A study published in CMAJ Open shows that emergency physicians contribute significantly to new prescriptions for opioids in Ontario, and that they prescribe opioids at doses which exceed new Canadian guidelines more often than family physicians, who write the most prescriptions for opioids of any individual group.  The impact is that 1 in 200 patients prescribed opioids in emergency departments are subsequently admitted to hospital for opioid toxicity.

The study was led by Dr. Bjug Borgundvaag, Director of the Schwartz/Reisman Emergency Medicine Institute (SREMI) and Emergency Physician at Mount Sinai Hospital, part of Sinai Health System, and researchers at the Ontario Drug Policy Research Network and The Institute for Clinical and Evaluative Sciences (ICES).

Key findings from the study include:

  • More than one third of all new prescriptions by emergency physicians exceed the dose recommended in the new Canadian opioid prescribing guidelines.
  • Emergency physicians are twice as likely to prescribe higher potency drugs as family physicians.
  • New opioid prescriptions for patients not prescribed opioids within the last year are written almost as frequently by emergency physicians as they are by family physicians.
  • Emergency physicians and family physicians frequently prescribe opioids for conditions in which opioids are currently not recommended as the first line of therapy.

This is the first large scale study on opioid prescribing in Ontario emergency departments, with a focus on opioid naive patients -those who did not have an opioid prescription in the previous year. The study used a population based cohort using administrative data from ICES, analyzing prescriptions between 2008 and 2012. Patients were followed until 2014.

“There is an urgent need to better understand opioid prescribing patterns because the outcomes that we are seeing are alarming.  Canada is among the world’s top consumer of prescription opioids and the increase in use is associated with significant patient harm. One in eight deaths of 25-34 year olds in Ontario is the result of prescription opioid overdose, most of which is accidental,” says Dr. Borgundvaag.
