Applying a knowledge translation framework for triaging low back pain and radicular pain at an emergency department: an iterative process within an uncontrolled before-and-after design.

Implementation of a new protocol in a tertiary hospital ED with high turn over of rotating trainees is a challenge and requires ongoing efforts to ensure sustainability. Rates of imaging represent an indirect though useful indicator. We have demonstrated that it is possible to implement a protocol that includes demedicalisation in an ED environment and to observe changes in indicator results.
