Scribing.io Automation

The AI scribe automatically:

• Flags duration of symptoms to ensure < 24 hours

• Identifies resolution language ("symptoms resolved completely")

• Captures temporal markers for onset and resolution

• Tags neurological symptoms

• Maps ABCD2 score components from documentation

• Highlights any contradicting documentation suggesting permanent deficits

Remember to specifically state "transient ischemic attack" or "TIA" rather than using only descriptive terms.
