Prescription Opioid Use and Safety
Bind to opioid receptors in the central nervous system
Therapeutic Use Analgesia
Side Effects Respiratory depression Dependence
Causes of Prescription Opioid Death
Nonmedical use? Obtaining from nonprescription sources Using more than prescribed
Increase in opioids prescribed? Inherent risks of drugs Unsafe prescribing practices
Risk factors inadequately understood Lack of knowledge about decedents Lack of control group who used opioids
Study Objective and Design
Identify risk factors for death
People who died from prescription opioids
People who used prescription opioids
Compared populations
Data Sources: Decedents
Medical examiner records
Death certificates
Next-of-kin interviews
Decedents (N = 254)
October 26, 2008–October 25, 2009 Prescription opioid cause of death Accidental or intent-undetermined manner
of death Utah residents ≥18 years of age Interview completed by next-of-kin
Data Source: Comparison Group
Behavioral Risk Factor Surveillance System (BRFSS)
Self-reported
Landline only
Non-institutionalized
Weighted to reflect state population
Prescription pain medication questions added 2008
Comparison Group (N = 1,308)

Confounding variables
Conclusion
Risk of death complicated
Use outside prescription bounds risky
Decedents needed chronic pain therapy
Other factors important
Providers can recognize risk and control exposure
Recommendations
Prescribers should screen chronic pain patients
Update screening tools to include risk factors
Continue research on risk factors Smoking Illicit substance use Mental illness
