It's the same logic that propels Part D. Keep seniors healthy by providing low-cost access to the medicines they need and they (1) will be healthier, more productive citizens, and (2) will not need far more costly health care interventions (i.e., hospital procedures).
Eureka -- it works. Part D has propelled millions of seniors, for the first time, to seek out and receive appropriate treatment for their chronic conditions (such as hypertension).
And that's a success that demands greater attention. It's a success that goes a long way to improving the State of the Union.
