NCT07024498

Brief Summary

The main purpose of this stepped wedge trial will be to test the impact of a bundle of implementation strategies designed to improve ED-outpatient care coordination on long-term buprenorphine retention among adult patients who start buprenorphine for opioid use disorder in a hospital emergency department (ED) and then are referred for continued outpatient buprenorphine treatment after they leave the ED. Our hypothesis is that adopting the bundle of implementation strategies will be associated with subsequent increases in: A) Cumulative number of days with active buprenorphine prescription at 3, 6, and 12 months after patients' initial ED visit (6 months = primary outcome) B) Proportion of patients with active buprenorphine prescriptions without gaps in buprenorphine coverage of more than 7 days at 3, 6, and 12 months after patients' initial ED visit C) Proportion of patients who fill at least 1 outpatient buprenorphine prescription within 30 days of their ED visit D) Clinician reported quality of ED-outpatient care coordination and care transitions

Outcome Measures

Primary Outcomes (1)

  • buprenorphine treatment (continuous)

    Cumulative number of days with active buprenorphine prescription after initial ED visit

    6 months

Secondary Outcomes (3)

  • buprenorphine treatment (continuous)

    3 months, 12 months

  • buprenorphine retention (binary)

    3 months, 6 months, 12 months

  • outpatient buprenorphine initiation

    30 days

Other Outcomes (2)

  • quality of care transitions

    approximately 3 months after the implementation period at each site, controlling for baseline values

  • quality of care coordination

    approximately 3 months after the implementation period at each site, controlling for baseline values

Study Arms (1)

Hospital ED and 2 associated outpatient clinics that provide buprenorphine treatment

OTHER

Each arm will receive the intervention at a different time point and will provide data for both the pre- and post-intervention conditions. During the pre-intervention periods, ED teams will use their existing workflows/procedures for referring patients to and coordinating with outpatient clinics that provide buprenorphine. During the post-implementation period, the ED and outpatient teams will use workflows/procedures that have incorporated the intervention.

Other: care coordination implementation strategies

Interventions

The intervention will be a bundle of implementation strategies developed during a prior study and informed by the multi-team systems framework. Core implementation strategies are expected to include a standardized ED substance use navigator note (with education and billing support), a mechanism for sharing PHI information across ED-clinic pairs that use different electronic health record systems, an improved ability for patients to directly contact EDs and clinics, ensuring ED and outpatient teams mutually understand each other roles, implementing procedures to increase capacity for same-day outpatient buprenorphine refills, and interactive problem solving with an external facilitation team. Strategies will be adapted to local contexts at each site.

Intervention Model
SEQUENTIAL
Model Details: This is a stepped wedge design with intervention assignment at the site level and the primary outcome assessed at the patient level. The intervention will be implemented sequentially at the site level. The sequence in which sites will implement the intervention was determined prospectively to alternate between sites that did versus did not participate in the prior study to identify implementation strategies. After a 9 month baseline period, one site will transition to the intervention condition every 3 months until all four have implemented the intervention. Patients will be followed for up to 12 months after their ED visit to assess buprenorphine treatment outcomes.

Data Sharing

IPD Sharing
Will share

De-identified IPD will be deposited in a public data registry as required by NIH HEAL data sharing guideilnes. However, due to state-level restrictions, individual level buprenorphine prescription data will not be shared.

Time Frame
expected 12 months after study completion
