"Naloxone distribution to heroin users would be expected to reduce mortality and be cost-effective even under markedly conservative assumptions of use, effectiveness, and cost. Although the absence of randomized trial data on naloxone distribution and reliance on epidemiologic data increase the uncertainty of results, there are few or no scenarios in which naloxone would not be expected to increase QALYs [Quality-Adjusted Life-Years] at a cost much less than the standard threshold for cost-effective health care interventions. Ecological data, in fact, suggest that naloxone distribution may have far greater benefits than those forecast in this model: Reductions in community-level overdose mortality from 37% to 90% have been seen concordant with expanded naloxone distribution in Massachusetts (7), New York City (11), Chicago (10), San Francisco (9, 67, 68), and Scotland (69). Such a result is approached in this model only by maximizing the likelihood of naloxone use or by assuming that naloxone distribution reduces the risk for any overdose. Preliminary data showing that naloxone distribution is associated with empowerment and reduced HIV risk behaviors (70, 71) suggest that future research is needed to test these hypotheses."
