title: A comparison of opioid use between WCB recipients and other Manitobans for knee, shoulder, back and carpal tunnel release procedures.
abstract: BACKGROUND
  This study's objectives were to evaluate whether WCB claimants with conditions requiring certain surgical procedures are more likely to be prescribed outpatient opioids than other Manitobans and whether those prescribed opioids are more likely to still be on opioid medications 6 months post procedure.
  
  
  METHODS
  We compared 7,246 WCB claims for a number of surgical procedures to 65,032 similar procedures performed in other Manitobans. Logistic regression was used to explore the association between being a WCB claimant and being prescribed opioids, while controlling for type of surgical procedure and other potential confounders.
  
  
  RESULTS
  WCB claimants were more likely than other Manitobans to be prescribed opioids (adjusted OR 1.38; 95%CI 1.30-1.47). Amongst those prescribed opioids, the odds of being still on opioids 6 months post-procedure were not significantly elevated for WCB claimants (adjusted OR 1.09 95%CI 0.97-1.23).
  
  
  CONCLUSIONS
  WCB claimants are prescribed opioids more often than non-claimants for similar procedures.
