Interventions to reduce imaging in children with upper or lower extremity injuries: a systematic review and meta-analysis
For pediatric extremity injuries, integrating validated decision rules, especially for ankles, appears effective at reducing unnecessary radiographs. Remember that while guidelines are helpful, the evidence base is strongest for ankle and wrist protocols; do not extrapolate these findings to other injury patterns without further data. Always be mindful of potential bias in the existing literature.
This systematic review and meta-analysis synthesized evidence regarding interventions designed to curb unnecessary radiographic imaging in pediatric patients presenting with upper or lower extremity injuries in the emergency department. The authors found that implementing specific clinical decision rules showed promise for reducing radiation exposure, transition delays, and costs associated with over-imaging. Notably, a decision rule tailored for ankle injuries was associated with a significant reduction in radiography (OR=0.11), and a similar rule for wrist injuries demonstrated a reduction (OR=0.06). While the overall findings support the utility of evidence-based guidelines, the review cautioned that more research is needed to validate these approaches across other types of extremity trauma and to pinpoint the most effective implementation strategies within the ED setting.
