Scribing.io Automation

The AI scribe automatically identifies key phrases such as:

• "Anterior knee pain localized to patellar tendon"

• "Pain worse with jumping/landing activities"

• "Tenderness at inferior pole of patella"

• Captures specific measurements of tendon thickness if documented

• Tags chronicity markers in patient history

• Identifies and links related physical examination findings

Tip: Include objective findings like "point tenderness at inferior pole of patella" to strengthen documentation specificity.
