Oxycodone involvement in drug abuse deaths: a DAWN-based classification scheme applied to an oxycodone postmortem...

Area of Science:

• Forensic Toxicology
• Public Health
• Drug Abuse Epidemiology

Background:

• Oxycodone, particularly the OxyContin formulation, has been implicated in drug abuse fatalities.
• Accurate determination of the role of specific drugs in postmortem cases is crucial for public health.
• Existing data reporting systems may not fully capture the complexity of poly-drug abuse deaths.

Purpose of the Study:

• To establish a postmortem database of oxycodone-involved deaths.
• To evaluate the specific role of oxycodone and OxyContin in these fatalities.
• To categorize deaths based on drug abuse involvement and drug combinations using a standardized system.

Main Methods:

• Compiled a database of 1243 solicited postmortem cases from Medical Examiner and Coroner offices (1999-2002).
• Cases were included if death was opined to involve oxycodone; identification confirmed by toxicology and scene/witness evidence.
• Developed a categorization system based on the Drug Abuse Warning Network (DAWN) for drug abuse mortality.

Main Results:

• Of 1014 evaluated cases, 919 (90.6%) were drug abuse-related.
• Only 30 (3.3%) cases involved oxycodone as the sole reported chemical entity.
• The vast majority (889, 96.7%) of drug abuse cases involved multiple drugs, commonly combined with benzodiazepines, alcohol, cocaine, or other narcotics.

Conclusions:

• Oxycodone is frequently involved in drug abuse fatalities, but rarely as the sole contributing substance.
• Multiple drug abuse is a significant factor in oxycodone-related deaths, complicating cause of death attribution.
• A standardized system for reporting opioid mortality, acknowledging poly-drug involvement, is recommended for future studies.
