Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults (18+) employed in participating law enforcement agencies in the nine Kentucky counties where SHIELD 2.0 is implemented.

Probably not a fit

Some officers or agencies may not experience changes in referrals or arrests depending on local context and implementation uptake.

What this trial studies

This is a pragmatic, quasi-experimental study that tests a structural HIV prevention intervention within law enforcement settings. The SHIELD 2.0 training is delivered with local health workers acting as champions to implement the program. Primary outcomes look at whether police reduce drug-related arrests and increase referrals to MOUD and related health services after the training. The trial combines effectiveness and implementation research to understand how well the program works in real-world police agencies across nine counties in Kentucky. Lead support comes from Johns Hopkins, with collaboration from the University of Kentucky, Northeastern University, and San Diego State University, conducted at the University of Kentucky in Lexington.

Why it matters

Potential benefit: If successful, the program could increase access to MOUD and health services for people who use drugs by changing police referral practices.

How similar studies have gone: Previous SHIELD-related efforts in other settings have shown potential for changing policing practices and increasing health referrals, though this exact Kentucky implementation is novel.
