NPIAP Pressure Injury Staging
NPIAP pressure injury staging (2016 revision) — the standard classification of a pressure injury by depth of tissue loss.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Pressure injury stage
- Stage 3 - full-thickness skin loss (fat may be visible)
Result: NPIAP Stage 3 pressure injury: full-thickness skin loss; subcutaneous fat may be visible, but fascia, muscle, tendon, and bone are not exposed.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Stage 1 / 2
- 1: non-blanchable erythema, intact skin. 2: partial-thickness loss with exposed dermis.
- Stage 3 / 4
- 3: full-thickness skin loss (fat may show). 4: full-thickness loss with exposed fascia / muscle / bone.
- Unstageable / DTPI
- Unstageable: full-thickness loss obscured by slough or eschar. DTPI: persistent non-blanchable deep discoloration.
