A doctor shortage is threatening to make the roll-out of the Affordable Care Act even more difficult — and it could create lines for care and services. New Yorkers are notorious for wanting things immediately, and that includes medical care .

I mean, you're going to have a tough time if you have all of these people demanding services at the same time," said Dr. Steven Lamm of the NYU School of Medicine.
