Pressure injury staging
The National Pressure Ulcer Advisory Panel (NPUAP)  serves as the authoritative voice for improved patient outcomes in pressure injury prevention and treatment through public policy, education and research. NPUAP redefined pressure injuries and staging during the NPUAP 2016 Staging Consensus Conference that was held in April 2016.

Pressure injury definition - NPUAP

“A pressure injury is localized damage to the skin and underlying soft tissue usually over a bony prominence or related to a medical or other device. The injury can present as intact skin or an open ulcer and may be painful. The injury occurs as a result of intense and/or prolonged pressure or pressure in combination with shear. The tolerance of soft tissue for pressure and shear may also be affected by microclimate, nutrition, perfusion, co-morbidities and condition of the soft tissue.”
