SINBAD Diabetic Foot Ulcer Score

SINBAD diabetic-foot-ulcer score (Ince 2008): Site, Ischemia, Neuropathy, Bacterial infection, Area, and Depth, each 0/1; total 0-6, with >= 3 predicting a poorer outcome.

Example

Site: mid- or hindfoot
Yes
Ischemia
Yes
Neuropathy
Yes

Result: SINBAD 3 of 6 — higher risk of poor outcome (>= 3).

The tool opens with these values already filled in. Replace them with your own.

What the result means

< 3
Lower risk.
>= 3
Higher risk of non-healing / amputation (Site + Ischemia + Neuropathy + Bacterial infection + Area + Depth, each 0/1). A prognostic score, not a diagnosis.

What you enter

  • Site: mid- or hindfoot (vs forefoot)
  • Ischemia: pedal pulses absent
  • Neuropathy: protective sensation lost
  • Bacterial infection present
  • Area >= 1 cm^2
  • Depth: reaches muscle/tendon/bone
