This issue is important from a policy perspective because certain aspects of the multi-component programs can be resource intensive.

... For example, in evaluating the effectiveness of a needle and syringe exchange component, investigators might provide a basic package of services such as voluntary HIV counseling and testing to promote behavioral change, education on needle disinfection, and referrals to health services and drug treatment in both the control and experimental
