• Description:
  Background and Aims:
  
  Tracking specific drugs contributing to drug overdose deaths is limited when relying on death certificate (DC) data alone. This study aimed to determine whether integrating DC data with medical examiner/coroner reports, including postmortem toxicology and death investigation findings, would enhance identification of (1) heroin and pharmaceutical morphine involvement in overdose deaths and (2) fentanyl source (illicitly manufactured versus pharmaceutical).
  
  Design:
  
  Retrospective analysis of heroin, pharmaceutical morphine, illicitly manufactured fentanyl (IMF) and pharmaceutical fentanyl involvement in fatal overdoses. DC and toxicology data were compared with enhanced definitions integrating overdose scene, witness and toxicology evidence.
  
  Setting:
  
  United States: 38 states and the District of Columbia, participating in Centers for Disease Control and Prevention (CDC)-funded opioid overdose death surveillance.
  
  Cases:
  
  Opioid overdose decedents from funded jurisdictions; deaths during 1 January 2018–31 December 2019.
  
  Measurements:
  
  Using medical examiner/coroner report data, deaths with 6-acetylmorphine and/or morphine detected by postmortem toxicology were defined as confirmed, probable or suspected heroin deaths, or probable pharmaceutical morphine deaths. Fentanyl was defined as probable or suspected IMF or probable pharmaceutical fentanyl.
  
  Findings:
  
  The enhanced definition defined 18 393 deaths as confirmed, probable, or suspected heroin deaths (including 2678 with morphine listed as cause of death on the DC) and 404 as probable pharmaceutical morphine deaths. Among deaths with fentanyl detected, 89.3% were defined as probable or suspected IMF and 1.0% as probable pharmaceutical fentanyl. Fentanyl source could not be determined for 9.7% of deaths.
  
  Conclusions:
  
  Integrating drug overdose scene, witness and toxicology findings can improve identification of specific drugs contributing to overdose deaths and enhance overdose intervention targeting.
