About
Post-surgical opioid prescribing intended for the short-term management of acute pain may lead to long-term opioid use, and its associated harms. This study was undertaken to determine the prevalence of prolonged post-surgical opioid use, and patient-related factors associated with prolonged post-surgical opioid use.
Full description
There are growing concerns that surgery is a risk factor for chronic opioid use. Existing studies suggest that post-surgical opioid prescribing intended for the short-term management of acute pain may result in unintended long-term opioid use for a small, but meaningful number of patients.
Increasing numbers of patients are discharged from hospital post-surgery with opioids for the management of their acute post-surgical pain. Opioids have proven efficacy for the management of acute post-surgical pain, but can cause significant harm when used long-term for non-cancer pain. Evidence suggests that post-surgical opioid use continues in some patients for years after surgery.
Identification of patients at risk of prolonged opioid use after surgery may assist in reducing the adverse outcomes associated with long-term opioid use. Pre-operative risk stratification tools may be of use in identifying surgical patients at risk of long-term opioid use. Validated tools are widely used to identify patients at high risk of opioid misuse in the chronic pain setting, but currently there is no optimal method to predict patients at risk of chronic opioid use after surgery.
Existing studies have found that a wide range of patient characteristics and psychiatric comorbidities are associated with long-term opioid use in a post-surgical setting.
There are 5 primary study procedures in the investigators research project:
The investigators primary study objective is to determine the prevalence of prolonged post-surgical opioid use, defined by our study as patients taking opioids >90 days post-surgery. The investigators secondary objective is to identify patient-related factors that are independently associated with prolonged post-surgical opioid use. These factors may be used to develop a pre-operative screening tool for patients undergoing surgery, in order to assign a level of risk for chronic post-surgical opioid use.
