We modelled the outcome using a Poisson multivariable regression and reported relative risks with 95% confidence intervals.<\/p>\n<p><strong>Results<\/strong> \u2014 We identified 3468 individuals with non-traumatic spinal cord dysfunction (50.35% male) with 66.58% who were aged \u226566. Over half of the cohort (59.46%) received opioids during the observation period. Being female, previous opioid use before rehabilitation, increasing comorbidity level, low functional status, and having a previous diagnosis of osteoarthritis were significant risk factors for receiving opioids after discharge, as shown in an adjusted multivariable analysis. Increasing length of rehabilitation stay was protective against opioid receipt after discharge. Risk of receiving opioids varied with age. Younger individuals had a significantly higher risk of future opioid use, a risk that peaked around 30\u201340 years of age (aRR 1.54, 95% CI 1.42\u20131.67 for age 40, as compared to age 80). Risk of opioid use following discharge decreased as age increased beyond 40 years, as compared to age 80.<\/p>\n<p><strong>Conclusions<\/strong> \u2014 Many individuals with non-traumatic spinal cord dysfunction in Ontario are prescribed opioids after discharge from inpatient rehabilitation. This may be problematic due to the number of severe complications that may arise from opioid use and their use in this population warrants future research.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Study design \u2014 Cohort study.
