Dr. Elisabeth Marsh's clinical interest is in cerebrovascular neurology, and her clinical research focuses on stroke outcomes and recovery. Her clinical responsibilities include attending on the inpatient Stroke Service at the Johns Hopkins Hospital and inpatient Neurology Service at the Johns Hopkins Bayview Medical Center. In 2014, Dr. Marsh was named the Medical Director of the Comprehensive Stroke Program at the Johns Hopkins Bayview Medical Center. She implemented the Bayview Stroke Intervention Clinic (BaSIC), a multi-disciplinary follow-up clinic designed to promote patient follow-up, reduce hospital readmission rates, and enhance post-stroke recovery. Her current focus is on the under-reported neurologic deficits (particularly with respect to depression, fatigue, and cognition) that significantly impair long-term functional outcome and patient satisfaction, despite scores on metrics such as the NIH stroke scale that indicate a “good recovery”. She leads a team of vascular neurologists, emergency medicine physicians, neurosurgeons, interventional neuroradiologists, neurointensivists, and rehabilitation specialists, who work together to provide the highest level of care to all stroke patients, resulting in better functional outcomes and improved quality of life. She is also interested in the treatment of acute stroke and intracranial hemorrhage. Her past work has included evaluation of the predictors of hemorrhagic transformation following ischemic stroke. Using multivariable regression, she created a model that predicts rate of hemorrhagic transformation in patients with acute stroke on anticoagulation, the Hemorrhage Risk Stratification (HeRS) score. The tool is available for free through Apple by searching 'Johns Hopkins HeRS score' in the App Store. Dr. Marsh is rated as an Experienced provider by MediFind in Transmyocardial Revascularization.
