Observation cuts CT in paediatric abdominal trauma

Emergency Department Observation and Computed Tomography Use in Children With Blunt Abdominal Trauma
Annals of Emergency Medicine · Added 27 July 2026

Observation with deferred CT decisionmaking was associated with less frequent CT use, particularly in patients with intermediate clinician suspicion, without an increase in missed injuries.

Study type

Cohort

Design

Secondary analysis of prospective multicentre cohort

Participants

7,442 children with blunt abdominal trauma; 2,024 observed

Main finding

CT use 20.5% in observed vs 37.1% non-observed (difference 16.7%, 95% CI 14.5–18.8%); observation associated with lower CT use at intermediate suspicion (e.g. OR 0.15, 95% CI 0.10–0.23 for 6–10% suspicion); 79.5% observed patients discharged without CT and none had injury needing acute intervention (0%, 95% CI 0–0.3%).

Caveat

Observational design; observed patients had lower baseline injury risk, suggesting selection bias

Bottom line

Supports current practice

Learning goal

Weigh the risks and benefits of observation before CT when assessing children with blunt abdominal trauma.
