Amidst the ongoing opioid crisis, the number of individuals with opioid use disorder is on the rise.
Opioid use disorder, a chronic, life-limiting illness, leads to substantial impairment and distress.
As the population with opioid use disorder ages, there is a growing need for access to palliative care at the end of their lives.
A study led by Dr. Jenny Lau, Medical Director of the Harold and Shirley Lederman Palliative Care Centre at Princess Margaret Cancer Centre, delves into the characteristics of people with opioid use disorder at the end of their lives and investigates the accessibility of palliative care for this demographic.
The research, based on a comprehensive study including information from
ICES on 679,840 deaths, revealed that 11,200 of the deceased, or 1.6 per cent, had opioid use disorder.
Individuals with opioid use disorder died at younger ages than those without the disorder – 50 versus 78 – and were more likely to reside in marginalized neighbourhoods.
Comparatively, individuals with opioid use disorder were 16 per cent less likely to receive palliative care than those without the disorder, particularly in clinics and at home.
This disparity is most likely linked to the high number of individuals with opioid use disorder who die suddenly from drug poisoning and do not have an opportunity to receive palliative care.
The most common reasons why physicians provided palliative care for individuals with opioid use disorder were cancer, liver cirrhosis and sepsis.
"The majority of conversations about the opioid crisis focus on the high number of opioid toxicity deaths," says Dr. Lau, lead author of this study, who is also
a member of the Global Institute of Psychosocial, Palliative and End-of-Life Care Operations Committee. "The unfortunate reality is that people with opioid use disorder are dying young from other causes as well.
"If we can improve our understanding of this population and the health care that they receive at the end of their lives, we can identify opportunities to intervene and improve their quality of life."
This research underscores the urgency of addressing the disparities in palliative care provision for individuals with opioid use disorder. By understanding these discrepancies, researchers can pave the way for targeted interventions to ensure equitable end-of-life care for all.
With the proper training in both palliative care and addiction medicine and attention to socioeconomic inequalities, health care providers can significantly improve the quality of life for patients with opioid use disorder in their final days.
