About the ROSIER Score
The ROSIER (Recognition of Stroke In the Emergency Room) scale is a validated tool designed to identify patients presenting to the Emergency Department who are most likely to have had a stroke or TIA, guiding prompt diagnosis and management.
Interpretation Guide:
- Score > 0: Indicates a high probability of stroke. These patients require urgent diagnostic imaging and specialist referral.
- Score = 0: The probability of stroke is lower, but still warrants further investigation, especially if clinical suspicion remains high.
- Score < 0: Stroke is unlikely. The symptoms are more likely to be due to stroke mimics like syncope or seizure.
Source: The ROSIER score was developed and validated in the UK, demonstrating high sensitivity for stroke detection in the pre-hospital and emergency setting.
