Abstract Background and aims People who inject drugs (PWID) are at risk for adverse outcomes across multiple dimensions. While evidence‐based interventions available, services often fragmented difficult to access. We measured the effectiveness of an integrated care van (ICV) that offered PWID. Design, setting participants This was a cluster‐randomized trial, which took place in Baltimore, MD, USA. Prior randomization, we used research recruit PWID cohorts from 12 Baltimore neighborhoods...
Shared toilets in urban slums are often unclean and poorly maintained, discouraging consistent use thereby limiting impacts on health quality of life. We developed behaviour change interventions to support shared toilet maintenance improve user satisfaction. report the intervention effectiveness improving cleanliness.We conducted a cluster-randomised controlled trial among users 1226 23 Dhaka slums. assessed baseline cleanliness January 2015.
