Transient ischemic attack. Improvements in imaging techniques like MRI have likewise begun to shift how stroke patients are treated. For example, Dr. Likosky says, medicine is moving away from a time-based definition of transient ischemic attack (TIA), in which symptoms resolve within 24 hours, to a tissue-based definition. Recent MRI imaging has uncovered evidence of a new infarction in more than half of patients initially diagnosed with TIA.10

“If they do have an infarction on their scan, even if they had symptoms that only lasted for five minutes, that’s a stroke,” Dr. Josephson says. And even a true TIA, he says, represents “a kind of stroke where you got really lucky and you’re not left with deficits, but the risk is still very high.” Accordingly, more patients with TIA are being admitted to the hospital to receive a full workup and preventive treatment. “We think that by evaluating these people urgently, we can reduce the risk of having a stroke by maybe 75% over a three-month time period,” Dr. Josephson says.
Hemorrhagic stroke. To date, the vast majority of patients with hemorrhagic stroke (which accounts for only 13% of all stroke cases) have been managed by neurosurgeons and neurologists. But here, too, Dr. Likosky says the picture could be changing. Recent findings that surgical treatment of intracranial hemorrhaging might not benefit many patients could shift the care paradigm toward a medical management strategy that involves more hospitalists.
Innovations Aplenty
The increasing complexity of stroke care and uneven distribution of resources and expertise have helped fuel several important innovations in delivery, most notably telestroke and neurohospital medicine. Both are being driven, in part, by an increased awareness of time-sensitive interventions and a frequent lack of on-site neurologists at smaller and more rural facilities. If telestroke programs are expanding the reach of neurologists, neurohospitalists are helping to fill the gaps in inpatient stroke care.
Amid the changes, one element is proving a necessary constant: a team approach that relies heavily on the HM emphasis on quality metrics, intensive monitoring, and careful coordination. Who better to lead the charge than hospitalists, says Mary E. Jensen, MD, professor of radiology and neurosurgery at the University of Virginia in Charlottesville. “They’re the ones who are in the hospital, and when these patients go bad, they go bad fast,” she says.
More broadly, Dr. Jensen says, hospitalists should get in on the ground floor when their facility seeks certification as a primary or a comprehensive stroke center. “And they need to make sure that the hospital isn’t just trying to get the sexy elements—the guy with the cath or the gal with the cath who can pull the clot out—but that they have a complete program that involves the care of the patient after they’ve had the procedure done,” she says.
As healthcare reform efforts are making clear, the responsibility doesn’t end after discharge, either. The Affordable Care Act includes a hospital readmission reduction program that will kick in this October, with penalties for hospitals posting unacceptably high 30-day readmission rates. Amy Kind, MD, PhD, assistant professor of medicine in the Division of Geriatrics at the University of Wisconsin School of Medicine and Public Health in Madison, is convinced that a key contributor to high rehospitalization rates among stroke patients may be the woefully incomplete nature of discharge communication.
