Evidence of Pre-mortem Opioid Use among Fentanyl Overdose Decedents in a Safety Net Healthcare System

Abstract

The rapid increase in fentanyl overdose deaths, particularly those also attributed to stimulants, has led to concerns about unintentional fentanyl exposure. Utilizing vital and medical record data, we identified overdose decedents from 2018 to 2021 in San Francisco who received care in the safety net system in the 3 years preceding death. Among 506 decedents, medical record evidence of pre-mortem opioid use was present for 48% of stimulant-only, 56% of stimulant-fentanyl, 65% of fentanyl-only, and 82% of non-fentanyl opioid decedents (p<0.001). Among stimulant-fentanyl decedents, an increase in 10 years of age (adjusted odds ratio (aOR) 0.74 [95% CI:0.59-0.94]) and race other than White or Black (aOR 0.36 [95% CI:0.15-0.87]) had lower odds of evidence of pre-mortem opioid use. While not conclusive, these findings raise the possibility that a significant proportion of fentanyl overdose decedents in San Francisco may have not intended to consume an opioid on the occasion of their death.
