Dallas's Parkland Hospital treats a lot of people without health insurance. On a November day in 1963, emergency room doctors at this county hospital frantically tried to save an American president who could not be saved. These days, emergency room doctors frantically try to treat 240,000 patients every year.
"So you can see we have every treatment area filled up. Beds are in the hallways and the rooms are all full," says Dr. John Pease, chief of emergency services.
