Pain assessment across developmental and cognitive abilities
Also known as Paediatric pain assessment · FLACC and revised FLACC · Faces Pain Scale-Revised · Self-report of pain intensity in children · Pain assessment in cognitive impairment · NCCPC and non-verbal pain tools · Pain as the fifth vital sign
Fellowship-level approach to measuring a child's pain honestly across every age and ability: self-report as the gold standard from about four years with the Faces Pain Scale-Revised and the Numerical Rating Scale from about eight years; behavioural observation with FLACC for the two-month to seven-year-old who cannot self-report; individualised observational tools (revised FLACC, Non-communicating Children's Pain Checklist) for children with cognitive impairment or communication disability; COMFORT-behaviour in the PICU; the developmental and cognitive logic that picks the right tool; the traps that undertreat pain (the quiet child, the paralysed child, the child whose behaviour has habituated); and the ANZ, UK and North American standard that pain is the fifth vital sign, reassessed after every intervention and documented in the chart.

Red flags
- Defaulting to a behavioural score for a child who can self-report — the child's own report is the gold standard; observational tools estimate pain only for those who cannot or will not tell you
- Reading a quiet, still, withdrawn child as comfortable — immobility, a flat affect, a freeze response or sleep can mark severe pain, especially in the postoperative, cognitively impaired or critically ill child; absence of behavioural signs is not absence of pain
- Using a Faces scale for a child who cannot map an abstract face onto their own internal state — children under about four years and many with cognitive impairment cannot reliably use self-report scales, and a number they offer may be a guess or a bid to please
- Applying a generic FLACC to a child with cerebral palsy, dystonia or a movement disorder without individualising the items — spasticity, contractures and baseline dyskinesia corrupt the Legs and Activity domains, so you use the revised FLACC and fold in parent-described baseline behaviour
- Reading a single low score in isolation for a child on opioids, sedatives or paralysing agents — sedation and neuromuscular blockade suppress the behavioural and physiological signs FLACC and COMFORT rely on, so a low score can coexist with untreated pain
- Assessing pain once and never again — pain is the fifth vital sign; reassess after every analgesic intervention against the response you expected, and escalate when the trajectory is wrong
- Accepting a carer's reassurance that a non-verbal child is always 'like this' without scoring against a validated tool and the child's own baseline — baseline change, not baseline level, is the signal

Overview & Definition
A two-year-old is brought to the emergency department after a scald and lies still and silent on the trolley while the team prepares to clean the burn. A registrar glances over, sees no crying, and writes "comfortable." An hour later the nurse scores the child with FLACC and gets seven out of ten, and morphine is given that should have been given at the door. That gap — between the pain a child is in and pain team records — is what this page exists to close. The cleaning and the dressing of the burn live on another page. What lives here is the disciplined, repeatable measurement of a child's pain across every age and every ability, because pain that is not measured is pain that is not treated. [2]
Pain assessment is the act of assigning a reproducible intensity score to a child's pain using a validated instrument matched to their developmental age and communication ability, recording it as a routine observation, and acting on it. [4] Two ideas hold the field together. The first is that self-report is the gold standard: whenever a child can understand the task and communicate an answer, their own rating of their pain is the measure you act on, and observational tools are a fallback that estimates pain only for those who cannot tell you. The second is the developmental and cognitive match: a Faces scale handed to a three-year-old, a generic FLACC applied to a child with dystonia, or a COMFORT score read in isolation on a paralysed child are all the same mistake in different clothing — a good tool used on the wrong patient. [6]
The discipline carries three obligations. Assess with the right tool, reassess after every intervention, and document so that the next clinician inherits a trajectory rather than a single number. Pain is the fifth vital sign, and the pages on neonatal pain, procedural pain, and acute and chronic pain management build on the scores you produce here. [2]
