🦶 PEDIS / IDSA-IWGDF Diabetic Foot Infection Grade
UseWhen to use: clinically suspected diabetic foot infection after wound assessment.
StrataHigher grades need faster escalation, imaging and often IV therapy/surgery.
LimitsWhen not to use: as the sole ischaemia or osteomyelitis rule-out. · Pitfall: undertreating ischaemic infected feet without vascular asses… · Always evaluate PAD and offloading.

Infection grade ≠ perfusion grade.
When to use
When to use: clinically suspected diabetic foot infection after wound assessment.
How it works
1 uninfected; 2 mild (≤2 cm erythema, skin/subcut); 3 moderate (deeper or >2 cm / deeper structures); 4 severe (local infection + SIRS).
Key points
- Infection grade ≠ perfusion grade.
- Grade 4 is an emergency.
- Next: culture strategy, imaging, revascularisation pathways; CN diabetic-foot guideline on zh.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Infection grade (clinical) | 2 — Mild: skin/subcutaneous only; erythema ≤ 2 cm |
|---|
→PEDIS infection grade2
- Class：Mild infection
- Next-step focus：Often outpatient oral antibiotics covering typical skin flora per local guidance; reassess rapidly.
| Infection grade (clinical) | 1 — Uninfected (no systemic or local infection signs) |
|---|
→PEDIS infection grade1
- Class：Uninfected
- Next-step focus：No antimicrobial therapy for infection; optimise ulcer care and offloading.

FAQ
Frequently asked questions
- Does PEDIS / IDSA-IWGDF Diabetic Foot Infection Grade upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is PEDIS / IDSA-IWGDF Diabetic Foot Infection Grade calculated in practice? Can you show a worked example?
- Inputs: Infection grade (clinical) 2 — Mild: skin/subcutaneous only; erythema ≤ 2 cm → Result: PEDIS infection grade 2（Class: Mild infection, Next-step focus: Often outpatient oral antibiotics covering typical skin flora per local guidance; reassess rapidly.） Inputs: Infection grade (clinical) 1 — Uninfected (no systemic or local infection signs) → Result: PEDIS infection grade 1（Class: Uninfected, Next-step focus: No antimicrobial therapy for infection; optimise ulcer care and offloading.）
