As doctors get a life, strains show

Young physicians are intent on balancing work and family, and as a result are giving rise to different types of practice options. But the attempt by new doctors to lead a less-pressured work life is putting additional strain on America's healthcare system. To adapt, American medicine is drifting away from the old standard of single doctor handling all of a patient's needs and toward a more team-based approach. The new system includes not only several doctors but also nurse practitioners and physician assistants.
