Summary
The overall goal of the Lumbar Image Reporting with Epidemiology (LIRE) is to perform a large, pragmatic, cluster randomized controlled trial to determine the effectiveness of a simple, inexpensive and easy to deploy intervention - insertion of epidemiological benchmarks into lumbar spine imaging reports - at reducing subsequent tests and treatments. The investigator's main hypothesis is that for patients referred from primary care providers, inserting epidemiological evidence in lumbar spine imaging reports will reduce subsequent diagnostic and therapeutic interventions, including cross-sectional imaging (MR/CT), opioid prescriptions, spinal injections and surgery.
