> The cost of the da Vinci robot was obtained from Intuitive Surgical. This analysis utilized the $1.5 million da Vinci-S robot. The cost of the robot was amortized over 5 years; thus, the robot costs $300,000 per year and the service contract is $112,000 per year.

So it adds the cost of one extra surgeon, for the same outcomes, but slower?

Here's a list of advantages. [1]

Or is there a bias that harder cases end up on robots, so they even “equal outcomes” is a big win for that cohort?
