Characteristics of fatal opioid overdoses with stimulant involvement in Tennessee: A descriptive study using 2018 State Unintentional Drug Overdose Reporting System Data

PURPOSE

Opioid overdose deaths involving stimulants are on the rise. Demographic characteristics for these deaths to be used in prevention efforts have not been established.

METHODS

We conducted a statewide retrospective study to evaluate the characteristics of fatal opioid overdoses with stimulant involvement using 2018 Tennessee State Unintentional Drug Overdose Reporting System data. Data sources included death certificates, autopsy reports, toxicology, and prescription drug monitoring program data. Frequencies were generated to compare demographics, circumstances, opioid history, death scene information, bystander intervention, and toxicology between fatal opioid overdoses with and without stimulant involvement.

RESULTS

A total of 1183 SUDORS opioid overdose deaths occurred in Tennessee in 2018 of which 434 (36.7%) involved a stimulant. Fatal opioid overdoses involving stimulants had higher frequencies of illicit drugs on toxicology specifically marijuana, fentanyl, and heroin compared to fatal opioid overdoses without stimulants. Fatal opioid overdoses involving stimulants had higher frequencies of scene indications of injection drug use compared to fatal opioid overdoses without stimulant involvement.

CONCLUSIONS

Fatal overdoses are shifting from mainly opioid to multidrug involvement and over one-third include use of stimulants. This analysis can help public health practitioners understand the circumstances around fatal opioid overdoses involving stimulants to inform tailored prevention strategies.
