From what I understand, the per-patient treatments costs are both quite low and are given pro-bono, so given how GiveWell understands leverage (which @Mo Putera pointed out in the response below), they should be strongly discounted from the costs. The question of how to incorporate the infrastructure costs, ie—the hospital, staff training, etc—that enable the program to operate, is quite interesting, and I honestly don’t have a great idea how that fits into the model.
