BACKGROUND: Opioid overdose deaths involving synthetic opioids, particularly illicitly manufactured fentanyl, remain a substantial public health concern in North America. Responses to overdose events (e.g., administration of naloxone and rescue breathing) are effective at reducing mortality; however, more interventions are needed to prevent overdoses involving illicitly manufactured fentanyl. This study protocol aims to evaluate the effectiveness of a behavior change intervention that incorporates individual counseling, practical training in fentanyl test strip use, and distribution of fentanyl test strips for take-home use among people who use drugs. METHODS: Residents of Rhode Island aged 18-65 years who report recent substance use (including prescription pills obtained from the street; heroin, powder cocaine, crack cocaine, methamphetamine; or any drug by injection) (n = 500) will be recruited through advertisements and targeted street-based outreach into a two-arm randomized clinical trial with 12 months of post-randomization follow-up. Eligible participants will be randomized (1:1) to receive either the RAPIDS intervention (i.e., fentanyl-specific overdose education, behavior change motivational interviewing (MI) sessions focused on using fentanyl test strips to reduce overdose risk, fentanyl test strip training, and distribution of fentanyl test strips for personal use) or standard overdose education as control. Participants will attend MI booster sessions (intervention) or attention-matched control sessions at 1, 2, and 3 months post-randomization. All participants will be offered naloxone at enrolment. The primary outcome is a composite measure of self-reported overdose in the previous month at 6- and/or 12-month follow-up visit. Secondary outcome measures include administratively linked data regarding fatal (post-mortem investigation) and non-fatal (hospitalization or emergency medical service utilization) overdoses. DISCUSSION: If the RAPIDS intervention is found to be effective, its brief MI and fentanyl test strip training components could be easily incorporated into existing community-based overdose prevention programming to help reduce the rates of fentanyl-related opioid overdose.

BACKGROUND: The purpose of this study was to report on feasibility, acceptability, and initial efficacy data cognitive-behavioral therapy for perceived isolation (CBT-PSI) compared to health education among individuals with opioid use disorders (OUD) reporting elevated loneliness. METHODS: Participants (n = 125) with OUD reporting elevated loneliness were recruited using online advertising to participate in a telehealth-delivered randomized clinical trial. Participants received either a 6-session CBT-PSI (n = 63) or health education (n = 62). Measures assessing loneliness, quantity of social interactions, perceived social support, substance use, substance use consequences, and treatment engagement among others, were completed at baseline, post-intervention, and 1- and 2-months post-intervention. Participants also reported on treatment acceptability for both conditions. RESULTS: Target enrollment was met with loneliness, social disconnectedness measures, and substance use reflecting a clinically severe sample. Retention was high (> 80%) for both conditions. Participants rated both Health Education and CBT-PSI as acceptable, helpful, and useful interventions to address loneliness and opioid use. Loneliness was reduced and quantity of social interactions and perceived social support were increased to the same extent for both conditions and across the follow-up assessments. Opioid use and overall substance use were reduced in both conditions; however, the reductions among participants received CBT-PSI were significantly greater compared to Health Education. CONCLUSIONS: This study supports the feasibility and acceptability of CBT-PSI. CBT-PSI findings related to loneliness, substance use, and other social connectedness outcomes are encouraging. Additional testing of CBT-PSI in a fully-powered trial is warranted.

This study evaluated the efficacy of brief cognitive behavioral therapy (BCBT) for regular methamphetamine use among methadone-maintained women. A randomized controlled trial was conducted in four methadone treatment services. Eligible women were assigned to receive either BCBT or drug education. Five questionnaires were used to assess the research hypotheses at weeks 0, 4, and 12. Urinalysis was used to verify self-reported methamphetamine use at week 0. Urinalyses were used for those participants who reported abstinence from methamphetamine at weeks 4 and 12. Overall, 120 women were enrolled. Sixteen participants were lost to follow-up. Compared with the control group, the treatment group showed significant reductions in frequency of methamphetamine use (p < 0.001), severity of methamphetamine dependence (p < 0.001), and number of days of methamphetamine use (p < 0.001) at weeks 4 and 12. Significant improvements in readiness to change (p < 0.001), psychological well-being (p < 0.001), and social functioning (p = 0.001) were found in the treatment group at weeks 4 and 12. Nineteen urine specimens (31.66%) in the treatment group were negative for methamphetamine use at post-treatment and follow-up, while no change was found in the control group (0.00%). The study supported the efficacy of BCBT for methamphetamine use and associated harms.
