Predictors of persistent prescription opioid analgesic use among people without cancer in Australia.

ABSTRACT:

Aims

To identify patterns of opioid analgesic use and determine predictors of persistent opioid use among people without cancer.

Methods

A population-based cohort study of Australians initiating prescription opioids from July 2013 to December 2015 was conducted using data from a random 10% sample of people who accessed medicines through Australia's Pharmaceutical Benefits Scheme. A 12-month retrospective period was used to define opioid initiation, exclude people with cancer and determine comorbidities. Persistent use over 12 months since initiation was identified through group-based trajectory modelling. Odds ratios (OR) and 95% confidence intervals (CIs) for predictors of opioid persistence were estimated using logistic regression.

Results

The cohort consisted of 43
