Intensified screening for HIV among injection drug users receiving opioid agonist therapy could prevent more than twice as many new infections as current screening practice. A recent study based on mathematical modeling found that screening every 6 months instead of annually, and adding viral RNA testing to the currently used HIV antibody testing, could improve both effectiveness and cost-effectiveness.
Fewer than 12 percent of adolescents who meet diagnostic criteria for prescription opioid abuse or dependence receive any treatment, according to an analysis of data from the 2005 to 2008 National Survey on Drug Use and Health.
