Description
This skill provides structured guidance for common ED decision rules used to reduce unnecessary imaging or testing while maintaining safety. It supports accurate input collection, rule application, and risk interpretation.
Quick Reference
| Tool | Use |
|---|---|
| Ottawa Ankle Rules | Decide ankle or foot radiographs after ankle injury |
| Ottawa Knee Rules | Decide knee radiographs after acute knee injury |
| Canadian C-Spine Rule | Decide cervical spine imaging in alert trauma patients |
| PERC Rule | Exclude PE in low-risk patients without D-dimer |
Interactive Mode (Lightweight)
- Confirm clinical context and intended rule.
- Collect required inputs and findings.
- Validate inclusion and exclusion criteria.
- Apply rule and present result.
- Provide safety caveats and next-step guidance.
Decision Rules
Safety and Limitations
- Support tool only; not diagnostic or prescriptive.
- Use local policies and clinical judgment.
- Validate eligibility before applying each rule.

Emergency Decision Rules provides structured guidance for applying validated ED decision rules to reduce unnecessary imaging while maintaining safety. It covers Ottawa Ankle and Knee rules, the Canadian C-Spine Rule, and the PERC rule, with input collection, criteria checks, and risk interpretation.
How This Skill Works
In interactive mode, you confirm the clinical context, collect required inputs, validate inclusion criteria, apply the chosen rule, and present the result with safety caveats and next-step guidance. The tool supports structured input, rule-specific criteria, and interpretation to aid clinical decision-making.
When to Use It
- Suspected ankle injury where radiographs are considered and Ottawa Ankle Rules may apply
- Acute knee injury where radiographs are being considered and Ottawa Knee Rules may apply
- Alert trauma patient where cervical spine imaging is in question and the Canadian C-Spine Rule should be used
- Low-risk patient with possible PE where PERC Rule could exclude PE without D-dimer
- General ED imaging decision support requiring validated decision rules before imaging
Quick Start
- Step 1: Confirm clinical context and choose the rule (Ottawa Ankle/Knee, Canadian C-Spine, or PERC)
- Step 2: Collect required findings and inputs per the selected rule
- Step 3: Apply the rule, review the result, and note safety caveats and next steps
Best Practices
- Confirm the clinical context and select the appropriate rule before input collection
- Verify that patient data meet the rule's inclusion and exclusion criteria
- Use local policies and clinical judgment to interpret results
- Document inputs, rule result, and rationale clearly in the chart
- Present safety caveats and recommended next steps after applying the rule
Example Use Cases
- Applying Ottawa Ankle Rules to determine need for foot radiographs after an inversion injury
- Using Ottawa Knee Rules to avoid knee x-ray in a patient with non-severe, non-mobile pain
- Applying Canadian C-Spine Rule to decide cervical imaging in alert trauma patients
- Using PERC Rule to exclude pulmonary embolism in a low-risk patient without D-dimer
- Documenting rule-based decisions in the ED with safety notes and follow-up plans
