FLACC score calculator

FLACC (Face, Legs, Activity, Cry, Consolability) assigns 0-2 points to each domain for a total score from 0-10. Higher scores suggest greater likelihood of clinically significant pain.

• Face: relaxed vs occasional frown vs frequent grimace/clenched jaw.
• Legs: relaxed vs uneasy/restless vs kicking or drawn up.
• Activity: lying quietly vs squirming/tense vs arched/rigid/jerking.
• Cry: no cry vs moans/whimpers vs steady or screaming.
• Consolability: content/relaxed vs reassured by touch/talk vs difficult to console.

Bands commonly used: 0 relaxed/comfortable; 1-3 mild discomfort; 4-6 moderate pain; 7-10 severe pain that warrants prompt reassessment and intervention.

Score at rest and, when possible, during movement or care. Reassess after comfort measures or analgesia and document trends over time.

Example: A 3-year-old after an IV attempt has a frequent grimace (Face 2), legs drawn up (Legs 2), tense activity (Activity 1), whimpering (Cry 1), and is consolable only with holding (Consolability 1). Total score = 7, consistent with severe pain and the need for prompt reassessment and intervention.

• Observe quietly for 1-2 minutes before touching the child to capture baseline behavior.
• Score during or after routine care when feasible; some pain behaviors appear only with movement.
• Ask caregivers what is typical for the child, especially for children with neurologic or developmental differences.
• Use the same rater when possible and document context to reduce variability.

1. Set context first: rest vs movement/procedure and recent analgesia timing.
2. Observe all five domains before assigning points.
3. Document total and domain subscores to make reassessment actionable.
4. Treat based on protocol and clinical judgment, then repeat FLACC after intervention.
5. Trend scores over time rather than reacting to one isolated value.

• Originally validated for children about 2 months to 7 years who cannot self-report pain.
• Use as an adjunct in older children with impaired communication; consider the revised FLACC tool for cognitive impairment.
• For children who can self-report, use self-report scales as the primary measure and FLACC as supportive context.

• Neonates and immediate post-op infants often use dedicated neonatal tools (e.g., CRIES).
• Children able to self-report should use Faces or numeric rating scales with FLACC as supportive context.
• Children with cognitive impairment may benefit from the revised FLACC with individualized descriptors.

• Consider age, developmental level, and baseline behavior (e.g., children with neurologic impairment may have different normal movements or tone).
• Document FLACC scores with timing (before/after procedures or analgesia) and the child's activity level.
• Combine with non-pharmacologic comfort measures and institutional analgesia pathways.
• Interpret cautiously in sedated, ventilated, or paralyzed patients where behavioral cues may be blunted.

• Distress from fear, hunger, or environmental stimuli can elevate scores without true pain.
• Single scores are less informative than trends, especially around procedures or medication changes.
• Chronic neurologic conditions may require caregiver input to define baseline behaviors.

• For moderate or severe scores, check reversible causes (positioning, diaper, hunger) and provide comfort measures.
• Escalate analgesia per local protocols if scores remain elevated or rise after interventions.
• Document the score, context, interventions, and response to guide ongoing care.

• After analgesic or comfort intervention: repeat FLACC in the expected response window.
• If stable low discomfort: continue interval reassessment per unit policy.
• If score rises or trajectory worsens: immediate reassessment and escalation.

• Persistent moderate/severe score after expected intervention window.
• Rising distress behaviors with new physiologic instability.
• Large disagreement between raters or unclear baseline behavior interpretation.
• Caregiver concern that behavior differs sharply from baseline between formal checks.

• Fear and procedural anxiety can raise FLACC even when tissue injury pain is limited.
• Sedation can mask expression, cry, and activity domains, falsely lowering total score.
• Chronic neurologic differences may require individualized baseline descriptors (revised FLACC approach).
• A falling score after intervention is often more informative than the initial peak score.

• Record the total score and the individual domain scores.
• Note the context (resting, during a procedure, post-medication).
• List comfort measures or analgesics given and the reassessment time.
• Describe caregiver input about baseline behavior when relevant.

• Current FLACC total plus component-level scores and observation context.
• Interventions delivered and timing relative to reassessment.
• Trend direction compared with prior documented score(s).
• Caregiver baseline-behavior input and any individualized descriptors used.
• Escalation trigger and next reassessment interval.

• CRIES — Neonatal Pain Scale for immediate postoperative neonates.
• Pediatric Vital Signs to interpret heart rate and blood pressure in context.

• FLACC behavioral pain scale (Merkel et al., 1997)
