Corey Fehnel MD, MPH is a neurointensivist specializing in the critical care of diseases affecting the nervous system. His research focus lies in the intersection of neurology health services, aging and palliative care. Dr. Fehnel uses the tools of health services research to better describe outcomes among older persons with critical neurological illness. Using nationwide Medicare datasets he establishes trends in utilization, and identifies key determinants associated with favorable and unfavorable outcomes. As an attending neurointensivist at Beth Israel Deaconess Medical Center, the needs of his patients guide his research questions at the intersection of aging and acute brain injury. His previous work has examined prediction modeling of hospital readmission after acute ischemic stroke, as well as outcomes and location of long-term care among older patients receiving decompressive hemicraniectomy (removal of a portion of the skull) for severe ischemic stroke. He has also defined hospital characteristics associated with outcome and quality of care for older patients with aneurysmal subarachnoid hemorrhage. 

Dr.Fehnel also cares for patients in Port au Prince in collaboration with the St. Luke Foundation for Haiti.
