Research objective: 

The goal of the project is to better characterize and validate the pathway between injury among both men and women and illicit drug overdose.

Research Questions:
Broadly, this project aims to describe the trajectory from injury to overdose.
These are the specific questions that the model will be able to answer:
1. What is the overdose (OD) risk of an injured person who received a prescription for opioids following an injury seen in the emergency deparment (ED)?
2. What is the risk of a person who was injured at work to receive a prescription for opioids following an injury seen in the ED?
3. Does receiving a prescription for opioids affect the risk of an eventual overdose among injured workers who are managed by WorkSafeBC?
4. Does having a previous prescription for opioids have an impact on the pathway?
5. How is overdose risk affected by prescription of an opioid and opioid agonist therapy (OAT) prescription?

Hypotheses:
1. Having an opioid prescription increases OD risk.
2. Opioid prescriptions are more common in those sustaining work-related injuries compared to non-work-related injuries.
3. It is not expected that OD risk is higher among injured workers who are managed by WorkSafe BC compared to the general population.
4. Previous prescription of opioids increases OD risk.
5. OAT prescription reduces OD risk.
