Predicts poor functional outcome after intravenous thrombolysis for acute ischaemic stroke.
Overview
Predicts poor functional outcome after intravenous thrombolysis for acute ischaemic stroke.
Clinical Significance
Higher DRAGON scores predict a greater probability of poor functional outcome after IV thrombolysis.
When to Use
- Use as structured clinical decision support when the required data are available and reliable.
How It Is Calculated
- The displayed variables are combined using the published equation, decision rule or weighted point system.
Interpretation
- Higher DRAGON scores predict a greater probability of poor functional outcome after IV thrombolysis.
Worked Example
Enter verified patient data in the displayed units; MedicalC applies the published model.
Limitations
- Risk and classification tools can be misapplied outside their validated population.
- Missing, estimated or non-contemporaneous data may materially change the result.
Clinical Pearls
- Document the inputs, units, date and clinical setting with the result.
- Use serial scores only when the same instrument and measurement method are used consistently.
Common Mistakes
- Using the tool without confirming entry criteria.
- Using approximate or incorrectly converted values.
- Treating a prognostic score as a standalone treatment decision.
