Large Variation in Provincial Guidelines for Urine Drug Screening during Opioid Agonist Treatment in Canada

Urine drug screening (UDS) is commonly used to detect or validate self-reported substance use, particularly when beginning and maintaining opioid agonist therapy (OAT). However, there is currently no summary of the published clinical practice guidelines for UDS in Canada, and no measure of the consistency with which different provinces suggest administering UDS. Therefore, we conducted a policy scan of UDS guidelines, examining the published clinical practice guidelines for each Canadian province and extracting all relevant data in March 2017. Our Canadian guideline and policy scan found that UDS frequency recommendations vary greatly among Provinces for persons receiving OAT for opioid use disorder.
