FLACC Scores


A frequent challenge in pediatrics is assessing pain in children who are non-verbal. Part of this population is unable to report the location and degree of their pain because of chronological age, i.e. an infant or toddler. Another significant group is the population of children with cognitive impairment that is severe enough to impair their expressive language. This population includes but is not limited to children with severe cerebral palsy, developmental delay, or mental retardation.

The FLACC score has been validated for measuring postoperative pain in children with mild to severe cognitive impairment. It has also been validated for the assessment of pain secondary to surgery, trauma, cancer or other painful diseases for all pre-verbal children (including infants).

In the diagram below are the categories for scoring. Zero, one or two points is assigned to each of the five categories shown in the table: Face, Legs, Activity, Cry, and Consolability (hence the term, FLACC). Total points assigned may be from zero to ten.

As discussed above, the numeric rating scale may be categorized into no pain, mild pain, moderate pain, and severe pain based on the 0-10 self report scale. The categories guide analgesic selection when the score is obtained by self-report. In contrast, the total FLACC score (0-10) cannot be converted to these descriptive groupings. The score should be contextualized to the particular patient, the clinical setting and his/her primary caregiver's perception of the child's behavior. A patient with developmental delay may need an opioid for pain relief but have a FLACC score that is less than seven.
