About the Overdose Data to Action project

Overdose Data to Action (OD2A) is a CDC cooperative agreement aimed at (1) expanding public health surveillance to allow for higher quality and more timely and comprehensive data collection for drug-related misuse and overdose morbidity and mortality, and (2) using these data to drive prevention strategies. The project has multiple surveillance and prevention focal points, including strengthening state and local capacity for public health programs; connecting health systems, state and local partners and agencies, and community members to improve prescribing practices and share data; increasing access and usability of the Prescription Drug Monitoring Program; improving treatment access and engagement; and building awareness among our community.

Common terms used in this dashboard:

  1. Substance use disorder (SUD): “occur[s] when the use of alcohol and/or drugs causes
    clinically significant impairment, including health problems, disability, and failure to
    meet major responsibilities at work, school, or home” 1
  2. Co-occurring disorders: disorders that a person experiences at the same time. In this
    dashboard, we present data on people with a substance use disorder who may also
    experience co-occurring mental illness, or vice versa (people with mental illness who
    may also experience co-occurring substance use disorder).
  3. Polysubstance use: use or consumption of more than one drug at the same time or
    within a short period of time of each other.
  4. Behavioral Health: emotional, psychological, and social aspects of health or well-being,
    including mental health and substance use.
  5. Crisis: “an acute emotional upset; it is manifested in an inability to cope emotionally,
    cognitively, or behaviorally and to solve problems as usual.” 2 Signs of a crisis may
    include feeling like something is wrong without being able to explain the reason for it,
    feeling hopeless, panicked, trapped, empty, or in a lot of pain, and nothing seems to help.

For Drug Overdose Surveillance & Epidemiology (DOSE)

Discharge Data Case Definitions:

Each category below includes unintentional, intentional self-harm (analyzed separately), and
undetermined intent poisonings for the initial encounter only–does not include assault, adverse
effect, or underdosing.

  1. All Drug: poisoning by drugs, medicaments and biological substances—does not include
    assault, adverse effect, underdosing; initial encounter only—does not include subsequent
    encounter(s) or sequela;
  2. All Opioids: poisoning by opium, heroin, other opioids, methadone, synthetic narcotics,
    fentanyl or fentanyl analogs, tramadol, synthetic narcotics, unspecified narcotics, and
    other narcotics
  3. Heroin: poisoning by heroin
  4. Stimulants: poisoning by cocaine, unspecified psychostimulants, caffeine,
    amphetamines, methylphenidate, ecstasy, and other psychostimulants
Important Data Considerations:
  • Missing Data: discharge data submitted by state/jurisdiction health departments can be
    delayed or temporarily stalled. Once data sharing resumes, emergency department visit or
    hospitalizations not shared during the initial data exchange, may not be backfilled or shared.
  • Data overlap: drug overdose visit counts are not mutually exclusive and represent the
    nesting of drug categories (i.e., suspected all drug category includes the number of suspected
    opioid-, heroin-, and stimulant-involved overdose visits; suspected heroin counts are included
    in the suspected opioid category; and cases that involve multiple substances can include both
    opioids and stimulants).
  • Reporting delays: as states/jurisdictions continue to onboard new data-sharing facilities to
    support syndromic surveillance activities, some facilities experience occasional interruptions
    in data availability. Data may also evolve over time (e.g., introducing new diagnosis codes).
    As a result, reported cases and rates can change over time.
  • Suspected overdoses/poisonings: these data are not necessarily verified by toxicological
    testing and are considered “suspected” overdoses, not confirmed cases.
  • Undercounts: data likely represent an undercount when accounting for inaccuracies in
