Project OOPEN: Opioid Overdose Prevention, Education and Intervention

A Trial to Prevent Opioid Overdose: E.D. Based Intervention & Take-home Naloxone

• Status: Completed
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 256 (actual)
• Sponsor: University of Washington · Academic / Other
• Sex: All
• Age: 18 Years – 70 Years
• Healthy volunteers: Not accepted

Summary

This prospective, randomized emergency department trial will study the effectiveness of an intervention that combines opioid overdose prevention, education and intervention that includes take home naloxone with brief behavioral change counseling. The study will recruit both heroin users (n=500) and pharmaceutical opioid users at elevated risk for overdose (n=500). Outcomes of interest include subsequent opioid overdoses and overdose risk behaviors. Primary Aims The primary aims are to test whether those who receive the intervention compared to standard care have: 1) Lower rates of opioid non-fatal and fatal overdose; 2) Reduce drug use, inappropriate medication use, and other overdose risk behaviors. Secondary Aims The secondary aims are to test whether those who receive the intervention compared to standard care have: 3) More appropriate health care utilization (e.g. fewer emergency department visits and admissions to inpatient care); 4) Lower total health care costs; 5) Determine the prevalence of HIV risk behaviors among heroin and pharmaceutical opioid users at risk for overdose and whether the intervention impacts these behaviors.

Detailed description

Fatal overdoses involving pharmaceutical opioids have increased dramatically over the past decade, surpassing those related to heroin, and are the leading cause of drug overdose in much of the U.S. In Seattle-King County, 75% of drug overdoses involved pharmaceutical opioids and/or heroin in 2009. Opioid overdoses, heroin and pharmaceutical, are preventable and reversible. Research indicates that drug users and their partners can be successfully trained to recognize and reverse overdoses with naloxone (an opioid antagonist medicine or "antidote"). Despite active heroin overdose prevention, education and intervention programs with naloxone (OOPEN) in 15 states with thousands of overdose reversals and no serious adverse events, rigorous studies of these programs on rates of subsequent heroin overdoses have not been conducted. No OOPEN programs or studies have yet been implemented for pharmaceutical opioid users at elevated risk for overdose. The Emergency Department (ED) setting holds great promise for identifying and recruiting those at elevated risk of both heroin and pharmaceutical opioid overdose: 1) the ED study site for this proposal provides most services to those needing care for acute opioid related medical problems in Seattle, and 2) patients' need for urgent medical attention may heighten their concern about potential harms from opioids. Unique to this setting is the potential to identify high risk pharmaceutical opioid users, a population that is difficult to locate and engage. ED interventions using brief behavior change counseling (BBCC) have been shown to significantly improve health behaviors such as alcohol use and injury, to increase entry into drug treatment as well as to reduce costs. Evidence is promising, but limited, regarding the impact of BBCC on opioid related risk behaviors. This prospective, randomized ED trial will study the effectiveness of an intervention that combines OOPEN with BBCC for both heroin users (n=500) and pharmaceutical opioid users at elevated risk for overdose (n=500). The primary outcome is subsequent opioid overdoses, ascertained by follow up interviews conducted at 3, 6 and 12 months as well as via administrative records for up to 24 months (i.e. medical records, ambulance responses, and death certificates). Primary Aims The primary aims are to test whether those who receive the intervention compared to standard care have: 1) Lower rates of opioid non-fatal and fatal overdose; 2) Reduce drug use, inappropriate medication use, and other overdose risk behaviors. Secondary Aims The secondary aims are to test whether those who receive the intervention compared to standard care have: 3) More appropriate health care utilization (e.g. fewer emergency department visits and admissions to inpatient care); 4) Lower total health care costs; 5) Determine the prevalence of HIV risk behaviors among heroin and pharmaceutical opioid users at risk for overdose and whether the intervention impacts these behaviors.
