When a child arrives at the emergency department with a hurt arm or leg, doctors must decide quickly if an X-ray is necessary. Many kids end up getting imaging that they might not actually need. This study looked at how using specific clinical decision rules and guidelines can change that process.
Researchers analyzed data from over 7,000 children across eight different studies. They found that using these rules significantly reduced the number of X-rays taken for ankle injuries. For wrist injuries, the rules also led to fewer X-rays, though it is important to note that eight injuries were missed in those cases. Overall, following established clinical guidelines consistently lowered the number of radiographs per patient.
However, the results weren't perfect across the board. In one specific case where triage nurses used a decision rule, imaging actually increased and 16 missed injuries were found. Because some data on quality was missing, these findings show that while rules can help cut down on unnecessary tests, they must be applied carefully to ensure no injury goes unseen.
