California Bridge Program

This statewide program in California provides access to medications for opioid use disorder in the emergency departments of 53 hospitals and links to treatment

Recognizing that the emergency department is a potential vital touchpoint for initiating evidence-based interventions for opioid use disorder (OUD), the California Bridge Program is a partnership with the California Poison Control System and the California Hub and Spoke System to provide 24-7 emergency access to initiation of buprenorphine treatment for OUD in all California communities. 

The program is built on three pillars

  • Treatment: Medications for opioid use disorder (e.g. buprenorphine) are accessible in the emergency department and in all other hospital departments.  Treatment is provided rapidly in response to patient needs, not contingent on laboratory screening results, insurance status, commitment to treatment, or abstinence from all substances. Providers use a harm reduction approach and put patient needs at the center of the path to treatment
  • Culture: Hospital culture is welcoming and does not stigmatize substance use, making disclosure of substance use inviting. There is a focus on using destigmatizing language.
  • Connection: Linkage to ongoing care involves active support and follow up with patients. There is an arrangement with at least one community provider to accept referrals within 72 hours after buprenorphine is initiated in the emergency department. 

More information on the program can be found in this presentation and this guide

Publications addressing initiation of buprenorphine in the emergency department can be found at this link. The program also offers a website that guides clinicians on how to implement a bridge clinic, including clinical protocols, best practices, and toolkits. 

The emergency department could be a vital touchpoint to initiate evidence-based treatment for opioid use disorder.

Evidence of Program Effectiveness

There are no formal evaluations of the California Bridge program, but the general model and related models are evaluated in the peer reviewed literature

"Most patients received hospital-administered buprenorphine (58 %) and/or a buprenorphine prescription (55 %); 26 % received neither treatment. Patients with unstable housing had greater odds of hospital-administered buprenorphine compared to patients with stable housing. Patients with Medicaid had greater odds of receiving a buprenorphine prescription compared to patients with other insurance. Co-methamphetamine use was not associated with outcomes...Patients with OUD are successful in accessing same-day MOUD in CA Bridge hospital settings over a significant period. Importantly, access to MOUD in these settings was facilitated for patients traditionally not treated using buprenorphine, i.e., those with housing instability, Medicaid insurance, and co-methamphetamine use. Findings suggest barriers to MOUD for patients with social and economic disadvantages can be lowered by changing treatment delivery." (Kalmin et al., 2021)
