Nature on Comparative Effectiveness research:

Where the really tough questions arise … is in how [the outcomes of Comparative Effectiveness research] will be used.

But what if treatment A is only a little bit better than B, yet costs ten times as much — is it worth it? Decisions about clinical effectiveness are difficult to divorce from those about cost effectiveness.
