Brief Summary:

In this study, the investigators will investigate if there is a better intervention for patients who present to the emergency department with an overdose or with symptoms consistent with drug use. There are currently two interventions that are routinely used when a patient comes to the Emergency Department with these criteria, and the investigators will compare the two. The first is when hospital social workers uses their own previous training to help people meet their goals. The second is when a person called a peer navigator, who is someone that has been in long-term drug recovery for over two years and has completed a lot of training to work with current drug users, delivers an intervention to current drug users and uses their own training and real- life experiences to help people meet their goals. The investigators hope to determine if patients have better outcomes if they work with one of these two groups.

If a patient agrees to be in the study, the research staff will randomize them (like flipping a coin) to see if they will work with a social worker or a peer navigator. The research staff will distribute a survey in RedCap and the following information will be collected: age, sex, race, type of opioid used, and history of chronic pain, depression or post-traumatic stress disorder. Once the patient is assigned to a group, they will work with their assigned interventionist for the duration of the study. After this, the research team will track the patient to see if they joined an addiction-treatment program within 30 days of when the joined the study. The study team will also track patients to see if they had additional emergency department visits, additional overdoses, and if they successfully completed a treatment program over an 18-month period.

650 patients will be enrolled into the study.

Detailed Description:

Opioid overdoses are a leading cause of death for Americans under 50 years old, with recent years recording the most opioid overdose deaths on record. US Emergency Departments (EDs) have seen a parallel increase in opioid-related visits (a 100% increase from 2005 - 2014). ED patients presenting for an overdose are at greatly elevated risk for a repeat overdose and death. Thus, an overdose-related ED visit is both a critical and opportune time to prevent recurrent opioid overdose and overdose death through increased uptake in addiction treatment. The most effective means to promote engagement in treatment following an ED visit for opioid overdose remains unknown. To address this critical evidence gap, the investigators will compare the effectiveness of two ED-based behavioral interventions to increase treatment uptake and reduce the risk of future overdose among ED patients who are at greatest risk of accidental drug-related death.

In response to RI's overdose crisis, in 2014, the state's largest ED (Rhode Island Hospital) began a proactive campaign to improve the care of overdose patients. The program includes an ED-based behavioral intervention either by in-house clinical social work staff or peer recovery support specialists ("peer navigators"). Following the introduction of these interventions in the ED, there was 10-fold increase in the proportion of patients engaging in addiction treatment within 30 days of the initial ED visit. While this preliminary data is promising, the effectiveness of the peer navigators versus the social work intervention is not known.

The investigators propose a randomized controlled trial of early ED behavioral interventions following an opioid overdose. The investigators hypothesize that peer navigation will result in greater early treatment engagement and reduction in recurrent opioid overdose compared to a standard intervention delivered by a clinical social worker.

The investigators will determine the effectiveness of peer navigation versus a standard behavioral intervention delivered in the ED to overdose patients and those at risk of recurrent opioid overdose. A total of 650 ED patients will be recruited (n=325 per arm) and followed for 18 months. Effectiveness will be measured objectively through linkage to administrative statewide databases, with two primary endpoints: (1) engagement in formal addiction treatment (e.g., inpatient services, outpatient services, medication assisted treatment (MAT)) from a licensed substance abuse treatment provider within 30 days following the ED visit, and (2) reduction in 18-month recurrent ED visits for an opioid overdose. Exploratory outcomes of interest are: overdose fatality, repeat ED visits related to opioids, and successful completion of an addiction treatment program and/or long-term retention in MAT.

The investigators will explore if there is heterogeneity of treatment effect related to patient characteristics. The investigators anticipate that there will be individuals within each treatment arm who will vary in their response to the intervention. Specifically, the investigators will examine if the effects of the interventions are modified by baseline characteristics such as age, sex, race, type of opioid used, and history of comorbid chronic pain, depression or PTSD. Understanding these factors will allow us to further optimize subsequent interventions.

Primary Outcome Measures :
  1. The proportion of participants who are admitted to a formal addiction treatment program within thirty days following the initial ED visit. [ Time Frame: 30 days ]
    Engagement in addiction treatment will be defined as the proportion who are admitted to a formal addiction treatment program within thirty days following the initial ED visit. The research team will be using BHDDH and Prescription Drug Monitoring Program (PDMP) records. The BHDDH database contains information on all admissions to publicly funded substance abuse treatment programs in the state. The RI PDMP manages a database that contains information on all prescriptions for schedule II-IV substances filled in the state. The database is updated daily; all pharmacies are required to report prescriptions within 48-hours of the fill date. All records will be linked deterministically to participant data using identifiable information (e.g., name, social security number) within the Stronghold computing environment, a HIPAA-compliant server maintained by the team at Brown University.

  2. The proportion of participants who are treated in any Rhode Island ED for an opioid overdose at any time during the 18-month follow-up period following the initial ED visit. [ Time Frame: 18 months ]
    The proportion of participants who are treated in any Rhode Island ED for an opioid overdose at any time during the 18-month follow-up period following the initial ED visit, will be assessed by first accessing the electronic medical records (EMRs) of the 12 EDs in Rhode Island (RI) through the Rhode Island Quality Institute Statewide Health Information Exchange. This unified data system provides access to EMR data from all major health systems in RI, capturing repeat visits for an opioid overdose that occur in all 12 EDs in RI. Secondly the research team will query the RI Department of Health (RIDOH) Opioid 48-Hour Overdose Surveillance System which mandates all suspected opioid overdose cases presenting to an RI hospital be reported to the department within 48 hours. This data source will capture recurrent overdoses not identified by ICD codes in the unified EMR data system, and also contains additional fields of interest (e.g., pre-existing risk factors for overdose).

Secondary Outcome Measures :
  1. Compare the the time to subsequent opioid overdose rates between groups. [ Time Frame: 18 month ]
    The principal investigator will use Breslow's method to test if the time to subsequent opioid overdose rates differs between the groups.

  2. Successful completion or retention in addiction treatment [ Time Frame: 18 month ]
    Successful completion and/or retention in addiction treatment will be defined based on discharge data collected in BHOLD and prescription refill data in the PDMP. The principal investigator will examine the time to ED visit for an opioid overdose using a Kaplan-Meier analysis. Patients will be censored at the end of the 18-month follow-up period, considered the last point of contact.

  3. Overdose death [ Time Frame: 18 months ]
    Cox proportional hazards modeling will be used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for occurrence of repeat overdose between groups. HRs will be adjusted for clinical and demographic characteristics believed to predict the outcome of opioid overdose in order to adjust for possible residual confounding and treatment-factor interactions.

  4. Heterogeneity of intervention effect [ Time Frame: 18 months ]
    The principal investigator will perform stratified subgroup analyses to determine if treatment effects vary between groups of individuals.
