Overdose prevention
starts with data
Overdose Measures Matter offers a set of recommended indicators to help communities collect and use data for overdose prevention
These indicators are designed to help communities evaluate the impact of their programs, advance health in every community, particularly underserved communities and those at the highest risk and address the structural and underlying barriers to overdose related health outcomes for everyone. With these indicators, organizations can work to:
Encourage partners to collaborate, collect and use data
Tailor overdose prevention interventions
Measure progress toward fair and just outcomes
Overdose Measures Matter is intended for data collection on all substances, not just opioids.
What are indicators?
Indicators are tools that help us measure progress. Indicator data can be numbers, such as counts or percents, or descriptions that help us understand the progress of a project or program.
You can use indicators to assess or understand issues, events or change and to determine whether a program is achieving its goals. Learn more about numerical (quantitative) and descriptive (qualitative) indicators.

Indicators, and the measures associated with them, not only provide insights about what or how much of something is happening, but also for whom and under what conditions.

The indicators are organized in the following categories:
- HARM REDUCTION
- HEALTH ACCESS
- STIGMA REDUCTION
- LINKAGE TO CARE
- PARTNERSHIPS
- PEER WORKFORCE SUPPORT
Learn more about the indicator categories.
These indicators were developed based on feedback from diverse groups, ensuring they would be practical for people implementing overdose prevention and services. To explore additional indicators compiled by other experts, visit the Resources section.
