What is the classification system for pressure injuries?

The classification system for pressure injuries is based on stages I-IV, which reflects the extent of tissue involvement in the injury. This system is crucial for understanding the severity of the pressure injury and guiding treatment.

Each stage indicates the depth and characteristics of the damage:

• Stage I represents non-blanchable erythema of intact skin, which indicates potential damage to the skin.

• Stage II involves partial-thickness loss of skin with exposed dermis, indicating a deeper level of damage that still involves some intact skin.

• Stage III denotes full-thickness skin loss, where adipose tissue may be visible, reflecting a more severe injury.

• Stage IV shows full-thickness skin and tissue loss, with exposed bone, tendon, or muscle, indicating profound tissue damage.

This staging system helps healthcare providers assess the injury accurately and implement appropriate interventions based on the severity and healing stages of the pressure injury. This classification directly informs the treatment plan and interventions required for healing.
