Motivational Interviewing to Increase Uptake of Drug Checking and Safe Drug Use Behaviors to Reduce Overdose
Sponsor: University of California, San Diego
Summary
A hybrid type 1 study will be conducted to evaluate efficacy and preliminary implementation considerations for a novel intervention to promote uptake of drug checking services (DCS) and safer drug use behaviors among people who use drugs (PWUD) to reduce incidence of overdose (OD) and HIV and Hepatitis C virus (HCV) infections in San Diego County. Approximately 50 syringe services programs (SSPs) in the US now offer advanced drug checking services using test strips (TS) and Fourier Transform Infrared Spectrometry (FTIR), allowing people to submit drug samples with non-nominal identifiers and obtain personalized results. While most existing FTIRs offer some counseling, no theory-based interventions to increase FTIR uptake and promote post-FTIR adoption of safer drug use behaviors have been rigorously evaluated.

MI-CHANCE (TS + FTIR + MI)
MI-CHANCE was built following key principles of MI (partnership, acceptance, compassion and evocation) to empower PWUD, help them identify potential benefits of DCS and strategies to integrate these into their daily lives. The manual follows three key stages: 1) introducing DCS, 2) generating change talk, and 3) verbalizing commitment, using open questions, affirmations, reflections and summaries. Pros and cons for regularly using FTIR and changing drug use behaviors accordingly were identified in the literature and through discussions with PWUD and peer support specialists. Peer support specialists are urged to mirror participants' own language (e.g., oxy or M30s=oxycontin; carga= heroin; malilla=withdrawal, fetty=fentanyl). Challenges were categorized into 8 key areas: legal, financial, scheduling, transportation, ability to change drug use behaviors, communication with SSP staff, managing mood and substance use.
TS + FTIR + Flu and Hepatitis A Education
Naloxone and educational materials (i.e. pamphlets) on overdose prevention, videos (English or Spanish) on naloxone, flu and Hepatitis A education.
