Bolstering What Works to Stem the Opioid Crisis

In 2019, PHI's California Bridge launched an accelerator training program at 52 hospitals and ERs across the state, supporting healthcare providers offering 24/7 access to medication for addiction treatment (MAT). Since the program’s inception in April 2019, these sites have collectively served just under 5,000 people, 1856 of whom have been successfully connected with an ongoing source of outpatient substance use treatment. 

PHI’s California Opioid Safety Network (COSN) is the largest opioid safety network in the country, serving 85% of California's 30 million people. Now, 90% of COSN coalitions are distributing naloxone and 91% are increasing access to MAT.

And in June, PHI hosted U.S. Surgeon General Jerome Adams at its first-ever National Opioid Leadership Summit, bringing together public health, health care and criminal justice experts to share the best practices and develop cross-sector solutions.
