Imaging for patients presenting to an emergency department with back pain: Impact on patient pathway.

This study provides benchmark data on the use of imaging for back pain in an Australian ED, an area which has been largely unexplored. The rate of imaging in the ED was higher than previously reported in a General Practice setting. Consistent with guidelines, patients older than 70 were more than twice as likely to receive imaging compared to younger patients. It was beyond the scope of the current study to determine whether these images were clinically indicated and further research is required to determine if initiatives to reduce imaging in this population are warranted.
