Aims: Drug use is common in the population yet drug users are routinely excluded from research even when drug use does not medically preclude participation. We assessed the effect of a community health worker (CHW) intervention compared with additional assistance through an ambassador in enrolling drug users and non-drug users in appropriate research.

Methods: The NIDA-funded Transformative Approach to Reduce Research Disparities Towards Drug Users study randomized drug users and non-drug users to individualized study matching through a CHW or to an individualized study matching plus transportation and other assistance through an ambassador (N+) to help participants enroll in relevant research studies. Enrollment status was taken from study coordinator records. We analyzed the effectiveness of both methods in enrolling participants in research studies.

Results: The sample includes 614 18 to 85 year old community recruited adults, 329 who endorsed current drug use and 285 with no current drug use. At the 90-day follow-up, 21.2% of those randomized to CHW were enrolled in a research study compared with 36.7% of those in N+. Ambassadors increased enrollment among both drug users (19.9% CHW vs. 32.5% N+) and non-drug users (22.9% CHW vs. 41.4% N+).

Conclusion: Both the standard intervention and the ambassador intervention are effective at enrolling drug users and non-drug users in relevant research studies. The ambassador intervention significantly increased the number of both drug users and non-drug users enrolled in research studies after 90 days. These findings demonstrate that both CHWs and ambassadors can help reduce barriers and help anyone become part of the population that participates in research studies.
