Nationwide analysis of hospital-to-hospital transfer in patients with aneurysmal subarachnoid hemorrhage requiring aneurysm repair.

Nationwide analysis of hospital-to-hospital transfer in patients with aneurysmal subarachnoid hemorrhage requiring aneurysm repair. J Neurosurg. 2018 Oct 01;:1-8 Authors: Abstract OBJECTIVEAneurysmal subarachnoid hemorrhage (aSAH) has devastating consequences. The association between higher institutional volumes and improved outcomes for aSAH patients has been studied extensively. However, the literature exploring patterns of transfer in this context is sparse. Expansion of the endovascular workforce has raised concerns about the decentralization of care, reduced institutional volumes, and worsened patient outcomes. In this paper, the authors explored various patient and hospital factors associated with the transfer of aSAH patients by using a nationally representative database.METHODSThe 2013 and 2014 years of the National Inpatient Sample (NIS) were used to define an observational cohort of patients with ruptured brain aneurysms. The initial search identified patients with SAH (ICD-9-CM 430). Those with concomitant codes suggesting trauma or other intracranial vascular abnormalities were excluded. Finally, the patients who had not undergone a subsequent procedure to repair an intracranial aneurysm were excluded. These criteria yielded a cohort of 4373 patients, 1379 of whom had undergone microsurgical clip ligation and 2994 of whom had undergone endovascular repair. The outcome of interest was transfer status, and the NIS data element TRAN_IN was used...

CONCLUSION Individuals with HAP during acute hospitalization have worse long-term prognosis and greater hospital resource utilization. Preventing HAP may be cost-effective and improve long-term recovery for individuals with TBI. Future studies should compare the effectiveness of different prophylaxis methods to prevent HAP. LEVEL OF EVIDENCE Prospective cohort study, level III.

AbstractThe present study was undertaken to explore the role of total flavones of Camellia (TFC) on cerebral injury following subarachnoid hemorrhage (SAH) in rats. We showed that the increase of malondialdehyde (MDA) level in brain tissues, leakages of neuron-specifc enolase (NSE) and lactate dehydrogenase (LDH) from brain tissues to serum at 48 h after SAH were significantly blocked by TFC treatment. Besides, TFC treatment could reduce brain edema and the Bax/Bcl-2 ratio in hippocampal tissues at mRNA and protein levels at 48 h after SAH. In addition, and the reduction of neurological scores at 7d after SAH were signific...

Objective: Japan has the largest elderly population in the world. As data on the clinical outcomes in elderly patients with aneurysmal subarachnoid hemorrhage (aSAH), including those older than 80 years, are lacking, we analyzed the characteristics of 54,805 aSAH patients and recorded their treatments and clinical outcomes using a Japanese nationwide inpatient database. Methods: Using the Japanese Diagnostic Procedure Combination database, we identified aSAH patients aged 18 years or older who were hospitalized between July 1, 2010 and March 31, 2016.

In this study, we aim to validate and compare the aneurysmal SAH grading scales in angiogram-negative SAH patients. There were 190 angiogram-negative SAH patients analyzed from January 2014 to December 2015. The outcomes were measured by delayed cerebral ischemia (DCI) and poor outcome (defined as modified Rankin Scale (mRS) 3-6 or 4-6). The predictive performance of the grading scales was assessed via evaluation of distribution, trend, association, and discrimination. In regard to the distribution, none of the patients were categorized as HAIR 8 and SAH score 8. Both grading scales indicated a significant trend between sc...

Abstract OBJECTIVE: The Subarachnoid Hemorrhage Early Brain Edema Score (SEBES) system measures cerebral edema on CT and can be used to predict outcome after subarachnoid hemorrhage (SAH). The authors developed a modified SEBES (SEBES 6c) and assessed whether it could predict outcome after SAH better than the SEBES. Furthermore, they verified the age dependency of these scores. METHODS: In this retrospective study, all patients with aneurysmal SAH in the period from January 2011 to February 2017 at a single institution were analyzed. The SEBES, which is based on the absence of visible sulci at two defined CT ...

Background: Hyponatremia is a common complication after aneurysmal subarachnoid hemorrhage (aSAH). Previous studies have reported an association between hyponatremia and vasospasm, however whether hyponatremia directly contributes to the pathogenesis of cerebral vasospasm (CVS), or is a by-product is still unclear. The aim of this study was to explore an association between hyponatremia and CVS after aSAH, and evaluating the temporality of these 2 events. Methods: A retrospective study of consecutive patients with aSAH admitted to the Baylor St.

SUMMARY: Intracranial aneurysms with subarachnoid hemorrhage lead to high morbidity and mortality. It is of critical importance to detect aneurysms, identify risk factors of rupture, and predict treatment response of aneurysms to guide clinical interventions. Artificial intelligence has received worldwide attention for its impressive performance in image-based tasks. Artificial intelligence serves as an adjunct to physicians in a series of clinical settings, which substantially improves diagnostic accuracy while reducing physicians’ workload. Computer-assisted diagnosis systems of aneurysms based on MRA and CTA using...

AbstractAs a result of increased awareness of wide-spread methodological bias and obvious translational roadblocks in subarachnoid hemorrhage (SAH) research, various checklists and guidelines were developed over the past decades. This systematic review assesses the overall methodological quality of preclinical SAH research. An electronic search for preclinical studies on SAH revealed 3415 potential articles. Of these, 765 original research papers conducted in vivo in mice, rats, rabbits, cats, dogs, pigs, goats, and non-human primates with a focus on brain damage related to delayed cerebral vasospasm and early brain injury...

CONCLUSIONS: The effects of case volume and CSC capabilities on in-hospital mortality and short-term functional outcomes in SAH patients differed between patients undergoing clipping and those undergoing coiling. In the modern endovascular era, better outcomes of clipping may be achieved in facilities with high CSC capabilities. PMID: 32168489 [PubMed - as supplied by publisher]
