About Norton Scale
The Norton Scale assesses pressure ulcer risk in hospitalized patients using 5 criteria scored 1-4 each. Total score: 5-20 points. Lower scores indicate higher risk. Validated tool for pressure injury prevention planning.
Each criterion is scored from 1 (highest risk) to 4 (lowest risk), with total scores ranging from 5-20 points. Scores of 14 or below indicate significant risk for pressure ulcer development and require preventive interventions. The scale is widely used in acute care, long-term care, and rehabilitation settings.
