title: Implementing evidence-based guidelines for radiography in acute low back pain: a pilot study in a chiropractic community.
abstract: OBJECTIVE
  To evaluate the ability of a systematic educational intervention strategy to change the plain radiography ordering behavior of chiropractors toward evidence-based practice for patients with acute low back pain (LBP).
  
  
  METHODS
  A quasi-experimental method was used comparing outcomes before and after the intervention with those of a control community.
  
  
  METHODS
  Two communities in southern Ontario.
  
  
  METHODS
  Mailed survey data on the management of acute LBP. Outcome Measures Plain radiography use rates for acute LBP based on responses to mailed surveys.
  
  
  RESULTS
  Following the intervention, there was a 42% reduction in the self-report need for plain radiography for uncomplicated acute LBP (P <.025) and a 50% reduction for patients with acute LBP < 1 month (P <.025) in the intervention community. There was no significant change in the self-report need for plain radiography in the control community (P >.05).
  
  
  CONCLUSIONS
  The educational intervention strategy used in this study appeared to have an effect in reducing the perceived need for plain radiography in acute LBP.
