Combined prevention and care for HIV among persons who inject drugs (PWID) has led to dramatic reductions in injecting-related HIV transmission in a number of locations around the world. The implementation of multiple interventions at the same time has shown effects much greater than the effects of interventions given independently. This research examined the impact of giving multiple evidence-based interventions on reducing initiation into injecting drug use. The study was conducted in two sites: Tallinn, Estonia, which has very high rates of HIV infection among new drug injectors, and New York City, USA, where there is a growing problem of prescription opiate users transitioning to heroin injecting. Interventions with demonstrated effectiveness in reducing initiation into drug injecting were included, and mathematical modeling was used to examine the effects of combining the interventions. Reducing initiation into injecting drug use would not only reduce transmission of blood-borne viruses (HIV and HCV), but also lessen the many other individual and societal problems associated with injecting drug use.Abstract on NIH RePORTER
