About The State Unintentional Drug Overdose Reporting System (SUDORS)

The State Unintentional Drug Overdose Reporting System (SUDORS) is a component of the Overdose Data to Action (OD2A) project.

SUDORS collects and links data on all unintentional and undetermined opioid-related overdose deaths occurring in Massachusetts. The system combines information from death certificates, medical examiner records and toxicology reports. The purpose of the data is to provide a more complete understanding of when, where, and how drug overdose deaths occur, as well as other circumstances related to these events.

The OD2A project is a national initiative funded by the Centers for Disease Control and Prevention (CDC) that started in September 2019. Massachusetts was one of the first 12 states funded for this work via previous initiatives of the CDC which including the Enhanced State Opioid Overdose Surveillance (ESOOS) project. More information on OD2A is available at www.cdc.gov/drugoverdose/od2a/index.html.


The goals of OD2A are:

  • Quicker reporting of nonfatal and fatal opioid overdoses and risk factors linked to fatal overdoses
  • Sharing data with key stakeholders working to prevent opioid-involved overdoses
  • Sharing data with CDC to support improved multi-state surveillance of and response to opioid-involved overdoses
