The Rhode Island Prescription and Illicit Drug Study Responding to Fentanyl and Associated Harms

Brown University·interventional·Posted May 1, 2020·Updated Aug 24, 2025

In Brief

A clinical study evaluating RAPIDS Intervention and Standard OEND for Opioid Overdose and Drug Overdose. Completed, enrolled 509 participants across 1 site.

Detailed Summary

This study will test the efficacy of a novel drug-checking intervention to prevent fatal and non-fatal overdose among people who use drugs (PWUD), who are 18-65 years old at the time of enrollment. The investigators will evaluate whether the incorporation of rapid fentanyl testing into a theory-driven overdose education and prevention intervention reduces rates of overdose compared to standard overdose education and naloxone distribution. Results from this study will significantly improve public health efforts to address the fentanyl overdose epidemic and reduce harms associated with exposure to drugs contaminated with fentanyl. This is a full clinical trial, building on the previously approved fentanyl-test-strip pilot study (2016-2017), the results of which have recently been published.(Krieger et al., 2018)

Interventions

RAPIDS Interventionbehavioral

RAPIDS intervention combines a behavioral intervention along with hands-on training to use fentanyl test strips.

Standard OENDbehavioral

In the attention-matched control arm, participants will receive standardized overdose education and naloxone distribution (OEND) training, with attention-control visits at 1, 2, and 3 months. Participants will receive a naloxone kit after completion of the first session, and information regarding where to obtain additional naloxone at subsequent visits. They will have contact with study staff at month 6 and 12 follow-up visits to capture outcome and covariate data.
