Researchers developed a mathematical model to estimate the impact of distributing naloxone, an injection or nasal spray that blocks the action of the opioid on nerve and brain cells, and triggers an instantaneous withdrawal. Based on the model, researchers estimated that giving just 200,000 heroin users naloxone kits would prevent 9,000 overdoses over their lifetimes, or one life saved for every 164 naloxone kits distributed. Using more optimistic projections, the researchers estimated that as many as 43,000 deaths could be prevented, or one life for every 36 kits. Drug overdose is the leading cause of injury death in the United States, with opioids, such as heroin and oxycodone, accounting for 80 percent of those deaths. Naloxone distribution costs about $400 for every quality-adjusted year of life gained, a measure that calculates the cost of a health intervention by including both the quantity and quality of life. Naloxone has saved an estimated 500 lives in San Francisco since 2003, when the city became the first in California to publicly fund the drug's distribution to people most likely to be in the presence of someone who is overdosing. The program costs about $73,000 a year for the drug kits, training and personnel expenses and overhead. The study was published Tuesday in the Annals of Internal Medicine. - --- MAP posted-by: Jo-D
