For decades, medicine has been dominated by fiercely independent doctors who owned their practices, worked night and day, had comfortable incomes and rarely saw their families. Now, many other young doctors are taking salaried jobs, working fewer hours, often going part time and even choosing specialties based on family reasons. The beepers and cellphones that once leashed doctors to their patients and practices on nights, weekends and holidays are being abandoned. Metaphorically, medicine has gone from being an individual to a team sport. For doctors, the changes mean more control of their personal lives but less of their professional ones; for patients, care that is less personal but, as studies have shown, more proficient. Older doctors view these changes with considerable ambivalence.
