          Abstract

          North America is experiencing an unprecedented overdose crisis driven by the proliferation of fentanyl and its analogues in the illicit drug supply. In 2018 there were 67,367 drug overdose deaths in the United States, and since 2016, there have been more than 14,700 overdose deaths in Canada, with most related to fentanyl. Despite concerted efforts and some positive progress, current public health, substance use treatment, and harm reduction interventions (such as widespread naloxone distribution and implementation of supervised consumption sites) have not been able to rapidly decrease overdose fatalities. In view of the persistent gaps in services and the limitations of available options, immediate scale-up of low-barrier opioid distribution programs are urgently needed. This includes “off-label” prescription of pharmaceutical grade opioids (e.g., hydromorphone) to disrupt the toxic drug supply and make safer opioids widely available to people at high risk of fatal overdose.

              Modelling the combined impact of interventions in averting deaths during a synthetic‐opioid overdose epidemic

              The province of British Columbia (BC), Canada has experienced a rapid increase in illicit drug overdoses and deaths during the last four years, with a provincial emergency declared in April 2016. These deaths have been driven primarily by the introduction of synthetic opioids into the illicit opioid supply. This study aimed to measure the combined impact of large-scale opioid overdose interventions implemented in BC between April 2016 and December 2017 on the number of deaths averted. We expanded on the mathematical modelling methodology of our previous study to construct a Bayesian hierarchical latent Markov process model to estimate monthly overdose and overdose-death risk, along with the impact of interventions. Overdose events and overdose-related deaths in BC from January 2012 to December 2017. The interventions considered were take-home naloxone kits, overdose prevention/supervised consumption sites and opioid agonist therapy Counterfactual simulations were performed with the fitted model to estimate the number of death events averted for each intervention, and in combination. Between April 2016 and December 2017, BC observed 2177 overdose deaths (77% fentanyl-detected). During the same period, an estimated 3 030 (2 900 – 3 240) death events were averted by all interventions combined. In isolation, 1 580 (1 480 – 1 740) were averted by take-home naloxone, 230 (160 – 350) by overdose prevention services, and 590 (510 – 720) were averted by opioid agonist therapy. A combined intervention approach has been effective in averting overdose deaths during British Columbia’s opioid overdose crisis in the period since declaration of a public health emergency (April 2016 to December 2017). However, the absolute numbers of overdose deaths have not changed.
