"Naloxone distribution was cost-effective in our base-case and all sensitivity analyses, with incremental costs per QALY [Quality-Adjusted Life-Year] gained much less than $50 000 (Table 2 and Appendix Figure 3, available at www.annals.org; see Appendix Table 3, available at www.annals.org, for detailed results of selected analyses). Cost-effectiveness was similar at starting ages of 21, 31, and 41 years; the greater QALY gains of younger persons were roughly matched by higher costs.

"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.
