Table 2. Estimated costs and QALYs associated with maternal blood Hg screening and interventions versus reference case.
Analysis for discount rate of 5% Reference case Screening and intervention at Hg(Bcord)
3.4 μg/L 4.7 μg/L 8 μg/L
Abbreviations: Hg(Bcord), cord blood mercury concentration; QALY, quality-adjusted life year. The model threshold for adverse effects used in the analysis was 3.4 μg/L for all intervention thresholds investigated (3.4, 4.7, and 8 μg/L).
Costs (Can$) $2.33 $33.79 $33.82 $34.48
QALYs 18.8676 18.8694 18.8693 18.8686
Incremental costs versus reference case $31.46 $31.49 $32.14
Incremental QALY versus reference case 0.001743 0.001707 0.000945
Incremental cost per QALY gained versus reference case $18,051 $18,451 $34,017
