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.

Perguntas Frequentes

What is the Norton Scale?

The Norton Scale is one of the oldest and most widely used tools for assessing pressure ulcer (bedsore) risk in elderly patients. It evaluates 5 parameters: physical condition, mental condition, activity, mobility, and incontinence. Lower scores indicate higher risk.

What Norton Score indicates pressure ulcer risk?

14-20 = Low risk, 12-13 = Medium risk, <12 = High risk. The maximum score is 20 (lowest risk) and minimum is 5 (highest risk). Patients with scores ≤ 14 require preventive interventions.

How does Norton differ from Braden Scale?

Norton focuses more on physical and functional status, while Braden evaluates specific physiological factors affecting pressure ulcer development (sensory perception, moisture, activity, mobility, nutrition, friction/shear). Braden is more comprehensive for identifying causative factors.

What preventive measures are recommended for high-risk patients?

Reposition every 2 hours, use pressure-redistributing mattresses, maintain skin hygiene and moisture barrier, ensure adequate nutrition and hydration, minimize shear and friction, and conduct daily skin assessments. Individualize based on patient condition.
