Official title
The Rhode Island Prescription and Illicit Drug Study Responding to Fentanyl and Associated Harms
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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)
