What is numerical pain rating scale?

The Numerical Rating Scale (NRS) for pain is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0 to 10 integers) that best reflects the intensity of their pain. The common format is a horizontal bar or line.

What is numerical pain scale?

How are numerical ratings calculated?

Decimal Score (Item Rating/Maximum Rating) The section maximum numeric rating is 5, so the formula to calculate the section rating is: (Total Decimal Score) / (Total Maximum Decimal Score) x (Maximum Numeric Rating from Section Rating Model), or in this example: (4.4 / 6) x 5 = 3.67.

What is a percentage change in NPRS?

Percent change in NPRS rather than raw score change may provide more meaningful information regarding a patient’s response to pain treatment. For example, a change from 3/10 pain to 0/10 pain may be more meaningful than a change from 8/10 pain to 5/10 pain.

What is the scale of pain?

Numeric pain rating scale [50] is a 11-point scale, graphically or verbally delivered, where the end points are the extremes of no pain and worst pain.

What is a numerical rating scale?

A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0–10 where 0 is no pain and 10 is the worst pain imaginable ( Fig. 13.3 ). Commonly used NRS are 11 point (0–10), 21 point (0–20) and 101 point (0–100) ( Jensen & Karoly 2001 ). Jensen et al (1996) used a 101-point scale on 124 chronic pain patients and found that 90–98% of patients used the scale in multiples of five (equivalent to a 21-point scale). Over 50% of subjects rated their pain in multiples of 10 (equivalent to an 11-point scale). They concluded that 11- and 21-point scales were sensitive enough to measure chronic pain. Kwong & Pathak (2007) found that an 11-point scale for measuring intensity of migraine was 55% more sensitive than a 4-point scale (none, mild, moderate, severe) in detecting clinically important differences. Numerical rating scales may be administered verbally, where patients are asked to rate their pain and the therapist records the value. They may also be applied in written form, completed independently by the patient, either as a single rating or where the numbers are written in ascending order and the patient is asked to circle or select the number corresponding to their pain. Advantages of NRS are that they are easily understood and quickly administered. They have been reported to be sensitive to change and correlate well with other pain intensity measures ( Jensen & Karoly 2001 ). They do not appear to have ratio properties, meaning that a rating of 10, for example, does not necessarily indicate twice as much pain as a rating of five.

What is the weakness of the NRS?

The principal weakness of the NRS is that, statistically, it does not have ratio qualities. That is, numerically equal intervals on the scale (e.g., the difference between 1 and 3 and the difference between 7 and 9) may not represent equivalent intervals in terms of scaling the intensity of pain.

What is a category scale?

When deciding which scale to use, healthcare professionals may consider: 1 The patient’s age or literacy level: Children and people with low literacy levels can find it easier to rate their pain using purely visual scales. Healthcare professionals may prefer to use a numerical or verbal rating scale when assessing pain levels in adults. 2 Cognitive ability: Similarly, people with cognitive impairments may find it easier to use a faces scale. Facial expressions can be easier for people to understand if they are in shock following an injury, taking strong pain medication, or have difficulty speaking. 3 Their field or specialism: Some pain scales may be more useful than others depending on a doctor’s specialism. For example, someone working in an emergency department may prefer to use unidimensional scales, as they provide faster results. However, an oncologist may choose a multidimensional scale, so they can fully understand how cancer affects a person’s life.
