Pain scale

A pain scale measures a patient's pain intensity or other features. Pain scales are a common communication tool in medical contexts, and are used in a variety of medical settings. Pain scales are a necessity to assist with better assessment of pain and patient screening. Pain measurements help determine the severity, type, and duration of the pain, and are used to make an accurate diagnosis, determine a treatment plan, and evaluate the effectiveness of treatment.[medical citation needed] Pain scales are based on trust, cartoons (behavioral), or imaginary data, and are available for neonates, infants, children, adolescents, adults, seniors, and persons whose communication is impaired. Pain assessments are often regarded as "the 5th vital sign".[1]

A patient's self-reported pain is so critical in the pain assessment method that it has been described as the "most valid measure" of pain.[2][3] The focus on patient report of pain is an essential aspect of any pain scale, but there are additional features that should be included in a pain scale. In addition to focusing on the patient's perspective, a pain scale should also be free of bias, accurate and reliable, able to differentiate between pain and other undesired emotions, absolute not relative, and able to act as a predictor or screening tool.[2]

Numeric rating scale

The Numeric Rating Scale (NRS-11) is an 11-point scale for patient self-reporting of pain. It is based solely on the ability to perform activities of daily living (ADLs) and can be used for adults and children 10 years old or older.[48]

Rating Pain Level
0 No Pain
1–3 Mild Pain (nagging, annoying, interfering little with ADLs)
4–6 Moderate Pain (interferes significantly with ADLs)
7–10 Severe Pain (disabling; unable to perform ADLs)

Pain interferes with a person's ability to perform ADLs. Pain also interferes with a person's ability to concentrate, and to think. A sufficiently strong pain can be disabling on a person's concentration and coherent thought, even though it is not strong enough to prevent that person's performance of ADLs. However, there is no system available for measuring concentration and thought.
