We compared model-projected results to published data on life-expectancy, mean VABS-3 changes, and lifetime costs. Undiscounted lifetime QALYs in the SOC and CB strategies were 40.75 and 40.91. Discounted lifetime costs in the SOC strategy were $1,014,000, and for CB ranged from $1,021,000-$1,058,000 with CB intervention cost ($8,000-$45,000). At $15,000 cost, CB was borderline cost-effective (ICER = $105,000/QALY). In one-way sensitivity analysis, CB cost and efficacy were the most influential parameters on CB ICER. CB intervention was cost-effective at costs<$15,000 and efficacies ≥2.0. Five-year healthcare payer projected budgetary outlays at a $15,000 CB cost were $3.847B.
