Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The ADAPT-ED study is a two-stage, sequential multiple assignment randomized trial (SMART) to inform the development of an adaptive intervention that is optimally effective in increasing long-term buprenorphine use for adults presenting to the ED with probable opioid use disorder (OUD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The ADAPT-ED study is a two-stage, sequential multiple assignment randomized trial (SMART) to inform the development of an adaptive intervention that is optimally effective in increasing long-term buprenorphine use for adults presenting to the ED with probable OUD. The trial includes (1) two first stage components: the CA Bridge Model with Substance Use Navigator assisted treatment initiation and linkage to care (SUN) or CA Bridge plus immediate telehealth connection to an outpatient provider (SUN+TeleBridge); (2) a dynamic tailoring variable describing (non) response to the first stage: whether the patient has not filled an outpatient buprenorphine prescription at 30 days or whether the patient returns to the ED with an OUD-related event or self-reports non-adherence to buprenorphine within the first 90 days; (3) two second-stage components for non-responders; either ongoing buprenorphine treatment by an ED-based interim treatment team (ED-ITT) or ED-ITT augmented with behavioral health support (ED-ITT+BHS). First-stage responders will receive no further active intervention unless the participant returns to the ED or notifies the SUN about no longer taking buprenorphine within 90 days of study enrollment.

Hypothesis 1: The investigators hypothesize that the most intensive Adaptive Treatment Strategy (ATS) will lead to (a) more days of buprenorphine use and (b) a longer time to overdose, self-harm, or death compared to the least intensive ATS.

Hypothesis 2: The investigators hypothesize that (a) SUN+TeleBridge in the first stage of the ATS and (b) ED-ITT+BHS in the second stage of the ATS will each lead to more days of buprenorphine use and a longer time to overdose, self-harm, or death within the first 12 months compared to SUN and ED-ITT, respectively, and (c) there is a synergistic positive effect of receiving both SUN+TeleBridge and ED-ITT+BHS on days of buprenorphine use.

Hypothesis 3: The investigators hypothesize that the effect of SUN+TeleBridge versus SUN and the effect of ED-ITT+BHS versus ED-ITT among first stage non-responders will be larger among those with (a) a history of overdose at baseline and (b) co-occurring depression or PTSD at baseline relative to those who do not have either or those conditions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SUN + Telebridge followed by ED-ITT + BHS

In Arm F, participants are randomized to receive SUN-assisted treatment initiation and linkage to care plus SUN-assisted immediate telehealth connection to an outpatient provider. The patients are determined to be non-responders within 90 days and are subsequently randomized into the ED-ITT + BHS condition to receive ongoing buprenorphine treatment by an ED-based interim treatment team augmented with a behavioral health consultant who will provide behavioral health support for up to 3 months.

Group Type ACTIVE_COMPARATOR

SUN + Telebridge

Intervention Type BEHAVIORAL

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 + BHS

Intervention Type BEHAVIORAL

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.

SUN with no follow up

In Arm A, participants are randomized to receive SUN-assisted treatment initiation and linkage to care. The patients are determined to be responders by 90 days and therefore receive no active follow up.

Group Type ACTIVE_COMPARATOR

SUN

Intervention Type BEHAVIORAL

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 followed by ED-ITT

In Arm B, participants are randomized to receive SUN-assisted treatment initiation and linkage to care. The patients are determined to be non-responders within 90 days and are subsequently randomized into the ED-ITT condition to receive ongoing buprenorphine treatment by an ED-based interim treatment team.

ED-ITT

Intervention Type BEHAVIORAL

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.

SUN followed by ED-ITT + BHS

In Arm C, participants are randomized to receive SUN-assisted treatment initiation and linkage to care. The patients are determined to be non-responders within 90 days and are subsequently randomized into the ED-ITT + BHS condition to receive ongoing buprenorphine treatment by an ED-based interim treatment team augmented with a behavioral health consultant who will provide behavioral health support for up to 3 months.
