The COMFORT Scale is a pain scale that may be used by a healthcare provider when a person cannot describe or rate their pain. Some of the common populations this scale might be used with include:

• children
• cognitively impaired adults
• adults whose cognition is temporarily impaired, by medication or illness
• the learning disabled
• sedated patients in an ICU or operating room setting

The COMFORT Scale provides a pain rating between 9 and 45.
