Pharmaceutical opioid use and dependence among people living with chronic pain: associations observed within the Pain and Opioids in Treatment (POINT) Cohort
Design: Baseline data were obtained from a national sample of 1,424 people across Australia (median 58 years, 55% female and experiencing pain for a median of 10 years), who had been prescribed opioids for CNCP. Current opioid consumption was estimated in oral morphine equivalent (OME; mg per day), and ICD-10 pharmaceutical opioid dependence was assessed using the Composite International Diagnostic Interview.
Results: Current opioid consumption varied widely: 8.8% were taking <20 mg OME per day, 52.1% were taking 21-90 mg OME, 24.3% were taking 91-199 mg OME, and 14.8% were taking >= 200 mg OME. Greater daily OME consumption was associated with higher odds of multiple physical and mental health issues, aberrant opioid use, problems associated with opioid medication and opioid dependence. A significant minority, 8.5%, met criteria for lifetime ICD-10 pharmaceutical opioid dependence and 4.7% met criteria for past year ICD-10 pharmaceutical opioid dependence. Multivariate analysis found past-year dependence was independently associated with being younger, exhibiting more aberrant behaviors and having a history of benzodiazepine dependence.
Conclusions: In this population of people taking opioids for CNCP, consumption of higher doses was associated with increased risk of problematic behaviors, and was more likely among people with a complex profile of physical and mental health problems.
