National overdose trends indicate the need for a comprehensive, public health approach that encompasses primary prevention of substance use, overdose and mortality prevention, monitoring and surveillance, and access to treatment, recovery and harm reduction services. ASTHO provides capacity building and technical assistance for state and territorial health agencies in these areas to build strong public health leadership for substance use prevention and surveillance, establish effective multidisciplinary partnerships, and support the implementation of policies that are informed by evidence.

Overdose Data to Action (OD2A)

ASTHO is a technical assistance and capacity building partner for CDC’s Overdose Data to Action (OD2A) cooperative agreement to address the opioid overdose epidemic. ASTHO supports OD2A recipients’ opioid overdose prevention and surveillance efforts, including initiatives around:

  • overdose morbidity and mortality data
  • innovative surveillance strategies
  • prescription drug monitoring programs (PDMP)
  • state and local integration
  • linkage to care
  • provider and health systems support
  • public health/public safety partnership
  • other innovative prevention strategies

Opioid Preparedness

ASTHO works closely with CDC’s Opioid Rapid Response Program to enhance state capacity to respond to opioid-related emergencies, including overdose spikes and disruptions in access to opioid prescriptions. ASTHO assists members by conducting opioid preparedness exercises with state health agencies and their partners and developing resources based on identified jurisdictional needs.

Overdose Mortality Data Improvement

ASTHO works with medicolegal death investigators, such as medical examiners and coroners (ME/Cs), to support effective investigations of overdose deaths. ASTHO recognizes that ME/Cs are integral to overdose monitoring and surveillance efforts, as well as public health mortality surveillance more broadly, and seeks to support these systems as part of the broader public health workforce. Key initiatives include efforts to improve drug specificity on death certificates, address the national shortage of forensic pathologists, and the Project ECHO on Overdose Fatality Investigation Techniques.
