Break-Even Cost and Return on Investment
We estimated that the cost of iBASIS-VIPP to the third-party payer (NDIS) would be offset by downstream savings at age 5.3 years, or 4 years after delivery of the preemptive intervention. By age 13 years, we estimated a savings to the third-party payer of A $3.08 (US $3.08) for each A $1.00 (US $1.00) invested in iBASIS-VIPP program delivery (A $15 826 divided by A $5131).
