New analysis looks at who is receiving high-strength opioids in Ontario
Toronto, August 2, 2016
By Leslie Shepherd
Nine out of 10 people in Ontario who receive government reimbursement for their prescription high-strength opioid tablets or patches are not palliative care patients, a new analysis has found.
The Ontario Drug Policy Research Network undertook the analysis after concerns were raised about the impact on palliative care patients of the Ontario government’s recent announcement that it would stop paying for high strength opioids.
Tara Gomes, the network’s co-principal investigator, said this analysis was conducted to provide evidence to inform all parties involved in the conversation.
The network, based at St. Michael’s Hospital, examined prescriptions for three long-acting opioids – morphine, fentanyl and hydromorphone – that were reimbursed by the Ontario Drug Benefits program between April 1, 2014, and March 31, 2015. That data is housed at the Institute for Clinical Evaluative Sciences (ICES).
The analysis found more than 42 million long-acting opioid tablets or patches were prescribed during that time and reimbursed by the government. Of those, almost 11 per cent were high strength – the ones the Ontario government plans to stop funding, or “de-list” in January 2017.
The analysis also found that government-funded long-acting opioid tablets and patches were prescribed to 87,453 people in the year studied. Of those, almost 16 per cent had received at least one prescription for a high-strength opioid, or 13,695 people. Only 10 per cent of those high-strength opioid users had received palliative care in the previous six months.
The study also looked at this issue from the perspective of the broader population of 62,602 people receiving palliative care in the province over the study period. In this population, 42.5 per cent (26,620 people) were treated with opioids that were reimbursed by the Ontario Drug Benefits program, but only 2.7 per cent (1,673 people) received high-strength opioids.

Gomes said while the number of palliative care patients affected was small compared to the total number of palliative care patients in the province, the analysis still identifies a number of individuals who could be impacted by the government’s changes.
“I suggest that the focus now shift to determining how to ensure that there is a smooth, safe transition for patients once these products are delisted. That should include ensuring access to addiction services for those seeking treatment, appropriate tapering of opioid doses by physicians, and determining whether any exemptions to the policy should be made for palliative care physicians.”
Gomes noted that new guidelines from the Centers for Disease Control and Prevention in the United States recommend that physicians avoid prescribing opioids at daily doses above 90 milligrams of morphine or equivalent for chronic pain because of evidence suggesting that the harms likely outweigh the benefits in this population. All of the high strength formulations included in Ontario’s policy exceed this threshold.
