we identified an association of assessment in the hospital where the original procedure was performed with lower rate of 30-day readmissions. This underscores the potential importance of continuity of care in readmission prevention for these patients.

Abstract
OBJECTIVE The impact of procedural volume on the outcomes of cerebrovascular surgery in children has not been determined. In this study, the authors investigated the association of operative volume on the outcomes of cerebrovascular neurosurgery in pediatric patients. METHODS The authors performed a cohort study of all pediatric patients who underwent a cerebrovascular procedure between 2003 and 2012 and were registered in the Kids' Inpatient Database (KID). To control for confounding, the authors used multivariable regression models, propensity-score conditioning, and mixed-effects analysis to account for clustering at the hospital level. RESULTS During the study period, 1875 pediatric patients in the KID underwent cerebrovascular neurosurgery and met the inclusion criteria for the study; 204 patients (10.9%) underwent aneurysm clipping, 446 (23.8%) underwent coil insertion for an aneurysm, 827 (44.1%) underwent craniotomy for arteriovenous malformation resection, and 398 (21.2%) underwent bypass surgery for moyamoya disease. Mixed-effects multivariable regression analysis revealed that higher procedural volume was associated with fewer inpatient deaths (OR 0.58; 95% CI 0.40-0.85), a lower rate of discharges to a facility (OR 0.87; 95% CI 0.82-0.92), and shorter length of stay (adjusted difference -0.22; 95% CI -0.32 to -0.12). The results in propensity-adjusted multivariable models were robust. CONCLUSIONS In a national all-payer cohort of pediatric patients who underwent a cerebrovascular procedure, the authors found that higher procedural volume was associated with fewer deaths, a lower rate of discharges to a facility, and decreased lengths of stay. Regionalization initiatives should include directing children with such rare pathologies to a center of excellence.
