Is this 'wealth care' or the next big thing in medicine?

How'd you like to have longer appointments with your doctor, without feeling rushed out the door? How about reaching your physician by email or cell phone at all hours? Or having extensive screenings aimed at managing or even preventing chronic illnesses?

Patients can receive this type of comprehensive service from a growing number of primary care doctors who've switched to concierge medicine. But it comes at a price, often hundreds or thousands of dollars a year, and at a time when many Americans are already struggling to afford their insurance and medical care.
