According to SAMHSA’s 2017 National Survey on Drug Use and Health (NSDUH), 11.4 million persons in the U.S. report past-year opioid misuse; out of them, only 2.1 million individuals met criteria for an OUD. Very little is known about efficacious interventions for those who do not meet criteria for moderate/severe OUD (i.e., subthreshold OUD). The prevalence of subthreshold OUD in primary care settings is 5 percent to 10 percent, with higher rates (21 percent to 29 percent) among those receiving prescribed opioids. Although they are at high risk of developing moderate/severe OUD and/or dying from an overdose, little or no empirical evidence exists for pragmatic prevention interventions that can be adopted at integrated general medical settings. To study the efficacy of prevention interventions to arrest the progression from risky opioid use, researchers will test the efficacy of a STOP intervention in primary care settings. STOP adopts an early intervention approach, based on a collaborative care model to prevent progression to moderate/severe OUD, and consists of a practice-embedded nurse care manager who provides patient education and supports the primary care provider (PCP) in engaging, monitoring and guiding patients who have risky opioid use; brief advice delivered to patients by their PCP; and phone counseling of patients by behavioral health providers to motivate and support behavior change. Researchers will determine whether STOP reduces risky opioid use and examine the impact of STOP on progression to moderate/severe OUD, overdose risk behavior and overdose events in adults with risky use of illicit or prescription opioids.

The U.S. is in the midst of a devastating opioid epidemic. Since 1999, the number of overdose (OD) deaths involving opioids has quadrupled. These trends are magnified among American Indians/Alaska Natives (AI/ANs) compared to other racial/ethnic groups. AI/ANs are second only to Whites in the rate of OD mortality (8/100,000 versus 12/100,000 deaths, respectively). Medications for opioid use disorder (OUD; i.e., methadone, buprenorphine and naltrexone) are considered the most effective treatment, reducing mortality and increasing abstinence and retention. However, numerous barriers limit the uptake of medications for OUD in tribal communities and within urban treatment settings serving AI/AN individuals. This is a two-phase formative research study to develop and test an implementation intervention for programs to provide medications to treat OUD specifically with AI/AN consumers. The objective of Phase I (12 months) is to develop a culturally centered implementation intervention to integrate medications for opioid use disorder (MOUD) into health care/addiction specialty settings. The objective of Phase II (24 months) is to conduct a preliminary test of the implementation intervention at four sites serving AI/AN communities. Community-based participatory research (CBPR) methods will be used throughout both phases. This study will help with decreasing stigma and increase the utilization of MOUD in health care settings that serve AI/AN populations.

Emergency department (ED)-initiated buprenorphine/naloxone (BUP) with referral for ongoing BUP is superior to referral alone in engaging patients with untreated opioid use disorder (OUD) in treatment at 30 days and is cost-effective. However, logistical barriers exist in translating research into practice. New BUP formulations such as the extended-release injectable BUP (CAM2038, XR-BUP) hold promise in addressing many of the barriers more effectively than sublingual buprenorphine (SL-BUP) by treating the patients’ symptoms for up to seven days. This study will recruit, train and provide resources to 30 ED sites throughout the U.S. using implementation facilitation strategies to address stigma and provide ED-initiated BUP for patients presenting with OUD who are not receiving medications for OUD. Once implementation is adequately achieved, the sites will conduct a randomized controlled trial (RCT) to compare the effectiveness of SL-BUP versus XR-BUP on ED patients’ engagement in formal addiction treatment seven days after their ED visit. In addition, in an ancillary component of the study, the use of XR-BUP will be assessed in ED patients with Clinical Opioid Withdrawal Scale (COWS) scores of
