Invited commentary: consequential(ist) epidemiology: let's seize the day.

Now is the time for the science of epidemiology to embrace its pragmatic roots. The article by Galea in this issue of the Journal (Am J Epidemiol. 2013;178(8):1185-1191) calls for us to become more "consequentialist." The Affordable Care Act allows us to access population-level databases from which we can examine how to deliver care more efficiently and cost-effectively. Asking the questions "so what" and "how much" will increase our relevance over the next decade.
