AbstractOf the 750,000 strokes in the United States every year, 15% patients suffer from hemorrhagic stroke. Intracerebral hemorrhage (ICH) is a subtype of hemorrhagic stroke. Despite advances in acute management, patients with hemorrhagic stroke continue to suffer from high mortality and survivors suffer from multidomain impairments in the physical, cognitive, and mental health domains which could last for months to years from their index stroke. Long-term prognosis after ICH is critically dependent on the quality and efficacy of care a patient receives during the acute phase of care. With ongoing care consolidation in stroke systems of care, the number of ICH patients who need to undergo interhospital transfers (IHTs) is increasing. However, the associations between IHT and ICH outcomes have not been well described in literature. In this review, we describe the epidemiology of IHT for ICH, the relationship between IHT and ICH patient outcomes, and proposed improvements to the IHT process to ensure better long-term patient outcomes. Our review indicates that evidence regarding the safety and benefit of IHT for ICH patients is conflicting, with some studies reporting poorer outcomes for transferred patients compared to direct admissions via emergency rooms and other studies showing no effect on outcomes. The American Heart Association guidelines for ICH provide recommendations for timely blood pressure control and anticoagulation reversal to improve patient outcomes. The American Heart Association stroke systems of care guidelines provide recommendations for transfer agreements and but do not provide details on how patients should be managed while undergoing IHT. Large, prospective, and multicenter studies comparing outcomes of IHT patients to direct admissions are necessary to provide more definitive guidance to optimize IHT protocols and aid clinical decision-making.Copyright © 2024 Elsevier Inc.
