VA Stroke Study: neurologist care is associated with increased testing but improved outcomes

Area of Science:

• Neurology
• Clinical Medicine
• Health Services Research

Background:

• Ischemic stroke is a leading cause of death and disability worldwide.
• Effective management strategies are crucial for improving patient outcomes.
• The role of neurologist management in ischemic stroke care requires further investigation.

Purpose of the Study:

• To analyze VA Stroke Study (VASt) data to determine if neurologist management impacts the process and outcomes of ischemic stroke care.
• To compare testing, hospitalization, and discharge status between patients managed by neurologists and non-neurologists.

Main Methods:

• Prospective analysis of VASt data from nine VA hospitals (April 1995-March 1997).
• Inclusion of 775 ischemic stroke patients admitted from home.
• Comparison of demographics, stroke severity (Canadian Neurologic Score), stroke subtype (TOAST classification), tests/procedures, and discharge status (Rankin scale) between neurologist and non-neurologist care groups.

Main Results:

• Neurologists ordered more advanced imaging (MRI, cerebral angiography) and specialist consultations (speech, occupational therapy).
• No significant differences were observed in stroke severity, subtype, age, or hospitalization duration between groups.
• Patients under neurologist care had significantly lower mortality (5.6% vs 13.5%) and combined death/dependency rates (46.1% vs 57.1%) at discharge, even after adjusting for stroke severity and comorbidities.

Conclusions:

• Neurologist management of ischemic stroke is associated with more comprehensive diagnostic testing.
• This specialized care leads to improved patient outcomes, specifically reduced mortality and dependency.
• Neurologist care offers a survival and functional benefit without prolonging hospitalization.
