Norton scale (nort′ŏn)
A scale used to predict the likelihood a patient will develop pressure ulcers. The patient is rated from 1 (low risk) to 4 (high risk) using the following five criteria: physical condition, mental condition, activity, mobility, and incontinence. See: table
|Physical Condition||Mental State||Activity||Mobility||Incontinence|
|Fair||3||Apathetic||3||Walks with help||3||Slightly limited||3||Occasionally|
|Poor||2||Confused||2||Chairbound||2||Very limited||2||Usually urinary||2|
* The patient is rated from 1 to 4 on the five risk factors listed. A score of ≤14 indicates risk for decubitus ulcers, or pressure sores. SOURCE: Doreen Norton, Rhoda McLaren, and A.N. Exton-Smith.

Although both the Braden and Norton scales
are validated tools for risk assessment used in the majority of nursing homes, they assess resident risk factors differently.
2005) have recently found out that the Braden scale, the modified Norton scale
and the 4-factor model were not valid as pressure ulcer risk assessment scales for intensive care patients.
Twelve elderly bedridden patients without pressure sores, living in a long-term care unit, but with identical risk for pressure ulcer development according to the Norton Scale
 were also studied.
