SUDORS is part of the CDC's Enhanced State Opioid Overdose Surveillance program. It collects data on all drug overdose deaths in 47 states and the District of Columbia. Data sources for this can include death certificates and medical examiner/coroner reports (including scene findings, autopsy reports, and full postmortem toxicology findings).
The goals of SUDORS is to better understand overdose circumstances, improve data timeliness and accuracy, and identify specific substances causing or contributing to overdoses.
Multiple methods are used to identify drug overdose deaths. SUDORS can identify emerging drugs, include data on drugs that caused death as well as additional drugs detected, and provide data on circumstances and scene evidence that provide the context surrounding an overdose death.
