The Emergency Department Longitudinal Integrated Care

Not Applicable

Recruiting

• Conditions: Opioid Use Disorder
• Interventions: Other: ED-LINC

• Registration Number: NCT05327166
• Lead Sponsor: University of Washington

Brief Summary

Collaborative care is a comprehensive patient-centered model of healthcare delivery targeting behavioral health or substance use that stems from the chronic disease management framework. The intervention being tested ('Emergency Department Longitudinal Integrated Care' or ED LINC) derives from the collaborative care model and has demonstrated feasibility in previous studies.

This study expands on the model to test the effectiveness of the ED-LINC intervention when compared with usual care. The study team primarily hypothesizes that patients randomized to the ED-LINC intervention, when compared to patients randomized to usual care, will demonstrate: 1) significant reductions in self-report illicit opioid use, 2) significant increases in initiation and retention of medications for opioid use disorder, and 3) significant reductions in ED utilization.

Detailed Description

This is a randomized clinical trial designed to test the effectiveness of the multi-component ED-LINC intervention. Patients with moderate or severe OUD seeking medical care at 2 EDs in Seattle, Washington, who provide informed consent will be randomized to the ED-LINC intervention (n=250) or usual care control (n=250) conditions.

ED-LINC will include: 1) overdose education, 2) brief bedside intervention targeting motivation to engage in outpatient care, 3) a patient-centered approach to medications for opioid use disorder (MOUD) using a treatment decision support tool, 4) longitudinal and proactive care management which will proceed for approximately 3 months, and 5) weekly caseload supervision allowing for stepped-up care targeting opioid use and comorbidity. This intervention will use the Emergency Department Information Exchange (EDIE) to re-engage patients with subsequent ED visits.

This study team developed the 'Emergency Department Longitudinal Integrated Care 2.0' intervention or 'ED-LINC' for patients with OUD to be initiated from the ED. In prior work, ED-LINC was feasible and retention in the study was high in both an intervention arm and a usual care control arm. Additionally, participants randomized to the ED-LINC arm were satisfied and acceptability of the intervention was high. Elements of ED-LINC are based on evidence-based treatments and are central components of collaborative care and will acknowledge the longitudinal care required for opioid use disorder and related substance abuse, mental health and medical comorbidity.

Arm && Interventions

Group	Intervention	Description
ED-LINC Intervention	ED-LINC	Patients assigned to the ED-LINC intervention will receive 1) overdose education, 2) brief bedside intervention targeting motivation to engage in outpatient care, 3) a patient-centered approach to MOUD using a treatment decision support tool, 4) longitudinal and proactive care management and 5) weekly caseload supervision allowing for stepped-up care targeting opioid use and comorbidity.

Primary Outcome Measures

Name	Time	Method
Initiation of Medications for OUD	12 months	To compare the frequency of initiation of medications for opioid use disorder (MOUD) where MOUD includes buprenorphine, methadone and/or naltexone in subjects receiving usual care or ED-LINC intervention over the course of the year after the index Emergency Department visit using statewide data for prescriptions and Medicaid billing data for medication administration augmented with patient self-report MOUD at scheduled follow-up intervals.
Change in Emergency Department visits	Index Emergency Department visit to 12-months followup	To compare changes over time in Emergency Department visits in subjects receiving usual care or ED-LINC intervention; Emergency Department visits will be measured by the Emergency Department Information Exchange (an automated health information exchange) that caputures population-level Emergency Department utilization for all enrolled participants.
Change in Illicit Opioid Use Over Time	Baseline ED visit and 1, 3, 6 and 12-months after ED visit	To compare self-reported past-30 day illicit opioid use using the validated self-report measure of timeline followback (TLFB) in subjects receiving usual care or ED-LINC intervention over the course of the year after the index Emergency Department visit.

Secondary Outcome Measures

Name	Time	Method
Intervention effect when associated with Methamphetamine use	Index Emergency Department visit to 12-months followup	Explore the impact of methamphetamine use, as measured by the timeline follow-back (TLFB) which is a validated patient self-report measure of days of methamphetamine use over a 30 day-period, on intervention treatment effects.
Time to Initiation of MOUD	12 months	To compare time to initiation of medications for opioid use disorder (MOUD) where MOUD includes buprenorphine, methadone and/or naltexone in subjects receiving usual care or ED-LINC intervention over the course of the year after the index Emergency Department visit.
Engagement in Medications for OUD	12 months	To compare the frequency of engagement in medications for opioid use disorder (MOUD) where MOUD includes buprenorphine, methadone and/or naltexone in subjects receiving usual care or ED-LINC over the course of the year after the index Emergency Department visit using statewide data for prescriptions and Medicaid billing data for medication administration augmented with patient self-report MOUD at scheduled follow-up intervals.
