Opioid-Related Overdose Fatality Cases in Two Florida Counties

Area of Science:

• Forensic Toxicology
• Public Health
• Epidemiology

Background:

• Drug-related deaths pose a significant public health challenge.
• Understanding geographical and temporal trends in overdose mortality is crucial for targeted interventions.

Purpose of the Study:

• To analyze trends in drug-related deaths in Pasco and Pinellas Counties, Florida (2011-2016).
• To investigate the specific role of fentanyl in overdose deaths.
• To compare drug mortality patterns in rural versus suburban populations.

Main Methods:

• Utilized data from Medical Examiner's Offices for calendar years 2011-2016.
• Employed nonparametric ANOVA for yearly comparisons.
• Conducted binary logistic regression to identify co-occurring drugs with fentanyl.

Main Results:

• No significant differences in month or day of week for drug fatalities.
• Higher incidence of drug-related mortalities during daylight hours.
• Pinellas County had more fentanyl-related mortalities than Pasco County.
• Fentanyl and heroin frequently co-occurred; other opioids and ethanol showed negative association with fentanyl.

Conclusions:

• Drug overdose characteristics vary geographically.
• Fentanyl plays a significant role in overdose mortality, often with heroin.
• Findings can inform targeted public health interventions for drug abuse and overdose prevention.
