BACKGROUND AND PURPOSE:Prediction of hemorrhagic transformation in acute ischemic stroke could help determine treatment and prognostication. With increasing numbers of patients with acute ischemic stroke undergoing multimodal CT imaging, we examined whether CT perfusion could predict hemorrhagic transformation in acute ischemic stroke.

Introduction: Conflicting data exist regarding the association between the length of stay (LOS) of critically ill patients in the emergency department (ED) and their subsequent outcome. However, such patients are an overall heterogeneous group, and we therefore sought to study the association between EDLOS and outcomes in a specific subgroup of critically ill patients, namely those with acute ischemic stroke/transient ischemic attack (AIS/TIA).Methods: This was a retrospective review of adult patients with a discharge diagnosis of AIS/TIA presenting to an ED between July 2009 and February 2010. We collected demographics, EDLOS, arrival stroke severity (National Institutes of Health Stroke Scale - NIHSS), intravenous tissue plasminogen activator (IV tPA) use, functional outcome at discharge, discharge destination and hospital-LOS. We analyzed relationship between EDLOS, outcomes and discharge destination after controlling for confounders.Results: 190 patients were included in the cohort. Median EDLOS was 332 minutes (Inter-Quartile Range -IQR: 250.3–557.8). There was a significant inverse linear association between EDLOS and hospital-LOS (p=0.049). Patients who received IV tPA had a shorter median EDLOS (238 minutes, IQR: 194–299) than patients who did not (median: 387 minutes, IQR: 285–588 minutes; p<0.0001). There was no significant association between EDLOS and poor outcome (p=0.40), discharge destination (p=0.20), or death (p=0.44). This remained true even after controlling for IV tPA use, NIHSS and hospital-LOS; and did not change even when analysis was restricted to AIS patients alone.Conclusion: There was no significant association between prolonged EDLOS and outcome for AIS/TIA patients at our institution. We therefore suggest that EDLOS alone is an insufficient indicator of stroke care in the ED, and that the ED can provide appropriate acute care for AIS/TIA patients.

This annual 5-day Continued Medical Education event featured the latest in new treatment strategies and techniques for orthopedists, neurosurgeons, physiatrists, primary care providers and other professionals involved in treating patients with spinal disorders. This year's program content focused on: minimally invasive surgery, motion-preservation surgery, nonoperative spine care, value (quality/cost) and maintenance of certification self-assessment examination.
