This pilot study evaluated the feasibility of the Recovery Initiation and Management after Overdose (RIMO) intervention to link individuals to medication-assisted treatment (MAT) following an opioid overdose. The study team worked with the Chicago Fire Department to train Emergency Medical Service (EMS) teams to request permission from individuals after an opioid overdose reversal to release their contact information; individuals were subsequently contacted by the study team for participation. A mixed-methods study design comprised: (1) an experimental pilot study that examined participation at each stage of the intervention and compared the odds of treatment received for individuals who were randomly assigned to either the RIMO intervention (n = 16) or a passive referral control (n = 17); and (2) a focus group that was subsequently conducted with participants in the RIMO group to obtain their feedback on the intervention components. Quantitative data was collected on participant characteristics at study intake and treatment received was based on self-report at a 30-day follow-up. The RIMO group had higher odds of receiving any treatment for opioid use (OR = 7.94) and any MAT (OR = 20.2), and received significantly more days of opioid treatment (Ms=15.2 vs. 3.4) and more days of MAT in the 30 days post-randomization (Ms=11.2 vs. 0.76), relative to the control group (all p < .05). Qualitative data illustrated that participants valued the assertive outreach, engagement, and persistent follow-up components of RIMO, which differed from their prior experiences. The pilot study suggests that the RIMO intervention is able to address the challenges of linking and engaging individuals into MAT after an opioid overdose.
