 Whatever our intuitions may suggest at the individual level, when we turn to a general allocation policy, it is clear that disability has a potential impact both on cost and the capacity to directly benefit, and a blanket refusal to take disability into account would be both irrational and unfair. Importantly, ignoring disability is irrational and unfair for everyone, including people with disabilities. If the presence of a disability makes a medical treatment ineffective, extremely impractical or vastly expensive, it would be foolish to ignore this fact. It would be unfair to those without a disability who need and could benefit from the treatment; but it would also be unfair for a person with a disability to ignore the fact that some of his or her needs would be unsatisfied, and some medical treatment of no use to him or her (or potentially harmful). This means that disability is not only ethically relevant at the policy level, but in fact it needs to be factored into the selection of resource or treatment and of the mode, method, and context by which the resource is delivered.
