Evaluation of the gap in delivery of opioid agonist therapy among individuals with opioid-related health problems: A population-based retrospective cohort study

Model results indicated that males had higher odds of being on OAT each month but lower odds of OAT retention, while the reverse was observed for older individuals and individuals with higher neighbourhood income. Individuals residing in rural areas and with a history of mental health diagnoses had poorer outcomes overall, including lower odds of being on OAT each month and OAT retention, as well as higher risk of starting/stopping OAT. Individuals with a history of mental health diagnoses also had a higher risk of death, regardless of OAT status.
