Emulating target trials to strengthen the evidence base for the clinical management of opioid use disorder

In 2016, following a dramatic increase in opioid-related overdose deaths, the province of British Columbia (B.C.), Canada declared a public health emergency. Opioid agonist treatment (OAT) is among the most effective tools available to combat the epidemic. However, OAT uptake and retention is sub-optimal in B.C. and internationally, compromised largely by social and structural factors, but also deviations from evidence-based standards of care and fragmented care, particularly for those with concurrent disorders. Furthermore, a number of aspects of Canadian and U.S. clinical guidelines for the management of opioid use disorder are based on limited and low-quality evidence. This proposal aims to apply cutting-edge methods for causal inference in emulating a series of ‘target trials’ using B.C.’s extensive population-based linked administrative databases. The target trial framework channels counterfactual theory in providing a flexible basis for comparing the effects of treatment and clinical management strategies on either an intent-to-treat or per-protocol basis.

Learning Objectives:

  • Overview of treatment options and clinical management of opioid use disorder in B.C.
  • Application and use of B.C.’s linked administrative databases for research
  • Description of current statistical methods for causal inference with observational data
