California's Surveillance Activities

Opioid-related overdose data from various sources allows us to have a more complete understanding of the current issues surrounding the opioid crisis, and helps to inform policy and best practices across the state.


Data Gathering and Sharing Task Force

The California Department of Public Health (CDPH) facilitates the Statewide Opioid Safety Workgroup's Data Gathering and Sharing Task Force that serves as an advisory body on opioid related data topics. The focus of the Task Force is to promote and increase access and sharing of high-quality data on opioid use and misuse for the purpose of reducing opioid overdoses and deaths throughout California. Task force members include representatives from state and local agencies including epidemiologists and researchers.


California Opioid Overdose Surveillance Dashboard

Opioid%20deaths%20graphTo support and improve data sharing and integration, CDPH developed and maintains the California Opioid Overdose Surveillance Dashboard. The dashboard serves as the primary data dissemination  tool for opioid-related and other drug overdose data that incorporates statewide and geographically-specific opioid overdose and prescription data and displays them in enhanced visualizations. Data available on the dashboard includes:

  • Mortality data from CDPH Center for Health Statistics and Informatics
  • Prescription dispensing data from the Department of Justice's CURES 2.0, California's Prescription Drug Monitoring Program
  • Emergency department visit and inpatient discharge data from the Office of Statewide Health Planning and Development


Statewide Unintentional Drug Overdose Reporting System

Through funds from the Centers for Disease Control and Prevention (CDC) CDPH has implemented the enhanced surveillance program, State Unintentional Drug Overdose Reporting System (SUDORS), which compiles information from existing data sources on drug overdose deaths. SUDORS combines data from various sources including vital records, coroners/medical examiners, and toxicology results to further understand the circumstances surrounding overdose deaths in California.

Data on opioid and other drug use among California residents is collected in population-based statewide surveys, which can be viewed below:
