Here's How We're Making a Difference

Advancing Innovative Opioid Prevention Partnerships to Save Lives

The opioid epidemic is having a devastating impact in communities across the nation, fueling a dramatic increase in premature deaths. In California, there were almost 2,000 opioid overdose deaths in 2016. In late 2015, the California Health Care Foundation (CHCF) launched a statewide network of 16 local coalitions in 23 counties focused on three priority strategies—safe opioid prescribing, use of medication-assisted addiction treatment (MAT), and access to naloxone to reverse drug overdoses. 

In 2017, PHI conducted an assessment of the California Health Care Foundation’s network of opioid safety coalitions to identify what strategies are working at the local level. PHI found that more than 90% of coalitions facilitated adoption of safer prescribing guidelines, more than 75% increased access to naloxone to reverse overdoses, and more than 50% expanded use of medication-assisted addiction treatment.
