Overview

This review shows the low rate of confirmed strokes in hospital activations, indicating a critical need for improved protocols.

Key Points

  • To identify the frequency and nature of stroke activations in a non-acute hospital setting and evaluate the outcomes.
  • Conducted a retrospective review of acute stroke team activations
  • Analyzed data on symptoms, imaging, diagnoses, and interventions
  • Focused on activations from October 2021 to December 2024
  • 346 code strokes were activated; 35.3% confirmed as cerebrovascular events
  • 20.8% were ischemic strokes and 7.2% hemorrhagic strokes
  • 64.7% categorized as stroke mimics, predominantly encephalopathy and delirium
  • Only 1.7% received IV thrombolysis and 2.9% underwent thrombectomy
