Score | Description of epithelial damage |
---|---|
0 | No epithelial disturbances or sloughing of epithelial cells |
1 | Light epithelial damage and disruption – localized loss of tissue integrity and epithelial sloughing over less than 5% of the epithelial surface, which is otherwise contiguous and intact |
2 | Moderate epithelial damage and disruption – Multiple areas of epithelial disturbance representing 5-25% of the total epithelial surface and small regions of sloughing that expose the basal cell layer |
3 | Severe epithelial damage and disruption – Sloughing over large sections of the epithelial surface (> 25%) that exposes the basal cell layer |
