## Abstract

Abstract
Military veterans in the U.S. represent one of the populations most disproportionately impacted by the current
opioid crisis. With historically high rates of injury and opioid analgesic use to treat chronic pain, veterans were
widely prescribed opioids (often in conjunction with benzodiazepines) during the early years of the epidemic,
and have been at elevated risk of opioid-related overdose and HIV/HCV infection since. Further, current data
on opioid-related harms affecting veterans are likely to understate the severity of the situation, as most studies
of veterans focus on the less than 50% of veterans who use VA healthcare facilities. Veterans who use opioids
and are not connected to the VA healthcare system have high rates of homelessness and experience higher
prevalence of comorbid substance use disorder and mental health diagnoses than their “service-connected”
counterparts. Due to these vulnerabilities and the observed barriers to testing and treatment among veterans—
especially substance- and mental health-related stigma, drug naiveté, and limited support networks—veterans
who use opioids represent a critical target for interventions designed to mitigate overdose and HIV/HCV risk
behaviors. For socially isolated veterans and veterans with limited access to healthcare, programs that work
outside of formal healthcare institutions and agencies are desperately needed. This application proposes to
advance scientific understanding of the most potent and efficient way to prevent opioid-related harms among
veterans by achieving the following Aims: 1) Evaluate the effectiveness of a peer-delivered, community-based
education, navigation and support (CENS) intervention to reduce opioid-related risk behaviors; 2) Examine
factors that mediate (e.g., knowledge, self-efficacy, self-stigma) and moderate (e.g., mental health, pain/OUD
severity, age) intervention effectiveness; and 3) Explore intervention participants’ and peer outreach staff
perspectives on implementation as well as barriers to and facilitators of intervention effectiveness. The
proposed intervention will be delivered by three veteran peer outreach workers—one dedicated to each of the
three main intervention components (Education, Navigation, and Support). The study will recruit 300 veterans
with opioid use disorder to participate in a randomized controlled trial. The CENS intervention will engage 150
participants in ongoing educational sessions, healthcare and treatment navigation, and social support
(involving both one-on-one and group social integration protocols) designed to improve self-efficacy, reduce
self-stigma, increase service and healthcare utilization, and bolster knowledge. This study stands to contribute
a timely, culturally-tailored innovation to overdose and HIV/HCV prevention-as-usual that, informed by the
theory of triadic influence, directly confronts the social, intrapersonal, and structural-level barriers to opioid-
related risk reduction among veterans. Stu...
