Which factor is most strongly associated with non-accidental trauma in a pediatric patient?

• A. Inconsistent history with injuries.
• B. Delays in seeking care.
• C. Injuries in unusual locations.
• D. Multiple injuries at different healing stages.

Answer: (A)

Inconsistent or implausible explanations for injuries is the strongest red flag for non-accidental trauma. When the story given by caregivers doesn’t fit what is seen—the mechanism doesn’t plausibly produce the injury, or the narrative changes with questions—the mismatch suggests the injuries may not be accidental. This direct inconsistency is more predictive of abuse than other signs because it targets the reliability of the account itself, which is a key clue clinicians use to differentiate abuse from accidents.

Delays in seeking care, injuries in unusual locations, and multiple injuries at different healing stages can raise concern, but they can occur for reasons other than abuse (such as access barriers, atypical accident patterns, or independent injuries). The core idea is that a narrative-injury mismatch is the most telling indicator of potential non-accidental trauma and should prompt careful documentation and appropriate safeguarding actions.
