Adaptive Interventions for Emergency Department Patients With Opioid Use Disorder

Trial design

Treatments tested in this trial

• SUN

  Behavioral BehavioralAn approach designed to change behavior, lifestyle, or mental health, such as counseling or psychotherapy.

  The SUN helps patients initiate buprenorphine treatment in the hospital, connects patients to follow-up care by facilitating appointments at outpatient clinics, addresses barriers to care, and serves as a resource for patients and clinicians. The SUN also advocates for a harm-reduction culture, models respectful interactions with people who use drugs and provides technical assistance to hospital staff to reduce stigma and discrimination.

• SUN + Telebridge

  Behavioral BehavioralAn approach designed to change behavior, lifestyle, or mental health, such as counseling or psychotherapy.

  TeleBridge consists of an immediate telehealth connection to a buprenorphine provider affiliated with the CA Bridge program who has expertise facilitating pharmacotherapy with individuals with OUD. TeleBridge addresses barriers to initiation of buprenorphine by reducing long wait times and the inability of the outpatient setting to initiate treatment on demand. TeleBridge also eliminates the need for patients to meet system-level requirements (e.g. on time for appointments during working hours while wearing appropriate attire) to obtain follow-up care. TeleBridge is a more resource-intensive form of care because it involves developing formalized relationships with outpatient providers and implementing telehealth protocols. TeleBridge is feasible based on the increased use of telehealth to expand post-ED care pathways.

• ED-ITT

  Behavioral BehavioralAn approach designed to change behavior, lifestyle, or mental health, such as counseling or psychotherapy.

  Enrolled patients who have not filled an outpatient buprenorphine (BUP) prescription at 30 days, return to the ED with an OUD-related event, or self-report nonadherence to the prescribed BUP are considered non-responders, and randomly assigned to a second stage intervention. For non-responders randomized to receive ongoing BUP treatment by an ED-based interim treatment team (ED-ITT), the SUN and Site PI (an ED physician with expertise in addiction medicine) will meet weekly to review the SUN's caseload, using a patient registry that has been modified for the trial. The registry: 1) prompts/documents proactive SUN outreach up to 3 additional months for non-responders, with an emphasis on prioritizing subsequent outreach to patients who have not yet engaged with outpatient care, or who are at risk of dropping out if the patient have transitioned; and 2) documents when the ED provider prescribes transitional BUP and when the patient would be due for a new prescription.

• ED-ITT + BHS

  Behavioral BehavioralAn approach designed to change behavior, lifestyle, or mental health, such as counseling or psychotherapy.

  Enrolled patients who have not filled an outpatient buprenorphine (BUP) prescription at 30 days, return to the ED with an OUD-related event, or self-report to the SUN nonadherence to the prescribed BUP will be considered non-responders, and randomly assigned to a second stage intervention. For non-responders randomized to receive ongoing BUP treatment from the ED-ITT+BHS, Behavioral Health Support (BHS) will be added to ED-ITT and include a weekly caseload review with an externally-affiliated psychiatrist with expertise in addiction medicine who will make mental health and substance use treatment recommendations, both pharmacological and behavioral, to the ED provider and SUN for up to 3 months. The consultant may also ask the SUN to do a more detailed behavioral health assessment, if insufficient information is available to make treatment recommendations. All prescriptions will be written by the ED provider.
