Cost-Effectiveness of Naloxone Distribution

"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. In scenarios where naloxone administration reduced reliance on EMS, naloxone distribution was cost-saving and dominated (that is, less costly and more effective than) the no-distribution comparison. Cost-effectiveness was somewhat sensitive to the efficacy of lay-administered naloxone and the cost of naloxone but was relatively insensitive to the breadth of naloxone distribution, rates of overdose and other drug-related death, rates of abstinence and relapse, utilities, or the absolute cost of medical services. Naloxone was no longer cost-effective if the relative increase in survival was less than 0.05%, if 1 distributed kit cost more than $4480, or if average emergency care costs (as a proxy for downstream health costs) exceeded $1.1 million. A worst-case scenario, in which the likelihood of an overdose being witnessed, the effectiveness of naloxone, and the likelihood of naloxone being used were minimized and the cost of naloxone was maximized, resulted in an incremental cost of $14,000 per QALY gained. A best-case scenario, in which naloxone distribution reduced the risk for overdose, was dominant."
