Suppose we asked you to estimate the cost savings from a series of discrete, itemized factors. For instance, the federal government could engage in bulk buying of essential drugs in a formulary. I assume that we would give you a formulary of, say, the 150 most commonly prescribed drugs and we could ask you to estimate the potential savings from bulk buying. We could have exclusive licensing agreements with respect to certain drugs, as some countries are doing, and streamline the processing of claims. There is cost-related non-adherence, as Dr. Eyolfson has mentioned; that's the term for how much we would save from people getting access to their drugs as opposed to waiting and getting sicker without them. We could have an evidence-based formulary and increased use of generics.
If we itemized those as A, B, C, D, E, do you think you could give us rough estimates on what the cost savings from each of those elements might be?
